Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to a metal stamping mold demoulding device. Background Art

[0002] Metal stamping die demoulding devices are usually designed to help the stamped parts to be smoothly removed from the die to improve production efficiency and protect the life of the die.

[0003] When existing mold demolding devices are used to process metal parts, they often need to cooperate with stamping machines to form metal raw materials. However, due to the large contact area between the metal raw materials and the mold during the stamping process, the general demolding structure often finds it difficult to eject the stamped metal parts from the mold. In addition, in order to prevent the parts from falling from the mold, the demolding device usually only ejects the parts a small distance from the mold during demolding. After that, workers are often required to use tools to demold the parts for a second time, which affects the efficiency of part demolding.

[0004] Therefore, in order to address the problem that the above-mentioned mold demoulding device often has difficulty in efficiently demoulding parts when stamping metal parts, and is not convenient for users to quickly take out the parts, a metal stamping mold demoulding device has been developed. By adding an elastic demoulding structure, a screw-driven lifting structure and a frame-type demoulding structure to the mold demoulding device, the demoulding efficiency of the device in stamping metal parts can be greatly improved, and it is convenient for users to take out the stamped metal parts. Utility Model Content
