Problems solved by technology

The above-mentioned sand-covered molding machine is not suitable for sand-covered molding processing of large iron molds. The first reason is that the sand-covered molding mechanism is too large and complicated when used for large iron molds; In other words, it is difficult to maintain consistent sand shooting pressure in each part of the gap between the iron mold and the model when covering sand, and it is difficult to guarantee the quality of sand covering

Abstract

The invention relates to a sand-coating molding device and a method for a large metal mold. The device comprises a supporting frame and a metal mold rollgang. The supporting frame is composed of a lower beam base, columns and an upper beam, wherein a sand coating and shooting device is arranged on the upper beam, a lifting hydraulic cylinder is arranged on the lower beam base, and a lifting working platform is fixed on the lifting hydraulic cylinder. The supporting frame, the sand coating and shooting device, the lifting hydraulic cylinder and the lifting working platform form a sand-coating molding station. The device is characterized in that a lifting mold assembling and drawing device, mold shuttle shifting devices, a metal mold box-delivery device and a mold rollgang are provided, wherein the mold rollgang and the metal mold rollgang are arranged up and down, the mold shuttle shifting devices are fixedly installed on the columns and arranged over two sides of the mold rollgang, the metal mold box-delivery device is fixedly installed on one side of one column and above the metal mold rollgang, and the lifting mold assembling and drawing device is installed on the side of the working platform. The device is compact in structure, small in occupied area and low in production cost.

Description

technical field [0001] The invention relates to a casting equipment and method, in particular to a sand-covered molding device and method for a large iron mold. Background technique [0002] Sand-covered iron casting is one of the special castings. With the development of my country's automobile industry, it is more and more widely used. The core equipment of iron mold sand-covered casting is sand-covered molding machine. At present, there are mainly double-station sand-covered molding machines, which are mainly used for sand-covered molding of iron molds with a plane size within 1500MMX700MM. At present, with the continuous promotion of the application of sand-coated iron molds, more and more products are used, such as: marine crankshafts, exhaust pipes of large engines, cylinder heads, automobile rear axles, etc., the iron mold sand-coated casting of these products , the plane dimensions of the required iron molds often exceed 2000MMX700MM, and some are even above 3500MMX...
