The invention discloses a three-procedure tool for an elastic bar. The tool comprises an upper mold plate and a lower mold plate, wherein an upper mold frame is arranged on the upper mold plate, and left and right edge limb pressing blocks, left and right upper molds and a middle-upper mold are arranged on the upper mold frame; a front lower mold base and a rear lower mold base are arranged on the lower mold plate, a floating plate is arranged between the front lower mold base and the rear lower mold base, and a middle cushion block and side limb cushion blocks are arranged on the floating plate; an edge limb base is arranged at the front end of the rear lower mold base, edge limb lower molds and elastic range cushion blocks are arranged on the edge limb base, and two rear lower mold rollers are arranged on the rear lower mold base; a tail support seat is fixed at the front end of the front lower mold base, a tail support block is arranged on the tail support seat, and a front lower mold roller is arranged on the front lower mold base. Compared with the prior art, the three-procedure tool has the positive effects as follows: the problems about negative angle forming of the tail part of an SKL12 elastic bar, size stability of a product after forming and separation of the product from an upper mold after forming can be well solved.
Description
technical field [0001] The invention relates to a spring bar three-sequence tooling. Background technique [0002] Since the tail of the existing clip has no negative angle design, and the tail of the SKL12 clip has a negative angle requirement, it is determined that the existing clip tooling cannot meet the production requirements of the SKL12 clip. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a three-sequence tooling for SKL12 elastic clips, which can well solve the negative angle forming of the tail of the SKL12 elastic clip, the stable size of the product after molding, and the stability of the product from the upper mold after molding. Shedding problem. [0004] The technical solution adopted by the present invention to solve the technical problem is: a spring three-sequence tooling, including an upper formwork and a lower formwork, an upper formwork is arranged on the upper ...
