Problems solved by technology

[0007] Among them, the surface of the 46# grinding wheel is repaired and leveled with a grinding tool inlaid with diamond before use. The surface of the grinding wheel is uneven after many grinding processes. The difference in the degree of unevenness is too large, resulting in different cutting amounts on the surface of different parts of the polished mold workpiece. Phenomena such as excessive roughness

specific Embodiment 3

[0037] A grinding machine processing technology for improving the surface finish of a mold, the specific steps are as follows:

[0038] Rough grinding of the mold workpiece: Grind the rough molded mold with the grinding wheel of the grinder, and reserve a margin of 0.04mm for the workpiece.

[0039] Semi-finishing of mold workpiece: Use 46# grinding wheel to semi-finish the surface of the mold after rough grinding. The speed of 46# grinding wheel is 3000r / min, and the cutting amount is 0.01mm until the workpiece surface has a margin of 0.01mm ;

[0040] Among them, the surface of the 46# grinding wheel is repaired and leveled with a grinding tool inlaid with diamond before use. The surface of the grinding wheel is uneven after many grinding processes. The difference in the degree of unevenness is too large, resulting in different cutting amounts on the surface of different parts of the polished mold workpiece. Roughness is too large and so on. In the semi-finishing process, ...

Abstract

The invention relates to a grinder processing technology improving the surface finish of a die. The technology particularly comprises the following steps of die workpiece coarse grinding, die workpiece semi-finish machining and die workpiece finish machining, the surfaces of a 46 # grinding wheel and a 220 # grinding wheel which are used for semi-finish machining and finish machining are subjected to polishing finishing, and then the grinding wheels are used; the surface of the 220 # grinding wheel obtained after finishing is smeared with abrasive, gaps between air holes formed in the surfaces of the grinding wheels and a grinding material are filled with the abrasive, the grinding cutting edge of the grinding material is weakened, the polishing effect of the grinding wheels on the surface of a die workpiece is improved, and the surface finish of the die workpiece meets the expected requirements; meanwhile, manual polishing operation is omitted, the grinding and polishing steps are reduced, and the finished product rate is increased.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a grinding machine processing technology for improving the surface finish of a mold. Background technique [0002] A mold is a cavity tool with a certain shape and size. It is used in conjunction with various systems or auxiliary mechanisms in the mold to fill various high-temperature liquids or solids (plastic or metal alloy) into the cavity of the mold to produce Industrial parts with specific shape, size, function and quality. Widely used in products in the fields of electronics, automobiles, motors, instruments, electrical appliances, meters, home appliances and communications, 60% to 80% of the parts must be formed by molds. The surface finish during mold processing is usually required to reach Ra0.4. In the traditional grinding machine processing technology, the grinding machine is often used to grind for many times until the surface is reserved with a margin of 0...
