Abstract
The utility model discloses a device used in the vacuum casting production line. The production line for multi-split vacuum casting machines comprises a vacuum pump, surge tanks, a multi-channel distributor, electromagnetic valves, casting machines, etc. The vacuum pump is connected with the surge tanks through a vacuum tube provided with a stop valve; a plurality of casting machines which are connected in parallel with the multi-channel distributor are connected with the surge tanks through vacuum tubes. The electromagnetic valves are arranged on the vacuum tubes between each casting machine and the multi-channel distributor, and each casting machine is provided with a deflation valve. The vacuum condition required by each casting machine is controlled by a programmable control module. The device used in the vacuum casting production line has the advantages that adopting a single vacuum pump can effectively reduce the equipment investment and the energy consumption, and adopting the PLC technology can control the distribution and the use of a vacuum air source and can maintain the vacuum degree of the surge tanks, thereby realizing that a plurality of vacuum casting machines share one vacuum pump, and achieving the high-efficient production.
Description
Technical field
The utility model belongs to the type vacuum injecting and forming technical field, is specifically related to the apparatus for production line that a vavuum pump and a plurality of forming machine constitute.
Background technology
Type vacuum injecting and forming machine is quick copy or the equipment of manufacturing experimently all kinds of plastic parts products, can shorten construction cycle, the minimizing development cost of new product and reduce development risk.Along with the continuous expansion of type vacuum injecting and forming product applications, the characteristics that the small lot batch manufacture order is many, delivery date is tight have been formed gradually.Self-evident, only use a forming machine, production efficiency is low, is difficult to satisfy requirement of client.The structure of at present popular type vacuum injecting and forming machine is: every forming machine is equipped with a vavuum pump, and the silica gel degassing and plastic parts pouring technology are united two into one, and two kinds of technologies can not be worked simultaneously.If form a type vacuum injecting and forming production line by many forming machines simply, there is the waste of resource, not a kind of embodiment of high-efficiency and economic.If can constitute the type vacuum injecting and forming production line with a vavuum pump and two or more forming machine, just can reduce the device fabrication cost; Drop into same funds, can dispose more unit, enhance productivity.Problem to be solved in the utility model that Here it is.
Summary of the invention
The purpose of this utility model is, provides a kind of and provides vacuum source by a vavuum pump and a vacuum tank to a plurality of forming machines operating room, promptly one drags many type vacuum injecting and formings machine production line.It utilizes the start and stop of PLC (programmable control module) technology and closed loop feedback control technology control vavuum pump, make vacuum tank have more stable vacuum, thereby realize that a plurality of forming machines share a vavuum pump, enhance productivity and energy saving purposes to reach.
The realization the technical solution of the utility model is: separate unit vacuum pump type notes type production line has vavuum pump 1, stop valve 2, vacuum tube 3, vacuum tank 4, vacuum meter 5, multichannel distributor 6, magnetic valve 7 and forming machine 8 etc.; System, control circuit has pressure transmitter 10 and programmable control module (PLC) 11 etc.The vacuum tube 3 of vavuum pump 1 through stop valve 2 is housed joins with vacuum tank 4; Several forming machines 8 are parallel to multichannel distributor 6, join through vacuum tube 3 and vacuum tank 4.On the vacuum tube 3 between each forming machine 8 and the multichannel distributor 6 magnetic valve 7 is housed, each forming machine 8 is furnished with vent valve 9.In order to control the vacuum of forming machine 8, vacuum tank 4 is furnished with vacuum meter 5 at the top, and pressure transmitter 10 is housed; Each forming machine 8 also is furnished with vacuum meter 5 and pressure transmitter 10.For the required operating pressure of each forming machine is controlled, adopt the PLC control circuit.The input of programmable control module 11 is divided into two the tunnel: the pressure transmitter 10 of leading up to is connected to each forming machine 8 respectively; Another road is connected to vacuum tank 4 by the pressure transmitter 10 of same type.The output of programmable control module 11 also is divided into two the tunnel: the one tunnel and is connected to each magnetic valve 7; Another road is connected to vavuum pump 1 by relay contactor 12 (relay and contactor and for one).
When 1 pair of vacuum tank 4 of vavuum pump was bled, programmable control module (PLC) 11 was according to the start and stop of the feedback signal control vavuum pump 1 of pressure transmitter 10, and when vacuum reached the set upper limit value, vavuum pump 1 quit work; When vacuum was lower than the regulation lower limit, vavuum pump 1 starts bled.The higher limit of vacuum and lower limit are according to the concrete required condition enactment of notes type object, and vacuum tank 4 can be forming machine 8 stable vacuum is provided.When certain forming machine 8 need vacuumize, open with forming machine 8 corresponding magnetic valves 7, connect the vacuum source of vacuum tank 4.When programmable control module (PLC) 11 detects forming machine 8 operating rooms and reaches the vacuum of setting, make magnetic valve 7 closures, cut off vacuum source.When forming machine 8 needs venting, can adjust corresponding vent valve 9 by manual or automatic mode and carry out.
Description of drawings
Accompanying drawing is the structural representation that each parts of the utility model connect
The specific embodiment
Below by specific embodiment the utility model is further described.
Press shown in the accompanying drawing each parts is connected.Present embodiment is provided with 3 forming machines, and forming machine inner cavity size 460 * 480 * 700 (mm), the volume of vacuum tank are 3 times of each forming machine volume, and the vavuum pump maximum vacuum of bleeding is 95Pa.
Start vacuum pump switch, vavuum pump is bled to vacuum tank, and programmable control module (PLC) is then controlled the start and stop of vavuum pump according to the feedback signal of pressure transmitter, and when forming machine operating room pressure reached 100pa, vavuum pump quit work; When operating room's pressure rose to 500pa, PLC gave an order, and vavuum pump starts bleeds, and keeps 3 required stable vacuums of type vacuum injecting and forming machine.Need carry out work because of producing, when promptly forming machine need vacuumize, open the vacuum switch on the corresponding operating panel, corresponding solenoid valve is switched on, and connects the vacuum source of vacuum tank simultaneously; In type vacuum injecting and forming work when programmable control module (PLC) detects this forming machine operating room and reaches the pressure 500pa of setting, control respective electrical magnet valve coil blackout, its valve closes is cut off vacuum source.The notes type finishes, and adopts open loop control mode to adjust vent valve and exits.
The beneficial effects of the utility model are: adopt the separate unit vavuum pump can effectively reduce equipment investment and energy consumption, adopt The PLC technology can be controlled the distribution of vacuum source and use and keep the vacuum of vacuum tank, thereby realizes a plurality of type vacuum injecting and formings Machine is shared a vavuum pump, and reaches the purpose of High-efficient Production.
