Description
Technical field
The utility model relates to a kind of QA control system, and especially servo plastic-injection moulding machine plays the control system of good result in forming thin-walled plastic product.
Background technology
In prior art, during using servo motor driven oil pump as the hydraulic power supply of plastic-injection moulding machine, when doing injection moulding action, servomotor must accelerate to setting speed value or peak from zero, general servomotor need experience the 50-100ms time from static to maximum speed, general direction valve needs about more than 50ms from closed condition to opening completely, therefore can run into melting plastics to be difficult to fill full mould when forming thin-walled plastic product, lead the phenomenon of the shaping instability of plastic member product processed, the rising of substandard product rate, time serious, equipment cannot normally be produced.
Utility model content
Technical problem to be solved in the utility model overcomes deficiency of the prior art and provides a kind of structural design advantages of simple, simple and convenient operation and maintenance quick, and the QA control system of standard servo injection machine of not conflicting with other function.
The technical scheme in the invention for solving the above technical problem is: the QA control system of this standard servo injection machine, comprise oil pump, servomotor, servo controller, pressure sensor, injection machine CPU, it is characterized in that: be also provided with four relays, proportional direction valve and ratio pressure flow valve, four described relays are connected with injection machine CPU, ratio pressure flow valve is connected with injection machine CPU, and proportional direction valve is connected with ratio pressure flow valve and oil cylinder respectively.
Servomotor described in the utility model is connected with oil pump and servo controller respectively, oil pump is connected with pressure sensor, pressure sensor is connected with servo controller, servo controller is also connected with injection machine CPU, also be connected with ratio pressure flow valve after oil pump Bonding pressure sensor, ratio pressure flow valve is connected with injection machine CPU and proportional direction valve respectively, and proportional direction valve is connected with oil cylinder, described injection machine CPU is also connected with four relays.
The utility model, in the control system of primary standard servo-drive plastic-injection moulding machine, increases by two groups of Analog control, thus more easily reaches QA object.
The utility model increases comparative example pressure flow valve and controls, and makes the pressure of ratio pressure flow valve, flow rates controlled.Increase and servo controller is controlled, servomotor is exported with maximum (top) speed always.The utility model is undertaken controlling by ratio pressure flow valve and servo controller control between switching, action can be controlled fast.The pressure signal of the utility model also by making pressure sensor detect when carrying out injection machine action does not feed back, and makes operating pressure, flow by ratio pressure flow valve setup control.
The utility model compared with prior art has the following advantages: 1, the real time response speed of injection machine action is fast.2, the response time of servomotor, direction valve is reduced.3, can switch with original control system.4, the problem that standard servo machine is difficult to forming thin-walled plastic product can be solved.5, the time of molding cycle can be shortened.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, the utility model comprises oil pump 1, servomotor 2, servo controller 3, pressure sensor 4, ratio pressure flow valve 5, proportional direction valve 6, oil cylinder 7, injection machine CPU8, four relays 9.
Servomotor 2 is connected with oil pump 1 and servo controller 3 respectively, oil pump 1 is connected with pressure sensor 4, pressure sensor 4 is connected with servo controller 3, servo controller 3 is also connected with injection machine CPU8, also be connected with ratio pressure flow valve 5 after oil pump 1 Bonding pressure sensor 4, ratio pressure flow valve 5 is connected with injection machine CPU8 and proportional direction valve 6 respectively, and proportional direction valve 6 is connected with oil cylinder 7, described injection machine CPU8 is also connected with four relays 9.
The present invention drives oil pump 1 to oil cylinder 7 pipeline fuel feeding by servomotor 2, and injection machine CPU8 provides maximum pressure, flow to export for servo controller 3.Communication between four relay 9 cut-out pressure sensors 4 and servo controller 3, makes servo-control system be in opened loop control state always.Ratio pressure flow valve 5 is oil piping system control system pressure, flow.Injection machine CPU8 exports control makes proportional direction valve 6 open fast, and system liquid force feed promotes piston rod movement fast.
Above content described in this description is only to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
