Description
Technical field
The utility model relates to the Electrical Control Technology field, the controller of especially a kind of plastic mould cool cycles water route solenoid directional control valve.
Background technique
The injection molding process of working of plastics generally will comprise filling, pressurize, cooling and demoulding four-stage, and this four-stage is directly determining the Forming Quality of goods, and this four-stage is a complete and continuous process.Since time of cooling stage generally to account for whole molding cycle 70%-80%, so will directly influence the length in plastic product forming cycle and the size of output cool time; The time that effectively shortens cooling helps improving injection moulding efficient; The injection mould major part of existing higher-end all adopts water cycle to cool off to shorten cool time; And the water cycle water route generally need be switched cooling water through solenoid directional control valve and fed mould and circulate or cut off cooling water and get in the mould; The action of existing solenoid directional control valve will be controlled through PLC or single-chip microcomputer mostly; But the input cost of PLC or single-chip microcomputer is bigger, and the operation easier of its programming is also higher when changing process parameter, and common operator are difficult to accomplish.
The model utility content
The technical problem that the utility model will solve provides the controller of a kind of plastic mould cool cycles water route solenoid directional control valve, and cost is low, and is simple to operate, uses convenient and reliable.
For achieving the above object; The technological scheme of the utility model is: the controller of a kind of plastic mould cool cycles water route solenoid directional control valve; Comprise near switch, time-delay engage relay, time-delay and break off relay; The main circuit of time-delay engage relay and time-delay disconnection relay is connected in series the one of which end each other and is connected with a pin of electromagnetic switch valve coil through an end, its other end that is connected single phase alternating current power supply near switch, and another pin of electromagnetic switch valve coil connects the other end of single phase alternating current power supply; The control circuit one of which utmost point connected with each other of time-delay engage relay and time-delay disconnection relay is also through an end that is connected single phase alternating current power supply near switch, the other end that its another utmost point connects single phase alternating current power supply; Describedly connect when the mould matched moulds, when the mould die sinking, break off near switch.
Preferred described is magnetic approach switch near switch, convenient installation near switch.
Further improve, be provided with safety fuse cutout between the said end, prevent that overcurrent from damaging the time-delay engage relay and breaking off relay with time-delay near switch and single phase alternating current power supply.
The utility model is through realizing the control of cycle time of plastic mould cool cycles water route cooling water near the combination of switch with time-delay engage relay and time-delay disconnection relay; The control part is less and cost is lower; Change process parameter simultaneously and need adjust cooling water during cycle time, as long as adjustment time-delay engage relay breaks off the delay time of relay with delaying time, the common laborer also can operate; Therefore simple to operate, use convenient and reliable.
Description of drawings
Fig. 1 is the utility model principle schematic.
Embodiment
Below in conjunction with accompanying drawing and concrete mode of execution the utility model is done further explain.
Shown in Figure 1; The controller of a kind of plastic mould cool cycles water route solenoid directional control valve; Comprise near switch 1, time-delay engage relay 2, time-delay and break off relay 3; The main circuit of time-delay engage relay 2 and time-delay disconnection relay 3 is connected in series the one of which end each other and is connected with a pin of solenoid directional control valve 4 coils through an end, its other end that is connected single-phase 220V ac power supply near switch 1, and another pin of solenoid directional control valve 4 coils connects the other end of single-phase 220V ac power supply; The control circuit one of which utmost point connected with each other of time-delay engage relay 2 and time-delay disconnection relay 3 is also through an end that is connected single-phase 220V ac power supply near switch 1, the other end that its another utmost point connects single-phase 220V ac power supply; Can connect when the position makes mould 5 die sinkings near being provided with of switch 1, when the mould matched moulds, break off.
Preferred described is magnetic approach switch near switch 1.
Between a end, also be connected with safety fuse cutout 6 near switch 1 and single-phase 220V ac power supply.
The working principle of the utility model is following: be the time set of the time-delay of time-delay engage relay 2 the time sum of filling stage and packing stage earlier, the time set that breaks off time-delay the time-delay of relay 3 is the time sum of filling stage, packing stage and cooling stage, when mould 5 die sinkings, connects near switch 1; Time-delay engage relay 2 is connected trigger simultaneously with the control circuit that relay 3 is broken off in time-delay; The delay time of time-delay engage relay 2 is connected main circuit to the back, this moment solenoid directional control valve 4 coil electricities, solenoid directional control valve 4 actions feed in the mould 5 cooling water and begin to cool down; After arriving cool time; The delay time that relay 3 is broken off in time-delay this moment also arrives, and time-delay is broken off relay 3 and broken off main circuit, solenoid directional control valve 4 coil blackouts; Solenoid directional control valve 4 moves return again; Cut off the cooling water that feeds mould 5, but mould 5 die sinkings are broken off the next circulation of entering near switch 1 after the die sinking.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
