Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to a movable mold operating device and a vulcanizing machine. Background Technology

[0002] The tire curing machine is a key piece of equipment in the tire production process. It mainly consists of a movable mold, a mold closing mechanism, a mold locking mechanism, and a movable mold operating device. The movable mold operating device is used to control the movable mold to complete the opening and closing actions.

[0003] Currently, the sliding mold control device of a vulcanizing machine is generally driven by a hydraulic cylinder. The hydraulic cylinder and pipeline are arranged on the upper crossbeam structure of the vulcanizing machine. When a leak occurs, the oil will flow into the vulcanizing chamber, thereby contaminating the tire mold and the tire surface, causing a very serious adverse effect on tire quality. At the same time, the hydraulic cylinder's reading and control of the piston rod's start and stop position through the displacement sensor is inaccurate and has low operating efficiency. It cannot accurately control the opening and closing positions of the sliding mold, which will also have an adverse effect on the vulcanized tire. Summary of the Invention

[0033] 1. The movable mold control device uses a lead screw and lead screw nut for transmission, which has high transmission accuracy, precise motion control, and high transmission efficiency, which is conducive to improving the quality of tire vulcanization and vulcanization production efficiency. Compared with the existing hydraulic cylinder drive, it avoids the risk of poor tire appearance quality caused by oil leakage. The movable mold control device has a longer service life than the hydraulic cylinder, fewer failures, compact space, and high utilization rate.

[0034] 2. The structure of the lead screw nut being clamped by the guide plate and the connecting shaft makes the force on the lead screw nut more reasonable.

For the lead screw nut, the force stability is good, avoiding excessive local force that could lead to deformation or damage.

[0035] 3. Compared with the existing hydraulic drive, the screw and screw nut can drive the screw to reverse during the mold closing process when there is an upward force on the connecting shaft, so as to avoid the problem of rigid contact of the connecting shaft causing internal stress and damage to the components.

[0036] 4. The support mechanism provides multiple guides for the up-and-down movement of the connecting shaft, ensuring the accuracy of the connecting shaft's movement; not only does the support base guide the connecting shaft using the first guide hole, but the cooperation between the optical axis and the guide plate also achieves the function of guiding the connecting shaft.

[0037] 5. The technical solution of this application also provides a new rotating shaft control scheme.

[0058] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0059] On the one hand, please refer to Figure 1 , Figure 2This invention provides a first embodiment of a movable mold operating device, comprising a drive mechanism 100, a support mechanism 200, a control mechanism 300, and a transmission mechanism 400. The support mechanism 200 is fixedly mounted on the upper plate 700 of the vulcanizing machine, serving as a support carrier for the movable mold operating device and providing mounting support for the drive mechanism 100, control mechanism 300, and transmission mechanism 400. The upper plate 700 is a component of the upper crossbeam structure; during the opening and closing of the tire mold, the upper plate 700 drives the movable mold operating device to rise and fall together; this is prior art. The drive mechanism 100 inputs power to the transmission mechanism 400, which drives the mold connecting plate 500 to rise and fall. The control mechanism 300 can control the locking or disengagement of the transmission mechanism 400 and the mold connecting plate 500.

[0060] For details, please refer to Figure 3 The support mechanism 200 includes a drive mounting base 210, a lead screw fixing base 220, and a support base 240. The drive mounting base 210 is fixedly disposed on the upper side of the lead screw fixing base 220, and the drive mechanism 100 is disposed on the drive mounting base 210. The support base 240 is located on the lower side of the lead screw fixing base 220, and a plurality of optical shafts 230 are provided between the two; the two ends of the optical shafts 230 are respectively fixedly connected to the support base 240 and the lead screw fixing base 220. The support base 240 is fixedly mounted on the upper plate 700. When the movable mold operating device is working, the support base 240 maintains a relatively fixed and stationary position relative to the upper plate 700.

[0061] In addition, the drive mounting base 210 and the lead screw fixing base 220 can be designed as an integral structure; depending on the structural design requirements, the drive mounting base 210 and the lead screw fixing base 220 can also be set as separate parts, which are processed separately and then assembled and fixed into one piece; preferably, a detachable connection method is used for fixing.

[0062] The transmission mechanism 400 includes a lead screw 410, a guide plate 420, a lead screw nut 430, a connecting shaft 440, a coupling sleeve 450, and a rotating shaft 460. The lead screw 410 is connected to the drive mechanism 100, and inputs power to drive the lead screw nut 430, the connecting shaft 440, the guide plate 420, the coupling sleeve 450, and the rotating shaft 460 to move up and down synchronously.

[0063] The lead screw 410 includes a threaded transmission part and an unthreaded smooth shaft part. A shoulder is formed at the connection between the smooth shaft part and the transmission part. The smooth shaft part at the upper part of the lead screw 410 is rotatably mounted on the lead screw fixing seat 220 through a bearing assembly, bearing cover, etc., and is connected to the drive mechanism 100 for transmission. The lower end of the lead screw 410 extends to the lower side of the lead screw fixing seat 220.

[0064] The lead screw nut 430 is threadedly connected to the lead screw 410 and is located below the lead screw fixing seat 220. The lead screw nut 430 has a radially protruding snap-fit ​​portion on its outer wall. A guide plate 420 and a connecting shaft 440 are located on the upper and lower sides of the snap-fit ​​portion, respectively, clamping the snap-fit ​​portion. The guide plate 420 and the connecting shaft 440 are fixedly connected. A circumferential limiting structure is also provided between the guide plate 420 and the snap-fit ​​portion and / or between the connecting shaft 440 and the lead screw nut 430. For example, the snap-fit ​​portion forms an external spline, and the guide plate 420 engages with the spline, allowing the lead screw nut 430 to convert the rotation of the lead screw 410 into axial movement. The guide plate 420 and the connecting shaft 440 rise and fall synchronously with the lead screw nut 430. For example, the snap-fit ​​portion can be an annular flange, with the guide plate 420 and the connecting shaft 440 abutting against the upper and lower sides of the flange, respectively.

[0065] The guide plate 420 is slidably connected to at least one optical axis 230, ensuring that when the lead screw 410 rotates, the lead screw nut 430 moves up and down instead of rotating. Furthermore, an auxiliary guide component 421 is provided between the optical axis 230 and the guide plate 420; the auxiliary guide component 421 can be a bushing, a self-lubricating bearing, a linear bearing, etc.; the auxiliary guide component 421 is sleeved on the outside of the optical axis 230 and fixed on the guide plate 420, cooperating with the optical axis 230 to guide the guide plate 420 and the lead screw nut 430. When the lead screw 410 rotates, the lead screw nut 430 drives the connecting shaft 440 and the guide plate 420 to move up and down along the optical axis 230, thus converting the rotational motion of the lead screw 410 into the linear motion of the lead screw nut 430 and the guide plate 420.

[0066] The support mechanism 200 preferably has four optical axes 230, which work together to support the support base 240 and the lead screw fixing base 220, as well as guide the guide plate 420. The four optical axes 230 are evenly distributed on the outer circumference of the lead screw 410.

[0067] Two optical axes 230 serve only to support and connect the lead screw fixing seat 220 and the support seat 240, while the other two optical axes 230 are slidably connected to the guide plate 420, providing not only support but also guidance for the guide plate 420. Figure 11 As shown.

[0068] Or, such as Figure 12 As shown, the guide plate 420 is slidably connected to the four optical axes 230, and the four optical axes 230 simultaneously serve as support and guide.

[0069] Furthermore, the connecting shaft 440 and the guide plate 420 are fixed with screws, bolts, pins and other connecting parts. A clearance groove is provided below the lead screw fixing seat 220. The position of the clearance groove corresponds to the position of the connecting part. The part of the connecting part that protrudes upward from the guide plate 420 can enter the clearance groove, which further saves space in the height of the device. The structure is compact and occupies little space.

[0070] A lead screw hole is provided on the upper end face of the connecting shaft 440, and the lead screw 410 is located in the lead screw hole with clearance fit; this helps to improve the operational stability of the lead screw 410.

[0071] like Figure 4 As shown, the support base 240 is provided with a first guide hole 241, and the lower end of the connecting shaft 440 passes through the first guide hole 241 and extends to the lower side of the support base 240. The connecting shaft 440 is slidably engaged with the first guide hole 241 and moves up and down under the guidance of the first guide hole 241.

[0072] Preferably, a guide sleeve 250 is provided on the inner wall of the first guide hole 241. Specifically, the first guide hole 241 is a stepped hole with a large upper diameter and a small lower inner diameter, thus forming a shoulder. The lower end of the guide sleeve 250 abuts against the shoulder, and the upper end is fixed and limited by a limiting ring 260. The guide sleeve 250 is fixed in the first guide hole 241, and the detachable fixing method makes it easy to replace the guide sleeve 250. The guide sleeve 250 can guide the movement of the connecting shaft 440, and at the same time, it has the functions of reducing friction and increasing lubrication.

[0073] The lower end of the connecting shaft 440 is rotatably connected to the rotating shaft 460 via a coupling sleeve 450. The control mechanism 300 drives the rotating shaft 460 to rotate, thereby locking and unlocking the rotating shaft 460 and the mold connecting plate 500. Figure 3 and Figure 5 As shown, the control mechanism 300 includes a drive shaft 330 and a power assembly. The drive shaft 330 is parallel to the rotating shaft 460, and the two are connected by a transmission and rotate synchronously. Exemplarily, a driven gear 310 is fixedly mounted on the rotating shaft 460, and a drive gear 320 is fixedly mounted on the drive shaft 330. The driven gear 310 and the drive gear 320 mesh and transmit power.

[0074] like Figure 5 As shown, a support plate 360 ​​is rotatably mounted on the rotating shaft 460. The lower end of the drive shaft 330 is rotatably connected to the support plate 360, and the drive shaft 330 and the support plate 360 ​​rise and fall with the rotating shaft 460. A second guide hole 242 is provided at the position corresponding to the drive shaft 330 on the support base 240. A communicating window 243 is opened on a partial sidewall of the second guide hole 242. The upper end of the drive shaft 330 extends into the second guide hole 242 and slides into it. The second guide hole 242 restricts the position of the drive shaft 330, allowing only the drive shaft 330 to rise and fall.

[0075] The power assembly controls the drive shaft 330 to rotate at a certain angle. The drive shaft 330 drives the drive gear 320, the driven gear 310, and the rotating shaft 460 to rotate at a corresponding angle. The rotation of the rotating shaft 460 allows it to connect to or disconnect from the mold connecting plate 500. The connection method between the mold connecting plate 500 and the rotating shaft 460 is existing technology and is not shown in detail in the figure. For example, the upper end of the mold connecting plate 500 is provided with a protruding cross-shaped spline, and the lower end face of the rotating shaft 460 is provided with a connecting cavity. The lower end of the connecting cavity has a cross-shaped opening. When the cross-shaped key teeth of the mold connecting plate 500 are aligned with the cross-shaped opening of the rotating shaft 460, the two can be inserted or separated. When the upper end of the mold connecting plate 500 is inserted into the rotating shaft 460, rotating it to offset the key teeth and the opening allows the rotating shaft 460 to connect to the mold connecting plate 500.

[0076] As one embodiment of the power component, such as Figure 1-6 As shown, the power assembly includes a rotating arm 350 and a first drive element 340. The first drive element 340 can be a telescopic controllable and driveable device element such as a cylinder, hydraulic cylinder, or electric cylinder. A support is fixed on the support base 240 or the upper plate 700. The fixed end of the first drive element 340 is hinged to the support, and the telescopic end is hinged to the rotating arm 350. The rotating arm 350 passes through the connecting window 243 and is connected to the drive shaft 330, achieving the effect that the two can slide relative to each other in the axial direction but rotate synchronously. For example, the first drive element 340 is a cylinder, with the cylinder body hinged to the seat body set on the upper plate 700, and the piston rod hinged to the rotating arm 350. The cross-section of the mating part of the drive shaft 330 and the rotating arm 350 is a rectangular or similar non-circular cross-section, and the rotating arm 350 is provided with a connecting hole adapted to the shape of the drive shaft 330. The rotating arm 350 is fitted onto the outside of the drive shaft 330 through the connecting hole, and the two can slide relative to each other in the axial direction and rotate synchronously in the circumferential direction.

[0077] As another embodiment of the power component, such as Figure 7-10 As shown, the power assembly includes a hollow shaft motor 370, which is fixedly mounted on a support base 240. The output shaft of the hollow shaft motor 370 is coaxial with the second guide hole 242. The drive shaft 330 is located inside the output shaft of the hollow shaft motor 370. The cross-section of the mating part between the output shaft of the hollow shaft motor 370 and the drive shaft 330 is non-circular, allowing them to rotate synchronously. The output shaft of the hollow shaft motor 370 and the drive shaft 330 are clearance-fitted, allowing the hollow shaft motor 370 to be fixedly mounted on the support base 240, and the drive shaft 330 to move axially relative to the hollow shaft motor 370.

[0078] The drive mechanism 100 includes a motor 110 and a reducer 120; the reducer 120 is fixed to the drive mounting base 210, and the motor 110 is directly connected to the reducer 120. The lead screw 410 is connected to the reducer 120 at the top, and preferably one end of the lead screw 410 is machined with a keyway for key connection with the inner hole of the reducer 120 to prevent rotation.

[0079] In the first embodiment of the movable mold operating device, such as Figure 1 As shown, the output shaft of the motor 110 is parallel and offset to the lead screw 410, and the input and output ends of the reducer 120 are located on the same side of the reducer 120; this can save space in terms of height.

[0080] As a second embodiment of the movable mold control device, such as Figure 13 As shown, unlike the first embodiment, the output shaft of the motor 110 is perpendicular to the lead screw 410, and the two have a 90° angle, which can also save space in terms of height.

[0081] As a third embodiment of the movable mold control device, such as Figure 14 As shown, unlike the first embodiment, the output shaft of the motor 110 is coaxial with the lead screw 410, which can be applied to situations where there is insufficient circumferential space.

[0082] Furthermore, at least one detection element 600 is provided on the travel of the lead screw nut 430 to detect whether the lead screw nut 430 has returned to the zero position; the detection element 600 can be a proximity switch, and the detection element 600 is fixedly installed on the support base 240 by a support rod. The device clears the accumulated data and calibrates the position data once each time it is activated.

[0083] When the flexible mold operating device is in use, the motor 110 drives the screw 410 to rotate through the reducer 120 to achieve the effect of speed reduction and torque increase. Since precise control of the mold opening and closing stroke is required, the motor 110 is preferably a servo motor, which uses its position mode to achieve precise control of the movement position.

[0084] Under the constraint of the guide plate 420, the screw nut 430 and the screw 410 realize the conversion of helical motion into linear motion, which drives the connecting shaft 440 to move up and down. Since the guide plate 420 and the connecting shaft 440 abut against the upper and lower sides of the locking part of the screw nut 430 respectively, whether the motor 110 drives the connecting shaft 440 to move downward or upward, multiple surfaces of the screw nut 430 are subjected to force, avoiding local force deformation.

[0085] The structure of the flexible mold control device not only enables mold opening but also improves the stress on the connecting shaft 440. Specifically, during mold closing, the guide ring fixed on the upper plate 700 pushes the patterned block to retract, causing it to slide inwards. During this process, the distance between the mold connecting plate 500 and the upper plate 700 gradually decreases. The mold connecting plate 500 pushes the lead screw nut 430 upwards relative to the upper plate 700, pushing the lead screw 410 to rotate. The motor 110 also experiences a passive rotation, thus relieving the internal force and preventing the connecting shaft 440 from being subjected to long-term stress, which could affect its service life.

[0086] On the other hand, a vulcanizing machine that uses the aforementioned movable mold operating device not only saves space and has high transmission accuracy, but also has a compact structure and occupies less space compared to hydraulic drive.

[0087] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
