a hydraulic circuit for the purposes of closing unit and the injection unit of an injection moulding machine for the processing of plastics.

摘要

the invention relates to a hydraulic circuit for the supply of units of closure and the injection unit of a machine for forming by injection for the processing of plastics.the task of the invention is to reduce the quantity of pipes and conducted between the oil tank and the combination of pumpsin terms of volume and in terms of the number of users of the closing unit and injection.this is achieved by the provision of a central block in the unit of injection valves directly on the tank of the oil.which has the function of the distribution of the flow of oil supplied from the combination of the unit of injection pumps and the closure unit.in this case,the position of the interface for users of the closing unit is prepared directly on the block valves and the position of interface for the unit of injection is in the block collector atthe basis of the injection unit.the block valve is at the same time, the focal point of all the conduits of return and loss to the oil bearing the unit shutdown and the unit of injection into the reservoir of the oil.
