Embodiment Construction

[0016] The following are preferred embodiments of the present invention, but they do not limit the protection scope of the present invention.

[0017] The invention discloses a mirror polishing method for the main body surface of an automobile lampshade forming mold, comprising the following steps,

[0018] Step 1, check the marks left by machining on the surface of the mold body before polishing;

[0019] Step 2: Use oil stone with a particle size of 400-600 and polishing liquid to grind the traces left by the grinding machine. When using oil stone to polish, it needs to be polished with polishing liquid to avoid dry polishing. The main purpose is to prevent heat from the surface of the mold and prevent orange peel. produce. The polishing direction and the trace direction are thrown back and forth at 25°-30°, and then reversed and the trace direction is thrown back and forth at 25°-30° to realize cross-polishing until the traces left by machining can not be seen; here is an ...

Abstract

The invention discloses a mirror polish method of car lampshade forming die body surfaces. The method comprises the steps: the lampshade die body surfaces are processed by sanding rendering, smoothly connecting sand marks of each surface of the lampshade die body, grinding the die body surfaces and cleaning the body surfaces, adopting a gradual mode of rough polishing first and fine polishing to polish, enabling the car lampshade forming die body surface mirrors to achieve the mirror requirements, and providing substantial conditions for improving quality of the lampshades downstream.

Description

technical field [0001] The invention relates to a method for mirror-polishing the surface of a main body of an automobile lampshade forming mold. Background technique [0002] At present, the surface of the main body of the lampshade forming mold in the market generally does not meet the mirror surface requirements, and the specific process is generally sanded by hand with sandpaper steps. In this method, the operator first chooses 180-grit sandpaper for preliminary sanding on the profile, and then selects 240-grit sandpaper for fine sanding, and then uses 360-grit, 600-mesh, and 800-grit sandpaper for sanding step by step, and finally uses 1200-grit sandpaper for finishing. . The surface polished by this method has poor flatness, and the finish still cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for mirror polishing the surface of the main body of the automobile lampsha...
