Abstract
A cooling water flow monitoring loop for an injection moulding machine comprises an external cooling water system, an electromagnetic valve, a flow meter, an injection moulding machine controller and an injection moulding machine cooling water loop. A cooling water inlet of the external cooling water system is connected with the injection moulding machine cooling water loop after being connected with the electromagnetic valve and the flow meter, an outlet of the injection moulding machine cooling water loop is connected with a water outlet of the external cooling water system, the flow meter is used for feeding real-time flow to the injection moulding machine controller, and the injection moulding machine controller is used for controlling on and off of the electromagnetic valve by monitoring temperature and flow of cooling water passing through the flow meter. Cooling water flow and faults of the electromagnetic valve of the cooling water loop can be accurately monitored by the aid of the flow meter monitoring the cooling water loop, optimum effect of the cooling water loop can be guaranteed, and adverse influences to an injection moulding machine system caused by the faults of the cooling water loop can be eliminated.
Description
Technical field
The utility model relates to the chilled(cooling) water return (CWR) of injection machine.
Background technology
At present, the water cooling of injection machine generally adopts factory's water quench or uses the cooling-water machine cooling, and the flow of cooling water is monitoring automatically not.
Because the instability of plant water supply system or the instability that the system failure will cause the injection machine cooling water flow, if flow is excessive will to cause the cooling system supercooling, temperature is low excessively, forms condensation, thereby causes electrical short-circuit.If flow is low excessively, cooling system efficient reduces, and will influence the serviceability and the service life of injection machine.
Simultaneously,, thereby reduce cooling water flow, influence cooling effectiveness owing to injection machine cooling water system long-play or water quality reason cause loop fouling or obstruction easily.
In addition, in the time of can not switch if the cooling water magnetic valve hinders for some reason, system can not detect fault, and the chilled(cooling) water return (CWR) is out of hand, can't reach the cooling effect of injection machine.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of cooling water flow monitoring loop simple, that reliability is high, cost is low of realizing is provided for the above-mentioned defective that overcomes prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Injection machine cooling water flow monitoring loop, comprise external refrigeration water system, magnetic valve, flowmeter, controller of plastic injection molding, injection machine chilled(cooling) water return (CWR), the cooling water inlet of external refrigeration water system connects injection machine chilled(cooling) water return (CWR) import after connecting magnetic valve, flowmeter, the outlet of injection machine chilled(cooling) water return (CWR) links to each other with the delivery port of external refrigeration water system, flowmeter feeds back to controller of plastic injection molding with real-time traffic, and controller of plastic injection molding is by removing to control the switch of magnetic valve to the monitoring of the temperature of the cooling water by flowmeter and flow.
Compared with prior art, advantage of the present utility model is:
Controller of plastic injection molding is by the monitoring of flowmeter to the chilled(cooling) water return (CWR), can monitor the fault of the flow and the chilled(cooling) water return (CWR) magnetic valve of cooling water exactly, ensure the optimum efficiency of chilled(cooling) water return (CWR), eliminated owing to the adverse effect of chilled(cooling) water return (CWR) fault to injection machine system.
The utility model is realized simple, feature richness, and cost is lower, has obtained significant effect in actual applications.
Description of drawings
Fig. 1 is the principle schematic of the utility model embodiment.
The specific embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, cooling water advances to connect magnetic valve 1 water inlet, magnetic valve 1 delivery port enters injection machine chilled(cooling) water return (CWR) 4 after by flowmeter 3, injection machine chilled(cooling) water return (CWR) 4 enters cooling water outlet, flowmeter 3 feeds back to controller 2 with real-time traffic, controller 2 is controlled the switch of magnetic valve 1 by the monitoring to temperature and flow.
In the above-mentioned loop, controller of plastic injection molding 2 is by judging to the monitoring of flowmeter 3 whether the chilled(cooling) water return (CWR) flow is normal.If exceed the setting range of controller of plastic injection molding 2, then controller of plastic injection molding 2 is reported to the police.Simultaneously, whether controller of plastic injection molding 2 is judged by the logic to flowmeter 3 and magnetic valve 1, is monitored magnetic valve 1 and break down.Be the pass signal if controller of plastic injection molding 2 is exported to magnetic valve, and flowmeter 3 still has the flow feedback of certain limit within a certain period of time, then controller of plastic injection molding 2 is reported to the police.
