Description

Technical Field

[0001] The utility model relates to a lower die frame structure of motor parts and belongs to the technical field of die accessories. Background Art

The upper mold and lower mold of the casting mold of motor parts are respectively installed at the center of the corresponding upper mold frame and lower mold frame. The current lower mold frame is generally a metal structure, which does not have a buffering effect during the closing process of the upper mold and the lower mold. When the upper mold and the lower mold are closed, it is easy to cause a large impact force and generate a large noise pollution. For this reason, we designed a lower mold frame structure for motor parts. Utility Model Content
