In impression bolster 10；11 bottom of cavity plate is welded with support plate 18.
Further：The middle part of the solid plate 1 is provided with main core channel, and the bottom of solid plate 1, which is equipped with, tilts bracket 1-
1。
Further：There is external screw thread in 4 upper end of the side core；4 bottom end of side core is cheese head, cheese head lower end side
Face is inclined-plane.
Further：The center of the gear 5 is equipped with endoporus.
Further：6 middle part of the rack nut is equipped with internal thread.
Further：The screw shaft 7 is equipped with external screw thread；7 one end of screw shaft is equipped with socket cap, and socket cap is located at cover half
In plate 1.
Further：Guide-track groove 11-1 is equipped in the cavity plate 11；It is additionally provided with release link channel in cavity plate 11 and pushes away
Bar channel.
A kind of Novel threaded side core-pulling injection molding of the present invention, its 6 centre of rack nut is threaded hole, appearance
Face side is rack；There is external screw thread on 4 top of side core, and the externally threaded screw pitch is consistent with the side threaded hole screw pitch of plastic, to
It is molded the side threaded hole of plastic；4 other end of side core is cylinder head, and there is an inclined-plane in head lower end；Phase is also arranged at 1 bottom of solid plate
Corresponding inclined-plane；Two bevel inclination angles are identical, and when mold closing contacts with each other fitting；Spring 9 is assemblied in the cylinder head of side core 4
Between cavity plate 11.Side core 4 and the key connection of gear 5；Side core 4 is that gear pair connects with gear 5；6 He of rack nut
Screw shaft 7 is to be threadedly coupled；Rack nut 6 is located in the track groove in cavity plate 11；A kind of Novel threaded side core-pulling of the present invention
Injection molding makes side core 4 rotate when it is molded from the die joint of impression bolster 10 and solid plate 1 using rack and pinion mechanism
And movement, so that screw thread side core 4 is demoulded from the side threaded hole of plastic and come out, completes Leave out thread action, have to mold
The plastic of side threaded hole.
The specific screw thread side core-pulling course of work：
It is molded by the die joint of impression bolster 10 and solid plate 1 after plastic parts moulding, when die sinking, 6 sliding tooth of rack nut
5 rotation of wheel, drives the rotation of side core 4 and movement, completes Leave out thread action, and support plate 18 and compressed spring 9 constitute side core 4
Positioning device makes the top of the cylinder head lower end plane and fagging 18 of side core 4 under the action of spring force and support plate 18
It fits, keeps in place, the inclination bracket 1-1 phases on the inclined-plane of side core 4 and 1 bottom of solid plate when to mold
Mutually fitting, to realize the smooth reset of side core 4.
A kind of Novel threaded side core-pulling injection molding of the present invention, its course of work：
It is molded by the die joint of impression bolster 10 and solid plate 1 after plastic parts moulding, sees Fig. 2, cavity plate 11, type when die sinking
Chamber fixed plate 10, Bottom clamp plate 17 are moved to the left, and drive side core 4 and gear 5 to be moved to the left together, solid plate 1, cover half are fixed
Plate 2, main core 3 are motionless, and screw shaft 7 and rack nut 6 are also motionless；To which the section of rack driving gear 5 on rack nut 6 revolves
Turn, drives 4 synchronous rotary of side core, side core 4 to be displaced outwardly while rotating, complete the core pulling action of lateral threaded hole；
The inclined-plane on 4 head of side core is slided and is progressively disengaged on the inclination bracket 1-1 of solid plate 1 at this time, until separating, after separating
Side core 4 is tightly attached under the action of 9 power of spring in the support plate 18 of cavity plate 11, and is maintained at this position, and die sinking terminates
Push plate fixed plate 16 moves right under the effect of external force later, drive push rod 14 also and then moves right, to by plastic from
It is released in cavity plate 11, completes the demoulding of entire plastic；When molding, the inclined-plane of side core 4 and the inclination bracket 1-1 of solid plate 1
Start to contact, side core 4 constantly overcomes 9 power of spring under the action of inclined-plane, moves inwards, completes to reset；Push rod 14 simultaneously
It is resetted under the action of release link 12；It is injected next time to wait for.
The present invention another innovative point be：As long as the side core 4 for replacing different screw pitch realizes the side of different screw pitch
Core pulling to threaded hole, therefore versatility is good, without re-replacing whole set of die；In addition side core-pulling is adjustable away from size, by setting
It counts structure and understands that the rack left side of rack nut 6 and the distance between the axis of side core 4 are bigger, then side core-pulling is away from more
Greatly, rack nut 6 can be rotated before assembly to axial position of the adjusting gear rack on screw shaft 7, after installing, moreover it is possible to
Using tool pass through rotate screw shaft 7 left-hand end so that rack nut 6 can left and right small distance movement, so as to adjust
The distance between the axis of rack left side and side core 4, in this way can be with the distance of more precise control core pulling.
A kind of Novel threaded side core-pulling injection molding of the present invention, it makes side in die sinking using rack and pinion mechanism
Core rotates and movement, so that side core is demoulded from the side threaded hole of plastic and comes out, and completes Leave out thread action, to which molding is provided
There is the plastic of side threaded hole；It realizes that synchronous side core-pulling, working efficiency are greatly improved in die sinking, and simple in structure, makes
With conveniently, additionally it is possible to be suitable for the core pulling of the lateral threaded hole of various screw pitch and side core-pulling is away from adjustable.
The above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application range,
The equivalent change or modification that feature and principle are done, is included within the scope of present patent application.
