Abstract
The utility model relates to a feed oil-way of full automatic rotary injection molding machine which is in series composed of an oil tank, a scale valve, a change valve and an injection gum oil pump, and is in parallel connected with an oil pump, an accumulator and an inserting installation valve in series connecting to an adding pressure oil way. An inlet of the adding pressure oil way is connected with the oil tank. The outlet of the adding pressure oil way is connected with the feeding oil way in the front of the injection gum oil pump. The utility model can improve the oil pressure of the injection gum oil pump by pressure increase of the adding pressure oil way to the injection gum oil pump, thereby greatly improving the oil pressure of the injection gum oil pump and improving the injection speed by 6 times to 10 times.
Description
The utility model relates to the full-automatic rotary disk injection moulding machine injection of a kind of computer oil circuit device, the full-automatic rotary disk injection moulding machine high speed and high pressure of particularly a kind of computer injection oil circuit device.
Existing known full-automatic rotary disk injection moulding machine injection oil circuit all is to be composed in series by proportioning valve, reversal valve, injection oil pump etc., does not have Pressure Increasing Oil-Line, and injection oil piping system oil pressure is not high, and the injection velocity pressure is not high enough during work.
The purpose of this utility model is the full-automatic rotary disk injection moulding machine high speed and high pressure of the computer injection oil circuit device that proposes a kind of high speed and high pressure injection moulding.
Task of the present utility model is finished like this: on the full-automatic rotary disk injection moulding machine injection oil-feed oil circuit that fuel tank, proportioning valve, reversal valve, injection oil pump etc. are composed in series successively, Pressure Increasing Oil-Line that is connected into successively by oil pump, accumulator, inserted valve in parallel, the oil-in of Pressure Increasing Oil-Line is connected on the fuel tank, and the oil-out of Pressure Increasing Oil-Line is connected on the preceding oil-feed oil circuit of injection oil pump.
The utility model can increase substantially the oil pressure of injection oil pump by the supercharging of Pressure Increasing Oil-Line to the injection oil pump, makes injection speed improve 6-10 doubly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the injection asphalt principle figure of the full-automatic rotary disk injection moulding machine high speed and high pressure of the utility model computer injection oil circuit device.
According to shown in Figure 1: the full-automatic rotary disk injection moulding machine high speed and high pressure of the utility model computer injection oil circuit device, on the injection oil-feed oil circuit that fuel tank (1), proportioning valve (2), reversal valve (3), injection oil pump (4) are composed in series successively, Pressure Increasing Oil-Line that is connected into successively by oil pump (5), accumulator (6), inserted valve (7) in parallel, the oil-in of Pressure Increasing Oil-Line (8) is connected on the fuel tank (1), and the oil-out of Pressure Increasing Oil-Line (9) is connected on the preceding oil-feed oil circuit of injection oil pump (4).During work, the hydraulic oil that the oil-out of Pressure Increasing Oil-Line (9) flows out flows to injection oil pump (4), makes the movement velocity of injection oil pump (4) improve 6-10 doubly.
Claims (1)
1, a kind of by fuel tank (1), proportioning valve (2), reversal valve (3), injection oil pump (4) is composed in series the full-automatic rotary disk injection moulding machine high speed and high pressure of the computer injection oil circuit device of injection oil circuit successively, it is characterized in that in fuel tank (1), proportioning valve (2), reversal valve (3), on the injection oil-feed oil circuit that injection oil pump (4) is composed in series successively, in parallel one by oil pump (5), accumulator (6), the Pressure Increasing Oil-Line that inserted valve (7) is connected into successively, the oil-in of Pressure Increasing Oil-Line (8) is connected on the fuel tank (1), and the oil-out of Pressure Increasing Oil-Line (9) is connected on the preceding oil-feed oil circuit of injection oil pump (4).
