The first push rod 13 on each mounting plate 10 is rotatably connected to the side wall of the mounting plate 10 in a vertical plane through the shaft connecting member 11, and the two second push rods 14 of each mounting plate 10 are rotatably connected to the side wall of the mounting plate 10 in a horizontal plane through the shaft connecting member 11. The mold 7 is placed on the workbench 5. At the center position, a first guide hole 12 is provided on the side wall of the mold 7 and corresponds to the position of the first push rod 13, and a second guide hole 16 is provided on the side wall of the mold 7 and corresponds to the position of the second push rod 14 and tilted forward and backward; the driving assembly includes a motor 6, a pair of threaded rods 4, a pair of fixed plates 1 and a pair of movable plates 9, the motor 6 has two output ends, and is respectively connected to one end of a pair of threaded rods 4, a pair of fixed plates 1 is fixedly arranged on both sides of the bottom surface of the workbench 5, and the other end of the threaded rod 4 is rotatably connected to the side wall of the fixed plate 1, so The movable plate 9 is provided with a threaded hole, and is screwed to the threaded rod 4 through the threaded hole, and the lower end of the vertical plate 3 is fixedly connected to the upper surface of the movable plate 9; a slider 8 is slidingly provided in the sliding mouth 2, and the vertical plate 3 passes through the center position of the slider 8 and is fixedly connected to the slider 8; torsion springs 15 are provided on both sides of the shaft connecting member 11, and the torsion springs 15 can reset the first push rod 13 and the second push rod 14; the inner diameter of the opening of the first guide hole 12 and the second guide hole 16 is greater than or equal to twice the diameter of the first push rod 13 and the second push rod 14.

[0022] The detailed connection means are well known in the art. The following mainly introduces the working principle and process, which are as follows:

[0023] According to the instruction manual Figure 1-5It can be seen that when the present invention is working, the driving assembly at the bottom of the workbench 5 works, driving the vertical plates 3 on its two moving ends to move outward at the same time, leaving enough installation space on the workbench 5, and the slide 2 can limit the vertical plates 3 to a certain extent. The mold 7 to be fixed is placed at the designated position in the center of the workbench 5. Let the driving assembly work again, so that the two moving ends drive a pair of vertical plates 3 to move inward, driving the mounting plate 10 and the first push rod 13 and the second push rod 14 on the mounting plate 10 to move toward the mold 7. Since the side wall of the mold 7 is provided with a first guide hole 12 and a second guide hole 16 corresponding to the first push rod 13 and the second push rod 14, the movement of the mounting plate 10 can enable the first push rod 13 to be inserted into the first guide hole 12, and the second push rod 14 to be inserted into the second guide hole 16. Since the first push rod 13 is connected to the side wall of the mounting plate 10 in a vertical plane through the shaft connection 11, and the opening direction of the first guide hole 12 is inclined downward, the first push rod 13 and the second push rod 14 are connected in a vertical plane. A push rod 13 is ultimately tilted downwardly against the bottom of the first guide hole 12. Since the two second push rods 14 on each mounting plate 10 are rotatably connected to the side walls of the mounting plate 10 in a horizontal plane via the shaft connector 11, and the second guide hole 16 is opened in an inclined direction toward the front and rear of the mold 7, the two second push rods 14 ultimately tilt forward and tilt backward, respectively. Since the first push rods 13 and the second push rods 14 on the mounting plates 10 on both sides of the center of the workbench 5 are symmetrically designed, the drive assembly drives the vertical plate 3 and the mounting plate 10 to move inward, enabling the pair of first push plates and the two pairs of second push rods 14 to clamp and fix the mold 7. Compared to the prior art, the drive assembly in the present invention has only one power source, which can drive the first push rod 13 and the second push rod 14 to act on the first guide hole 12 and the second guide hole 16 of the mold 7, respectively, so that they can squeeze and fix the mold 7 in three directions, which is stable and streamlines the parts on the workbench 5, facilitating repair and maintenance, saving energy, and saving costs. To explain the extrusion fixation of the mold in the three directions of 7x, y, and z, refer to Figure 4 and Figure 5 The force analysis is performed on the left side of the mold 7. F is the total thrust given to the mounting plate 10 by the driving assembly, and is also the total thrust given to the mold 7, which is parallel to the x-axis. The first push rod 13 gives the components of force to the mold 7, respectively, FZ and FX. FZ cooperates downward with the support of the workbench 5 to fix the mold 7 in the z direction. The two second push rods 14 give the components of force to the mold 7, respectively, FY and FX, and FY and FX. FY is balanced with FY to fix the mold 7 in the y direction. Since the first push rod 13 and the second push rod 14 on the mounting plates 10 on both sides of the center of the workbench 5 are symmetrically designed, the force in the x direction of the mold 7 is also balanced, thereby achieving fixation of the mold 7 in the x direction. In summary, the utility model only uses one power source to extrude and fix the mold 7 in the x, y and z directions.

[0024] The drive assembly includes a motor 6, a pair of threaded rods 4, a pair of fixed plates 1, and a pair of movable plates 9. The motor 6 has two output terminals, each connected to one end of the pair of threaded rods 4. The pair of fixed plates 1 are fixedly mounted on both sides of the bottom surface of the workbench 5. The other ends of the threaded rods 4 are rotatably connected to the side walls of the fixed plates 1. The movable plates 9 have threaded holes through which they are screwed to the threaded rods 4. The lower end of the vertical plate 3 is fixedly connected to the upper surface of the movable plates 9. When the motor 6 is working, it drives the two threaded rods 4 to rotate, thereby driving the movable plates 9 to which they are screwed, and further driving the vertical plates 3 and the mounting plate 10 connected to the movable plates 9 to move. This results in strong synchronization and even force on both sides.

[0025] Among them, a slider 8 is slidingly provided in the sliding mouth 2, and the vertical plate 3 passes through the center position of the slider 8 and is fixedly connected to the slider 8. The movement of the vertical plate 3 is limited by the slider 8, which ensures the stability of the movement and also increases the stability of the force applied to the vertical plate 3.

[0026] Among them, torsion springs 15 are provided on both sides of the shaft connecting member 11, which can reset the first push rod 13 and the second push rod 14. The shaft connecting member 11 is an existing technology and can realize the rotation relationship between the first push rod 13 and the second push rod 14 and the side wall of the mounting plate 10.

[0027] Among them, the opening inner diameter of the first guide hole 12 and the second guide hole 16 is greater than or equal to twice the diameter of the first push rod 13 and the second push rod 14. This is to ensure that the first push rod 13 and the second push rod 14 can be accurately inserted into the first guide hole 12 and the second guide hole 16 to ensure smooth work.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
