The punch and guide post pass through the upper die and are fixed on the pressure plate. The side of the stamping block is in contact with an elastic element.

[0009] The universal mold base is provided with a punch sleeve, which covers the punch and allows the punch to slide inside the punch sleeve.

[0010] The universal mold base is provided with a guide sleeve, which is sleeved outside the guide post, and the guide post can slide inside the guide sleeve.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model is mainly composed of two parts: a stamping die and power devices on its left and right sides. The stamping die adopts an independent and detachable structure and is not fixedly connected to the hydraulic cylinder. Therefore, it is very convenient to replace the stamping die. When replacing the product die, the product die can be quickly replaced. The entire module can be replaced simply by removing the two fixing screws at the top to adapt to different product requirements. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Combined with appendix Figures 1 to 3As shown, this embodiment discloses a punching module assembly and fixing mechanism, including a mold base plate 1, a power unit, and a stamping module, which are fixed on the mold base plate 1. The stamping module includes a universal mold base 2, a mold core 3, a punch 4, a stamping block, a guide post 7, and an elastic element. Stamping blocks are arranged on both the left and right sides of the universal mold base 2. A guide post 7 and a punch 4 are arranged on one side of each stamping block, and the other side of the stamping block is in contact with the output end of the power unit. An elastic element is fitted onto the guide post 7, with one end connected to the stamping block and the other end connected to the universal mold base 2. The mold core 3 is fixedly installed on the universal mold base 2, and the punch 4 passes through the universal mold base 2 and connects to the mold core 3. The universal mold base 2 is detachably fixed to the mold base plate 1 by two fasteners, namely fixing screws 13.

[0019] The power unit is a hydraulic cylinder 11. The piston rod 12 of the hydraulic cylinder 11 is in contact with one side of the stamping block. The hydraulic cylinder 11 is fixed on the mold base plate 1.
