Preparation method of precise casting wax mold repair wax

Abstract

The invention discloses a preparation method of precise casting wax mold repair wax. The preparation method comprises the following steps that a, firstly, selected raw materials are processed; b, auxiliary materials are prepared after the step a is finished; c, after the step b is completed, and then heating and fusing are carried out by utilizing a stirrer; d, after the step c is finished, the preparation of the repair wax is carried out; and e, after the step d is completed, finally the repair wax is collected. According to the preparation method, in the process of manufacturing the repair wax, the auxiliary materials are added on the conventional raw materials, white vaseline, rosin, petrochemical engineering resin and stearic acid in the auxiliary materials are utilized, the overall hardness of the repair wax can be increased according to the proportioned proportion, and the adjusting degree is higher, and therefore, different repairing requirements can be met, and the production cost can be effectively controlled; and cooling equipment can be provided for gradually cooling when mechanical fusion is carried out, so that the formation of internal air holes is avoided on the premise that the adhesion performance is improved, the forming speed and the overall density are increased, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of repair wax, in particular to a method for making repair wax for precision casting wax models. Background technique [0002] With the development and progress of society, precision castings have been widely used in all industrial sectors including aviation and weapons, especially electronics, petroleum, chemical industry, transportation, light industry, textile, pharmaceutical, medical equipment, pump and valve components . Investment precision casting is a casting process with little or no cutting. The castings produced have high dimensional accuracy, low surface roughness, high flexibility and strong adaptability. Especially for parts with complex shapes, this casting is superior. sex is more pronounced. In the investment casting process, the manufacture of the wax pattern is an important link, and the surface quality of the wax pattern determines the surface quality of the casting.

Problems solved by technology

[0003] At present, the repair wax on the market can cooperate with the repair work of the wax model, but in actual use, the long-term use of the wax model mold will inevitably cause surface bumps and wear, so the surface of the wax model needs to be repaired
