The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, this is preferred embodiment of the present utility model.
Embodiment one.
Such as Fig. 1～shown in Figure 4, a kind of double-color mold that advances the plastic structure improvement of present embodiment, comprise the double-color mold body, the double-color mold body comprises male model 1 and the master mold 2 that is used with male model 1, described master mold 2 tops are provided with die cavity 21, described male model 1 offers the injection molding hot flow path 11 of ebonite, described master mold 2 offers the injection molding side of flexible glue and enters solation road 3, described hot flow path 11 and described side are entered solation road 3 and are communicated with described die cavity 21 respectively, and described master mold 2 belows are provided with the ejecting structure that is used with described die cavity 21.Wherein, described side is advanced the end that solation road 3 comprises sprue 31 and 32, three branch flow passages 32 of three branch flow passages and is communicated with described sprue 31 respectively, and the other end of three branch flow passages 32 is communicated with described die cavity 21 respectively.Wherein, described die cavity 21 comprises that being provided with 213, three described branch flow passages 32 of rib between the first cavity 211 and the second cavity 212, the first cavitys 211 and the second cavity 212 is communicated with respectively the first cavity 211, the second cavity 212 and rib 213.
During use, first with male model 1 and master mold 2 relative matched moulds, the ebonite of melting is injected from the glue-feeder of hot flow path 11, the melting ebonite enters in the die cavity 21 of master mold 2, form product ebonite layer, then with male model 1 and master mold 2 split cavity mutually, the glue-feeder that advances the sprue 31 in solation road 3 in side injects the melting flexible glue, the melting flexible glue injects respectively the position of die cavity 21 corresponding the first cavitys 211, the second cavity 212 and rib 213 by three branch flow passages 32, mold product flexible glue layer at product ebonite layer, after the flexible glue cooling, namely finish the product injection moulding.After injection moulding is finished, utilize ejecting structure that product is ejected die cavity 21, conveniently product is taken out.Ebonite advances the glue injection moulding by different runners respectively with flexible glue, guarantee that mould advances the glue balance, be partial to a side when being conducive to avoid the flexible glue injection moulding, thereby the ebonite rib of effectively avoiding die cavity 21 to be used for moulding suffers oppression and opposite side is swung in bending, improve the qualification rate of injecting products, the product appearance quality is good.
Three described branch flow passages 32 of present embodiment and the junction of described sprue 31 are respectively arranged with choke valve 5, be convenient to accurately control advancing the glue amount and advancing glue speed of three branch flow passages 32, be conducive to control rib 213 both sides and advance the glue balance, strengthen injection moulding effect of the present utility model.
Three described branch flow passages 32 of present embodiment all are positioned at described die cavity 21 the same sides, are convenient to machine-shaping, reduce the flow channel length of branch flow passage 32, and that improves flexible glue advances glue speed, and injection moulding is effective, enhances productivity.
The bottom of the master mold 2 of present embodiment is provided with sprue puller 7, and sprue puller 7 enters solation road 3 with described side and is used.Particularly, sprue puller 7 is arranged at the glue-feeder of sprue 31 movably, and during the die sinking of double-color mold body, sprue 31 solidifying material inject respectively die cavity 21 from three branch flow passages 32 under the effect of sprue puller 7, guarantee that three branch flow passages 32 advance the glue balance.
Be provided with telescopic backstay 8 between the male model 1 of present embodiment and the master mold 2, when being convenient to the die sinking of double-color mold body and matched moulds, avoid male model 1 and master mold 2 in the process of relatively moving, to be offset, improve the dependability of product.
Embodiment two.
As shown in Figures 2 and 3, the difference of present embodiment and embodiment one is that the periphery of the die cavity 21 of present embodiment is provided with overflowing well 6.
Because the coating product power of double-color mold body is in master mold 2 sides, so in theory after the die sinking, product can be attached on the master mold 2, so then unfavorable product takes out, so do a plurality of overflowing well 6 at the product periphery, overflowing well 6 can be held product and be attached to male model 1 when making die sinking, and the convenient product that takes out improves working (machining) efficiency.
The overflowing well 6 of present embodiment comprises brace 61 and angled slide block, and angled slide block is connected with the bottom surface of described brace 61, and described brace 61 is connected with described die cavity 21.Particularly, the length of the end that brace 61 is connected with the edge of die cavity 21 is greater than the length of brace 61 away from an end of die cavity 21, angled slide block is truncated cone-shaped, the surface area that angled slide block links to each other with brace 61 is less than the surface area of angled slide block away from brace 61, be convenient to after formed product ejects, directly overflowing well 6 broken off with the fingers and thumb disconnected getting final product, be convenient to following process, reduce manufacturing procedure, improve working (machining) efficiency.
The ejecting structure of present embodiment comprises thimble 4 and is used for driving the actuating unit of thimble 4 that the equal correspondence in the below of each described overflowing well 6 is provided with described thimble 4.Thimble 4 is arranged at overflowing well 6 belows, thimble 4 can eject master mold 2 with overflowing well 6 under the effect of power-driven mechanism, this moment, product together was attached to male model 1 side with overflowing well 6, this moment, overflowing well 6 can produce the thimble impression with the contact site of thimble 4, after taking out product, overflowing well 6 removals are got final product, avoid product surface the thimble seal to occur, be conducive to the improving product outward appearance.
The remainder of present embodiment is identical with embodiment one, repeats no more here.
Should be noted that at last; above embodiment is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; although with reference to preferred embodiment the utility model has been done to explain; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
