The utility model has the advantage that two materials are in injection molding in a mold so as to decrease the manufacturing cost of the mold, shorten the production cycle and increase the production efficiency; and the product has strong adhesive force and low rejection ratio.
Description
Technical field:
The utility model relates to a kind of injection molding material mould, specifically is a kind of two material injection molding material moulds that can inject two kinds of different colours or unlike material in a mould.
Background technology:
Different parts and in its joint portion the mutually combine moulding of the material that two material injection mouldings are meant two kinds of different colours or unlike material in a product is a whole product.Such as, the middle part of a product is hard material and the edge is two kinds of plastic materials that soft material just need inject different hardness at these two different parts.For the production of the plastic product of this polychrome or many materials, at present adopt two kinds of methods more:
The one, adopt twice forming method, this method need be used two molds, when first kind of material after the first mold injection moulding, again with its just type move to and inject second kind of material in second mold, through behind the quadric injection mould, product just can be molded into a complete product.This method does not need special double coloured plastic injection machine, can finish on monochromatic injection machine, but its defective is, need two secondary moulds, increased the Mold Making cost, simultaneously, the binding site merging precision of two kinds of unlike materials of its product is also poor, and adhesive strength is poor, and product is more coarse.
Also has a kind of rotary die one-step moulding method that is to use, this method is the injection mouldings on a special injection machine of two kinds of unlike materials, its mould is to adopt moving-mould-core of two groups of die cavities and two to overlap independently screw rod control system, its crucial technology is that moving platen is provided with a rotatable rotating disk, moving-mould-core is arranged on the rotating disk, rotating disk is controlled by the screw rod control system, when first material of product injecting for the first time on the mold cavity I finish after, moving-mould-core is in the drive backspin turnback of rotating disk, moving-mould-core forwards the position of die cavity II to from die cavity I, behind the matched moulds, carry out the injection of second material again at die cavity II.This forming method, the mould structure complexity, the Mold Making difficulty is big, has increased the Mold Making cost, and the cohesive force of two kinds of material binding sites of product is little, intensity difference, tear easily two kinds of material junctions.And this injection moulding process is general only to adapt to the undersized product of production, and larger-size product just is difficult to finish, thereby makes the production capacity of equipment fail to obtain performance.
The utility model content:
The technical problems to be solved in the utility model is at defective and the deficiency that above-mentioned prior art exists, to provide a kind of and can finish two material injection molds that two kinds of different materials inject in a secondary mould.
Technical solution of the present utility model is that a kind of two material injection molds with following structure are provided.
A kind of pair of material injection mold, comprise cope match-plate pattern, stripper plate, cavity plate, swaging die, moving platen, moving-mould-core, fixed head, lower bolster and oil cylinder, it is characterized in that, in cavity plate, be provided with A, B injection hole and A, B hot flow path, swaging die is provided with A die cavity and Type B chamber, in moving-mould-core, be provided with the lock pin chock, be provided with gap in the joint portion in A die cavity and Type B chamber for the turnover of lock pin chock.
The lower surface of described lock pin chock is provided with oblique lock dog, and tiltedly lock dog is arranged in the fixed head, and tiltedly lock dog is connected with oil cylinder.
After adopting above structure, compared with prior art, the utlity model has following advantage: because the utility model is provided with A in cavity plate, B injection hole and A, the B hot flow path, swaging die is provided with A die cavity and Type B chamber, in moving-mould-core, be provided with the lock pin chock, when injecting the A material by A injection hole and A hot flow path, the lock pin chock is inserted to the binding site in A die cavity and Type B chamber, blocking-up A material injects to the Type B chamber, after treating that the A material is filled with the A die cavity, by oil cylinder the lock pin chock is withdrawed from a segment distance, remove the obstruct of A die cavity and joint portion, Type B chamber, inject the B material by B injection hole and B hot flow path to the Type B chamber again, treat A, two kinds of materials of B are fully after in-molded, shaped article is taken out in die sinking.Therefore, the utility model is finished the injection mo(u)lding of two kinds of different materials a special injection moulding and in one pair of mould, thereby reduces the Mold Making cost, has shortened the production cycle, has improved production efficiency, and the product bonding force is strong, and percent defective is low.
Description of drawings:
Fig. 1 is the two material injection mold structure schematic diagrames of the utility model.
Shown in the figure: 1, cope match-plate pattern, 2, stripper plate, 3, cavity plate, 4, moving platen, 5, fixed head, 6, lower bolster, 7, oil cylinder, 8, the A injection hole, 9, the B injection hole, 10, the lock pin chock, 11, oblique lock dog, 12, backing plate, 13, the mould pin, 14, go up ejector retainner plate, 15, ejector retainner plate down.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in the accompanying drawing, the two material injection molds of the utility model, comprise cope match-plate pattern 1, stripper plate 2, cavity plate 3, swaging die (not shown), moving platen 4, moving-mould-core (not shown), fixed head 5, lower bolster 6 and oil cylinder 7, in cavity plate 3, be provided with A, B injection hole 8,9 and A, B hot flow path (not shown), swaging die is provided with A die cavity and Type B chamber (not shown), in moving-mould-core, be provided with lock pin chock 10, be provided with gap in the joint portion in A die cavity and Type B chamber for the turnover of lock pin chock; Be provided with oblique lock dog 11 in the lower surface of lock pin chock 10, tiltedly lock dog 11 is arranged in the fixed head 5, and tiltedly lock dog 11 is connected with oil cylinder 7, also be provided with between fixed head 5 and the lower bolster 6 mould pin 13, on ejector retainner plate 14 and following ejector retainner plate 15.
During use, the two material injection molds of the utility model are installed on the double-shot moulding material machine, make the main injection nozzle of its A injection hole 8 correspondences at injection machine, B injection hole 9 correspondences are in the auxilliary injection nozzle of injection machine.After mould installs, matched moulds, by oil cylinder 7 lock pin chock 10 is inserted to binding site in A die cavity and Type B chamber, inject to the Type B chamber with blocking-up A material, start injection machine, earlier the A material is injected in the A die cavity, after treating that the A material is filled with the A die cavity, by oil cylinder 7 lock pin chock 10 is withdrawed from die cavity to the edge, remove the obstruct of A die cavity and joint portion, Type B chamber, the auxilliary injection nozzle by injection machine to Type B chamber injection B material, treats that two kinds of materials of A, B are fully after in-molded to B injection hole 9 and B hot flow path again, shaped article is taken out in die sinking.
