The specific embodiment
In order to describe technology contents of the present utility model, structural feature in detail, below in conjunction with embodiment and coordinate accompanying drawing to be described further.
Refer to Fig. 1 to Fig. 5, the mould 100 of the de-screw thread of interlock of the present utility model comprises thread core group 10, the de-thread mechanism 50 of interlock and lamination arranges mutually cover half 20 and dynamic model 30.Thread core group 10 is located between cover half 20 and dynamic model 30 and three forms forming cavity 40 jointly, for the desired plastic products of moulding, uses.Thread core group 10 comprises thread core 11 and side action sliders 12, side action sliders 12 is slided along the die sinking direction (being the direction of arrow B indication in Fig. 1) that crisscrosses cover half 20 and dynamic model 30 is located at the one in dynamic model 30 and cover half 20, particularly, in the present embodiment, side action sliders 12 is being located on dynamic model 30 of sliding, more preferably make the glide direction of side action sliders 12 mutually vertical with folding mould direction (being direction and the rightabout of arrow B indication in Fig. 1), for example, in Fig. 1, folding mould direction is to arrange along the above-below direction of dynamic model 30, the glide direction of side action sliders 12 is to arrange along the left and right directions of dynamic model 30 or fore-and-aft direction, make folding mould direction mutually vertical with the glide direction of side action sliders 12, to carry out better the object of side core-pulling start.
Cover half 20 is provided with Angle Pin 21, and Angle Pin 21 is stretching in side action sliders 12 of cooperation, and when folding mould, drives side action sliders 12 to slide; Particularly, in the present embodiment, Angle Pin 21 is the setting of inclination along die sinking direction, be preferably, one end that Angle Pin 21 stretches in side action sliders 12 is the centerline away from mould 100 of the present utility model, one end that Angle Pin 21 is arranged on cover half 20 is the centerline near mould 100 of the present utility model, thereby makes the Angle Pin 21 can be more reliably and drive accurately side action sliders 21 to slide.
Thread core 11 is being placed through in side action sliders 12 of pivotable along the glide direction of side action sliders 12, and thread core 11 has the end of thread 111 stretching in forming cavity 40 and the installation end 112 that is positioned at the end of thread 111 opposition sides.Driving tooth bar 51 and travelling gear 52 that the de-thread mechanism 50 of interlock comprises intermeshing transmission, travelling gear 52 is arranged on installation end 112, drive tooth bar 51 to be arranged on the cover half 20 or dynamic model 30 with Angle Pin 21, be mounted on cover half 20, preferably to make to drive tooth bar 51 to be arranged along the direction (being direction and the rightabout of arrow B indication in Fig. 1) of folding mould, so that drive tooth bar 51 can order about more reliably travelling gear 52 rotations in folding mold process, by the travelling gear 52 rotating, drive thread core 11 rotations again, thereby reach the object of de-screw thread.
Will be understood that, in other embodiments, side action sliders 12 is slidedly arranged on cover half 20, Angle Pin 21 is arranged on dynamic model 30, the same can realization in folding mold process orders about by Angle Pin 21 object that side action sliders 12 is slided.More specifically, as follows:
Compared with the superior, in the present embodiment, dynamic model 30 has fixed support plate 31, installation end 112 is being placed through on fixed support plate 31 of pivotable, travelling gear 52 is positioned at the outside of fixed support plate 31 along the glide direction of side action sliders 12, so that the mounting arrangements of thread core 11, and travelling gear 52 is provided a supporting role.Will be understood that, in other embodiments, when side action sliders 12 is slidedly arranged on cover half 20, fixed support plate 31 now is just followed side action sliders 12 and is arranged in the lump on cover half 20.
Simultaneously, the de-thread mechanism 50 of interlock also comprises the first idler gear 53, the first idler gear 53 is articulated on fixed support plate 31 and is corresponding with travelling gear 52, and the first idler gear 53 respectively with drive the transmission that is meshed of tooth bar 51 and travelling gear 52, so that drive tooth bar 51 to go to order about the rotation of travelling gear 52 by the first idler gear 53, to reach the object that drives tooth bar 51 to order about travelling gear 52 rotations, and there is the accurate and reliable advantage of transmission.Yes more excellent, in the present embodiment, thread core 11 may be selected to be four, but not as limit, four thread cores 11 are separated from each other and are parallel to each other, and 11 pairs of each thread cores should have an engaged transmission in a travelling gear 52, the first idler gears 53 and four travelling gears 52; The de-thread mechanism 50 of interlock also comprises the linkage gear 54 between four travelling gears 52, linkage gear 54 be articulated in fixed support plate 31 and with each travelling gear 52 engaged transmission, so that drive tooth bar 51 to go to order about 52 rotations of a travelling gear by the first idler gear 53, by linkage gear 54, go to drive three remaining travelling gears 52 to do the rotation of synchronizeing in the same way and coordinating with that travelling gear 52 above again, thereby reach, reliably take off accurately screw thread object.
Finally, side action sliders 12 has one first inclined-plane 121 away from a side of forming cavity 40, cover half 20 has the second inclined-plane 22 coordinating with the first inclined-plane 121, with the cooperation by the first inclined-plane 121 and the second inclined-plane 22, order about accurately side action sliders 12 resets, thereby guarantee the accurate and quality of moulded plastic products.
By reference to the accompanying drawings, principle to the mould of the de-screw thread of the utility model interlock describes: during the demoulding, injection machine orders about dynamic model 30 and moves and separate mutually with cover half 20 along the direction of arrow B indication in Fig. 1, the side action sliders 12 on dynamic model 30 is slided along the direction away from forming cavity 40 under the effect that is installed on the Angle Pin 21 on cover half 20, meanwhile, be arranged on driving tooth bar 51 on cover half 20 and order about the first idler gear 53 rotations because of moving of dynamic model 30, by the first idler gear 53 rotating, order about again a rotation in four travelling gears 52, again by that travelling gear 52 rotating by linkage gear 54 drive three remaining travelling gears 52 do synchronous in the same way and the rotation of coordinating, thereby realize order about each thread core 11 do synchronous in the same way and the rotation of coordinating, to reach reliably the object of the demoulding accurately.
Compared with prior art, by coordinating of driving tooth bar 51 of the present utility model and travelling gear 52, and the coordinating of Angle Pin 21 and side action sliders 12, therefore do in the die sinking process coordinating at cover half 20 and dynamic model 30, when Angle Pin 21 drives side action sliders 12 to slide toward the direction away from forming cavity 40, drive tooth bar 51 also by travelling gear 52, to drive thread core 11 rotations, realize the slip of side action sliders 12 and synchronizeing of thread core 11 rotations, to reach the object of the demoulding, therefore, the mould 100 of the de-screw thread of the utility model interlock has simple in structure, the advantage that cost is low and reliable and stable.
Above disclosed is only preferred embodiments of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
