Description

TECHNICAL FIELD

[0001] The utility model relates to mould core processing technical field, concretely is a non -spherical surface alloy mould core processing grinding wheel. BACKGROUND

[0002] Mould core refers to the precision part for the key operation of the center part of the mould. Mould core is generally extremely complex in structure, very difficult to process, and very high in cost, and the artificial expenditure for manufacturing often greatly exceeds the material itself. The selection of mould core material is directly related to the cost and service life of the mould. In the mould core processing, tools such as a file, a saw and a grinding wheel are often used for processing.

[0003] A multifunctional grinding wheel piece for non-spherical surface alloy mould core is disclosed in Chinese patent No. CN219504500U, which comprises a mounting sleeve and a grinding wheel piece. An internal thread is formed in the mounting sleeve, and an external thread is formed on the outer side of the mounting sleeve. An installation box is fixedly installed at the bottom of the mounting sleeve. A first motor is fixedly installed on the inner wall at the top of the installation box. The top of the grinding wheel piece is fixedly installed with a second motor. The utility model has the following advantages and effects: the first motor output shaft drives the worm and the worm gear to mesh, thereby driving the rotating shaft to rotate, and the angle of the grinding wheel piece can be adjusted according to the requirements, so that the polished mould core can be chamfered and other work can be carried out. By pulling the U-shaped pull rod, the U-shaped pull rod is moved upward, so that the two ends of the U-shaped pull rod are separated from the grooves at the top of the scraper, thereby the scraper can be taken out, and the debris and other residues on the surface of the grinding wheel piece can be scraped and cleaned.

[0004] The technical scheme of the scheme drives the worm and the worm gear to mesh through the first motor output shaft, thereby driving the rotating shaft to rotate, and the angle of the grinding wheel piece can be adjusted according to the requirements, so that the polished mould core can be chamfered and other work can be carried out, and the application range of the grinding wheel piece can be greatly improved. However, in the actual use process, the second motor is fixedly installed at the top of the grinding wheel piece, the second motor output shaft is fixedly connected with the grinding wheel piece, and the second motor is not convenient to take off from the grinding wheel piece. When the grinding wheel piece needs to be replaced due to serious wear, the grinding wheel piece and the second motor need to be replaced as a whole, thereby causing resource waste.
