A casting molding demoulding treatment process

Abstract

The invention relates to a casting molding demoulding treatment process. The casting molding demoulding treatment process adopts the following demoulding device, and the demoulding device includes multiple sets of curved rods arranged crosswise and a hinge that runs through the intersections of multiple groups of curved rods at the same time. The two ends of the shaft and the hinge shaft are provided with triangular brackets, and the curved rod is composed of a horizontal section and an inclined section. The shell breaking mechanism is arranged on the horizontal section, and a round bar runs through the inclined section. The invention utilizes the principle of leverage. When the two groups of round rods approach synchronously, the shell-breaking mechanism installed on the curved rods approaches synchronously. The knocking head on each mounting rod performs multi-directional knocking and breaking on the outer wall of the sand mold, which improves the Casting mold removal efficiency; the invention can adjust the horizontal distance and vertical height of the breaking mechanism according to the actual sand mold size, and can also increase or reduce the number of knocking heads, and can be screwed at the end of the hinge shaft for longer castings A rod, thereby prolonging the length of the hinge shaft, increasing the number of shell breaking mechanisms, and having stronger adaptability.

Description

technical field [0001] The invention relates to the technical field of sand casting demoulding, in particular to a casting molding demoulding treatment process. Background technique [0002] The sand casting process is a casting method in which sand is used as the main molding material to prepare a mold, and it is also the most traditional casting method. Because sand casting is not limited by the shape, size, complexity and alloy type of parts, the production cycle is short and the cost is low, so sand casting is still the most widely used casting method in casting production, especially for single piece or small batch. The basic process of the traditional sand casting process has the following steps: sand preparation, mold making, core making, molding, pouring, sand shakeout, grinding, inspection and other steps. [0003] Among them, after the molten metal is poured into the sand box and solidified, the gate is removed with a hammer and the sand of the casting is shaken o...

Problems solved by technology

However, when knocking off the shell of a casting, for a casting with a long length or a large volume, multiple and multi-directional knocks are required, and a person can only hit one place at a time with a hammer, and the efficiency is low. For this reason, we Provide a casting molding demoulding treatment process
