In general, the injection molded ball valve 10 requires an injection runner on a mold to supply hot melt plastic material to the mold, so that the injection molded product includes an injection molding bracket 80 that is not part of the final product of the ball valve 10, in addition to the ball valve body 12, as shown in fig. 7. The injection molded part requires further cutting of the injection molded bracket 80 before it becomes the final ball valve 10 for use. The ball valve torsion detecting apparatus of the present invention can be applied to the injection molded product in which the injection mold bracket 80 has not been cut and separated from the ball valve body 12 (see fig. 7), and can also be applied to the ball valve 10 in which the injection mold bracket 80 has been cut and separated from the ball valve body 12 (see fig. 5).
For further understanding of the structural features, operational technical means, and expected effects of the present invention, the following description of the usage of the present invention with the injection-molded article of fig. 7 in conjunction with the usage of fig. 8 is believed to provide a more thorough and specific understanding of the present invention:
as shown in fig. 7, in the present embodiment, the injection molded product includes one injection molding bracket 80 and two ball valves 10 as an example, and each of the ball valves 10 includes one ball valve body 12 and one center post 14. In this embodiment, the injection molded bracket 80 has a central main bracket 81, and the central main bracket 81 is located between the ball valve bodies 12 and has a cylindrical shape at the outer side thereof.
As shown in fig. 8, when the ball valve 10 is detected: firstly, the injection molded product is placed on the bearing unit 20, so that the inner side of the lower section 124 of the ball valve body 12 abuts against the outer side of the sleeve 23, the end of the lower section 124 of the ball valve body 12 abuts against the abutting surface 211 on the base 21, and the lower section 124 of the ball valve body 12 is stably placed on the bearing unit 20; the clamping pieces 221 of the fastening clip 22 move closer to each other to clamp the central main supporter 81 between the ball valve bodies 12.
Preferably, as shown in fig. 2, the clamping pieces 221 each have a clamping surface 2221 formed on the inner side thereof, and the clamping surfaces 2221 are at least partially matched with the central main support 81 in shape. In this embodiment, the central main support 81 is cylindrical, so the clamping surface 2221 is an arc surface, the curvature of which matches with at least part of the outer curvature of the central main support 81, so that the fastening clip 22 fits the outer shape of the central main support 81, and clamps the central main support 81 from both sides in a face-to-face manner, thereby preventing the clamping surface 2221 and the central main support 81 from loose due to point-to-point contact when clamping because of non-matching shapes.
Then, the bearing unit 20 moves closer to the torsion unit 30; when the sensing unit 50 senses and confirms that the injection molded product on the carrying unit 20 reaches the predetermined detection position, the pressing disk 41 of the pressing unit 40 moves to above the ball valve body 12 through the rotating arm 42, and presses and fixes the ball valve body 12 on the carrying unit 20 from above; then, the torsion unit 30 moves toward the carrying unit 20, so that the recess 311 of the torsion unit 30 is engaged with the force-receiving portion 143 of the central pillar 14; the rotation shaft 32 of the torsion unit 30 rotates to drive the recess 311 to rotate and rotate the center post 14 sleeved in the recess 311, so as to confirm that the center post 14 is movable in the ball valve body 12 and is not adhered to the ball valve body 12.
Finally, the torsion unit 30 is far away from the carrying unit 20; the pressing disk 41 of the pressing unit 40 is moved away from the ball valve body 12 in the vertical direction; the clamping pieces 221 of the fastening clips 22 of the carrying unit 20 are moved away from each other to release the lower end of the central main bracket 81.

In addition, the arrangement of the bearing unit 20 also avoids the necessity of holding the ball valve body 12 during the torsion detection, and avoids the deformation of the ball valve body 12 due to the torsion detection.
Secondly, by the arrangement of the torsion unit 30, it can be quickly and easily confirmed whether the central pillar 14 in the injection molded ball valve 10 is movable. Even if the center post 14 and the ball valve body 12 in the ball valve 10 are not movable due to heat adhesion, the present invention can release adhesion between the center post 14 and the ball valve body 12 through the torsion of the torsion unit 30, so that the center post 14 can be movable.
Thirdly, the pressing unit 40 is matched with the base 21 and the sleeve 23 of the bearing unit 20, so that the ball valve body 12 is fixed in the vertical direction and the horizontal direction, therefore, when the twisting motion of the twisting unit 30 is performed, the ball valve body 12 does not move on the bearing unit 20, and sufficient supporting force is provided to resist the twisting of the twisting unit 30.
The sensing unit 50 is provided so that the torsion unit 30 can perform torsion detection at an accurate time. Thereby, the torsion unit 30 can be prevented from shearing when the bearing unit 20 does not reach the predetermined detection position yet.
