Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to a precision mold frame for a hot punch press. Background Art

[0002] A punch press die frame is a device used to support and fix a mold. The existing punch press die frame mainly includes an upper die frame, a lower die frame and a guide mechanism. The guide mechanism is composed of a guide pin and a positioning guide sleeve. Due to the mutual friction between the guide pin and the positioning guide sleeve, the gap between the positioning guide pin and the positioning guide sleeve gradually expands, causing the movable mold and the fixed mold to be easily misaligned when the mold is used. The existing technology handles this problem by regularly maintaining and replacing the positioning guide pins. However, replacing or maintaining the positioning guide pins will increase production costs. At the same time, after the external temperature changes, the existing guide mechanism is prone to thermal expansion and contraction, resulting in the gap between the positioning guide pin and the positioning guide sleeve being too large or too small, which will also affect the precision of the mold.
