Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die capable of preventing waste materials from clogging it. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material. Stamping moulds are a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping moulds (commonly known as cold stamping moulds). Stamping is a pressure processing method that uses a mould installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the required parts.

[0003] When punching a workpiece, the waste generated after punching will remain inside the punching slot. After a long period of work, the waste will clog the punching slot, which will affect the punching effect and cause incomplete punching of the workpiece. The waste inside the punching slot needs to be cleaned manually, which will delay the punching time of the workpiece and reduce work efficiency.

[0004] Therefore, it is necessary to provide a stamping die that prevents waste from clogging to solve the above technical problems. Utility Model Content

[0034] It should be noted that by providing the connection hole 12 and the connection shaft 15 , the positioning of the lower mold 2 during installation can be achieved, and the convenience of connecting the punching hole 3 and the waste discharge hole 11 can be improved.

[0035] The working principle of a stamping die for preventing waste material clogging provided by the utility model is as follows:

[0036] By setting a waste discharge hole 11 and connecting it to the bottom of the punching hole, when the punching operation is performed, the punching rod 5 moves downward into the punching hole 3 to punch the product and leave the waste generated in the punching process in the punching hole 3. After a period of punching operation, when the waste is accumulated in the punching hole 3, one end of the suction pipe 6 is moved into the waste discharge hole 11, and a negative pressure is generated at one end of the suction pipe 6 by starting the air pump, so that an air flow blowing toward the side of the base 1 is formed in the waste discharge hole 11, and the waste located in the waste discharge hole 11 is discharged from the waste discharge hole 11 or adsorbed by the suction pipe 6. By setting an electric slide rail 10, the electric slide rail 10 can be moved horizontally to move the suction pipe 6 out of the waste discharge hole 11, so as to facilitate the movement of the waste to the waste discharge below, thereby realizing the automatic cleaning operation of the waste, without the need for manual operation, and improving the efficiency.
