Abstract
The utility model relates to a hot runner mold technical field, in particular to an inner hot tip grating structure of a hot runner mold. The inner hot tip grating structure is a hollow path and has a complete molding protruding part at the outlet. Between the protruding part and the side walls of the hot sprue outlet are formed runner holes. The runner holes are arranged at both sides of the protruding part. The end of the protruding part is a sharp end. The utility model is provided with a protruding part at the outlet of the inner hot tip grating and the protruding part is provided with runner holes at both sides. While the utility model is used, the raw materials flow out of the runner holes on both sides and meet at the sharp end of the protruding part. The protruding part in the structure makes it very easy to break the rubber and avoids gluing, reducing the waste of raw materials and improving the smoothness of plastic injection operation.
Description
Technical field:
The utility model relates to the hot runner mould technical field, refers in particular to sharp-tongued structure within a kind of hot runner mould.
Background technology:
Hot runner mould is a kind of injection molding mould at present commonly used, and it is with respect to the mould of cold runner structure, has to economize in raw materials, and can enhance productivity, and improves product quality, simplifies plurality of advantages such as product subsequent handling.The hot mouth of hot runner mould generally includes hot mouth body, heating wire sleeve pipe, interior sharp-tongued and sharp-tongued outward, wherein between heating wire sleeve pipe and hot mouth body, be provided with heating wire, so that hot mouth body is heated, make the intrinsic raw material of hot mouth remain on molten condition.Interior sharp-tongued being positioned at below the hot mouth body, and the passage of interior sharp-tongued inside is communicated with sharp-tongued outside in outer sharp-tongued being sheathed on, a fixation with the runner of hot mouth body.Raw material is sharp-tongued in entering behind overheated mouth body, and by interior sharp-tongued flowing in the cast gate department, arrives at last in the moulding die cavity of mould.
In traditional hot runner mould, as shown in Figure 1, sharp-tongued inside is a passage 20 in it, and the upper port 21 of passage is coincide with the lower port of hot mouth body and docked, and interior sharp-tongued lower end outlet 22 is an independently hole, and the diameter in hole is less than the diameter of upper port 21.The existing deficiency of this structure is exactly: after injection moulding is finished, need disconnected glue (promptly cutting off the cast raw material that is connected between hot mouth and the mould), because the interior sharp-tongued lower end outlet 22 of this mould is a unobstructed through hole, when the shaping mould tool separates with hot mouth, raw material exports 22 easily and is taken out of from the lower end, do not allow easily broken glue, not only cause the waste of raw material, and influence the smooth and easy of processing yet.
The utility model content:
Technical problem to be solved in the utility model overcomes the shortcoming of present product exactly, provides a kind of and can effectively separate mouth structure within the hot runner mould of making a decision the glue problem, adopts the utility model can finish disconnected glue operation smoothly.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: sharp-tongued structure within the hot runner mould, should in sharp-tongued is a hollow channel, its exit is one-body molded to be had a protuberance, this protuberance to export between the sidewall with hot mouth to be formed with the runner hole.
Described runner hole is opened in the both sides of protuberance.
The end of described protuberance is a tip.
The utility model is provided with a protuberance in interior sharp-tongued exit, and these protuberance both sides are provided with the runner hole.During use, raw material is gone out then to meet at the tip of protuberance end by the runner orifice flow on both sides.After adopting this structure, because the existence of protuberance, the disconnected glue of order becomes very easy, the situation of glue can not occur connecting, reduces the waste of raw material, and has also improved the smoothness of injection molding operation.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the cutaway view of existing product;
Fig. 2 is a cutaway view of the present utility model;
Fig. 3 is a vertical view of the present utility model;
Fig. 4 is user mode figure of the present utility model.
The specific embodiment:
See Fig. 2,3, of the present utility model in sharp-tongued 10 inside be a hollow channel, it exports, and 11 places are one-body molded a protuberance 12, this protuberance 12 and hot mouth export and are formed with runner hole 13 between 111 sidewalls.
The end of described protuberance 12 is a tip 121.
See Fig. 4, the utility model in use, whole hot mouth 3 comprises hot mouth body 30, heating wire sleeve pipe 31, interior sharp-tongued 10 and outer sharp-tongued 32, wherein between heating wire sleeve pipe 31 and hot mouth body 30, be provided with heating wire 33, so that hot mouth body 30 is heated, make the raw material in the hot mouth body 30 remain on molten condition.In sharp-tongued 10 be positioned at hot mouth body 30 belows, and the passage of interior sharp-tongued 10 inside is communicated with the runner 31 of hot mouth body 30, outer sharp-tongued 32 be sheathed in sharp-tongued 10 outsides, work to fix interior sharp-tongued 10.Sharp-tongued 10 in raw material enters behind overheated mouth body 30, raw material goes out to meet at the tip 121 of the end of protuberance 12 through 13 backs, runner hole of interior sharp-tongued 10 outlets 11, flow in the cast gate department 34, arrives at last in the moulding die cavity of mould.
After adopting this structure, because the existence of protuberance, the disconnected glue of order becomes very easy, the situation of glue can not occur connecting, reduces the waste of raw material, and has also improved the smoothness of injection molding operation.
Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
