Abstract
The utility model discloses a totally closed locking heating element, including totally closed metal sleeve, totally closed metal sleeve is the cylinder that a side direction is opened has the opening, the cylinder has inner wall and outer wall and connects the upper and lower both sides wall of inner wall and outer wall, inner wall, outer wall and both sides wall have constituted the closed cavity of a holding heater, be equipped with the heater in the closed cavity, the both ends of heater are close to the opening from the both sides wall stretches out, the beneficial effects of the utility model reside in that, owing to adopt totally enclosed structure, the heat of heater all gives off to totally closed metal sleeve, and then the transmission improves heat transfer efficiency for moulding plastics hot mouth.
Description
Technical field
The utility model relates to heating device technology area, relates in particular to a kind of totally-enclosed locking heating element.
Background technology
For preventing that plastic cement melt from solidifying in injection heat mouth, the injection heat mouth of existing injection mold is generally all fitted with corresponding heater, and existing heater is generally adopted the combination of metal sleeve and heating wire, and heating wire is generally exposed, heat major part is fallen apart in air, and the efficiency of heating surface is lower.
Utility model content
The utility model, for the deficiency of prior art, provides the totally-enclosed locking heating element that a kind of efficiency of heating surface is high.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of totally-enclosed locking heating element, comprise totally-enclosed metal sleeve, described totally-enclosed metal sleeve is the cylinder that a side direction has gap, described cylinder has inwall with outside and is connected inwall and the two side up and down of outer wall, described inwall, outer wall and two side have formed the enclosed cavity of accommodating heating wire, in described enclosed cavity, be provided with heating wire, stretch out near opening position from two side at the two ends of heating wire.
More specifically, the outer diameter of described cylinder is 2～4cm.
More specifically, the inner diameter of described cylinder is 1～3cm.
More specifically, the width of described gap is 0.5～1cm.
More specifically, the outer diameter of described cylinder is 3cm, and the inwall of cylinder is 2.8cm, and the width of gap is 0.5cm.
More specifically, totally-enclosed metal sleeve is stainless steel member.
The beneficial effects of the utility model are, owing to adopting totally enclosed structure, the heat of heating wire is all distributed to totally-enclosed metal sleeve, and then passes to injection heat mouth, improves heat transfer efficiency.
Brief description of the drawings
Fig. 1 is side structure schematic diagram of the present utility model.
Detailed description of the invention
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As Fig. 1, the present embodiment comprises totally-enclosed metal sleeve, described totally-enclosed metal sleeve is the cylinder 1 that a side direction has gap 13, described cylinder 1 has inwall 11 and outside 10 and is connected the two side up and down 12 of inwall 11 and outer wall 10, described inwall 11, outer wall 10 and two side 12 have formed the enclosed cavity of accommodating heating wire 2, in described enclosed cavity, be provided with heating wire 2, stretch out from two side near gap 13 at the two ends of heating wire 2.
Outer wall 10 diameters of described cylinder 1 are 3cm, and the inwall 11 of cylinder 1 is 2.8cm, and the width of gap is 0.5cm, and totally-enclosed metal sleeve is stainless steel member.
The present embodiment, owing to adopting specific size, is relatively applicable to the specific occasion of installing, and owing to having adopted totally enclosed structural design, heat transfer efficiency promotes greatly.
Although more than described detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims. Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection domain of the present utility model.
