Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a movable mould hank tooth mechanism, includes module 1, and module 1 includes actuating mechanism 2, follower 3 and correction mechanism 4, and actuating mechanism 2 sets up in module 1's inside, and follower 3 sets up in actuating mechanism 2's one end, and correction mechanism 4 sets up in follower 3's periphery.

The driving mechanism 2 comprises a driving gear 21, a main shaft 22 penetrates through the driving gear 21, a driving gear 23 is installed at one end, away from the driving gear 21, of the main shaft 22, the driven mechanism 3 comprises a driven gear 31, a driven shaft 32 penetrates through the driven gear 31, and the driving gear 23 is meshed with the driven gear 31.

Referring to fig. 2-3, the correcting mechanism 4 includes a first taper bearing 41, a second taper bearing 42, and a deep ball groove bearing 43, the driven shaft 32 jointly penetrates through the first taper bearing 41, the second taper bearing 42, and the deep ball groove bearing 43, the first taper bearing 41 is disposed on a side of one end of the driven shaft 32, the second taper bearing 42 is disposed on a side of a middle portion of the driven shaft 32, the deep ball groove bearing 43 is disposed on a side of one end of the driven shaft 32 away from the first taper bearing 41, a diameter of one end of the driven shaft 32 away from the first taper bearing 41 is set to be smaller than a diameter of the first taper bearing 41, and a mold cavity 5 is disposed at one end of the driven shaft 32 away from the first taper bearing 41.

The working principle is as follows: when the device is started, under the drive of external torque, the driving gear 21 drives the driving gear 23 to rotate through the main shaft 22, the driving gear 23 drives the driven shaft 32 to rotate through the driven gear 31, one end of the driven shaft 32 rotates at high speed in the model cavity 5, after the injection molding material is molded in the mold cavity 5, an inner hole can be directly formed in the molded product, and the inner hole is directly provided with a thread under the rotation of the driven shaft 32, in the process, the first taper bearing 41 is abutted against the bottom end of the driven shaft 32, and the second taper bearing 42 is abutted against the middle part of the driven shaft 32, so that when the driven shaft 32 rotates, the eccentric range is greatly reduced, and the deep ball groove bearing 43 limits the eccentric range of the top end of the driven shaft 32, the eccentric range of the driven shaft 32 is reduced again, and the phenomenon that when the driven shaft 32 rotates at a high speed, the top end of the driven shaft produces overlarge eccentric rotation, so that the accuracy of the formed thread is low is avoided.
