Abstract
The invention discloses an internal thread detachment mechanism, which includes a screw rod, a nut gear, a third gear, a gear shaft and a copper sheath. One end of the screw rod is fixed on the upper die of a mold. The nut gear is sleeved on a screw rod external side through thread engagement, and the bearing of the nut gear is in fixed connection with the lower die of the mold. The third gear is fixedly sleeved on a gear shaft external side, and the external side of the third gear is in connection with the external side of the nut gear through thread engagement. The external side at one end of the gear shaft is engaged on the internal side of the copper sheath through threads, and the copper sheath is fixedly arranged on the lower die of the mold. And the external side at the other end of the gear shaft is sleeved in the product through threads. The internal thread detachment mechanism is not only simple, but also has good controllability, can realize internal thread detachment of a plurality of products at the same time, and is very convenient to use.
Description
Technical field
The present invention relates to a kind of internal threaded mechanisms of taking off.
Background technology
Product in present mould takes off internal threaded mechanisms and generally adopts motor driven gear, because the machine shaft rotation number of turns is uncontrollable, thereby cause product also uncontrollable when taking off internal thread, when the electric machine rotation driven gear rotates, if it is very few to rotate the number of turns, product can't take off internal thread, if the rotation number of turns is too much, can cause again the damage of product screw thread.
Summary of the invention
In order to overcome defects, the invention provides a kind of internal threaded mechanisms of taking off, this takes off internal threaded mechanisms, and not only result is simple, and controllability is good, takes off internal thread when can realize a plurality of product simultaneously, and is very easy to use.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of internal threaded mechanisms of taking off, comprise screw rod, nut gear, the 3rd gear, tooth axle and copper sheathing, described screw rod one end is fixed on upper mould, described nut gear is sheathed on described screw rod lateral surface by screw-threaded engagement, and the bearing of this nut gear and lower mould are connected; Described the 3rd gear fixed cover is located on described tooth axle lateral surface, and the 3rd gear lateral surface be connected the nut gear lateral surface and connect by screw-threaded engagement; On described copper sheathing medial surface, this copper sheathing is fixedly arranged on lower mould described tooth axle one end lateral surface by screw-threaded engagement; Described tooth axle other end lateral surface is located in product by thread bush.During use, because screw rod one end is fixed on front mould, thereby can not rotate.the bearing of nut gear is fixed on rear mold, when upper and lower mould is opened, nut gear and counterdie move downward together, at this nut gear relative bolt rotary when screw rod moves downward, due to the meshing relation between the 3rd gear and nut gear, nut gear drives the 3rd gear and rotates, while tooth axle is followed the 3rd gear and is rotated together, because copper sheathing and counterdie are fixed, therefore the rotation of tooth axle makes its relative copper sheathing motion, because product is located at tooth axle other end lateral surface by thread bush, therefore the motion of the relative copper sheathing of gear finally spins off product from the tooth axle.
As a further improvement on the present invention, also mesh the second gear between described nut gear and the 3rd gear, be connected with a joggle by gear respectively between the lateral surface of this second gear and nut gear and the 3rd gear lateral surface.
As a further improvement on the present invention, several the 3rd gears of engagement on described the second gear lateral surface, described each the 3rd gear centre sets firmly respectively the tooth axle, and on a copper sheathing medial surface, this copper sheathing is fixedly arranged on lower mould an end lateral surface of described each tooth axle by screw-threaded engagement; Described each tooth axle other end lateral surface is located in a product by thread bush.Like this, after the second meshed transmission gear, a plurality of the 3rd gears and product can be set, thereby take off internal thread, raising efficiency greatly when realizing a plurality of product.
As a further improvement on the present invention, the axis of described nut gear, the second gear and the 3rd gear is parallel respectively.
The invention has the beneficial effects as follows: drive product by meshed transmission gear and take off internal thread, not only simple in structure, and also controllability is good, and product stability is high simultaneously, takes off internal thread when can realize a plurality of product again, and efficient promotes greatly, uses also very convenient.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is cross-sectional view of the present invention.
By reference to the accompanying drawings, make the following instructions:
1---screw rod 2---nut gear
3---the 3rd gear 4---second gear
5---tooth axle 6---copper sheathing
21---bearing 7---product
The specific embodiment
A kind of internal threaded mechanisms of taking off, comprise screw rod 1, nut gear 2, the 3rd gear 3, tooth axle 5 and copper sheathing 6, described screw rod one end is fixed on upper mould, and described nut gear is sheathed on described screw rod lateral surface by screw-threaded engagement, and the bearing 21 of this nut gear is connected with lower mould; Described the 3rd gear fixed cover is located on described tooth axle lateral surface, and the 3rd gear lateral surface be connected the nut gear lateral surface and connect by screw-threaded engagement; On described copper sheathing medial surface, this copper sheathing is fixedly arranged on lower mould described tooth axle one end lateral surface by screw-threaded engagement; Described tooth axle other end lateral surface is located in product 7 by thread bush.During use, as shown in Figure 2, because screw rod one end is fixed on front mould, thereby can not rotate.the bearing of nut gear is fixed on rear mold, when upper and lower mould is opened, nut gear and counterdie move downward together, at this nut gear relative bolt rotary when screw rod moves downward, due to the meshing relation between the 3rd gear and nut gear, nut gear drives the 3rd gear and rotates, while tooth axle is followed the 3rd gear and is rotated together, because copper sheathing and counterdie are fixed, therefore the rotation of tooth axle makes its relative copper sheathing motion, because product is located at tooth axle other end lateral surface by thread bush, therefore the motion of the relative copper sheathing of gear finally spins off product from the tooth axle.
Preferably, also mesh the second gear 4 between above-mentioned nut gear and the 3rd gear, be connected with a joggle by gear respectively between the lateral surface of this second gear and nut gear and the 3rd gear lateral surface.
Preferably, several the 3rd gears (not shown in FIG.) of engagement on above-mentioned the second gear lateral surface, described each the 3rd gear centre sets firmly respectively the tooth axle, and on a copper sheathing medial surface, this copper sheathing is fixedly arranged on lower mould an end lateral surface of described each tooth axle by screw-threaded engagement; Described each tooth axle other end lateral surface is located in a product by thread bush.Like this, after the second meshed transmission gear, a plurality of the 3rd gears and product can be set, thereby take off internal thread, raising efficiency greatly when realizing a plurality of product.
Preferably, the axis of above-mentioned nut gear, the second gear and the 3rd gear is parallel respectively.
