Explain the trimming die structure and installation

Beyond the trimming die structure, including the trimming on the mold sleeve and alloy mold, the product of the trimming on the mold inside the center with a hole with the edge of the trimming die, the product of the end of the mold embedded with alloy insert , In the alloy mold and the alloy insert in the middle of the location with a withdrawal bar, the product of the alloy insert head with trimming boss, trimming the outer diameter of the boss is smaller than the diameter of the inner edge of the trimming die. With the above structure, the cutting time can be cut off once, will not pull the tear phenomenon, so the product will not be pulled bending, burr without burrs, improve the product's pass rate and product quality, The cost of the product.

The cutting edge of the blade structure, which can solve the existing trimming die edge trimmed due to the position of the body caused by the deviation of the phenomenon, so as to ensure that the finished product after processing, reduce production costs. Which comprises a trimming die, characterized in that the outer side end of the take-up concave mold is provided with a retaining block on the trimming die, and the forgings are placed on the block when the trimming is carried out.

The installation structure of the trimming die can solve the problem that the upper mold base needs to be installed twice and the installation efficiency is low when the existing trimming die is installed. The present invention also provides a method for installing the trimming die The Which comprises a upper mold base, a trimming punch mold, a trimming die and a lower mold base, and the upper mold base and the lower mold base are guided by a guide post and a guide sleeve, which is characterized in that it further comprises a punch The die and die die are mounted on the upper mold base by a punch fixing plate, and the trimming die is mounted on the trimming die by a die fixing plate, and the trimming punch and the trimming die are passed through the die Gap fit.
