Quick demoulding device for casting

Abstract

The invention discloses a quick demoulding device for casting. The quick demoulding device for casting comprises a concave die and a convex die, a right ejector plate is arranged on the right side ofthe concave die, a notch is formed in the right ejector plate, a screw hole is formed in a right upright column, and the notch is communicated with the screw hole. A stop block is placed in the notch,a screw rod is placed on the right side of the stop block, a fixing plate is fixedly welded to the middles of a left upright column and the right upright column, a connection rod is fixedly welded tothe fixing plate, sleeves A are fixedly welded to the front end and the rear end of the connection rod respectively, and guide rails are sleeved with the sleeves A. The bottom of the left upright column and the bottom of the right upright column are fixedly welded to a bottom plate, and a cam is arranged on the bottom of the bottom plate. According to the quick demoulding device, the concave dieis separated from the convex die under the action of inertia, the separation efficiency is high, and a casting piece between the dies cannot be damaged; the die separation efficiency is greatly improved, the casting piece production pass rate is improved, and the quick demoulding device provides an important significance for improving the production efficiency and yield of an enterprise.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a quick demoulding device for casting. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Under the action of external force, the blank becomes a tool with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, Powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

Problems solved by technology

In the prior art, the separation of small injection molds is usually done by workers using a crowbar to pry the die from the punch. This method can easily cause deformation of the internal casting, which may lead to scrapping of the casting in severe cases.
