Description
Technical field
The utility model belongs to mechanical equipment technical field, relates in particular to a kind of vacuum extractor.
Background technology
The mould of die casting machine needs to use vacuumizing device that mould inside is vacuumized when closure is injected liquation.Mostly comprise vavuum pump, pressure accumulation tube in the vacuumizing device of prior art and be installed in the vacuum valve at mould place and the pipeline of configuration, in pipeline, then add filter.Its shortcoming is that the complex structure volume is big, and noise is big, and automaticity is low, and pressure control is inaccurate, and filter effect is bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, vacuum extractor that automaticity is high is provided.
The technical solution of the utility model is: a kind of vacuum extractor, it comprises vavuum pump and vacuum tank, it is characterized in that: the mould air inlet pipeline that is communicated with die casting machine is set on the top of vacuum tank, the outlet pipe and the pressure regulation pipeline that is connected the pressure regulation vacuum valve that are communicated with vavuum pump, on air inlet pipeline, also be provided with the air inlet ball valve, air intake filter and intermediate ball, on the pressure regulation pipeline, also be provided with check-valves, on outlet pipe, also be provided with and give vent to anger vacuum valve and go out air filter, the branch road of a connection magnetic valve also is set on the pipeline that goes out between air filter and the vavuum pump, the pressure sensor of on vacuum tank, installing, controller respectively with pressure sensor, the pressure regulation vacuum valve, the vacuum valve of giving vent to anger, magnetic valve and vavuum pump control connection.
Discharge the liquid of vacuum tank inside for convenience, be provided with drainpipe and draining valve in the bottom of vacuum tank.
In order to reduce noise, muffler has been installed respectively on pressure regulation vacuum valve, check-valves and magnetic valve.
As further improvement of the utility model, at air inlet pipeline an external electromagnetic valve module has been installed also, the external electromagnetic valve module comprises external vacuum valve, external sensor and an external filter.
The utility model compared with prior art has following advantage: the utlity model has the unnecessary air that can get rid of in the die casting machine mould, product precision height, forming effect height, working strength height, the long service life that makes production.Particularly by controller vacuum pressure is responded to, realized the automation control to vacuum valve and magnetic valve, the automaticity height guarantees that vacuum pressure is stable.The generation of the oil sprayer oil smoke of employed vavuum pump outside and noise is few in this device, belongs to low sound level pump.This device integral body has only 2 casings of a casing and conventional vacuum device to compare very small and exquisite, compact.
Description of drawings
Fig. 1 is the utility model vacuum extractor schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, a kind of vacuum extractor, it comprises vavuum pump 1 and vacuum tank 6, on the top of vacuum tank 6 the mould air inlet pipeline that is communicated with die casting machine, the outlet pipe and the pressure regulation pipeline that is connected pressure regulation vacuum valve 8 that is communicated with vavuum pump 1 are set, are provided with drainpipe and draining valve 7 in the bottom of vacuum tank 6.On air inlet pipeline, also be provided with air inlet ball valve 15, air intake filter 13 and intermediate ball 12; On the pressure regulation pipeline, also be provided with check-valves 10, muffler 9 and muffler 11 be installed respectively at pressure regulation vacuum valve and check-valves; On outlet pipe, also be provided with and give vent to anger vacuum valve 5 and go out air filter 4, the branch road of a connection magnetic valve 2 also is set on the pipeline that goes out between air filter 4 and the vavuum pump 1, muffler 3 is installed on magnetic valve 2; The pressure sensor of on vacuum tank 6, installing 14; At air inlet pipeline an external electromagnetic valve module 16 has been installed also, external electromagnetic valve module 16 comprises an external vacuum valve 19, external sensor 18 and external filter 17; Controller respectively with pressure sensor 14, pressure regulation vacuum valve 8, the vacuum valve 5 of giving vent to anger, magnetic valve 2, external sensor 18 and vavuum pump 1 control connection.
Continue in conjunction with the accompanying drawings the operation principle of summary the utility model product below.
When normally vacuumizing operation: tracheae linked to each other with mould on the die casting machine to connect, draining valve 7, pressure regulation vacuum valve 8, intermediate ball 12, air inlet ball valve 15 are closed earlier, connect power supply, start vavuum pump, open the vacuum valve 5 of giving vent to anger simultaneously, begin the vacuum tank extracting vacuum.Treat that vacuum tank reaches the setting negative pressure and a period of time final vacuum pump of delaying time stops automatically.When the mould to die casting machine vacuumizes, connect pipeline earlier, intermediate ball 12, air inlet ball valve 15 are opened earlier, treat to reach pressure balance with dies cavity in the vacuum tank, thereby reach the purpose that vacuumizes.
Vacuum is during less than operational pressure: when vacuum in the vacuum tank when setting negative pressure, the vacuum valve 5 of giving vent to anger cuts out, vavuum pump quits work automatically.
Vacuum is during greater than operational pressure: when vacuum in the vacuum tank when setting negative pressure, the vacuum valve 5 of giving vent to anger is opened, vavuum pump is started working automatically.
