Crosswise-type automatic opening-and-closing mould frame

Abstract

The invention relates to a hot forging process, in particular to a crosswise-type automatic opening-and-closing mould frame capable of saving raw materials and improving the working efficiency. The crosswise-type automatic opening-and-closing mould frame comprises a convex mould punch, a core mould and a pull rod; the convex mould punch comprises an upper convex mould punch, a left convex mould punch and a right convex mould punch; the core mould comprises a first core mould and a second core mould; the upper convex mould punch is fixedly arranged on the upper working panel of equipment through an upper convex mould fixing plate; the left convex mould punch and the right convex mould punch are respectively arranged on a left convex mould fixing oblique plate seat and a right convex mould fixing oblique plate seat correspondingly and fixedly; two octagonal cone cylindrical inner mould sleeves are arranged in cone cylindrical outer mould sleeves and are respectively connected with T-shaped slide ways tightly; the cone cylindrical outer mould sleeves are fixedly arranged on the lower working panel of the equipment; and the lower parts of cone cylindrical inner mould sleeve resetting guide columns are connected with a material jacking support plate on the lower working panel of the equipment in a matching manner. When the crosswise-type automatic opening-and-closing mould frame is used for assembling different moulds, the purposes of extrusion and formation with deep holes, counter bores and holes in a plurality of directions are achieved, no flash is produced, the formation is fast, and the automatic fall-off of a work piece is realized so that the fetching of the work piece is convenient.

Description

technical field [0001] The invention relates to a hot forging process, in particular to an oblique cutting type automatic splitting and closing mold frame suitable for the forging process of multi-directional products with holes. Background technique [0002] At present, the known formwork used for forging products basically continues the traditional open formwork structure with upper and lower separation, and generally belongs to upsetting forging. When the mold base is subjected to the upper and lower forces, because it is not completely closed, some raw materials will overflow, forming overflow edges, resulting in waste of raw materials. After molding, it is necessary to remove the overflow edges and remove burrs. The process is cumbersome; it is easy to stick to the mold, It is inconvenient to take out the workpiece, and the work efficiency is low; due to the poor forming effect, a higher forging ratio cannot be obtained, and it is very difficult to forge multi-direction...
