Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing machines, and more specifically, to a vulcanizing machine locking device and a vulcanizing machine. Background Technology

[0002] After the tire-loading robot grabs the green tire and installs it in place, the mold closes under the action of the mold-opening and closing cylinder. To ensure the stability of the vulcanization process, the upper and lower vulcanization chambers need to be tightly connected by a mold-locking device. The mold-locking process plays a crucial role in the entire vulcanization process. The mold-locking mechanism of traditional semi-steel vulcanizing machines is just a simple locking tooth and locking ring structure. The four locking teeth and locking rings are independent. When mold locking is needed, they need to be manually locked one by one, which is time-consuming, labor-intensive, difficult, and poses certain safety hazards, and the work efficiency is also very low. Utility Model Content

[0003] The main purpose of this utility model is to provide a vulcanizing machine locking device and a vulcanizing machine to solve the problem of time-consuming and labor-intensive vulcanizing chamber locking in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a vulcanizing machine locking device is provided, comprising multiple locking heads, multiple locking sleeves, and a locking drive assembly. The locking heads are located at the lower part of the upper main plate of the vulcanizing chamber; the locking sleeves are rotatably disposed at the upper part of the lower bottom plate of the vulcanizing chamber, and each locking sleeve has a locking hole with the same shape as the locking head. When the upper main plate and the lower bottom plate are engaged, at least a portion of the locking head is located in the locking hole and locked in place with the locking sleeve; the locking drive assembly is drivenly connected to all the locking sleeves and drives all the locking sleeves to rotate synchronously, so as to synchronously change the locking relationship between the locking sleeves and the locking heads.

[0005] Furthermore, the mold-locking drive assembly includes a mold-locking drive component and a mold-locking transmission assembly. The mold-locking drive component is connected to the mold-locking transmission assembly or the mold sleeve drive assembly, and the mold-locking transmission assembly is connected to all the mold sleeves in a driving connection. The mold-locking drive component drives all the mold sleeves to rotate synchronously through the mold-locking transmission assembly.

[0006] Furthermore, the mold-locking transmission assembly includes multiple mold-locking transmission rods, with a mold-locking transmission rod provided between each two adjacent lock sleeves. The mold-locking transmission rods are connected to the two adjacent lock sleeves and drive the two adjacent lock sleeves to rotate synchronously.

[0007] Furthermore, the outer periphery of the lock sleeve has radially protruding protrusions, and the locking mold transmission rod is hinged to the protrusions of two adjacent lock sleeves.

[0008] Furthermore, the locking hole includes a first segment and a second segment connected axially in sequence. Along the direction in which the lock head extends into the locking hole, the first segment and the second segment are arranged in sequence. The shape of the first segment is the same as the shape of the lock head, and the size of the second segment is larger than that of the first segment. When the lock head is locked on the lock sleeve, the lock head passes through the first segment and extends into the second segment, and is circumferentially misaligned with the first segment.

[0009] Furthermore, the shape of the first segment and the shape of the lock head are both non-circular structures or both are eccentrically set circular structures.

[0010] Furthermore, the mold-locking device also includes a mold-locking detection component and a mold-locking sensing component. One of the mold-locking detection component and the mold-locking sensing component is disposed on the lower base plate, and the other of the mold-locking detection component and the mold-locking sensing component is disposed on the lock sleeve. The mold-locking detection component detects the position of the mold-locking sensing component to determine the state of the mold-locking device.

[0011] Furthermore, the vulcanizing machine locking device also includes a limiting element. The locking sleeve has a limiting end, and the limiting element is located on the rotation path of the limiting end. When the locking sleeve rotates to the position, the limiting end abuts against the limiting element to control the rotation range of the locking sleeve.

[0012] According to another aspect of the present invention, a vulcanizing machine is provided, including the vulcanizing machine mold locking device described above.

[0013] Furthermore, the vulcanizing machine also includes a mold adjustment device, which includes an adjusting rod that passes through the upper main plate and can adjust the vertical position of the upper main plate. The locking head of the vulcanizing machine's mold locking device is located at the bottom end of the adjusting rod.

[0014] By applying the technical solution of this utility model, a locking mold drive assembly is set up to drive all locking sleeves, enabling the locking mold drive component to drive all locking sleeves to rotate synchronously, thereby changing the locking relationship between the locking sleeves and the locking heads. The structure is simple and easy to operate. On the one hand, it realizes automatic locking of the vulcanizing chamber, which can improve work efficiency and reduce safety hazards compared with traditional manual locking, while reducing the operating cost of the vulcanizing machine locking device. On the other hand, it enables the locking relationship between each locking head and locking sleeve to change synchronously, so as to avoid the locking relationship being out of sync due to asynchronous rotation of each locking sleeve, which would cause the vulcanizing machine locking device to malfunction, thereby improving the service life of the vulcanizing machine locking device.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] To address the time-consuming and labor-intensive problem of mold locking in the vulcanizing chamber in existing technologies, this utility model provides a mold locking device for a vulcanizing machine and a vulcanizing machine.

[0028] like Figures 1 to 5The vulcanizing machine locking device 80 shown includes multiple locking heads 81, multiple locking sleeves 82, and a locking drive assembly. The locking heads 81 are located at the lower part of the upper main plate 41 of the vulcanizing chamber 40. The locking sleeves 82 are rotatably disposed at the upper part of the lower bottom plate 42 of the vulcanizing chamber 40. The locking sleeves 82 have locking holes 822 with the same shape as the locking heads 81. When the upper main plate 41 and the lower bottom plate 42 are engaged, at least a portion of the locking heads 81 are located in the locking holes 822 and locked in place with the locking sleeves 82. The locking drive assembly is drivenly connected to all the locking sleeves 82 and drives all the locking sleeves 82 to rotate synchronously, so as to synchronously change the locking relationship between the locking sleeves 82 and the locking heads 81.

[0029] This embodiment sets up a mold-locking drive assembly that is driven to all locking sleeves 82, enabling the mold-locking drive component 83 to drive all locking sleeves 82 to rotate synchronously, thereby changing the locking relationship between the locking sleeves 82 and the lock heads 81. The structure is simple and easy to operate. On the one hand, it realizes automatic mold locking of the vulcanizing chamber 40, which can improve work efficiency and reduce safety hazards compared with traditional manual mold locking, while reducing the operating cost of the vulcanizing machine mold-locking device 80. On the other hand, it enables the locking relationship between each lock head 81 and the locking sleeve 82 to change synchronously, so as to avoid the failure of the vulcanizing machine mold-locking device 80 caused by asynchronous rotation of each locking sleeve 82, thereby improving the service life of the vulcanizing machine mold-locking device 80.

[0030] It should be noted that the vulcanizing chamber 40 in this embodiment includes an upper main plate 41 and a lower bottom plate 42. The vulcanizing machine mold locking device 80 is disposed between the upper main plate 41 and the lower main plate. The vertical direction refers to the arrangement direction of the upper main plate 41 and the lower bottom plate 42, that is... Figure 1 The up and down directions in the middle.

[0031] In this embodiment, the mold-locking drive assembly includes a mold-locking drive component 83 and a mold-locking transmission assembly. The mold-locking drive component 83 is drivenly connected to the mold-locking transmission assembly or the locking sleeve 82, and the mold-locking transmission assembly is drivenly connected to all the locking sleeves 82. The mold-locking drive component 83 drives all the locking sleeves 82 to rotate synchronously through the mold-locking transmission assembly. Specifically, in this embodiment, the number and position of the locking heads 81 and locking sleeves 82 correspond one-to-one. The upper main plate 41 and the lower base plate 42 of the vulcanizing chamber 40 are both set as rectangular plate structures. The locking sleeves 82 are set on the side of the lower base plate 42 near the upper main plate 41, and one is set at each of the four corners of the lower base plate 42 to correspond one-to-one with the four locking heads 81 below the upper main plate 41. When the mold-locking drive component 83 drives the locking sleeves 82 to rotate, it can change the locking relationship between the locking sleeves 82 and the locking heads 81 to realize the locking relationship between the locking heads 81 and the locking sleeves 82. Specifically, when the locking sleeve 82 rotates until the shape of the locking hole 822 is axially aligned with the shape of the lock head 81, the lock head 81 and the locking sleeve 82 are in the unlocked state, and the lock head 81 can extend into or retract from the locking hole 822 of the locking sleeve 82. When the lock head 81 extends into the locking hole 822, and the locking sleeve 82 rotates until the shape of the locking hole 822 is axially misaligned with the shape of the lock head 81, the lock head 81 is fixed in the locking hole 822 and cannot be withdrawn from the locking hole 822, thereby achieving the locking of the upper main plate 41 and the lower base plate 42. In this embodiment, a locking mold drive component 83 is set to simultaneously drive the rotation of four locking sleeves 82 through the locking mold transmission assembly to achieve synchronous rotation of the four locking sleeves 82, thereby achieving synchronous unlocking and locking of each locking sleeve 82 and each lock head 81, thereby improving the synchronization and accuracy of the locking mold, and thus improving the reliability and safety of the vulcanizing machine locking mold device 80. Of course, the number of lock heads 81 and locking sleeves 82 can be adjusted as needed.

[0032] like Figure 2 , Figure 5 As shown, in this embodiment, the mold-locking transmission assembly includes multiple mold-locking transmission rods 84. A mold-locking transmission rod 84 is provided between each pair of adjacent lock sleeves 82. The mold-locking transmission rod 84 is connected to the two adjacent lock sleeves 82 and drives the two adjacent lock sleeves 82 to rotate synchronously, thereby achieving synchronous locking and unlocking of each lock sleeve 82 and each lock head 81. In this embodiment, the outer periphery of the lock sleeve 82 has a radially extending protrusion 821, and the mold-locking transmission rod 84 is hinged to the protrusion 821 of the two adjacent lock sleeves 82.

[0033] Specifically, in this embodiment, the locking sleeve 82 has a protrusion 821 near the lower base plate 42 for rotatable connection with the mold-locking transmission rod 84. The protrusion 821 is close to the edge of the lower base plate 42, so that the mold-locking transmission rod 84, which is hinged to the protrusion 821, is located further away from the center of the lower base plate 42 than the locking sleeve 82. The protrusion 821 is provided with a rotating shaft connected to the mold-locking transmission rod 84. Both ends of the mold-locking transmission rod 84 are provided with connecting holes, and the rotating shaft of the protrusion 821 passes through the connecting holes to realize the hinge connection between the mold-locking transmission rod 84 and the locking sleeve 82. Thus, the four locking sleeves 82 are equipped with three locking mold transmission rods 84 and one locking mold drive component 83. The locking mold drive component 83 is drivenly connected to one of the locking sleeves 82, and the locking mold transmission rods 84 connect the four locking sleeves 82. This allows the locking mold drive component 83 to simultaneously drive the rotation of the four locking sleeves 82 through the locking mold transmission rods 84, enabling each locking sleeve 82 to rotate simultaneously to a set angle position. This allows the locking hole 822 to fully lock with the lock head 81, effectively securing the upper main plate 41 and the lower base plate 42 together, i.e., locking the mold. When the locking mold drive component 83 drives one of the locking sleeves 82 to rotate, the other three locking sleeves 82 passively rotate synchronously with the other locking sleeve 82 through the locking mold transmission rods 84. This ensures that the locking and unlocking of each lock head 81 and each locking sleeve 82 are synchronized, thereby improving the synchronization and stability of the locking molds at various positions in the vulcanizing chamber 40. Optionally, the locking mold drive component 83 can be a cylinder, and it can be connected to a spherical bearing to drive the rotation of one of the locking sleeves 82. Of course, the mold clamping drive component 83 can also be a hydraulic cylinder, electric cylinder, etc.

[0034] In this embodiment, the locking hole 822 includes a first segment and a second segment connected axially in sequence. Along the direction in which the lock head 81 extends into the locking hole 822, the first segment and the second segment are arranged sequentially. The shape of the first segment is the same as the shape of the lock head 81, and the size of the second segment is larger than the first segment. When the lock head 81 is locked onto the lock sleeve 82, the lock head 81 passes through the first segment and extends into the second segment, and is circumferentially misaligned with the first segment. Specifically, in this embodiment, the lock head 81 enters the locking hole 822 from top to bottom; therefore, the first segment is on top and the second segment is on the bottom. When the lock head 81 enters the locking hole 822 from top to bottom, the shape of the lock head 81 is axially aligned with the shape of the first segment, that is, the projection of the lock head 81 on the lower base plate 42 coincides with the projection of the first segment on the lower base plate 42. This allows the lock head 81 to smoothly enter the second segment through the first segment. Then, driven by the locking mold drive 83, the lock sleeve 82 rotates circumferentially by a certain angle, causing the shape of the lock head 81 to be circumferentially misaligned with the shape of the first segment. This prevents the lock head 81 from disengaging from the first segment, thus locking the lock head 81 and the lock sleeve 82. To ensure that the lock head 81 can smoothly enter the second segment from the first segment, the second segment can be set as a circular hole, and the diameter of the second segment is not less than the maximum outer diameter of the lock head 81. Of course, the second segment can also be set as a hole of other shapes, as long as the lock head 81 can smoothly enter the second segment and rotate a certain angle within the second segment.

[0035] In this embodiment, to ensure flexible switching between locking and unlocking of the lock head 81 and the locking hole 822, the shape of the first segment and the shape of the lock head 81 are both non-circular structures or both are eccentrically arranged circular structures. This allows the first segment to both facilitate the smooth passage of the lock head 81 into the second segment and prevent the lock head 81 from dislodging from the locking hole 822 when it is in the second segment. Optionally, the lock head 81 can be configured as a spline structure, and correspondingly, the first segment can be configured as a spline hole to achieve the engagement of the lock head 81 and the locking hole 822. Of course, the lock head 81 and the locking hole 822 can also be configured as other shapes such as plum blossom shape or gear shape, as long as they can achieve locking and unlocking of the lock head 81 and the lock sleeve 82.

[0036] In this embodiment, the vulcanizing machine mold-locking device 80 further includes a mold-locking detection element 85 and a mold-locking sensing element 86. One of the mold-locking detection element 85 and the mold-locking sensing element 86 is disposed on the lower base plate 42, and the other of the mold-locking detection element 85 and the mold-locking sensing element 86 is disposed on the locking sleeve 82. The mold-locking detection element 85 detects the position of the mold-locking sensing element 86 to determine the state of the vulcanizing machine mold-locking device 80. Specifically, in this embodiment, the locking sleeve 82 and the lower base plate 42 have a certain gap along the axial direction, and the mold-locking detection element 85 and the mold-locking sensing element 86 are disposed within the axial gap between the locking sleeve 82 and the lower base plate 42. A mold-locking detection element 85 is provided on the upper surface of the lower base plate 42. The mold-locking detection element 85 is configured as a detection frame, and a proximity switch is provided on the detection frame. A mold-locking sensor 86 is provided on the side of the protrusion 821 of the locking sleeve 82 near the lower base plate 42. The mold-locking sensor 86 is configured as a detection column for detecting signals. Thus, both the mold-locking detection element 85 and the mold-locking sensor 86 are located between the protrusion 821 and the lower base plate 42. When the locking sleeve 82 rotates, the mold-locking sensor 86 rotates with the protrusion 821, thereby causing the mold-locking sensor 86 to move closer to or further away from the mold-locking detection element 85, thereby changing the positional relationship between the mold-locking detection element 85 and the mold-locking sensor 86, so as to detect the rotation angle of the locking sleeve 82, and thus detect whether the mold locking and opening are in place. The stroke of the mold-locking drive component 83 in this embodiment can be accurately calculated based on the rotation radius of the protrusion 821 and the required rotation angle of the locking sleeve 82. When the vulcanizing machine mold-locking device 80 is activated, the rotation angle of the protrusion 821 can be accurately controlled by the mold-locking drive component 83, thereby controlling the rotation angle of the locking sleeve 82, thus ensuring the accuracy of the mold-locking position and improving the working performance of the vulcanizing machine. The mold-locking detection component 85 and the mold-locking sensing component 86 further ensure the accuracy of the mold-locking position.

[0037] In this embodiment, the vulcanizing machine locking device 80 further includes a limiting member. The locking sleeve 82 has a limiting end, and the limiting member is located on the rotation path of the limiting end. When the locking sleeve 82 rotates to its position, the limiting end abuts against the limiting member to control the rotation range of the locking sleeve 82. Specifically, the protrusion 821 can serve as the limiting end. A limiting member is provided on the surface of the lower base plate 42 near the locking sleeve 82. When the protrusion 821 rotates to its position, the limiting member abuts against the protrusion 821, thereby preventing the protrusion 821 from continuing to rotate, thus ensuring the accuracy and reliability of the rotation angle of the locking sleeve 82.

[0038] like Figure 6The vulcanizing machine shown includes a base 10, a central column 20, multiple edge columns 30, a vulcanizing chamber 40, a tire loading mechanism 50 for loading tires and a tire unloading mechanism 60 for unloading tires, a mold adjusting device 70, a vulcanizing machine mold locking device 80, and a central mechanism 90. The central column 20 and edge columns 30 are both connected to the base 10, and are arranged in a V-shape, with the edge columns 30 located at the ends of the V-shape and the central column 20 located at the corners. The vulcanizing chamber 40 is located within the V-shape and includes an upper main plate 41 and a lower base plate 42. Adjacent central columns 20 and edge columns 30... In column 30, one of the middle column 20 and the edge column 30 is provided with a tire loading mechanism 50, and the other of the middle column 20 and the edge column 30 is provided with a tire unloading mechanism 60; the mold adjusting device 70 is provided on the upper main plate 41 and is movably disposed relative to the base 10, and can adjust the relative position between the upper main plate 41 and the lower base plate 42; the vulcanizing machine mold locking device 80 is provided between the upper main plate 41 and the lower base plate 42, and can lock the relative position when the upper main plate 41 and the lower base plate 42 are fastened together; the central mechanism 90 is connected to the base 10, at least a part of the central mechanism 90 is located in the vulcanizing chamber 40, and provides steam to the vulcanizing chamber 40.

[0039] This embodiment arranges the intermediate column 20 and edge columns 30 in a V-shape, and the tire loading mechanism 50 and tire unloading mechanism 60 do not have separate columns, but are instead mounted on the intermediate column 20 or edge column 30. This eliminates the need for separate support structures for the tire loading mechanism 50 and tire unloading mechanism 60 in traditional vulcanizing machines, integrating their structure and function into the edge column 30 and intermediate column 20. This allows the intermediate column 20 and edge column 30 to not only support the vulcanizing chamber 40, but also... The support of the tire loading mechanism 50 and the tire unloading mechanism 60 simplifies the structure of the vulcanizing machine, saves space, and reduces costs. Meanwhile, the vulcanizing chamber 40 is housed within a V-shaped structure, with the mold adjustment device 70, the vulcanizing machine mold locking device 80, and the central mechanism 90 arranged around it. This facilitates the operation of the mold adjustment device 70, the vulcanizing machine mold locking device 80, and the central mechanism 90 in adjusting and locking the mold, providing steam, etc., thus ensuring smooth tire vulcanization and improving work efficiency and energy conservation.

[0040] like Figure 3As shown, in this embodiment, the mold adjustment device 70 includes an adjusting rod 71 that passes through the upper main plate 41 and can adjust the vertical position of the upper main plate 41. The locking head 81 of the vulcanizing machine mold locking device 80 is located at the bottom end of the adjusting rod 71. In this embodiment, the locking head 81 is provided at the end of the adjusting rod 71 near the lower base plate 42, and the locking hole 822 is provided at the end of the locking sleeve 82 near the locking head 81. When it is necessary to lock the vulcanizing chamber 40, the locking head 81 extends into the locking hole 822 and locks with the locking sleeve 82.

[0041] In this embodiment, when the upper main plate 41 and the lower base plate 42 are fastened together, the position of the adjusting rod 71 relative to the lower base plate 42 is fixed. The adjusting rod 71 passes through the upper main plate 41 and is threadedly engaged with the upper main plate 41. When the adjusting rod 71 rotates, it drives the upper main plate 41 to move up and down relative to the lower base plate 42. This method of setting the mold adjustment device 70 on the upper main plate 41 of the vulcanizing chamber 40 makes the opening and closing of the vulcanizing chamber 40 more stable, thereby reducing the wear of the equipment and extending its service life. Specifically, in this embodiment, the adjusting rod 71 is set as a screw. The end of the screw near the lower base plate 42 is connected to the locking sleeve 82. The outer circumference of the screw is provided with external threads. The upper main plate 41 has a threaded hole, so that the screw can pass through the threaded hole of the upper main plate 41. When there is relative movement between the threaded hole and the screw, it can drive the movement of the upper main plate 41, thereby realizing mold adjustment. Compared to the traditional method of setting the mold adjustment device 70 on the lower base plate 42, the lower base plate 42 remains stationary when the upper main plate 41 moves. This means that when the force cylinder 43 located on the lower base plate 42 for mold closing is activated, the movement distance of the lower base plate 42 does not need to be considered. This helps to save the movement stroke of the force cylinder 43, thereby reducing the complexity of the vulcanizing machine structure and saving costs.

[0042] In this embodiment, the upper main plate 41 includes a plate body 411 and a nut 412. The nut 412 is rotatably connected to the plate body 411 and moves up and down synchronously with the plate body 411. An adjusting rod 71 passes through the nut 412 and is threadedly engaged with the nut 412. Specifically, the plate body 411 is rectangular and has a mounting hole. The nut 412 is rotatably disposed in the mounting hole, and the adjusting rod 71 passes through the nut 412. This allows the nut 412 to rotate relative to the adjusting rod 71, thereby causing the plate body 411 to move up and down, but not to rotate. This achieves the movement of the upper main plate 41, making the adjustment of the mold adjusting device 70 more precise and improving the quality of tire vulcanization. Optionally, the adjusting rod 71 can be a T-shaped screw, and the nut 412 can be a T-shaped nut 412.

[0043] In this embodiment, a connecting plate is provided on the side of the upper main plate 41 near the lower base plate 42. The connecting plate circumferentially fixes the adjusting rod 71 and the plate body 411, so that the adjusting rod 71 can only rotate relative to the nut 412 through the thread, and there will be no free rotation between the adjusting rod 71 and the plate body 411.

[0044] like Figure 4 As shown, in this embodiment, a force-applying cylinder 43 for opening and closing the mold is also provided on the side of the lower base plate 42 away from the mold-locking device 80 of the vulcanizing machine. Optionally, the cylinder rod of the force-applying cylinder 43 can be integrally set with the locking sleeve 82, thereby improving the reliability of mold opening and closing and mold locking, and simplifying the mechanism of the vulcanizing machine.

[0045] It should be noted that "multiple" in the above embodiments refers to at least two.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] 1. It solves the problem of time-consuming and labor-intensive mold locking in the vulcanization chamber in existing technologies;

[0048] 2. By setting the locking mold drive component to be connected to all locking sleeve drives, the locking mold drive component can drive all locking sleeves to rotate synchronously, thereby changing the locking relationship between the locking sleeve and the lock head. The structure is simple and easy to operate.

[0049] 3. On the one hand, it realizes automatic mold locking of the vulcanizing chamber, which can improve work efficiency and reduce safety hazards compared with traditional manual mold locking, while reducing the use cost of the vulcanizing machine mold locking device. On the other hand, it enables the locking relationship of each lock head and lock sleeve to change synchronously, so as to avoid the failure of the vulcanizing machine mold locking device caused by asynchronous rotation of each lock sleeve. This improves the service life of the vulcanizing machine mold locking device.
