Safety requirements for injection molding machine processing and hydraulic devices

    1. Injection molded rubber protective devices are required on the back plate of the die base to avoid hurting the surrounding people when ejecting the ejecta from the outlet.

    2. The glass window of the safety door shall not be damaged. Prevent the melt from flying away from the cavity and scalding.

    3. The hydraulic system requires a filter.

    4. The inner wall of the storage tank must be protected against external pollution and corrosion. When the working medium temperature reaches 80, the protective layer must be effective.

    5. The oil temperature shall not exceed the allowable value. Zui height shall not exceed 75. Otherwise, the cooler must be checked, otherwise the road may not pass through, and it is eliminated.

    6. Check the oil quality and quantity every half a year to confirm whether the oil quality is poor and whether the oil quantity is sufficient.

    7. All pressure gauges and galvanometers must be intact.

    8. All oil pipe joints shall be free of oil leakage. Do not loosen the cylinder screws.

    9. In addition to the hydraulic protection safety valve of the protective door, the hydraulic safety system is mainly realized by the system safety valve. The manufacturer has set Zui large allowable value and closed it. When the pressure value exceeds the set specified value, the system safety valve will be opened and adjustment without authorization is strictly prohibited.

    10. The safety valve limits the pressure of the hydraulic system, protects the operator and prevents the connecting part of the hose and steel pipe from being damaged due to excessive pressure; At the same time, protect the hydraulic system from wrong damage. The safety valve protects the oil pump in the hydraulic driving device from overload, and it is not allowed to adjust the system safety valve under any circumstances.
