Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and more specifically, it relates to a part forming mold for processing automobile cages. Background Technology

[0002] When processing automotive cages, stamping is usually used. The stamping die consists of an upper die base, a lower die base, a punch, a die, and an ejector structure. During processing, the sheet metal is first placed in the die, and the upper die base and punch are pushed downward by a hydraulic cylinder to apply pressure to the sheet metal. The automotive cage is formed by the cooperation of the punch and die.

[0003] For example, CN216729377U discloses a cage extrusion die, including an upper die and a lower die. Both the upper and lower dies have a hollow cylinder at their centers. A pad is fixedly connected to the bottom surface of the lower die, and a hollow T-shaped cylinder is located at the center of the pad. A lower ejector rod is slidably engaged within the hollow T-shaped cylinder. An ejector rod guide sleeve is provided between the upper circumferential side of the lower ejector rod and the inner wall of the hollow cylinder of the lower die. Eight upper ejector rods are evenly spaced and inserted into the circumferential surface of the ejector rod guide sleeve. The bottom surface of the upper ejector rod... Located on the upper end face of the lower ejector rod, a toothed punch is provided inside the hollow cylinder of the upper die. Eight trapezoidal punches are spaced apart at the lower end of the toothed punch. The upper part of the upper ejector rod is inserted between two adjacent trapezoidal punches. A die is provided between the trapezoidal punch at the lower end of the toothed punch and the hollow cylinder of the upper die. This utility model has the following advantages and effects: external force is applied to the lower ejector rod, so that the eight upper ejector rods act evenly on the cage to be processed, which is simple to operate and has a good pressing effect.

[0004] Based on the above, after a period of use, the punch is prone to wear, requiring frequent inspection of the punch surface. This results in a heavy workload for workers and takes a long time, leading to prolonged downtime of the processing equipment and affecting the processing efficiency of automotive cages.
