Description

Technical Field

[0002] The exhaust muffler of a car is the main component of driving noise. The exhaust muffler is a device designed to reduce exhaust noise. The function of the exhaust muffler is to eliminate noise by reducing and attenuating the pulsation of exhaust pressure. The exhaust muffler is produced by a stamping die that uses a production process to stamp metal materials. The usual processing die drives the punch to move up and down, and stamps the muffler with the die. The punch is prone to shaking when moving, causing deviations when the punch contacts the die during the lifting and moving.

[0003] For example, the Chinese patent: "CN220679197U" discloses the following technical solution: a processing mold for an exhaust pipe muffler is disclosed, including a base and a mounting assembly; the mounting assembly includes a die, a punch, a push rod, a top plate, a mounting frame, a frame body, a driving component and a lifting component, the die is fixedly mounted on one side of the base, the top plate is slidably mounted on the side of the die away from the base, the push rod is slidably connected to the base and fixedly connected to the top plate, the mounting frame is fixedly mounted on the side of the base away from the die, the lifting component is arranged on the mounting frame and connected to the push rod, the frame body is fixedly mounted on the side of the base close to the die, the driving component is arranged on the frame body, and the die is connected to the driving component, so that the staff can easily take the muffler out of the die, thereby realizing that the staff can easily take the muffler.

[0004] However, in actual use, if the mold processing force is too large, it will be difficult to eject and it may be difficult to remove the processed muffler, so an auxiliary structure is required for demolding. Utility Model Content
