Upper cover forming mold of automobile engine junction box

Abstract

The invention discloses the field of forming molds, and particularly discloses an upper cover forming mold of an automobile engine junction box. The upper cover forming mold comprises a face plate, arunner plate, guide columns, a front mold inclined sliding block mechanism, a front mold plate, a front mold core, a rear mold core, a rear mold plate, reset springs, ejector pins, an ejector pin plate, a pressing plate, an ejector guide bush and a bottom plate. The front mold plate is fixedly connected with the front mold inclined sliding block mechanism, the front mold inclined sliding block mechanism is located below the runner plate, the runner plate is connected with the front mold plate and the rear mold plate through the guide columns, and the runner plate is fixedly connected with theface plate. By means of the runner plate, an external sizing material can enter the front mold core of the front mold plate and the rear mold core of the rear mold plate through the runner plate, theexternal sizing material can be kept stable in temperature and kept unblocked in the runner plate, and therefore the rate of finished products is increased and the product forming periodicity is reduced.

Description

technical field [0001] The invention discloses the field of molding dies, and more specifically discloses a molding die for an upper cover of an automobile engine junction box. Background technique [0002] The automobile engine junction box is composed of an upper cover and a lower cover, and the automobile engine junction box is injection molded with an injection mold. After the mold in the prior art is completed, it is often found that the exhaust is not good due to the high temperature. The resulting product yield is relatively low. At the same time, the mold structure of the upper cover of the traditional automobile engine junction box is relatively complicated. The instability of the mold in the process will affect the risk of product deformation, thus making the product molding cycle longer. Contents of the invention [0003] In view of this, the object of the present invention is to provide a molding die for an upper cover of an automobile engine junction box with...

[0002] The automobile engine junction box is composed of an upper cover and a lower cover, and the automobile engine junction box is injection molded with an injection mold. After the mold in the prior art is completed, it is often found that the exhaust is not good due to excessive temperature. The resulting product yield is relatively low. At the same time, the mold structure of the upper cover of the traditional automobile engine junction box is relatively complicated. The instability of the mold in the process will affect the risk of product deformation, thus making the product molding cycle longer
