Description

Technical Field

[0001] This utility model relates to the field of mold changing technology, specifically a rotary mold changing mechanism. Background Technology

[0002] In modern industrial production, in order to meet diverse product demands, enterprises often need to frequently change molds of different specifications and types on the same production equipment. Traditional mold changing methods mainly rely on manual labor or simple mechanical auxiliary devices, which have problems such as low changing efficiency and high labor costs. In order to improve this situation, it is particularly important to develop a rotary mold changing mechanism.

[0003] Referring to a rotary mold changing mechanism (CN217141953U), the mechanism includes a base, a column fixedly connected to the top surface of the base, a first lifting mechanism at the top of the column, and a second lifting mechanism at the top of the first lifting mechanism. This mold changing mechanism uses a telescopic rod to lift a fixed plate, which in turn lifts an elliptical column via a rotating column. The elliptical column then lifts a connecting rod, which in turn lifts a rotating mold via a connecting block. This allows the rotating mold to automatically rise and fall, facilitating mold replacement. An elliptical fixing hole and a telescopic hole are provided to engage with the elliptical column and the connecting rod. When the elliptical column is lifted, it separates from the elliptical fixing hole. At this time, the rotating mold can rotate to the bottom of the rotating column via the connecting rod and the connecting block, allowing for mold rotation and replacement, reducing the difficulty of mold replacement. However, while this mold changing mechanism can be well applied, it is generally inconvenient to disassemble and assemble the mold body, making mold replacement and maintenance difficult. Therefore, it still presents some inconveniences and requires further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary mold changing mechanism to solve the problem that although the mold changing mechanism mentioned in the background art can be well applied, it is usually inconvenient to disassemble and assemble the mold body, and thus it is not easy to replace and maintain the mold body, and there are still some inconveniences in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary mold changing mechanism, comprising a base, a vertical plate fixed to the top of the base, a first motor mounted on the lower end of the surface of the vertical plate, a lead screw mounted on the top of the first motor, limit rails provided on the surface of the vertical plate on both sides of the lead screw, a lifting plate mounted on the outer wall of the upper end of the lead screw via a nut pair, the inner wall of the lifting plate slidably connected to the surface of the limit rails, bearing rods mounted on both sides of the surface of the lifting plate, a top seat mounted on the end of the two bearing rods away from the lifting plate, a transmission body located at the center of the bottom end of the top seat, a protective body located at the center of the bottom end of the transmission body, a disc located below the protective body, a plurality of placement seats located at the bottom end of the disc, a clamp mounted at the bottom end of the placement seats, a locking nut fixed on the outer wall of one end of the clamp, a locking bolt mounted on the outer wall of the other end of the clamp, one end of the locking bolt penetrating the clamp and threadedly connected to the locking nut, and an upper mold mounted on the bottom end of the placement seat inside the clamp.

[0006] Preferably, a processing table is provided at the top of the base in front of the upright plate, and a lower mold is installed at the top of the processing table. The processing table is provided to support and place the lower mold.

[0007] Preferably, a first shaft is rotatably mounted inside the transmission body, with both ends of the first shaft extending to the outside of the transmission body. The first shaft is used to accommodate the active bevel gear.

[0008] Preferably, an active bevel tooth is fixed on the outer wall of the first shaft inside the transmission body, and a driven bevel tooth is rotatably installed inside the first shaft below the active bevel tooth. The driven bevel tooth meshes with the active bevel tooth, and the meshing of the driven bevel tooth with the active bevel tooth drives the driven bevel tooth to rotate when the active bevel tooth rotates.

[0009] Preferably, a second shaft is installed at the center of the bottom end of the driven conical tooth. The bottom end of the second shaft extends to the outside of the protective body and connects to the top of the disc. The second shaft is provided to connect the driven conical tooth to the disc.

[0010] Preferably, a side connecting seat is provided on the outer wall of one side of the top seat, and a second motor is installed at the bottom end of the side connecting seat. One end of the second motor is connected to one end of the first shaft, so that the first shaft can be driven to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the rotary mold changing mechanism not only improves the convenience of mold changing mechanism maintenance, but also achieves the purpose of rotary switching of the upper mold, and also achieves the purpose of easy adjustment of the distance between the upper mold and the lower mold;

[0012] (1) By tightening the locking bolt, one end of the locking bolt is screwed out to the outside of the locking nut. At this time, the hoop is no longer tightly attached to the outer wall of the upper mold. Pulling the upper mold can remove it from the bottom of the placement seat. If the upper mold needs to be installed, tighten the locking bolt to pass it through the hoop and screw it into the locking nut so that the hoop is attached to the outer wall of the upper mold. The upper mold can then be installed at the bottom of the placement seat, which makes it easier to disassemble and replace the upper mold, thereby improving the convenience of mold replacement mechanism maintenance.

[0013] (2) The first shaft is driven to rotate by the second motor, which in turn drives the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear mesh with each other, and the diameter of the active bevel gear is smaller than the diameter of the driven bevel gear, the active bevel gear drives the second shaft to rotate via the driven bevel gear. This allows the angle of the disc to be adjusted horizontally slowly, so that several upper molds can be rotated and moved to the top of the lower mold as needed, thereby achieving the purpose of rotating the upper mold.

[0014] (3) The screw is rotated by the first motor, so that the nut pair on the outer wall of the screw slides on the outer wall of the screw, so that the lifting plate slides on the surface of the limit rail, thereby adjusting the height of the upper mold up and down, thus achieving the purpose of easily adjusting the distance between the upper mold and the lower mold.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 An embodiment of this utility model is provided: a rotary mold changing mechanism, including a base 1, a vertical plate 2 fixed to the top of the base 1, a processing table 17 provided at the top of the base 1 in front of the vertical plate 2, and a lower mold 18 installed at the top of the processing table 17.

[0023] In use, the processing table 17 is set up to support and place the lower mold 18;

[0024] A first motor 3 is installed at the lower end of the surface of the upright plate 2. A lead screw 4 is installed at the top of the first motor 3. Limiting rails 6 are provided on both sides of the surface of the upright plate 2. A lifting plate 5 is installed on the outer wall of the upper end of the lead screw 4 through a nut pair. The inner wall of the lifting plate 5 is slidably connected to the surface of the limiting rail 6. Bearing rods 7 are installed on both sides of the surface of the lifting plate 5. A top seat 8 is installed at the end of the two bearing rods 7 away from the lifting plate 5. A transmission body 21 is provided at the center of the bottom end of the top seat 8. A first shaft 11 is rotatably installed inside the transmission body 21. Both ends of the first shaft 11 extend to the outside of the transmission body 21.

[0025] In use, the first shaft 11 is set to accommodate the active bevel gear 22.

[0026] An active bevel gear 22 is fixed on the outer wall of the first shaft 11 inside the transmission body 21. A driven bevel gear 23 is rotatably installed inside the first shaft 11 below the active bevel gear 22. The driven bevel gear 23 meshes with the active bevel gear 22.

[0027] In use, the driven bevel tooth 23 meshes with the driving bevel tooth 22 so that the driving bevel tooth 22 drives the driven bevel tooth 23 to rotate when it rotates.

[0028] A second shaft 24 is installed at the center of the bottom end of the driven conical tooth 23. The bottom end of the second shaft 24 extends to the outside of the protective body 12 and is connected to the top of the disc 13.

[0029] In use, the second shaft 24 is provided to connect the driven bevel gear 23 to the disk 13.

[0030] A side connecting seat 9 is provided on the outer wall of one side of the top seat 8. A second motor 10 is installed at the bottom of the side connecting seat 9. One end of the second motor 10 is connected to one end of the first shaft 11.

[0031] In use, the second motor 10 is configured to drive the first shaft 11 to rotate;

[0032] A protective body 12 is provided at the center of the bottom of the transmission body 21. A disc 13 is provided below the protective body 12. Several placement seats 14 are provided at the bottom of the disc 13. A hoop 15 is installed at the bottom of the placement seat 14. A locking nut 19 is fixed on the outer wall of one end of the hoop 15. A locking bolt 20 is installed on the outer wall of the other end of the hoop 15. One end of the locking bolt 20 passes through the hoop 15 and is threadedly connected to the locking nut 19. An upper mold 16 is installed at the bottom of the placement seat 14 inside the hoop 15.

[0033] In this embodiment, the first shaft 11 is first rotated by the second motor 10, causing the first shaft 11 to rotate the active conical gear 22. This, in turn, causes the active conical gear 22 to rotate via the driven conical gear 23, which in turn drives the second shaft 24 to rotate. This allows for slow horizontal adjustment of the angle of the disc 13, enabling the transfer of several upper molds 16 to the upper mold 18 for switching operations. Then, the lead screw 4 is rotated by the first motor 3, causing the nut assembly on the outer wall of the lead screw 4 to slide. This allows the lifting plate 5 to slide on the surface of the limiting rail 6, thus adjusting the height of the upper mold 16 vertically. To facilitate adjustment of the distance between the upper mold 16 and the lower mold 18, the locking nut 19 is finally tightened to extend one end to the outside of the locking bolt 20. At this point, the hoop 15 is no longer tightly fitted to the outer wall of the upper mold 16. Pulling the upper mold 16 allows it to be detached from the bottom of the placement seat 14. If the upper mold 16 needs to be installed, the locking nut 19 is tightened to pass through the hoop 15 and screwed into the locking bolt 20, so that the hoop 15 fits against the outer wall of the upper mold 16. The upper mold 16 can then be installed at the bottom of the placement seat 14, making it easy to disassemble and replace the upper mold 16, thus completing the use of the mold replacement mechanism.
