Abstract
The invention discloses an injection mold used for molding a two-layer and two-color product. The injection mould comprises a mold blank that is provided with a movable mold plate and a fixed mold plate, which is corresponding to a two-color injection device. The movable mold plate is provided with two movable molds, the fixed mold plate is provided with a fixed mold. The two movable molds are abreast arranged in the plane of the movable mold plate, which is arranged on a linear type sliding rail consistent with the arrangement direction of the two movable molds. The movable mold plate is connected with a driving device and driven by the driving device to reciprocate along the sliding rail; the size of a molding chamber formed by one of the two movable molds matching the fixed mold is more than that of a molding chamber formed by another movable mold matching the fixed mold; the control device of the driving device is connected with the two-color injection device through a signal line. The difference of the injection molding method from the general two color injection molding method is that the two movable molds on the same of mould sequentially match with the fixed mold through the linear movement of the movable mold plate to realize the two-color and two-layer injection molding.

According to above technical scheme, the invention provides the injection mold that is used for the forming double-layer double-color goods, different with existing mould, it is corresponding with a cover half that it has two dynamic models, perhaps two cover half and corresponding being installed on the same mold base of dynamic model, when mold base is installed on the injection machine that is provided with the double color injection device, wherein template can be up and down or left and right sides straight line move, therefore utilize above-mentioned mould and injection moulding process, a mold can be only used, just high efficiency can be realized, large-area double-layer bi-color, moulding when being the second layer and base layer unlike material and/or color.Owing to only need to adopt a mold, nor need special double coloured plastic injection machine, just can inject the product of Double colour double-deck, thereby can alleviate plasthetics manufacturer's cost of investment, and the manufacturing cost of product.
Description of drawings
The injection moulding process that the present invention is used for the injection mold of forming double-layer double-color goods and uses this mould below in conjunction with the drawings and the specific embodiments is described further.
Accompanying drawing 1 is the stereogram of mould among the present invention.
The specific embodiment
Mould of the present invention is mainly used in household appliances, auto parts machinery, the production of plasthetics such as mechanical fitting and articles for daily use.As shown in Figure 1, the injection mold that is used for the forming double-layer double-color goods in the present embodiment has comprised the basic structure of common plastic mould.As solid plate 1, moving platen 2 etc.Its difference is to have inlayed two dynamic model 2a side by side in moving platen 2, is provided with a cover half in the solid plate 1.The both sides of moving platen 2 are provided with linear pattern guide rail 3 along the orientation of two dynamic model 2a, the position corresponding with guide rail 3 is provided with the guide groove 2b with guide rail 3 tablings on the moving platen 2, moving platen 2 does reciprocating linear motion at the effect lower edge guide rail 3 of drive unit (for example hydraulic jack is not shown).Wherein the cylinder body of hydraulic jack can be installed on the mold base, and its push rod and moving platen 2 interconnect by contiguous block and get final product.Simultaneously, on guide rail 3 travel switch is set, travel switch is electrically connected with the control device of drive unit, is used to control the shift motion of moving platen 2, and it is corresponding with cover half exactly to make two dynamic model 2a to distinguish.The control device of hydraulic jack is connected by RCA with injection machine, the action moment of control hydraulic jack.Travel switch is connected with the same signal of hydraulic jack control device.Wherein drive unit is not limited to the drive unit of hydraulic pressure, can also be mechanical actuation device or manual driving device or blast drive unit etc.
In addition, in two dynamic models, wherein second dynamic model cooperates formed cavity dimension to be greater than first dynamic model and cooperates formed cavity dimension with cover half with cover half, thereby provides the space for the injection moulding second time.
Panel with computer casing is an example, how specifically to introduce on common plastic rubber panel injection moulding layer of transparent PMMA material and promote that product integral body is wear-resisting, the injection moulding process of anti-scratch performance: the mould that will be provided with two dynamic models is installed on the injection machine, and with the nozzle alignment of injection machine, after installing, moving platen can move by straight line under hydraulic jack effect bottom left right or up.First dynamic model cooperates formed die cavity gap to be less than second dynamic model and cooperates formed die cavity gap with cover half with cover half, the difference in its gap just in time equals the thickness of transparent PMMA layer.
Then at the top of solid plate 1 or the side load onto another group nozzle and (for example adopt the disclosed double color injection device of ZL01228678.8, at present similarly install very universal with it, therefore do not introduce its concrete structure in detail), second group of nozzle be connected with the control system of injection machine by RCA can control the grouping injection.Behind the first dynamic model 2a and cover half matched moulds, first group of normal injection of nozzle of injection machine, after pressurize and cooling, the first dynamic model 2a separates with cover half, and the matrix of computer panel is remained in the cover half.Hydraulic jack drives moving platen 2 straight lines and moves to second dynamic model and the corresponding position of cover half then, the beginning matched moulds, this moment second group of nozzle injection, at the PMMA protective layer of the surface formation layer of transparent of the matrix of electric computer panel.After pressurize and the cooling, second dynamic model and cover half die sinking make the computer panel of moulding remain on second dynamic model.From second dynamic model take off product by the action of ejector retainner plate, post rod mechanism or the operation of manipulator (deciding on concrete product structure) this moment; thereby obtain having the computer panel of base layer and two kinds of different colours of protective layer and material, realize whole double-layer bi-color injection moulding.
Conversely, when adopting two cover half to match with a dynamic model, the action in injection moulding process also is the same.Their difference is, when first time die sinking, the matrix of computer panel remains on the dynamic model.Their common ground is in die sinking first time process, and ejector retainner plate, the post rod mechanism of injection machine all are failure to actuate, and moving platen or solid plate straight line move then, the secondary matched moulds.After the die sinking second time, ejector retainner plate, post rod mechanism are just looked the concrete condition action.In the actual production process, specifically select two dynamic models, two cover half that match with a cover half still to match with a dynamic model and decide on the concrete structure of wanting shaped article.
