[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model provides a kind of side punching continuous die, realize the continuous punching of both sides of part, Figure 1 Specific structure as shown in Figures 2-6 It includes upper die 1 and lower die 2 oppositely arranged, and guide column assembly 3 arranged between upper die and lower die, the upper die includes upper cover plate 11, upper clamping plate 12, limiting frame 13 and sliding type upper mold core 14 from top to bottom in sequence, and the sliding type upper mold core is symmetrically arranged first mold core and second mold core, and first mold core and second mold core can be away from each other or close to each other, a plurality of punches 15 (three groups are preferred in the embodiment) are assembled on the bottom surface of first mold core and second mold core, and the side surface of punch is provided with protrusion 16 for realizing side punching of part;Lower die includes bottom plate 21, pad block 22, lower pad plate 23, floating plate 24 and lower mold core 25 from bottom to top in sequence, wherein lower mold core is fixed on floating plate, and a plurality of part grooves 26 for placing parts are arranged on the surface of lower mold core, and part groove is one-to-one corresponding with punch of upper die, triangular wedge block 27 passes through floating plate and is arranged on lower pad plate, with the descending of upper die, punch is inserted into the part below, and triangular wedge block is inserted between first mold core and second mold core, so that first mold core and second mold core are opened, and punch moves horizontally so that the protrusion on the side surface of punch punches the side surface of part.

[0027] Specifically, the limiting frame is fixed on the back of the lower clamping plate, a plurality of punches are located in the limiting frame, the limiting frame limits the outward expansion distance of the punch, and the side of the limiting frame is provided with a penetrating opening 131 opposite to the triangular wedge, so that the triangular wedge is inserted when the upper die and the lower die are closed.
