Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, specifically to a mold side plate and tire mold with quick-change type blocks. Background Technology

[0002] Tire molds are the core equipment for tire vulcanization molding. The mold sideplate, as a key component in tire sidewall molding, directly determines the appearance precision and molding quality of the sidewall. To accommodate the curved contour of the tire sidewall, the upper surface of the mold sideplate is typically designed as a downward-curved arc structure, and movable blocks must be installed at predetermined positions on the sideplate. The upper surface of the movable blocks must maintain a continuous and smooth transition with the curved surface of the sideplate to ensure that the brand logo, specification numbers, certification symbols, and other information on the vulcanized tire sidewall are clear and complete, without any protrusions or dents.

[0003] Currently, to secure the type blocks, internally threaded holes distributed along the thickness direction are pre-set on the side of the type block away from the forming surface. Correspondingly, a type groove adapted to the shape of the type block is machined on the side plate of the mold, and a countersunk hole extending through to the type groove is opened on the side plate body at the position corresponding to the internally threaded hole. During assembly, the type block is embedded into the type groove and its bottom surface is made to fit tightly against the bottom of the groove. Then, the bolt is passed through the countersunk hole and screwed into the internally threaded hole of the type block for tightening. The rigid fixation of the type block is achieved by the axial preload of the bolt.

[0004] However, when it is necessary to replace the movable type blocks, the operator must first disassemble and remove the entire mold from the vulcanization molding equipment, then use hoisting equipment to lift the mold side plate and flip it so that the back faces outward (exposing the bolt connection parts), and then loosen and remove the fixing bolts one by one to take out the old movable type blocks. Due to the space requirements for mold hoisting and flipping, it is difficult to achieve rapid replacement of movable type blocks. To address this, we propose a mold side plate and tire mold that can quickly replace movable type blocks to effectively solve the above-mentioned drawbacks. Summary of the Invention

[0019] When the movable type block body is assembled and fixed in the movable type slot, the fixing part fits against the wall of the arc-shaped slot.

[0020] Optionally, a pad is detachably connected inside the operation box; when the fixing member is in the locked position, the pad is located in the area between the front of the swing block and the operation box; when the fixing member is in the unlocked position, the pad is located in the area between the rear of the swing block and the operation box.

[0021] Optionally, the rotating mechanism includes a vertical shaft rotatably connected to the operation box, the vertical shaft extending in a vertical direction, and the fixing member fixed to the side wall of the vertical shaft;

Moreover, the upward movement distance is greater than the previous downward movement distance, so that the upper end of the movable type block body can be detached from the movable type slot, which greatly improves the convenience of removing the movable type block body.

Detailed Implementation

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1: Please refer to Figures 1 to 7 A mold side plate with quick-change type blocks includes a side plate body 1 and a type block body 2. The top surface of the side plate body 1 is an arc-shaped structure adapted to the profile of the tire sidewall.

[0057] This embodiment also includes: movable type slot 3, elastic ejection mechanism 4, fixing slot 5, operation box 6, fixing component 7, and rotating mechanism 8.

[0058] The movable type groove 3 is located on the top surface of the side plate body 1 and is adapted to the movable type block body 2 for mounting the movable type block body 2. When the movable type block body 2 is assembled and fixed in the movable type groove 3, the top surface of the movable type block body 2 is coplanar with the top surface of the side plate body 1, which avoids bulges or depressions on the tire sidewall during vulcanization and ensures the clarity of the brand logo, specification numbers, and certification symbols.

[0059] Secondly, the elastic ejection mechanism 4 is embedded in the bottom of the type slot 3, and the top of the elastic ejection mechanism 4 abuts against the bottom surface of the type block body 2. In this embodiment, the elastic ejection mechanism 4 can be an ejection spring (the number of which can be adjusted according to the size of the type block body 2). A flat-bottomed hole adapted to the ejection spring is opened in the bottom of the type slot 3, and the lower end of the ejection spring is located in the flat-bottomed hole. Under normal conditions, the ejection spring extends vertically. When the type block body 2 is unlocked, the ejection spring releases its elastic potential energy, generating a pushing force of 80-100N in the vertical direction, which can lift the type block body 2 upward, so that the top surface of the type block body 2 is exposed outside the type slot 3, thereby facilitating the removal of the type block body 2.

[0060] Additionally, a fixing groove 5 is formed on the side wall of the middle part of the movable type block body 2, cooperating with the fixing member 7 to lock the movable type block body 2. An operating box 6 is embedded in the top of the side plate body 1 and communicates with the middle of the movable type groove 3. The top surface of the operating box 6 is coplanar with the top surface of the side plate body 1 to avoid affecting the tire sidewall molding. The fixing member 7 is movably disposed within the operating box 6 and adapted to the fixing groove 5. When the fixing member 7 enters the fixing groove 5, its bottom surface abuts against the bottom of the groove, thereby restricting the vertical movement of the movable type block body 2 and achieving rigid locking of the movable type block body 2 within the movable type groove 3.

[0061] In this embodiment, the upper end of the operation box 6 is open, and a cover 9 is detachably connected to the upper end of the operation box 6. The top surface of the cover 9 is coplanar with the top surface of the operation box 6. It should be noted that the cover 9 is detachably connected to the operation box 6 by magnetic attraction. Under normal conditions, the cover 9 is closed by magnetic attraction to prevent rubber debris from entering the operation box 6 during vulcanization. When operation is required, an external magnetic force of 50-60N is applied to remove the cover 9, exposing the internal components for driving the rotating mechanism 8.

[0062] Finally, the rotating mechanism 8 is located inside the operating box 6 and connected to the fixing member 7, which is used to drive the fixing member 7 to rotate into or out of the fixing groove 5, thereby realizing the locking and unlocking of the movable type block body 2.

[0063] With the above design, through the cooperation of the fixing groove 5, the fixing part 7 and the rotating mechanism 8, there is no need to disassemble or flip the side plate body 1 or the whole mold. The time for a single replacement is shortened from 2-4 hours in the traditional bolt connection method to 3-5 minutes, and the efficiency is improved by more than 85%.

[0064] The rotating mechanism 8 in this embodiment is described below:

[0065] The rotating mechanism 8 includes a support 801 fixed to the bottom of the operating box 6. A longitudinal shaft 802 extending horizontally is fixed on the support 801, and the fixing member 7 is rotatably connected to the longitudinal shaft 802. It should be noted that, to prevent the fixing member 7 from accidentally rotating and unlocking along the longitudinal shaft 802 due to mold vibration during vulcanization, a limiting baffle 17 is movably installed inside the operating box 6 above the support 801. Horizontal guide grooves 18 are correspondingly formed on the inner walls of the front and rear sides of the operating box 6. The two ends of the limiting baffle 17 are embedded in the horizontal guide grooves 18, allowing it to slide horizontally above the support 801 along the horizontal guide grooves 18. When the fixing member 7 rotates counterclockwise around the longitudinal shaft 802 until it is fully inserted into the fixing groove 5 (at which point there is no gap between the contact surfaces of the fixing member 7 and the fixing groove 5), the limiting baffle 17 is manually pushed to slide along the horizontal guide groove 18 to directly above the support 801. The bottom surface of the limiting baffle 17 is tightly fitted with the top surface of the fixing member 7, mechanically blocking the rotation path of the fixing member 7. When unlocking, simply slide the limiting baffle in the opposite direction to disengage it from the fixing member 7 to restore the rotational freedom of the fixing member 7. In addition, a blocking block 19 is bolted into the operation box 6. The blocking block 19 can be inserted into the groove of the limiting baffle 17 on the side away from the fixing groove 5 to prevent the limiting baffle 17 from moving away from the fixing groove 5, thus avoiding accidental rotation and unlocking of the fixing member 7 due to mold vibration during vulcanization.

[0066] When the movable type block body 2 is assembled and fixed in the movable type groove 3, the fixing part 7 is in contact with the bottom of the groove 5, and the bottom surface of the movable type block body 2 is in contact with the bottom of the groove 3, so that the movable type block body 2 cannot move vertically, thus ensuring the tire sidewall forming accuracy.

[0067] When unlocking is required, first apply external force to remove the magnetically connected cover 9 at the top of the operation box 6, exposing the internal components of the operation box 6. Then, slide the limiting baffle 17 inside the operation box 6 to move it away from directly above the support 801, releasing the rotation restriction on the fixing member 7. Next, rotate the fixing member 7 in the opposite direction around the longitudinal axis 802, causing the fixing member 7 to gradually exit the fixing groove 5 on the side wall of the movable type body 2, releasing the vertical lock on the movable type body 2. As the fixing member 7 completely disengages from the fixing groove 5, the pre-compressed elastic ejection mechanism 4 at the bottom of the movable type groove 3 releases its elastic force, pushing the movable type body 2 upward, causing the bottom surface of the movable type body 2 to disengage from the bottom of the movable type groove 3 and pop upward a short distance (for subsequent removal), completing the unlocking process.

[0068] Example 2: Please refer to Figures 8 to 12 This embodiment also proposes a mold side plate that allows for quick replacement of movable type blocks. The difference between this embodiment and Embodiment 1 is that:

[0069] The rotating mechanism 8 includes a horizontal shaft 803 fixed inside the operating box 6 and extending horizontally. A swing block 804 is rotatably connected to the horizontal shaft 803, and a fixing member 7 is vertically fixed to the side wall of the swing block 804 facing the movable type slot 3. When the swing block 804 rotates around the horizontal shaft 803, it can drive the fixing member 7 to rotate synchronously to change its spatial position, thereby realizing the locking or unlocking switch of the movable type block body 2.

[0070] To enhance the locking stability of the fixing member 7, a pad 20 is detachably connected inside the operation box 6. When the fixing member 7 is in the locked position, the pad 20 is located in the area between the front of the swing block 804 and the operation box 6; when the fixing member 7 is in the unlocked position, the pad 20 is located in the area between the rear of the swing block 804 and the operation box 6. This mechanical limiting structure prevents the swing block 804 from rotating unexpectedly along the horizontal axis 803, ensuring the reliability of the locked or unlocked state. Additionally, the rotation of the swing block 804 can be controlled by inserting the pad 20 into the front or rear of the swing block 804.

[0071] In this embodiment, the lower end of the fixing groove 5 extends to the bottom surface of the movable type block body 2. When the movable type block body 2 is placed into the movable type groove 3 from top to bottom, the fixing member 7 can smoothly enter the inner cavity of the fixing groove 5 through the lower opening, avoiding interference during assembly. An arc-shaped groove 10 communicating with the fixing groove 5 is provided on the side wall of the movable type block body 2 (the arc trajectory is adapted to the rotation path of the fixing member 7). After the movable type block body 2 is placed in the movable type groove 3, the swing block 804 is rotated to rotate along the horizontal axis 803, and the fixing member 7 can smoothly rotate from the fixing groove 5 into the arc-shaped groove 10, completing the transition of the locking action.

[0072] When the movable type block body 2 is assembled and fixed in the movable type groove 3, the fixing part 7 fits against the groove wall of the arc groove 10. Through the vertical limiting effect of the arc groove 10, the vertical movement of the movable type block body 2 is restricted, thus achieving a stable lock.

[0073] Example 3: Please refer to Figures 13 to 22 This embodiment also proposes a mold side plate that allows for quick replacement of movable type blocks. The difference between this embodiment and Embodiments 1 and 2 is that:

[0074] The rotating mechanism 8 includes a vertical shaft 805 rotatably connected to the operation box 6. The vertical shaft 805 extends vertically, and the fixing member 7 is fixed to the side wall of the vertical shaft 805. When the movable type block body 2 is assembled and fixed in the movable type slot 3, the fixing member 7 is in contact with the top and bottom of the slot 5. Through this surface contact, the fixing member 7 can form a vertical limit on the movable type block body 2, preventing it from moving up and down along the depth direction of the movable type slot 3, and finally achieving a stable lock of the movable type block body 2 in the movable type slot 3.

[0075] During the research and development process, it was discovered that during tire vulcanization, some molten rubber easily seeps into the joint between the type block body 2 and the side plate body 1 and solidifies, causing them to adhere tightly. In this case, relying solely on the elastic force of the elastic ejection mechanism 4 is insufficient to overcome the adhesive resistance of the solidified rubber, affecting the replacement efficiency of the type block body 2. To solve this problem, the following design was developed:

[0076] The bottom left and right sides of the fastener 7 are provided with first inclined surfaces 11, and the bottom of the fixing groove 5 is movably embedded with first ball bearings 12. Through the rolling cooperation of the first inclined surfaces 11 and the first ball bearings 12, the frictional resistance when the fastener 7 enters or exits the fixing groove 5 can be effectively reduced, and the smoothness of operation can be improved.

[0077] As the fixing member 7 rotates out of the fixing groove 5 around the vertical axis 805, the movable type block body 2 moves downward through the cooperation of the first inclined surface 11 and the first ball bearing 12. Specifically, the first inclined surface 11 first contacts the protruding spherical surface of the first ball bearing 12. As the rotation continues, the inclined surface transmits downward pressure along the depth direction of the movable type groove 3 to the movable type block body 2 through the ball bearing. This pressure forces the movable type block body 2 to overcome the preload of the elastic ejection mechanism 4 and move downward slightly, thereby forming a shearing and peeling action on the cured rubber in the gap, destroying its adhesive structure.

[0078] It should be added that, to ensure the reliability of the locking of the fastener 7 to the movable type block body 2 and to prevent the fastener 7 from loosening due to vulcanization vibration, a shim 21 is also fixed to the top of the fixing groove 5. The installation position of the shim 21 is completely offset from the first ball bearing 12 (without spatial overlap) to avoid interfering with the movement of the ball bearing. When locking the movable type block body 2, after the fastener 7 rotates into the fixing groove 5, its top surface is tightly fitted with the shim 21 (forming a vertical upper limit limit), and its bottom surface is in direct contact with the bottom of the fixing groove 5 (forming a vertical lower limit limit), and the bottom surface of the fastener 7 does not contact the first ball bearing 12 (e.g., Figure 20 As shown in the figure, the "upper and lower bidirectional limiting" structural design achieves a stable vertical constraint on the movable type block body 2, ensuring that the movable type block has no displacement deviation during the vulcanization process.

[0079] It is worth mentioning that, in order to further ensure that the movable type block body 2 can be stably disengaged, a protrusion 13 is fixed on the side wall of the vertical shaft 805, and a second ball bearing 14 is movably embedded in the top of the protrusion 13. A vertical groove 15 adapted to the protrusion 13 is provided on the side wall of the movable type block body 2, the lower end of the vertical groove 15 extends to the bottom surface of the movable type block body 2, and a second inclined surface 16 is provided at the top of the vertical groove 15.

[0080] As the protrusion 13 rotates around the vertical axis 805 into the vertical groove 15, the second inclined surface 16 and the second ball bearing 14 work together to move the movable type block body 2 upward. Specifically, after the fixing member 7 exits the fixing groove 5, the vertical axis 805 continues to rotate, driving the protrusion 13 into the vertical groove 15. At this time, the second ball bearing 14 contacts the second inclined surface 16 and generates an upward pushing force, driving the movable type block body 2 to move upward along the depth direction of the movable type groove 3. The upward movement distance is greater than the previous downward slight movement distance, which not only completely cancels out the downward slight displacement, but also works in conjunction with the elastic force of the elastic ejection mechanism 4 to jointly drive the movable type block body 2 to completely detach from the movable type groove 3, achieving stable ejection.

[0081] In conventional methods, the upward force must simultaneously overcome the surface adhesion between the rubber and the type blocks and side plates, as well as the overall resistance of the cured rubber layer. This not only requires an extremely large pushing force but also easily leads to partial adhesion after localized rubber breakage, causing the type blocks to jam or insufficient ejection height, requiring manual prying. This design, however, utilizes the relative displacement between the type block sidewalls and the side plate gaps to generate a lateral shear force on the continuous rubber layer, directly severing the rubber's integrity. The subsequent upward movement only needs to overcome the local resistance of scattered rubber fragments, rather than the surface adhesion of the intact rubber layer. This reduces the breaking resistance by more than 60%, significantly improving the reliability and efficiency of the ejection process.

[0082] Example 4: This example also provides a tire mold, including a mold side plate as described in any of Examples 1 to 3. By using the mold side plate of any of the aforementioned examples, the tire mold ensures the molding accuracy of information such as tire sidewall brand markings and specification numbers after vulcanization, and can also adapt to the rapid changeover requirements of multi-specification products on the tire production line, thereby improving the overall operational reliability and economic efficiency of the mold.
