Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention being described in further detail, this embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limits.
Embodiment
As shown in Figures 1 to 5, the happy button box in 2+2 chamber mould mould folded with lid, it includes left side dynamic model 1, the quiet mould in right side 2, intermediate die 3, differential die opening mechanism 4, glue filling nozzle 5 and push rod 6；Described left side dynamic model 1 first half and lower half are each provided with lid formation die core 11；Described lid formation die core 11 is provided with lid die cavity 12；Described lid formation die core 11 is additionally provided with secondary injection gluing mechanism 13；Described secondary injection gluing mechanism 13 includes secondary glue filling nozzle 131, contracting core 132 and shortening 133；The top of described contracting core is lid die cavity 12；The end of described contracting core 132 is provided with wedge 134；Described upper wedge 134 is arranged on lower wedge 135；The upper surface of described lower wedge 135 is provided with little wedge groove 136；Described little wedge groove 136 is corresponding with the end of shortening 133；Described lower wedge 135 is fixed on slide plate 137；Described slide plate 137 is driven by oil cylinder 138；Described right side dynamic model 2 first half and lower half are each provided with box formation die core 21；Described box formation die core 21 is provided with box die cavity 22；Described differential die opening mechanism 4 is arranged in intermediate die；Described differential die opening mechanism 4 includes quiet mould tooth bar 42, dynamic model tooth bar 41, the gear wheel 44 being coaxially fixed in intermediate die and little gear 43；One end of described quiet mould tooth bar 42 is fixed with the quiet mould 2 in right side；One end of described dynamic model tooth bar 41 is fixed with left side dynamic model 1；Described quiet mould tooth bar 42 is engaged with gear wheel 44；Described dynamic model tooth bar 41 is engaged with little gear 43；Described push rod 6 one end is fixed on the quiet mould 2 in right side, and the other end is fixed with intermediate die 3；Described lid die cavity 12 and the symmetrical distribution of box die cavity 22, be respectively distributed a pair in a mold up and down；When described slide plate 137 drives lower wedge 135 to be moved to the left, contracting core 132 is at the moved downward of upper wedge 134, and shortening 133 is then along the gradient downward actuation of little wedge groove 136, and the operating distance of shortening 133 is more than the operating distance of contracting core 132.
As shown in Figure 6 happy button box and lid, owing to box is higher than lid, the opening of mould to be as the criterion with a higher product, but product requirement in-mold label, it is accomplished by strengthening again opening, but the die sinking of forming machine is apart from limited, need again to reduce the opening of mould, it is accomplished by reducing the opening of the mould of lid side, add the opening of the mould of big box side, the mould opening thus making both sides is different, the differential die opening mechanism that the present embodiment adopts, when size gear revolves and turns around simultaneously, the displacement of the dynamic model tooth bar engaged with little gear 43 is much smaller than the displacement of the quiet mould tooth bar engaged with gear wheel, achieve the differential die sinking of both sides mould；A circle flexible glue is then had in the lid of happy button, seal, mould is needed to be capable of secondary injecting glue, the present embodiment have employed secondary injection gluing mechanism, after one time injecting glue terminates, rollback is wanted in contracting core and shortening, space is conceded to secondary injecting glue, the glue that contracting core retraction stroke is secondary injecting glue is thick, shortening retraction stroke is that the glue of secondary injecting glue is thick in an injecting glue glue thickness sum, now, the end face of shortening and contracting core flushes, glue is injected in die cavity by the gum-injecting port of the secondary injecting glue reserved by shortening rollback, the outward appearance fairing making product smooths, oil cylinder pulls slide plate, slide plate drives lower wedge translation, upper wedge drives the downward rollback of contracting core, shortening is the little downward rollback of wedge groove along lower wedge then, make the distance distance more than contracting core rollback of shortening rollback, and then the end face of shortening and contracting core flushes after realizing rollback.
The happy button box in 2+2 chamber of the present embodiment mould mould folded with lid, employing disposable can make two pairs of boxes and lid, owing to molding technique parameter is consistent so that box can well interworking with lid；Adopt differential die opening mechanism; during die sinking; owing to the stroke of little gear is short; the stroke of gear wheel is long so that the distance that the tooth bar fixing with left side dynamic model moves is short relative to the distance that the tooth bar fixing with the quiet mould in right side moves, it is possible to achieve the die sinking of different distance; the die sinking of lid side can be allowed apart from little; the die sinking distance of box side is big, overcomes folded mould and does not adapt to the defect of happy button box and the die sinking mode of lid, improves production efficiency and the quality of production.
Above-described embodiment should not in any way limit the present invention, and the technical scheme that all employings are equal to replacement or the mode of equivalency transform obtains all falls within protection scope of the present invention.
