Abstract
The utility model provides a double-color injection mould. The double-color injection mould comprises an injection molding front mould, an injection molding rear mould, and a rotary plate between the injection molding front mould and the injection molding rear mould, wherein the injection molding front mould comprises a pair of male mould and female mould which are oppositely arranged; the male mould and the female mould of the front mould are combined to form a first mould cavity with the shape corresponding to that of a to-be-prepared product; the injection molding rear mould comprises a pair of male mould and a female mould which are oppositely arranged; the male mould and the female mould of the rear mould are combined to form a second mould cavity with the shape corresponding to that of the to-be-prepared product; at least one rubber film movable mould is arranged at each of the lower ends of the first mould cavity and the second mould cavity. According to the technical scheme, slide block assemblies in the injection mould are effectively reduced, so that the mould structure is simple.
Description
Technical field
The utility model relates to injection mold, more particularly, relates to a kind of bicolor injection mould.
background technology
Double-shot moulding refers to two kinds of different colours, and different types of plastics mostly are a kind of flexible plastic and the collocation of a kind of duroplasts, carry out in sequence injection moulding by double coloured plastic injection machine, and two kinds of plastic cement are combined, and become a complete product.Bicolor injection mould is for above-mentioned injection moulding process.Conventionally because the process more complicated of double-shot moulding, require the precision of mould high, mould top shoe is more, hot flow path complexity, the selection of feed entrance point is more difficult, common bicolor injection mould is all generally to only have a product, two die cavities, due to twice injection moulding of the each needs of common double-colored injecting products, so identical when producing its flexible glue material, ebonite material is also when identical multiple product, just need to make many molds, and Multi-step injection molding, not only time-consumingly also waste raw material, because product is independent individuality, be unfavorable for the automation processing of subsequent handling, and the conventional machinery control slide block action of mould, precision is not high yet, location precision to mould is larger.
In addition, injection mold comprises the cooling duct of cooling fluid process.Injection molding also comprises the assembly being configured to separating with described mould at the inner injection molded article of manufacturing of die cavity, in other words, is configured to assembly that injection molded article is released from described mould, for example, and knockout pin, head board and cushion block.Therefore, in injection mold, slide block assembly is a lot, so that mould structure seems more complicated.
Summary of the invention
In view of this, it is few that the purpose of this utility model is to provide a kind of slide block assembly, the mould structure simple bicolor injection mould that seems.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bicolor injection mould, comprise injection moulding front mould and injection moulding rear mold, and be arranged on the swivel plate between injection moulding front mould and injection moulding rear mold, described injection moulding front mould comprises front mould male model and the front mould master mold of pair of opposing, front mould male model and front mould master mold are in conjunction with forming shape and the first die cavity for the treatment of that article shape is corresponding, described injection moulding rear mold comprises rear mold male model and the rear mold master mold of pair of opposing, rear mold male model and rear mold master mold are in conjunction with forming shape and the second die cavity for the treatment of that article shape is corresponding, the lower end of wherein said the first die cavity and the second die cavity is respectively respectively arranged with at least one glued membrane dynamic model.
Preferably, above-mentioned bicolor injection mould, the lower end of wherein said the first die cavity is provided with a glued membrane dynamic model, and the lower end of described the second die cavity is provided with three glued membrane dynamic models.
More preferably, above-mentioned bicolor injection mould, glued membrane dynamic model and the front mould master mold of wherein said the first die cavity lower end are fixed, and glued membrane dynamic model and the rear mold master mold of described the second die cavity lower end are fixed.
In addition, above-mentioned bicolor injection mould, three glued membrane dynamic models of wherein said the second die cavity lower end are evenly spaced apart successively.
The utility model technique effect is mainly reflected in: the lower end of the first die cavity and the second die cavity is respectively respectively arranged with at least one glued membrane dynamic model, use glued membrane dynamic model to replace traditional knockout pin, head board and cushion block or other separation assemblies, slide block assembly in a whole set of injection mold structure is greatly reduced, make injection mold structure seem simple.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand and grasp.
As shown in Figure 1, a kind of bicolor injection mould, comprises injection moulding front mould 1 and injection moulding rear mold 2, and is arranged on the swivel plate 3 between injection moulding front mould 1 and injection moulding rear mold 2.
Injection moulding front mould 1 comprises front mould male model 10 and the front mould master mold 11 of pair of opposing, and front mould male model 10 and front mould master mold 11 are in conjunction with forming shape and the first die cavity 4 for the treatment of that article shape is corresponding; Injection moulding rear mold 2 comprises rear mold male model 20 and the rear mold master mold 21 of pair of opposing, and rear mold male model 20 and rear mold master mold 21 are in conjunction with forming shape and the second die cavity 5 for the treatment of that article shape is corresponding.
The lower end of the first die cavity 4 is provided with a glued membrane dynamic model 6, and this glued membrane dynamic model 6 is fixed together with front mould master mold 11.
The lower end of the second die cavity 5 is provided with three glued membrane dynamic models 6, and these three glued membrane dynamic models 6 are evenly spaced apart and be fixed together with rear mold master mold 21 successively.
Below be only concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on rights protection scope of the present invention.
