Description of the drawings
Fig. 1：A kind of one system diagram of water-cooled die heater embodiment.
Fig. 2：A kind of water-cooled die heater embodiment two system figure.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Fig. 1 is the embodiment one of the utility model, includes return pipe 1, water pump 2, heating kettle 3 and outlet pipe 4, the return water
1 side of pipe connects 2 water inlet of water pump, and 2 water outlet of water pump connects the heating kettle 3,4 side of the outlet pipe connection
The opposite side of heating kettle 3, the return pipe 1 and outlet pipe 2 is respectively equipped with backwater joint and water outlet connector distinguishes connecting mold
Water outlet and water inlet form circulation waterway, are connected with cooling tube 7 on the return pipe 1,7 side of cooling tube with described time
1 junction of water pipe forms tie point 1, and 7 opposite side of cooling tube is equipped with warter connection, described for connecting cooling water
Shunt valve 5 is connected between return pipe 1 and outlet pipe 4, the junction of the shunt valve 5 and return pipe 1 forms tie point 2 12.
Drainpipe 6 is connected on the outlet pipe 4, drain valve 61 is in series on the drainpipe 6,
Further, the tie point 2 12 is located at 2 proximal end of water pump, and the tie point 1 is located at the water pump 2
Distally.
Further, cooling valve 71 is also in series on the cooling tube 7, in normal use, is not provided with cooling valve 71, only
One drain valve 61 of setting can realize refrigerating function simultaneously, after only increasing cooling valve 71, make control more accurate.
Further, the outlet pipe 4 is equipped with temperature sensor 8 and pressure sensor 9.
Further, the shunt valve 5 is equipped with bypass valve 51, when outlet pipe 4 or the reduction of 1 flow of return pipe, can make
Into pressure rise, when pressure sensor 9 detects that pressure is more than setting value, bypass valve 51 can automatically open, to reduce water pump
Load.
Embodiment one, during normal operation, recirculated water flow：
Backwater joint → 9 → outlet pipe of return pipe 1 → water pump, 2 → heating kettle, 3 → temperature sensor, 8 → pressure sensor 4
→ water outlet connector → mold → backwater joint, is recycled；
When the actual temperature of die heater is higher than set temperature, cooling valve 71, bypass valve 51 and drain valve 61 open simultaneously,
Cooling water is entered from warter connection in cooling tube, while the drainage joint of hot water from 6 one end of drainpipe discharges hot water, tool
Body is as follows：
Warter connection → cooling tube 7 → 3 → temperature sensor of cooling valve 71 → return pipe, 1 → water pump, 2 → heating kettle 8 →
（A part）Pressure sensor 9 → outlet pipe, 4 → drainpipe, 6 → drain valve, 61 → drainage joint；
