Description

Technical Field

[0001] The utility model belongs to the field of automobile door lock stamping dies, in particular to a stamping die for automobile door lock production which is easy to demould. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance.

[0003] According to the Chinese patent with the publication number "CN217393431U", a stamping die for automobile door lock production that is easy to demold is disclosed, including a main stamping mechanism, a pneumatic demolding mechanism and an auxiliary bearing mechanism. The top of the main stamping mechanism is provided with a pneumatic demolding mechanism, and the bottom of the main stamping mechanism is provided with an auxiliary bearing mechanism. The stamping die for automobile door lock production that is easy to demold has a sloped design at the bottom of the top pile, which can evenly spread the downward pressure around the upper stamping plate to achieve a better stamping effect. After the stamping process is completed and before the die plate is driven to rise, the connection port guides the gas transmitted by the external air pump to the micro-pores in the mold core, so that the inner wall of the mold core is filled with gas to generate pressure between the mold core and the component material, helping the parts of the automobile door lock stamping to fall off quickly, realizing an efficient stamping and forming process. The two sets of mold cores provided can facilitate the stamping of two sets of parts at the same time, thereby improving the overall operation efficiency.

[0004] It can be known from the above structure that the above device has micro air holes evenly distributed along the inside of the mold core, so that the connecting port guides the gas transmitted by the external air pump to the micro air holes in the mold core, so that the inner wall of the mold core is filled with gas to generate pressure between the mold core and the component material, which helps the parts of the automobile door lock stamping to fall off quickly, and realizes an efficient stamping and forming process. The material discharge effect is achieved by air pressure, so that when the air pressure is small, it is likely to cause the mold to fail to be ejected, and when the air pressure is high, it is likely to eject the parts and cause the parts to fly around, thereby reducing the practicality of the device. In addition, the upper end equipment has no cooling structure, and the metal parts will generate high heat under instantaneous stamping, which may cause burns when held manually.

After the water reaches the water inlet bin 65, it is sprayed through the atomizing nozzle 66 on the surface of the water inlet bin 65, so that the sprayed water comes into contact with the stamped parts, so that the stamped parts can be cooled down under the action of the water, thereby avoiding scalding when the staff holds the parts. The limiting rod 9 and the limiting hole 8 can limit the mounting plate 4 to avoid the rotation of the mounting plate 4 and the misalignment of the die head 5 and the die groove 11.
