Description

Technical Field

[0001] This application relates to the field of tire technology, and in particular to a flexible mold device for a tire shaping and vulcanizing machine and a tire shaping and vulcanizing machine. Background Technology

[0002] Current tire vulcanizing machines can be broadly classified into two types: mechanical double-mold vulcanizing machines and hydraulic double-mold vulcanizing machines. As the names suggest, mechanical double-mold vulcanizing machines primarily use a motor and reducer as output power, achieving the opening and closing pressure of the two molds through mechanical transmission. Hydraulic double-mold vulcanizing machines primarily use hydraulic drive as output power, achieving the opening and closing pressure of the two molds through hydraulic transmission. The mechanical double-mold vulcanizing machine was invented first, followed by the hydraulic double-mold vulcanizing machine. Due to limitations of the era and the technological environment at the time, the most significant drawback of the mechanical double-mold vulcanizing machine is uneven mold closing force, failing to meet the technological requirements of radial tires. The disadvantage of the hydraulic double-mold vulcanizing machine is the instability of the hydraulic system, which is prone to leakage. Summary of the Invention

[0020] To facilitate understanding of the movable mold device for a tire vulcanizing machine provided in this application embodiment, its application scenario is first described. The movable mold device for a tire vulcanizing machine provided in this application embodiment is applied in a tire vulcanizing machine. Current tire vulcanizing machines use hydraulic power as the drive, but hydraulic drives are prone to problems such as system instability and leakage. Therefore, this application embodiment provides a movable mold device for a tire vulcanizing machine to improve the driving effect of the movable mold. A detailed description follows with reference to specific drawings and embodiments.

[0021] refer to Figure 1 As shown, Figure 1This illustration shows a schematic diagram of the structure of the movable mold device for a tire vulcanizing machine according to an embodiment of this application. The movable mold device for a tire vulcanizing machine according to this embodiment mainly includes a movable mold support 10, a movable locking sleeve 60, and a drive mechanism. The movable mold support 10 supports the drive mechanism of the movable mold locking sleeve and is used to assemble the movable mold device for the tire vulcanizing machine. The movable locking sleeve 60 is used to connect the movable mold as needed, realizing the connection and disconnection of the movable mold. The drive mechanism drives the movement of the movable locking sleeve 60, including but not limited to the extension and retraction of the movable locking sleeve 60 and the rotation required when connecting and disconnecting from the movable mold. For ease of understanding, the specific structure of each part of the movable mold device for a tire vulcanizing machine according to an embodiment of this application is described in detail below with reference to the specific drawings.

[0022] Continue to refer to Figure 1 As shown, the movable mold support 10 provided in this embodiment is a frame structure that can be fixed on a tire shaping vulcanizing machine to support the entire device. The movable locking sleeve 60 can be inserted into the movable mold support 10 and can slide relative to it. Furthermore, the movable locking sleeve 60 can rotate relative to the movable mold support 10. When the movable locking sleeve 60 is assembled into the movable mold support 10, the first end of the movable locking sleeve 60 protrudes outside the movable mold support 10, and the first end of the movable mold is used to mate with the movable mold connecting flange 100 (a structure in which the movable mold and the movable locking sleeve 60 cooperate) in a slot. The other end of the movable locking sleeve 60 is the second end, which is located inside the movable mold support 10 and is used to connect to the servo motor linear drive mechanism 20 that drives the movable locking sleeve 60 to extend and retract.

[0023] Specifically, the servo motor linear drive mechanism 20 is fixed to the movable mold support 10, and the servo motor linear drive mechanism 20 is located outside the movable mold support 10. This servo motor linear drive mechanism 20 has a drive rod, which is nested with the movable locking sleeve 60 and used to drive the movable locking sleeve 60 to slide. Figure 1 The placement direction of the movable mold device of the tire shaping vulcanizing machine shown is the reference direction. The movable locking sleeve 60 can slide back and forth in the vertical direction. The extension and retraction direction of the drive rod is also in the vertical direction. Thus, the movable locking sleeve 60 can be driven to move back and forth in the vertical direction by the servo motor linear drive mechanism 20.

[0024] In addition to the servo motor linear drive mechanism 20 described above, this embodiment of the application also includes a swing mechanism 30, which is used to drive the movable locking sleeve 60 to swing relative to the movable mold support 10. By swinging the movable locking sleeve 60 through the swinging of the swing mechanism 30, the locking and unlocking of the slot and the movable mold connecting flange 100 are realized.

[0025] by Figure 1The placement direction of the movable mold device of the tire shaping vulcanizing machine shown is a reference direction. When the movable locking sleeve 60 needs to be connected to the movable mold, the movable locking sleeve 60 is first driven to descend to the first set position by the servo motor linear drive mechanism 20. At this time, the slot of the movable locking sleeve 60 is inserted into the movable mold connecting flange 100. Then, the movable locking sleeve 60 is driven to swing by the swing mechanism 30 at the first set angle, and the slot can lock the movable mold connecting flange 100, thereby locking the movable mold and the movable locking sleeve 60 in place. When it is necessary to unlock the movable mold, the movable locking sleeve 60 can be driven to swing in the opposite direction at the first set angle by the swing mechanism 30, and the slot of the movable locking sleeve 60 is released from the movable mold connecting flange 100. Then, the movable locking sleeve 60 is driven to rise to the second set position by the servo motor linear drive mechanism 20. At this time, the movable locking sleeve 60 is completely disengaged from the movable mold connecting flange 100.

[0026] As can be seen from the above description, the movable mold device for the tire shaping vulcanizing machine provided in this application embodiment uses a servo motor linear drive mechanism 20 to drive the movable locking sleeve 60 to slide, and a swing mechanism 30 to drive the movable locking sleeve 60 to rotate, which facilitates the connection between the movable locking sleeve 60 and the movable mold. In addition, the use of a servo motor linear drive mechanism 20 to drive the movable locking sleeve 60 to rise and fall is a simple and reliable drive mechanism.

[0027] Continue to refer to Figure 1 As shown, in a specific feasible implementation, the servo motor linear drive mechanism 20 provided in this application embodiment includes a servo motor 22 and an electric cylinder 21. The electric cylinder 21 is fixedly connected to the movable mold support 10, and the servo motor 22 is fixedly connected to the electric cylinder 21, and can output power to the electric cylinder 21. The aforementioned drive rod is the drive rod of the electric cylinder 21. When adopting the above solution, the electric cylinder 21 and the servo motor 22 form a module. When connected to the movable mold support 10, it is only necessary to fix the electric cylinder 21 to the movable mold support 10.

[0028] In a specific and feasible embodiment, the movable mold support 10 provided in this application includes a first connecting flange 11, which is used for fixed connection with the main structure of the tire vulcanizing machine. This fixes the entire device to the main structure of the tire vulcanizing machine.

[0029] In one specific implementation scheme, the movable mold support 10 is a frame structure, which includes the aforementioned first connecting flange 11, top support, and vertical support. The top support is disposed opposite to the first connecting flange 11, and the top support is fixedly connected to the first connecting flange 11 through the vertical support to form a frame structure. When cooperating with the servo motor linear drive mechanism 20 and the movable locking sleeve 60, the electric cylinder 21 is fixed on the top support and located outside the frame structure. The movable locking sleeve 60 passes through the first connecting flange 11 and can rotate and slide relative to the first connecting flange 11.

[0030] In addition, the movable mold device of the tire shaping vulcanizing machine also includes a second connecting flange 40, which is used for fixed connection with the main structure of the tire shaping vulcanizing machine. Figure 1 The placement direction of the movable mold device of the tire shaping vulcanizing machine shown is a reference direction. The first connecting flange 11 and the second connecting flange 40 are arranged vertically at intervals, with the first connecting flange 11 located above the second connecting flange 40. The second connecting flange 40 is nested on the movable locking sleeve 60 and close to the first end to support the movable locking sleeve 60 and ensure its stability during sliding and rotation. It should be understood that when the second connecting flange 40 is set, the movable locking sleeve 60 can rotate relative to the second connecting flange 40, and can also slide relative to the second connecting flange 40. When the movable locking sleeve 60 is connected to the second connecting flange 40, Continue to refer to Figure 1 and Figure 2 As shown, the swing mechanism 30 provided in this embodiment includes a mold-locking cylinder 31 and a mold-locking connecting rod 32 hinged to the mold-locking cylinder 31. The mold-locking cylinder 31 is rotatable relative to the movable mold support 10, while the mold-locking connecting rod 32 is fitted onto the movable locking sleeve 60 and can drive the movable locking sleeve 60 to rotate. For example, the cylinder body of the mold-locking cylinder 31 is rotatable relative to the movable mold support 10, and the piston rod of the mold-locking cylinder 31 is hinged to the mold-locking connecting rod 32, thereby forming a two-bar linkage mechanism. When the piston rod of the mold-locking cylinder 31 extends or retracts, it can drive the mold-locking connecting rod 32 to rotate, thereby driving the movable locking sleeve 60 to rotate.

[0031] When the mold clamping link 32 is connected to the movable locking sleeve 60, a spline can be provided on the mold clamping link 32, and a groove that mates with the spline is provided on the outer side wall of the movable locking sleeve 60, so that the movable locking sleeve 60 can slide relative to the mold clamping link 32, and the movable locking sleeve 60 can be driven to rotate when the mold clamping link 32 rotates.

[0032] In a specific example, one end of the mold-locking linkage 32 is fitted inside the frame structure, which facilitates the arrangement of the swing mechanism 30. When the mold-locking linkage 32 is inside the frame structure, the cylinder body of the mold-locking cylinder 31 can be hinged to the first connecting flange 11, which facilitates the arrangement of the mold-locking cylinder 31.

[0033] In one specific implementation, the movable locking sleeve 60 includes a nested inner rod 62 and an outer rod 61, wherein the inner rod 62 is nested within the drive rod, and the outer rod 61 is rotatable relative to the inner rod 62. Specifically, the outer rod 61 is connected to the locking mold connecting rod 32, and the outer rod 61 is provided with the aforementioned slot. In this configuration, the inner rod 62 is fixedly connected to the drive rod, and the drive rod can move the inner rod 62, simultaneously moving the outer rod 61. The outer rod 61 is rotatably connected to the inner rod 62; therefore, when the locking mold connecting rod 32 drives the outer rod 61 to rotate, the inner rod 62 does not rotate, thus ensuring a relatively stable connection between the inner rod 62 and the drive rod.

[0034] This application also provides a tire shaping vulcanizing machine, which includes the tire shaping vulcanizing machine movable mold device of any of the above claims.

[0035] In the above technical solution, the movable locking sleeve 60 is driven to slide by a servo motor linear drive mechanism 20, and the movable locking sleeve 60 is driven to rotate by a swing mechanism 30, which facilitates the connection between the movable locking sleeve 60 and the movable mold. In addition, the movable locking sleeve 60 is driven to rise and fall by a servo motor linear drive mechanism 20, which is simple and reliable.

[0036] One or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.

[0037] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
