Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to an interchangeable solid tire mold. Background Technology
[0002] Traditional solid tire molds have significant limitations in practical use: the cavity and mold body are fixedly connected or have complex assembly structures. When changing to different specifications of cavities, multiple fixed parts need to be disassembled with special tools, which is cumbersome and time-consuming, seriously affecting production efficiency. In addition, a single mold is usually only suitable for one type of cavity. When producing solid tires of multiple specifications, multiple complete molds are required, which not only increases the cost of equipment procurement and storage, but also increases the difficulty of mold maintenance, making it difficult to meet the flexible production needs of small batches and multiple specifications. Utility Model Content

[0006] The limiting assembly includes a limiting plate, a top roller mounted on the top outer wall of the limiting plate, and a guide groove formed on the bottom outer wall of the limiting plate.
[0007] The transmission assembly includes a driving synchronous pulley mounted at the bottom of the rotating shaft, a driven synchronous pulley mounted at the bottom of the threaded rod, and a synchronous belt that drives the driving synchronous pulley and the driven synchronous pulley.
[0008] A rotating handle is installed on the top of the shaft, and a limit bolt is screwed onto one end of the bottom outer wall of the mounting plate.
[0009] The sleeve has fixed openings on both sides of its outer wall and sliding openings on the other two sides of its outer wall. The lifting block is slidably connected to the inner wall of the two sliding openings.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model discloses an interchangeable solid tire mold that allows for convenient fixing and replacement of the cavity.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-6 This utility model provides an interchangeable solid tire mold, comprising: a mold body 1 and a cavity 2 disposed within the mold body 1, and further comprising: a sleeve 3 installed on the bottom inner wall of the mold body 1, a threaded rod 4 rotatably installed on the bottom inner wall of the mold body 1, and two guide rods 5 installed on the bottom inner wall of the mold body 1, a lifting block 6 slidably connected to the outer wall of the sleeve 3, and a lifting assembly 7 screwed onto the threaded rod 4, guide plates 8 installed at both ends of the bottom inner wall of the mold body 1, and limit assemblies 9 slidably connected to both guide plates 8, the lifting assembly 7 being rotatably connected to the two limit assemblies 9 at both ends, an installation plate 11 installed on one side outer wall of the mold body 1, a rotating shaft 12 rotatably installed on the top outer wall of the installation plate 11, and a transmission assembly 13 installed at the bottom of the rotating shaft 12, the rotating shaft 12 being connected to the threaded rod 4 via the transmission assembly 13, and limit frames 16 installed at both ends of the bottom outer wall of the cavity 2.
[0021] It should be noted here that:
[0022] Initial placement of the cavity: The cavity 2 can be placed on the lifting block 6 inside the mold body 1. The lifting block 6 provides initial support for the cavity 2, ensuring that the cavity 2 is initially positioned in the preset position inside the mold body (1).
[0023] Cavity fixing transmission start: Rotate the rotating shaft 12, and the rotating shaft 12 transmits power to the threaded rod 4 through the transmission component 13, causing the threaded rod 4 to rotate on the inner wall of the bottom of the mold body 1; Since the lifting component 7 is screwed to the threaded rod 4, and the two guide rods 5 on the inner wall of the bottom of the mold body 1 guide the lifting component 7, the rotation of the threaded rod 4 will cause the lifting component 7 to descend along the direction of the guide rods 5.
[0024] The limiting components are linked to fix the cavity: the two ends of the lifting component 7 are rotatably connected to the two limiting components 9. When the lifting component 7 descends, it will pull the two limiting components 9 away from each other on the guide plate 8. When the two limiting components 9 are respectively inserted into the two limiting frames 16 at the bottom of the cavity 2, the cavity 2 is limited and fixed in the mold body 1, completing the installation and fixing of the cavity 2, and meeting the subsequent injection molding vulcanization requirements.
[0025] Cavity replacement unlocking: When it is necessary to replace cavity 2, rotate the threaded rod 4 in the opposite direction. The threaded rod 4 drives the lifting component 7 to rise along the guide rod 5. The rise of the lifting component 7 will push the two limit components 9 to move closer to each other on the guide plate 8, so that the two limit components 9 are pulled out from the two limit frames 16 respectively, releasing the fixed constraint on cavity 2.
[0026] Cavity ejection and dual mold body cooperation: As the two limiting components 9 approach each other, their tops will contact the bottom of the lifting block 6 and generate an upward pushing force on the lifting block 6; the lifting block 6 slides up along the outer wall of the sleeve 3, thereby driving the cavity 2 to rise synchronously, making it convenient for the operator to remove the cavity 2 from the mold body 1; in actual use, cavities 2 of different specifications can be installed in the two mold bodies 1 respectively, serving as the upper mold and the lower mold, to cooperate in completing the mold injection operation.
[0027] In a preferred embodiment, the lifting assembly 7 includes a strip block 701, a threaded through hole 702 opened in the middle of the top outer wall of the strip block 701, guide holes 703 opened at both ends of the top outer wall of the strip block 701, and traction rods 704 rotatably mounted on the outer walls of both sides of the strip block 701.
[0028] It should be noted here that:
[0029] Power transmission and lifting guidance: The threaded through hole 702 in the middle of the top outer wall of the strip block 701 is screwed to the threaded rod 4. When the threaded rod 4 rotates, it drives the strip block 701 to rise and fall through the thread engagement. At the same time, the guide holes 703 at both ends of the top outer wall of the strip block 701 are sleeved on the guide rod 5. The sliding fit between the guide hole 703 and the guide rod 5 restricts the lifting direction of the strip block 701, prevents it from deviating as the threaded rod 4 rotates, and ensures smooth lifting action.
[0030] The traction and limiting components are linked: the traction rods 704 are rotatably mounted on the outer walls of both sides of the strip block 701, and their other ends are rotatably connected to the limiting components 9; when the strip block 701 descends, the traction rods 704 will spread out to both sides, pulling the two limiting components 9 away from each other along the guide plate 8; when the strip block 701 rises, the traction rods 704 will retract towards the middle, pushing the two limiting components 9 closer to each other along the guide plate 8, realizing the mechanical linkage of "lifting component lifting - limiting component moving".
[0031] In a preferred embodiment, the limiting component 9 includes a limiting plate 901, a top roller 902 mounted on the top outer wall of the limiting plate 901, and a guide groove 903 formed on the bottom outer wall of the limiting plate 901.
[0032] It should be noted here that:
[0033] Smooth movement guidance: The guide groove 903 on the bottom outer wall of the limiting plate 901 is slidably connected to the guide plate 8 at the bottom of the mold body 1. The guide groove 903 follows the sliding trajectory of the guide plate 8 to ensure that the limiting plate 901 will not deviate when it approaches / moves away from the cavity 2, thus ensuring accurate movement path.
[0034] Cavity fixing: When the lifting assembly 7 moves the limiting plate 901 away from each other, the main body of the limiting plate 901 will be inserted into the limiting frame 16 at the bottom of the cavity 2. Through the engagement of the limiting plate 901 and the limiting frame 16, the displacement of the cavity 2 in the mold body 1 is restricted, thereby fixing the cavity 2.
[0035] Cavity ejection: When the lifting assembly 7 drives the limiting plates 901 to approach each other, the top roller 902 on the top of the limiting plate 901 will first contact the bottom of the lifting block 6; as the limiting plate 901 continues to approach, the top roller 902 generates an upward pushing force on the lifting block 6, and the top roller 902 can roll, which can reduce the frictional resistance between it and the lifting block 6, so that the lifting block 6 rises smoothly and drives the cavity 2 to rise synchronously, making it easy to remove the cavity 2.
[0036] In a preferred embodiment, the transmission assembly 13 includes a driving synchronous pulley 1301 mounted on the bottom of the rotating shaft 12, a driven synchronous pulley 1302 mounted on the bottom of the threaded rod 4, and a synchronous belt 1303 that drives the driving synchronous pulley 1301 and the driven synchronous pulley 1302.
[0037] It should be noted here that:
[0038] Power input and transmission: When the operator rotates the shaft 12, the driving synchronous pulley 1301 at the bottom of the shaft 12 rotates synchronously with the shaft 12; the driving synchronous pulley 1301 forms a transmission connection with the driven synchronous pulley 1302 at the bottom of the threaded rod 4 through the synchronous belt 1303, and the rotational power of the driving synchronous pulley 1301 is transmitted to the driven synchronous pulley 1302 through the synchronous belt 1303.
[0039] Driven by the rotation of the threaded rod: The driven synchronous pulley 1302 is fixedly connected to the threaded rod 4. When the driven synchronous pulley 1302 rotates, it will directly drive the threaded rod 4 to rotate on the inner wall of the bottom of the mold body 1. The transmission method of the synchronous belt 1303 can ensure that the speed of the active synchronous pulley 1301 and the driven synchronous pulley 1302 is synchronized, avoiding slippage or speed deviation during power transmission, ensuring that the threaded rod 4 rotates smoothly, and thus ensuring the precise action of the subsequent lifting assembly 7 and the limiting assembly 9.
[0040] In a preferred embodiment, a rotating handle is mounted on the top of the rotating shaft 12, and a limit bolt 15 is screwed onto one end of the bottom outer wall of the mounting plate 11.
[0041] It should be noted here that:
[0042] Convenient power input: The rotating handle on the top of the rotating shaft 12 increases the contact area for the operator to apply force. The operator can drive the rotating shaft 12 to rotate more effortlessly by rotating the handle, reducing the difficulty of operation and improving the efficiency of cavity fixing or unlocking.
[0043] Rotary shaft limiting and fixing: When the rotating shaft 12 rotates to the preset position (i.e., the limiting component 9 is inserted into the limiting frame 16 to complete the cavity fixing, or the limiting component 9 is pulled out to complete the cavity unlocking), the limiting bolt 15 at the bottom of the mounting plate 11 can be turned so that the top of the limiting bolt 15 presses against the outer wall of the rotating handle of the rotating shaft 12, limiting the accidental rotation of the rotating shaft 12, and preventing the limiting component 9 from loosening due to the accidental rotation of the threaded rod 4 during the injection or vulcanization process of the mold, thereby ensuring the fixed stability of the cavity 2 in the mold body 1.
[0044] In a preferred embodiment, the outer walls of both sides of the sleeve 3 are provided with fixing openings 14, and the outer walls of the other two sides of the sleeve 3 are provided with sliding openings 10. The lifting block 6 is slidably connected to the inner walls of the two sliding openings 10.
[0045] It should be noted here that: the fixed port 14 provides the movement space for the traction rod 704, and the sliding port 10 and the lifting block 6 slide together to ensure that the lifting block 6 drives the cavity 2 to rise and be taken out or to fall and be placed smoothly.
[0046] Working principle:
[0047] Initial placement of the cavity: Place the cavity 2 on the lifting block 6 inside the mold body 1. The lifting block 6 provides initial support for the cavity 2, ensuring that the cavity 2 is initially in the preset installation position inside the mold body 1.
[0048] Power input and transmission: The operator rotates the handle at the top of the rotating shaft 12, causing the rotating shaft 12 to rotate on the outer wall of the top of the mounting plate 11. The transmission assembly 13 at the bottom of the rotating shaft 12 starts to work, in which the driving synchronous pulley 1301 rotates synchronously with the rotating shaft 12, and transmits power to the driven synchronous pulley 1302 at the bottom of the threaded rod 4 through the synchronous belt 1303, thereby driving the threaded rod 4 to rotate on the inner wall of the bottom of the mold body 1.
[0049] The lifting assembly drives the limiting assembly to move (cavity fixed): When the threaded rod 4 rotates, the lifting assembly 7 (including strip block 701, threaded through hole 702, guide hole 703, and traction rod 704) connected to the threaded rod 4 descends vertically under the guidance of two guide rods 5 on the inner wall of the bottom of the mold body 1 (guide hole 703 slides along guide rod 5). The traction rods 704 on both sides of the lifting assembly 7 then pull the two limiting assemblies 9 (including limiting plate 901, top roller 902, and guide groove 903), causing the limiting assemblies 9 to move away from each other along the guide plate 8 at the bottom of the mold body 1 (guide groove 903 slides with guide plate 8). When the two limiting assemblies 9 are respectively inserted into the two limiting brackets 16 at the bottom of the cavity 2, the cavity 2 is fixed inside the mold body 1. At this time, the limiting bolt 15 at the bottom of the mounting plate 11 can be tightened so that its top end presses against the rotation handle at the top of the rotating shaft 12, limiting the accidental rotation of the rotating shaft 12 and ensuring the cavity 2 is fixed and stable.
[0050] The lifting assembly drives the movement of the limiting assembly (cavity unlocking and ejection): When it is necessary to replace cavity 2, first loosen the limiting bolt 15 to release the restriction on the rotating shaft 12, then rotate the rotating shaft 12 in the opposite direction, which drives the threaded rod 4 to rotate in the opposite direction through the transmission assembly 13. The reverse rotation of the threaded rod 4 causes the lifting assembly 7 to rise along the guide rod 5, and the traction rod 704 pushes the two limiting assemblies 9 closer to each other along the guide plate 8. The limiting assemblies 9 are pulled out from the limiting frame 16, releasing the fixation on cavity 2. As the limiting assemblies 9 continue to approach each other, the top roller 902 of its top contacts the bottom of the lifting block 6 and pushes the lifting block 6 upward. The lifting block 6 slides upward along the inner wall of the sliding port 10 on the outer wall of the sleeve 3, driving the cavity 2 to rise, making it convenient for the operator to remove the cavity 2 from the mold body 1.
[0051] Dual-mold injection molding: In actual use, cavities 2 of different specifications can be installed in two mold bodies 1 respectively, and the two mold bodies 1 can be used as the upper mold and the lower mold respectively to complete the mold injection operation.
[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
