Problems solved by technology

[0002] Due to the large contact area with the mold and the small thickness of the workpiece during the mold opening process, thin-walled workpieces are prone to defects such as fracture and flash
The existing air pin ejection mechanism is easy to cause damage to thin-walled workpieces during the action process, and it is not suitable for direct large-scale mold opening of thin-walled workpieces. Therefore, a mold for producing thin-walled workpieces is urgently needed to solve the problem. existing technical issues

Abstract

The air channel structure comprises an upper die and a lower die which are matched with each other, a plurality of first air pins are evenly arranged on the top wall, making contact with a workpiece, of the upper die, a plurality of air injection holes are evenly formed in the side wall, making contact with the workpiece, of the upper die, and a second air pin is arranged in the center of the bottom, making contact with the workpiece, of the lower die. And a plurality of third air pins are annularly distributed on the outer side of the second air pin, the upper die and the lower die are connected with air inlet pipes correspondingly, and the air inlet pipes communicate with the first air pin, the air spraying holes, the second air pin and the third air pins correspondingly. The defects in the prior art can be overcome, and the production yield of the thin-wall workpiece is increased.

Description

technical field [0001] The invention relates to a mold, in particular to an air channel structure of a thin-walled workpiece mold. Background technique [0002] Due to the large contact area with the mold and the small thickness of the workpiece during the mold opening process, the thin-walled workpiece is prone to defects such as breakage and flash. The existing air pin ejection mechanism is easy to damage thin-walled workpieces during the action process, and is not suitable for direct large-area mold opening of thin-walled workpieces. Therefore, a mold for producing thin-walled workpieces is urgently needed to solve the problem. Existing technical issues. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an air channel structure of a thin-wall workpiece mold, which can solve the deficiencies of the prior art and improve the production yield of the thin-wall workpiece. [0004] In order to solve the above technic...
