Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire manufacturing technology, in particular to a mold side plate capable of quickly replacing a movable block and a tire mold. BACKGROUND

[0002] The tire mold is the core equipment for tire vulcanization forming, and the mold side plate is a key component for forming the tire side. The structural design of the mold side plate directly determines the appearance precision and forming quality of the tire side. In order to adapt to the curved profile of the tire side, the upper surface of the mold side plate is usually designed as a downwardly concave curved structure, and a movable block is installed at a predetermined position of the side plate. The upper surface of the movable block needs to be smoothly connected with the curved surface of the side plate to ensure that the brand logo, specification number, certification symbol and other information on the tire side after vulcanization are clear and complete without protrusions or recesses. At present, in order to fix the movable block, an internal threaded hole is provided on the side of the movable block away from the forming surface and distributed along the thickness direction. Correspondingly, a movable slot is formed on the mold side plate and matched with the shape of the movable block, and a countersunk hole is formed in the side plate body corresponding to the position of the internal threaded hole and penetrating to the movable slot. During assembly, the movable block is embedded in the movable slot and the bottom surface of the movable block is tightly fitted with the bottom of the slot, and then the bolt is screwed and fastened with the internal threaded hole of the movable block through the countersunk hole, and the rigid fixation of the movable block is realized by the axial pre-tightening force of the bolt.

[0003] However, when the movable block needs to be replaced, the operator needs to first disassemble and remove the entire mold from the vulcanization forming equipment, then use hoisting equipment to lift and overturn the mold side plate with the back outward (so that the bolt connection part is exposed), and then loosen and remove the fixing bolts one by one to remove the old movable block. Due to the space requirements of mold hoisting and overturning, it is difficult to achieve quick replacement of the movable block. Therefore, we propose a mold side plate capable of quickly replacing a movable block and a tire mold to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0019] ​With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0020] Embodiment one: please refer to Figures 1 to 7 A mold side plate with replaceable type block, comprising a side plate body 1 and a type block body 2. The top surface of the side plate body 1 is arc-shaped structure suitable for the tire sidewall contour.

[0021] The embodiment also includes a type slot 3, an elastic ejection mechanism 4, a fixing slot 5, an operation box 6, a fixing piece 7 and a rotating mechanism 8.

[0022] The type slot 3 is arranged on the top surface of the side plate body 1 and is suitable for the type block body 2, for installing the type block body 2. When the type block body 2 is assembled and fixed in the type slot 3, the top surface of the type block body 2 is coplanar with the top surface of the side plate body 1, avoiding the tire sidewall from being convex or concave during vulcanization, and ensuring the molding clarity of brand logo, specification number and certification symbol.

[0023] Secondly, the elastic ejection mechanism 4 is embedded in the bottom of the type slot 3, and the top end 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 adopt an ejection spring (the number of which can be adjusted according to the size of the type block body 2), and a flat-bottom hole suitable for the ejection spring is arranged in the bottom of the type slot 3, and the lower end of the ejection spring is located in the flat-bottom hole. Under normal circumstances, the ejection spring extends in the vertical direction. When the type block body 2 is unlocked, the ejection spring releases the elastic potential energy and generates a 80-100N upward thrust 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.

[0024] In addition, the fixing slot 5 is arranged on the sidewall of the middle part of the type block body 2 and cooperates with the fixing piece 7 to realize the locking of the type block body 2. The operation box 6 is embedded in the top of the side plate body 1 and communicates with the middle part of the type slot 3, and the top surface of the operation box 6 is coplanar with the top surface of the side plate body 1, avoiding affecting the tire sidewall molding. The fixing piece 7 is movably arranged in the operation box 6 and is suitable for the fixing slot 5. When the fixing piece 7 enters the fixing slot 5, the bottom surface thereof abuts against the bottom of the slot, thereby limiting the vertical movement of the type block body 2 and realizing the rigid locking of the type block body 2 in the type slot 3.

[0025] In the present 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, and 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, and the cover 9 is closed by magnetic force in the normal state to prevent rubber debris from entering the operation box 6 during vulcanization; when operation is needed, the cover 9 can be removed by applying an external magnetic attraction force of 50-60 N to expose the internal components for driving the rotating mechanism 8.

[0026] Finally, the rotating mechanism 8 is arranged in the operation box 6 and connected with the fixing member 7, for driving the fixing member 7 to rotate into or out of the fixing groove 5, thereby realizing locking and unlocking of the type block body 2.

[0027] With the above design, through the cooperation of the fixing groove 5, the fixing member 7 and the rotating mechanism 8, without disassembling and turning over the side plate body 1 or the entire mold, the single replacement time is shortened from 2-4 hours in the traditional bolt connection mode to 3-5 minutes, and the efficiency is improved by more than 85%.

[0028] The rotating mechanism 8 in the present embodiment will be described below: The rotating mechanism 8 includes a support 801 fixed to the bottom of the operation box 6, and a longitudinal shaft 802 extending in the horizontal direction is fixed on the support 801, and the fixing member 7 is rotationally connected with the longitudinal shaft 802. It should be noted that, in order to avoid the fixing member 7 from being accidentally rotated and unlocked due to mold vibration during vulcanization, a limiting baffle 17 is movably arranged above the support 801 in the operation box 6, and horizontal guide sliding grooves 18 are formed in the inner walls of the front and rear sides of the operation box 6, and the two ends of the limiting baffle 17 are embedded in the horizontal guide sliding grooves 18 and can slide horizontally above the support 801 along the horizontal guide sliding grooves 18. When the fixing member 7 is rotated counterclockwise around the longitudinal shaft 802 to be completely inserted into the fixing groove 5 (at this time, there is no gap between the fixing member 7 and the fitting surface of the fixing groove 5), the limiting baffle 17 is manually pushed to slide along the horizontal guide sliding groove 18 to be directly above the support 801, and the bottom surface of the limiting baffle 17 is tightly fitted with the top surface of the fixing member 7, thereby blocking the rotation path of the fixing member 7 by mechanical limiting. When unlocking, the limiting baffle 17 only needs to be slid in the opposite direction to be separated from above the fixing member 7, so that the rotation freedom of the fixing member 7 can be restored. In addition, a blocking block 19 is connected by bolts in the operation box 6, and the blocking block 19 can be inserted into the groove on the side of the limiting baffle 17 away from the fixing groove 5, for preventing the limiting baffle 17 from moving away from the fixing groove 5, so as to avoid the fixing member 7 from being accidentally rotated and unlocked due to mold vibration during vulcanization.

[0029] When the type block body 2 is assembled and fixed in the type groove 3, the fixing member 7 is fitted with the groove bottom of the fixing groove 5, and the bottom surface of the type block body 2 is fitted with the groove bottom of the type groove 3, so that the type block body 2 cannot be vertically moved, thereby ensuring the tire side forming precision.

[0030] When it is necessary to unlock, the outer force is first applied to remove the cover 9 on the upper end of the operation box 6 through the magnetic attraction connection, and the internal components of the operation box 6 are exposed. Then, the limiting baffle 17 in the operation box 6 is slid to move away from the upper part of the support 801, and the rotation restriction of the fixing part 7 is released. Then, the fixing part 7 is reversely rotated around the longitudinal shaft 802, and the fixing part 7 gradually exits the fixing groove 5 of the side wall of the type block body 2, and the vertical locking of the type block body 2 is released. When the fixing part 7 completely leaves the fixing groove 5, the elastic ejection mechanism 4 at the bottom of the type block groove 3 is released, the elastic force is released, the type block body 2 is pushed upward, the bottom surface of the type block body 2 is separated from the groove bottom of the type block groove 3 and is bounced upward by a small distance (convenient for subsequent removal), and the unlocking is completed. Embodiment two: please refer to Figures 8 to 12 The embodiment also provides a mold side plate capable of quickly replacing the type block. The embodiment is different from the embodiment one in that: The rotating mechanism 8 comprises a horizontal shaft 803 fixed in the operation box 6 and extending in the horizontal direction, a swing block 804 rotationally connected to the horizontal shaft 803, and the fixing part 7 vertically fixed to the side wall of the swing block 804 facing the type block groove 3. When the swing block 804 rotates around the horizontal shaft 803, the fixing part 7 can be synchronously rotated to change the spatial position thereof, so that the locking or unlocking of the type block body 2 is switched.

[0031] In order to enhance the locking stability of the fixing part 7, the operation box 6 is detachably connected with a pad 20. When the fixing part 7 is in the locking position, the pad 20 is located at the region between the front part of the swing block 804 and the operation box 6. When the fixing part 7 is in the unlocking position, the pad 20 is located at the region between the rear part of the swing block 804 and the operation box 6. The pad 20 prevents the swing block 804 from being accidentally rotated along the horizontal shaft 803 through the mechanical limiting structure, and ensures the reliability of the locking or unlocking state. In addition, the rotation control of the swing block 804 can be realized by inserting the pad 20 into the front part or the rear part of the swing block 804.

[0032] In the embodiment, the lower end of the fixing groove 5 extends to the bottom surface of the type block body 2. When the type block body 2 is placed into the type block groove 3 from top to bottom, the fixing part 7 can smoothly enter the inner cavity of the fixing groove 5 through the lower end opening, so that the interference during assembly is avoided. An arc-shaped groove 10 (the arc-shaped track is matched with the rotation path of the fixing part 7) is formed in the side wall of the type block body 2 and communicated with the fixing groove 5. When the type block body 2 is placed into the type block groove 3 in place, the swing block 804 is rotated along the horizontal shaft 803, the fixing part 7 can be smoothly rotated from the fixing groove 5 into the arc-shaped groove 10, and the transition of the locking action is completed.

[0033] When the type block body 2 is assembled and fixed in the type block groove 3, the fixing part 7 is matched with the groove wall of the arc-shaped groove 10. Through the vertical limiting action of the arc-shaped groove 10, the up-down movement of the type block body 2 is limited, and the stable locking is realized. Embodiment three: please refer toFigures 13 to 22 The embodiment also provides a mold side plate with a quickly replaceable matrix block. The difference between the embodiment and the first and second embodiments is that: The rotating mechanism 8 comprises a vertical shaft 805 rotatably connected to the operation box 6, which extends in the vertical direction, and the fixing member 7 is fixed to the side wall of the vertical shaft 805. When the matrix block body 2 is assembled and fixed in the matrix groove 3, the fixing member 7 is in close contact with the top and bottom of the fixing groove 5. Through the surface contact, the fixing member 7 can vertically limit the matrix block body 2, prevent it from moving up and down along the depth direction of the matrix groove 3, and finally realize the stable locking of the matrix block body 2 in the matrix groove 3.

[0034] In the development process, it is found that during the vulcanization and molding of the tire, part of the molten rubber easily penetrates into the joint gap between the matrix block body 2 and the side plate body 1 and solidifies, resulting in tight adhesion between the two. In this case, it is difficult to break through the adhesion resistance of the solidified rubber only by relying on the elastic force of the elastic ejection mechanism 4, which affects the replacement efficiency of the matrix block body 2. In order to solve this problem, the following design is made: The bottom of the fixing member 7 is provided with first inclined surfaces 11 on the left and right sides, and first balls 12 are movably embedded in the bottom of the fixing groove 5. Through the rolling cooperation of the first inclined surfaces 11 and the first balls 12, the friction resistance when the fixing member 7 enters or exits the fixing groove 5 can be effectively reduced, and the operation smoothness is improved.

[0035] When the fixing member 7 rotates to exit the fixing groove 5 around the vertical shaft 805, the first inclined surface 11 and the first ball 12 cooperate to move the matrix block body 2 downward. Specifically, the first inclined surface 11 first contacts the convex surface of the first ball 12, and as the rotating action continues, the inclined surface transmits the pressure along the depth direction of the matrix groove 3 to the matrix block body 2 through the ball. The pressure forces the matrix block body 2 to move slightly downward against the pre-tightening force of the elastic ejection mechanism 4, thereby forming a shearing and peeling action on the solidified rubber in the gap and destroying its adhesion structure.

[0036] It should be noted that in order to ensure the reliability of the locking of the fixing member 7 to the matrix block body 2 and avoid loosening of the fixing member 7 due to vulcanization vibration, the top of the fixing groove 5 is also fixed with a gasket 21. The installation position of the gasket 21 is completely staggered (no spatial overlap) with the first ball 12, which can avoid interference with the ball action. When locking the matrix block body 2, after the fixing member 7 rotates into the fixing groove 5, its top surface is in close contact with the gasket 21 (forming a vertical upper limit), its bottom surface is in direct contact with the bottom of the fixing groove 5 (forming a vertical lower limit), and the bottom surface of the fixing member 7 is not in contact with the first ball 12 (as shown in FIG. 8). Through the design of the "double-directional limiting" structure, the stable vertical constraint of the matrix block body 2 is realized, and the displacement deviation of the matrix block during vulcanization is ensured. Figure 20 ​

[0037] It is worth mentioning that, in order to further ensure that the movable block body 2 can be stably ejected, a protrusion 13 is fixed on the side wall of the vertical shaft 805, and the top of the protrusion 13 movably embeds a second ball 14. A vertical groove 15 matched with the protrusion 13 is formed in the side wall of the movable block body 2, and the lower end of the vertical groove 15 extends to the bottom surface of the movable block body 2. A second inclined surface 16 is arranged on the top of the vertical groove 15.

[0038] When the protrusion 13 rotates around the vertical shaft 805 and enters the vertical groove 15, the movable block body 2 is moved upward through the cooperation of the second inclined surface 16 and the second ball 14. Specifically, after the fixed part 7 exits the fixed groove 5, the vertical shaft 805 continues to rotate and drives the protrusion 13 to enter the vertical groove 15. At this time, the second ball 14 contacts the second inclined surface 16 and generates an upward thrust force, which drives the movable block body 2 to move upward along the depth direction of the movable block groove 3. The upward moving distance is greater than the previous downward micro-moving distance, which not only completely offsets the downward micro-moving displacement, but also cooperates with the elastic force of the elastic ejection mechanism 4 to drive the movable block body 2 to completely separate from the movable block groove 3, thereby realizing stable ejection.

[0039] In the conventional scheme, the direct upward thrust needs to resist the surface adsorption force between the rubber and the movable block and the side plate and the overall resistance of the solidified rubber layer. Not only is the required thrust extremely large, but also after the local rupture of the rubber, part of the rubber may still be connected, causing the movable block to be stuck or the ejection height to be insufficient, which requires manual prying. However, in the present design, the relative displacement of the movable block side wall and the side plate gap generates a transverse shear force on the continuous rubber layer, directly cutting off the integrity of the rubber. The subsequent upward movement only needs to resist the local resistance of the scattered rubber debris, rather than the surface adsorption force of the complete rubber layer. The breaking resistance is reduced by more than 60%, greatly improving the ejection reliability and efficiency. Embodiment Four: The present embodiment also provides a tire mold, which comprises the mold side plate according to any one of the embodiments one to three. By adopting the mold side plate according to any one of the preceding embodiments, the tire mold not only ensures the molding precision of the tire side brand logo, specification number and other information after vulcanization, but also can adapt to the rapid changeover requirements of the tire production line for products of different specifications, thereby improving the overall operation reliability and use economy of the mold.
