Embodiment Construction

[0021] The present invention provides a technical solution: a method for making repair wax for precision casting wax molds, comprising the following steps:

[0022] a. First process the selected raw materials;

[0023] b. Prepare the auxiliary materials after step a is completed;

[0024] c. After step b is completed, use a mixer to heat and fuse;

[0025] d. After step c is completed, prepare the repair wax;

[0026] e. After step d is completed, the repair wax is collected at last.

[0027] In the step a; in the step a; raw materials are low temperature paraffin 52%, polyethylene wax 8%, chlorinated paraffin 18%, talcum powder 5%, silica sol 7%, dimethyl diphenyl sulfide 10% %.

[0028] In the step b: the auxiliary materials are 10-15 parts of white petrolatum, 25-30 parts of rosin, 15-20 parts of petrochemical resin, 8-12 parts of stearic acid, and its size is 120-160 nanometers.

[0029] In said step c: the blender is a vortex stirring mechanism, the fusion process is...

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. [0003] At presen...
