[0023] like Figure 1-8 As shown, the present invention solves the problems that the existing left and right side plate stamping forming dies of seats are difficult to position and clamp, and are easy to loosen during the forming process, and provides the following technical solutions: a side tooth extraction forming die for the left and right side plates of a seat, comprising a stamping upper die 4 and two stamping lower die stations 3 installed on the upper side of a workbench 2, the stamping upper die 4 is installed on a punching head 1, the stamping lower die station 3 comprises a product positioning forming die 7 located in the middle and a left forming die 5 and a right forming die 17 respectively installed on both sides of the product positioning forming die 7, the left forming die 5 and the right forming die 17 are driven by a plurality of oil cylinders 13 installed on the lower side of the workbench 2 to translate inward or outward, and the upper part of the left forming die 5 faces the product positioning forming die 7. A side pressure plate 10 is installed on one side of the product positioning molding die 7, and the side pressure plate 10 is connected to multiple side push cylinders 11 inside the left molding die 5. A side tooth extraction block 12 is embedded in one end of the left molding die 5. A matching positioning groove is provided at the side of the product positioning molding die 7 corresponding to the side tooth extraction block 12. By arranging the left molding die 5 and the right molding die 17, the product on the product positioning molding die 7 can be clamped, and at the same time, when the stamping upper die 4 is pressed down, it is formed together with the side pressure plate 10. By arranging the side tooth extraction block 12, the product can be positioned through the tooth hole at the end of the product, thereby improving the accuracy and stability of product positioning and ensuring the accuracy of stamping.

[0024] Specifically, the workbench 2 and the punch head 1 are structures of existing conventional punching machines or molding machines. The two stamping lower die stations 3 are symmetrically arranged with respect to the center of the workbench 2. When in use, the left forming die 5 and the right forming die 17 are translated outwardly under the action of the oil cylinder 13, and the side tooth extraction block 12 is disengaged from the positioning groove on the product positioning forming die 7, and then the product is placed on the product positioning forming die 7 on the two stamping lower die stations 3, and then the left forming die 5 and the right forming die 17 are translated inwardly under the action of the oil cylinder 13 to clamp the side of the product, and the side tooth extraction block 12 is inserted into the positioning groove through the tooth hole on the product to position the product.
