In addition, the tip size of the cutting punch is large, generally a straight blade head of 0.1mm, and the cutting effect is poor. After each cutting, a small tail of residual glue will be generated, which affects the appearance and yield of the product. Utility Model Content

[0005] The fixing plate is provided with a rubber cutting punch, and the lower part of the rubber cutting punch is provided with two rubber cutting heads, and the incisions of the rubber cutting heads are arc-shaped.

[0006] In the above technical solution, the fixed plate is provided with six cutting knife grooves, the rubber cutting punch is fixedly connected in the cutting knife grooves, and the unloading plate is provided with cutting knife openings corresponding to the positions of the rubber cutting punches.

[0007] In the above technical solution, the cutting die is fixedly connected to the lower die plate.

[0008] In the above technical solution, eight limiting columns are provided on the upper template, and the limiting columns are arranged in two rows on both sides of the rubber cutting groove.

[0009] In the above technical solution, the limiting columns on both sides are square cone columns, and the four limiting columns in the middle are circular cone columns.

[0010] In the above technical solution, the upper mold plate, the fixing plate, the unloading plate and the cutting die are all provided with mounting holes on both sides of the rubber cutting position.

[0011] In the above technical solution, the size of the rubber cutting head is 0.03 mm.

[0012] To sum up, the technical solution of the utility model has the following beneficial effects compared with traditional technical means: the utility model is used for the secondary degumming of alloy resistors in the degumming process, and the limit pin in the prior art is replaced by a limit column structure, which can be more convenient for positioning and installation, and the positioning is more precise. At the same time, improvements are made to the degumming punch of the fixed plate, and the cutting head is changed to an arc shape with a smaller cutting surface, which can directly cut off the glue path without producing a small tail of glue residue, thereby greatly improving the product appearance yield.
