1。
Further：There is external screw thread the upper end of the side core 4；The bottom of side core 4 is cheese head, cheese head lower end side
Face is inclined-plane.
Further：The center of the gear 5 is provided with endoporus.
Further：The middle part of the rack nut 6 is provided with internal thread.
Further：The screw shaft 7 is provided with external screw thread；The one end of screw shaft 7 is provided with socket cap, and socket cap is located at cover half
In plate 1.
Further：Guide-track groove 11-1 is provided with the cavity plate 11；Release link passage is additionally provided with cavity plate 11 and is pushed away
Bar passage.
A kind of Novel threaded side core-pulling injection molding of the present invention, is screwed hole, appearance in the middle of its rack nut 6
Face side is tooth bar；There is external screw thread on the top of side core 4, and the externally threaded pitch is consistent with the side screwed hole pitch of plastic, is used to
It is molded the side screwed hole of plastic；The other end of side core 4 is cylinder head, and there is an inclined-plane head lower end；Phase is also arranged at the bottom of solid plate 1
Corresponding inclined-plane；Two bevel inclination angles are identical, and contact with each other laminating during mold closing；Spring 9 is assemblied in the cylinder head of side core 4
And cavity plate 11 between.Side core 4 and gear 5 are connect with being bonded；Side core 4 and gear 5 are gear pair connection；The He of rack nut 6
Screw shaft 7 is threaded connection；Rack nut 6 is located in the rail groove in cavity plate 11；A kind of Novel threaded side core-pulling of the present invention
Injection molding, it rotates side core 4 when being molded from the die joint of impression bolster 10 and solid plate 1 using pinion and rack
And movement, the demoulding from the side screwed hole of plastic of screw thread side core 4 out, is completed Leave out thread action, have so as to mold
The plastic of side screwed hole.
The specific screw thread side core-pulling course of work：
Molded by the die joint of impression bolster 10 and solid plate 1 after plastic parts moulding, during die sinking, the drive gear 5 of rack nut 6 revolves
Turn, drive side core 4 to rotate and move, complete Leave out thread action, supporting plate 18 and compression spring 9 constitute the positioning of side core 4
Device, in the presence of spring force and supporting plate 18, the cylinder head lower end plane and the top of fagging 18 for making side core 4 are affixed
Close, holding is gone up in place, and the inclined-plane of side core 4 is mutually pasted with the inclination bracket 1-1 of the bottom of solid plate 1 during so as to matched moulds
Close, so as 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：
Molded by the die joint of impression bolster 10 and solid plate 1 after plastic parts moulding, see Fig. 2, cavity plate 11, die cavity is solid during die sinking
Fixed board 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 fixed plate 2,
Main core 3 is motionless, and screw shaft 7 and rack nut 6 are also motionless；So as to the section of rack drive gear 5 on rack nut 6 rotates,
The synchronous rotary of side core 4, side core 4 is driven to rotate while being displaced outwardly, the core pulling for completing lateral screwed hole is acted；Now
The inclined-plane of the head of side core 4 is slided and progressively disengaged on the inclination bracket 1-1 of solid plate 1, until separating, the side type after separating
Core 4 is close in the supporting plate 18 of cavity plate 11 in the presence of the power of spring 9, and is maintained at this position, after die sinking terminates
Push pedal fixed plate 16 moves right in the presence of external force, drives push rod 14 also and then to move right, so as to by plastic from die cavity
Released in plate 11, complete the demoulding of whole plastic；During matched moulds, the inclined-plane of side core 4 starts with the inclination bracket 1-1 of solid plate 1
Contact, side core 4 constantly overcomes the power of spring 9, moves inwards in the presence of inclined-plane, completes to reset；Push rod 14 is also multiple simultaneously
Resetted in the presence of the bar 12 of position；Injected next time so as to wait.
Another innovative point of the invention is：As long as changing the side core 4 of different pitch can just realize the side of different pitch
To the core pulling of screwed hole, therefore versatility is good, without re-replacing whole set of die；Other side core-pulling is adjustable away from size, by setting
Meter structure understands that the tooth bar left surface of rack nut 6 is bigger with the distance between the axis of side core 4, then side core-pulling is away from more
Greatly, rack nut 6 can be rotated before assembling so as to axial location of the adjusting gear rack on screw shaft 7, after installing, moreover it is possible to
Using instrument by rotating the left-hand end of screw shaft 7 so that rack nut 6 can be with the movement of left and right small distance, so as to adjust
The distance between axis of tooth bar left surface and side core 4, so 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 pinion and rack
Core is rotated and mobile, side core demoulding from the side screwed hole of plastic out, Leave out thread action is completed, so as to be molded provide
There is the plastic of side screwed hole；It realizes synchronous side core-pulling in die sinking, and operating efficiency is greatly improved, and simple structure, is made
With convenient, additionally it is possible to suitable for the lateral screwed hole of various pitch core pulling and side core-pulling away from adjustable.
The above is only better embodiment of the invention, therefore all constructions according to described in present patent application scope,
The equivalent change or modification that feature and principle are done, is included in the range of present patent application.
