Detailed description of the invention
Fig. 1-5 is depicted as related description figure of the present invention; A kind of curved pin of inclined hole three core-pulling mechanisms, comprise master slider 1, compact heap 2, angled-lift splits 3, thickness adjustment plate 4, oblique top pin cover plate 5, spacing compact heap 6, oblique top pin 7, oblique top needle plate spring 8, wearing plate 9, master slider limiting plate 10, master slider spring 11, master slider pull bar 12, curved pin 13, drag link sleeve 14, as shown in Figure 1 and Figure 2.
Described oblique top pin 7 is installed in oblique top pin cover plate 5, and is installed with screw fastening by thickness adjustment plate 4; Oblique top needle plate spring 8 provides power of loosing core for loosing core of oblique top pin 7; Thickness adjustment plate 4, oblique top pin cover plate 5 are installed on angled-lift splits 3 by screw fastening.
Described angled-lift splits 3 is connect by T-slot and master slider 1; Spacing compact heap 6 is installed with on mould moving platen, for angled-lift splits 3 provides location and pressuring action; Compact heap 2 is installed on stationary mould for mould plate, for providing pressuring action when angled-lift splits 3 works, as shown in Figure 3, Figure 4.
Described master slider 1 is installed on mould moving platen, provides by curved pin 13 loose core tripping force and work thrust; The Power Component of loosing core of master slider 1 is made up of master slider limiting plate 10, master slider spring 11, master slider pull bar 12, drag link sleeve 14; Master slider limiting plate 10 controls the movement travel of loosing core of master slider 1.
Described mechanism is applicable to product dynamic model skew back hole screw column core_pulling demoulding.
Further, be coordinate the principle of this core-pulling mechanism is described, as shown in Figure 4, it is to be noted the explanation of auxiliary component: mold cores mold insert 15, die cavity mold insert 16, core fixing plate 17, core fixing plate 18.
It is to be noted in Fig. 5: H-product screw is loosed core the empty avoiding degree of depth, the S of angled-lift splits 3 on the degree of depth, w-core fixing plate 18
,-curved pin 13 Core-pulling distance distance values, S-master slider limiting plate 10 pairs of master sliders 1 loose core skid off spacing length value, S1-master slider 1 actual loose core skid off distance, H1-angled-lift splits 3 when die sinking direction displacement, H2-angled-lift splits 3 work when working horizontal direction displacement, S2-angled-lift splits 3 on master slider 1 head inclined-plane along T-slot sliding distance.Sliding motion direction when sliding motion direction, F2-master slider 1 work when ɑ-master slider 1 head inclined-plane and horizontal plane angle, β-oblique top pin 7 work with mould die sinking angular separation, F1-angled-lift splits 3.
During real work, as shown in Figure 5, its motion operation principle is as follows:
1) when oblique top pin demoulding core-pulling die is loosed core after opening, curved pin 13 starts master slider 1 and looses core by dextrad shown in F2 under the pulling of master slider spring 11, now, because spacing compact heap 6, compact heap 2 limit the direction of motion of angled-lift splits 3, so the T-slot on master slider 1 skids off pulling angled-lift splits 3 by down direction shown in F1 under the promotion of oblique top needle plate spring 8, thus drive oblique top pin 7 to extract out from product skewed screw hole post position, complete core_pulling demoulding; Its movement relation is: in order to make oblique top pin 7 exit H from product skewed screw hole post position, angled-lift splits 3 need move downward H1, and H1 and β size value is correlated with,
β=36 °; For preventing by core fixing plate 17 dieback below angled-lift splits 3, W>H1; In order to make angled-lift splits 3 move downward H1, master slider 1 certain distance S1, S1 and ɑ angle of need moving backward is relevant, ɑ=20 °; The stroke of slide block is determined: S'=S1+ (2 ~ 3) mm, S=S'+0.5mm according to S1; The effect of thickness adjustment plate 4 is to assemble fashion adjustment, avoids causing because angled-lift splits 3 and master slider 1 are joined too tightly make curved pin 13 and master slider 1 interference fit mould cannot matched moulds completely.
2) when reset product ejects rear mold reset, the pulling force that compressing master slider 1 overcomes master slider spring 11 is loosed core by left-hand shown in F2 by curved pin 13, now, because spacing compact heap 6, compact heap 2 limit the direction of motion of angled-lift splits 3, so the resistance that promotion angled-lift splits 3 overcomes oblique top needle plate spring 8 resets by up direction shown in F1 by the T-slot on master slider 1, thus promotion oblique top pin 7 resets completely, mould is completely closed, curved pin 13 pins master slider 1, and mould waits for that next injection cycle starts.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
