        Injection molding machine during the installation process, you want to adjust the relevant checking the accuracy of the injection molding machine, in order to meet its performance requirements.
        Most adjustable clamping rail parallelism. Level meter for precision hardened rails on two longitudinal horizontal coarse (lift adjustable horn, so that a level set in the middle of the bubble), the other with a straight edge across the two parallel rails, will be placed on a level parallel straight on foot, as the horizontal level of coarse, medium and large combined calibration signal for the injection molding machine, also applied a level of parallelism injection rail adjustment, and fitted with a clamping device connected to the injection device and positioning pins, tighten their connection bolts and nuts.
        Dynamic testing and adjustment of the template guide post levelness. Carried out in the guide column with precision level meter vertical and horizontal adjustment to the peg, a level first placed horizontally, then vertically positioned, repeated measurements adjusted until it meets the requirement. Also need a ruler across two parallel guide post when measured transversely. Tolerances: horizontal ≤0.16MM / M; longitudinal ≤0.24MM / M.
        Inspection and adjustment of parallelism between the template. Movable platen parallelism and templates plane manufacturing hernia at the factory has been adjusted, tend to be more stable, but due to reasons of transport and installation, it may cause the parameter changes, so after installation to be checked and adjusted, the tuning parameters should be professionals.
        Nozzle and mold positioning adjustment center hole concentricity. Adjustment and mold positioning center nozzle concentricity should be carried out in the template, horizontal and vertical adjustment of the level of the fuselage after. The adjustment method is as follows.
        Loosen the front seat injection guide bar, tighten the screws after the bracket and connected to the fuselage; loosen the injection seat horizontal guide before adjustment on both sides of the bracket lock nut on the bolt.
        With more than 0.05mm precision vernier caliper, respectively, measured along the horizontal diameter and vertical directions L1, L2, L3, L4, pay attention to adjust the horizontal adjustment bolt measurement that L1 = L2; adjust the vertical adjustment screw, so that L3 = L4 . The measurement error is not greater than given in the following table concentricity 1/2.
        When adjusting the nozzle and mold positioning center hole concentricity, due to changes in the injection holder guide bar may produce distorted, causing the gap screw and barrel wear arising shifted, therefore, adjust the nozzle and mold positioning center hole Meanwhile concentricity must also take into account the measurement, adjust seat injection level (with a tolerance value ≤0.05 / M) of the guide bar; the gap with a feeler screw tail and barrel.
        Cooling water piping connection: injection molding machine cooling water pipes generally have three circuits, namely hydraulic oil cooling circuit (connected to the oil cooler), barrel mold cooling circuit and the cooling circuit. Water drawn from the water supply pipe is divided into two, one is connected to the oil cooler, another connection distributor, then it could be connected to a wide barrel and die by the distributor were frugal.
        Injection molding machine installation Other matters:
        1. Install all parts removed during transport. Such as hoppers, storage tank (automatic silo) and the like.
        2. Press the relevant national standards and user requirements to install the power cable, other electrical lines.
        3. all matters relating to the end of the installation, check the steering pump, the specific operation precautions are as follows:
        A. Fill hydraulic oil tank above the standard position. Fill hydraulic tank must be clean, otherwise it should be cleaned.
        B. Turn the power switch.
        C. After using the pump motor switch on the control panel, click jogging pump motor, immediately shut down, although no steering pump view is correct, if the correct wiring should be transferred in the pump motor.
