In the invention, injection moulding is realized under an ultrahigh-speed condition through the internal and external pressure injection controller, an effect of forming an ultrathin precise product of which the wall thickness is less than 0.12 mm is realized, the product quality is guaranteed by use of the mould cavity pressure sensor and the injection cylinder pressure sensor, and the operations are performed by use of the single chip, thereby realizing automation and being simple and convenient.
Description
Technical field
The present invention relates to the injection moulding controller, relate in particular to a kind of interior external pressure injection moulding controller.
Background technology
At present, in injection moulding machine, screw rod is advanced in the cylinder in heating, will be heated the resin injection of fusion and be filled in the die cavity of die device, in this die cavity, make the resin cooling curing, through such moulding moulded product with high pressure.In the conventional art, the injection mo(u)lding controller adopts the semi-closure ring type control mode that the injection cylinder position is controlled usually, carries out extrusion modling; This control mode can not obtain the resin pressure changing value in the mould; Yet along with the development of ultra-thin high-accuracyization of naval stores, very small outer unrest also can cause the deviation of condition of molding; Produce defective products, even cause the breakage of mould.
Summary of the invention
To above-mentioned shortcoming, the technical issues that need to address of the present invention provide a kind of interior external pressure injection moulding controller.
For achieving the above object; The technical scheme that the present invention adopts is: external and internal pressure injection moulding controller; Comprise cavity pressure sensor, injection cylinder pressure sensor, servomotor, servo valve and single-chip microcomputer; Cavity pressure sensor, injection cylinder pressure sensor and servomotor are connected with single-chip microcomputer through cable respectively, and servomotor is connected with servo valve through cable.
Said cavity pressure sensor is installed on the mould, and said injection cylinder pressure sensor is installed in the injection cylinder of injection machine.
Also comprise displacement transducer and temperature sensor, said displacement transducer is installed on the mould, and is connected with single-chip microcomputer through cable, and said temperature sensor is installed in the injection cylinder of injection machine, and is connected with single-chip microcomputer through cable.
Advantage of the present invention: interior external pressure injection moulding controller is implemented in injection mo(u)lding under the superfast condition; Reach the effect of the ultra-thin accurate formed product of wall thickness below 0.12mm; Utilize cavity pressure sensor and injection cylinder pressure sensor, guarantee the quality of product, utilize single-chip microcomputer to operate; Realize automation, simple and convenient.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Wherein: 1, cavity pressure sensor, 2, the injection cylinder pressure sensor, 3, servomotor, 4, servo valve, 5, single-chip microcomputer, 6, displacement transducer, 7, temperature sensor, 8, mould, 9, injection cylinder.
The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
As shown in Figure 1; External and internal pressure injection moulding controller of the present invention; Comprise cavity pressure sensor 1, injection cylinder pressure sensor 2, servomotor 3, servo valve 4, single-chip microcomputer 5, displacement transducer 6 and temperature sensor 7, cavity pressure sensor 1 is installed on the mould, and injection cylinder pressure sensor 2 is installed in the injection cylinder of injection machine; Displacement transducer 6 is installed on the mould 8; Temperature sensor 7 is installed in the injection cylinder 9 of injection machine, and cavity pressure sensor 1, injection cylinder pressure sensor 2, servomotor 3, displacement transducer 6 and temperature sensor 7 are connected with single-chip microcomputer 5 through cable respectively, and servomotor 3 is connected with servo valve 4 through cable.
Further specify in the face of the course of work of the present invention down: cavity pressure sensor 1 is gathered the die cavity internal pressure; When the cavity pressure signal is lower than setting value, to handle through single-chip microcomputer 5, pressure instruction is opened; Start servomotor 3; Servomotor 3 drives servo valve 4 and opens, and increases cavity pressure, makes the die cavity internal pressure reach setting value; When the cavity pressure signal is higher than setting value, to handle through single-chip microcomputer 5, the pressure instruction shutdown starts servomotor 3, and servomotor 3 drives servo valve 4 and cuts out, and reduces cavity pressure, makes the die cavity internal pressure reach setting value; Displacement transducer 6 supervision molding 8 positions guarantee mould 8 positions in reasonable range, resin temperature in the temperature sensor 7 monitoring injection cylinders 9; Guarantee product quality, whole process is regulated through single-chip microcomputer 5, and the realization closed loop is controlled in real time; Simple to operation, realize working automation.
