Problems solved by technology

Coatings not only affect the vaporization and gas migration of foamed plastics, but also are closely related to the surface quality, surface defects, casting precision and even the internal quality of castings. However, many existing coatings have high temperature resistance Poor cracking, poor yield and other problems, which in turn affect the quality characteristics of castings

Abstract

The invention discloses a mold treatment method for improving the casting quality of a vibration damper. The method is specifically used for treating a foamed plastic pattern in a mold during evaporative pattern casting. The method comprises the following steps of (1) coating painting, (2) coating drying treatment, (3) reinforcement treatment, and (4) secondary drying treatment. According to the mold treatment method, an existing mold treatment method is specially improved and optimized. The qualities such as the surface precision of castings are effectively improved. The service life of the mold is prolonged. A new thought is provided for development of an existing casting industry technology. The method has good application and popularization values.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a mold processing method for improving the casting quality of an anti-vibration hammer. Background technique [0002] The anti-vibration hammer is designed to reduce the vibration of the wire caused by the wind. The pole position of the high-voltage overhead line is relatively high, and the span is relatively large. When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working conditions are the most unfavorable where the conductor is suspended. Due to multiple vibrations, the wire will be fatigued and damaged due to periodic bending. When the span of the overhead line is greater than 120 meters, an anti-vibration hammer is generally used for anti-vibration. The hammer heads of anti-vibration hammers are mostly gray iron castings, which are made by casting process. In order to improve the quality of casting, most of the hammer ...
