It is four.
The utility model has the advantages that the utility model is provided with oil path block on the oil pipe between drive cylinder and pumping plant, make system
Oil pressure is more stable, simultaneously because the distance between the level-one mouth of oil path block and each second level mouth are equal, therefore can guarantee each driving
Oil cylinder oil inlet and fuel-displaced simultaneously, i.e., each drive cylinder moves synchronously, thus make top board is synchronous with the movement of lower platen to carry out, guarantor
Card die sinking quality.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawings and examples:
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the structural schematic diagram of oil path block in the utility model embodiment.
Specific embodiment
Referring to Figures 1 and 2, the utility model is a kind of oil circuit voltage-stabilizing system of moulding machine, including top board 1, lower platen 2
With pumping plant 3, top board 1 and lower platen 2 are set on four guide posts 4 by the aperture of four corners, the top of top board 1 and pushing
Plate 2 is respectively arranged below at least two drive cylinders 5, the piston rod for the drive cylinder 5 being located above and underlying drive
The piston rod of dynamic oil cylinder 5 is supported with the lower end surface of the upper surface of top board 1 and lower platen 2 respectively to be contacted；It further include four oil circuits
Block 6, each oil path block 6 is equipped with a level-one mouth 61 and at least two second level mouths 62, between level-one mouth 61 and each second level mouth 62
It is equidistant, the level-one mouth 61 of each oil path block 6 is connected by oil pipe 7 and pumping plant 3, and four oil path blocks 6 divide for the first oil path block, the
The oil inlet of two oil path blocks, third oil path block and the 4th oil path block, each drive cylinder 5 being located above passes through oil pipe 7 and first
The second level mouth 62 of oil path block connects one to one, and the oil outlet for each drive cylinder 5 being located above passes through oil pipe 7 and the second oil circuit
The second level mouth 62 of block connects one to one, and the oil inlet of underlying each drive cylinder 5 passes through oil pipe 7 and third oil path block
Second level mouth 62 connects one to one, and the oil outlet of underlying each drive cylinder 5 passes through the second level of oil pipe 7 and the 4th oil path block
