Lost foam casting wax pattern repairing method

Abstract

The invention relates to a lost foam casting wax pattern repairing method. Lost foam casting wax pattern repairing equipment comprises a bottom plate, an annular frame, a bearing device and a repairing device, wherein the annular frame is arranged at the upper end of the bottom plate, and the bearing device is arranged below the annular frame; and the bearing device is arranged on the bottom plate, the repairing device is arranged behind the annular frame, the repairing device is arranged on the bottom plate, and the lower portion of the front side of the repairing device is connected with theannular frame. The lost foam casting wax pattern repairing method can solve the problems that the working steps of repairing the wax mold are increased and the repairing efficiency of the wax mold isreduced due to the fact that a wax pattern often needs to be recast due to the fact that fixed-point repairing cannot be carried out on defects on the surface of a cylindrical wax pattern when existing equipment is used for repairing the cylindrical wax pattern, and meanwhile, the production cost is increased due to change of the shape of the wax pattern caused by the fact that liquid wax is prone to further heat and melt the original wax pattern due to the too high temperature caused by te fact that the liquid wax cannot be cooled after being injected into the defect positions of the wax pattern.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a method for repairing a lost foam casting wax pattern. Background technique [0002] The wax model is a model used to make castings in lost foam casting. The wax model is generally used to carve the model of the casting with wax. There is also a negative mold obtained by pressing the silicone mold of the metal original mold, and then the silicone mold is injected with wax. Obtain a wax pattern. The wax pattern is mainly used in lost foam casting to coat the surface with mud to form a mud pattern. After the mud pattern is dried, it is put into hot water to melt the internal wax pattern to form a casting model. [0003] At present, the existing equipment usually has the following deficiencies when repairing the cylindrical wax mold: 1. The existing equipment cannot fix the defects on the surface of the cylindrical wax mold at fixed points, and often needs to recast the w...

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot repair the defects on the surface of the cylindrical wax mold at fixed points when repairing the cylindrical wax mold, and often needs to recast the wax mold, thereby increasing the working steps of the wax mold repair, The efficiency of wax mold repair is reduced. At the same time, it cannot be cooled after the liquid wax is injected into the defect of the wax mold. It is easy to appear that the liquid wax will further heat and melt the original wax mold because of the high temperature, resulting in The change of the shape of the wax model increases the production cost and other problems
