Beneficial effect: the internal thread automatic demoulding injection mould that the utility model provides, for the injection mould of plastic bottle closure, plastic outer surface is provided with straight burr flower can do spline position, and the solidifying material of cast cuts off and the demoulding automatically, substantially do not need artificial auxiliary and supervision, save human resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of internal thread automatic demoulding injection mould, comprise sprue bush 1, sprue 15, reservation plate 2, die joint 16, guide pillar 4, push piece plate 5, moving plate 11, push rod 14, also comprise thread core 3, rotating core 9, bearing 12, gear 13, described reservation plate 4 tops are provided with sprue bush 1; In described die joint 16, be provided with thread core 3; Thread core 3 both sides are provided with push piece plate 5; The interior rotating core 9 that arranges of described moving plate 11, described rotating core 9 arranged outside have bearing 12, and described bearing 12 one end are connected with rotating core 9, and the other end is connected with gear 13; Described push rod 14 is arranged in rotating core 9, for ejecting plastic; Within described guide pillar 4 runs through and is connected in reservation plate 2, die joint 16, moving plate 11.Also comprise and play ejector pin 6, spring 7, gag lever post 8, described bullet ejector pin 6, spring 7 are arranged in die joint 16, and spring 7 one end are connected with die joint 16 sidewalls, and the other end is connected with bullet ejector pin 6; Described guide pillar 4 sidewalls are provided with groove, for playing ejector pin 6 clampings; Described gag lever post 8, through within being connected in reservation plate 2, die joint 16, moving plate 11, is fixedly connected with guide pillar 4 lateral surfaces.
Also comprise hook material bar 10, described hook material bar 10 is through within being connected in reservation plate 2, die joint 16, moving plate 11, and hook material bar 10 tops are arranged in sprue 15, and hook material bar 10 bottoms are provided with snap ring, for clamping, live moving plate 11.
As preferred version, described sprue 15 ends are provided with oblique groove.
As preferred version, described rotating core 9 inner sides are provided with straight burr floral structure.
As preferred version, described thread core 3 bottom faces adopt point gate feeding form.
Specific embodiment is as follows: after injection moulding completes, during die sinking, mould, from A punishment type, drives rotating core 9 synchronous rotaries simultaneously, and plastic is screwed out from thread core 3.After moving plate 11 continues, move on to when playing ejector pin 6 and meeting with groove on guide pillar 4, after guide pillar 4 drives push piece plates 5, move, mould, from B punishment type, is broken pin-point gate aggregate deviate from.At this moment cast is solidifying expects under the drag effect of sprue 15 end oblique grooves, transfixion.When die sinking to be enough to make solidifying material to fall distance time, it is mobile that gag lever post 8 forces push piece plate 5 to stop.Moving plate 11 continues to retreat, and guide pillar semi-finals row is deviate from from play ejector pin 6, and pulls hook material bar 10 that the solidifying material of sprue 15 is pulled out from sprue bush 1.Meanwhile, due to the drag effect of oblique groove, make the solidifying material of runner produce crooked plastic deformation, and safety is deviate from from running channel.Ditch material bar 10 continues to retreat, and under the effect of push piece plate 5, the solidifying material of cast is deviate from by force from hook material bar 10, and automatically falls.After solidifying material Automatic-falling, push rod 14 ejects plastic, and automatically falls.
