Do you understand the structure of plastic molds?

Plastic mold is a tool for consuming plastic products. It is partially composed of several groups of parts, and there is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and is cooled and shaped in the cavity, and then the upper and lower molds are separated, and the product is ejected from the mold cavity through the ejection system to separate the molds. Close to abort the next injection, the entire injection process is cyclically aborted.

Ordinary plastic molds are composed of a movable mold and a fixed mold. The movable mold device is on the movable template of the injection molding machine, and the fixed mold device is on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products.

Although the structure of plastic molds may vary widely due to the type and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the fundamental structure is different. Plastic molds are mainly composed of pouring system, temperature control system, molding parts and structural parts. The pouring system and molded parts are in direct contact with the plastic. And it changes with plastics and products. Is it the part of the plastic mold that is more complicated and changes a lot, and requires higher processing brightness and precision? The gating system refers to the part of the runner before the plastic enters the cavity from the nozzle, including the mainstream Channels, cold slug holes, runners and gates, etc.
