Description
Technical field
This utility model relates to the hydraulic circuit of large size plastic jetting-moulding device Clamping System security control.
Background technology
The hydraulic insurance circuit of existing large size plastic jetting-moulding device Clamping System security control, reach safe requirement typically by the oil that controls cutting off the main valve promoting the electro-hydraulic direction valve of folding mould, hydraulic pressure insurance energy thus the safe coefficient of injection machine itself is greatly improved.But the most sometimes can be because of situations such as a variety of causes cause that main valve blocks, make oil circuit control that the phenomenon that security insurance lost efficacy easily occur, and it is indivedual regional abroad, higher to safety equipment requirement degree, it is desirable to no matter the working connection of matched moulds valve all can be triggered and cut off in Qianmen or back door in time.
Utility model content
This utility model provides a kind of hydraulic circuit for large size plastic jetting-moulding device Clamping System security control for overcoming above-mentioned deficiency so that it is more safe and reliable.
This utility model purpose is achieved by the following technical solution.
A kind of hydraulic circuit for large size plastic jetting-moulding device Clamping System security control, including Qianmen operating direction valve, back door operating direction valve, inserted valve, shuttle valve, the inserted valve of band detection function, shuttle valve is bridged between the inserted valve of Qianmen operating direction valve, back door operating direction valve and band detection function, shuttle valve stops with Qianmen operating direction valve, the Guan Bi of the inserted valve of back door operating direction valve co-controlling band detection function, the final action controlling folding mould oil cylinder.
The inserted valve of above-mentioned band detection function provides a valve to close the detection signal put in place to controller, can effectively supervise and know that valve port closes the time put in place and the situation that puts in place, the closed feedback signal of output main valve plug is to controller, the safe class being effectively increased on equipment.
This utility model is owing to all can effectively guarantee when front safety door, rear safety door are individually opened or open that die sinking cannot be carried out with closing mould action simultaneously, and can accurately, in time, effectively stop opening mould assembling action, it is ensured that the safety of operator；And the inserted valve that band confirms detection function provides the detection function that closedown puts in place, security performance is higher.Whole hydraulic safety circuit simple in construction, easy for installation, safeguard simple, it is possible to be applied on the equipment such as the higher injection machine of safety requirements.
Accompanying drawing explanation
Fig. 1 is the hydraulic circuit schematic diagram of this utility model embodiment large size plastic jetting-moulding device Clamping System security control, and front safety door and rear safety door simultaneously close off, and the hydraulic circuit of injection machine security control is normal, and equipment normally works.
Fig. 2 is the loop diagram that safety door is opened before this utility model embodiment folding mould hydraulic circuit, opens mould assembling action and stops.
Fig. 3 is the loop diagram that safety door is opened after this utility model embodiment folding mould hydraulic circuit, opens mould assembling action and stops.
Fig. 4 is that this utility model embodiment folding front safety door of mould hydraulic circuit opens the loop diagram simultaneously opened with rear safety door, opens mould assembling action and stops.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is further described.
As shown in Figure 1, a kind of hydraulic circuit for large size plastic jetting-moulding device Clamping System security control, including Qianmen operating direction valve 1, back door operating direction valve 3, inserted valve 4, shuttle valve 5, the inserted valve 6 of band detection function, shuttle valve 5 is bridged between the inserted valve 6 of Qianmen operating direction valve 1, back door operating direction valve 3 and band detection function, shuttle valve 6 and Qianmen operating direction valve, the Guan Bi of the inserted valve of back door operating direction valve co-controlling band detection function, the action controlling folding mould oil cylinder stops.
Above-mentioned hydraulic circuit is unclamped by next coming in order at front safety door touch panel, rear safety door touch panel unclamps, front safety door touch panel back door touch panel all unclamps, safety door touch panel is all depressed four kinds of operating modes and is described after front safety door touch panel.
Front safety door touch panel unclamps, in the case of rear safety door touch panel pressing: as shown in Figure 2, the high voltage control oil of system is communicated with B chamber by the P chamber of Qianmen operating direction valve 1, epicoele through shuttle valve 5 with the inserted valve 6 of band detection function is connected, because cavity area is more than lower cavity area on inserted valve, band is detected inserted valve 6 pressing of function and closes by pressure oil.While inserted valve 6 pressing closing motion completes, the test point of the inserted valve 6 of band detection function provides a shutdown signal to controller, and controller cutting system oil-feed, the most now injection machine just cannot be carried out out mould assembling action.
Rear safety door touch panel unclamps, in the case of front safety door touch panel pressing: as shown in Figure 3, the high voltage control oil of system is communicated with B chamber by the P chamber of back door operating direction valve 3, epicoele through shuttle valve 5 with the inserted valve 6 of band detection function is connected, because cavity area is more than lower cavity area on inserted valve, band is detected inserted valve 6 pressing of function and closes by pressure oil.While inserted valve 6 pressing closing motion completes, the test point of the inserted valve 6 of band detection function provides a shutdown signal to controller, controller cutting system oil-feed.The most now machine just cannot be carried out out mould assembling action.
In the case of front safety door touch panel and rear safety door touch panel all unclamp: as shown in Figure 4, the high voltage control oil of system is communicated with B chamber by the P chamber of Qianmen operating direction valve 1；The high voltage control oil of system is communicated with B chamber by the P chamber of back door operating direction valve 3, two-way high voltage control oil is connected through the epicoele of shuttle valve 5 with the inserted valve 6 of band detection function, because cavity area is more than lower cavity area on inserted valve, band is detected inserted valve 6 pressing of function and closes by pressure oil.While inserted valve 6 pressing closing motion completes, the test point of the inserted valve 6 of band detection function provides a shutdown signal to controller.Cutting system oil-feed under this operating mode.The most now machine just cannot be carried out out mould assembling action.
Front safety door touch panel with in the case of the rear equal pressing of safety door touch panel: as it is shown in figure 1, the high voltage control oil of system is communicated with the A chamber of closing by the P chamber of Qianmen operating direction valve 1；The high voltage control oil of system is communicated with the A chamber of closing by the P chamber of back door operating direction valve 3, and shuttle valve about 5 two chamber is all without high voltage control oil.The epicoele of the inserted valve 6 of band detection function communicates with oil return line, and band is detected the inserted valve 6 of function and backs down by system oil-feed.Under normal circumstances, switching molding action is operating normally remaining equipment of injection machine equipment.
