Die-adjusting brake structure of die-casting machine

The utility model relates to a die-casting machine die-adjusting brake structure which comprises a large gear ring cushion block installed on one side of a die-adjusting large gear ring and further comprises an ejection piston and an oil cylinder pipe connector which are installed on the other side of the die-adjusting large gear ring. One end of the oil cylinder pipe joint is communicated with a high-pressure oil pipe, and the other end is communicated with the ejection piston; during working, high-pressure oil is introduced into the oil cylinder pipe joint, and the ejection piston is pushed by the pressure of the high-pressure oil to abut against the mold adjusting large gear ring and interacts with the large gear ring cushion block to limit the action of the mold adjusting large gear ring. The die adjusting brake of the die-casting machine is ingenious in structure, locking force can be effectively guaranteed, the brake function is achieved, the phenomena of die adjusting displacement, tail plate retreatin
