Abstract

The invention discloses an aluminium-ingot demolding mechanism. The aluminium-ingot demolding mechanism comprises a casting mold and a demolding device, wherein the demolding device comprises a beam frame, hydraulic cylinders and hydraulic pushing rods, wherein the hydraulic cylinders are symmetrically arranged at the two ends of the beam frame; the hydraulic pushing rods are matched with the hydraulic cylinders; the setting positions of the hydraulic pushing rods correspond to those of the top ends of the side walls of the casting mold; the demolding device also comprises conical shafts with grooves at in the large-radius ends; a positioning bosses matched with the grooves at in the large-radius ends of the conical shafts are arranged on the bottom surface in the casting mold; positioning columns are fixed on the beam frame; the lower parts of the positioning columns are detachably connected with the small-radius ends of the conical shafts; and the end parts of the hydraulic pushing rods are also provided with conical bodies contacted withing the casting mold. The aluminium-ingot demolding mechanism disclosed by the invention has a simple the advantages that the structure is simple, the operation is convenient to operate,, the use is safe and reliable in use and low in, the cost is lower, can satisfy the need of the a production line can be fully met, and has wide market prospect as the a technology with high more cost performance for demolding casting demoldings in the technical field of metallurgical machinery has wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of casting demoulding in metallurgical machinery, and mainly relates to an aluminum ingot demoulding mechanism. Background technique [0002] In the process of producing aluminum ingots in the metallurgical industry, the phenomenon of mold jamming or even failure to demould often occurs frequently due to the unsmooth demoulding of the aluminum ingots. Demoulding, which not only increases the labor load and labor intensity of the workers to a large extent, but also greatly reduces the life-span of striking tools and casting molds. At the same time, this demoulding method is likely to cause large axial deformation of the casting, and it is also easy to cause the casting to break due to stress concentration, and even requires repeated casting. This traditional demoulding method has a low qualified rate of products, poor quality, serious waste of resources, and low production efficiency of aluminum ingots, whic...
