DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 3 As shown, a positioning fixture for mold processing includes a workbench 1, a rectangular groove 3 is provided at the upper end of the workbench 1, a positioning assembly 7 is arranged above the workbench 1, and the positioning assembly 7 includes a movable plate 8, a semicircular groove 14 is provided at the upper end of the movable plate 8, a No. 1 semicircular plate 9 is provided on one side of the semicircular groove 14, a clamping ring 10 is fixedly installed on the outside of the No. 1 semicircular plate 9, a clamping groove 15 is provided on the inner wall of one side of the semicircular groove 14, two No. 2 semicircular plates 11 are provided on one side of the No. 1 semicircular plate 9, two No. 3 semicircular plates 12 are provided on one side of the No. 2 semicircular plate 11, and two rubber columns 1 are fixedly installed on one side of the No. 3 semicircular plate 12 3. First, place the mold to be processed on the workbench 1 and between the movable plate 8 and the fixed plate 6. Through the positioning component 7, start the rotating motor 5 on one side of the workbench 1. The rotating motor 5 drives the screw 4 to rotate, so that the slider 16 drives the movable plate 8 to move toward the fixed plate 6. At this time, the rubber column 13 on the side of the third semicircular plate 12 first contacts the mold. When the mold is a rectangular body, one side of the first semicircular plate 9, the second semicircular plate 11 and the third semicircular plate 12 are evenly stressed, so that the first semicircular plate 9, the second semicircular plate 11 and the third semicircular plate 12 will not rotate, and the mold is positively positioned and clamped.

[0021] In this embodiment, a slider 16 is fixedly mounted on the lower end of the movable plate 8 , and the slider 16 is located inside the rectangular groove 3 .

[0022] In this embodiment, a threaded through hole 17 is formed on one side of the slider 16 , and a rotating motor 5 is fixedly mounted on one side of the workbench 1 .

[0023] In this embodiment, one end of the output shaft of the rotating motor 5 passes through the interior of the rectangular groove 3, and a screw rod 4 is fixedly installed on one end of the output shaft. The screw rod 4 is threadedly connected to the threaded through hole 17, so that the slider 16 moves while the screw rod 4 rotates.

[0024] In this embodiment, a fixed plate 6 is fixedly installed on the upper end of the workbench 1, and the fixed plate 6 and the movable plate 8 are symmetrically arranged, and a semicircular plate 9 is also arranged on one side of the fixed plate 6, and a supporting leg 2 is fixedly installed on the lower end of the workbench 1.

[0025] In this embodiment, the clamping ring 10 is movably engaged with the clamping groove 15 , and a semicircular groove 14 is formed on one side of the first semicircular plate 9 and the second semicircular plate 11 .

[0026] In this embodiment, the connection method of the No. 1 semicircular plate 9 and the No. 2 semicircular plate 11 is consistent with the connection method of the movable plate 8 and the No. 1 semicircular plate 9, and the connection method of the No. 2 semicircular plate 11 and the No. 3 semicircular plate 12 is also consistent with the connection method of the movable plate 8 and the No. 1 semicircular plate 9. When the mold to be positioned is a special-shaped part, when the two rubber columns 13 are subjected to uneven forces, the No. 3 semicircular plate 12 will rotate, and accordingly, the No. 2 semicircular plate 11 and the No. 1 semicircular plate 9 will rotate accordingly, so that the rubber column 13 is always in contact with the special-shaped mold, and the movable plate 8 moves toward the fixed plate 6 to effectively clamp the special-shaped mold.

[0027] The implementation principle of the positioning fixture for mold processing in the embodiment of the present application is as follows: first, the mold to be processed is placed on the workbench 1 and located between the movable plate 8 and the fixed plate 6. The rotating motor 5 on one side of the workbench 1 is started through the positioning assembly 7, and the rotating motor 5 drives the screw 4 to rotate, so that the slider 16 drives the movable plate 8 to move toward the fixed plate 6. At this time, the rubber column 13 on one side of the third semicircular plate 12 first contacts the mold. When the mold is a rectangular body, the first semicircular plate 9, the second semicircular plate 11 and the third semicircular plate 12 are in contact with the mold. One side of the semicircular plate 12 is subjected to uniform force, so that the No. 1 semicircular plate 9, the No. 2 semicircular plate 11 and the No. 3 semicircular plate 12 will not rotate, and the mold is positively positioned and clamped. When the mold to be positioned is a special-shaped part, the two rubber columns 13 are subjected to uneven force, and the No. 3 semicircular plate 12 will rotate. Correspondingly, the No. 2 semicircular plate 11 and the No. 1 semicircular plate 9 will rotate in the opposite direction, so that the rubber column 13 is always in contact with the special-shaped mold, and the movable plate 8 moves toward the fixed plate 6 to effectively clamp the special-shaped mold.
