Milti pistion pressure hydraulic green sand molding machine

ZD hydraulic multi-contact molding machine belongs to a semi-automatic molding machine.Is through a number of hydraulic cylinder thrust compaction sand sand in the sand box, so that the sand get uniform uniform strength requirements, the use of jacking rod jacking sand box, to achieve the effect of the mold.This equipment is generally used in pairs. One machine is used for loading and the other machine is used for unloading.The hydraulic system adopts double pump control.When the contact is rapidly extended, the two pumps supply oil at the same time, and the high pressure pump is used for oil supply in real time.
