[0020] Please see Figures 1-4 A blow molding die clamping device includes a first support shell 1 and a second support shell 2. Clamping mechanisms 3 are mounted on the surfaces of both the first and second support shells 1 and 2. Each clamping mechanism 3 includes a first threaded rod 30, which passes through and is movably connected to the first support shell 1. First moving blocks 31 are threadedly fitted onto the upper and lower sides of the surface of the first threaded rod 30. A U-shaped plate 32 is fixedly connected to one side of the first moving block 31. A second threaded rod 33 is movably connected through the surface of the U-shaped plate 32. Second moving blocks 33 are threadedly fitted onto the left and right sides of the surface of the second threaded rod 33. Block 34, a clamping plate 35 is fixedly connected to one side of the second moving block 34, and the mold body 36 is clamped between the two clamping plates 35. By setting the first threaded rod 30, the first moving block 31, the U-shaped plate 32, the second threaded rod 33, the second moving block 34 and the clamping plate 35, the upper and lower U-shaped plates 32 can be moved closer or further away from each other, which is convenient for clamping and fixing molds of different lengths. The two clamping plates 35 can be moved closer or further away from each other, which is convenient for clamping and fixing molds of different widths. Thus, it can easily adapt to molds of different widths and lengths, and greatly improve the versatility and applicability of the device.

[0021] Please see Figures 3-4 The surfaces of the first support shell 1 and the second support shell 2 are both provided with a first vertical hole 37. The first moving block 31 passes through the first vertical hole 37 and is movably connected to the first vertical hole 37. The threads on the upper and lower sides of the surface of the first threaded rod 30 are turned in opposite directions. A first knob is fixedly connected to the top of the first threaded rod 30. The first vertical hole 37 provides precise guidance and limit for the movement of the first moving block 31, ensuring that the first moving block 31 can only move in a straight line up and down along the first vertical hole 37, thus ensuring the stability and accuracy of the movement of the upper and lower U-shaped plates 32. The setting of the first knob makes it convenient for the operator to manually rotate the first threaded rod 30, making the operation more convenient and labor-saving.

[0022] Please see Figure 4The surfaces of the first support shell 1 and the second support shell 2 are both provided with second vertical holes 38. A vertical rod 39 is fixedly connected to the inner cavity of the first support shell 1. Guide blocks 310 are movably fitted on the upper and lower sides of the surface of the vertical rod 39. One side of the guide block 310 passes through the second vertical hole 38 and is fixedly connected to the U-shaped plate 32. The cooperation of the second vertical hole 38, the guide block 310, and the vertical rod 39 further enhances the stability of the movement of the U-shaped plate 32. The guide block 310 slides on the vertical rod 39, providing support and guidance for the up and down movement of the U-shaped plate 32, preventing the U-shaped plate 32 from shaking or deviating during movement, sharing part of the force borne by the first moving block 31, and extending the service life of the first moving block 31.

[0023] Please see Figure 3 The surface of the U-shaped plate 32 has a horizontal hole 311. The second moving block 34 passes through the horizontal hole 311 and is movably connected to the horizontal hole 311. The threads on both sides of the surface of the second threaded rod 33 are in opposite directions. One end of the second threaded rod 33 is fixedly connected to a second knob. The horizontal hole 311 provides guidance and space for the left and right movement of the second moving block 34, ensuring that the second moving block 34 can move smoothly in a straight line along the horizontal hole 311, so that the two clamping plates 35 can accurately approach or move away from the mold, achieving precise clamping of molds of different widths. The second knob makes it convenient for the operator to manually rotate the second threaded rod 33, making the operation simple and quick.

[0024] Please see Figures 1-2 A fixing plate 4 is fixedly connected to the surface of the first support shell 1 and the second support shell 2. A cylinder 5 is connected through the surface of the rear fixing plate 4. The front side of the cylinder 5 is fixedly connected to the front fixing plate 4. The setting of the cylinder 5 realizes the automatic adjustment of the distance between the first support shell 1 and the second support shell 2, which facilitates the closing and opening between the two mold bodies 36. After the plastic bottle is formed inside the mold body 36, it is convenient to unload the plastic bottle.

[0025] Please see Figures 1-2 A guide tube 6 is fixedly connected to the surface of the rear fixing plate 4, and a guide rod 7 is connected through the surface of the guide tube 6. The front side of the guide rod 7 is fixedly connected to the front fixing plate 4. The cooperation of the guide tube 6 and the guide rod 7 provides precise guidance and support for the movement of the first support shell 1 and the second support shell 2. The guide rod 7 slides in the guide tube 6 to ensure that the front fixing plate 4 can only move in a straight line along the axis of the guide rod 7, preventing it from deviating or shaking during the movement.

[0026] In use, the mold body 36 is placed between two vertical U-shaped plates 32. The first threaded rod 30 is rotated to drive the first moving block 31 to move. The first moving block 31 drives the U-shaped plates 32 to move. The two U-shaped plates 32 move closer to the mold and clamp the mold. The second threaded rod 33 is rotated to drive the second moving block 34 to move. The second moving block 34 drives the clamping plate 35 to move. The two clamping plates 35 move closer to the mold and clamp the mold. The blow molding machine is inserted from the top of the mold body 36 to blow mold the material. By controlling the cylinder 5 to extend, the front fixed plate 4 is moved, so that the second support shell 2 moves away from the first support shell 1, and the front and rear mold bodies 36 are separated, which facilitates the unloading of the finished product.

[0027] In summary, this blow molding machine mold clamping device, by setting up a first threaded rod 30, a first moving block 31, a U-shaped plate 32, a second threaded rod 33, a second moving block 34, and a clamping plate 35, solves the problems that the clamping device is not convenient to adjust the clamping structure in a convenient and flexible manner, is not convenient to clamp molds of different widths and lengths, and is difficult to adapt to molds of different widths and lengths.
