[0023] like Figure 1-4 As shown in the schematic embodiment of the quick mold changing mechanism for a tire vulcanizing machine provided by this utility model, the quick mold changing mechanism for a tire vulcanizing machine includes at least: a mounting base 1, a connecting base 2, a locking tongue unit 3, and a driving unit 4; the top of the connecting base 2 is connected to the bottom of the mold; The top surface of the mounting base 1 is provided with a groove 11, the connecting base 2 is located in the groove 11, the connecting base 2 is provided with a limiting groove 21, and a locking tongue unit 3 is provided on each side of the connecting base 2. The locking tongue unit 3 includes a locking tongue 31 that is linearly slidably connected in the groove 11 and can be inserted into the end of the limiting groove 21, and a first elastic member 32 located on the side of the locking tongue 31 away from the connecting base 2 and whose two ends are respectively connected to the locking tongue 31 and the mounting base 1. The drive unit 4 includes a sliding part 41 that passes through the side wall of the groove 11 and is linearly slidably connected to the mounting base 1, and a functional part 42 located in the groove 11 and fixedly connected to the sliding part 41. The sliding direction of the sliding part 41 is perpendicular to the limiting through groove 21. Two first inclined surfaces 4221 are symmetrically arranged at the end of the functional part 42 near the connecting base 2, and the two locking tongues 31 respectively abut against the two first inclined surfaces 4221.

[0024] In the aforementioned rapid mold-changing mechanism for a tire vulcanizing machine, the two locking tongue units 3 and the connecting seat 2 constitute a bidirectional locking structure. By pushing the sliding part 41, the functional part 42 is driven to slide along a direction perpendicular to the limiting through groove 21. When the functional part 42 approaches the mounting seat 1, the two locking tongues 31 are disengaged from the limiting through groove 21 under the guidance of the two first inclined surfaces 4221, and the two first elastic elements 32 are in a compressed state. When the functional part 42 moves away from the mounting seat 1, the length of the two first elastic elements 32 is restored, and the two locking tongues 31 are pushed into the limiting through groove 21 by the two first elastic elements 32, thereby realizing rapid connection and rapid separation between the mounting seat 1 and the mold, solving the current technical problem of slow tire mold changing speed. The first elastic element 32 is preferably a spring.

[0025] In some embodiments, the functional unit 42 includes a connecting part 421 and driving parts 422 located on both sides of the connecting part 421; a sliding part 41 is connected to the connecting part 421, and two first inclined surfaces 4221 are located on the two driving parts 422 respectively. The two driving parts 422 respectively guide the movement of the two locking tongues 31. This functional unit 42 has a simple structure and is easy to manufacture. Its drivable locking tongue 31 structure can be a simple column, which helps to reduce the manufacturing difficulty and cost of the quick mold change mechanism of the tire vulcanizing machine.

[0026] In some embodiments, the latch 31 is provided with a guide groove 311 extending through the latch 31 along the sliding direction of the drive part 422. The two drive parts 422 slide within the two guide grooves 311 respectively, and the two first inclined surfaces 4221 abut against the inner walls of the two guide grooves 311 respectively. The two guide grooves 311 can help limit the sliding direction of the two drive parts 422.

[0027] In some embodiments, the inner wall of the guide groove 311 is provided with a second inclined surface 3111 that is adapted to the shape of the first inclined surface 4221, and the drive part 422 is in surface contact with the inner wall of the guide groove 311 to slow down the wear rate of the latch 31 and the drive part 422.

[0029] In some embodiments, the drive unit 4 further includes a second elastic member 43 connected to the side of the connecting portion 421 away from the sliding portion 41; when the two locking tongues 31 disengage from the limiting through groove 21, the second elastic member 43 is in a compressed state; when the second elastic member 43 returns to its length, the two locking tongues 31 insert into the limiting through groove 21 to achieve automatic reset of the drive unit 4. The second elastic member 43 is preferably a spring.

[0030] In some embodiments, the quick mold changing mechanism of the tire vulcanizing machine further includes a limiting strip 5, which is fixed to the bottom surface of the groove 11. Two drive units 422 respectively abut against both ends of the limiting strip 5, and the limiting strip 5 is located between the connecting part 421 and the connecting seat 2. Due to the restriction of the limiting strip 5, the two drive units 422 can maintain the same distance during pushing or disengaging from the locking tongue 31, so as to help the two drive units 422 smoothly enter and exit the two guide slots 311.

[0031] In some embodiments, the latch unit 3 further includes a guide rod 33 and a guide seat 34. The guide seat 34 is fixed to the mounting base 1. One end of the guide rod 33 is connected to the latch 31, and the other end of the guide rod 33 is slidably connected to the guide seat 34. A first elastic member 32 is sleeved on the guide rod 33 and is located between the guide seat 34 and the latch 31. The first elastic member 32 is connected to the mounting base 1 through the guide seat 34. Under the constraint of the guide rod 33, the first elastic member 32 can extend and retract in a constant direction.

[0032] In some embodiments, the mounting base 1 is further provided with two guide grooves 12 symmetrically arranged on both sides of the groove 11 and communicating with the groove 11, and two guide seats 34 are respectively located in the two guide grooves 12. The installation position of the two guide seats 34 on the mounting base 1 can be quickly determined by means of the guide grooves 12.

[0035] The mounting base 1 in the quick mold changing mechanism of the tire vulcanizing machine is installed on the working platform 7. The bottom surface of the lower mold 61 is connected to the top surface of the connecting base 2 in the quick mold changing mechanism of the tire vulcanizing machine. The lower mold 61 achieves quick connection and quick separation with the mounting base 1 through the two-way locking structure formed by the two locking tongue units 3 and the connecting base 2.

[0036] The support frame 8 is mounted on the work platform 7, and the lifting drive device 9 is mounted on the support frame 8. The upper mold 62, located above the lower mold 61, is connected to the output end of the lifting drive device 9. Two telescopic rods 10 are located on both sides of the upper mold 62, and the two ends of the telescopic rods 10 are connected to the support frame 8 and the upper mold 62, respectively.

[0037] It should be noted that the upper mold 62 can be connected to the output end of the lifting drive device 9 through the quick mold changing mechanism of the tire vulcanizing machine. The quick mold changing mechanism of the tire vulcanizing machine is inverted, and the mounting seat 1 is connected to the lifting drive device 9, and the connecting seat 2 is connected to the upper mold 62, which can realize the quick connection and quick separation of the upper mold 62 and the mounting seat 1.
