The invention discloses injection molding equipment with the high-efficiency cooling rate. The injection molding equipment comprises a feeding opening, an injection mold is installed on the left sideof the feeding opening, a cooling bin is connected to the left side of the injection mold, a water storage bin is fixedly connected to the bottom end of the injection mold, and an injection molding opening is connected to one end of the right side of the injection mold; and a cooling pipe is arranged in the injection molding opening, a liquid bin is connected to the bottom end of the injection molding opening, a sliding groove is formed in the liquid bin, a water inlet pipe is fixedly connected to the interior of the injection molding opening, and a sliding block is fixedly connected to the outer surface of the water inlet pipe. According to the injection molding equipment, a large amount of heat in the equipment is taken away by accelerating circulation of cooling water, meanwhile, the situation of the inconsistent interior is avoided, the circulation path of the cooling water is greatly shortened, the cooling effect of the cooling water is greatly improved, plastic in a melting statecan be separated notably while efficient work is achieved, and the plastic which is not sufficiently molten is sufficiently molten.
