[0016] The present invention is described in detail below in conjunction with various implementation modes, but it should be noted that these implementation modes are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these implementation modes are all within the scope of protection of the present invention.

[0017] The utility model provides a rotary demoulding device, which can be applied to an injection molding device for a threaded cap and used in combination with an injection mold to assist in demoulding the threaded cap after injection molding. The utility model does not specifically limit the injection molding device, and those skilled in the art can adaptively install and debug the rotary demoulding device of the utility model according to actual conditions.

[0018] The utility model discloses a rotary demoulding device comprising: a rotary mechanism and at least one group of demoulding mechanisms; the rotary mechanism comprising: a screw and a transmission gear; the transmission gear is sleeved on the screw and can rotate with the axial movement of the screw; the demoulding mechanism comprises: an in-mold insert and an outer sleeve; the outer sleeve is installed on the in-mold insert, and a driven gear is also provided on the outer sleeve, and the outer sleeve is meshed with the transmission gear through the driven gear thereon, and a threaded structure is also provided on the upper end of the outer sleeve; when the screw moves, it drives the outer sleeve to rotate through the meshing of the transmission gear and the driven gear, and the outer sleeve demoulds the threaded cover through the threaded structure thereon.

[0019] like Figure 1 , 2 As shown, the rotary demoulding device is described in detail below in conjunction with a specific embodiment. The rotary demoulding device of this embodiment includes: a rotating mechanism 10 and at least one group of demoulding mechanisms 20. Among them, when the demoulding mechanisms 20 are set in multiple groups, they can be used for film stripping of multi-cavity molds. In one embodiment, the demoulding mechanisms 20 are four groups. At this time, the four groups of demoulding mechanisms 20 are arranged at intervals around the screw in the circumferential direction.

[0020] The rotating mechanism 10 is used as a power source to drive the demoulding mechanism 20 to perform a demoulding action. Specifically, the rotating mechanism 10 includes: a screw 11 and a transmission gear 12. The screw 11 is fixedly connected to the mold, so that the screw 11 can be linked with it when the mold is opened. The transmission gear 12 is mounted on the screw 11 and can rotate with the axial movement of the screw 11.

[0021] In one embodiment, the rotating mechanism 10 further includes a thread sleeve 13. At this time, the transmission gear 12 is sleeved on the screw 11 through the thread sleeve 13. Accordingly, a thread structure matching the screw 11 is provided on the inner side of the thread sleeve 13. In this way, when the screw 11 is linked with the mold opening, it drives the thread sleeve 13 to rotate through the thread structure, and the thread sleeve 13 further drives the transmission gear 12 connected thereto to rotate.

[0022] In order to maintain the stability of the movement of the screw rod 11, the rotating mechanism 10 further includes a first bearing 14 and a second bearing 15. At this time, the first bearing 14 and the second bearing 15 are sleeved on the screw rod 11 and are located on both sides of the wire sleeve 13. The first bearing 14 and the second bearing 15 radially limit the screw rod 11 to prevent the screw rod 11 from shaking.

[0023] In addition, in order to axially limit the bearing, the rotating mechanism 10 further includes a bearing positioning sleeve 16. At this time, the bearing positioning sleeve 16 is sleeved on the screw 11 and abuts against the second bearing 15. The first bearing 14 and the second bearing 15 are coaxially arranged with the bearing positioning sleeve 16.

[0024] The demoulding mechanism 20 is driven by the rotating mechanism 10 to perform a demoulding action to remove the threaded cover 100 on the outer sleeve thread structure. In this way, the pollution problem caused by the oil cylinder core pulling or hydraulic motor demoulding in the prior art is overcome. Specifically, the demoulding mechanism 20 includes: an in-mold insert 21 and an outer sleeve 22.

[0025] The outer sleeve 22 is mounted on the in-mold insert 21, and a driven gear 23 is also provided on the outer sleeve 22. The outer sleeve 22 is meshed with the transmission gear 12 through the driven gear 23 thereon, and a threaded structure 24 is also provided on the upper end of the outer sleeve 22. Thus, when the screw 11 moves, the outer sleeve 22 is driven to rotate through the meshing of the transmission gear 12 and the driven gear 23, and the outer sleeve 22 removes the threaded cap 100 through the threaded structure 24 thereon. That is, since the injection-molded threaded cap 100 remains fixed, the outer sleeve 22 can be removed from the threaded cap 100 as the mold is separated when rotating.

[0026] In addition, in order to maintain the stability of the movement of the outer sleeve 22, the demoulding mechanism 20 further includes a first guide sleeve 25 and a second guide sleeve 26. At this time, the first guide sleeve 25 and the second guide sleeve 26 are sleeved on the outer sleeve 22 and located on both sides of the driven gear 23.

[0027] In summary, the rotary demoulding device of the utility model has a rotary mechanism, the screw of which can be linked with the mold opening, and then drive the demoulding mechanism to perform demoulding action through the transmission gear to remove the threaded cover on the outer sleeve thread structure. In this way, the pollution problem caused by the oil cylinder core pulling or hydraulic motor demoulding in the prior art is overcome.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
