Description

Technical Field

[0001] This utility model relates to the field of wax mold repair technology, specifically to a wax mold repair device. Background Technology

[0002] Lost-wax casting is a common casting method. It mainly consists of mold making, wax pattern making, shell pattern making, and subsequent drying, baking, pouring, and solidification processes. The wax pattern is used to form the shape of the casting cavity. To obtain castings with high dimensional accuracy and surface finish, the wax pattern itself should have high dimensional accuracy and surface finish.

[0003] During the wax casting process, air bubbles may be trapped inside the wax during the wax pouring process, resulting in pores that need to be repaired after the wax model is processed. In the existing wax model repair process, a soldering iron is often used to dip into the wax to repair the wax model. However, in actual use, due to the high temperature of the soldering iron, the soldering iron will come into direct contact with the wax model during the wax repair process, which will cause the missing area of ​​the wax model to expand and increase the difficulty of wax model repair. Therefore, a wax model repair device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a wax model repair device to address the problem that, during the process of using a soldering iron to apply wax liquid to repair a wax model, the soldering iron comes into direct contact with the wax model, which causes the missing area of ​​the wax model to expand and increases the difficulty of wax model repair.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
