Abstract
The utility model discloses a mold and a molded product. The mold is used for molding engineering plastics. The mold comprises an injection molding runner, a male die and a female die, wherein the male die and the female die form at least two cavities, and a branch injection molding runner is connected with each cavity; each cavity is connected with the injection molding runner through the branch injection molding runner; and the at least two cavities are same in corresponding shapes, but different in specifications. The mold disclosed by the utility model can be used for molding more than two LED (light-emitting diode) plastic lampshades with different thicknesses at the same time, and can be used for testing the effect of the thicknesses of the lampshades on the optical performance of an LED lamp bead.

Background technology
Multiple mould for injection mo(u)lding is arranged at present on the market, generally comprise male model and master mold, the die cavity that male model and master mold form, general mould all is used for the one-shot forming production technology of batch production, but under some environment, need the disposable difform injection moulding making of using, in the test to the light performance impact under LED lampshade thickness, just need to use the LED lampshade of different-thickness, but rarely have mould to be used for once producing the mould of different products at present.
The utility model content
In sum, in order to address the above problem, the utility model is necessary to provide a kind of mould, can be used for the mechanograph that one-shot forming is identical shaped and specification is different.
Further, the utility model also provides a kind of mechanograph.
The technical scheme that the utility model adopts is:
A kind of mould, be used for the moulding engineering plastics, comprise injection moulding running channel, male model and master mold, described male model and master mold form at least two die cavities and the injection moulding runner that links to each other respectively with described each die cavity, each die cavity links to each other with described injection moulding running channel by the injection moulding runner, has two at least the corresponding shape of die cavity is identical but specification different.
The shape that the die cavity of the utility model indication is corresponding refers to a kind of solid geometry shape spatially.
Wherein, described die cavity is the die cavity for moulding LED lampshade.
Wherein, the shape that described die cavity is corresponding is Loadings On Hemispherical Shell or semielliptical housing.
Wherein, described Loadings On Hemispherical Shell or Semi Ellipsoidal Shells body thickness are even.
Wherein, described injection moulding runner is provided with shutoff valve.
Wherein, described die cavity is four, and shape corresponding to described four die cavities all is Loadings On Hemispherical Shells of even thickness, and the thickness of described four Loadings On Hemispherical Shells is respectively 0.8-1.2mm, 1.3-1.7mm, 1.8-2.2mm, 2.3-2.7mm.
Wherein, the thickness of described four Loadings On Hemispherical Shells is respectively 1mm, 1.5mm, 2mm, 2.5mm.
Wherein, the described four groups of corresponding injection moulding runner of die cavity equal in length.
A kind of mechanograph, the mechanograph that forms by above-described die casting.
Wherein, described mechanograph is that four shapes are identical, the LED lampshade that thickness does not wait.
Compare prior art, mould described in the utility model, can two or more difform mechanograph of one-shot forming, can be used for the simultaneously different LED plastic lamp shade of two above thickness of moulding especially, can be used for lampshade thickness to the test of LED lamp bead optical performance impact.
