Description

Technical Field

[0001] The utility model relates to a stamping die, in particular to a turnover discharge type stamping die. Background Art

[0002] Stamping refers to a pressure processing method in which a mold installed on a press is used to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] At present, when most stamping dies are used to stamp parts, the parts may be offset during stamping due to insufficient stability, resulting in unqualified parts. In addition, the parts may get stuck in the mold after stamping, resulting in unsuccessful demoulding and the need for manual removal, which will reduce the processing efficiency of the parts. Utility Model Content

[0004] In order to overcome the above shortcomings, the utility model provides a flip-discharging type stamping die, which can stamp parts more stably and demould the parts better, thereby improving processing efficiency.

[0005] The technical solution is: a flip-discharging type stamping die, including a base, an electric push rod, a top plate, an upper die, a moving module, a bracket, a lower die, a rack, a gear, a reset spring, a ejection plate, a fixed plate, a movable ring, a buckle and a clamping spring. Two electric push rods are fixedly connected to the base, a top plate is fixedly connected between the telescopic rods of the two electric push rods, the upper die is fixedly connected to the top plate, the base is fixedly connected to the moving module, the moving module is rotatably connected to the bracket, the lower die is fixedly connected to the bracket, two racks are fixedly connected to the top plate, two gears are fixedly connected to the bracket, the gears are meshed with the racks, the ejection plate is slidably connected in the lower die, two reset springs are connected between the lower die and the ejection plate, the moving module is fixedly connected to the fixed plate, one end of the clamping spring is fixedly connected to the lower die, the other end of the clamping spring is fixedly connected to the movable ring, the movable ring is in contact with the fixed plate, the movable ring is fixedly connected with a buckle, and a clamping groove is provided on the ejection plate.

[0006] As a further preferred solution, a through slot is formed on the lower mold, and the buckle is inserted into the through slot of the lower mold.

[0007] As a further preferred solution, the buckle is provided with an inclined surface, and the buckle is matched with the slot.

[0008] As a further preferred solution, it also includes a die ejection bucket, which is fixedly connected to the base.

[0009] The utility model has the following advantages: 1. The telescopic rod of the electric push rod contracts and drives the rack and the upper mold to move downward. The movement of the rack drives the lower mold and the parts to rotate upward. When the lower mold is swung to a horizontal position, the rack and the gear are disengaged, and the lower mold punches the parts, driving the parts and the ejector plate to move downward, and the ejector plate is engaged with the buckle, so that the part stamping process is more stable and not easy to deviate.

[0010] 2. The telescopic rod of the electric push rod extends to drive the rack and the upper mold to move upward, and the rack drives the lower mold and the parts to rotate downward. When the movable ring squeezes the fixed plate, the ejector plate contacts and locks with the buckle, and the stamped parts are ejected, thereby making the parts better demolded and avoiding the parts from being stuck in the lower mold.
