At present, the mold has gradually become the core of the manufacturing industry in the manufacturing industry. Among some components that require threads as a connection and matching structure, some components have complex exteriors or parts formed of plastics, which cannot be realized in ordinary processing, so they need to be processed through molds. Mold opening is realized, and there are many ways to separate the product from the mold from the threaded mold, including manual operation, using a rack to remove the thread structure, etc., but these methods for removing the thread are relatively simple, and the work efficiency is not high. Some use structures such as motor drive to pump two products at a time, but the efficiency has not been greatly improved, and the control of the motor is not perfect. When the motor drive is not needed, the motor still works, resulting in waste of resources.

Preferably, the travel switch includes an up travel switch and a down travel switch, and the up travel switch is located above the down travel switch.

Preferably, the lower part of the dental inlay is provided with a travel switch sensing block, and the travel switch sensing block is located between the upper travel switch and the lower travel switch.

The beneficial effect of the utility model is that: the driving gear on the rotating shaft is driven by the motor to rotate, thereby driving the driven gear to rotate, so that the tooth insert moves downward to realize the thread removal process, and multiple thread removal actions can be completed at one time. When the bottom of the insert touches the travel switch, the relay is de-energized and the mechanism stops operating, maximizing resource utilization.

【Detailed ways】

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Fig. 1 and Fig. 2, a high-efficiency dethreading mechanism of the present invention includes a motor 1 and a rotating shaft 2, and a sprocket 3 is arranged on the motor 1 and the rotating shaft 2, and a chain 4 is passed between the sprocket wheels 3. connection, a driving gear 5 is arranged on the rotating shaft 2, and the driving gear 5 is fixed on the rotating shaft 2 through a key connection, and four driven gears 6 are respectively arranged outside the driving gear 5, and the driven gear 6 and the driving The gears 5 are meshed, and each driven gear 6 is provided with a tooth insert 7, and an upper mold plate 8, a middle mold plate 9 and a lower mold plate 10 are respectively provided outside the tooth insert 7, and on the upper mold plate 8 A needle roller bearing 11 is provided. The needle roller bearing 11 has a large bearing capacity and does not need to be axially positioned during installation. The inner ring of the needle roller bearing 11 is connected to the outside of the tooth insert 7. Deep groove ball bearings 12 are provided on the mold plate 10, and the inner ring of the deep groove ball bearings 12 is connected to the outside of the dental insert 7. In order to maximize resource utilization, a stroke is provided below the dental insert 7. switch, the travel switch is connected with the relay that controls the movement of the motor, the travel switch includes an upper travel switch 13 and a lower travel switch 14, the upper travel switch 13 is located above the lower travel switch 14, at the bottom of the dental insert 7 A travel switch sensing block 15 is also provided, and the travel switch sensing block 15 is located between the upper travel switch 13 and the lower travel switch 14 .

The working process of the present utility model is as follows: the product on the dental insert 7 is fixed with a clamp, and then the motor 1 is started, and the drive shaft of the motor 1 drives the sprocket 3, and the sprocket 3 drives the chain wheel on the rotating shaft 2 through the chain 4. The driving gear 5 rotates, and the driving gear 5 drives the surrounding four driven gears 6 to rotate, thereby causing a plurality of dental inserts 7 to rotate and move downward, so that the product is separated from the dental inserts 7. When the dental inserts 7 When the lower travel switch sensor block touches the lower travel switch 14, the relay that controls the rotation of the motor 1 will be powered off, and then the motor 1 will stop working.
