Injection mold capable of conveniently controlling material flow speed

The injection mold comprises a working box, a beating mechanism and an adjusting mechanism, the right side of the working box is fixedly connected with a gear motor, the output end of the gear motor penetrates through the side wall of the working box and is fixedly connected with a cross rod, and the cross rod is symmetrically and fixedly sleeved with two first gears; each first gear is connected with a second gear in a meshed mode. Through cooperative arrangement of a gear motor, a cross rod and a first gear, a second gear can be driven to rotate, the second gear can drive a push rod to move up and down through a connecting rod, a vertical rod and a connecting plate, the push rod can drive a piston plate to move up and down, and therefore cold water in a water tank is sucked into a straight barrel through a water inlet pipe; cold water is injected into the cooling pipe through the water outlet pipe, and heat on the lower mold plate can be taken away when the cold water flows in the cooling pipe, so that the
