It is threadedly coupled to screw rod 12 with horizontal tooth bar nut 14, horizontal tooth bar nut 14 is connect with 11 V-shaped guide rail of side core, clockwise
Or rotating counterclockwise transverse screw 12 will drive horizontal tooth bar nut 14 to move left and right；Push rod 5 is positioned by convex shoulder, is fixed on and is pushed away
In bar fixed plate 7 and push plate 8, ejector pin retaining plate 7 and push plate 8 are fixed together with screw.
A kind of injection mold of rack-and-pinion side core-pulling of the present invention, its specific side core-pulling course of work are：
When die sinking, mold is shown in Fig. 3 from die joint parting：Top clamping plate 1, fixed link 9, vertical screw rod 16 and vertical rack
Nut 17 is motionless, and plastic, cavity plate 2, moving platen 4 and Bottom clamp plate 6 retreat together, and duplicate gear 15 also follows moving platen 4 one
It rises and moves down, the first gear 15-1 in duplicate gear 15 is contacted with the right side section of rack of vertical rack nut 17, is formed
Gear pair connects, at this time when moving platen 4 continues past move down, effect of the duplicate gear 15 in 17 right side rack of vertical rack nut
Under rotate clockwise, due in duplicate gear 15 second gear 15-2 and the lower end section of rack of horizontal tooth bar nut 14 nibble
It closes, to drive horizontal tooth bar nut 14 to move right, so that side core 11 is same by the connection of transverse screw 12 and cover board 13
Step moves right, and completes side core-pulling；After side core-pulling, push plate 8 rises under external force, and driving push rod 5 to rise will modeling
Part 3 is deviate from from cavity plate 2, completes stripping action, sees Fig. 4.
A kind of injection mold of rack-and-pinion side core-pulling of the present invention, its feature also reside in side core-pulling away from can
Adjust, by side core-pulling known to design structure away from length it is i.e. adjustable by the position for controlling horizontal tooth bar nut 14, molding
Before, rotation transverse screw 12 is first passed through, changes the position of horizontal tooth bar nut 14, rotates clockwise transverse screw 12, make transverse direction
Rack nut 14 moves right, and rotation counterclockwise laterally turns screw rod 12, so that horizontal tooth bar nut 14 is moved to the left, to change core pulling
Distance realizes that Core-pulling distance is adjustable.
A kind of injection mold of rack-and-pinion side core-pulling of the present invention, its another bright spot are to may be implemented to prolong
When core pulling, and delay time can adjust, determined by the position of vertical rack nut 14 by delay time known to design structure,
The delay time that the position of vertical rack nut 14 is lower and the occlusion of duplicate gear 15 needs is longer, otherwise shorter, before molding
Pass through vertical screw rod 16 clockwise or counterclockwise, you can making vertical rack nut 17, vertically screw rod 16 moves up and down, from
And change the delay core pulling time, realize the adjustable of delay time.
A kind of injection mold of rack-and-pinion side core-pulling of the present invention, it uses a kind of novel gear-tooth item
The characteristics of core-pulling mechanism, this mechanism is that the big feature of rack-and-pinion taking out force is not only utilized, but also Core-pulling distance and side core-pulling
Time is designed adjustable.In addition, it can also be realized just completes side core-pulling function in die sinking, and Core-pulling distance is adjustable；It
The time has been saved, has increased production efficiency, and simple in structure.
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.
