Injection equipment

The invention provides injection equipment and belongs to the technical field of injection molding, the injection equipment comprises an injection oil cylinder, a rotating motor and a screw rod which are sequentially arranged in the injection direction, the injection oil cylinder comprises a cylinder body, a piston rod connected with the screw rod is arranged in the cylinder body, and a wear-resistant belt and a flat key are arranged at the end, connected with the screw rod, of the piston rod; the rotating motor comprises a stator and a rotor which are nested inside and outside, a sliding groove in key groove fit with the flat key is formed in the inner wall of the rotor, the sliding groove penetrates through the two ends of the rotor in the axis direction of the rotor, the moving stroke of the flat key is the overall length of the rotor in the axis direction, and linear movement of a screw is driven through translation of a piston rod. The rotor drives the piston rod and the screw to rotate synchronously. Th
