Description

Technical Field

[0001] This utility model belongs to the field of blow molding machine technology, and relates to a combined linkage mechanism for the linkage between the motorized side mold and the bottom mold of high-speed blow molding. Background Technology

[0002] Currently, the main process for processing plastic bottles is through blow molding machines. The blow molding die is an important component of the blow molding machine, enabling the production of plastic bottles of different shapes.

[0003] A search revealed that CN215970045U discloses a high-speed rotary blow molding machine, comprising a lifting cylinder with a lifting piston sealed to the cylinder wall, and a lifting piston rod connected to one side of the lifting piston; a lifting rod including an upper rod body and a lower rod body connected to each other, the upper end of the upper rod body being fixedly connected to the lifting piston rod via a coupling, the lower rod body being made of engineering plastic, and the lower end face of the lower rod body being flat, with a rounded transition between the flat surface and the cylindrical surface of the lower rod body, so that when the lifting rod stretches the preform, the force applied to the preform at various positions at the bottom of the lifting rod is evenly distributed, eliminating the need to replace the lifting rod in real time according to the size of the preform, thus improving the working efficiency of the rotary blow molding machine.

[0004] The aforementioned high-speed blow molding machine mainly addresses the issue of tension rod replacement. However, during use, we discovered that the blow molding machine lacks a linkage structure between the moving side mold and the bottom mold. This results in poor stability during the separation or closing of the moving side mold and the bottom mold, increasing the impact between them. To address this, we designed a combined linkage mechanism that links the moving side mold and the bottom mold in a high-speed blow molding machine. Summary of the Invention

[0005] The purpose of this invention is to provide a combined linkage mechanism for the linkage between the motorized side mold and the bottom mold in high-speed blow molding, so as to solve the problems mentioned in the background art.

[0010] In the above-mentioned combined linkage mechanism of high-speed blow molding motorized side mold and bottom mold linkage, fixed seats are fixed at the four corners of the first fixed plate and the second fixed plate, and the fixed seats are threadedly connected to the ends of the corresponding slide rods.

[0011] In the aforementioned combined linkage mechanism for high-speed blow molding, the size and dimensions of the first fixed plate, the second fixed plate, and the movable slider are all the same.

[0012] Compared with the prior art, the advantages of the combined linkage mechanism of the high-speed blow molding machine's moving side mold and bottom mold are as follows: the linkage mechanism between the moving side mold and the bottom mold is simple, the dynamic load is small, it can effectively reduce the vibration and impact of the mechanism, reduce the wear of parts, can accurately control the movement of the moving side mold, enhance the smoothness and reliability of the blow molding machine, and improve the high-speed performance of the whole machine.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-4 As shown, the combined linkage mechanism for the high-speed blow molding machine's moving side mold and bottom mold includes a first fixed plate 1 and a second fixed plate 2. Four sliding rods 3 are fixedly installed at the four corners between the first fixed plate 1 and the second fixed plate 2. The four sliding rods 3 are slidably connected by a movable slider 4. A moving side mold 5 is provided on the side of the movable slider 4. A bottom mold 11 adapted to the moving side mold 5 is provided on the side of the second fixed plate 2. Vertical rods 6 are fixedly installed on the top of the sides of both the movable slider 4 and the second fixed plate 2. A linkage mechanism is provided between the two vertical rods 6.

[0020] Specifically, a linkage mechanism is provided between the moving side mold 5 and the bottom mold 11 in the blow molding machine. The mechanism is simple, has a small dynamic load, can effectively reduce the vibration and impact of the mechanism, reduce the wear of parts, can accurately control the movement of the moving side mold 5, enhance the smoothness and reliability of the blow molding machine, and improve the high-speed performance of the whole machine.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a combined linkage mechanism for linking the motorized side mold and the bottom mold of a high-speed blow molding machine. The linkage mechanism includes a horizontal plate 9, a vertical plate 13 fixedly mounted at the bottom end of the horizontal plate 9, a rotating pair 15 rotatably connected to the bottom of the vertical plate 13, and connecting blocks 7 fixedly mounted at the top of the two vertical rods 6. The surfaces of the two connecting blocks 7 are provided with through rolling grooves, and the two ends of the rotating pair 15 are respectively rotatably connected to the corresponding rolling grooves.

[0022] Specifically, the rotating joint 15 at the bottom of the vertical plate 13 rolls with the rolling groove in the middle of the two connecting blocks 7. When the bottom mold 11 and the moving side mold 5 are closed, the rotating joint 15 rolls to both sides of the rolling groove. When the bottom mold 11 and the moving side mold 5 are separated, the rotating joint 15 rolls to the middle of the rolling groove, thereby realizing the linkage between the bottom mold 11 and the moving side mold 5.

[0023] Both sides of the horizontal plate 9 are fixedly provided with air blowing pipes 8, and the bottom of the two air blowing pipes 8 are fixedly installed with mounting plates 12. The bottom end of the mounting plates 12 is fixedly provided with two bottle blowing nozzles 16 that are connected to the air blowing pipes 8.

[0024] Specifically, the blowing operation can be achieved through the cooperation of the blowing pipe 8 and the blowing nozzle 16.

[0025] The bottom of the second fixed plate 2 and the movable slider 4 are both fixed with fixing strips 10, and the fixing strips 10 are fixedly connected to the corresponding movable side mold 5 and bottom mold 11 by bolts.

[0026] Specifically, the fixing strip 10 provides stable support for the moving side mold 5 and the bottom mold 11, ensuring the firmness of their installation.

[0027] Fixing seats 14 are fixed at the four corners of the first fixing plate 1 and the second fixing plate 2, and the fixing seats 14 are threadedly connected to the ends of the corresponding sliding rods 3.

[0028] Specifically, by setting the fixing seat 14, the end of the slide rod 3 can be fixed, thereby ensuring the firmness of the connection between the slide rod 3 and the first fixing plate 1 and the second fixing plate 2.

[0029] The first fixed plate 1, the second fixed plate 2, and the movable slider 4 are all the same in size and dimensions.

[0030] Specifically, by setting the size and dimensions of the first fixed plate 1, the second fixed plate 2, and the movable slider 4, the stable mold closing of the movable side mold 5 and the bottom mold 11 is ensured.

[0031] In specific implementation, when the moving side mold 5 separates from the bottom mold 11, the vertical rod 6 on the side of the moving slider 4 moves. The movement of the vertical rod 6 drives the connecting block 7 to move synchronously. The connecting block 7 causes the rotating pair 15 at the bottom of the vertical plate 13 to move to one side of the rolling groove. At the same time, the air blowing pipe 8 moves upward, causing the rotating pair 15 to slide towards the high point of the rolling groove. When the moving side mold 5 and the bottom mold 11 are closed, the air blowing pipe 8 moves downward, pushing the rotating pair 15 to slide towards the bottom of the rolling groove on the surface of the connecting block 7, thus realizing the mold closing between the moving side mold 5 and the bottom mold 11. Through the linkage mechanism between the moving side mold 5 and the bottom mold 11, the vibration and impact of the mechanism can be effectively reduced, the wear of parts can be reduced, the movement of the moving side mold 5 can be precisely controlled, the smoothness and reliability of the blow molding machine can be enhanced, and the high-speed performance of the whole machine can be improved.
