To sum up, implement the embodiment of the utility model provides a, will have following beneficial effect: the anti-sticking assembly of the scheme is applied to a mold, and besides the mold has excellent injection molding efficiency, the anti-sticking assembly can also prevent the injection molding piece 90 from being bonded on the sliding block. Specifically, the mold includes a first mold body 10 and a second mold body 20 enclosing a molding space. The first mold 10 and the second mold 20 are relatively movable in a first direction to open and close the mold, wherein the first mold 10 includes a first body 11. Further, the anti-sticking assembly comprises a first slide block 12 and a second slide block 13 which are accommodated in the injection molding space, and the second slide block 13 is arranged on the first slide block 12 and can slide relative to the first slide block 12. The shape of the injection molded part 90 can be defined through the second mold body 20, the first body 11, the first slider 12 and the second slider 13, so that the injection molded part 90 originally covers the whole slider and is shared between the first slider 12 and the second slider 13. Further, the second mold body 20 moving in the first direction can drive the first slide 12 to slide in the second direction relative to the first body 11 and limit the second slide 13 to move in the second direction. So when making injection molding 90 to mould plastics and accomplish, when the second die body 20 removed the die sinking along first direction, first slider 12 was thereupon separated with injection molding 90, and second slider 13 did not take place to remove and supported injection molding 90, because the existence of second slider 13, reduced the cladding in injection molding 90 area on first slider 12, the power of holding tightly that leads to producing is less to reduce the risk that injection molding 90 bonded in first slider 12, avoid injection molding 90 to be damaged by the pulling. Meanwhile, the distribution influence of the scheme on the water transportation system in the first sliding block 12 is small, and the efficiency of cooling the injection molding part 90 is ensured, so that the production efficiency is improved.

In one embodiment, as shown in FIGS. 3, 5, 6, 9 and 16, the second mold body 20 is provided with a first surface 21. The first surface 21 extends in a first direction and is perpendicular to a second direction. The second slider 13 is provided with a second surface 131. The second surface 131 is capable of engaging the first surface 21 when the second mold body 20 is moved in the first direction. The movement of the second slider 13 is thus limited by the cooperation of the first surface 21 and the second surface 131 to abut the injection molded part 90 when the first slider 12 is separated from the injection molded part 90, the separation of the first slider 12 from the injection molded part 90 being achieved by the relative sliding of the first slider 12 and the second slider 13. In this embodiment, since the first surface 21 and the second surface 131 are both parallel to the first direction, when the first surface 21 moves along the first direction with the second mold body 20, the first surface 21 can slide relative to the second surface 131 without driving the second slider 13, and can limit the second slider 13 from moving along the second direction, so as to ensure the stability of the second slider 13 abutting against the injection molded part 90. It is understood that in other embodiments, the second mold body 20 may further be provided with a positioning member to fix the position of the second slide 13, such as a rod-shaped structure such as a pin.

The initial position is the position of the first slide block 12 during injection molding, and the shape of the injection molded part 90 is defined by the second mold block 20, the first body 11, the first slide block 12 and the second slide block 13. During the die sinking, second die body 20 moves along first direction, and the first slider 12 of drive moves to the first position by initial position along the second direction, and first surface 21 and the laminating of second surface 131 and relative slip to restriction second slider 13 removes, thereby guarantees that second slider 13 butt injection molding 90, realizes first slider 12 and the separation of injection molding 90. Further, when the first slider 12 slides from the first position to the second position, the first surface 21 is separated from the second surface 131, and the first slider 12 can drive the second slider 13 to move in the second direction. Specifically, the second mold body 20 continues to move in the first direction while the first surface 21 moves out of the second surface 131 with the movement of the second mold body 20, i.e., while the first surface 21 and the second surface 131 do not overlap in the second direction. At this time, the first slide block 12 continues to move in the second direction through the movement of the second mold body 20 in the first direction, and then the second slide block 13 is driven to move in the second direction, so that the separation of the second slide block 13 from the injection molded part 90 is realized. The way in which the first slider 12 drives the second slider 13 can be achieved by friction, i.e. the second slider 13 engages with the second slider 13 by gravity and moves with the first slider 12. In another embodiment, the first slider 12 and the second slider 13 are provided with concave-convex portions arranged oppositely along the second direction, and the driving of the second slider 13 by the first slider 12 is realized through the matching of the concave-convex portions.

The first elastic member 14 is capable of generating a driving force that drives the second slider 13 to move in the second direction. The first elastic part 14 is arranged to provide abutting force when the first surface 21 and the second surface 131 are attached to each other, so that the matching precision of the first surface 21 and the second surface 131 is ensured, the second surface 131 is prevented from being separated from the first surface 21, the abutting force of the first sliding block 12 on the injection molded part 90 is reduced, and the injection molded part 90 is prevented from loosening to influence the separation of the first sliding block 12 from the injection molded part 90. Simultaneously, the setting of first elastic component 14 can also avoid first slider 12 to the rigid drive of first slider 12, realizes flexible drive through first elastic component 14 setting between first slider 12 and second slider 13, avoids because the influence of machining precision and expend with heat and contract with cold, and the reduction of the cooperation precision between first slider 12, second slider 13 and the second die body 20 causes the emergence of the dead phenomenon of lock. Specifically, when the fitting accuracy is low, the first elastic member 14 can be deformed by itself to adjust the positions of the first slider 12 and the second slider 13, so as to avoid the occurrence of the locking phenomenon. In this embodiment, the first elastic member 14 is a spring, which extends along the second direction and can provide a driving force along the second direction. In order to improve the driving stability, in the present embodiment, the number of the first elastic members 14 is plural and is distributed in the direction perpendicular to the second direction.

In one embodiment, as shown in fig. 3, 9 and 16, the first slider 12 is provided with a stop member 15, and the stop member 15 is used for limiting the range of the first elastic member 14 driving the second slider 13 to move along the second direction. The moving range of the second slide block 13 can be limited by the arrangement of the stop part 15, and the second slide block 13 can be at a preset position when die assembly is carried out, so that interference caused by die assembly is avoided. In the present embodiment, the stopper 15 is detachably connected to the first slider 12 by a bolt, and can be replaced when the stopper 15 is damaged. In another example, the first sliding block 12 is provided with a plurality of positions for installing the stop member 15, so that the moving range of the first sliding block 12 can be adjusted conveniently by installing the stop member 15 at different positions. It will be appreciated that in other embodiments, the stop member 15 may be integrally formed with the first slider 12, facilitating manufacture of the integral molding.

In one embodiment, as shown in FIGS. 3, 6, 9 and 16, the second mold body 20 is provided with a third surface 22. The third surface 22 is inclined to the initial position with respect to the first surface 21. The second slider 13 is provided with a fourth surface 132 parallel to the third surface 22. The second mold body 20 moving in the first direction can drive the second slider 13 to move in the second direction to the initial position side and make the third surface 22 and the fourth surface 132 fit. So can lock second slider 13 through the cooperation of third surface 22 and fourth surface 132, avoid second slider 13 to take place to remove in the process of moulding plastics and influence injection molding 90 and reach preset shape. In this embodiment, the first surface 21 and the third surface 22 are integrally connected, and similarly, the second surface 131 and the fourth surface 132 are integrally connected. During mold closing, the end of the first surface 21 away from the third surface 22 first contacts the fourth surface 132, and the second slide 13 is driven to move to the initial position side by sliding relative to the fourth surface 132 until the third surface 22 abuts against the fourth surface 132.

Further, the connecting block 133 is detachable, and is convenient to replace when the second surface 131 or the fourth surface 132 on the connecting block 133 is worn.

In one embodiment, as shown in fig. 13 and 17, the mold further includes a resilient component 30. The elastic member 30 is disposed between the first body 11 and the first slider 12. In the initial position, the elastic member 30 can be compressed to generate a driving force in the second direction. Thus, during the initial stage when the second mold body 20 drives the first slider 12, the driving force provided by the elastic component 30 can assist in driving the first slider 12, and facilitate the quick separation of the first slider 12 from the injection-molded part 90. In this embodiment, the positions of the elastic element 30 and the second mold body 20 are opposite to each other along the second direction, so as to ensure the stability of the movement of the first sliding block 12.

Further, a through hole 310 is formed in the bracket 31, and the second elastic element 32 can drive the driving element 33 to penetrate through the through hole 310. Therefore, when the mold is opened, the driving member 33 can penetrate through the through hole 310 to contact with the first body 11, so as to assist in driving the first sliding block 12 to move.

In one embodiment, as shown in fig. 2 and 5, the first slider 12 is provided with a first inclined guide portion 122. The second casing 20 is provided with a second inclined guide portion 23. Movement of the second housing 20 in the first direction moves the first angled guide portion 122 relative to the second angled guide portion 23 to actuate movement of the first slide 12 between the initial position and the second position. In this embodiment, the first inclined guiding portion 122 is an inclined hole, and the second inclined guiding portion 23 is an inclined guide post, so that the second mold body 20 moves along the first direction to drive the first slide 12 to move along the second direction.

In one embodiment, as shown in fig. 2, 13 and 14, the first slider 12 is provided with first pressing blocks 16 at both ends thereof, respectively. The first pressing block 16 is connected with the first body 11 and is used for attaching the first sliding block 12 to the first body 11. Therefore, the first sliding block 12 is ensured to be attached to the first body 11 through the arrangement of the first pressing block 16, and the stability of the movement of the first sliding block 12 relative to the first body 11 is further ensured. Further, a first sliding portion 161 is disposed on one side of the first pressing block 16 close to the first body 11, the first sliding portion 161 extends along the second direction, a second sliding portion slidably connected to the first sliding portion 161 is disposed on the first sliding block 12, and the first pressing block 16 fits the first sliding block 12 to the first body 11 through the cooperation of the first sliding portion 161 and the second sliding portion. In this embodiment, the first sliding portion 161 is a notch formed on the first pressing block 16, and the second sliding portion is a protrusion, and the notch and the protrusion cooperate with each other to attach the first slider 12 to the first body 11.

In one embodiment, as shown in fig. 3 and 16, two ends of the second slider 13 are respectively provided with a second pressing block 17, and the second pressing block 17 is connected with the first slider 12 and is used for attaching the second slider 13 to the first slider 12.

Furthermore, a third sliding portion 171 is disposed on one side of the second pressing block 17 close to the first sliding block 12, the third sliding portion 171 extends along the second direction, a fourth sliding portion connected to the third sliding portion 171 in a sliding manner is disposed on the second sliding block 13, and the second pressing block 17 fits the second sliding block 13 to the second sliding block 13 through the cooperation of the third sliding portion 171 and the fourth sliding portion. In this embodiment, the third sliding portion 171 is a notch formed in the second presser 17, and the fourth sliding portion is a protrusion, and the notch and the protrusion cooperate with each other to attach the second slider 13 to the first slider 12.

In one embodiment, as shown in fig. 2, the mold further includes a driving mechanism 40, and the driving mechanism 40 can drive the first slide 12 to move from the second position to the side away from the first position along the second direction. Since the second casing 20 is moved in the second direction by moving the first slide 12 in the first direction, the second casing 20 has a limited distance to move the first slide 12. Therefore, the moving distance of the first slider 12 can be increased by providing the driving mechanism 40. Because the second slide block 13 is arranged on the first slide block 12, the arrangement of the driving mechanism 40 can also improve the moving distance of the second slide block 13, so that the mold in the embodiment can adapt to long-stroke core pulling and can be separated from a larger back-off position on the injection molding part 90. It is understood that in other embodiments, the first slide 12 may be moved only by the driving mechanism 40, the second mold body 20 is only used for stopping the movement of the second slide 13, and when the first slide 12 reaches the predetermined position, the second mold body 20 is separated from the second slide 13, so that the driving mechanism 40 drives the first slide 12 while the second slide 13 moves together with the first slide 12. In the present embodiment, the driving mechanism 40 is an oil cylinder mechanism.

In one embodiment, as shown in fig. 2 and 4, the mold further includes a limit switch 50 and a trigger 60. The limit switch 50 includes a first contact 51 and a second contact 52. The trigger 60 is provided to the first slider 12. When the first slider 12 is in the second position, the trigger 60 contacts the first contact 51 to trigger the opening actuator 40. The trigger 60 moves in the second direction with the first slider 12 into contact with the second contact 52 to trigger the closure drive mechanism 40. Therefore, the opening and closing of the driving mechanism 40 can be automatically controlled by moving the first sliding block 12 to different positions, and the demolding can be conveniently and automatically completed. Meanwhile, when the first sliding block 12 reaches the preset position, the driving mechanism 40 can be instantly opened and closed, so that the smooth demolding process is ensured, and the production efficiency is improved.

In one embodiment, as shown in fig. 4, the first contact 51 and the second contact 52 are provided with a roller 53, and the trigger 60 is provided with a guide surface 61 for contacting the roller 53. The guide surface 61 contacts the roller 53, thereby driving the first contact 51 and the second contact 52 to be opened. The above arrangement can reduce the impact of the trigger 60 on the first and second contacts 51 and 52, thereby improving the life of the first and second contacts 51 and 52. In this embodiment, the first contact 51 and the second contact 52 are connected to the first body 11 through the frame 54, and both the first contact 51 and the second contact 52 can move relative to the frame 54. The guide surface 61 contacts with the roller 53 on the first contact point 51, and the roller 53 drives the first contact point 51 to move relative to the frame 54, thereby triggering the driving mechanism 40 to open. The guide surface 61 contacts the roller 53 on the second contact point 52, and the roller 53 drives the second contact point 52 to move relative to the frame 54, thereby triggering the driving mechanism 40 to close. It is understood that in other embodiments, the first contact 51 and the second contact 52 may also be laser sensors, and the driving mechanism 40 is turned on and off by shielding the first contact 51 and the second contact 52 from the laser by the trigger 60.

In one embodiment, as shown in fig. 10, 11, 14 and 15, one of the first body 11 and the first slider 12 is provided with a plurality of position-limiting portions, and the other of the first body 11 and the first slider 12 is provided with a position-limiting assembly 70, and the position-limiting assembly 70 can cooperate with the position-limiting portions in turn to determine the position of the first slider 12 relative to the first body 11 along with the relative movement of the first body 11 and the first slider 12 along the second direction. Thus, whether the first sliding block 12 moves to the preset position can be determined by the cooperation of the limiting component 70 and the limiting parts. For example, the aforementioned initial position, the first position and the second position, by providing three position-limiting portions, that is, the first position-limiting portion 123, the second position-limiting portion 124 and the third position-limiting portion 125 are respectively corresponding to the initial position, the first position and the second position, when the position-limiting assembly 70 is engaged with the first position-limiting portion 123, the first sliding block 12 is located at the initial position; when the limiting assembly 70 is matched with the second limiting part 124, the first sliding block 12 is located at the first position; when the position limiting assembly 70 is matched with the third position limiting part 125, the first sliding block 12 is located at the second position. The spacing portion and the spacing assembly 70 may be snap fit, forming a certain resistance when fitting, ensuring the stability of the first slider 12 in the predetermined position. It is understood that in other embodiments, the stopping portion and stopping assembly 70 may also be a sensor that, when engaged, generates an electrical signal to control the driving unit that drives the second mold body 20 and the driving mechanism 40 that drives the first slide 12, ensuring that the first slide 12 is stable in the predetermined position.

In one embodiment, as shown in fig. 11, 15 and 18, the stop portion is a groove. The position limiting assembly 70 includes a position limiting member 71, a third elastic member 72 and a guide member 73. When the limiting component 70 moves to be opposite to any limiting part, the third elastic component 72 can drive the limiting component 71 to move relative to the guiding component 73 and extend into the limiting part. Thus, by the cooperation of the limiting member 71 and the limiting portion, the first slider 12 is stably positioned, and the first slider 12 is prevented from moving near the predetermined position.

In one embodiment, as shown in fig. 11 and 15, the position-limiting portions are located on the first slider 12 and distributed along the second direction. The first body 11 is provided with a second sink 111. The guide 73 is provided at the bottom of the second sinking groove 111. The limiting member 71 is at least partially received in the second sinking groove 111. The third elastic element 72 is located in the second sunken groove 111, and the first slider 12 can press the limiting element 71 to the bottom of the second sunken groove 111, so that the limiting element 71 compresses the third elastic element 72. Thus, when the limiting member 71 is opposite to the limiting portion, the third elastic member 72 can drive the limiting member 71 of the limiting member 71 to be matched with the limiting portion, and when the limiting member 71 is opposite to the non-limiting portion of the first sliding block 12, the first sliding block 12 can press the limiting member 71 into the second sinking groove 111, so as to avoid the interference caused by the movement of the first sliding block 12 by the limiting member 71. That is, the limiting member 71 can provide a resistance to the first sliding block 12 when the first sliding block 12 is at the preset position to determine that the first sliding block 12 is at the preset position, and when the first sliding block 12 is at the non-preset position, the limiting member 71 does not affect the movement of the first sliding block 12, i.e., whether the first sliding block 12 is at the preset position can be determined by the change of the resistance of the first sliding block 12. The change in resistance of the first slider 12 can be detected by a sensor.

In one embodiment, as shown in fig. 11 and 18, the limiting member 71 is provided with a rolling part 711 on a side facing the first slider 12, and the rolling part 711 can roll relative to the first slider 12 and can partially extend into the limiting part. The movement of the position-limiting member 71 relative to the first slider 12 is facilitated by the arrangement of the rolling portion 711, and when the rolling portion 711 is engaged with the position-limiting member, that is, the rolling portion 711 partially extends into the position-limiting member, so that the rolling portion 711 rolls out of the position-limiting member while providing the movement resistance of the first slider 12, so as to facilitate the first slider 12 to continue to move. Preferably, the rotation axis of the rolling part 711 is located outside the stopper part. The limiting part is a V-shaped groove.

In an embodiment, with reference to fig. 11 and fig. 18, the limiting member 71 has a protrusion 712 on a side facing the first slider 12, and the rolling portion 711 is disposed on the protrusion 712. The arrangement of the protruding portion 712 can increase the compression amount of the first slider 12 driving the limiting member 71 to compress the third elastic member 72, so as to increase the driving force of the third elastic member 72 driving the limiting member 71, so that the limiting member 71 can be rapidly matched with the limiting member when facing the limiting member. Further, the rolling part 711 protrudes at least partially from the protruding part 712. This is so that the arrangement of the projecting portion 712 does not affect the rolling of the rolling portion 711 with respect to the first slider 12 and the rolling-in and rolling-out from the stopper portion. The rolling part 711 may be a ball. In the present embodiment, the rolling portion 711 is a roller, and the roller is in line contact with the first slider 12, so that abrasion of the first slider 12 can be reduced.

In one embodiment, as shown in fig. 12 and 19, one of the first body 11 and the first slider 12 is provided with a first catching member 126, and the other of the first body 11 and the first slider 12 is provided with a second catching member 112. The relative movement of the first body 11 and the first slider 12 along the second direction can make the first clamping piece 126 and the second clamping piece 112 approach each other and clamp to limit the moving range of the first slider 12. Further, the first clamping member 126 is a rod, and the second clamping member 112 is provided with a clamping groove 1121 matched with the first clamping member 126. In this embodiment, the first clamping member 126 is disposed through the first sliding block 12. The second clamping piece 112 is arranged on the first body 11. The first clamping member 126 can be clamped with the second clamping member 112 close to the second clamping member 112 along with the movement of the first slider 12, so as to prevent the first slider 12 from continuously moving. When the first clamping piece 126 and the second clamping piece 112 are clamped, the first sliding block 12 moves to the end position, the demolding is completed, and the first sliding block 12 is limited to continue moving to cause danger.

In one embodiment, as shown in fig. 2 and 8, wear plates 80 are provided between the contact surfaces of the first and second casings 10, 20 and the contact surfaces of the first slide 12 and the first body 11 to reduce the amount of wear during relative movement. As shown in fig. 11, at the location where the stop assembly 70 is located, the wear plate 80 is provided with a through slot 81 to form a receiving cavity with a second countersunk slot 111 for receiving the stop assembly 70.

In one embodiment, as shown in fig. 9, the second slider 13 is provided with an abutting surface 134 abutting against the injection-molded part 90, and the abutting surface 134 can be configured as a smaller plane to reduce the size of the clamp line formed on the injection-molded part 90.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
