タイトルまたは説明

Prior to injection molding, the movable mold and the fixed mold are closed under the driving of the injection molding machine to form the cavity and the gating system; and the plasticized plastic melt is injected into the cavity by the gating system for cooling solidification, upon cooling solidification, the movable mold and the fixed mold are opened, and plastic parts are ejected by the demolding mechanism.
I. Classification of injection molds
Composition of injection molds
Two major parts:
 
Movable mold (installed on the movable mold plate of the injection molding machine)
 
Fixed mold (installed on the fixed mold plate of the injection molding machine)
 
Prior to injection molding, the movable mold and the fixed mold are closed under the driving of the injection molding machine to form the cavity and the gating system; and the plasticized plastic melt is injected into the cavity by the gating system for cooling solidification, upon cooling solidification, the movable mold and the fixed mold are opened, and plastic parts are ejected by the demolding mechanism.
