Description

Technical Field

[0001] This utility model relates to the field of powder molding manufacturing technology, and more specifically, to a press mold frame structure with separate upper punch guide and mold frame guide. Background Technology

[0002] A powder forming press is a device that presses metal or ceramic powder into a product of a fixed shape (such as a block). Existing powder forming presses generally have an upper punch, a middle die, and a lower punch. Powder forming is completed by the upper and lower punches located above and below the middle die, along with their respective drive devices, closing the mold. However, the mold frame structure of the upper punch currently on the market is usually consistent with the mold frame structure of a powder forming press with a floating middle die disclosed in utility model patent number CN220480245U, such as... Figure 1 As shown, the upper punch plate 32 and the upper punch mounting plate 34 of the upper punch die 3 are directly connected by a guide column 12. In actual production, when the mold is closed, the upper punch drive device 2 moves upward, which will cause the upper punch plate 32 to resonate. The vibration force is easily transmitted to the upper punch mounting plate 34 through the guide column 12, and then to the molded product. This can easily cause defects such as cracks, breaks or deformation in the molded product, ultimately reducing the molding quality and precision of the finished product. Utility Model Content
