Therefore, the invention provides a casting integral floating plate forming die, which comprises:
the upper die mechanism comprises an upper forming plate, and an upper forming surface is arranged at the bottom of the upper forming plate;
the lower die mechanism comprises a lower die base and an integral floating plate, a mounting base is arranged in the lower die base, a lower forming plate is arranged at the top of the mounting base, the bottom of the integral floating plate is fixedly mounted in the lower die base through a floating piece, the integral floating plate is sleeved on the mounting base, and second forming plates which are symmetrically arranged on two sides of the lower forming plate are arranged on the integral floating plate.
Further, the floating member is a hydraulic buffer.
Furthermore, a plurality of limiting blocks are arranged on one side of the second forming plate, and the limiting blocks are fixedly installed on the integral floating plate.
Further, the structure of stopper is L shape, and the stopper includes dead lever and gag lever post, dead lever one end fixed mounting on integral kickboard, in the recess of other end joint on the second template, gag lever post perpendicular to dead lever.
Furthermore, the end of the limiting rod is provided with an inclined plane.
Furthermore, a waist-shaped hole and a round hole are arranged on the fixing rod.
Furthermore, a plurality of stripping needles penetrate through the second forming plate.
Furthermore, lugs are arranged on four inner side walls of the lower die holder.
According to the integral floating plate forming die for the casting, provided by the invention, a sheet is placed on the lower die mechanism, and when the upper die mechanism and the lower die mechanism are closed, the two sides of the upper forming plate and the second forming plate press the edge of the sheet to be formed; the integral floating plate moves downwards under the extrusion of the upper forming plate, so that the oil buffer below compresses, and the sheet is formed by the center of the upper forming plate and the lower forming plate. According to the invention, the upper floating plate is not arranged on the die, the edge of the sheet is fixed directly through the upper forming plate and the integral floating plate, so that the shaking is not easy to generate, the forming effect is not influenced, and meanwhile, the edge of the sheet is formed through the upper forming plate and the second forming plate. During mould division, the material taking-off needle penetrating the second forming plate pushes the formed sheet away from the second forming plate, so that blanking is facilitated. A plurality of oil pressure buffers are circumferentially arranged below the integral floating plate, so that the phenomenon that the floating plate shakes when moving downwards is avoided.
According to the casting integral floating plate forming die, the edge of the sheet is fixed through the upper forming plate and the integral floating plate, and the positioning effect of the edge of the sheet is guaranteed.
