A versatile plastic mold system for pressure forming, extrusion, injection molding, blow molding, and low foam molding, it mainly includes a mold cavity with variable cavity shape, consisting of a mold base, mold components, and mold assembly plate, and a core with variable core shape, made up of a core base, core components, core assembly plate, cavity cutting components, and side cutting assembly board. The coordinated variation of mold male and female components and auxiliary molding systems. Capable of processing a series of plastic parts with various shapes and sizes. A tool that provides complete structure and size to plastic products in the plastic processing industry and plastic molding machine matching. Due to the wide variety of plastic types and processing methods, and the differing complexities in the structure of plastic molding machines and plastic products, the types and structures of plastic molds are also highly diverse.

As the plastic industry rapidly advances and the strength and other properties of general and engineering plastics continuously improve, the application scope of plastic products is expanding, and the consumption of plastic products is on the rise.

Plastic molds are tools used for producing plastic products. Composed of several component parts, they house a mold cavity. During the injection molding process, the mold is clamped onto an injection molding machine, where molten plastic is injected into the mold cavity and cools and solidifies within it. Once cooled, the mold halves are separated, and the finished product is ejected from the cavity using the ejection system, after which the mold closes to begin another injection cycle. The entire process is a continuous loop.

Generally, plastic molds consist of two parts: the moving mold and the stationary mold. The moving mold is mounted on the moving template of the injection molding machine, while the stationary mold is installed on the fixed template. During the injection molding process, the moving and stationary molds close to form the gating system and the mold cavity. When the mold is opened, the moving and stationary molds separate to allow for the removal of the plastic product.

Although the structure of molds may vary greatly due to different plastic types and properties, the shapes and structures of plastic products, and the types of injection machines, the basic structure remains consistent. Molds are primarily composed of the gating system, temperature control system, molding parts, and structural parts. The gating system and molding parts are the parts that come into direct contact with the plastic and the products, and they vary with the plastic and the products. They are the most complex, variable, and require high surface finish and precision in plastic molds.

The injection system refers to the channel portion of plastic before it enters the mold cavity, including the main runner, cold slug well, divergent channel, and gate, etc. The molded part refers to various components that form the shape of the product, including the moving mold, fixed mold, mold cavity, core pins, molding rods, and exhaust ports, etc.

Under the impetus of high-tech driving and the application demands of pillar industries, China's plastic mold industry has formed a massive industrial chain, ranging from upstream raw material and processing industries, as well as inspection equipment, to downstream application industries such as machinery, automobiles, motorcycles, home appliances, electronic communication, and construction materials, where the plastic mold sector is thriving.
