Description
Technical field
The present invention relates to a kind of double-color mold, specifically a kind of double-color mold for fascia.
Background technology
Double-color mold refers to the plastic having obvious boundary between two kinds of colored plastics.Use the injector of two or more injecting systems, the plastics of different cultivars or different color and luster are injected into simultaneously or successively the manufacturing process in mould, be called two-color injection-molded, its mould used is referred to as two-color injection-molded mould.Double color mould has two secondary moulds usually, and half is contained on the cover half fixed head of double color mould injection machine, and second half is contained on dynamic model finger plate.After the first Material injection, die sinking, one time dynamic model rotates 180 ° with primary production product, and now dynamic model does not eject, then matched moulds, carries out the injection moulding of the second material, and die sinking after cooling, dynamic model side product is ejected.
Fascia is working of plastics, total is ebonite injection moulding, in order to ensure the existing intensity of decorative panel for automobile, cushioning effect can be played again, need injection moulding flexible glue on decorative panel for automobile ebonite, according to prior art, common double-color mold is adopted to carry out injection moulding, because the groove for injecting flexible glue has a lot, a large amount of runners is needed to complete injection moulding, and one take turns injection moulding after can produce a large amount of waste materials, cost is large, simultaneously ebonite injection moulding side and flexible glue injection moulding side as a whole, heat transmission is had between ebonite injection moulding and flexible glue injection moulding in injection moulding process, such meeting is disturbed mutually, the temperature of the colloid in runner is unstable, have a strong impact on the quality of injection moulding.
Summary of the invention
Technical problem to be solved by this invention is: the defect overcoming above prior art, provide a kind of can not produce waste material cost low and in runner colloid temperature ensure the double-color mold for fascia of injection moulding quality.
The technical solution used in the present invention is: a kind of double-color mold for fascia, comprise solid plate, dynamic model rotary disk, product, first mould and the second mould, described solid plate is provided with flexible glue injection hole and ebonite injection hole, described flexible glue injection hole is positioned on the first mould, described ebonite injection hole is positioned on the second mould, first described mould one end is fixed on solid plate, the first described mould other end is fixed on dynamic model rotary disk, second described mould one end is fixed on solid plate, the second described mould other end is fixed on dynamic model rotary disk, the first described mould and the second mould include cover half fixed head, cover half, dynamic model and dynamic mould fixing plate, described dynamic mould fixing plate is fixed on dynamic model rotary disk, described dynamic model is fixed on dynamic mould fixing plate, described cover half fixed head is fixed on bottom solid plate, described cover half is fixed on bottom cover half fixed head, described product is provided with several flexible glue blocks, slide block is provided with in the first described mould and the second mould, described cover half, dynamic model and slide block form the die cavity being used for shaped article, spacing is had between the first described mould and the second mould, the ejecting mechanism for product being stayed on dynamic model is provided with between described cover half fixed head and cover half, the dynamic model of the first described mould is provided with at least one first Flexible glue runner be communicated with flexible glue injection hole, described cover half is provided with the die cavity for shaping flexible glue block, described die cavity and flexible glue block one_to_one corresponding, the first described Flexible glue runner is at least communicated with a die cavity.
After adopting above structure, the present invention compared with prior art has the following advantages: fascia is exactly bag flexible glue on ebonite, existing mould flexible glue injection hole side directly contacts with ebonite injection hole side, the heat on both sides is mutually conducted and is influenced each other, have impact on colloid temperature, greatly have impact on injection moulding effect, runner directly extends in the die cavity of cover half, because flexible glue number of blocks is many, the runner needed is many, simultaneously because runner is positioned at the top of die cavity, because there is cooling pipe top, fluid can condense, form waste material, produce waste, cost is large, the present invention utilizes between the first mould and the second mould has spacing to affect to the heat trnasfer eliminated between them, make the fluid temperature (F.T.) in runner more stable, ensure that injection moulding quality, flexible glue flows to die cavity from the first Flexible glue runner simultaneously, be equivalent to flow to cover half from dynamic model, flexible glue is in fluid state always, waste can not be caused, cost greatly reduces.
As preferably, at least two connections between described die cavity, the runner demand of injection moulding die cavity is few, and cost is few.
As preferably, between described die cavity, at least two connections refer in cover half the second Flexible glue runner being provided with and being communicated with die cavity, and structure is simple, easily realizes.
