Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figure 1-Figure 4 Shown.

[0021] like Figure 1 and Figure 2 As shown, for the overall structure of the utility model, a high-speed three-station vacuum forming machine includes: a self-centering turntable 1 and a driving member 2 located on the top of the turntable 1, the turntable 1 is equidistantly provided with three groups of forming ports 3 and a group of coordinated ports 4 along its side, each of the forming ports 3 is fixed with a clamping member 5 and a mold block 6, the clamping member 5 includes a top block 7, a clamping block 8, an adjusting bolt 9, a first stopper 10 and a second stopper 11, and each of the two ends of the forming port 3 is concave with a connecting groove 13 on the ground, the top block 7 includes two corresponding bolts fixed at each connecting groove 13 The first stop block 10 and the second stop block 11 are respectively fixedly connected to the bottom of the two top blocks 7, and are arranged opposite to each other and have a first step 14 on the opposite side. The clamping block 8 includes two and is respectively located on the first step 14 of the first stop block 10 and the second stop block 11. The two clamping blocks 8 have a second step 15 on the opposite side, which is adjusted by the adjusting bolt 9 on the back side. The two ends of the mold block are mounted on the second step 15. The coordinated port 4 is used to connect the lifting module in the external blister machine, and the driving member 2 is used to servo rotate the turntable 1.

[0022] Furthermore, the driving component 2 includes a servo motor 16, a reduction gear box 17 and a rotating shaft 18. The output end of the servo motor 16 is transmitted and reduced by the reduction gear box 17. The reduction gear box 17 is coaxially fixed to the rotating shaft 18. The end of the rotating shaft 18 exposed from the reduction gear box 17 is coaxially fixed to the center of the turntable 1.

[0023] Furthermore, the bottom surface of the mold block 6 also has a protruding molding block 19. The bottom surface of the turntable 1 is also fixed with a dividing plate 20, which is used to connect to an external blow molding machine. The first stopper 10 and the second stopper 11 are both threadedly engaged with the adjusting bolt 9, and the backs of the two clamping blocks 8 are both connected and fixed to the adjusting bolt 9. The center of the mold block 6 is hollowed out, and corner blocks 21 are fixed with bolts at the four corners of the bottom. The inner surfaces of the corner blocks 21 are rounded, and the mold block 6 is slidably connected to the rounded corners of the corner blocks 21. The guide pins 22 include at least two and are located at the corners of the bottom surface of the mold block 6.

[0024] Through the above structure, when dealing with sample blow molding, the three suction ports 3 on the turntable 1 can correspond to the external blow molding machine for blow molding in sequence, and the mold block 6 is clamped in each station by the clamping member 5. The adjusting bolt 9 can position, adjust and clamp each mold block 6 to ensure the smooth progress of the blow molding process, and the coordination port 4 is used to connect to the external lifting module, which is not further explained in this structure.

[0025] Specifically, for the clamping operation of the clamping member 5, in this embodiment, the top block 7 is first bolted to the connecting groove 13 at the bottom of each station of the turntable, and then the first stopper 10 and the second stopper 11 can provide support for the two clamping blocks 8. Figure 2 It can be seen that both ends of the mold block 6 can be mounted on the two clamping blocks 8, and the clamping blocks 8 can be mounted on the first stopper 10 and the second stopper 11. By adjusting the bolts 9 and the positioning of the external nuts, the distance between the two clamping blocks 8 can be adjusted instantly, indirectly ensuring that the mold block 6 is clamped and fixed by the two clamping blocks 8. Then, during the blow molding process, the external lifting module is coordinated to shift the height, and the blow molding machine can be embedded in the corresponding four corner blocks 21, while pressing the guide pins 22 to limit the position, and then injection and blow molding are convenient and reliable. Figure 3 Figure 4 As shown, the motor of the driving member 2 rotates, and the reducer is used to slow down the rotating shaft 18, so as to realize the continuous 90° rotation of the turntable. The three stations repeat the operation in sequence, which greatly improves the efficiency of blow molding.

[0026] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
