The hydraulic pressure type plastic injection shaper is one of them, it mainly has gathers the mold organization, injects the part, the hydraulic transmission and the electricity control system and so on several parts of compositions, but the

7、hydraulic pump, the hydraulic cylinder, each kind of hydraulic valve, the electrical machinery, the electrical part as well as the control measuring appliance are indispensable control part.Three major components of (1) clamping components. It is a molded member installation Die. Mainly by fixed tem

Mainly by the feeding device and barrel, screw, nozzle, top plastic device, the injection of hydraulic cylinders, injection seat and its

(3) hydraulic transmission and electrical control systems installed in the fuselage on the inside and outside the chamber, is the driving force of the injection molding machine and manipulating the control unit. Mainly composed of hydraulic pumps, hy

10、draulic valves, motors, electrical components, and control instruments. SZ-250A type plastic injection molding machine are small injectionmolding machine. Each maximum injection capacity of 250 g. Basis for theplastic injection molding process, injection molding machine hydraulicdrive system should

11、meet the following requirements: (1) the mold clamping hydraulic cylinder having a sufficiently largeclamping force, and its operating speed can be based on the requirementsof the the clamping and Kai mold process varies. In the injection process, the molten plastic is often injected into the cavity

12、 to a high voltage of 4 15 MPa. Thus, the requirements of the mold clamping mechanism having a sufficiently large clamping force, and to ensure that the movable platen and the stationary platen closely bonded. Otherwise, the mold away from the seam will produce the the overflow edges phenomenon of p

13、lastic products. To this end, without making the size of the mold clamping hydraulic cylinder is too large, and the pressure is too high, often using the mechanical linkage force increasing mechanism to achieve the clamping and clamping. In order to shorten the time of air travel, improve productivi

14、ty, clamping hydraulic cylinder should be fast-moving action template. However, in order to prevent damage to the mold and products, avoid machine subject to strong vibration and impact-generated noise, but also consider the buffer of mold opening and closing process. Accordingly, the hydraulic cyli

(2) injection seat overall movement (forward or backward). Forwardwith sufficient thrust to ensure that the nozzle is brought into close contac

(3) the pressure and velocity of injection should be capable of adjustment, in order to meet the raw material, different the article geometry and layout of the mold gate and so the size of the injection force requirements, as well as the requirements of the different products on the injection speed.
