Problems solved by technology

During the material return process, because the blind hole flange is a molded forging structure, the connection between the blind hole flange and the punch is relatively tight, and the punch is fixedly connected to the punch seat through screws, the punch cannot move, and the piston rod of the jacking cylinder is lifted upwards. Blind hole flanges require a large jacking force, the jacking cylinder is easily damaged, and the service life is short

Abstract

The invention discloses a blind hole flange forming mold material return structure, an upper mold base and a lower mold base, a mold sleeve is arranged on the upper end of the lower mold base, and positioning rings are sequentially arranged in the mold sleeve from bottom to top , a punch seat, a lower blank die and an upper blank die, a limit seat is set between the punch seat and the lower blank die, and a pin is slidably arranged in the limit seat, and the The tail of the pin extends into the lower blanking die and is connected with the punch. A sliding cavity is arranged in the punch seat, and the head of the pin is slidably arranged in the sliding cavity. A jacking cylinder is provided, and the piston rod of the jacking cylinder passes through the lower mold base and is connected with the ejection rod, and the ejection rod passes through the positioning ring, the punch seat, the limit seat and the punching rod in turn from bottom to top. The head is against the blind hole flange arranged in the lower blanking die and the upper blanking die.

Description

technical field [0001] The invention relates to a forming mold equipment, in particular to a material return structure of a blind hole flange forming mold. Background technique [0002] Blind hole flanges are generally formed by die pressing and forging. The mold after the blind hole flange is formed needs to be returned. The original material return structure mainly includes: an upper mold base and a lower mold base. A mold sleeve is arranged on the upper end of the lower mold base. A positioning ring, a punch seat, a lower blanking die and an upper blanking die are sequentially arranged in the die sleeve from bottom to top, and a punch is arranged in the lower blanking die, and the punch The screw is fixedly connected with the punch base, and a jacking cylinder is arranged at the lower end of the lower mold base, and the piston rod of the jacking cylinder passes through the lower mold base, the positioning ring, the punch base and the punch in turn and is arranged on the l...
