Analysis of the Thermophysical State of a Heavily Loaded Injection Molding Machine Tool

Improving the performance of heavily loaded metallurgical tools is an urgent production and research problem. The main parameter that determines the quality of a die tool is its durability, depending on the material and the mode of heat treatment. It is known that one of the productive methods for producing complex thin-walled parts from aluminum alloys is the injection molding (LPD) method. Based on the requirements of international standards, the elements of molds of injection molding machines must withstand 25–30 thousand tons. Pressing without loss of mechanical properties and operational durability. The main parameter determining the reliable operation of metallurgical equipment, including matrices and punches of LPD machines, is operability under cyclic loading and thermal exposure, which directly depends on the chemical composition of the material and the method of thermal hardening. The paper presents the results of studies aimed at determining the thermophysical characteristics, since the instrument under study in the form of a punch of an LPD machine operates under conditions of chemical and thermal exposure.
