Abstract
The invention relates to a mold temperature controller, specifically to an automatic exhaust type mold temperature controller. The automatic exhaust type mold temperature controller is provided with a shell; the interior of the shell is provided with a heating bucket with a heater, a water pump and a draining solenoid valve; the water outlet of the heating bucket is connected with a water outlet pipe on the shell through a conduit, a water inlet pipe on the shell is connected with the water inlet of the water pump through a conduit, and the water outlet of the water pump is connected with the water inlet of the heating bucket through a conduit; the water outlet pipe is provided with a temperature sensor, and the heating bucket is provided with a water level inductor and an overheating preventing inductor. The automatic exhaust type mold temperature controller is characterized in that the heating bucket is provided with an automatic exhaust valve. The water pump works and allows water to circulate in the mold temperature controller and to be heated in the heating bucket when the mold temperature controller works; when the temperature rises to more than 100 DEG C, internal pressure in the mold temperature controller increases, the automatic exhaust valve works, gas in the mold temperature controller is discharged, and the mold temperature controller can be started and works immediately. The automatic exhaust type mold temperature controller has the following advantages: 1, the mold temperature controller does not need to be started for draining so as to realize exhausting; 2, the temperature of the controller is not influenced during exhausting; and 3, pressure is stable when the controller reaches a set temperature.
Description
Technical field
The present invention relates to warm mould machine, specifically the automatic vent type die heater of a kind of easy to operate, working stability, energy-conserving and environment-protective.
Background technology
Existing temperature mould machine is start drainage type die heater, generally be provided with housing, in housing, be provided with the heating bucket with heater, water pump and drain solenoid valve, the delivery port of heating bucket is connected with the outlet pipe on housing through conduit, water inlet pipe on housing is connected with the water inlet of water pump through conduit, the outlet pipe of water pump is connected with the water inlet of heating bucket with conduit, outlet pipe is provided with temperature sensor, heating bucket is provided with water level sensor and prevents excessive temperature sensor, Auto-drainage after start, gas in system is discharged, water enters system from pipeline again, magnetic valve is opened a period of time, internal system gas is discharged, water is full of system, pump operation, machine work, internal system temperature is heated by heating tube, after temperature surpasses 100 ℃, can produce a small amount of gas, there is internal system, when air pressure too high, electromagnetic valve is opened Exhaust Gas, reduce system pressure, its less than one is that each start needs draining a period of time, hinder and use, the 2nd, gas can not fully be discharged, and retains in addition the possibility of system, the 3rd, a part of water is taken in each exhaust meeting out of, covers water at low temperature simultaneously, and temperature can not be stablized, the 4th, hyperbar can be that system produces backflow phenomenon.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of automatic vent type die heater is provided.
The present invention can reach by following measure:
A kind of automatic vent type die heater, be provided with housing, in housing, be provided with heating bucket, water pump and drain solenoid valve with heater, the delivery port of heating bucket is connected with the outlet pipe on housing through conduit, water inlet pipe on housing is connected with pump intake through conduit, the delivery port of water pump is connected with the water inlet of heating bucket with conduit, outlet pipe is provided with temperature sensor, heating bucket is provided with water level sensor and prevents excessive temperature sensor, it is characterized in that heating bucket and is provided with automatic exhaust steam valve.
When the present invention works, pump working circulates water in system, in heating bucket, heat, when temperature rises to more than 100 ℃, internal system pressure increases, automatic exhaust steam valve work, gas in system is discharged, when temperature maybe needs to lower the temperature higher than design temperature, drain solenoid valve is opened, discharge hot water and cold water is supplemented into by water inlet pipe, machine cycle operation like this, utilize automatic exhaust steam valve to discharge gas in system, system can be started shooting and be worked immediately, without pressure switch, control exhaust, or carry out manual exhaust, an air bleeding valve not draining of exhaust, energy-conserving and environment-protective, advantageous effect one is that exhaust is carried out in the machine draining of need not starting shooting, the 2nd, during exhaust, do not affect system temperature, the 3rd, when system reaches design temperature, pressure stability, does not need to increase check valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of automatic vent type die heater, be provided with housing 1, in housing, be provided with the heating bucket 2 with heater, water pump 3 and drain solenoid valve 4, the delivery port of heating bucket 2 is connected with the outlet pipe 5 on housing through conduit, water inlet pipe 6 on housing is connected with water pump 3 water inlets through conduit, the delivery port of water pump 3 is connected with the water inlet of heating bucket 2 with conduit, outlet pipe 5 is provided with temperature sensor 7, heating bucket 2 is provided with water level sensor 8 and prevents excessive temperature sensor 9, the structure of above-mentioned kind of part and the mutual downlink connection relation between them are same as the prior art, this does not repeat, the invention is characterized in that heating bucket 2 is provided with automatic exhaust steam valve 10, automatic exhaust steam valve 10 structures and the mutual downlink connection relation between them are same as the prior art, this does not repeat, when the present invention works, pump working circulates water in system, in heating bucket, heat, when temperature rises to more than 100 ℃, internal system pressure increases, automatic exhaust steam valve work, gas in system is discharged, when temperature maybe needs to lower the temperature higher than design temperature, drain solenoid valve is opened, discharge hot water and cold water is supplemented into by water inlet pipe, machine cycle operation like this, utilize automatic exhaust steam valve to discharge gas in system, system can be started shooting and be worked immediately, without pressure switch, control exhaust, or carry out manual exhaust, an air bleeding valve not draining of exhaust, energy-conserving and environment-protective, advantageous effect one is that exhaust is carried out in the machine draining of need not starting shooting, the 2nd, during exhaust, do not affect system temperature, the 3rd, when system reaches design temperature, pressure stability.
