Description
Technical field
The utility model is related to a kind of evacuated die-casting process control systems effectivelying prevent aluminium alloy clogging.
Background technology
Existing evacuated die-casting process control system schematic diagram is as shown in Figure 1：Vacuum pump is to be used for die casting machine in process of production
The air of mold cavity is discharged, prevents molten metal and enters after die cavity to be formed to roll and sand holes, enhance the consistency of product.It is original true
Using very simple control model, main body mechanism is for pneumatics casting control and die casting vacuum system：It is vacuum pump 1, vacuum tank 2, true
Empty valve 3, pressure sensor PG, mechanical valve 4, die cavity 5.Vacuum opens first forvacuum tank inner air and reaches a setting value,
Vacuum-pumping valve 3 is opened by vacuum pump system station PLC controller 5 after being provided by die casting machine signal, starts to vacuumize, closing side
Formula is closed for aluminium alloy filling mode, is entered containing part molten aluminum in air-flow, no blowback sweeping device, and valve and pipeline are easy to block up
Plug.
And existing evacuated die-casting process control system, function is swept without design blowback well, due to vacuum valve or vacuum tube
Road blocking causes vacuum system pressure value that cannot continuously meet production requirement, and interiors of products contains portion gas, gas in cavity
Cannot 100% discharge, lower subjob can just be carried out by needing to clear up valve or pipeline；Injection cannot be accurately monitored in real time simultaneously
Speed and shot position lead to that sufficient pipeline cannot be carried out in extremely short injection process or valve blowback are swept, cast member production
Period is short, if purging cannot be completed within the effective time, it is bad that next process will result in product, next one process
It just can not operation.
Invention content
The purpose of this utility model is that a kind of evacuated die-casting process control system effectivelying prevent aluminium alloy clogging of design,
The control system has purge time sufficient, and blowback flow is big, and blowback pressure is strong, enhances valve and pipeline antipollution power, reaction
Fireballing advantage substantially increases vacuum exhaust efficiency compared with the control system of the prior art, reduces molten aluminum and blocks pipe
Road.
To achieve the above object, the utility model provides the following technical solutions：One kind effectivelying prevent aluminium alloy clogging
Evacuated die-casting process control system, including controller, and be connected with controller vacuum tank, vacuum pump, vacuum valve, flowmeter,
Pressure sensor, vacuum machine valve, die casting machine and blow down valve, wherein vacuum pump is connect with the vacuum tank, for aspirating
The air-flow in vacuum tank is stated, meanwhile, the vacuum valve is provided on the vacuum tank, the vacuum valve is true with the die casting machine
Empty mechanical valve is connected by pipeline, while blow down valve, flowmeter and pressure sensor are provided on the pipeline, the blow down valve
The nitrogen of blowout blows to target by channel of nitrogen.
Further, die cavity is provided in the die casting machine, while the vacuum machine valve is set on the die cavity.
Further, it is additionally provided with displacement encoder on the die casting machine.
Further, the controller is PLC.
Further, further include being set to display screen on the vacuum tank, for showing current operation state picture.
When the system specific works, the parameter of PLC sets requirements is first passed through, vacuum machine valve is in off state at this time, gas
Stream enters vacuum pump by pipeline by vacuum tank, and the pressure in vacuum tank 2 continues to decline at this time, it is ensured that pressure is in setting range value
Interior, die casting machine starts, and mold clamping signal feeds back to PLC controller, and vacuum valve is opened in PLC controller control, starts to aspirate mould
The air of intracavitary, air-flow are sucked vacuum tank again, and when die casting machine pushes, aluminium alloy rises to vacuum machine valve with air-flow
When touch point, by alloy pressure quick closedown channel, vacuum valve is closed immediately, PLC controller at this time by pressure sensor,
Flowmeter judges whether current value is normal, and when signal is sent to PLC controller in place, vacuum blow down valve is opened for die casting machine die sinking,
Start to purge, waits the pressure that completion PLC controller meeting automatic decision flowmeter to be purged provides whether normal, if normal etc.
Wait for that next cycle starts.
The utility model has the advantage of：The evacuated die-casting process control system, effectively improves because of the process in high speed die casting
In, the time is short, and speed is fast, can not effectively clear up internal pipeline and lead to not extract gas in die cavity, cause the bad of product
Rate.The evacuated die-casting process control system more accurately controls each situation point in injection process in press casting procedure simultaneously, complete
It is complete to have prevented the pipeline putty caused by vacuumizing or be vacuum-evacuated the factors such as inefficiency.
