Injection molding machine for auto parts

Abstract

The invention relates to the technical field of injection molding machines, and discloses an injection molding machine for auto parts. The injection molding machine comprises an injection machine body, the right side of the upper surface of the injection machine body is fixedly connected with a driving device, and the middle of the upper surface of the injection machine body is fixedly connected with a heat preservation device. The outer surface of an injection cylinder is fixedly connected with a heat preservation annular sleeve, the outer surface of an injection screw rod is closely attachedto the interior of the injection cylinder, water in a heating box is heated through a heating element in the heating box, the heated water transfers heat to the injection cylinder through the heat preservation annular sleeve, thus the injection cylinder is kept to be the same as an internal melting milk material in temperature, the situation that a fixed film is generated due to the large temperature difference of the injection cylinder and the melting milk material in the injection cylinder is effectively avoided, the through-flow area in the injection cylinder is guaranteed, and the injection molding rate of the injection molding machine is increased; and meanwhile, it is guaranteed that the injection screw rod can horizontally rotate and move in the injection cylinder, and thus the injection molding precision of the injection molding machine is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine for auto parts. Background technique [0002] Auto parts are the various units that constitute the whole car and a product that serves the car. There are many types of auto parts. With the improvement of people's living standards, people consume more and more cars. The market for auto parts has become It is also getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. The working principle of the injection molding machine is similar to that of the syringe for injection. It uses the thrust of the screw or plunger to melt the plasticized molten state ( That is, the plastic in the viscous flow state) is injected into the closed mold cavity, and the finished product is obtained after curing and shaping. [0003] The existing accessory injection molding machine pushes the injection molding raw ma...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an injection molding machine for auto parts, which has the advantages of improving the injection molding speed and injection precision of the injection molding machine and protecting the finished product after injection, and solves the problem of the relatively large temperature difference between the existing injection molding push cylinder and the melted milk material. Large, so it is easy to form a solidified layer inside the injection push cylinder, which reduces the flowable area of ​​the injection push cylinder channel, affects the amount of injection molding raw materials injected at the same time, and reduces the injection rate of the injection molding machine, and the existing After the injection molding machine injects the material into products, the bottom of the demoulding mechanism is not equipped with a good material receiving mechanism, so that the injection molded finished products are easy to pile up together or fall off the demoulding mechanism directly and fall to the hopper Easy to cause damage to the injection molded finished product
