Embodiment Construction

[0010] Such as figure 1 As shown, a guide post mold of a stamping die includes an upper die base, a lower die base 1, four guide posts and four guide sleeves, and the four guide posts are divided into two guide posts 2 on the left side and two guide posts 2 on the right side. Guide post 3, the four guide sleeves are divided into two guide sleeves on the left and two guide sleeves on the right. The distance between the two guide posts on the left is greater than the distance between the two guide posts on the right. The spacing of the sleeves is greater than the spacing of the two guide sleeves on the right.

[0011] In order to further improve the guiding precision, the radii of the two guide posts on the left are greater than those of the two guide posts on the right, and correspondingly, the radii of the two guide sleeves on the left are greater than the radii of the two guide sleeves on the right.

Abstract

The invention provides a guide post mold for a punching mold. The guide post mold comprises an upper mold seat, a lower mold seat, four guide posts and four guide sleeves, wherein the four guide posts comprise two guide posts arranged at the left side and two guide posts arranged at the right side, the four guide sleeves comprise two guide sleeve arranged at the left side and two guide sleeves arranged at the right side, the gap between the two guide posts arranged at the left side is greater than the gap between the two guide posts arranged at the right side, and correspondingly, the gap between the two guide sleeves arranged at the left side is greater than the gap between the two guide sleeves arranged at the right side. The arrangement position of a guide mechanism of the guide mold is regulated, the guide precision is improved, the convolution precision of the upper mold seat and the lower mold seat is ensured, and the quality of a round punching element is improved.

Description

technical field [0001] The invention relates to a guide post die of a stamping die. Background technique [0002] The guide post die is a die guided by a guide post and a guide sleeve between the upper die base and the lower die base. The memetic structure of the guide post is simple, the guiding performance is stable and reliable, and it has high precision, so it is widely used in the field of stamping technology. The most commonly used guide post mold is a guide post mold with four guide posts and guide sleeves. However, when the guide pillar die is used to stamp circular special parts, it is easy to produce deviations in the alignment of the upper die base and the lower die base, and the accuracy and quality of the parts cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a guide post die for a stamping die. [0004] In order to solve the problems of the technologies described above, the t...
