Double-layer sliding type terminal cover injection mold

Abstract

The invention provides a double-layer sliding type terminal cover injection mold which comprises a left mold body and a right mold body. Injection openings are formed in the right mold body. A forming cavity is formed in the left mold body. A blocking plate is arranged at the right end of the forming cavity. Feeding holes are formed in the blocking plate. A moving block moving vertically is arranged at the left end of the forming cavity, and the moving block drives the forming cavity to vertically move. The number of the feeding holes is two, and a cooling device is arranged at the right end of the forming cavity. Injection molding is conducted on a terminal cover through the forming cavity in the left mold body, the moving block is used for driving the forming cavity to vertically move, and the cooling device is used for cooling a last position of the forming cavity, so that the phenomenon that the mold is excessively hot, and consequently equipment is damaged is avoided, and the service life of the equipment is prolonged; and in addition, position detection devices are arranged for detecting the position of the moving block, and therefore the injection molding precision is improved.

Description

technical field [0001] The invention relates to the field of terminal cover manufacturing, in particular to a double-layer sliding type terminal cover injection mold for injection molding the terminal cover. Background technique [0002] At present, when the terminal cover is manufactured, it needs to be injected with an injection mold, but the current terminal cover injection mold needs to pay attention to the temperature of the mold during injection molding, so as to prevent the mold from being damaged due to excessive temperature during injection molding. At present, the mold temperature is controlled by controlling the number of injection times, but the above method cannot be adjusted for each product, and different times need to be adjusted according to different products, which is troublesome. Therefore, it is particularly important to solve the problem of inconvenient mold temperature control during injection molding of the terminal cover. Contents of the invention ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a double-layer sliding type terminal cover injection mold for injection molding the terminal cover. The terminal cover is injected and molded through the molding cavity inside the left mold, and the molding cavity is driven to move up and down by the moving block, and cooled The device cools the previous position of the molding cavity, which solves the problem of inconvenient control of the mold temperature during injection molding of the terminal cover
