Abstract
The invention relates to a taper type needle valve hot sprue main body structure, which comprises a hot sprue main body, and an installation seat connected with the hot sprue main body in a sleeving way, wherein the hot sprue main body is of a frustum shape; and a circular bead transition structure is arranged on a sleeve joint part of the frustum-shaped hot sprue main body and the installation seat. The scheme mainly solves the problems that in the prior art, the hot sprue main body has insufficient strength, is easy to fracture, is not suitable to be processed to be too long, and has higher cost. The taper type needle valve hot sprue main body structure is simple and practical.
Description
Technical field
The invention belongs to the TOP-TIP field, relate to the hot mouth structure on a kind of TOP-TIP, relate in particular to the hot mouth agent structure of a kind of tapering formula needle-valve.
Background technology
TOP-TIP is a kind of plastic mould parts at present commonly used, and it is with respect to common flow passage, has simplified control, molding cycle is short, economizes in raw materials, plurality of advantages such as the goods cost is low, product quality height.At present, the hot mouth that TOP-TIP is commonly used comprises hot mouth main body, and hot mouth main body outside is provided with heat-generating pipe, and inside is provided with runner, and the head of hot mouth main body is socketed with mount pad.The structure of hot mouth main body 1 is as shown in Figure 1, and itself and mount pad 2 socket places are provided with step 3, and hot mouth main body 1 is from as cylindrical structural, and step 3 places are wedge angle 4 structures.Though the hot mouth main body of this structure is being used, and still comes with some shortcomings always, mainly be that the horn structure at step 3 places plays the sharp corner insufficient strength, stress all concentrates on sharp corner, causes sharp corner tired, easily fracture.And this horn structure is higher to the material requirements of hot mouth main body, makes production cost higher.In addition, this horn structure makes the insufficient strength of hot mouth main body, thereby can not process long hot mouth main body.
Therefore, how addressing the above problem, is the content that the present invention will study.
Summary of the invention
The present invention provides a kind of tapering formula needle-valve hot mouth agent structure, and its purpose mainly is to solve hot mouth main body insufficient strength in the prior art, easy fracture, should not process long size and cost problem of higher.
For achieving the above object, the technical scheme that the present invention adopts is: the hot mouth agent structure of a kind of tapering formula needle-valve, comprise hot mouth main body, with the mount pad of hot mouth main body socket; Said hot mouth main body is a taper type, and hot mouth main body of this taper type and mount pad socket place are provided with the round-corner transition structure.
Because the utilization of present technique scheme, the present invention compared with prior art has advantage:
1, because hot mouth main body of the present invention adopts taper type; Hot mouth main body and mount pad socket place adopt tapering formula round-corner transition structure, and this structure makes that hot mouth main body intensity is better, can process longer size; And round-corner transition can not produce stress and concentrate, and hot mouth main body is difficult for rupturing.
2, the present invention makes that hot mouth main body self intensity is better owing to adopt tapering formula round-corner transition structure, thereby not high to the material requirements of processing hot mouth main body, has reduced production cost.
3, the present invention is simple in structure, practical.
Description of drawings
Accompanying drawing 1 is a hot mouth agent structure sketch map in the prior art;
Accompanying drawing 2 is used structural representation for the present invention.
In the above accompanying drawing: 1, hot mouth main body; 2, mount pad; 3, step; 4, wedge angle; 5, fillet.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
As shown in Figure 2, the hot mouth agent structure of a kind of tapering formula needle-valve, comprise hot mouth main body 1, with the mount pad 2 of hot mouth main body 1 socket; Said hot mouth main body 1 is a taper type, and the hot mouth main body 1 of this taper type is provided with fillet 5 transition structures with mount pad 2 socket places.
Hot mouth main body 1 adopts taper type; Hot mouth main body 1 adopts tapering formula fillet 5 transition structures with mount pad 2 socket places, and this structure makes that the intensity of hot mouth main body 1 is better, can process longer size; And fillet 5 transition can not produce stress and concentrate, and hot mouth main body 1 is difficult for rupturing.
Owing to adopt tapering formula round-corner transition structure, make that hot mouth main body 1 self intensity is better, thus not high to the material requirements of processing hot mouth main body 1, reduced production cost.This is simple in structure, practical.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
