Description

Technical Field

[0001] This utility model relates to the field of punch press mold technology, specifically a negative pressure suction mold device. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] During the stamping process, the sheet metal is placed on the lower die, and the upper die is pressed down by the hydraulic mechanism to stamp the sheet metal. After stamping, the finished part left on the worktable needs to be removed. However, since the stamped part is relatively flat, it will stick to the worktable, which will affect the operator when manually picking up the part and reduce the stamping efficiency.

[0013] By adopting the above technical solution, the filter screen can be moved by pulling the handle inside the lower mold.

[0014] Preferably, the lower mold also has a rubber ring disposed inside the filter screen, the rubber ring abutting against the mounting groove, the filter screen being located below the negative pressure suction groove, and the filter screen being located above the suction pipe.

[0015] By adopting the above technical solution, the product can be sucked away by a negative pressure suction fan connected to the suction pipe, allowing the product to enter from the negative pressure suction slot and fall into the filter screen.

[0016] Preferably, the lower mold also has a limiting groove formed on the top of the lower mold, the limiting groove being slidably connected to the upper mold punch, and the top of the limiting groove being a stamping cutting edge.

[0017] By adopting the above technical solution, the upper die punch can press the product down into the limiting groove.

[0018] Preferably, the push rod is slidably connected to the limiting groove, and the top of the push rod abuts against the bottom of the upper die punch.

[0019] By adopting the above technical solution, the product located in the limiting groove can be reset on the surface of the lower mold by pushing the push rod upward with a spring.
