Description
Technical field
The utility model relates to a kind of mechanical temperature controlling instruments, relates in particular to a kind of mold temperature regulating system.
Background technology
Mould generally need be heated to certain temperature when work, to prevent the product distortion, improve the shaping efficiency of product, reduces the generation of defective products.Have now die heater is adopted in the adjusting of mold temperature usually.
Die heater comprises control circuit, heater and pump, and heater is the inner closed container that is provided with heater element, and connects into closed circuit with pump with by extending the hot switching path that pipeline is connected in the mould.By heating system water is directly heated, and be pumped on the mould, thereby reach the purpose that heats and control mold temperature by the water of the pump in the die heater with heating.
Patent CN201685425U discloses a kind of ability of swimming die heater, comprise water tank, heater, water inlet pipe, outlet pipe and pressure switch, heater is installed in the described water tank, on the inwall of described water tank, pressure switch is installed, outer wall at described water tank is provided with water inlet, delivery port and hot water outlet, one end of described outlet pipe is connected with delivery port, one end of described water inlet pipe links to each other with water inlet, the other end at described water inlet pipe is equipped with a filter, in the side of described filter near water tank, water flow switch is installed, in the side of water flow switch near water tank, be provided with a bypass pipe, an end of described bypass pipe is installed on the water inlet pipe, the other end is installed on the outlet pipe, and described water flow switch is connected with water tank inside by water inlet pipe.This die heater is after using, and ponding can not get cleaning in the mould, and there are the following problems: mould is got rusty; Mould has ponding in the mould after use, easily produce incrustation scale the mould water pipe is stopped up; Ponding is arranged in the mould, and during the dismounting pipeline, ponding can flow to injection machine or ground; Ponding water temperature in the mould is higher, and ponding flows out or is ejected into the people during dismounting, easily scalds.
Because the ponding water temperature in the mould is higher, more during mold exchange, mold temperatures such as needs are changed after descending again, have prolonged the time of replacing like this at needs, and production efficiency is lower.
The utility model content
For addressing the above problem, the utility model provides a kind of mold temperature regulating system, more during mold exchange, can remove the ponding in the mould at needs fast, need not wait until the mould cooling just can be in time mold exchange more.
For achieving the above object, mold temperature regulating system of the present utility model, comprise die heater, be connected with water injection pipe and return pipe between described die heater and the mould, be respectively arranged with Water filling valve and backwater valve on described water injection pipe and the return pipe, described water injection pipe is provided with the gas injection tube that can connect air compressor, described gas injection tube places between described Water filling valve and the described mould, described return pipe is provided with drainpipe, described drainpipe places between described backwater valve and the described mould, is respectively equipped with gas injection control valve and draining control valve on described gas injection tube and the described drainpipe.
Described Water filling valve, backwater valve, gas injection control valve and draining control valve are magnetic valve.
Adopt mold temperature regulating system of the present utility model, when mold exchange more, can purge the ponding in the mould earlier, prevent that mould from getting rusty and water pipe stops up, effectively prolong the service life of mould, can avoid the hot water in the pipe to scald the people simultaneously, improved the more security of mold exchange.Owing to when the ponding in the mould is purged, can lower the temperature to mould, and do not need to change again after mould is lowered the temperature naturally by the time, shortened the activity duration of die change, improved production efficiency, particularly carry out many variety production need carry out frequently more mold exchange the time, can enhance productivity greatly.
Description of drawings
Fig. 1 is the schematic diagram of mold temperature regulating system of the present utility model.
The specific embodiment
As shown in Figure 1, mold temperature regulating system of the present utility model comprises die heater 1, is provided with water pump 101 and heater 102 in the die heater 1 and is respectively applied for the power that water circulation is provided and is used for recirculated water is heated.Be connected with water injection pipe 2 and return pipe 3 between die heater 1 and the mould 10, the hot water line of die heater 1 and mould 10 inside links together into water circulation channel by water injection pipe 2 with return pipe 3, the water of carrying by water pump 101 by heater 102 heating after, enter into mould 10 by water injection pipe 2, get back to die heater 1 via return pipe 3 then.Be respectively arranged with Water filling valve 21 and backwater valve 31 on described water injection pipe 2 and the return pipe 3, be used for when needs are regulated temperature to mould 10, opening, and when needs stop that mould 10 carried out adjustment, close.
Described water injection pipe 2 is provided with the gas injection tube 4 that can connect air compressor 6, and described gas injection tube 4 places between described Water filling valve 21 and the described mould 10; Described return pipe 3 is provided with drainpipe 5, and described drainpipe 5 places between described backwater valve 31 and the described mould 10.Described gas injection tube 4 is used for to mould 10 injecting compressed airs, dries up the ponding in the mould 10, and described drainpipe 5 is used for discharging the ponding of mould 10, and the ponding of discharge can be discharged to the storage tank 52 of drainpipe 5 belows.
Be respectively equipped with gas injection control valve 41 and draining control valve 51 on described gas injection tube 4 and the described drainpipe 5.
