Abstract
Description
Technical Field
[0001] This utility model relates to the field of opening and closing mechanism technology, specifically to an opening and closing mechanism for shoe sole molds. Background Technology
[0002] Existing shoe sole forming equipment includes a base, a pressing mechanism, a fluid heating mechanism, and fluid pipelines. The shoe sole forming mold is installed on the base. During production, the shoe sole forming mold is opened, and the material is placed inside. Then, the fluid heating mechanism injects hot fluid into the water channel of the shoe sole forming mold through the fluid pipeline to heat the shoe sole forming mold. During this period, the pressing mechanism gradually applies pressure to the shoe sole forming mold, so that the material is formed into a shoe sole. After the shoe sole is formed and cooled, the shoe sole is removed from the shoe sole forming mold. An opening and closing mechanism is required for opening and closing the mold.
[0003] A search revealed a patent, CN221850878U, which discloses an opening and closing mechanism for a shoe sole mold. This mechanism includes a bottom frame, a top frame, an upper mold, a lower mold, and a pair of first and second connecting rods. A drive cylinder is located below the bottom frame and is hinged to the bottom frame via a first hinge assembly, with the cylinder positioned at an angle. The top frame is hinged to the bottom frame via a second hinge assembly. The upper mold is fixedly mounted on the bottom surface of the top frame, and the lower mold is fixedly mounted on the top surface of the bottom frame. The bottom end of each first connecting rod is hinged to the bottom frame via a third hinge assembly, and a rotating shaft is located between the top ends of the paired first connecting rods, passing through the telescopic rod of the drive cylinder. The top end of each second connecting rod is hinged to the top frame via a fourth hinge assembly, and the bottom end of each second connecting rod is fitted onto the outer periphery of the rotating shaft. By positioning the drive cylinder, which acts as the actuator, at an angle below the bottom frame, the previous installation difficulties are resolved.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] The aforementioned comparative document describes how the top frame is rotated by a start-up drive cylinder to open and close the shoe sole mold. However, since one end of the top frame in the aforementioned comparative document is far from its rotation axis, in actual use, the side of the mold away from the rotation axis may have poor sealing. Poor sealing can lead to shoe sole injection failure, reducing the applicability of the overall device. Therefore, there is an urgent need in the art to improve the opening and closing mechanism of the shoe sole mold to solve the defects of the prior art. Utility Model Content

[0028] Please see Figures 1-7 An opening and closing mechanism for a shoe sole mold includes a first support plate 1 and a second support plate 2 installed adjacent to each other. The second support plate 2 is provided with an arc-shaped seat 3. An arc-shaped groove 4 is opened on the side of the arc-shaped seat 3 near the first support plate 1. An arc-shaped toothed ring 5 is slidably connected in the arc-shaped groove 4. An upper mold 6 is provided at the end of the arc-shaped toothed ring 5 facing the first support plate 1. A lower mold 7 adapted to the upper mold 6 is provided on the first support plate 1. A reducer 19 is fixedly installed on one side of the arc-shaped seat 3. A drive motor 18 for driving the reducer 19 is fixedly installed on one side of the arc-shaped seat 3. A drive gear 20 fixedly installed to the output shaft of the reducer 19 is rotatably connected in the arc-shaped seat 3. The drive gear 20 meshes with one side of the arc-shaped toothed ring 5. A storage box 8 for storing materials is fixedly installed on one side of the first support plate 1. A flexible conveying hose 9 for conveying materials is fixedly installed between the storage box 8 and the upper mold 6.
[0029] Specifically, the upper mold 6 for shoe sole injection molding is installed at one end of the arc-shaped toothed ring 5, and the lower mold 7 is installed on the first support plate 1. When the shoe sole is injection molded, the drive motor 18 is started, and the output end of the drive motor 18 drives the reducer 19 to run. The output shaft of the reducer 19 drives the drive gear 20 located in the arc-shaped seat 3 to rotate. When the drive gear 20 rotates, it drives the arc-shaped toothed ring 5 located in the arc-shaped groove 4 to slide. The arc-shaped toothed ring 5 drives the upper mold 6 to move to the lower mold 7. The upper mold 6 and the lower mold 7 are closed. The conveying pump in the storage box 8 is turned on, and the raw material is conveyed to the cavity inside the upper mold 6 and the lower mold 7 through the elastic conveying hose 9. After the shoe sole is formed, the drive motor 18 is started in reverse to drive the upper mold 6 away from the lower mold 7. One end of the arc-shaped toothed ring 5 is installed in the middle of the back of the upper mold 6. Compared with the rotation of the shaft, the sealing effect when the upper mold 6 and the lower mold 7 are closed is improved, and the applicability of the overall device is improved.
[0030] As a technical optimization of this utility model, the second bearing plate 2 is slidably connected to a first sliding seat 10 for driving the arc-shaped seat 3 to move. The second bearing plate 2 is provided with a first sliding groove 11 adapted to the first sliding seat 10. A first adjusting threaded rod 12 is threadedly connected to the first sliding seat 10 through one side of the second bearing plate 2. A first limiting nut 13 is threadedly connected to the side of the first adjusting threaded rod 12. A second sliding seat 14 is fixedly installed at the lower part of the arc-shaped seat 3. A second sliding groove 15 adapted to the second sliding seat 14 is provided on the upper side of the first sliding seat 10. One side of the first sliding seat 10 extends to the outside of the first sliding groove 11. A second adjusting threaded rod 16 threadedly connected to the second sliding seat 14 through one side of the first sliding seat 10 is threadedly connected to the second sliding seat 14. A second limiting nut 17 is threadedly connected to the side of the second adjusting threaded rod 16.
[0031] Specifically, by rotating the second adjusting threaded rod 16, the second adjusting threaded rod 16 drives the second sliding seat 14 to slide within the second sliding groove 15. The second sliding seat 14 drives the arc-shaped seat 3 to move laterally. By rotating the first adjusting threaded rod 12, the first adjusting threaded rod 12 drives the first sliding seat 10 to slide within the first sliding groove 11. The first sliding seat 10 drives the arc-shaped seat 3 to move longitudinally, which facilitates the adjustment of the position of the arc-shaped seat 3 and improves the accuracy of the mold closing between the upper mold 6 and the lower mold 7. After the position of the arc-shaped seat 3 is adjusted, the first limiting nut 13 and the second limiting nut 17 are tightened to fix the position of the arc-shaped seat 3, further improving the applicability of the overall device.
[0032] As a technical optimization of this utility model, the first bearing plate 1 is provided with two symmetrical first clamping plates 21. A third sliding seat 22 is fixedly installed on the lower side of the first clamping plate 21. The upper part of the first bearing plate 1 is provided with two symmetrical third sliding grooves 23 that are adapted to the third sliding seats 22.

A fourth limiting nut 30 is threadedly connected to the side of the fourth adjusting threaded rod 29.
[0033] Specifically, the lower mold 7 is placed in a relatively central position on the first support plate 1. By rotating the third adjusting threaded rod 24, the threads of the third adjusting threaded rod 24 on the inner side of the third sliding groove 23 are reversed and symmetrical. When the third adjusting threaded rod 24 rotates, it drives the two third sliding seats 22 to move towards each other within the third sliding groove 23. The third sliding seats 22 drive the first clamping plate 21 to move, closely adhering to the opposite sides of the lower mold 7. Then, the fourth adjusting threaded rod 29 is rotated. The threads of the fourth adjusting threaded rod 29 on the inner side of the fourth sliding groove 28 are symmetrical and reversed. When the adjusting threaded rod 29 rotates, it drives the two fourth sliding seats 27 to move towards each other in the fourth sliding groove 28. The fourth sliding seats 27 drive the second clamping plate 26 to move. Several second clamping plates 26 are in close contact with the other two opposite sides of the lower mold 7. Then, tighten the third adjusting threaded rod 24, the fourth adjusting threaded rod 29, the third limiting nut 25 and the fourth limiting nut 30 to clamp and fix the lower mold 7. This facilitates quick positioning and clamping of the lower mold 7 and can position and fix lower molds 7 of different sizes, thus improving the applicability of the overall device.
[0034] As a technical optimization of this utility model, an installation block 31 is fixedly installed on the side of the upper mold 6, and an installation groove 32 adapted to the installation block 31 is opened at one end of the arc-shaped toothed ring 5 near the upper mold 6. An installation bolt 33 with one end threadedly connected to the installation block 31 passes through one side of the arc-shaped toothed ring 5.
[0035] Specifically, when installing the upper mold 6, the mounting block 31 on the side of the upper mold 6 is inserted into the mounting groove 32 at one end of the arc-shaped toothed ring 5, and one end of the mounting bolt 33 is threaded through the arc-shaped toothed ring 5 and the other end is threaded to the side of the mounting block 31. Tightening the mounting bolt 33 can fix the upper mold 6 in place, which is convenient for the installation or replacement of the upper mold 6 later.
