Abstract
The invention discloses a hot nozzle main body including a hot nozzle body, a groove and heating wires. The groove is helically arranged on the outer periphery of the hot nozzle body, and the groove is internally wound with the heating wire; the hot nozzle body comprises a small-diameter portion and a large-diameter portion; the rear end of the small-diameter portion is arranged on the front end of the large-diameter portion; the length of the small-diameter portion is at least 4/5 that of the hot nozzle; a portion close to the rear end of the small-diameter portion is additionally provided with an encryption groove, the density of the encryption groove is at least 2.5 circle/cm, and the encryption groove is internally wound with the heating wire. The design can reduce a difference between two-end temperatures and a middle part temperature of the hot nozzle body, improves the problem that non-smooth glue output is generated due to the non-uniform hot nozzle internal temperatures; and at the same time, the axial distance of the small-diameter portion at the front end of the hot nozzle body is lengthened, so that the temperature-rising rate of the hot nozzle can be accelerated, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of programming rate fast, have a narrow range of temperature, effectively improve the have some setbacks hot mouth main body of problem of plastic emitting.
Background technology
TOP-TIP is the important component part in injection mold production equipment, utilizes heating and temperature controlled principle, makes material in the inner molten condition that keeps of runner of mould, is accompanied by the development of die industry, and TOP-TIP is also growing.A kind of hot mouth main body in currently available technology in TOP-TIP, as shown in Figure 1, a kind of groove number of turns of hot mouth body 1 excircle zone line is less, density is 2.5 circles/10cm, the number of turns that is correspondingly arranged on the heater strip in groove 2 is also fewer, cause two ends and the larger temperature difference of middle existence of hot mouth main body, the temperature difference even can reach 100 degree, the fused materials inequality of being heated in hot mouth, affect greatly plastic emitting effect, and the length of the hot mouth body rear end heavy caliber part B section of prior art is relatively long, length accounts for 2/5 of hot mouth body, the programming rate of hot mouth has slowed down.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: a kind of programming rate is fast, has a narrow range of temperature, and effectively improves the have some setbacks hot mouth main body of problem of plastic emitting.
Technical solution of the present invention is achieved in that a kind of hot mouth main body, comprises hot mouth body, groove, heater strip; Described groove helically is arranged on hot mouth body excircle, in described groove, is wound with heater strip; Described hot mouth body comprises small-bore part and heavy caliber part; The rear end of described small-bore part is arranged on the front end of heavy caliber part; The length of described small-bore part is at least 4/5 of hot mouth length; In described small-bore part, near rear end, set up the groove of encryption, groove density is at least 2.5 circles/cm, is wound around heater strip in the groove of described encryption.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of hot mouth main body of the present invention, the winding number of turns of hot mouth body middle part heater strip is increased, can reduce the temperature difference of hot mouth main body two ends and middle part, guarantee that hot mouth internal temperature is even, the axial distance of the small-bore part of described hot mouth body front end is lengthened simultaneously, can improve the programming rate of hot mouth.Design of the present invention not only can be increased work efficiency, and can also improve the problem having some setbacks due to the uneven plastic emitting producing of hot mouth internal temperature.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of a kind of hot mouth main body in prior art;
Accompanying drawing 2 is the schematic diagram of a kind of hot mouth main body of the present invention;
Accompanying drawing 3 is for being provided with the schematic diagram of heater strip in a kind of hot mouth main body of the present invention;
Wherein: 1, hot mouth body; 2, groove; 3, heater strip; 4, the groove of encrypting; A, small-bore part; B, heavy caliber part.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 2,3 is a kind of hot mouth main body of the present invention, comprises hot mouth body 1, groove 2, heater strip 3; Described groove 2 helicallies are arranged on hot mouth body 1 excircle, in described groove 2, are wound with heater strip 3; Described hot mouth body 1 comprises small-bore part A section and heavy caliber part B section; The rear end of described small-bore part A section is arranged on the front end of heavy caliber part B section; The length of described small-bore part is at least 4/5 of hot mouth length; In described small-bore part A section, near rear end, set up the groove of encryption, groove density is at least 2.5 circles/cm, the interior winding heater strip 3 of groove 4 of described encryption.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of hot mouth main body of the present invention, the winding number of turns of hot mouth body middle part heater strip is increased, can reduce the temperature difference of hot mouth main body two ends and middle part, guarantee that hot mouth internal temperature is even, the axial distance of the small-bore part of described hot mouth body front end is lengthened simultaneously, can improve the programming rate of hot mouth.Design of the present invention not only can be increased work efficiency, and can also improve the problem having some setbacks due to the uneven plastic emitting producing of hot mouth internal temperature.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
