Abstract
The utility model relates to a three-way rotatable throttling valve with an insert. The throttling valve (1) is cylindrical; a sprue puller (2) is arranged in the center of the throttling valve (1); four screw holes (3) are formed in the edge of the throttling valve (1) and center around the sprue puller (2); four runners distributed in a crossed manner and centering around the sprue puller (2) are arranged on the throttling valve (1); three of the four runners distributed in a crossed manner are communicated runners (7); the other runner is a cut-off runner (6); the communicated runners (7) are respectively connected with a runner on a mould; the runner port of the cut-off runner (6) is closed; and the communicated runners (7) are matched with the runner on the mould. The three-way rotatable throttling valve with the insert is simple to operate when throttling or non-throttling adjustment is required, is free of frequent replacement and has the advantages of rejection rate and plastic material loss reduction, low probability of damage and low manufacturing cost.
Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a kind of mold insert three way type rotatable type choke valve.
Background technology
Usually can be according to actual needs in actual die trial or in producing indivedual cast gates or runner be taked the way that temporarily stops, in the existing structure, the mode that adopts sizing material to go to block up is usually advanced glue, can't realize injecting as required, and have following problem:
1. consuming time more when actual die trial or production, the plastic material loss is big, and percent defective is higher;
2. existing employing mode complex operation, it is higher to change frequency;
3. comparatively practical under the narrow and small state of die space.
Summary of the invention
The utility model technical problem to be solved provides a kind of mold insert three way type rotatable type choke valve, and the plastic material loss is big, percent defective is higher, the problem of complex operation to solve.
The utility model solves the technical scheme that its technical problem adopted: a kind of mold insert three way type rotatable type choke valve is provided, and described choke valve is cylindrical, and described choke valve center is provided with sprue puller; Be that the center is arranged with four screw holes with the sprue puller on the described choke valve edge; It is four sections runners that the center is crossing distribution that described choke valve is provided with the sprue puller; Three sections runners are arranged for being communicated with runner in four sections runners of described crossing distribution, another section runner is for cutting off runner; Described connection runner respectively with mould on runner communicate; The runner port of described partition runner is closed.
Described connection runner and mold runner match.
Beneficial effect
The utility model relates to a kind of mold insert three way type rotatable type choke valve, compared with prior art has following advantage:
1. simple to operate when needing throttling or non-throttling adjustment, need not frequent transposing;
2. the rate of reducing the number of rejects and seconds reduces the plastic material loss, practices thrift cost;
3. not fragile, low preparation cost.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
To shown in Figure 4, the utility model is a kind of mold insert three way type rotatable type choke valve like Fig. 1, and described choke valve 1 is cylindrical, and described choke valve 1 center is provided with sprue puller 2; Be that the center is arranged with four screw holes 3 with sprue puller 2 on described choke valve 1 edge; It is four sections runners that the center is crossing distribution that described choke valve 1 is provided with sprue puller 2; Three sections runners are arranged for being communicated with runner 7 in four sections runners of described crossing distribution, another section runner is for cutting off runner 6; Described connection runner 7 respectively with mould on runner communicate; The runner port of described partition runner 6 is closed.
Be fixed in the runner zone of mold cores 5 through screw hole 3 choke valves 1 with soket head cap screw.During use, soket head cap screw being unclamped, is that pivot is adjusted with choke valve 1 with middle sprue puller 2.As shown in Figure 5, when being adjusted into two when logical, it is vertical with the runner of mold cores 5 to cut off runner 6, and the right and left circulates all can advance glue; As shown in Figure 6, when advancing glue on the right of being adjusted into, it is parallel with the runner of mold cores 5 to cut off runner 6, and is positioned on the runner of the left side, and the right runner is communicated with, and left side runner cuts off; As shown in Figure 7, when being adjusted into the left side and advancing glue, it is parallel with the runner of mold cores 5 to cut off runner 6, and is positioned on the runner of the right, and left side runner is communicated with, the right runner partition.
Claims (2)
