        1、 Plastic mold structure is divided by function
        It is mainly composed of gating system, temperature regulating system, forming part system, exhaust system, guiding system, ejection system, etc. Among them, the gating system and molding parts are the parts in direct contact with plastics and change with plastics and products. They are the most complex and changing parts in the plastic mold, which require the highest machining finish and precision.
        1. Gating system:
        It refers to the part of the flow channel before the plastic enters the cavity from the nozzle, including the main flow channel, cold material cavity, shunt channel and gate, etc.
        2. Formed part system:
        It refers to the combination of various parts constituting the shape of the product, including moving die, fixed die, cavity (concave die), core (punch), forming rod, etc. The core forms the inner surface of the product, and the cavity (die) forms the outer surface shape of the product. After clamping, the core and cavity form the cavity of the die. According to the process and manufacturing requirements, sometimes the core and die are combined by several blocks, sometimes as a whole, and inserts are only used in the parts that are easy to be damaged and difficult to process.
        3. Temperature regulating system:
        In order to meet the requirements of injection process for mold temperature, a temperature regulating system is needed to adjust the mold temperature. For injection molds for thermoplastics, the cooling system is mainly designed to cool the mold (or heat the mold). The common method of mold cooling is to set up a cooling water channel in the mold, and use the circulating cooling water to take away the heat of the mold; In addition to using cooling water to heat hot water or hot oil, electric heating elements can also be installed in and around the mold.
        4. Exhaust system:
        It is set up to exclude the air in the medium-sized cavity and the gas generated by plastic melting from the mold in the injection molding process. When the exhaust is not smooth, the product surface will form gas marks (gas lines), charring and other defects; The exhaust system of plastic mold is usually a grooved air outlet opened in the mold to discharge the air in the original mold cavity and the gas brought in by molten material.
