Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] Referring to Figure 1-Figure 7 As shown in the figure, the embodiment provides a blow molding machine of a blow molding machine die closing mechanism, which comprises an operating table 1, one side of the operating table 1 is provided with a platform 7, a pair of die plates 5 is arranged above the platform 7, a connecting frame 6 is fixedly connected to the side wall of the die plate 5, a sliding block 8 is fixedly connected to the bottom of the connecting frame 6, the sliding block 8 is slidingly connected with the platform 7, one end of a connecting rod 11 is respectively hinged to the center of the two sliding blocks 8, a connecting seat 12 is hinged to the other end of the connecting rod 11, a driving assembly is fixedly connected to the side wall of the connecting seat 12, the driving assembly is fixedly connected with the platform 7, a connecting block 24 is fixedly connected to the bottom surface of the platform 7, the side wall of the connecting block 24 is fixedly connected with the output end of a second hydraulic rod 25, and the second hydraulic rod 25 is fixedly connected with the inner wall of the operating table 1.

[0033] The movement of the connecting block 24 is driven by the driving assembly, and the connecting rod 11 is further rotated, the rotation of the connecting rod 11 controls the movement of the sliding block 8, thereby controlling the opening and closing of the die plate 5, the original hydraulic structure is replaced by a mechanical mechanism, the stability during die closing is improved, and the synchronous movement of the two die plates 5 is realized by the arrangement of the connecting rod 11, thereby reducing the error.

The meshing transmission of the toothed plate 14 and the gear 15 converts the rotary motion into the linear motion of the die plate 5, compared with pure hydraulic drive, the transmission accuracy is higher, and the opening and closing speed can be adjusted by the gear ratio of the gear 15, thereby realizing more precise die closing control.

[0035] Further refine the scheme, a motor 22 is fixedly connected in the driving box 16, an output shaft of the motor 22 is fixedly connected with a worm 23, the worm 23 is engaged with a worm gear 20, a connecting shaft 21 is fixedly connected to the center of the worm gear 20, the connecting shaft 21 extends out of the driving box 16 and is fixedly connected with the gear 15.

[0038] Further detailing the solution, an extrusion mechanism 4 is mounted on the top surface of the operating table 1, connected to a feed hopper 3. The output end of the extrusion mechanism 4 is located above the template 5. Mounting the extrusion mechanism 4 directly on the operating table 1 shortens the embryo conveying path and reduces the risk of material cooling and hardening. The feed hopper 3 is connected to the extrusion mechanism 4, enabling continuous material feeding and improving production efficiency.

[0039] Further detailing the solution, the top surface of the operating table 1 is fixedly connected to a mounting plate 18 via bolts. The top surface of the mounting plate 18 is fixedly connected to a first hydraulic rod 17. The output end of the first hydraulic rod 17 is fixedly connected to a blow molding mechanism 19, which is located above the template 5. The first hydraulic rod 17 drives the blow molding mechanism 19 up and down, precisely controlling the docking position of the blow molding head and the mold cavity 28 to accommodate molds of different heights. The hydraulic drive provides stable pressure to ensure the quality of the blow molding.

[0040] Further detailing the solution, mold plates 5 are symmetrically provided with mold cavities 28, corresponding to the extrusion mechanism 4 and the blow molding mechanism 19, respectively. A circulating air duct 29 for rapid cooling is connected to the outer side of the mold cavity 28 below the blow molding mechanism 19. The circulating air duct 29 is connected to an air pump 30. The circulating air duct 29 is connected to the air pump 30, accelerating the cooling of the product in the mold cavity 28 through forced airflow, thereby shortening the molding cycle.

[0041] Further detailing the solution, a cutting assembly is installed within the operating table 1. This assembly includes a third hydraulic rod 26 fixedly mounted within the operating table 1. A cutter 27 is fixedly connected to the output end of the third hydraulic rod 26. This cutter 27 is used to cut the extruded embryo from the extrusion mechanism 4. The third hydraulic rod 26 drives the cutter 27 to quickly sever the extruded embryo, creating a smooth cut without manual intervention, thereby improving production automation. The position of the cutter 27 aligns with the mold cavity 28, ensuring that the cut embryo enters the mold directly after being cut, reducing waste.

[0042] Further detailing the solution, a base 2 is fixed to the bottom of the operating table 1, and a control panel is mounted on the base 2. The base 2 provides stable support and reduces equipment vibration. The control panel integrates control functions, enabling one-touch adjustment of parameters such as mold closing, blowing, and cooling, simplifying the operation process and reducing the need for manual intervention.

[0043] Workflow:

[0044] The base 2 at the bottom of the operating table 1 provides stable support. The operating panel starts the equipment and sets parameters. The second hydraulic rod 25 drives the platform 7 to move to the initial position. The raw material enters the extrusion mechanism 4 through the feed hopper 3. After heating and melting, it is extruded from the output end of the extrusion mechanism 4 as a tubular embryo, which is suspended above the template 5. The motor 22 drives the worm gear 20 to rotate through the worm 23. The worm gear 20 drives the gear 15 to rotate through the connecting shaft 21. The gear 15 engages with the tooth plate 14 to drive the connecting seat 12 to move horizontally. The connecting seat 12 pulls the double slider 8 along the limit rod 9 to close synchronously through the connecting rod 11. The template 5 moves in opposite directions until the mold is completely closed. The third hydraulic rod 26 drives the cutter 27 to move until the embryo is cut off. The limit block 13 ensures that the tooth plate 14 does not overtravel. The spring 10 continuously provides clamping force to reduce closing. When the rear mold template 5 retreats due to pressure, the second hydraulic rod 25 drives the connecting block 24 to move, and then drives the platform 7 to move, so that the embryo is located under the blow molding mechanism 19. The first hydraulic rod 17 drives the blow molding mechanism 19 to descend, and the blow molding head is inserted into the embryo in the mold cavity 28. Compressed air is introduced to expand the embryo and fit the wall of the mold cavity 28 to form the product contour. At this time, the drive component controls the template 5 to open, and the second hydraulic rod 25 drives the platform 7 to return to its original position. Then the drive component closes the template 5. At this time, the molded product is located in another mold cavity 28. The air pump 30 is started, and the air flow in the circulating air duct 29 accelerates the cooling of the product in the mold cavity 28. At the same time, the embryo extruded by the extrusion mechanism 4 falls into the mold cavity 28. This is repeated to send the molded product to the conveyor belt for transportation to realize assembly line production.
