Extrusion-cutting device for vertical thick-wall sprue with high solid phase and semi-solid state

Abstract

The invention discloses an extrusion-cutting device for a vertical thick-wall sprue with a high solid phase and a semi-solid state. The extrusion-cutting device for the vertical thick-wall sprue withthe high solid phase and the semi-solid state comprises an upper die assembly and a lower die assembly, wherein the upper die assembly comprises an upper die plate, a fixed plate connected onto the upper die plate, and a punch head connected onto the fixed plate; the lower die assembly comprises a positioning mechanism for positioning a workpiece to be extrusion-cut, an extrusion-cutting mechanismfor extrusion-cutting a sprue part of a workpiece, and a stripping mechanism; the extrusion-cutting mechanism and the positioning mechanism are connected onto the stripping mechanism; and the upper die assembly downwards acts on the lower die assembly so as to extrusion-cut the sprue of the workpiece. According to the extrusion-cutting device for the vertical thick-wall sprue with the high solidphase and the semi-solid state provided by the invention, compared with an existing sawing machine saw-cutting method, the extrusion-cutting noise is low, the service life of an extrusion-cutting wheel is longer than the service life of a saw blade, and meanwhile, the cost on replacing quick-wear parts is low. The extrusion-cutting device has higher efficiency on extrusion-cutting multiple products at a time compared with saw cutting. Meanwhile, the problem of environment pollution caused by dust produced by saw cutting is further solved.

Description

Technical field [0001] The invention relates to the technical field of high-solid phase semi-solid die casting, in particular to a high-solid phase semi-solid vertical thick-wall gate extrusion device. Background technique [0002] For the existing thick-walled vertical pouring die casting products, the runner removal method adopts a sawing machine to remove. However, the existing similar pouring die casting products have special shapes and thicker feed materials. Conventional extrusion die is too high for the feed inlet, the knife edge is easy to collapse and cannot meet the extrusion needs. Now it is removed by sawing. The sawing machine is prone to noise and metal dust in the sawing process. Big damage. Summary of the invention [0003] The purpose of the present invention is to provide a high-solid semi-solid vertical thick-wall gate extrusion device, which solves the technical problem that the existing vertical thick-wall gate extrusion device cannot meet the extrusion requ...
