Description

Technical Field

[0001] The present invention relates to the field of hardware moulds, and in particular to a hardware mould. Background Art

[0002] Hardware molds are generally used in the die-cutting industry, which has the following advantages:

[0003] With high precision, the metal molds can be customized according to customer needs, which can achieve high-precision die-cutting processing and improve the accuracy of finished product size and shape.

[0004] The production cycle is short. Compared with other types of molds, the production cycle of hardware molds is usually shorter, which can quickly meet customer needs.

[0005] Good wear resistance. Hardware molds are generally made of high-hardness metal materials with good wear resistance. They can maintain the sharpness of the die-cutting blades for a long time and improve the efficiency and quality of die-cutting.

[0006] The mold has a long life and the hardware mold is highly durable. After proper maintenance and care, it can be used many times, which increases the life of the mold and reduces the cost of mold replacement.

[0007] However, when using hardware molds to punch products with smaller areas, there is still a large amount of waste of mold templates. At the same time, the life of the mold is fixed, and after a certain number of punching, there will be abnormal punching such as hair. In addition, because the mold cost is expensive, hardware molds are generally not prepared. After a punching abnormality occurs, it is necessary to wait for the mold to be repaired or redone, which prolongs the production time and increases the cost. Summary of the invention

[0008] The purpose of this application is to propose a hardware mold to solve the above problems.

[0009] A hardware mold comprises an upper mold base, the lower end of the upper mold base is fixedly connected to an upper pad, the lower end of the upper pad is fixedly connected to a fixed plate, the lower end of the fixed plate is connected to a stripping plate through a guide column and a spring, a concave mold plate is arranged below the stripping plate, the lower end of the concave mold plate is fixedly connected to a lower pad, the lower end of the lower pad is fixedly connected to a lower mold base, a first punching group for a punch to pass through, and a second punching group are arranged on the fixed plate and the stripping plate, and the punches can be loaded into the first punching group and the second punching group.

[0010] The beneficial effect is that after a punching abnormality occurs in the punch installed in the first punching group, the punch can be reinstalled in the second punching group to continue the punching process, so that the mold does not need to be shut down for maintenance due to the abnormality, reducing the time cost caused by mold maintenance in product production, and ultimately improving the market competitiveness of the product.

[0011] Preferably, at the lower end of the stripping plate, a first pressing block and a second pressing block are respectively fixedly connected on both sides along the product running direction.

[0012] The beneficial effect is that the first pressing block and the second pressing block provide side limiting for the product.

[0013] Preferably, the first punching group includes

[0014] A first punching hole, the first punching hole is located in the inner side of the fixed plate and the stripping plate;

[0015] The first positioning holes are located on both sides of the first punching hole, and the first positioning holes are respectively located on the sides of the first pressing block and the second pressing block.

[0016] The beneficial effect is that a punch can be installed in the first punching hole, and a fastener such as a pin can be installed in the first positioning hole.

[0017] Preferably, the second punching group includes

[0018] A second punching hole, the second punching hole is located in the inner side of the fixed plate and the stripping plate;

[0019] The second positioning holes are located on both sides of the second punching hole, and the second positioning holes are respectively located on the second pressing block and the side edges of the second pressing block.

[0020] The beneficial effect is that a punch can be installed in the second punching hole, and a fastener such as a pin can be installed in the second positioning hole.

[0021] Preferably, the side edges of the first pressing block are respectively provided with a first recess and a second recess around the first positioning hole and the second positioning hole.

[0022] Preferably, the side edges of the second pressing block are respectively provided with a third recess and a fourth recess around the first positioning hole and the second positioning hole.

[0023] Preferably, guide needles are provided on the sides of the first pressing block and the second pressing block, and the guide needles are located on one side of the second positioning hole.

[0024] The beneficial effect is that the guide needle is mainly used to accurately guide the material strip before the mold is made.

[0025] Preferably, there is a gap between the stripper plate and the concave plate for the product to pass through. BRIEF DESCRIPTION OF THE DRAWINGS
