High-temperature die-casting oil type mold temperature controller system

The utility model discloses a high-temperature die-casting oil type mold temperature controller system, which is characterized in that through the arrangement of a heat exchanger, when the oil return temperature is higher than a set value, working water in an oil return pipeline can be subjected to heat exchange and cooling through the heat exchanger and then enters the next circulation of the system, so that the normal operation of the system is ensured; through the arrangement of the oil return pressure relief pipeline, when the oil return pressure is higher than a set value, part of return oil is conveyed to the oil tank through the oil return pressure relief pipeline, the pressure is released, and therefore the oil medium pressure in the oil return pipeline is reduced, and normal operation of the system is further guaranteed; an oil tank, a heater and a heat exchanger are sequentially arranged from top to bottom, and a heating cavity of the heater is connected with the top of a heat exchange oil cavity of
