Description

A kind of automotive gearbox back and away from the shell mold

technical field

The utility model relates to the technical field of moulds, in particular to a mold for retracting and separating the casing of an automobile gearbox.

Background technique

Existing automotive gearbox shell molds usually include an upper mold with a cavity and a lower mold with a convex module. When working, the upper mold and the lower mold are combined with each other, and the gap between the cavity and the convex module constitutes the cavity. , the liquid aluminum alloy enters the cavity from the pouring system and then becomes the desired die-casting after cooling. Finally, the die-casting is ejected by the ejector mechanism on the lower die, which completes a molding process.

After the casting process is over, the cooling process is very important. Only when the formed product is cooled and solidified to a certain rigidity, can it avoid deformation due to external force after demoulding. However, the existing mold does not have good heat dissipation performance, and the cooling time is long. Thereby, the efficiency of mold forming will be reduced, and the demoulding of existing mold products is inconvenient.
