Description
Technical field
The utility model relates to a kind of heater, is specifically related to a kind of injection molding machine positive temp coefficient thermal sensitive resistance electrical heater.
Background technology
Injection molding machine needs by making plastic pellet melt to the heating of head tank, and plastic particles becomes solution state and is injected in mould by ejecting mechanism by plastic cement liquid, produces various plastic parts.
Traditional plastic pellet head tank heating arrangements generally adopts common heating wire or fever tablet to make loop configuration anchor ear on charging basket, this heating wire and fever tablet are permanent resistance both invariable power, switch heater power source by the control unit of outside and realize temperature control, when temperature reaches capping, heater power-off also stops heat supply, when temperature drops to preset lower limit, heater restores electricity, and starts heating.The heater of this invariable power causes heater frequent starting, reduces heater useful life, simultaneously also not energy-conservation.
Summary of the invention
In order to solve deficiency existing in prior art, the utility model proposes a kind of injection molding machine positive temp coefficient thermal sensitive resistance electrical heater.
A kind of injection molding machine positive temp coefficient thermal sensitive resistance electrical heater, comprises three pieces of circular heaters of coaxially arranging.The utility model is sleeved on external injection machine bucket, heat treated can be carried out to injection machine bucket, guarantee carrying out smoothly of injection moulding.The utility model adopts three pieces of circular heaters of coaxially arranging, because injection machine bucket itself is longer on the one hand, circular heater can be made like this to be paved with the periphery of injection machine bucket, realize heating fully, on the other hand, circular structural design, thus make even heat be distributed in injection machine bucket circumferentially, there will not be the phenomenon of local overheating.
Described circular heater structure is identical, and described circular heater coaxially fits tightly rear formation by the heating ring that quantity is equal.Define block annular-heating circle, heat is concentrated.
Described heating ring includes electro-heat equipment, mounting bracket, fin, aluminum pipe and prepackage panel beating, described aluminum pipe is similar round structure, the bottom of described aluminum pipe is provided with breach, described fin is along the equally spaced arrangement of axis direction of aluminum pipe, described aluminum pipe is closely cooperated by the mode of reaming reducing and fin, described prepackage panel beating is sleeved on lower end and the middle part of aluminum pipe successively along the axis direction of aluminum pipe, described mounting bracket correspondence is arranged on and is on the prepackage panel beating of aluminum pipe lower end, and electro-heat equipment draws two terminals through behind aluminum pipe inside.Two terminals are linked on external power supply, electro-heat equipment can be utilized to produce heat, and utilize fin to be shed by heat in time, thus serve heat effect to injection machine bucket, guarantee carrying out smoothly of injection moulding; The utility model devises prepackage panel beating, instead of the mode of traditional reserved installation site, the panel beating of utilization prepackage simultaneously, mounting bracket are processed into by ferrous material, when expanding with heat and contract with cold, thus the coefficient of expansion unanimously can not produce friction displacement and cause abnormal sound, can not bring impact to Mould Machining.
Described electro-heat equipment is semistor heating element.The utility model adopts semistor heating element, can reach temperature automatically controlled effect, improve useful life, and in use procedure, safety is controlled, varies with temperature regulation output power thus obtains effectively energy-conservation effect.
Described mounting bracket is provided with waist type installing hole, fits tightly successively be fixed together to facilitate heating ring.
The quantity of described prepackage panel beating is no less than three, is connected with other external parts to facilitate.
The beneficial effects of the utility model are: the utility model has the advantages such as the low and heating effect of reasonable in design, manufacturing cost is good, A.T.C can be realized, in heating process, when temperature due to injection machine bucket rises, the resistance of semistor heating element can slowly become large, temperature is higher, and the larger then power of resistance is lower; When low temperature, the power of semistor heating element can reach the power of common heater 1/2nd, thus make overall heating time long, the part controlled is without the need to frequent starting, simultaneously, power during hot operation only has 1/2nd of common heater power, serves good energy-conserving action; Adopt annular-heating, injection machine bucket is heated evenly, avoids the injection moulding quality caused because local heating is uneven and go wrong.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of heating ring of the present utility model;
Fig. 2 is the I partial enlarged drawing of Fig. 1;
Schematic diagram when Fig. 3 is utility model works.
