Abstract
The utility model discloses an automatic thermostatic heating device of a hot chamber die casting machine nozzle body, which improves a nozzle heating device which uses gas and is arranged on the outer periphery of an existing hot chamber die casting machine nozzle body into a medium frequency induction heater wrapped and fixed by an outside insulating layer. The medium frequency induction heater is composed of a copper pipe, which is sleeved on circumference of the nozzle body and provided a length equal to that of the nozzle body, and a coil curled around the circumference of the copper pipe. After the automatic thermostatic heating device is connected to power, medium frequency current passes through the coil of the medium frequency induction heater on the nozzle body, and vortex current generated in the nozzle body heats molten metal flowing through the nozzle body to a temperature required by die casting. By heating the nozzle body by using the medium frequency, the vortex current in an induction coil generates high temperature heat which uniformly heats the molten metal from inside out and keeps a certain temperature, thereby effectively resolving the problems that the heating way of the existing nozzle body has high energy consumption, low heat efficiency and defective casting formation, and exhausted waste gas results in severe pollution.
