Mixed two-color injection molding machine injection molding is the use of plastic plastic thermal physical properties, different colors of plastic raw materials through the funnel into two or more cylinders, the heating coil on the cylinder heating the internal plastic into a molten state, and the cylinder inside the rotating screw, the material in the screw drive action, along the molten state of the material forward transport and compacts. The material slowly begins to plasticize, melt and homogenize under the double action of the shear force of the screw and the external heating. When the screw rotates, the material already in the molten state is pushed to the head of the screw under the shearing force and the friction force of the screw groove. At the same time, under the reaction of the material, the screw moves backward, and the space for storing material is gradually formed in the head of the screw to complete the plasticization process. Then, under the thrust of two or more injection cylinder pistons, two or more screws inject the material from the storage chamber into the mold cavity at high speed and high pressure. After the molten material in the mold is held in pressure, cooled and fixed plasticized, under the action of the mold closing mechanism, the mold is opened, and the ejector device ejector the good products inside, which completes the entire injection molding process. In this process, all are automatically completed, and the mixed two-color injection molding machine completes the molding of mixed plastic products.

(1) Pressure/flow control module (P/Q oil circuit block) Main control system in the entire working cycle, control the oil pressure (P) and flow (Q) in each program system, control the speed and thrust of each actuator size and program. This machine adopts the control circuit of quantitative pump + two-color vertical injection molding machine proportional pressure flow valve, as shown in Figure 17, which is composed of proportional pressure flow valve V1, P, motor MTR, etc.

D2 is the electromagnet, which controls the flow and pressure. When the motor starts, the pump outputs a certain flow. At this time, D1 and D2 have no electrical input, and the pump output flow flows back to the tank through V1 and D2, and the system pressure is zero. D1 and D2 have two-color second-hand injection molding machine electrical signal input, V1 starts to work, part of the oil is set through the proportional valve, V1, D2 and other tubing open, pump output flow through V1, D2 back to the tank. As long as the input value of D1 and D2 electrical signals is changed, the pressure and speed can be adjusted.
