Abstract
A high-strength hot nozzle flow guide sleeve is composed of a round table and a frustum. A communicated runner is arranged in the center of the round table and the frustum. A transition portion is arranged at the tail end of the frustum to be connected with the round table. The transition portion is formed by connecting a large R corner and an inclined side, wherein one end of the large R corner is connected with the tail end of the frustum, and one end of the inclined side is connected with the round table. By means of the structure improvement, the high-strength hot nozzle flow guide sleeve effectively avoids the problem that the flow guide sleeve cracks due to stress concentration, prolongs service life and avoids material accumulation, overflowing and carbonization.
Description
Technical field
The invention belongs to the TOP-TIP field, relate to a kind of high-strength hot mouth water conservancy diversion cover that TOP-TIP is used.
Background technology
The hot mouth structure of high strength water conservancy diversion cover.The hot mouth structure of said band water conservancy diversion cover promptly is: hot mouth fore-end carries a water conservancy diversion cover, refills to be fitted on the mold integral.TOP-TIP like needle valve; Owing to be provided with the water conservancy diversion cover, its needle just can directly not contact with the cast gate of mould, and the injection moulding sizing material is to have acidity or corrosive a bit; Then this water conservancy diversion cover just can effectively be protected the needle and the gate portions of mould, so that increase the service life of mould.
At present, hot mouth water conservancy diversion cover commonly used is as shown in Figure 1, and water conservancy diversion cover 1 is made up of round platform 2 and frustum 3, and said round platform 2 is provided with the runner 4 that is communicated with the center of frustum 3; See that on the cross section end that said frustum 3 contacts with round platform 2 is provided with 5 transition of little R angle, this little R angle 5 is merely 0.5 °; The wall thickness of this R angle transition position only has 2.9mm, and in use, stress concentrates on this R angle transition position easily; Because wall thickness is thinner, insufficient strength often makes this water conservancy diversion cover break easily here; Service life is shorter.In addition, because this R angle transition position is the dead angle, overflow herein easy buildup of clout and carbonization.
Summary of the invention
In order to address the above problem, the present invention provides a kind of high-strength hot mouth water conservancy diversion cover, through the improvement of structure, has effectively avoided stress to concentrate and the problem of fracture, has prolonged service life, and has avoided the problem of long-pending flash, carbonization.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of high-strength hot mouth water conservancy diversion cover, and this water conservancy diversion cover is made up of round platform and frustum, and said round platform is provided with the runner that is communicated with the center of frustum; On the cross section, the end of said frustum is provided with transition position and is connected with round platform; Said transition position is connected to form by big R angle and hypotenuse, and an end at wherein big R angle links to each other with the end of frustum, and an end of said hypotenuse links to each other with round platform.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said big R angle is 3 °;
2, in the such scheme, the wall thickness of said transition position is 3.71mm;
3, in the such scheme, said hypotenuse refers to the limit that a frustum is seen on the cross section.
Because the utilization of present technique scheme, the present invention compared with prior art has advantage:
1, because the employing of structure of the present invention; The end of frustum is connected with round platform through transition position, and this transition position sees it is to be connected to form by a hypotenuse and a big R angle on the cross section, and this structure makes the wall thickness of transition position thicken; Its intensity is also strengthened; Concentrate thereby efficiently solve, and the problem of fracture takes place easily, the service life of the product of prolongation in the transition position stress;
2, because the present invention adopts hypotenuse to strengthen the R corner structure at the transition position of frustum and round platform, make this place not have the dead angle, thereby make that the flash at this place can be taken away smoothly, avoided buildup, carbonization phenomenon to occur;
3, the present invention is simple in structure, practical, easy to process, and production cost is low.
Description of drawings
Accompanying drawing 1 is a prior art water conservancy diversion nested structure sketch map;
Accompanying drawing 2 water conservancy diversion nested structure sketch mapes of the present invention.
In the above accompanying drawing: 1, water conservancy diversion cover; 2, round platform; 3, frustum; 4, runner; 5, little R angle; 6, big R angle; 7, hypotenuse; 8 transition positions.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
As shown in Figure 2, a kind of high-strength hot mouth water conservancy diversion cover, this water conservancy diversion cover 1 is made up of round platform 2 and frustum 3, and said round platform 2 is provided with the runner 4 that is communicated with the center of frustum 3, and this is characterized in that: on the cross section, the end of said frustum 3 is provided with transition position 8 and is connected with round platform 2; Said transition position 8 is connected to form by big R angle 6 and hypotenuse 7, and an end at wherein big R angle 6 links to each other with the end of frustum 3, and an end of said hypotenuse 7 links to each other with round platform 2.Said big R angle 6 is 3 °.The wall thickness of said transition position 8 is 3.71mm.
Because the end of frustum 3 is connected with round platform 2 through transition position 8; This transition position 8 sees it is to be connected to form by a hypotenuse 7 and a big R angle 6 on the cross section; This structure makes the wall thickness of transition position 8 thicken to 3.71mm, and its intensity is also strengthened, and concentrates thereby efficiently solve in transition position 8 stress; And the easy problem that fracture takes place, the service life of the product of prolongation.And owing to adopt hypotenuse 7 to strengthen the structure at R angle 6, make this place not have the dead angle, thereby make that the flash at this place can be taken away smoothly, avoided buildup, carbonization phenomenon to occur at the transition position 8 of frustum 3 and round platform 2.
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.
