Annotation

A characteristic feature of modern industries is the steady growth of mechanization and automation of production processes. The economic and social significance of mechanization is manifested in a wide range of measures aimed at replacing manual labor with machines and mechanisms, the transition to higher levels of mechanization, and ultimately to the highest degree of mechanization of automation.
The combined development of science and technology significantly affects both complex and partial (non-complex) mechanization of production processes, generating an increase in the number of parts. A significant place in the technology of manufacturing parts is the casting process. About half of the parts are made of molten metals and other materials.
One of the common methods is die casting. Shells (molds) of metal or cast iron molds, for free (gravitational) filling with liquid metal, are used repeatedly. Detachable and non-removable (solid) molds are used. The opening surface of the detachable mold can be horizontal, vertical, or combined. The subject of the study is a mold, which consists of two half-shapes with a vertical opening surface and pins of mutual centering of the shells.
A wide range of enterprises: mining and processing plants, cement plants, construction plants, energy generating companies, etc. use the products of casting in the mold grinding layers. All types and sizes of grinding layers are intended for grinding of raw materials.
Due to various technical reasons, during casting, a metal film is formed near the grinding balls, which fills the entire surface of the opening of the detachable mold. The operation of removing the lattice from the grinding layers is necessary to reproduce the geometric shape, quality requirements and considerations of industrial aesthetics of the product. Performing such an additional operation requires the collective work of employees with the use of physical force and appropriate tools. Existing technology with the use of metalwork tools leads to a deterioration in the appearance of the layers, and sometimes to damage the products.
The essence of improving the lattice operation is to use a specially designed device for this operation, which in turn creates the conditions for mechanization of the production of grinding balls.

Keywords: grinding balls, grinding balls, grinding balls, grinding bodies, round, lattice, chill mold, chill casting, free pouring, gravitational pouring.
