Automobile part injection mold

Abstract

The invention belongs to the technical field of molds, and particularly relates to an automobile part injection mold. The automobile part injection mold comprises a mold shell, a mold core, an upper rod, reset coil springs, a rotating rod, a bearing, a circular groove, a lower rod, magnetic blocks, an anti-leakage shell, racks, a gear, a magnetic ring, a moving rod, a pull rod, a spring and a fixing rod. According to the automobile part injection mold, the lower rod is rotated, the lower rod rotates to drive the rotating rod to rotate around the bearing, and the rotating rod rotates to enablethe elastic potential energy of the reset coil springs to be increased; when one side of the lower rod is completely attached to one side of the upper rod, the upper rod and the lower rod are insertedinto the circular through groove, the lower rod is loosened, under the action of the elastic potential energy of the reset coil springs, the lower rod rotates to restore the original position, at themoment, the magnetic blocks are attached to the mold shell so as to complete the installation of the mold core; and the movable rod moves to drive the magnetic ring to move, the magnetic ring moves to be separated from the gear, the movable rod moves to compress the spring so that the spring is compressed to generate elastic force, the rack moves to drive the gear to rotate, then the pull rod isloosened, and under the action of the elastic force of the spring, the magnetic ring is restored to the original position so as to be attached to the gear.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an injection mold for auto parts. Background technique [0002] In the mold industry, various molds and tools are used for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make a molded product. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] The currently used injection molds have certain defects, such as the lack of a convenient replacement function for the mold core. The mold core is generally fixed inside the mold shell, which is inconvenient to replace the mold core and reduces the practicability of the mold. At the same time, the mold shell lacks a leak-proof mechani...

Problems solved by technology

[0003] The currently used injection molds have certain defects, such as the lack of a convenient replacement function for the mold core. The mold core is generally fixed inside the mold shell, which is inconvenient to replace the mold core, which reduces the practicability of the mold. At the same time, the mold shell lacks a leak-proof mechanism. When the mold shell is injected, the injection material will flow out from the circular through hole, polluting the working environment
