A stamping mold for auto parts

Abstract

The invention discloses an automobile component punching forming die, and belongs to the technical field of automobile component punching. The automobile component punching forming die comprises a bottom plate, a first air pump, a male die, a top plate and a female die. The first air pump is connected to the top of the bottom plate, the female die is connected to the top plate, the end, away fromthe bottom plate, of the first air pump is connected with a sliding plate, the male die is connected to the outer wall of the sliding plate, ejector pins are connected to the inner wall of the femaledie, the tops of the ejector pins are connected with a pressing plate, the top of the pressing plate is connected with second air pumps, and the outer wall of each second air pump is connected with agas releasing valve and a one-way valve; and the ends, away from the female die, of the ejector pins penetrate through the second air pumps and are connected with pistons, and the ends, arranged in the female die, of the ejector pins are connected with ejector sheets. Through the arrangement of the second air pumps, it can be guaranteed that the stretching length of the ejector pins in the motionprocess is proper, and the situation that the ejector pins jack the dies to damage is avoided; and cost is reduced, manual drawing is avoided, the labor intensity is lowered, the work efficiency is improved, and repeated operation is convenient.

Description

technical field [0001] The invention relates to the technical field of stamping of auto parts, in particular to a stamping mold for auto parts. Background technique [0002] Stamping forming refers to the application of external force to plates, strips, pipes and profiles by means of presses and molds. The stamping device below applies pressure to the steel through the punch to cause plastic deformation or separation to obtain the desired shape and size. For auto parts, stamping blanks are mainly hot-rolled and cold-rolled steel sheets and strips. [0003] After the stamping is completed, the mold formed after stamping is often pressed tightly in the die. Nowadays, the ejector pin is usually used to eject the mold, but the existing ejector pin is complicated to install, and the jacking of the ejector pin cannot be grasped. When the jacking height is too high, the ejector pin will damage the mold, increase the cost and reduce the efficiency. If the jacking height is too low,...

Problems solved by technology

[0003] After the stamping is completed, the mold formed after stamping is often pressed tightly in the die. Nowadays, the ejector pin is usually used to eject the mold, but the existing ejector pin is complicated to install, and it is impossible to grasp the jacking of the ejector pin. When the jacking height is too high, the ejector pin will damage the mold, increase the cost and reduce the efficiency. If the jacking height is too low, the mold cannot be ejected from the die, and the mold needs to be ejected again, which is very difficult to operate. Inconvenient, reduces work efficiency
