Description
Technical field
The utility model relates to Die temperature control machine technology field, especially relates to the full-liquid type high temperature fortune water type mould constant temperature machine on injection machine.
Background technology
Only under stable mold temperature, injection machine just can produce high-quality product.General before injection molding operation starts, need pipeline ad hoc in the fluid flow through molds of heat to mould and die preheating.Oil and water are the liquid often adopted, and the situation that oil easily leaks, pollutes, and the cost of oil is higher and its temperature accuracy is not high, thus generally trends towards at present using water as heating working medium.Because the temperature of water under normal pressure can be seethed with excitement higher than 100 degree, so need will maintain certain pressure in relevant vessel and in circulating system.Therefore, high pressure can be formed therefore there is certain danger in heater, if pressure is excessive, certain risk can be caused to the person in heater or in the hot water process of circulation.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model proposes a kind of full-liquid type high temperature fortune water type mould constant temperature machine, its objective is and can carry out inspection to the pressure in heater and various pipeline and constant voltage, ensure safety.
In order to solve above-mentioned technical problem; the basic technical scheme that the utility model proposes is: a kind of full-liquid type high temperature fortune water type mould constant temperature machine; comprise casing; heater and water pump is provided with in described casing; the water inlet end of described water pump is communicated with water inlet pipe by the first conduit; the water side of described water pump is communicated with heater by the second conduit; described heater is by the 3rd tubes connection one pressure protector, and described heater is also respectively by an electronics relief valve and a mechanical pressure release valve communicated drainage pipe.
In full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model, described pressure protector comprises high-pressure protector and low pressure protector; One end of described 3rd conduit connects the test side of high-pressure protector, and the other end connects the bottom of heater.
In full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model, described low pressure protector is communicated with water inlet pipe by the 4th conduit.
In full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model, the water side of described water pump connects the bottom of described heater.
In full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model, described first conduit is arranged at intervals with the first check valve and the second check valve.
In full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model, the water inlet end of described water inlet pipe is connected with a filter.
The beneficial effects of the utility model are:
The technical solution of the utility model arranges a pressure protector and electronics relief valve and mechanical pressure release valve; the pressure in heater is detected by pressure protector; when pressure is higher than setting value; pressure release can be carried out by electronics relief valve or mechanical pressure release valve to the pressure in heater, ensure the safety of equipment.
Accompanying drawing explanation
Fig. 1 is the principle schematic of full-liquid type high temperature described in the utility model fortune water type mould constant temperature machine;
Fig. 2 is the structural representation of full-liquid type high temperature described in the utility model fortune water type mould constant temperature machine.
Detailed description of the invention
Be described further below with reference to accompanying drawing 1 and accompanying drawing 2 pairs of the utility model, but protection domain of the present utility model should do not limited with this.
Contrast accompanying drawing 1 and accompanying drawing 2:
Full-liquid type high temperature fortune water type mould constant temperature machine described in the utility model comprises casing 10; heater 20 and water pump 30 is provided with in this casing 10; the water inlet end 301 of described water pump 30 connects 01 logical water inlet pipe 40 by the first conduit; the water side 302 of described water pump 30 is communicated with heater 20 by the second conduit 02; described heater 20 connects a pressure protector 50 by the 3rd conduit 03, and described heater 20 is also respectively by electronics relief valve 60 and a mechanical pressure release valve 70 communicated drainage pipe 80.
Concrete, pressure protector 50 comprises high-pressure protector and low pressure protector; One end of described 3rd conduit 03 connects the test side of high-pressure protector, and the other end connects the bottom of heater 20; Described low pressure protector is communicated with water inlet pipe by the 4th conduit 04; The water side 302 of water pump 30 connects the bottom of described heater 20; Described first conduit 01 is arranged at intervals with the first check valve 05 and the second check valve 06; The water inlet end of described water inlet pipe 40 is connected with a filter 07.
Specific works procedure:
At the beginning, cold water enters into water inlet pipe 40 flow through filter 07 from cooling column after, and enters into water pump 30 from the first conduit 01, and finally enter into heater 20, meanwhile heater 20 heats the water flow to, and adds water until to filling heater 20.Because be heated to 200 DEG C, therefore, in heater 20, produce high pressure, and each heater there is a safe pressure that can bear, and in time exceeding this safe pressure, can produce danger.Therefore, high-pressure detector detects the pressure in heater 20, and when exceeding the force value of setting, electronics relief valve 60 or mechanical pressure release valve 70 will be opened, and carry out pressure release until the pressure in heater 20 reaches setting value to heater 20.Owing to arranging electronics relief valve 60 and mechanical pressure release valve 70, wherein one another one relief valve can work on when breaking down inoperable, like this just can play the effect of dual fail-safe.In addition, low pressure protector 502 detects the pressure of water inlet pipe 40.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
