Description

Technical Field

[0001] The utility model relates to the technical field of photosensitive resin processing, in particular to an ultrasonic bubble cleaning device applied to a photosensitive resin wax mold shell. Background Art

[0002] The existing photosensitive resin wax mold shell will have residual ash after baking, and the ash will adhere to the surface of the shell in the form of white powder particles. The residual ash of the photosensitive resin is inorganic. When pouring molten metal, the temperature of the molten metal can reach above 1200℃. The high temperature will gasify the ash to form small bubbles, and then form pitting on the surface after the metal cools and solidifies. Some of the ash that cannot be completely gasified will become impurities inside the metal, affecting the quality of the parts.

[0003] Therefore, the ash needs to be removed to avoid affecting the quality of the parts. However, the current method of cleaning the photosensitive resin wax mold shell after baking is generally to inject high-pressure air into the mold shell, blow the ash to float, and then pour it out by inversion; or to inject a solvent (such as clean water) into the mold shell, shake it, pour out the clean water, and pour out the ash mixed with the solvent along with the solvent. However, high-pressure air is only suitable for mold shells with simple structures. Due to aerodynamic problems, high-pressure air cannot blow the ash in deep layers and narrow locations of mold shells with complex structures. Since the ash is mostly micron-scale dust, it is easy to agglomerate after meeting the solvent. If it adheres to the surface of the mold shell, it is more difficult to clean. Therefore, we propose an ultrasonic bubble cleaning device for photosensitive resin wax mold shells. Utility Model Content
