Abstract
The utility model discloses a kind of mould of plastics double-colored overmolding inverted mold structure, comprise two sprue bush, mould front mould part comprises panel, first and penetrates part and second penetrate part, first position penetrated is located at the upside of mould, panel back is provided with two groups of hot runner manifolds and provides the oil cylinder of power for ejection system, is provided with square iron after hot flow path, and Ejector Retainer Plate and thimble panel, be provided with mould A plate after square iron, slide block is located at above mould A plate; Mould rear mold part comprises mould B plate and die bottom plate.Rear mode structure is more simple, better can ensure that postrotational front and back mould rotates rear degree of agreement high, not easily occur melting glue phenomenon after product shaping.
Description
Technical field
The utility model relates to a kind of mould of plastics, especially relates to a kind of double-colored overmolding upside-down mounting mode structure be used on automobile plastic goods mould.
Background technology
In automobile plastic mould, along with product appearance requires more and more higher, usually there will be and have the injection moulding on same injection machine of two kinds of plastic materials, shaping at twice, but product depanning double-color mold situation once; Double-color mold is day by day prevailing, although this technique can make the outward appearance of product more beautiful, is easy to change color and can spray; But owing to involving great expense, technical requirement is high.And double color mould establishment has two characteristics: 1, because double coloured plastic injection machine is all rotate rear mold, so the front mould partial shape of double-color mold is different, but rear mold part is identical, front and back mould is with after central rotation 180 degree, must coincide, and first the product penetrated must stay rear mold, could be combined with the second product penetrated after rotation.2, when general two kinds of plastic materials are shaping, the first forming temperature penetrated is higher, and so second when penetrating shaping, and the first material penetrated can not melt again, just can be combined into qualified product.If first of double-colored product penetrates and stays rear mold, but forming temperature is penetrated low than second, so there will be after product shaping and melt glue phenomenon.
Utility model content
The utility model is not high enough for the existing double-colored overmolding inversion mode structure of solution also exists the rear goodness of fit of front and back mould rotation, there will be the present situations such as colloidal sol phenomenon after shaping and provide a kind of structure simple, after front and back mould rotates, degree of agreement is high, not easily occurs the mould of plastics double-colored overmolding inverted mold structure of melting glue phenomenon after product shaping.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of mould of plastics double-colored overmolding upside-down mounting mode structure, comprise two sprue bush, it is characterized in that: mould front mould part comprises panel, first and penetrates part and second penetrate part, first position penetrated is located at the upside of mould, panel back is provided with two groups of hot runner manifolds and provides the oil cylinder of power for ejection system, square iron is provided with after hot flow path, and Ejector Retainer Plate and thimble panel, be provided with mould A plate after square iron, slide block is located at above mould A plate; Mould rear mold part comprises mould B plate and die bottom plate.Rear mode structure is more simple, better can ensure that postrotational front and back mould rotates rear degree of agreement high, not easily occur melting glue phenomenon after product shaping.
As preferably, front mould part is provided with two groups of ejection systems, often organizes ejection system and comprises Ejector Retainer Plate, thimble panel and square iron part.
As preferably, after described hot runner manifold, be provided with three blocks of square iron.
As preferably, three blocks of described square iron divide and are located at hot runner manifold two ends below and middle position,
One group of Ejector Retainer Plate and thimble panel is provided with between adjacent square iron.The ejection system that better composition two groups is reliable and stable.
The beneficial effects of the utility model are: structure simplifies, and more can ensure to rotate the rear goodness of fit higher, and do two things equally after all, structure is simpler, more easily make the same.And carry out the power as ejection system with oil cylinder, replace the thrust of injection machine top rod.Emphasis is inverted die and double-color mold integrated application, and this type of product problem is readily solved.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the double-colored overlapping inverted die structural representation of the utility model.
Fig. 2 is right side of the present utility model TV structure schematic diagram.
Detailed description of the invention
In embodiment shown in Fig. 1, Fig. 2, a kind of mould of plastics double-colored overmolding inverted mold structure, comprise two sprue bush, mould front mould part comprises panel, first and penetrates part and second penetrate part, and the first position penetrated is located at the upside of mould, and panel back is provided with two groups of hot runner manifolds and provides the oil cylinder of power for ejection system, square iron is provided with after hot flow path, and Ejector Retainer Plate and thimble panel, be provided with mould A plate after square iron, slide block is located at above mould A plate; Mould rear mold part comprises mould B plate and die bottom plate.Front mould part is provided with two groups of ejection systems, often organizes ejection system and comprises Ejector Retainer Plate, thimble panel and square iron part.Three blocks of square iron are provided with after hot runner manifold.Three blocks of square iron divide and are located at hot runner manifold two ends below and middle position, are provided with one group of Ejector Retainer Plate and thimble panel between adjacent square iron.Front mould and rear mold are inverted, traditional ejection system is moved on to front mould, two characteristics that so double color mould is set up can meet, and the front mode structure of traditional moulds all can be simpler than rear mold, and after being so inverted, front mould becomes rear mold, and structure more simplifies.Front view and the right side view of what Fig. 1 and Fig. 2 represented respectively is double-colored overlapping inverted die.Just can see with traditional mould structure not quite alike from side view, below just probably introduce each several part.Double-shot moulding just has two sprue bush positions, and the first position penetrated is on the upside of mould, and first penetrates flange 2.Second position penetrated is the same with the position of traditional moulds, and second penetrates position 1, the second penetrates flange 3.The position of panel 4 is the same with traditional moulds with function.Panel 4 is below hot runner manifold 5, and the main body of two groups of hot flow paths all can be arranged on here, and provides actuator cylinder 9 to be also arranged on here for ejection system.Hot flow path 5 be below square iron 6, square iron one has 3 pieces, surrounds two groups of ejection systems, often organizes ejection system and comprises Ejector Retainer Plate 7 and thimble panel 8 and square iron.Be mould A plate 10 after square iron, slide block 11 is arranged on above mould A plate 10.These are exactly front mould part above, and the most of structure in this mould is all on front mould.Rear mold part is relatively fairly simple, just only remaining mould B plate 12 and die bottom plate 13.
Although more employ the terms such as mould B plate, mould A plate, slide block, oil cylinder herein; But do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
