Abstract
The invention discloses a stepped heating flow channel assembly which comprises a flow channel main body and a heating sleeve, wherein the heating sleeve is arranged on the outer side of the flow channel main body; a fixing part and a feeding hole are arranged at one end of the flow channel main body; a discharging hole is formed in the other end of the flow channel main body; a conveying channel is formed in the middle of a flow channel column body; the feeding hole, the conveying channel and the discharging hole are communicated in sequence; a fixing hole is formed in the fixing part; a stepped boss part is arranged in a position, corresponding to the feeding hole, on the outer side of the flow channel main body; the heating sleeve is provided with an avoidance part in a position corresponding to the boss part. According to the stepped heating flow channel assembly, the boss part is arranged on the outer side of the flow channel main body, so that the wall thickness of the position, corresponding to the feeding hole, of the flow channel main body is increased, the overall strength is enhanced, the flow channel main body is not easily broken, and the service life is prolonged; the heating sleeve is provided with the avoidance part in the position corresponding to the boss part, so that the total radial size of a combination of the flow channel main body and the heating sleeve remains unchanged and the overall structure of the assembly cannot be influenced.
Description
Technical field
The present invention relates to a kind of assembly of TOP-TIP, particularly a kind of intensity staged high, long service life heats flow channel component, belongs to TOP-TIP component technology field.
Background technology
Existing heating flow channel component, the lateral wall of runner main body is long straight shape, and the endoporus of heating jacket is straight-through shape, but because the charging aperture of runner main body need to be arranged to the conical surface, therefore, runner main body is thinner at the wall thickness at charging aperture place, insufficient strength, service time long easy fracture.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed that a kind of intensity is high, the staged of long service life heating flow channel component.
Technical solution of the present invention is achieved in that a kind of staged heating flow channel component, comprises runner main body and heating jacket; Described heating jacket is arranged on the outside portion of runner main body; One end of described runner main body is provided with fixed part and charging aperture; The other end of described runner main body is provided with discharging opening; The middle part of described runner cylinder is provided with away material passage; Described charging aperture, walk to expect that passage and discharging opening are communicated with successively; On described fixed part, be provided with fixing hole; The outside portion of described runner main body, is provided with stair-stepping lug boss on the position of corresponding charging aperture; Described heating jacket is provided with at respective protrusions portion place the portion of dodging.
Preferably, described discharging opening and walk to expect to be provided with between passage transition passage; The diameter of described transition passage is less than away the diameter of material passage.
Preferably, described in, walk to expect by slope, to be connected between passage and transition passage.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Staged heating flow channel component of the present invention, the lug boss in the outside of runner main body increases the wall thickness at the corresponding charging aperture of runner main body place, and bulk strength increases, and easy fracture, has not increased service life; Heating jacket respective protrusions portion place is provided with the portion of dodging, and makes total radial dimension of runner main body and heating jacket combination constant, does not affect the overall structure of assembly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the cutaway view of staged heating flow channel component of the present invention;
Wherein: 1, runner main body; 2, heating jacket; 3, fixed part; 4, charging aperture; 5, discharging opening; 6, walk to expect passage; 7, fixing hole; 8, lug boss; 9, transition passage.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As shown in Figure 1, a kind of staged heating flow channel component of the present invention, comprises runner main body 1 and heating jacket 2; Described heating jacket 2 is arranged on the outside portion of runner main body 1; One end of described runner main body 1 is provided with fixed part 3 and charging aperture 4; The other end of described runner main body 1 is provided with discharging opening 5; The middle part of described runner cylinder 1 is provided with away material passage 6; Described discharging opening 5 and walk to expect to be provided with between passage 6 transition passage 9; The diameter of described transition passage 9 is less than away the diameter of material passage 6; Describedly walk to expect by slope, to be connected between passage 6 and transition passage 9; Described charging aperture 4, walk to expect that passage 6, transition passage 9 and discharging opening 5 are communicated with successively; On described fixed part 3, be provided with fixing hole 7; The outside portion of described runner main body 1, is provided with stair-stepping lug boss 8 on the position of corresponding charging aperture 4; Described heating jacket 2 is provided with at respective protrusions portion 8 places the portion of dodging.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The staged heating flow channel component of present embodiment, the lug boss 8 in the outside of runner main body 1 increases the wall thickness at the corresponding charging aperture of runner main body 14 places, and bulk strength increases, and easy fracture, has not increased service life; Heating jacket 2 respective protrusions portion 8 places are provided with the portion of dodging, and make runner main body 1 constant with total radial dimension of heating jacket 2 combinations, do not affect the overall structure of assembly; Walk to expect the stepped setting of passage 6 and transition passage 9, the flow of material passage 6 is increased, product is easily beaten full.
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.
