Description
Technical field
The present invention relates to a kind of double color mould.
Background technology
At present, the double color mould of prior art or needs two secondary moulds, or need two patrixes; die is needed to rotate; these double color moulds all have a common ground to be exactly after all needing patrix or dynamic model to open, and matched moulds just can carry out the injection moulding of another colorant again, then mold integral is larger; ejecting mechanism is also more complicated; the maintenance period of mould is shorter, and maintenance cost is also just higher, and the simultaneously whole production cycle is also longer; production efficiency is lower, causes production cost higher.
Summary of the invention
The present invention is directed to above problem and the double color mould that a kind of volume is relatively little, structure simple, maintenance cost is lower and production efficiency is higher is provided.
The present invention overcomes the above problems technical scheme used: provide a kind of double color mould with following structure, it comprises fixed half and moving half, die cavity is formed after described fixed half and moving half matched moulds, described die cavity is divided into flexible glue die cavity and ebonite die cavity, described cover half is provided with flexible glue cast gate and ebonite cast gate, and flexible glue cast gate is communicated with ebonite die cavity with flexible glue die cavity respectively with ebonite cast gate, described dynamic model slidably connects blade flexible glue die cavity and ebonite die cavity separated, described blade one end is positioned at flexible glue die cavity, and the lower plane of blade is concordant with the transition position of ebonite die cavity with flexible glue die cavity, the end face of blade one end is identical with just right soft jelly mould cavity wall shape, the other end of blade is positioned at cover half, the driving mechanism controlling blade slides is provided with in described cover half.
After adopting above structure, compared with prior art, the present invention is owing to separating flexible glue die cavity and ebonite die cavity blade, then when injection moulding, flexible glue die cavity and ebonite die cavity first separate by blade, now first injection moulding ebonite, after ebonite injection moulding terminates, driving mechanism drives blade slides, flexible glue die cavity is communicated with ebonite, at this moment injection moulding flexible glue can realize double-shot moulding again, do not need die sinking in the process, do not need to rotate die, also two secondary moulds, significantly can reduce the overall volume of mould, also difficulty of processing and the complexity of ejecting mechanism can be reduced, thus extend the maintenance period of mould, reduce maintenance cost, and the whole production process cycle is shorter, production efficiency is higher, because die sinking event yield rate is not higher yet, significantly can reduce production cost.Therefore the feature that the present invention has that volume is relatively little, structure simple, maintenance cost is lower and production efficiency is higher.
As improvement, described driving mechanism is oil cylinder or cylinder, and oil cylinder or cylinder are positioned at cover half, and described oil cylinder or the piston rod of cylinder are connected with the other end of blade; Then technology maturation, structure is simple, and action response is very fast, and reliability is better, can reduce preparation cost of the present invention.
As further improvement, the axis of described oil cylinder or the piston rod of cylinder is vertical with the glide direction of blade, and piston rod is provided with slide block, slide opening is provided with in described cover half, and skid is connected in slide opening, described slide block is provided with the block of tiltedly loosing core that cross section is " T " font, and the other end of described blade is located at the groove be slidably matched with block of tiltedly loosing core; After then arranging like this, counter when injection moulding of blade can be eliminated and move back situation, to eliminate corresponding injection defect, improve yield rate; Also make whole driving mechanism all be positioned at cover half simultaneously, the impact of outer bound pair driving mechanism can be eliminated, make stability in use of the present invention better.
As improving further again, in the cover half of described slide opening upper end, be provided with the first limited block to cap slider position; After then the first limited block is arranged, make the accuracy of blade moving better, not easily occur that blade is by situation bad for soft jelly mould cavity wall top, improves stability in use further, and extends the maintenance period of mould, reduce maintenance cost.
As further improving, the sidewall of described slide opening is provided with the spacing hole spacing to ram travel, and described slide block is provided with and coordinates the second spacing limited block with spacing hole; Described spacing hole is positioned on the slide opening sidewall away from blade, and spacing hole is through hole; Then the second limited block not only adds a upper limit, also increase a lower limit, when slide block is moved up, the stability of location is better, even if one of them limited block lost efficacy, also have another can ensure that blade normally works, therefore stability in use of the present invention is better; Location when lower limit makes again blade retract simultaneously is more accurate, thus effectively prevents the situation occurring injection defect at blade place, and yield rate during injection moulding of the present invention is improved further; And spacing hole is through hole, is convenient to the processing of spacing hole and the installation of the second limited block, thus reduces preparation cost of the present invention.
