The purpose of the technical program is to provide a kind of accumulator to assist high speed injection mechanism for existing injection machine, when injection machine is worked, this injection mechanism provides higher injection pressure and injection moulding speed for the hydraulic system of injection machine, thus shortened injection machine production cycle, reduced product cost, improved product profit.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the accumulator of injection machine is assisted high speed injection mechanism, comprises and main oil pump P
1The auxiliary oil pump P that same input is arranged
2, main oil pump P
1Drive auxiliary oil pump P by motor MTR
2Output and electromagnetic relief valve V
2Input and check valve V
1Input connect check valve V
1Output and accumulator B
2Interface connect accumulator B
2In be full of nitrogen, accumulator B when injection machine is not worked
2Inner nitrogen pressure is about 70% of an injection machine operating pressure, described accumulator B
2Interface Pressure gauge B is installed
1And with Pressure gauge B
1On force value be transferred to the pressure switch B of injection machine computer
3, described accumulator B
2Interface also with inserted valve V
4Input connect inserted valve V
4Output connect the injection moulding oil cylinder of injection machine, inserted valve V
4The last first reversal valve V that its work of control is installed
5With shuttle valve V
6, the first reversal valve V
5By the control of injection machine computer, described check valve V
1Output also with the second reversal valve V
3Input connect described oil pump P
2Output also with electromagnetic relief valve V
2Input connect the second reversal valve V
3With electromagnetic relief valve V
2Output by cooler F
2Be connected on the fuel tank main oil pump P in the fuel tank
1With auxiliary oil pump P
2Filter F is installed in the porch
1
This injection mechanism is by the control of the computer in the injection machine control device, and its operation principle is as follows: when the user selects to use accumulator B in computer
2The time, open motor, auxiliary oil pump P
2Pump to accumulator B
2, make accumulator B
2In the nitrogen compression that is full of in advance, cause nitrogen pressure to raise, this force value is at Pressure gauge B
1And by pressure switch B
3Be transferred to computer, when supercharging pressure value that this force value is set in greater than computer, the accumulation of energy process finishes.This moment, computer outputed signal to electromagnetic relief valve V
2Make electromagnetic relief valve V
2Open auxiliary oil pump P
2The oil of extracting out is by electromagnetic relief valve V
2Get back to fuel tank, at this moment accumulator B
2In pressure keep equal with the predefined supercharging pressure value of computer.When injection machine carried out action of injection, computer sent signal and gives the first reversal valve V
5, by the first reversal valve V
5Control shuttle valve V
6Spool move, thereby with inserted valve V
4Open.The pressure oil that is full of in the accumulator is by inserted valve V like this
4The pressure oil that enters in injection cylinder and the original injection cylinder converges, and finishes action of injection, and injection speed is improved greatly.After action of injection finishes, accumulator B
2Tapping finishes, and computer sends signal and gives electromagnetic relief valve V
2, make electromagnetic relief valve V
2Close, so auxiliary oil pump P
2The oil of extracting out enters accumulator B once more
2In carry out topping up, the next circulation of beginning.If the user selects not use accumulator B in computer
2The time, computer outputs signal to the second reversal valve V
3, the second reversal valve V
3Open auxiliary oil pump P
2The oil of extracting out is by the second reversal valve V
3Get back to fuel tank, the auxiliary high speed injection mechanism of accumulator this moment does not work.
