Abstract
The utility model discloses an injection mold, which comprises a female cavity, wherein a sub-runner is arranged in the female cavity; a stripper plate is arranged upon the female cavity; a sprue bushing is arranged in the stripper plate; a main runner is arranged in the sprue bushing, and is communicated with the sub-runner; the sprue bushing is fixed on the stripper plate; and the length of the sprue bushing is less than the thickness of the stripper plate. Since the main runner of the sprue bushing of the injection mold is shortened, the injection pressure of melted fluid material is ensured, the injection effect is improved, and the material is saved.
Description
Technical field
The utility model relates to a kind of injection mold, relates in particular to a kind of improvement structure of injection mold being irritated mouth.
Background technology
To be the fluent material that is used to make fusion be injected into the parts of the runner of mould inside from the nozzle of injection machine to filling mouth in the mould, and it is connected with sprue by the filling mouth mouth that links to each other with the nozzle of injection machine and forms, and the sprue other end communicates with the runner of mould.
Filling mouth 110 in the mould normally directly is fixed on the fixed head 102 at present, the body extension of this filling mouth 110 is set in the stripper plate, to form sprue 111, as shown in Figure 1, but such fixed form makes that filling mouth sprue 111 is oversize, the injection pressure of fluid can reduce gradually because of runner is oversize, influence the injection moulding effect, and the oversize mobile frictional resistance of the plastic liquid of fusion that also can make of runner strengthens, rate of flow of fluid is slowed down, cause the fluent material of fusion to solidify in advance, not only influence the injection mold molding effect, also can waste raw material simultaneously.
Therefore, injection mold of the prior art is irritated mouth structure and is still waiting improvement.
The utility model content
The purpose of this utility model is to provide a kind of and can guarantees injection pressure and save raw-material mould filling mouth structure, realizes by sprue in the shortening injection mold filling mouth.
Technical solutions of the utility model are:
A kind of injection mold is provided, has comprised mother module core, be provided with runner in this mother module core, the top of this mother module core is provided with stripper plate, wherein, is provided with Yi Guanzui in described stripper plate, is provided with a sprue in the described filling mouth, and described sprue communicates with described runner; Described filling mouth is fixed on the described stripper plate, and the length of described filling mouth is less than the thickness of described stripper plate.
Injection mold described in the utility model, wherein, described stripper plate comprises first stripper plate, is provided with second stripper plate between described first stripper plate and the described mother module core, described filling mouth is fixed on described second stripper plate, and the length of described filling mouth sprue equates with the described second stripper plate thickness.
Injection mold described in the utility model, wherein, opening is bowl-type above the described filling mouth on the described stripper plate.
Injection mold described in the utility model, wherein, on described first stripper plate, the opening of corresponding described filling mouth top is bowl-type.
Injection mold in the utility model is by shorten irritating the sprue of mouth, and will irritate mouth and be fixed on the stripper plate, guaranteed the injection pressure of melt flow stream material, improved the injection moulding effect, and reached the raw-material purpose of saving.
Description of drawings
Fig. 1 is that injection mold of the prior art is irritated the mouth structure schematic diagram;
Fig. 2 is that the injection mold of the utility model embodiment is irritated the mouth structure schematic diagram;
Fig. 3 irritates the mouth structure schematic diagram for the injection mold that comprises second stripper plate of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, will be described in detail preferred embodiment of the present utility model.
Injection mold described in the utility model is three template dies, as shown in Figure 2, comprises mother module core 205, stripper plate 202.Wherein be provided with runner 204 in the mother module core 205, the top of this mother module core 205 is provided with stripper plate 202, in stripper plate 202, be provided with Yi Guanzui, one sprue 211 is set in this filling mouth, this sprue 211 communicates with runner 204, in structure of the present utility model was provided with, outspoken the connecing of this filling was fixed on the described stripper plate 202.Irritate the length of mouth and the thickness of described stripper plate and adapt, promptly irritate the thickness of the length of mouth less than stripper plate.Be fixed on the length that then can obviously shorten filling mouth and sprue thereof on the stripper plate with irritating mouth.Opening is bowl-type above the described filling mouth on the described stripper plate, is convenient to the fusion injected plastics material and pours into.
Stripper plate in the utility model can be set to two, i.e. first stripper plate 206 and second stripper plate 203, as shown in Figure 3, wherein second stripper plate 203 is arranged between first stripper plate 206 and the mother module core, irritating mouth 210 is fixed on first stripper plate 206, the sprue 211 of irritating mouth originates in second stripper plate 206, extends to runner 204 inlets in the mother module core, and its length equates with the thickness of described second stripper plate 203.Injection mold described in the utility model, on described first stripper plate, the opening of corresponding described filling mouth top is bowl-type, is convenient to the fusion injected plastics material and pours into.
During injection mold, the material to be formed of fusion flows into its sprue 211 by the opening 210 of irritating mouth, because its opening is big, sprue is short, increased its injection pressure, fluid is flowed through and is entered described runner 204 behind the sprue, and runner 204 is communicated with mould gate, fluid is injected the product die cavity, finish injection moulding.Because the sprue in the utility model scheme is short, injection pressure is big, has reduced raw-material waste greatly, has improved productivity simultaneously.
When filling mouth structure of the present utility model was applied to two template dies, because two template dies do not have stripper plate, outspoken the connecing of then described filling was fixed on the mother module core, can shorten its sprue greatly, reaches the technique effect same with the utility model.
In sum, the injection mold in the utility model is by shorten irritating the sprue of mouth, and will irritate mouth and be fixed on the stripper plate, guaranteed the injection pressure of melt flow stream material, improved the injection moulding effect, and reached the raw-material purpose of saving.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
