The utility model is further illustrated in conjunction with the drawings and specific embodiments.
In conjunction with shown in Fig. 1 and Fig. 2, the injection mould with thread deep hole moulding production is used for this embodiment offers a kind of
Tool comprising upper mold 2 and lower die 3 further include having segmentation core-pulling mechanism on the injection mold, in this embodiment, the segmentation
Core-pulling mechanism include side slide block 5, slider core 6, hinge tooth motor 7 and two seat slider-actuated parts plate 4, wherein：
The upper side of the lower die 3 is equipped with a horizontal sliding rail, which can actively be set on the sliding rail, in turn
In lower die 3；Then, the slider core 6 and hinge tooth motor 7 are mounted on the side slide block 5 and can be lateral with this
Sliding block 5 moves together.
Specifically, the side slide block 5 is equipped with transmission component, in this embodiment, which is gear assembly,
The input gear and four output gears being sequentially connected with the input gear being installed on including one on 7 output shaft of hinge tooth motor
Wheel；In this embodiment, which has four, and each slider core 6 plugs and is fixed on the output gear
On, and be set to shaft core position, realize the slider core 6 can be rotatably arranged on the side slide block 5 and by gear assembly with
Tooth motor 7 is cut with scissors to be sequentially connected；Each output gear is identical as the input gear transmission ratio, and then realizes each slider core 6
It rotates synchronously.
The plate 4 is fixed in the upper mold 2, and is respectively arranged on two side positions of the side slide block 5；The corresponding side slide block
On 5 one side, which, which is equipped with, plays the cam rail 42 that cam pushes control action；The corresponding cam rail 42
The both sides of position, the side slide block 5 are respectively provided with an idler wheel 52, which can be rotatably arranged on the side slide block 5, to plug
In in the cam rail 42, and is driven and move by the plate 4.
In conjunction with Fig. 5, the cam rail 42 on the plate 4 is that downward and oblique outside tilts extension, and bottom is equipped with
Adapt to the opening of 52 width of idler wheel；In this embodiment, the upper edge of the cam rail 42 is provided at the upside of the idler wheel 52,
The idler wheel 52 is driven for being contradicted in clamping process, and then forms a molding driving portion 421；Likewise, the cam rail 42
Lower edge be set to the idler wheel 52 downside, for contradict in the process of die sinking drive the idler wheel 52, formed die sinking driving portion
422；Meanwhile the upper end of the cam rail 42 is additionally provided with an idle stroke track, specifically：The molding driving portion 421 and die sinking
The upper end of driving portion 422 is connected by a vertical connection wall 420, and then forms the idle stroke track extended vertically, i.e., in fact
Show in slider-actuated part, i.e. plate 4 molds on moving direction, shape between the molding driving portion 421 and the die sinking driving portion 420
At idle stroke track, to be used for slider-actuated part, i.e. plate 4, the gap of dry running.
In this embodiment, one end which deviates from the side slide block 5 is free end, and free end is formed
One inner core section, and the position that the inner core section is connected in the slider core 6 also forms a hinge tooth section, for forming thread；Due to
Pulling force can cause moulding to damage needed for hinge tooth reaction force deficiency support demoulding, and hinge tooth assisted group is additionally provided on side slide block
Part：The hinge tooth accessory part includes secondary spring 82 and spring pre-tightening set 81；In this embodiment, spring pre-tightening set 81 is
The cylindrical structure of one end open is closed in one end, which is pressing spring, is set in spring pre-tightening set 81, and one end
The open end of spring pre-tightening set 81 is protruded out, then, the open end of spring pre-tightening set 81 is equipped with back-off structure.
The side slide block 5 is equipped with mounting hole, and spring pre-tightening set 81 can be actively set on the side slide block 5, and be sealed
The one end closed can protrude out the side slide block, to compress the secondary spring 82, by the secondary spring 82 to the spring pre-tightening set
Applying one makes its end protrude out the side slide block active force, applies core pulling active force for the auxiliary during hinge tooth.
In conjunction with Fig. 1, Fig. 3 to Fig. 6, the die sinking process of the embodiment, mechanism action principle is as follows：
(1) matched moulds stage：Plate 4 contradicts idler wheel 52 by molding driving portion 421, and side slide block 5 is made to be in die-closed position,
Idler wheel 52 is set to the upper end of the cam rail 42 at this time, and contacts at the molding driving portion 421；
(2) stage is tentatively molded：Upper mold 2 moves up, and idler wheel 52 moves down along connection wall 420 and reaches die sinking driving portion relatively
422 upper ends, and then it is detached from molding driving portion 421 in the horizontal direction, to be pulled open in the horizontal direction with the molding driving portion 421
Cut with scissors the distance of tooth；
(3) tooth ejection phase is cut with scissors：Cutting with scissors tooth motor 7 drives slider core 6 to rotate, and side under the action of cutting with scissors tooth accessory part
To core pulling, i.e. side slide block 5 drives the translation in cam rail 42 of idler wheel 52, until hinge tooth is completed, idler wheel 52 contradicts molding and drives
Dynamic portion 421；
(4) stage is molded completely：Upper mold 2 continues to move up, and die sinking driving portion 422 moves up and contradict idler wheel 52, drives lateral
5 sidesway of sliding block, realizes complete core pulling.
In this embodiment, cam rail is integrated with molding driving portion and die sinking driving portion, it is to be understood that at it
In its specific implementation mode, molding driving portion and die sinking driving portion can also be set on different components, then be fixed on
Upper mold, as long as ensureing to be equipped between slider-actuated part dry running between the molding driving portion and the die sinking driving portion
Gap can be achieved with said mechanism operating principle process.
In this embodiment, the preliminary core pulling of side slide block is realized with hinge tooth motor and hinge tooth accessory part
, realization is then moved up by plate and is demoulded again；In other specific implementation modes, when not setting screw thread, the side slide block is also
Oil cylinder can be set, contradicted by oil cylinder and push the preliminary sidesway of side slide block, or side core_pulling etc. is rotated by oil cylinder,
Realize the utility model technique effect.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
