DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings. The described embodiments are only a part of the embodiments, and all other embodiments obtained by those skilled in the art without creative labor on the basis of the embodiments in the present solution shall fall within the protection scope of the present solution.

[0024] As Figures 1 to 4 shown, the present embodiment designs a positioning assembly of an adjustable mold protection switch, which comprises a limiting groove, a movable positioning bead 56 and a compression spring 57.

[0025] The adjustable mold protection switch comprises an installation shell 1 and a threaded adjusting assembly 5; the front end of the installation shell 1 is provided with a magnet block 2, and the rear end is provided with an end plate 12; a slidable installation sleeve 3 is arranged on the installation shell 1, and the installation sleeve 3 is used for installing a detection sensor 4; the threaded adjusting assembly 5 comprises a threaded sleeve, a threaded rod 52 and a handle 54, the threaded sleeve is arranged in the installation shell 1 and fixedly connected with the installation sleeve 3; the threaded rod 52 is threadedly connected with the threaded sleeve, and the rear end of the threaded rod 52 extends out of the installation shell 1 from the center hole of the end plate 12 and is fixedly connected with the handle 54.

[0026] An installation slot 11 is arranged on the installation shell 1, and a part of the installation sleeve 3 extends into the installation shell 1 from the installation slot 11 and is fixedly connected with the threaded sleeve. A bearing 53 is arranged at the center hole of the end plate 12, and the end plate 12 is connected with the threaded rod 52 through the bearing 53. The end plate 12 is a square plate, and screw mounting holes are arranged at four corners of the end plate 12, and the end plate 12 is connected with the installation shell 1 through screws.

[0027] When in use, the adjustable mold protection switch allows the magnet 2 to magnetically attach to the moving platen of the mold, thereby mounting the mounting shell 11 onto the mold. Rotating the threaded rod 52 controls the back-and-forth movement of components such as the threaded sleeve and mounting sleeve 3. The detection sensor 4 mounted on the mounting sleeve 3 also moves back and forth accordingly. The position of the detection sensor 4 should ensure that it is triggered and sends a detection signal when the mold is closed.

[0028] The limiting groove is provided on the end plate 12, and the movable positioning bead 56 is movably provided on the handle 54. The compression spring 57 abuts against the movable positioning bead 56 and is used to push the movable positioning bead 56 into the limiting groove. When the movable positioning bead 56 is inserted into the limiting groove, the external force needs to overcome the elastic force of the spring and squeeze the movable positioning bead 56 out of the limiting groove.

[0029] The limiting grooves are multiple and arranged around the central hole of the end plate 12; the position of each limiting groove can limit the threaded rod 52.

[0030] The limiting groove and the movable positioning bead 56 can be matched in the following two ways:

[0031] In the first type of combination, such as Figure 3 As shown in (a), the limiting groove is a second limiting groove 15, which is a groove provided on the rear end face of the end plate 12. Figure 3 As shown in (b), a mounting hole is provided on the front end face of the handle 54, the compression spring 57 is installed in the mounting hole, and the movable positioning bead 56 is located at the opening of the mounting hole; the axial direction of the mounting hole is parallel to the axial direction of the threaded rod 52. The compression spring 57 presses the movable positioning bead 56 forward, thereby pressing the movable positioning bead 56 into a second limiting groove 15.

[0032] In the second type of combination, such as Figure 4 As shown in (a), an annular protrusion 13 is provided on the rear end face of the end plate 12, and the limiting groove is a first limiting groove 14, which is a groove provided on the inner wall of the annular protrusion 13. Figure 4 As shown in (b), a boss 55 is provided at the center of the front part of the handle 54, and the boss 55 is inserted into the annular protrusion 13; a mounting hole is provided on the outer wall of the boss 55, the compression spring 57 is installed in the mounting hole, and the movable positioning bead 56 is provided at the opening of the mounting hole; the axial direction of the mounting hole is perpendicular to the axial direction of the threaded rod 52. The compression spring 57 presses the movable positioning bead 56 radially outward, thereby pressing the movable positioning bead 56 into a second limiting groove 15.

[0033] The positioning assembly in the embodiment can position the position of the threaded rod 52 after rotation, thereby preventing the threaded rod 52 from being misrotated due to mold vibration, slight rotation of the threaded rod 52 and the like, and effectively ensuring the position accuracy and stability of the detection sensor 4 after calibration.

[0034] The above embodiments are merely examples for clearly illustrating the present application and are not intended to limit the embodiments; all the embodiments are not required to be enumerated here. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
