Injection mold for auto parts

Abstract

The invention belongs to the technical field of moulds, specifically an injection mold for automobile parts, including a mold shell, a mold core, an upper rod, a return coil spring, a rotating rod, a bearing, a circular groove, a lower rod, a magnetic block, a leak-proof shell, Racks, gears, magnetic rings, moving rods, tie rods, springs, and fixed rods. The invention rotates the lower rod, the rotation of the lower rod drives the rotating rod to rotate around the bearing, and the rotation of the rotating rod increases the elastic potential energy of the return coil spring. Inside the through slot, loosen the lower rod, and under the action of the elastic potential energy of the return coil spring, the lower rod rotates back to its original position. At this time, the magnetic block fits the mold shell, and then the installation of the mold core is completed. The moving rod moves to drive the magnetic ring Move, the magnetic ring moves and the gear is separated, the moving rod moves to compress the spring, the spring is compressed to generate elastic force, the rack moves to drive the gear to rotate, loosen the pull rod, and under the action of the spring force, the magnetic ring returns to its original position and fits 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
