Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also varied.
A combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The die is a punch with a variable core composed of a punch combined base plate, a punch assembly, a punch combined clamping plate, a cavity cut-off component and a side cut combination plate. Coordinated change of mold convex, concave mold and auxiliary molding system. A series of plastic parts of different shapes and sizes can be processed. In the plastic processing industry, it is a tool that is matched with plastic molding machines to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also varied.
With the rapid development of the plastics industry and the continuous improvement of the strength of general-purpose and engineering plastics, the application range of plastic products is also expanding, and the consumption of plastic products is also increasing.
A plastic mold is a tool for producing plastic products. It consists of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, then the upper and lower molds are separated, and the product is ejected from the cavity through the ejector system to leave the mold, and finally the mold is closed again For the next injection molding, the entire injection molding process is carried out in a cycle.
Generally, plastic molds are composed of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the fixed mold are separated to take out the plastic product when the mold is opened.
Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature adjustment system, molding parts and structural parts. Among them, the pouring system and molding parts are the parts that are in direct contact with the plastic and change with the plastic and the product. They are the most complex and the most changing parts in the mold, requiring the highest processing finish and precision.
The gating system refers to the part of the runner before the plastic enters the cavity from the nozzle, including the main runner, cold material cavity, runner and gate. Molded parts refer to various parts that make up the shape of the product, including moving molds, fixed molds and cavities, cores, molding rods, and exhaust ports.
my country's plastic molds have formed a huge industrial chain driven by high-tech drives and application needs of pillar industries, from upstream raw and auxiliary materials industries and processing and testing equipment to downstream machinery, automobiles, motorcycles, home appliances, and electronic communications , Construction and building materials and other major application industries, the development of plastic molds is full of vitality.
