Four-template sand-covering molding machine device and working method thereof

Abstract

The invention relates to a four-template sand-covering molding machine device and a working method thereof, and belongs to machinery. The sand-covering molding machine device comprises a sand shootingand sand covering mechanism, mold closing and stripping mechanisms, a template shuttle mechanism, sand shooting head shuttle mechanisms, an iron type conveying roller way, an upper beam, a stand column, a sand hopper, an air bag and a base, wherein the upper beam is connected with the base through the stand column; the sand hopper and the air bag are arranged on the upper beam; the iron type conveying roller way is arranged on the stand column; the sand shooting and sand covering mechanism is fixed on the upper beam; the sand shooting head shuttle mechanisms are matched with the sand shootingand sand covering mechanism, and are each provided with two sand shooting heads capable of shuttling and moving; lifting cylinders of the two mold closing and stripping mechanisms are fixed on the base; and the template shuttle mechanism is fixedly installed on the base. The invention also provides a working method of the four-template sand-covering molding machine device. The device is simple and reasonable in structural design, safe and reliable, convenient to assemble, disassemble and maintain, small in occupied space, low in production line input cost and capable of meeting use requirements.

Description

technical field [0001] The invention relates to a device and a method, in particular to a four-platen sand-covered molding machine device and its working method, belonging to the field of machinery. Background technique [0002] Iron mold sand-coated casting belongs to special casting, and its mold is formed by covering a thin layer of coated sand on the inner cavity of the metal mold. Iron sand-covered casting has the characteristics of energy saving, material saving, high efficiency, high quality, green production, etc., and its application fields are becoming wider and wider. The cavity of the iron mold sand-covered mold generally uses a sand-covered molding machine to complete the sand-coated molding of the iron mold. [0003] General-purpose sand-covered molding machines include single-station sand-covered molding machines and double-station sand-covered molding machines. Iron mold sand-covered casting is generally suitable for the production of large-scale castings, ...

AI Technical Summary

Problems solved by technology

Although this patent can improve the sand covering quality and sand covering efficiency, and simplifies the structure of the sand covering molding machine; but the layout method not only increases the length of the production line, but also increases the input cost of the auxiliary equipment of the production line, so it still has the above defects
