Detailed description of the invention
Referring to figs. 1 to the evacuated die-casting process system in embodiment illustrated in fig. 5, including the vacuum valve 1 with valve rod 11 and spool 12. This vacuum valve 1 has open mode and closed mode, and at which when open mode, valve rod 11 stretches out and is in communication with the outside internal for spool 12, and at which when closed mode, valve rod 11 is retracted spool 12 and outer closures. Evacuated die-casting process system also includes oil cylinder 3, for driving the opening and closing of vacuum valve 1, oil cylinder 3 output shaft stretches out to be opened corresponding to vacuum valve 1, the contracting of oil cylinder 3 output shaft is closed corresponding to vacuum valve 1, output shaft screw thread at oil cylinder 3 is connected to adapter 4, and the end of valve rod 11 is fixedly connected on the end face of adapter 4.
Evacuated die-casting process system also includes rapid-closing device, switches to the moment of closed mode at valve rod 11 from open mode, it is possible to direct or indirect applies active force to adapter 4, so that valve rod 11 quick closedown.
With reference to the first embodiment of Fig. 1 and Fig. 2, rapid-closing device includes first ring the 51, second ring 52 and is in the spring 53 between the first ring 51 and the second ring 52.First ring 51 is socketed in the outer wall of valve rod 11 bottom, its bottom is connected to adapter 4 end face, and the second ring 52 is socketed in the outer wall in the middle part of valve rod 11, and its top connects spool 12 end face, spring 53 is set in valve rod 11 periphery, and the two ends of spring 53 connect the end face of the first ring 51 and the second ring 52 respectively. When oil cylinder 3 drives valve rod 11 to stretch out, spring 53 is compressed and is stored bigger elastic force, when oil cylinder 3 switches to and drives valve rod 11 to retract, adapter 4 is applied a downward elastic force by spring 53, the pulling force that valve rod 11 is retracted by this elastic force and oil cylinder 3 simultaneously acts on adapter 4, valve rod 11 is transmitted force to, thus driving valve rod 11 quickly to close by adapter 4.
The rapid-closing device of the present embodiment, the effect closing rapidly vacuum valve 1 can not only be played, and because providing the power major part that vacuum valve 1 cuts out is provided by elastic force, the active force of adapter 4, valve rod 11 is reduced by oil cylinder outfan, therefore, abrasion between oil cylinder outfan and adapter 4 also alleviates significantly, and the problem that vacuum valve 1 is not closed completely also is alleviated greatly.
The second embodiment as shown in Figure 3 and Figure 4, rapid-closing device acts on the hydraulic oil entering oil cylinder 3, thus indirectly adapter 4 being applied active force.

Control block 61 be provided with total oil-in 611, total oil-out 612, pressurization mouth 613 and connect the oil cylinder interface 614 of oil cylinder in vacuum valve. Wherein, total oil-in 611 and total oil-out 612 can pass through the hydraulic system 69 outside pipeline connection, and oil cylinder interface 614 can pass through pipeline and connect described oil cylinder 3.
Described distributing valve 62 has pressure oil inlet P, inlet port T and actuator port A, and wherein, oil cylinder interface 614 connects with actuator port A, and total oil-out 612 connects with inlet port T. Described total oil-in 611 connects by being arranged on the oil inlet passage 64 controlled in block 61 with pressure oil inlet P, and oil inlet passage 64 connection pressurization mouth 613, accumulator 63 is connected on pressurization mouth 613, and total oil-in 611 is also circumscribed with non-return valve 65.
In press casting procedure, first the fluid in hydraulic system 69 enter from non-return valve 65 and total oil-in 611 and control in block 61, and now distributing valve 62 is closed, simultaneously because fluid cannot reflux, fluid enters accumulator 63 at pressurization mouth 613 and stores oil pressure; The moment of high pressure injection, distributing valve 62 controls actuator port A and opens, the pressure that accumulator 63 stores passes through fluid moment from entering actuator port A and oil cylinder interface 614, thus oil pressure is supplied to oil cylinder, control quickly stretching out and the quick closedown of vacuum valve of oil cylinder output shaft, thus improve the response speed of vacuum valve, it is ensured that the accuracy of its running.
Accumulator 63 is diaphragm accumulator, utilizes nitrogen storage pressure. Distributing valve 62 is arranged on control block 61, and oil cylinder interface 614 connects by being arranged on the oil transportation channel 67 controlled in block 61 with actuator port A, and total oil-out 612 connects by being arranged on the drainback passage 68 controlled in block 61 with inlet port T. Above-mentioned oil transportation channel 67, drainback passage 68 and oil inlet passage 64 separate and non-interference mutually, are only connected by distributing valve 62.
Oil cylinder interface 614 is separately positioned on distributing valve 62 and controls the both sides that block 61 is relative, so so that the distance of oil transportation channel 67 is shorter, and can reduce bending, thus reducing the loss of pressure.
The present embodiment only has an oil cylinder, therefore only needs an actuator port.But in other cases, perhaps oil cylinder and vacuum valve have multiple, now control block 61 and be provided with at least two oil cylinder interface 614, it is possible to external plural oil cylinder and corresponding vacuum valve, thus plural vacuum valve is controlled.
Further, distributing valve 62 is provided with at least two actuator port, is actuator port A, B respectively, and each actuator port at least connects an oil cylinder interface 614, it is possible to controlled the switching of different operating hydraulic fluid port A by distributing valve 62, thus controlling different oil cylinders and vacuum valve.
Further, distributing valve 62 is two-position four-way valve, has two actuator ports A, B, controls block 61 and has 4 pressurization mouths 613, and each actuator port controls 2 pressurization mouths 613.
In the above-described embodiment, with reference to Fig. 1 and Fig. 2, oil cylinder 3 outer wall is provided with cooling-part 7, and oil cylinder 3 is carried out water-cooled.
With reference to Fig. 5 to Fig. 7, vacuum valve 1 is fixed in a base 2, accordingly, the cavity holding spool 12 it is provided with in base 2, it is additionally provided with the taking-up passage of spool 12 in base 2, namely described vacuum valve 1 can take out in base 2, so greatly facilitates the installation and removal of vacuum valve 1.
Specifically, with reference to Fig. 5, base 2 upper surface is provided with groove 21, and spool 12 is contained in groove 21, and spool 12 can take out from the upper end open of groove 21. With reference to Fig. 5 to Fig. 7, spool 12 outer wall be provided with outward flange 121, this outward flange 121 only exists with in a part for spool 12 circumference, and the also removable briquetting 8 that is provided with in groove 21, briquetting 8 is bolted in the groove 21 of base 2. Outward flange 121 is clamped by the bottom face of briquetting 8 and groove 21, thus being fixed by spool 12. In the above-described embodiment, described groove 21 forms the taking-up passage of spool 12.
The above be this utility model preferred embodiment, it is not intended that the restriction to this utility model protection domain.
