What Is The Working Principle Of Automotive Injection Mold?

06-05-2023

An automobile injection mold is a mold used to manufacture auto parts. Its main function is to inject molten plastic material into the mold and form parts of the required shape in the mold. Injection molds are usually composed of mold bodies and mold parts. The precision machining and combination of mold body and mold parts make the mold have a high degree of precision and complexity and can produce high-quality auto parts. Injection molds are widely used in the automobile manufacturing industry, such as manufacturing body parts, interior parts, lamps, windows, etc. The precision and quality of automotive injection molds are crucial to the manufacture of high-quality auto parts, so injection mold manufacturing is also an important part of the automotive manufacturing industry.

The working principle of automobile injection mold is based on the principle of plastic injection molding. Specifically, the automotive injection mold is to inject the molten plastic into the mold through the injection molding machine, then cool and solidifies, and finally form the required auto parts. Its specific working process is as follows:

Feeding: Add plastic granules into the hopper of the injection molding machine, and melt the plastic granules into a molten state by heating and pressure.

Injection: The molten plastic is injected into the injection port of the automotive injection mold through the injection system of the injection molding machine to fill the entire mold cavity.

Cooling: After a certain period of injection, the molten plastic begins to cool and solidify in the mold and form the desired auto parts.

Demolding: After the plastic in an automotive injection mold has cured, the mold is opened and the finished part is removed from it.

The working principle of the automotive injection mold is based on the above-mentioned injection molding process, through the high-precision processing and structural design of the mold, various complex shapes of auto parts can be manufactured.
