Description

A kind of bicolor injection mould
Technical field
The utility model relates to a kind of bicolor injection mould.
Background technology
Double-shot moulding refers to two kinds of different colours, different types of plastics, mostly is a kind of flexible plastic and the collocation of a kind of duroplasts, carries out injection moulding in a certain order, effectively combined by two kinds of plastic cement, become a complete product by double coloured plastic injection machine.Bicolor injection mould is for above-mentioned injection moulding process, usually, because the process of double-shot moulding is comparatively complicated, the runner of mould is complicated, the selection of feed entrance point is more difficult, common bicolor injection mould generally all only has a product, two die cavities, due to twice injection moulding of each needs of common double-colored injecting products, so identical when its flexible glue material will be produced, during the also identical multiple product of ebonite material, just need to make many molds, and Multi-step injection molding, in addition in injection moulding production process, the demoulding of plastic product has been come by the push rod on mould, namely after completing injection step, dynamic model and cover half are separately, the ejection cylinder that the push rod be arranged on dynamic mould core is injection molding machine ejects, product is ejected from core.Or a stripper plate is set, stripper plate ejects by push rod, is ejected by the root of product from its bead and core by stripper plate, but when the wall of product is thinner, push rod is easily by product bursting, and when particularly the toughness of material is poor, this situation more easily occurs; When shape of product is complicated, be then not suitable for using stripper plate structure.
Utility model content
In view of this, it is simple that the purpose of this utility model is to provide a kind of structure, and material circulates smooth and easy in runner, the uniform force during demoulding, not a kind of bicolor injection mould of cracky.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of bicolor injection mould, comprise dynamic model, cover half and shaping mold cavity, this shaping mold cavity comprises single injection-molded die cavity and secondary injection molding die cavity, described single injection-molded die cavity and described secondary injection molding die cavity are respectively to having the main note seat nozzle and secondary injection seat nozzle that are communicated with it, it is characterized in that: described dynamic model comprises a mould sole, and be movably connected on the rotor plate of this mould sole upper surface, described rotor plate outer end edges edge and the briquetting movable contact be fixedly connected on described mould sole; Described mould sole centre place is provided with an air inlet pipe, and described air inlet pipe is communicated with an air cavity, and described air cavity upper end is connected with gas flow tube, and described gas flow tube is corresponding with described shaping mold cavity; The inner tubal wall of the runner that described main note seat nozzle is communicated with described shaping mold cavity respectively with described secondary injection seat nozzle is provided with Electric radiant Heating Film.
Preferably, above-mentioned a kind of bicolor injection mould, wherein said rotor plate adopts positioning ball to be connected with described mould sole.
Preferably, above-mentioned a kind of bicolor injection mould, wherein said gas flow tube is provided with multiple, is also connected with mozzle between its lower end and described air cavity.
Preferably, above-mentioned a kind of bicolor injection mould, wherein said single injection-molded die cavity and described secondary injection molding die cavity corresponding be connected to two gas flow tube.
Compared with prior art, the utility model technique effect is mainly reflected in: in the utility model, dynamic model part rotates, during first time injection moulding, the first plastics injects and is full of single injection-molded die cavity by main note seat nozzle, pull handle with hand after Qi Mo and do 180 degree of rotations by positioning ball location, at the first plastic without under the state of the demoulding, inserts carries out second time mold closing again, the secondary injection seat nozzle perpendicular with injection machine is injected, and the second plastics are filled secondary injection molding die cavity.Meanwhile, main note seat nozzle still can carry out injection moulding to single injection-molded die cavity.After second time opens mould, just can carry out air-flow to eject, take out goods, the inner tubal wall of runner that main note seat nozzle is communicated with shaping mold cavity respectively with secondary injection seat nozzle is simultaneously provided with Electric radiant Heating Film, plastics inject flowing limit, flow process limit at runner and keep heating, circulate smooth and easy.
Accompanying drawing explanation
Fig. 1: the utility model structural representation.
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, is easier to make technical solutions of the utility model understand and grasp.
As shown in Figure 1, a kind of bicolor injection mould, comprise dynamic model, cover half and shaping mold cavity, this shaping mold cavity comprises single injection-molded die cavity 1 and secondary injection molding die cavity 2, described single injection-molded die cavity 1 and described secondary injection molding die cavity 2 are respectively to having the main note seat nozzle 3 and secondary injection seat nozzle 4 that are communicated with it, wherein said dynamic model comprises a mould sole 5, and be movably connected on the rotor plate 6 of this mould sole 5 upper surface, described rotor plate 6 outer end edges edge and briquetting 7 movable contact be fixedly connected on described mould sole 5, briquetting 7 is fixedly connected on mould sole 5 by set bolt 8, described mould sole 5 centre place is provided with an air inlet pipe 9, and air inlet pipe 9 outer end is socketed with a positioning sleeve 10, and described air inlet pipe 9 is communicated with an air cavity 11, described gas, and 11 upper ends are connected with gas flow tube 13, and described gas flow tube 13 is corresponding with described shaping mold cavity, the inner tubal wall of the runner that described main note seat nozzle 3 is communicated with described shaping mold cavity respectively with described secondary injection seat nozzle 4 is provided with Electric radiant Heating Film.
Wherein, described rotation 6 adopts positioning ball 14 to be connected with described mould sole 5; Described gas flow tube is provided with multiple, is also connected with mozzle 12 between its lower end and described air cavity; Described single injection-molded die cavity 1 and described secondary injection molding die cavity 2 correspondence be connected to two gas flow tube 13.
