The invention discloses a lower die structure with an automatically-bouncing filter screw plate after punching. The lower die structure comprises a lower die body; a die cavity is arranged in the middle part of the lower die body; and positioning holes are distributed in the lower die body outside the die cavity. The lower die structure is characterized in that three steps are arranged in the die cavity, and are matched with the step surfaces of the filter screw plate to be formed; guiding holes are distributed in the die cavity; the guiding holes are provided with guiding columns; springs are mounted on the guiding columns in a sleeving way; the upper end surfaces of the springs in a normal state are higher than the step surfaces; and a lubricating layer is coated on the internal surface of the die cavity. The die feeding structure with the automatically-bouncing filter screw plate after the punching is reasonable in structural design, and capable of punching for forming once, and materials are easily obtained, so that the labor intensity is low, the time and the force are reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of mold processing, in particular to a lower mold structure that can automatically spring up after a filter screw plate is stamped. Background technique [0002] The filter screw is made by extrusion through a die. The so-called mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] In the filter screw plate forming mold, the existing lower mold has a simple structural design. After stamping and forming, it is troublesome, time-consuming and labor-intensive to take out the material, and the work efficiency is low, which cannot meet the use requirements. Contents of the invention [0004] The purpose of the present invention is to make up for the deficiencies in the prior art, and to provide a low...
