Mold frame for producing multiple complex mold forgings

Abstract

The invention relates to a mold frame for producing multiple complex mold forgings. The mold frame comprises an upper connecting plate and a lower connecting plate; an upper platform and a lower platform are connected into a whole through guide columns and guide sleeves; an upper base plate and an upper base plate are arranged between the upper connecting plate and the upper platform; an upper forming cylinder is installed in an upper forming cylinder groove, and one end of the upper forming cylinder is fixed on an upper movable mold; the upper movable mold sleeves an upper static mold; an ejection cylinder is arranged in the center of the upper base plate, the upper platform and an upper static mold mounting seat, the output end of the ejection cylinder is connected with an ejection rod,four through guide holes are formed in the four corners of the lower platform, a tooth column is arranged in each guide hole, gears are arranged on the side wall of the lower base plate, the gears aremeshed with the gear columns through openings in the side wall of the lower base plate, each gear is installed at the output end of a motor fixed on the side wall of the lower base plate, and the topof the gear columns is fixed at the bottom of the lower movable mold. According to the mold frame, by the bidirectional forming mode, the eddy current and the flow dividing defect existing in the forming process of the complex forgings are eliminated.

Description

technical field [0001] The invention relates to a mold frame for producing various complex die forgings, and belongs to the technical field of complex forging processing devices. Background technique [0002] At present, complex forgings used in domestic aerospace are generally completed by machining of simple forgings. Not only does the entire production cycle become longer, but the mechanical properties of this forging are much worse than those of precision forgings of the same size, so the design requirements of the part can only be achieved by increasing the weight of the forging. Complex forgings refer to forgings with complex geometric features and their distribution, and no obvious symmetrical relationship. Most of these forgings have abrupt cross-section structures such as webs, ribs, and local bosses. They are important types of load-bearing components and are widely used in aerospace and other industrial fields. During the forming process of such forgings, the fl...

Problems solved by technology

[0003] The present invention aims to eliminate the problems of eddy current and shunt defects in the forming process of complex forgings, and provides a mold base for producing various complex forgings. The blank is placed in the mold, and the upper dynamic and static mold cooperates with the hydraulic press to press down to form, so as to achieve the effect of ordinary mold base
