A balanced injection structure for a rubber injection
machine, comprising an upright injection
barrel connected to a plasticizing part, with an injection
plunger head in transmission connection with an injection cylinder, a
nozzle body at the lower end, and an injection cylinder with a There are more than two, which are evenly distributed on the side of the injection
barrel, and the
piston rod of the injection cylinder is connected with the transmission
plunger head of the injection cylinder. The injection part of the present invention is placed vertically, but the injection cylinder and the injection
barrel are arranged in a plane and parallel, so that the height of the whole
machine is reduced; the plasticizing part and the injection part are independent, the
temperature control of the plasticizing and injection parts is easy to control, and the
nozzle opening is reduced The amount of
vulcanization of the
rubber material, and the cleaning of the
rubber material is convenient; at the same time, there are more than two injection cylinders, which are evenly distributed on the side of the injection barrel, and the
piston rod is connected to the injection
plunger head of the injection barrel through a beam. When injecting, the
piston rod retracts and pulls the crossbeam; the crossbeam pushes the injection plunger head, and the injection plunger head pushes the rubber to be injected through the inner flow channel of the
nozzle body.
