[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 A positioning and clamping fixture for processing mold inserts includes: a work box 1, a support plate 2 that can be slidably provided on both sides of the top of the work box 1, a rotating rod 3 that is rotatably connected to the opposite side of the two support plates 2, an L-shaped plate 4 that is fixed to the opposite end of the two rotating rods 3, and a pressure plate 5 that can be slidably provided on one side of the two L-shaped plates 4.

[0025] Two clamping components 6 are respectively disposed on one side of the two L-shaped plates 4. The two clamping components 6 are respectively connected to the two pressure plates 5 and are used to drive the movement of the pressure plates 5.

[0026] The flipping component 7 is located on one side of the support plate 2. The flipping component 7 is connected to the rotating rod 3 and is used to drive the rotation of the rotating rod 3.

[0027] In this embodiment, when clamping the insert, both ends of the insert are placed on two L-shaped plates 4 respectively. Then, under the movement of the clamping component 6, the pressure plate 5 moves downward, which can clamp and fix the insert, making it convenient for processing. When different surfaces of the insert need to be processed, under the movement of the flipping component 7, the rotating rod 3 is driven to rotate. The rotating rod 3 drives the L-shaped plate 4 to rotate, thereby driving the insert to rotate, which can flip the insert, making it convenient for processing different surfaces of the insert, facilitating the rapid processing of the insert and improving the processing efficiency of the insert.

[0028] In a further embodiment, such as Figure 3 As shown, the clamping assembly 6 includes a first slider 61 fixedly disposed on one side of the pressure plate 5, a first groove 62 for sliding the first slider 61 is provided on one side of the L-shaped plate 4, and a screw 63 that rotates with the first slider 61 is threadedly connected to the top of the L-shaped plate 4, and a handle 64 is fixed to the top of the screw 63.

[0029] In this embodiment, after the insert is placed on the L-shaped plate 4, the handle 64 is manually rotated. The handle 64 drives the screw 63 to feed, and the screw 63 drives the first slider 61 to move downward. The first slider 61 drives the pressure plate 5 to move downward, thus pressing and fixing the insert.

[0030] In a further embodiment, such as Figure 2 As shown, the flipping assembly 7 includes a motor base 71 fixedly mounted on one side of the support plate 2. A first drive motor 72 is fixed to the top of the motor base 71. A drive wheel 73 is fixed to the output shaft of the first drive motor 72. A driven wheel 74 that meshes with the drive wheel 73 is fixed to one end of the rotating rod 3.

[0031] In this embodiment, when different surfaces of the insert need to be processed, the first drive motor 72 drives the drive wheel 73 to rotate, the drive wheel 73 drives the driven wheel 74 to rotate, the driven wheel 74 drives the rotating rod 3 to rotate, the rotating rod 3 drives the L-shaped plate 4 to rotate, thereby driving the insert to rotate and perform flipping processing on the insert.

[0032] In a further embodiment, such as Figure 4 As shown, the bottom ends of the two support plates 2 are fixed with second sliders 8. The top of the work box 1 is provided with a second slide groove 9 for the second sliders 8 to slide. The inside of the work box 1 is provided with a horizontal plate 10 that can be raised and lowered. The top of the horizontal plate 10 is hinged with two pull rods 11 that are hinged to the second sliders 8. The horizontal plate 10 is connected to the inner wall of the work box 1 through a sliding assembly 12. The work box 1 is provided with a lifting assembly 13 that drives the horizontal plate 10 to move.

[0033] In this embodiment, when clamping and fixing the insert, the length of the insert is first determined. Then, under the movement of the lifting assembly 13, the horizontal plate 10 is driven to move up and down. The horizontal plate 10 pulls the movement of the two pull rods 11, which in turn pulls the two second sliders 8 to move in the opposite direction. The two second sliders 8 drive the two support plates 2 to move in the opposite direction, thereby driving the two L-shaped plates 4 to move in the opposite direction. The distance between the two L-shaped plates 4 is adjusted so that the spacing is adapted to the length of the insert, making it convenient to place the insert on the L-shaped plates 4. This facilitates the clamping and fixing of inserts of different sizes and improves the clamping efficiency of the insert.

[0034] In a further embodiment, such as Figure 4 As shown, the sliding assembly 12 includes a third slider 121 fixedly disposed at both ends of the horizontal plate 10, and a third groove 122 for sliding the third slider 121 is provided on both sides of the inner wall of the work box 1.

[0035] In this embodiment, when the horizontal plate 10 moves up and down, it drives the third slider 121 to slide in the third slide groove 122. In this way, with the cooperation of the third slider 121 and the third slide groove 122, it is convenient to provide auxiliary support for the horizontal plate 10 and maintain the stability of the horizontal plate 10's movement.

[0036] In a further embodiment, such as Figure 4 As shown, the lifting assembly 13 includes two connecting rods 131 hinged to the bottom of the horizontal plate 10. The bottom ends of the two connecting rods 131 are each hinged to a fourth slider 132. The bottom end of the inner wall of the working box 1 is provided with a fourth slide groove 133 for the fourth slider 132 to slide. A bidirectional lead screw 134 that is threadedly connected to the fourth slider 132 is rotatably connected in the fourth slide groove 133. A second drive motor 135 that is fixed to the bidirectional lead screw 134 is fixed on one side of the working box 1.

[0037] In this embodiment, the second drive motor 135 drives the rotation of the bidirectional lead screw 134, which in turn drives the two fourth sliders 132 to move in opposite directions. The two fourth sliders 132 pull the movement of the two connecting rods 131, thereby driving the horizontal plate 10 to move up and down.

[0038] The working principle of the positioning and clamping fixture for mold insert processing provided by this utility model is as follows: When clamping and fixing the insert, the length of the insert is first determined. Under the movement of the second drive motor 135, the bidirectional lead screw 134 is driven to rotate. The bidirectional lead screw 134 drives the two fourth sliders 132 to move in opposite directions. The two fourth sliders 132 pull the movement of the two connecting rods 131, thereby driving the horizontal plate 10 to move up and down. The horizontal plate 10 pulls the movement of the two pull rods 11, which in turn pull the two second sliders 8 to move in opposite directions. The two second sliders 8 drive the two support plates 2 to move in opposite directions, thereby driving the two L-shaped plates 4 to move in opposite directions. The distance between the two L-shaped plates 4 is adjusted so that the spacing is adapted to the length of the insert, making it convenient to place the insert in the L-shaped plate. The insert is placed on plate 4, which facilitates the clamping and fixing of inserts of different sizes, improving the clamping efficiency of the inserts. After the insert is placed on L-shaped plate 4, the handle 64 is manually turned. The handle 64 drives the screw 63 to feed, and the screw 63 drives the first slider 61 to move downward. The first slider 61 drives the pressure plate 5 to move downward, which can clamp and fix the insert, and the insert can be processed. When it is necessary to process different surfaces of the insert, the first drive motor 72 drives the drive wheel 73 to rotate. The drive wheel 73 drives the driven wheel 74 to rotate, and the driven wheel 74 drives the rotating rod 3 to rotate. The rotating rod 3 drives the L-shaped plate 4 to rotate, thereby driving the insert to rotate and flip the insert for processing, which facilitates the rapid processing of the insert and improves the processing efficiency of the insert.
