[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figure 1 and Figure 2As shown, this utility model provides a lockable bottom mold structure, which includes a housing 1, a rack 2, a gear 3, a guide rod 4, a mounting base 5, a bottom mold 6, a locking fastener 7, a mounting plate 8, and a rotation drive mechanism 9. The housing 1 has an internal cavity 10, and the top surface of the housing 1 has a recessed guide hole 11 communicating with the cavity 10. The rack 2 is mounted on one side of the guide rod 4. The rack 2 and the guide rod 4 pass through the guide hole 11 and the cavity 10. The guide rod 4 is slidably connected to the inner wall of the guide hole 11. The gear 3 is rotatably connected to the housing 1 and located in the cavity 1. Inside the housing 1, gear 3 meshes with rack 2. Rotation drive mechanism 9 is installed on housing 1. Rotation drive mechanism 9 drives gear 3 to rotate. Mounting seat 5 is installed on the top of rack 2 and / or the top of guide rod 4. Mounting plate 8 is installed on the bottom surface of bottom mold 6. The bottom surface of mounting plate 8 is provided with a protruding insert post 12. Mounting seat 5 is provided with insertion hole 13 and screw hole 14 communicating with one side of insertion hole 13. Locking fastener 7 is threaded to screw hole 14. Insert post 12 is inserted into insertion hole 13. Locking fastener 7 is used to lock insert post 12 in insertion hole 13.

[0023] In practical applications, the rotating drive mechanism 9 drives the gear 3 to rotate. The rotating gear 3 meshes with the rack 2 to drive the rack 2 and guide rod 4 to rise and fall relative to the box body 1. The rising and falling rack 2 and guide rod 4 drive the bottom mold 6 to rise and fall. During assembly, the box body 1 and the rotating drive mechanism 9 can be installed at the bottom of the box forming machine first. The rack 2 and guide rod 4, which are equipped with the mounting base 5, extend upward into the forming space of the box forming machine. At this time, the mounting plate 8, which is equipped with the bottom mold 6, is then installed on the mounting base 5. When assembling the mounting plate 8 and the mounting base 5, the insert 12 on the bottom surface of the mounting plate 8 is inserted into the insertion hole 13 of the mounting base 5. Finally, the locking fastener 7 is screwed into the screw hole 14 until the end of the locking fastener 7 abuts against the insert 12 to lock the insert 12 in the insertion hole 13, thereby firmly assembling the mounting plate 8 and the mounting base 5 together. The present invention has a simple structure and low cost. The mounting plate 8 and the mounting base 5 are firmly assembled and not easily separated. They are also easy to assemble and disassemble, making it convenient to quickly assemble and disassemble the mounting plate 8 together with the bottom mold 6 from the mounting base 5.

[0024] In this embodiment, the rotation drive mechanism 9 includes a reducer 15 mounted on one side plate of the housing 1 and a motor 16 mounted on the main body of the reducer 15 and drivenly connected to the input end of the reducer 15. The output end of the reducer 15 extends into the cavity 10 of the housing 1, and the gear 3 is fitted outside the output end of the reducer 15. In practical applications, the motor 16 drives the gear 3 to rotate through the reducer 15, and the rotating gear 3 meshes with the rack 2 to drive the rack 2 to move up and down.

[0025] In this embodiment, the locking bottom mold structure further includes a limiting plate 17 installed at the bottom end of the rack 2 and / or the bottom end of the guide rod 4. The limiting plate 17 is located below the housing 1 and is used to abut against the bottom surface of the housing 1. In practical applications, when the rack 2 and guide rod 4 rise to their highest limit position relative to the housing 1, the limiting plate 17 abuts against the bottom surface of the housing 1 to limit the rack 2 and guide rod 4 from continuing to rise and prevent the rack 2 and guide rod 4 from detaching from the housing 1.

[0026] In this embodiment, the limiting plate 17 is equipped with a sensing block 18, and a sensor 19 is provided at the bottom of the housing 1. The sensing block 18 is used to trigger the sensor 19, and the sensor 19 is electrically connected to the rotation drive mechanism 9. In practical applications, when the rack 2 and guide rod 4 drive the bottom mold 6 to rise to the highest position, the limiting plate 17 abuts against the bottom surface of the housing 1, the sensing block 18 triggers the sensor 19, and the sensor 19 sends a feedback signal to the rotation drive mechanism 9, causing the rotation drive mechanism 9 to stop driving the rack 2 to rise, preventing the rack 2 from rising excessively and detaching from the housing 1.

[0027] In this embodiment, a connecting plate 20 is installed at the bottom of the housing 1, and the sensor 19 is installed on the connecting plate 20, with the sensor 19 located below the housing 1. This structural design facilitates the installation and removal of the sensor 19.

[0028] In this embodiment, a guide block 21 is installed on the inner wall of the cavity 10, and the guide rod 4 is slidably connected to the guide block 21. During the lifting and lowering of the guide rod 4, the guide rod 4 and the guide block 21 slide together, so that the lifting and lowering of the guide rod 4 is smooth.

[0029] Specifically, guide rod 4 is a wear-resistant guide bar, which improves the wear resistance of guide rod 4.

[0030] Specifically, a lubrication ring is installed on the top surface of the housing 1, located above the guide hole 11. The lubrication ring is sleeved around the rack 2 and guide rod 4, and is used to lubricate the rack 2 and guide rod 4, reducing the frictional resistance between them. This makes the lifting and lowering of the rack 2 and guide rod 4 smoother, with a low failure rate and long service life. Because the lubrication ring is sleeved around the rack 2 and guide rod 4, it also serves as a dustproof element.

[0031] In this embodiment, the peripheral wall of the insertion post 12 is recessed with a groove 22, and the end of the locking fastener 7 can extend into the groove 22. During the process of screwing the locking fastener 7 into the screw hole 14, the end of the locking fastener 7 gradually extends into the groove 22 of the insertion post 12 until the end of the locking fastener 7 abuts against the inner wall of the groove 22, thereby locking the insertion post 12 into the insertion hole 13. This structural design allows for a secure locking of the insertion post 12, thereby securely locking the mounting plate 8 onto the mounting base 5.

[0032] Specifically, the locking component 7 is a locking screw.

[0033] In this embodiment, there are multiple grooves 22, which are arranged at equal intervals along the axial direction of the insert post 12. By inserting the fastener 7 into the grooves 22 at different heights on the insert post 12, the relative position of the insert post 12 and the mounting base 5 is locked, thereby adjusting the distance between the mounting plate 8 and the mounting base 5, and thus adjusting the distance between the bottom mold 6 and the mounting base 5, and further adjusting the height of the bottom mold 6 independently.

[0034] Specifically, the insert 12 is provided with axial scale lines. The scale lines allow the operator to visually observe the height adjustment values ​​of the mounting plate 8 and the insert 12 relative to the mounting base 5, which facilitates the operator to quickly and accurately adjust / fine-tune the distance between the mounting plate 8 and the mounting base 5.

[0035] In this embodiment, the insertion hole 13 is a non-circular hole, and the insertion post 12 is a non-cylinder, with the insertion post 12 and the insertion hole 13 being concave and convex respectively. This structural design prevents the insertion post 12 from rotating relative to the insertion hole 13, thus preventing the mounting plate 8 from rotating relative to the mounting base 5 and playing a role in preventing rotation.

[0036] In this embodiment, a buffer pad is provided on the bottom surface of the housing 1, which is used to abut against the limiting plate 17. The buffer pad plays a buffering role, preventing the limiting plate 17 from having a hard impact collision with the housing 1 and reducing noise.

[0037] Specifically, the lubrication ring includes a roughly square ring body. The square guide rod 4 and rack 2 slide through the central hole of the ring body. The inside of the ring body is provided with a receiving cavity for holding lubricating oil. The upper part of the ring body is provided with an opening that connects to the receiving cavity. A ring ring covering the opening is sealed and fitted on the top of the ring body. Several balls are evenly embedded on the inner wall of the ring body. The balls can rotate freely on the inner wall of the ring body. One side of the ball protrudes outside the inner wall of the ring body, and the other side of the ball extends into the receiving cavity. That is, the outer side of the ball protrudes from both sides of the inner wall. A retaining ring is threaded on the outer side of the ring body. The lower end face of the retaining ring is a slope with the inner side higher than the outer side. Several lateral pressure columns are evenly passed through the outer wall of the ring body. The lateral pressure columns extend radially along the ring body. One end of the lateral pressure columns extends into the receiving cavity of the ring body, and the other end of the lateral pressure columns abuts against the slope of the retaining ring. Several balls roll and abut against the outer sides of the guide rod 4 and rack 2 respectively. In practical applications, both guide rod 4 and rack 2 pass through the ring body. During the lifting and lowering process of guide rod 4 and rack 2, they respectively come into rolling contact with the balls, which carry out the lubricating oil in the receiving cavity. When the remaining lubricating oil in the receiving cavity is low, the lower inclined surface of the retaining ring is rotated downwards to press the lateral pressure column inwards, increasing the air pressure in the receiving cavity. This allows the lubricating oil in the receiving cavity to overflow more quickly and fully from the balls, and the overflowing lubricating oil adheres to guide rod 4 and rack 2 through the balls, or directly adheres to guide rod 4 and rack 2, thus achieving lubrication of rack 2 and guide rod 4. In addition, the ball bearings improve the lifting and lowering stability of guide rod 4 and rack 2.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
