Die frame with stripper plate and guide posts

Abstract

The invention relates to a novel die frame with a stripper plate and guide posts and belongs to the field of dies. The die frame comprises a die handle, a convex die fixing plate, guide sleeves, the stripper plate, the guide posts and a concave die fixing plate, and is characterized in that the die handle is arranged on the convex die fixing plate, the guide sleeves are arranged on the convex die fixing plate, and the stripper plate is arranged on the guide posts which are fixed to the concave die fixing plate. When the novel die frame with the stripper plate and the guide posts is applied, the stripper plate is guided by the guide posts of the die frame and does not shift along with deformation of a punching pin, so that the effects that the punching pin is located in the center of a concave die and a die can work for a long time are guaranteed, the precision of the distance between holes is high, and the degree of precision of products is improved.

Description

technical field [0001] The invention relates to a novel stripping plate guide post type mold frame, which belongs to the field of molds. Background technique [0002] At present, in the field of molds, the mold frame is divided into two parts. The upper part with two guide sleeves fixes the punch fixing plate, and the lower part with two guide posts fixes the die. The punch penetrates the stripper plate and the punch is fixed. Rubber is placed between the plate and the stripper plate, and four screws are used to penetrate the upper part with two guide sleeves at the four corners to connect with the stripper plate. The stripper plate is guided by the punch, and the impact is not great when the diameter of the punch is large. If the diameter of the punch is small, for example, the diameter of the punching pin used for punching is 3 mm, the punching pin will be deformed and the punching hole of the die will be damaged and the punching pin will be broken seriously. The first dis...

[0002] At present, in the field of molds, the mold frame is divided into two parts. The upper part with two guide sleeves fixes the punch fixing plate, and the lower part with two guide posts fixes the die. The punch penetrates the stripper plate and the punch is fixed. Rubber is placed between the plate and the stripper plate, and four screws are used to penetrate the upper part with two guide sleeves at the four corners to connect with the stripper plate. The stripper plate is guided by the punch, and the impact is not great when the diameter of the punch is large. If the diameter of the punch is small, for example, the diameter of the punching pin used for punching is 3 mm, the punching pin will be deformed and the punching hole of the die will be damaged and the punching pin will be broken seriously. The first disadvantage is that the mold cannot always work for a long time. Accessories do not meet requirements
