High-hardness die-casting die steel quenching treatment equipment and method

The invention discloses high-hardness die-casting die steel quenching treatment equipment which comprises a rack, a heating machine arranged at one end of the top of the rack, a heating ring arranged on one side of the heating machine and a quenching pool arranged at the other end of the top of the rack and corresponding to the heating ring. A positioning and feeding mechanism used for positioning and feeding die steel is arranged above the heating ring, the positioning and feeding mechanism comprises a feeding box arranged above the heating ring, and a through hole corresponding to the heating ring is vertically formed in the feeding box in a penetrating mode. According to the quenching treatment equipment for the high-hardness die-casting die steel, an arranged positioning feeding mechanism is composed of a feeding box, a feeding roller, a rotating air cylinder, a two-way air cylinder, a push arm, a displacement plate, a first spring and the like, clamping and automatic downward displacement of the die stee
