The invention discloses a step tubular beam support forming mold. The forming mold comprises an upper mold body, a lower mold body, a mold core and a pressing plate, the upper mold body and the lowermold body are oppositely arranged, a pressing mold body protruding downwards is arranged at the bottom of the upper mold body, the shape of the bottom of the pressing mold body is matched with the shape of the inner side of a step tubular beam support, a groove corresponding to the pressing mold body is formed in the top of the lower mold body, the pressing plate capable of sliding up and down onthe side wall of the groove is arranged in the groove, the shape of the top of the pressing plate is matched with the shape of the outer side of the step tubular beam support, the mold core is arranged in the center of the bottom of the groove, a through hole allowing the top of the mold core to penetrate upwards is formed in the center of the pressing plate, the mold core is in sliding fit with the through hole, the shape of the top of the mold core is matched with the shape of the outer side of a rectangular hole in the middle of the step tubular beam support, and a groove position corresponding to the top of the mold core is formed in the center of the bottom of the pressing mold body.
Description
technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a molding die for a stepping pipe beam support. Background technique [0002] like figure 1 As shown, it is a stepping tube beam support that needs to be processed. It is produced by 510L beam plate. Since the stepping tube beam support is thick and has many flanges, especially the arc transition part, if the mold design is unreasonable , can easily cause cracking or rebound. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a mold for forming the stepping pipe beam bracket. [0004] The technical scheme adopted in the present invention is: [0005] A molding die for a stepping pipe beam support, comprising an upper die, a lower die, a mold core and a binder plate, the upper die and the lower die are arranged oppositely, and the bottom of the upper die is provided with a downwardly protruding pr...
