[0021] Four quarter-circular chamfered corners with an R of 0.02 mm are designed and processed at the four corners of the guiding pin blade, so that when the paper tape is punched, it plays a certain buffering role for the paper tape when the punched square hole is edge-sealed;

[0022] The existing mold core is a split type, and the design of the square hole of the mold core is a split type, which affects the forming problem of the square hole to a certain extent. Therefore, in this design, the mold core is designed as an integral type to reduce the adverse factors affecting the forming of the square hole due to the mold core;

[0023] From the above two structural design directions of the mold, the forming problem of the perforated square hole is improved;

[0024] A 0.5mm diameter air blowing and cooling channel running from top to bottom is designed on each cutting edge of the square, so that gas can reach the cutting edge of the square from the upper end of the square when punching the paper tape. The gas separates the paper scraps produced by punching from the square, and the gas passing through the square will take away some heat, which has the effect of ventilating and cooling the square and extending its life.
