Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a surface treatment process of silica sol wax molds for valve castings, which can solve the problem of removing residues due to faster heat dissipation during manual wiping, but the thermalization temperature is higher. Manual wiping, difficult to remove quickly, may cause burns during the wiping process, and hold a hair dryer to heat the wax model, it is difficult to determine the distance between the two, prone to insufficient or high temperature, it needs to be polished When the surface is heated, it is difficult to move, and it is necessary to wait for the wax model to cool down and harden naturally before polishing.

Abstract

The invention provides a surface treatment process for a silica sol wax pattern of a valve casting. Working is completed by a base, a movable frame, a location bolt, a wrapping device, a circular ringgroup, a dual-purpose device, a cleaning device and an erection ring in a matching manner. The surface treatment process for the silica sol wax pattern of the valve casting is capable of solving theproblems that during manual wiping, residues need to be rapidly removed due to a high heat dissipation speed, however, rapid removal is difficultly realized by the manual wiping due to a high thermalization temperature, the case of scald possibly occurs in a wiping process, a distance between an electric drier and the wax pattern is difficultly determined when the wax pattern is heated by holdingthe electric drier with a hand, so that the case of a too low temperature or a too high temperature easily occurs, and when the wax pattern needs to be polished, the surface of the wax pattern is in athermalized state and difficultly moved, and polishing can only be carried out when the wax pattern is naturally cooled and hardened.

Description

technical field [0001] The invention relates to the field of surface treatment of castings, in particular to a process for surface treatment of silica sol wax molds of valve castings. Background technique [0002] The emergence of silica sol wax molds is mainly to solve the production of some products with complex structures, and the accuracy of the wax molds directly affects the accuracy of the products. After most wax molds are produced, there will be many particle residues on the surface. Traditional The removal method is that people use a hair dryer to heat the part with particles, and then wipe off the particle residue with a soft cloth. [0003] 1. Due to the fast heat dissipation, the residue needs to be removed quickly. However, the heating temperature is high, and it is difficult to remove it quickly by manual wiping. During the wiping process, burns may occur, and the wax mold is touched with a hair dryer. Heating, it is difficult to determine the distance between...
