Compare prior art, film vacuum of the present invention attaches control method, utilizes Programmable Logic Controller according to the exhaust order of setting, the vent port exhaust successively that control is corresponding, with guarantee film smooth fit in die cavity.
Description of drawings
The invention will be further described in conjunction with embodiment with reference to the accompanying drawings.
Fig. 1 is the block diagram that is connected of the present invention's preferred embodiments of realizing exhaust apparatus that the film vacuum attaches control method and the vent port of injection mold.
Fig. 2 is the process flow diagram that film vacuum of the present invention attaches the control method preferred embodiments.
Embodiment
Please refer to Fig. 1, film vacuum of the present invention attaches the order that some vent ports that control method is used for controlling an injection mold 10 vacuumize.This injection mold 10 comprises some vent ports that are arranged at die cavity or die cavity periphery, and this vent port is by external exhaust apparatus 60 exhausts.The man-machine interface 50 that this exhaust apparatus 60 comprises some relays, is connected in the vacuum control valve of corresponding relay, is connected in the pressure accumulation tube 16 of corresponding vacuum control valve, the vacuum extractor 18 that is connected in described some pressure accumulation tubes, a Programmable Logic Controller 40 and are connected in Programmable Logic Controller 40.Described man-machine interface 50 can be to described Programmable Logic Controller setting program or input parameter.Described relay all is connected in described Programmable Logic Controller 40, so that be controlled by described Programmable Logic Controller 40.
In the present embodiment, this injection mold 10 is that example describes with three vent port 12a, 12b, 13c only.This vent port is that example describes with three vacuum control valve 15a, 15b, 15c, three pressure accumulation tubes 16 and three relay 20a, 20b, 20c only.
This three vent port 12a, 12b, 12c be three vacuum control valve 15a, 15b, the 15c of external this exhaust apparatus respectively.This three vacuum control valve 15a, 15b, 15c are installed on three pressure accumulation tubes 16 respectively, equate to guarantee this three vent port 12a, pressure when 12b, 12c carry out exhaust.This three pressure accumulations tube 16 all is connected in vacuum extractor 18, and in other embodiments, this vacuum means is set to vacuum pump.
This control method realizes by the Programmable Logic Controller (PLC) 40 of this exhaust apparatus 60.This Programmable Logic Controller 40 is external and control three relay 20a, 20b, 20c, and this three relay 20a, 20b, 20c are connected to this three vacuum control valve 15a, 15b, 15c.This Programmable Logic Controller 40 utilizes man-machine interface 50 to come setting program, and control the conducting of this relay 20a, 20b, 20c by this program, thereby open vacuum control valve 15a, 15b, 15c, with the order that realizes that control vent port 12a, 12b, 12c vacuumize.
During use, the conducting order of relay 20a, 20b, 20c can be set by man-machine interface 50, and be stored in the described Programmable Logic Controller 40.In the present embodiment, by man-machine interface 50 described Programmable Logic Controller 40 is imported and be stored in to evacuation time and the order of vent port 12a, 12b, 13c respectively, with the conducting of pilot relay 20a, 20b, 20c, and then the action of control vacuum control valve 15a, 15b, 15c vacuumizes operation.
Please refer to Fig. 2, when film was delivered between the injection mold 10 by the film feeding machine, vent port 12a, 12b, the 13c of described Programmable Logic Controller 40 these injection molds 10 of control began exhaust.The preferred embodiments that film vacuum of the present invention attaches control method may further comprise the steps:
S1: set conducting order and the time of each relay of control as required, to Programming of programmable controller.
S2: Programmable Logic Controller is according to the conducting of setup parameter pilot relay order and time, thereby controls corresponding vacuum control valve events.
In the present embodiment, Programmable Logic Controller 40 is according to exhaust order and the time of vent port 12a, the 12b of above-mentioned setting, 13c, and its corresponding relay 20a, 20b, 20c of conducting successively is to open corresponding vacuum control valve 15a, 15b, 15c.
S3: vacuum extractor exhaust.
In the present embodiment, when each R angle all equates, set the exhaust simultaneously of all vent ports.Be: when the R angle (representing with Ra, Rb, Rc respectively) of vent port 12a, 12b, the corresponding die cavity of 13c all equates, then this Programmable Logic Controller 40 pilot relay 20a, the equal conducting of 20b, 20c, thus vacuum control valve 15a, 15b, 15c all open.So described vacuum extractor 18 is bled to described vent port 12a, 12b, 13c simultaneously by described pressure accumulation tube 16.
When described R angle is unequal, control described vent port according to its corresponding R angle order from big to small exhaust successively.
Be: according to Ra, Rb, Rc order from big to small, the control vacuum control valve earlier unlatching corresponding with this Ra, Rb, Rc successively, thus the vacuum extractor that is connected with this vacuum control valve is bled to corresponding vent port.Such as: as Ra＞Rb＞Rc, then vent port 12a elder generation exhaust, then vent port 12b exhaust, last vent port 13c exhaust.
From the above, film is in being attached at the process of die cavity, and the exhaust of the vent port in the place that the R angle of die cavity is big elder generation has been avoided film because exhaust is simultaneously having the R angle to locate the gauffer that produces.And the time that above-mentioned vacuum extractor is bled to each vent port is obtained by experiment, has guaranteed the abundant exhaust of each vent port.
In addition, each vent port is an external pressure accumulation tube respectively, has guaranteed that each vent port suffered air pressure absorption affinity when carrying out exhaust equates, has reduced the fold that film produces because absorption affinity is uneven.
