First, the definition of the mold

    Mold (mújù), a variety of molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired product. In short, a mold is a tool used to make a shaped article. The tool consists of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Known as the "mother of industry" title.

    Second, the classification of the mold

    Depending on the material being formed

    Hardware molds, plastic molds, and their special molds.

    Hardware molds are divided into: including stamping dies (such as punching dies, bending dies, deep drawing dies, boring die, shrink hole dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, 镦Forging die, etc.), extrusion die, extrusion die, die-casting die, forging die, etc.;

    Non-metal molds are divided into: plastic molds and inorganic non-metal molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds and the like.

    Third, the working principle of the mold

    The two-shot molding mainly produces two-shot products by two moldings of two-shot forming machine and two sets of molds in two steps.

    Working steps: 1. A raw material is injected into the single-shot product into a single-shot product A through the A-tube.

    2. After the cycle is opened, the product A is left in the male mold, and the formed maneuver template is rotated to the B-mold.

    3. The B raw material is injected into the B-tube to form a two-shot finished product, and the mold is ejected.
