[0002] Punching dies are a general term for blanking dies, punching dies, cutting dies, notching dies, trimming dies, and slicing dies. Among them, punching dies are dies for punching holes in flat plates. Punching dies are needed in the process of punching holes in plates of automotive parts.

[0003] After the sheet is processed by the punching die, the punched residue will be discharged through the discharge opening and collected in the waste box that falls below the die. When a certain amount of waste is accumulated, the waste box will be taken out and the waste inside will be discharged. After the waste is punched, it falls straight into the waste box under the action of gravity. Since the relative positions of the punch and the punch hole are fixed, the waste cannot be evenly distributed in the waste box after falling into the waste box, which affects the waste box's capacity for waste and causes the waste box to be dumped more frequently.

[0004] Therefore, in order to solve the above problems, a material discharging mechanism based on automobile mold processing is proposed. Utility Model Content
