Description

The sound basin ejection shaping die of loud speaker

The utility model relates to a kind of mould, refer to especially a kind of can be by twice ejaculating forming processing and sound basin and its basin edge forming of loud speaker integrally combined, and then can improve the production capacity of sound basin, the sound basin ejection shaping die of the loud speaker of reduction manufacturing cost and fraction defective.

As shown in Figure 1, the sound basin 60 of basin type loud speaker is equipped with an outstanding limit 70 at its basin edge; Wherein, sound basin 60 was normally being made by the paper material moulding in the past, and outstanding limit 70 is normally made by the preferable material of a kind of amplitude (as rubber or similar material) moulding.Because sound basin 60 is different materials with outstanding limit 70, therefore after moulding is made separately, must be combined via binding fabrication schedule again.Through looking into, the sound basin 60 of existing in recent years part changes being made by plastic cement material, though and can make with short time moulding by Jet forming machine with the sound basin 60 that plastic cement material is made, and then can reach the purpose that improves production capacity and reduce cost.But this with the made sound basin 60 of plastic cement material also since its material with different in order to make the material of hanging limit 70, therefore sound basin 60 and outstanding limit 70 be after moulding is made separately, still must be again just can reach the purpose that combines by mold and artificial location, gluing, pressing mold with dried bonding fabrication schedule such as admittedly; Therefore, the sound basin 60 made with plastic cement material still exists shortcoming very time-consuming, that take a lot of work with combining of its outstanding limit 70, in addition, because fabrication schedule is too complicated, also will cause the high shortcoming of fraction defective.

The purpose of this utility model is that the existing above-mentioned shortcoming of ejection shaping die is commonly used in employing at loudspeaker cone, so that a kind of sound basin ejection shaping die of the loud speaker that adopts twice ejaculating forming processing and sound basin and its basin edge forming of loud speaker combined to be provided, and then help to improve sound basin production capacity, reduce manufacturing cost and fraction defective.

For achieving the above object, the utility model is taked following technical scheme:

A kind of sound basin ejection shaping die of loud speaker, it comprises at least one male model and one first master mold, second master mold; Wherein: the die face of male model is provided with and becomes cone shape convex body without exception, and is provided with a sound basin forming tank in this convex body, and is equipped with a blocking convex lip in the outer rim of sound basin forming tank, and is equipped with an outstanding edge forming groove in the outer rim of blocking convex lip; The die face of first master mold is provided with and becomes cone shape groove without exception, this coniform groove is to be symmetrical in the set convex body of male model die face, and the groove edge of groove is to be to be absorbed in shape and to have a potential difference with die face, and again, the diameter of groove just can contain the blocking convex lip outer rim that covers in male model; The die face of second master mold is provided with and becomes cone shape groove without exception, this coniform groove is symmetrical in the set convex body of male model die face, and establish an outstanding edge forming groove in the groove edge ring of groove, the inner edge of this outstanding edge forming groove extends internally a suitable distance and is overlapped in the outer rim of sound basin forming tank.

Design by above-mentioned male model and first master mold, second master mold, and cooperation twice ejaculating forming, and when the male model and the first master mold matched moulds, utilized set blocking convex lip on male model, and set groove groove edge just can contain the blocking convex lip outer rim that covers in male model on first master mold, and be able between the male model and first master mold to form a complete sound basin forming tank, and then can be at the first time of ejection formation sound basin smoothly during ejection formation; And when the male model and the second master mold matched moulds, can between in type sound basin outer rim and the male model and second master mold, form a complete outstanding edge forming groove, and then can be when ejaculation second time type the outstanding limit of ejection formation smoothly, simultaneously by the inner edge of outstanding edge forming groove extend internally one suitably distance be overlapped in the outer rim of sound basin, and outstanding limit is combined in ejection formation with the sound basin.
