Abstract
The invention discloses an injection head of a die-casting machine and belongs to the technical field of injection head structures. The injection head of the die-casting machine comprises an injection head body, an injection head connecting rod and an opening type abrasion-resisting ring. The opening type abrasion-resisting ring is arranged at one end of the injection head body. Two sector straight grooves connected with an inner annular groove are formed in the other end of the injection head body. Two sector bosses are arranged on the injection head connecting rod. The sector bosses on the injection head connecting rod are inserted into the sector straight grooves in the injection head body, and after rotating by a proper angle, the sector bosses are arranged in the inner annular groove of the injection head body. Cooling water enters from a water supply pipe, and after strong turbulence is generated through the end of the injection head connecting rod and a cooling channel on an outer cylinder face, the cooling water is discharged from a second water through hole. According to the injection head, the spiral cooling channel is used for generating the strong turbulence, the temperature of the injection head during working is obviously lowered, abrasion resistance and corrosion resistance at high temperature are improved, a structure convenient to replace is used at an easily-abraded or easily-corroded portion, production efficiency is improved, and production cost is lowered.
