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

Abstract

The invention relates to a method for repairing wax molds of lost foam casting, which comprises a bottom plate, a ring frame, a holding device and a repairing device. A ring frame is installed on the top of the bottom plate, and a holding device is arranged below the ring frame. The holding device is installed on the bottom plate. A repairing device is arranged at the rear of the ring frame, the repairing device is installed on the base plate, and the lower part of the front side of the repairing device is connected with the ring frame. 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 mold increases problems such as production costs.

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...
