A Combined plastic mold for pressure plastics, extrusion plastics, injection molding, blow molding plastics and low pressure molding, which mainly includes a concave mold combined base plate, a concave mold assembly and a concave mold combined card board to form a variable-type concave cavity, a punch Combination base plate, punch assembly, punch combination card plate, cavity section assembly and side cut combination plate make up a variant core that can have punches. Machining the mold and supporting the coordination of the molding system. Manufactures a range of plastic parts in different shapes and sizes. In the plastic processing industry and plastic molding machines, plastic products are given full configuration and precise sizing tools. Due to the wide variety of plastics and different processing methods, the structure and characteristics of plastic molding machines and plastics are different, and the types and structures of plastic molds are also different.

With the development of the plastics industry and General Motors and the continuous improvement of engineering plastics in terms of strength and plastic products, the scope of application is also expanding, and the consumption of plastic products has increased.

It is a plastic product from a plastic mold maker. It consists of several components, this combination is in the mold cavity. The injection molding, the mold is clamped to the injection molding machine, the molten plastic is poured into the mold cavity and cooled in the cavity, then the upper and lower molds are separated from the top of the mold through the top system product, the upper and lower molds leave the mold, and finally the mold is closed for the next injection, the injection process is a whole cycle.

The plastic mold consists of two parts by the moving half and the fixed half, the dynamic moving template is installed on the injection molding machine, and it is fixed on the fixed template installed on the injection molding machine. In the injection mold and the mold closed form gating system and cavity, the mold is moved halfway and fixedly separated to remove the plastic product.

The mold structure may vary due to the plastic, the variety and performance of plastic products, and the structure and model of the injection molding machine, but the basic structure is the same. The mold is mainly composed of gate control system, temperature adjustment system, molded parts and structural parts. Parts of its casting and molding systems are in direct contact with plastic parts, and the plastic and product changes are the most complex in the mold, the largest changes and parts that require machining finishing and the highest precision.

The gate system refers to the part of the plastic runner before the nozzle enters the cavity, including the cold hole, the main road and the door. Molded parts refer to the shape in which a product is formed into various parts, including molds, molds and cavities, cores, molds, and vents.
