Description

Technical Field

[0001] The utility model relates to the field of thick-walled component molds, in particular to an automobile thick-walled component mold. Background Art

[0002] Automobile thick-walled parts molds are molds used to manufacture thick-walled components in automobile parts. These thick-walled components usually include components of the body structure, engine and suspension system. After the injection molding of general automobile thick-walled parts molds is completed, the temperature will be very high, and it is difficult to cool down quickly, which affects the speed of demoulding;

[0003] Currently, coolant is generally injected into the fixed mold of the injection mold to quickly cool the outer wall and dissipate heat, thereby increasing the demoulding speed;

[0004] However, the shapes of the fixed mold and the movable mold of the existing automobile thick-walled parts mold are mostly fixed, so it is difficult to change and adjust the shapes of the movable mold and the fixed mold according to different thick-walled parts production requirements, so it is not flexible enough to use. For this reason, we propose a automobile thick-walled parts mold. Utility Model Content
