Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with a front mold ejector mechanism. Background Technology

[0002] Conventional injection mold design typically involves the front mold focusing on key surface features and structural design, while the rear mold serves as the primary ejection mechanism. However, with the increasing integration of functional requirements in plastic part development, many products are becoming more complex, necessitating intricate ejection mechanisms for both A and B surfaces. Most shell-type parts have internal mounting structures and external mounting clips, making conventional mold designs insufficient for ejection production needs. Therefore, we propose an injection mold with a front mold featuring a slanted ejector mechanism. Utility Model Content

[0003] The purpose of this invention is to provide an injection mold with a front mold ejector mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an injection mold with a front mold ejection mechanism, comprising a lower cover plate, a mold foot fixedly connected to the top of the lower cover plate, a rear mold fixedly connected to the top of the mold foot, a front mold disposed on the top of the rear mold, and an injection mold cavity formed between the rear mold and the front mold.

[0005] Furthermore, the top of the front mold is fixedly connected to two symmetrically arranged connecting pillars, and the top of the two connecting pillars is fixedly connected to the same top plate.

[0006] Furthermore, a front mold core plate is provided inside the front mold, and a rear mold core plate is provided inside the rear mold.

[0007] Furthermore, the front mold core plate and the rear mold core plate cooperate with each other for product molding, and the front mold is provided with an inclined ejector mechanism.

[0008] Furthermore, an ejection mechanism is provided inside the rear mold, and guide mechanisms are provided on both the left and right sides of the bottom of the front mold.

[0009] Furthermore, the ejection mechanism includes ejector pins, with two ejector pins symmetrically arranged inside the rear mold core plate. The bottom of each ejector pin passes through the rear mold core plate and the rear mold in sequence and extends to the outside of the rear mold. The bottom of the two ejector pins is fixedly connected to the same ejector pin plate.

[0010] Furthermore, a cooling pipe is provided on the right side of the rear mold.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention adds a set of inclined ejector mechanisms to the front mold on the basis of the ejection mechanism of the rear mold of a conventional mold. It is designed to achieve demolding of special structures of plastic parts. During the mold opening process, the inclined ejector mechanism of the front mold is activated by the mold hook mechanism. The inclined ejector mechanism and the product are first separated from the front mold. The inclined ejector mechanism is guided to release the product structure, thus completing the demolding of the front mold. Then the rear mold ejection action is performed to realize the demolding production of the entire injection molded product. This design mechanism can effectively realize the demolding of the snap-fit ​​structure on the front of the shell, providing convenience for injection molding production. Attached Figure Description
