The upper mold locking member is provided with a plum blossom tooth, and the lower mold locking member is provided with a plum blossom tooth groove that can cooperate with the plum blossom tooth. By driving the lower mold locking member to rotate, the plum blossom tooth groove rotates and locks the plum blossom tooth in a misaligned manner, preventing the upper and lower mold locking members from moving in the vertical direction, thereby locking the upper and lower molds.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0033] like Figures 1 to 15As shown, the present invention discloses a tire vulcanizer 1 with a clamping mechanism, comprising a frame 10, an upper template 11 movably arranged on the frame 10, an upper heating element (not shown) and an upper mold 12 arranged on the upper template 11; a support frame 20, a lower template 21 arranged on the support frame 20, and a pressurizing unit 22, a lower heating element 23 and a lower mold 24 arranged in sequence, wherein the pressurizing unit 22 is arranged on the lower template 21; wherein the upper template 11 is further provided with a plurality of upper mold locking members 30, and the lower template 21 is provided with A plurality of lower mold locking members 40, the upper mold locking member 30 and the lower mold locking member 40 are arranged opposite to each other; and a locking mechanism 50 is also provided on the lower mold plate 21 or the upper mold plate 11. When the upper mold 12 and the lower mold 24 are closed, the upper mold locking member 30 and the lower mold locking member 40 are driven to reach the initial closing position, and the upper mold locking member 30 and the lower mold locking member 40 are initially locked by the locking mechanism 50, and then the pressure unit 22 provides pressure so that the locking mechanism 50 is fully fitted with the upper mold locking member 30 and the lower mold locking member 40 to achieve complete locking.

[0034] It should be noted that the pressurizing unit 22 can be pneumatic or hydraulic, and is used to apply pressure to completely fix the positions of the upper mold 12 and the lower mold 24, preventing them from moving during the tire vulcanization process. The upper heating element is used to heat the upper mold 12, and the lower heating element 23 is used to heat the lower mold 24. The figures and embodiments illustrate and describe only the example of a clamping mechanism 50 disposed on the lower mold plate 21.

[0035] like Figure 2 and 3 As shown, the clamping mechanism 50 of the present invention includes a clamping drive source 51 and a synchronous transmission mechanism 52 fixedly disposed on the lower mold plate 21 or the upper mold plate 11, as well as a plurality of clamping assemblies 53. The clamping drive source 51 is connected to the plurality of clamping assemblies 53 via the synchronous transmission mechanism 52. The clamping drive source 51 drives the plurality of clamping assemblies 53 to move synchronously via the synchronous transmission mechanism 52, thereby performing preliminary clamping on the plurality of upper mold locking members 30 and the plurality of lower mold locking members 40 that have reached the preliminary mold closing position. Of course, multiple clamping drive sources 51 may also be provided, each connected to one or at least two clamping assemblies 53, so that multiple sets of clamping drive sources 51 can control multiple clamping assemblies 53.

[0036] The synchronous transmission mechanism 52 described in the present invention includes a first movable member 521 that can be moved along a first direction (such as the X-axis direction), one end of the first movable member 521 is connected to the clamping drive source 51, and the first movable member 521 can be fixed or hinged to the clamping drive source 51, and also includes a first connecting rod assembly 522 and a second connecting rod assembly 523 that are respectively hinged to the first movable member 521, and the first connecting rod assembly 522 and the second connecting rod assembly 523 are symmetrically arranged along the straight line where the first direction is located, and also includes two groups of secondary synchronous mechanisms 524 that are respectively hinged to the first connecting rod assembly 522 and the second connecting rod assembly 523, that is, one group of secondary synchronous mechanisms 524 is hinged to the first connecting rod assembly 522, and the other group of secondary synchronous mechanisms 524 is hinged to the second connecting rod assembly 523.

[0037] The secondary synchronization mechanism 524 includes a second movable member 5241 movably arranged along a second direction (e.g., the Y-axis direction), the first connecting rod assembly 522 and the second connecting rod assembly 523 are respectively hingedly connected to the second movable member 5241 in the corresponding secondary synchronization mechanism, and further includes a third connecting rod assembly 5242 and a fourth connecting rod assembly 5243 respectively hingedly connected to the second movable member 5241. The third connecting rod assembly 5242 and the fourth connecting rod assembly 5243 are symmetrically arranged along a line in the second direction, and the third connecting rod assembly 5242 and the fourth connecting rod assembly 5243 are respectively hingedly connected to the two sets of clamping assemblies 53. Through the above arrangement, the two sets of secondary synchronization mechanisms 524 are respectively connected to the four sets of clamping assemblies 53, thereby achieving the synchronous movement of the four sets of clamping assemblies 53 driven by the same clamping drive source 51.

[0038] like Figure 7 As shown, the upper mold locking member 30 of the present invention includes an upper mold locking portion 31 and an upper locking support portion 32, which are connected to each other. The upper locking support portion 32 is directly or indirectly connected to the upper mold plate 11. The upper mold locking portion 31 includes an upper locking end 311 and a first free end 312. The upper locking end 311 is disposed adjacent to the upper locking support portion 32 and is configured to fully engage with the mold locking mechanism 50 during full mold locking. The first free end 312 is the end closest to the lower mold locking member 40. Preferably, the upper mold locking portion 31 and the upper locking support portion 32 are cylindrical with different diameters, wherein the diameter of the upper mold locking portion 31 is larger than the diameter of the upper locking support portion 32.

[0039] The lower mold locking member 40 of the present invention includes a connected lower mold locking portion 41 and a lower locking support portion 42. The lower locking support portion 42 is directly or indirectly connected to the lower mold plate 21. The lower mold locking portion 41 includes a lower locking end 411 and a second free end 412. The lower locking end 411 is disposed adjacent to the lower locking support portion 42 and is configured to fully engage with the mold locking mechanism 50 during full mold locking. The second free end 412 is the end closest to the upper mold locking member 30. Preferably, the lower mold locking portion 41 and the lower locking support portion 42 are cylindrical in shape with different diameters, with the diameter of the lower mold locking portion 41 being larger than the diameter of the lower locking support portion 42.

[0040] When the upper mold locking member 30 and the lower mold locking member 40 reach the initial mold closing position, a first distance L1 is defined between the upper mold locking member 30 and the lower mold locking member 40, i.e., a first distance L1 is defined between the second free end 412 and the first free end 312. During the complete mold locking process, when the pressure unit 22 applies pressure to push the upper mold 12 and the lower mold 24 upward as a whole, i.e., the upper mold locking member 30 moves upward, causing the upper locking end 311 to contact the mold locking mechanism, driving the mold locking mechanism 50 upward, so that the mold locking mechanism 50 is fully engaged with the lower mold locking portion 41 of the lower mold locking member to achieve mold locking. At this time, a second distance L2 is defined between the upper mold locking member 30 and the lower mold locking member 40.

[0041] like Figures 4 to 6 As shown, specifically, the clamping assembly 53 includes a clamping shaft 531 rotatably provided on the lower mold plate 21 through a bearing member, and also includes a clamping member 532 movably provided on the clamping shaft 531, wherein the clamping member 532 can move up and down along the clamping shaft 531, and when the clamping shaft 531 rotates, the clamping member 532 can be driven to rotate around the clamping shaft 531 as the center. Figure 10 The open position W1 shown by the dotted line is rotated to the closed position W2 shown by the solid line, thereby locking the mold.

[0042] The mold clamping assembly 53 further includes a rotation auxiliary shaft 533 movably disposed within the mold clamping member 532, and a connecting member 534 fixedly disposed on the rotation auxiliary shaft 533 and the mold clamping shaft 531, wherein the rotation auxiliary shaft 533 and the mold clamping shaft 531 are disposed in parallel and on the same side of the connecting member 534. The rotation auxiliary shaft 533 and the mold clamping shaft 531 are configured as a whole via the connecting member 534. When the mold clamping drive source 51 drives the mold clamping shaft 531 to rotate, the rotation auxiliary shaft 533 and the mold clamping shaft 531 rotate as a whole, thereby driving the mold clamping member 532, which is respectively mounted on the rotation auxiliary shaft 533 and the mold clamping shaft 531, to rotate about the mold clamping shaft 531. Through the above-mentioned arrangement, the mold locking member 532 is rotated, thereby performing preliminary mold closing on the upper mold locking member 30 and the lower mold locking member 40 that have reached the preliminary mold closing position; and the mold locking member 532 is moved up and down. When the pressurizing unit 22 provides pressure, the mold locking member 532 can be driven to move upward and fully fit with the lower mold locking member 40.

[0043] Preferably, the mold clamping assembly 53 further includes an elastic element 535 for vertically resetting the mold clamping member 532. The elastic element 535 is mounted on the auxiliary rotation shaft 533 or the side of the mold clamping shaft 531 near the connecting member 534. The accompanying drawings only illustrate the elastic element 535 mounted on the side of the auxiliary rotation shaft 533 near the connecting member 534. After the mold clamping mechanism 50 fully clamps the upper mold locking member 30 and the lower mold locking member 40 and completes the tire vulcanization operation, the pressurizing unit 22 no longer provides upward pressure, and the mold clamping member 532, no longer subjected to the upward force, returns to its initial height due to the elastic restoring force of the elastic element 535.

[0044] like Figure 6 As shown, the locking component 532 described in the present invention has a locking space 5321, and the locking space 5321 has a first locking end 53211 and a second locking end 53212 respectively arranged at both ends in a third direction (such as the Z-axis direction). The first locking end 53211 is used to fit with the upper locking end 311 of the upper mold locking component during the locking process, and the second locking end 53212 is used to fit with the lower locking end 411 of the lower mold locking component during the locking process.

[0045] Preferably, the locking component 532 also includes a U-shaped groove 5322 that is set through. Through the setting of the U-shaped groove 5322, when the locking component 532 is rotated from the open position W1 to the closed position W2, the upper mold locking component 30 and the lower mold locking component 40 can be placed in the U-shaped groove 5322, so that the first locking end 53211 and the upper locking end 311 can fit over a larger range, and the second locking end 53212 and the lower locking end 411 can fit over a larger range, thereby making the locking component 532 more secure in locking the upper mold locking component 30 and the lower mold locking component 40.

[0046] The clamping shaft 531 has a first supporting end 5311 , and the clamping member 532 is rotatably disposed on the first supporting end 5311 of the clamping shaft, and the clamping member 532 is supported by the first supporting end 5311 .

[0047] The mold locking shaft 531 further comprises a second support end 5312, and the mold locking assembly 53 further comprises a support seat 536, which is fixedly disposed at the second support end 5312. The mold locking assembly 53 is rotatably disposed at the first bearing member 5371 and the second bearing member 5372. Figure 2 In the first setting hole 211 of the lower template 21, a first bearing member 5371 and a second bearing member 5372 are respectively disposed at both ends of the first setting hole 211. The first support end 5311 is disposed on the first setting hole 211 via the first bearing member 5371, and the second bearing member 5372 is disposed on the support seat 536. This arrangement allows the clamping shaft 531 to be rotatably disposed in the first setting hole 211 of the lower template.

[0048] Furthermore, to ensure that the upper mold locking member 30 and the lower mold locking member 40 are in the preliminary mold closing position when the mold locking mechanism 50 is used to lock the upper mold locking member 30 and the lower mold locking member 40, the vulcanizer according to the present invention further includes a detection mechanism 60 for detecting whether the upper mold locking member 30 and the lower mold locking member 40 are in the preliminary mold closing position. The detection mechanism 60 can be provided on one side of the upper mold locking member 30 or on one side of the lower mold locking member 40. The following description only assumes that the detection mechanism 60 is provided on one side of the lower mold locking member 40.

[0049] like Figure 8 and 9As shown, specifically, the detection mechanism 60 includes a detection shaft 61 movably arranged in the lower mold locking member and a limit end 62 fixedly arranged at the middle position of the detection shaft (the middle position described in the present invention refers to a certain length position in the middle of the detection shaft 61). The detection shaft 61 and the limit end 62 can be set as one piece or separately. The lower mold locking member 40 is provided with a second setting hole 431 and a third setting hole 432 that are coaxial and continuously arranged. The inner diameter of the third setting hole 432 is larger than the inner diameter of the second setting hole 431. The detection shaft 61 is set in the second setting hole 431 and the third setting hole 432. , and the two ends of the detection shaft 61 respectively protrude from the two ends of the lower mold locking member 40, that is, they respectively protrude from the second setting hole 431 and the third setting hole 432. The limiting end 62 is set in the third setting hole 432, and also includes a second elastic element 63 set in the third setting hole 432. The second elastic element 63 is sleeved on the detection shaft 61, and a spring support member 65 fixedly set on the end of the lower mold locking member 40. The spring support member 65 is set at one end of the lower mold locking member 40 close to the third setting hole 432, and the second elastic element 63 is set between the limiting end 62 and the spring support member 65. When the upper mold locking part 30 moves down to a certain distance, it will first contact the detection shaft 61 and press the detection shaft 61 downward, so that the second elastic element 63 is compressed. As the upper mold locking part 30 moves down, the distance that the detection shaft 61 moves down will also change synchronously. Therefore, the distance between the upper mold locking part 30 and the lower mold locking part 40 can be detected by detecting the position change of the detection shaft 61 to confirm whether the upper mold locking part 30 and the lower mold locking part 40 have reached the initial mold closing position.

[0050] Preferably, a detection assembly 64 is further included for detecting position changes of the detection shaft 61. The detection assembly 64 includes a fixed plate 641 fixedly provided on the lower mold plate 21, a detection element 642 provided on the fixed plate 641, and a trigger element 643 fixedly provided on the detection shaft 61. When the detection shaft 61 moves downward, the position of the trigger element 643 on the detection shaft 61 will change, until the upper mold locking member 30 moves downward to a specified position, driving the detection shaft 61 downward and driving the trigger element 643 on the detection shaft 61 to move to the detection element 642 to be detected. The detection element 642 feeds back this information to the control system, thereby controlling the mold locking drive source 51 in the mold locking mechanism 50 to drive the plurality of mold locking assemblies 53 to perform preliminary mold locking on the upper mold locking member 30 and the lower mold locking member 40.

[0051] like Figures 10 to 15As shown, the present invention also provides a clamping method for clamping the upper mold and the lower mold after mold closing: when the upper mold 12 and the lower mold 24 are clamped, the upper mold locking member 30 and the lower mold locking member 40 are driven to the preliminary mold closing position, and the upper mold locking member 30 and the lower mold locking member 40 are initially clamped by rotating the clamping member 532 in the clamping mechanism 50; when the pressure unit 22 applies pressure, the clamping member 532 moves up and down to perform a complete clamping step. The above method and steps completely lock the upper mold 12 and the lower mold 24, so that the upper mold 12 and the lower mold 24 will not move during the tire vulcanization process.

[0052] like Figures 10 to 13 As shown, the preliminary clamping step is that the clamping drive source 51 drives the clamping assembly 53 to rotate from the open position W1 to the closed position W2, so that the upper mold locking part 31 of the upper mold locking part and the lower mold locking part 41 of the lower mold locking part are placed in the clamping space 5321 of the clamping part 532.

[0053] During the initial mold clamping step, when the upper mold locking portion 31 and the lower mold locking portion 41 are within the mold clamping space 5321, the distance between the upper locking end 311 and the first mold clamping end 53211 of the mold clamping member is a third distance X1, the distance between the lower locking end 411 and the second mold clamping end 53212 of the mold clamping member is a fourth distance X2, and the distance between the second free end 412 and the first free end 312 is a first distance L1. Preferably, when the first distance L1, the third distance X1, and the fourth distance X2 are all between 2 and 5 mm, the mold clamping assembly 53 achieves optimal clamping effect on the upper mold locking member 30 and the lower mold locking member 40.

[0054] like Figure 14 and 15 As shown, the complete mold locking step is that the pressurizing unit 22 provides pressure to push the upper mold 12 and the lower mold 24 upward as a whole, driving the upper mold locking member 30 connected to the upper mold 12 to move upward, as shown in FIG. Figure 14 As shown, when the upper locking end 311 of the upper mold locking member 30 contacts the first locking end 53211 of the mold locking member, the mold locking member 532 is driven to move upward, as shown in FIG. Figure 15 As shown, the second clamping end 53212 of the clamping member is completely fitted with the lower clamping end 411 of the lower mold clamping member to achieve complete clamping.

[0055] When fully locked, the upper locking end 311 is fully fitted with the first locking end 53211 of the locking component, the lower locking end 411 is fully fitted with the second locking end 53212 of the locking component, and the second free end 412 and the first free end 312 have a second distance L2, where L2=L1+X1+X2.

[0056] Preferably, before the preliminary mold locking step, a preliminary mold closing position detection and judgment step is performed. When the system detects and determines that the upper mold locking member 30 and the lower mold locking member 40 have reached the preliminary mold closing position, the preliminary mold locking step is performed. The preliminary mold closing position detection and judgment step is as follows: the upper mold 12 is pressed downward to drive the upper mold locking member 30 downward. The upper mold locking member 30 contacts and presses down the detection shaft 61 provided on the protruding lower mold locking member 40. When the detection shaft 61 reaches the detection position, the system determines that the upper mold locking member 30 and the lower mold locking member 40 have reached the preliminary mold closing position.

[0057] The present invention mainly locks the upper mold locking member and the lower mold locking member that are relatively arranged by setting a locking mechanism, thereby completely fixing the positions of the upper mold and the lower mold, and preventing the upper mold and the lower mold from moving during the tire vulcanization process; the upper mold locking member with the upper mold locking part and the lower mold locking member with the lower mold locking part are locked by the locking mechanism, so that the structure of the upper mold locking member and the lower mold locking member is simpler; by setting a locking member that can rotate between an open position and a closed position, the upper mold locking member and the lower mold locking member are initially locked by a swinging manner; by setting The clamping member has a clamping space, so that when the upper mold locking member and the lower mold locking member are placed in the clamping space, there is a gap between the first clamping end and the second clamping end. When the pressure unit drives the upper mold locking member and the clamping member to move, the first clamping end can be in contact with the upper clamping end, and the second clamping end can be in contact with the lower clamping end, thereby achieving complete clamping of the upper mold locking member and the lower mold locking member. The clamping drive source drives the multiple clamping assemblies to move synchronously through a synchronous transmission mechanism, achieving the simultaneous movement of multiple clamping assemblies driven by the same drive source, which has the advantages of better synchronization and lower cost. The clamping mechanism of the present invention has the beneficial effects of simple structure and easy use.
