The invention discloses a four-sided core pulling structure for a die, which is used for forming a product with buckles at four sides. The structure comprises a male die core, two slider seats and four slider inserts, wherein the core is provided with four insert slots which are on one straight line in pairs, the two straight lines are intersected, male die inserts are arranged at positions where the insert slots are intersected; the two slider seats are respectively arranged on the two opposite sides of the male die core, and first guide chutes are arranged on one sides, close to the male die core, of the slider seats; the four slider inserts are respectively provided with a first block body and a second block body which form an angle, a buckle forming surface is formed on one end, far away from the second block body, of the first block body, the second block body is provided with second guide chutes, the first block body is arranged in the insert slot, and the second guide chutes are matched with the first guide chutes in pairs. The four-sided core pulling structure is simpler, easier to machine, and more convenient to assemble and disassemble.
Description
【Technical field】 [0001] The invention relates to a core-pulling structure, in particular to a four-sided core-pulling structure of a mold. 【Background technique】 [0002] When using molds for product production, sometimes there are undercuts on all four sides of the product. see figure 1 , figure 1 Shown as a product structure. The product 10 has undercuts 11 on all four sides. [0003] Please refer to figure 2 , figure 2 Shown is a four-sided core-pulling structure of a prior art mold. For this type of product 10, the currently adopted method is that the four sides of the product 10 in the mold are provided with slider seats 20, and each of the slider seats 20 is fixed with a slider insert 21, and four slider inserts 21 are surrounded. It is used to form the undercut 11 on all four sides of the product 10. [0004] However, adopting the above-mentioned core-pulling structure requires four slider seats 20 and slider inserts 21 , the structure is complicated, the p...
