Drawings

FIG. 1 is a schematic side sectional structure view of the fixed mold of the present invention (the push plate is located at the injection molding station);

wherein: 100. a deep cavity plastic product; 10. fixing a template; 101. a base body; 102. pushing the plate; 11. a mold insert; 20. a push rod; 31. a travel switch; 32. a travel switch stop block.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an injection mold for a deep cavity plastic product 100 includes a fixed mold and a movable mold, the fixed mold includes a fixed mold plate 10, a fixed mold core fixed on the fixed mold plate 10, and a mold core insert 11 fixed to the fixed mold core, the fixed mold core includes a base 101 and a push plate 102 movably disposed along an up-down direction relative to the base 101, the push plate 102 has an injection molding station closed to the base 101, and an unloading station far away from the base 101 and ejecting an injection molded product upward from the mold core insert 11. In this embodiment, the number of the mold insert 11 is two, there is only one push plate 102, the seat body 101 is provided with a mounting groove, when the push plate 102 is located at the injection molding station, the push plate 102 is located in the mounting groove, the peripheral groove wall of the mounting groove extends obliquely from bottom to top to the outer side, the peripheral surface of the push plate 102 extends obliquely from bottom to top to the outer side, the push plate 102 and the mounting groove are arranged in a matching cone shape, and when the push plate 102 falls back down, the situation that the push plate 102 and the seat body 101 are scratched at the notch of the mounting groove due to slight inclination can be avoided.

In this embodiment, the push plate 102 is sleeved on the periphery of the mold insert 11, and the push plate 102 can jack up the deep cavity plastic product from the edge thereof. The injection mold further comprises a push rod 20, one end of the push rod is fixedly connected with the push plate 102, the other end of the push rod 20 downwards penetrates through the fixed mold, and the lower end of the push rod 20 is fixedly connected with a top shaft of the injection molding machine.

In addition, the injection mold further comprises a travel switch 31 arranged on one side surface of the seat body 101 and a travel switch stopper 32 fixed on one side surface of the push plate 102. When the push plate 102 returns to the injection molding position, the top shaft of the injection molding machine stops moving in time, so that the situation that the downward extrusion force of the push plate 102 and the seat body 101 is too large, and parts are damaged is avoided.

The utility model discloses an injection mold of plastic product, after the product is moulded plastics and is accomplished, the injection molding machine apical axis promotes the ejector pin upward movement, and the ejector pin then drives push pedal 102 upward movement, and push pedal 102 then drives the product and breaks away from mould benevolence mold insert 11, and push pedal 102 upward movement's distance can directly have the ejecting control of injection molding machine.

To sum up, the utility model discloses an injection mold of dark chamber plastic product, through carrying out components of a whole that can function independently setting to the cover half benevolence, let the push pedal of cover half benevolence can fluctuate to accomplish after the product is moulded plastics and is accomplished, utilize the apical axis of injection molding machine top power, drive the push pedal and move up, the product is ejected upwards in the process that the push pedal moves up, because the push pedal belongs to a part of cover half benevolence, its top pushes away the position and can completely coincide with the border of product, push out the product from the border of product, the atress is even when the product is ejected, can not lead to the product to damage, avoid extravagant, improve enterprise economic benefits; furthermore, the utility model discloses an injection mold avoids the use of liftout mechanism commonly used among the prior art, and mould simple structure, convenient assembling, greatly reduced mould cost of manufacture.

The present invention has been described in detail, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the protection scope of the present invention should not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
