Abstract

The invention discloses an injection mold for a foot pad of a computer case. The injection mold comprises a fixed mold body and a movable mold body. The fixed mold body comprises an upper mold plate, a concave mold fixing plate, a concave mold insert, a sprue bush, mold cavities, a guide sleeve and cooling water channels. The movable mold body comprises a convex mold insert, a convex mold fixing plate, guide columns, supporting plates, an ejector pin fixing plate, an ejector pin cushion plate, a lower mold plate, a stop pin, a sprue puller, double-joint round ejector pins, supporting columns, return pins and cooling water channels. The fixed mold body and the movable mold body are matched and connected through the guide column and the guide sleeve. The 10 cooling water channels are arranged in the injection mold for the foot pad of the computer case, so that cooling time is short, and production efficiency is high; the four supporting columns are arranged, so that the materials of the supporting plates can be reduced, and the mold cost is low; the 24 mold cavities are adopted for injection molding at the same time, so that production efficiency is high; and a convex mold and a concave mold are both made to be of an insert structure, so that replacement is convenient, and the mold cost is low.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a foot pad of a computer case. Background technique [0002] Injection molding (Injection Molding) refers to the method in which heated and melted materials are injected into the mold cavity from a state of high temperature, high pressure and high speed, and after cooling and solidification, plastic products can be obtained. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. The injection molding process can be roughly divided into the following six stages: "mold closing-injection-holding pressure-cooling-mold opening-product removal". The above process is repeated to continuously produce plastic products. [0003] However, the injection mold design of the existing computer case foot pads is unreasonable, low production efficiency, cumbersome process and high cost (the foot pads need to be used with s...
