Detailed description of the invention

In order to deepen understanding of the present utility model, below in conjunction with drawings and Examples, this utility model is done Describing in further detail, this embodiment is only used for explaining this utility model, not to protection of the present utility model Scope constitutes restriction.

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, right side Quiet mould 2, intermediate die 3, differential die opening mechanism 4, glue filling nozzle 5 and push rod 6；On described left side dynamic model 1 Half portion and lower half are each provided with lid formation die core 11；Described lid formation die core 11 is provided with lid type Chamber 12；Described lid formation die core 11 is additionally provided with secondary injection gluing mechanism 13；Described secondary injection gluing mechanism 13 Including 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 and the end of shortening 133 Corresponding；Described lower wedge 135 is fixed on slide plate 137；Described slide plate 137 is driven by oil cylinder 138；Institute State right side dynamic model 2 first half and lower half is each provided with box formation die core 21；Described box formation die core 21 In be provided with box die cavity 22；Described differential die opening mechanism 4 is arranged in intermediate die；Described differential die-sinking machine Structure 4 includes quiet mould tooth bar 42, dynamic model tooth bar 41, the gear wheel 44 being coaxially fixed in intermediate die and little tooth Wheel 43；One end of described quiet mould tooth bar 42 is fixed with the quiet mould in right side 2；One end of described dynamic model tooth bar 41 with Left side dynamic model 1 is fixed；Described quiet mould tooth bar 42 is engaged with gear wheel 44；Described dynamic model tooth bar 41 and little tooth Wheel 43 occlusion；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；Institute State lid die cavity 12 and the symmetrical distribution of box die cavity 22, be respectively distributed a pair；Institute Stating slide plate 137 when driving lower wedge 135 to be moved to the left, contracting core 132 is downward under the effect of upper wedge 134 Motion, shortening 133 is then along the gradient downward actuation of little wedge groove 136, and the operating distance of shortening 133 is more than contracting The operating distance of core 132.

Happy button box as shown in Figure 6 and lid, owing to box is higher than lid, the opening of mould will be with relatively A high product is as the criterion, but product requirement in-mold label, it is necessary to strengthen opening again, but forming machine Die sinking, apart from limited, needs again to reduce the opening of mould, it is necessary to reduce the opening of the mould of lid side, Adding the opening of the mould of big box side, the mould opening thus making both sides is different, the present embodiment The differential die opening mechanism used, when size gear revolves and turns around simultaneously, the dynamic model tooth engaged with little gear 43 The displacement of bar is much smaller than the displacement of the quiet mould tooth bar engaged with gear wheel, it is achieved that both sides The differential die sinking of mould；Then there is a circle flexible glue in the lid of happy button, seal, need the mould can be real Existing secondary injecting glue, the present embodiment have employed secondary injection gluing mechanism, and after one time injecting glue terminates, contracting core and shortening are wanted Rollback, concedes space to secondary injecting glue, and contracting core retraction stroke is that the glue of secondary injecting glue is thick, shortening retraction stroke For glue thickness and an injecting glue glue thickness sum of secondary injecting glue, now, the end face of shortening and contracting core flushes, and passes through Glue is injected in die cavity by the gum-injecting port of the secondary injecting glue that shortening rollback is reserved so that outward appearance light Shunping County of product Sliding, oil cylinder pulls slide plate, and slide plate drives lower wedge translation, the upper wedge drive downward rollback of contracting core, and shortening The then little downward rollback of wedge groove along lower wedge so that the distance of shortening rollback is more than the distance of contracting core 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 folds mould mould with lid, and two pairs of boxes and lid can be disposably made in employing, Owing to molding technique parameter is consistent so that box can well interworking with lid；Use differential die opening mechanism, open During mould, owing to the stroke of little gear is short, the stroke of gear wheel is long so that the tooth bar fixing with left side dynamic model moves The distance that the tooth bar that dynamic distance is fixed relative to mould quiet with right side moves is short, it is possible to achieve different distance Die sinking, can allow the die sinking of lid side apart from little, and the die sinking distance of box side is big, overcomes folded mould not Adapt to the defect of happy button box and the die sinking mode of lid, improve production efficiency and the quality of production.

Above-described embodiment should not in any way limit this utility model, all employing equivalents or equivalency transform The technical scheme that obtains of mode all fall within protection domain of the present utility model.
