Automobile engine cover injection mold

Abstract

The invention discloses an automobile engine cover injection mold, and relates to the technical field of injection molds. The automobile engine cover injection mold comprises a fixed mold and a movable mold, wherein a plurality of positioning columns are fixedly connected to one surface of the fixed mold, a plurality of positioning holes are formed in one surface of the movable mold, and the positioning columns are in sliding fit with the positioning holes. According to the injection mold, through the use of an injection molding channel, a glue gun channel, a spring, a disc and a limiting block, the glue gun can enter the fixed mold, and the length of the injection molding channel is shortened, so that the size of an injection head is reduced after an injection part is formed, and raw material is saved; the glue gun directly enters the fixed mold, so that the coaxiality of the glue gun and the injection molding channel is better, the situation of deviated glue injection is reduced, andthe glue injection stability is indirectly improved; and by using a pipeline support and locking buckles, when the pipeline support fixes an external oil pipe and a water pipe which are connected with the fixed mold and the movable mold, the pipes can be fixed, and the pipes are prevented from being wound.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to an injection mold for an automobile engine cover. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. In the automotive industry, engine covers are often mass produced using injection molds to save costs. [0003] However, when the existing injection mold is in use, the glue gun is generally concentric with the injection channel and offsets. After the injection is cooled, the injection head will fill the entire injection channel. If the in...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of injection mold for automobile engine cover, to solve the problem that when the existing injection mold is in use, the glue gun is generally concentric with the injection channel and offsets. After the glue is cooled, the injection head will fill the entire injection channel. If the injection channel Too long will lead to waste of raw materials. Then, when the cooling channel of the mold is connected with the external oil pipe or water pipe, the pipe is easy to be entangled. In addition, the cooling pipe of the existing mold is generally connected with a single nut when connected with the external pipe, which is inconvenient to install. , on the other hand, a set of fixed mold and movable mold generally only install a set of convex mold surface and concave mold surface, the problem of high manufacturing cost
