Description

Technical Field

[0001] The utility model relates to the technical field of tire molds, in particular to a mold sleeve for a tire mold. Background Art

[0002] Tire molds are key equipment used for vulcanization molding of various types of tires. They play a vital role in the tire production process. Tire molds are the most important type of rubber molds, with a high degree of specialization, commercialization, and production concentration, and relatively high technical content. Structurally, tire molds are mainly composed of tread rings, mold sleeves, upper and lower side panels and other components. These components together constitute a closed vulcanization space. During the vulcanization process, the rubber material is heated and pressurized and molded according to the shape and pattern of the mold, thereby giving the tire specific appearance characteristics and structure. The mold sleeve, as an important component of the tire mold, is mainly used to fix and protect the tread rings and other components in the mold.

[0003] The existing Chinese patent with announcement number CN215965811U discloses a die sleeve for a stamping die, including a die template and a base plate. The die template is provided with a through hole that passes through itself and is symmetrically arranged. The bottom of the base plate is fixedly connected to a sleeve column corresponding to the through hole. The sleeve columns are provided in two and are symmetrically arranged. A tightening member with an inclined bottom is slidingly provided on one side of the two sleeve columns near the bottom end, and a spring is provided between the tightening member and the sleeve column; the top of the base plate is fixed with a die sleeve by nuts and bolts, and two sleeve columns are added to the bottom of the die through the arrangement of the through hole, sleeve column, tightening member and other structures, and are fixedly installed through the template.

[0004] Although the above scheme adopts the method of tightening the clamping parts to fix, and the disassembly and assembly are convenient and quick, when the mold sleeve is disassembled, since the die template is fixed on the mold frame of the mold, the subsequent operation space is small, and the operator needs to press the clamping parts hard during disassembly. The small space easily affects the size of the force, making disassembly more difficult. Therefore, it does not meet the existing needs. In this regard, we propose a mold sleeve for tire molds. Utility Model Content

[0005] The purpose of the present invention is to provide a mold sleeve for a tire mold, so as to solve the problem in the above background technology that the mold sleeve is difficult to remove after being installed on a tire mold frame, which affects the operating efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mold sleeve for a tire mold, comprising a die template, a seat plate is provided at the upper end of the die template, and the die template is fitted with the seat plate, a mold sleeve is provided at the upper end of the seat plate, and the mold sleeve is used for the tire mold, a first transmission cavity is opened at the middle position inside the die template, a second transmission cavity is opened on both sides inside the die template, a rotating shaft is provided inside the first transmission cavity, both ends of the rotating shaft extend to the inside of the second transmission cavity, and the rotating shaft is rotatably matched with the second transmission cavity, a double-threaded transmission rod is rotatably provided on the lower side of one side inside the second transmission cavity, and moving blocks are threadedly connected on both sides of the outside of the double-threaded transmission rod.

[0007] Preferably, blocks are provided on both sides of the lower end of the seat plate, and one end of the blocks extends into the interior of the second transmission cavity. The blocks are located in the second transmission cavity and have limiting grooves on both front and rear sides.

[0008] Preferably, two limiting blocks are welded to the upper side of the inner side of the moving block, and the limiting blocks are adapted to the limiting grooves.

[0009] Preferably, a transmission worm wheel is provided on the outer wall of the rotating shaft at one end inside the first transmission cavity, a transmission worm is rotatably provided on the upper side inside the first transmission cavity, and worm transmission is performed between the transmission worm and the transmission worm wheel.

[0010] Preferably, a rotating rod is welded to the front end of the transmission worm, one end of the rotating rod extends to the outside of the first transmission cavity, and the rotating rod rotates with the first transmission cavity, and a knob is installed at one end of the rotating rod located outside the first transmission cavity.

[0011] Preferably, guide rods are welded to the front and rear sides of the upper inner side of the second transmission cavity, and the guide rods pass through the moving block, and the guide rods are in sliding cooperation with the moving block.

[0012] Preferably, a rubber anti-skid pad is adhered and fixed to the upper end of the concave mold template, and the rubber anti-skid pad fits the seat plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a second transmission cavity on both sides of the inside of the die template. When the base plate and the die template are docked, the clamping block will be stuck in the inside of the second transmission cavity. By rotating the double-threaded transmission rod, the two moving blocks can be moved toward each other. When the two moving blocks move toward each other, they will drive the two limit blocks to move synchronously. Finally, the limit blocks will be stuck in the inside of the limit groove, so that the clamping block can be limited and fixed, avoiding the clamping block from escaping from the second transmission cavity. It only needs to rotate the double-threaded transmission rod in the opposite direction to make the moving block drive the limit block to move out of the panel of the limit groove, thereby realizing the rapid disassembly of the mold sleeve and increasing the efficiency of the operation.

[0015] 2. The utility model opens a first transmission cavity at the middle position inside the die template. By turning the knob, the rotating rod can drive the transmission worm to rotate. The transmission worm and the transmission worm wheel are driven by a worm, so the transmission worm wheel will drive the rotating shaft to rotate, and the rotating shaft will drive the synchronous rotation of the two double-threaded transmission rods in the second transmission cavity, so that the rotation of the two double-threaded transmission rods can be achieved by a single rotation, which reduces the operation time and further increases the efficiency of the mold sleeve disassembly. Moreover, since the worm transmission has self-locking properties, the double-threaded transmission rod is difficult to rotate when the knob is not turned, making it difficult for the moving block to move out of the inside of the limit groove, thereby ensuring the overall stability of the mold sleeve after installation.

[0016] 3. The utility model adheres and fixes a rubber anti-slip pad on the upper end of the die template. When the seat plate and the die template are docked and installed, the rubber anti-slip pad will be pressurized, thereby enhancing the friction between the die template and the seat plate, ensuring that the two are not prone to relative sliding or separation after connection. The rubber material can effectively absorb and disperse external impact and vibration due to its good elasticity and high friction coefficient, which not only improves the stability of the connection, but also reduces the risk of loosening due to long-term use or external force. In addition, the rubber anti-slip pad can fill the small gap between the die template and the seat plate to a certain extent, achieving a tighter fit, and further enhancing the overall stability and durability.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a mold sleeve for a tire mold, comprising a die plate 1, a seat plate 2 is provided at the upper end of the die plate 1, and the die plate 1 is fitted with the seat plate 2, a mold sleeve 3 is provided at the upper end of the seat plate 2, and the mold sleeve 3 is used for the tire mold, a first transmission cavity 4 is opened at the middle position inside the die plate 1, second transmission cavities 10 are opened on both sides of the inside of the die plate 1, a rotating shaft 6 is provided inside the first transmission cavity 4, both ends of the rotating shaft 6 extend to the inside of the second transmission cavity 10, and the rotating shaft 6 is rotatably matched with the second transmission cavity 10, a double-threaded transmission rod 11 is rotatably provided on the lower side of one side inside the second transmission cavity 10, and both sides of the outside of the double-threaded transmission rod 11 are threadedly connected with a moving block 12.

[0024] When in use, install the base plate 2 on the upper end of the die template 1, and install the die sleeve 3 simultaneously. After the lower end of the base plate 2 is in contact with the die template 1, squeeze the rubber anti-slip pad 17 to increase friction and prevent sliding. After the clamping block 14 is clamped into the second transmission cavity 10, turn the knob 9 to drive the rotating rod 8 and the transmission worm 7 to rotate, and then drive the transmission worm gear 5 and the rotating shaft 6 to rotate the double-threaded transmission rod 11. The moving block 12 slides along the guide rod 13 and moves toward each other, driving the limit block 15 to be clamped into the limit groove 16 of the clamping block 14 for fixation. The knob 9 can be turned in the opposite direction to quickly disassemble it, which is easy to operate.

[0025] See also Figure 2 and Figure 4 , a clamping block 14 is provided on both sides of the lower end of the seat plate 2, and one end of the clamping block 14 extends into the interior of the second transmission cavity 10. The clamping block 14 is located in the second transmission cavity 10. The front and rear sides of both sides are provided with limiting grooves 16. The clamping block 14 can be firmly inserted into the second transmission cavity 10, and the limiting groove 16 provides space for the subsequent clamping of the limiting block 15, ensuring that the connection between the seat plate 2 and the die template 1 is stable and reliable;

[0026] See also Figure 2 and Figure 4 , two limit blocks 15 are welded on the upper side of the inner side of the moving block 12, and the limit blocks 15 are adapted to the limit grooves 16. The limit blocks 15 can be accurately inserted into the limit grooves 16 to achieve clamping and fixing of the clamping blocks 14, thereby further stabilizing the connection between the seat plate 2 and the die template 1 to avoid loosening or falling off during use;

[0027] See also Figure 2 、 Figure 3 and Figure 4 , a transmission worm gear 5 is provided on the outer wall of the rotating shaft 6 at one end of the first transmission cavity 4, and a transmission worm 7 is rotatably provided on the upper side of the first transmission cavity 4, and a worm transmission is implemented between the transmission worm 7 and the transmission worm gear 5. The power transmission between the transmission worm 7 and the transmission worm gear 5 is realized by the worm transmission, which has the advantages of large transmission ratio, compact structure, good self-locking performance, etc., and can ensure that when the knob 9 is turned, the transmission worm gear 5 can drive the rotating shaft 6 and the double-threaded transmission rod 11 to rotate stably;

[0028] See also Figure 1 、 Figure 3 and Figure 4 , a rotating rod 8 is welded to the front end of the transmission worm 7, one end of the rotating rod 8 extends to the outside of the first transmission cavity 4, and the rotating rod 8 rotates with the first transmission cavity 4. A knob 9 is installed at one end of the rotating rod 8 located outside the first transmission cavity 4. The setting of the knob 9 is convenient for the operator to manually rotate, and the power is transmitted to the transmission worm 7 through the rotating rod 8 to start the entire transmission system. The operation is simple and easy to control;

[0029] See also Figure 2 and Figure 4 Guide rods 13 are welded on the front and rear sides of the upper side of the second transmission cavity 10. The guide rods 13 pass through the moving block 12 and slide with the moving block 12. The guide rods 13 provide a stable sliding track for the moving block 12, ensuring that the moving block 12 can maintain a straight line when rotating the double-threaded transmission rod 11, avoiding deviation or shaking during the movement process, and improving the stability and accuracy of the entire system.

[0030] See also Figure 2 and Figure 3 A rubber anti-skid pad 17 is adhered and fixed to the upper end of the die template 1, and the rubber anti-skid pad 17 fits with the seat plate 2. The rubber anti-skid pad 17 can increase the friction between the die template 1 and the seat plate 2, preventing relative sliding or separation between the seat plate 2 and the die template 1 due to vibration or external force during use, thereby ensuring the stable installation and long-term use of the mold sleeve 3.

[0031] Working principle: When in use, the seat plate 2 is installed from top to bottom on the upper end of the die template 1, so that the die sleeve 3 is installed synchronously. After the lower end of the seat plate 2 is fitted with the upper end of the die template 1, the rubber anti-slip pad 17 can be squeezed to increase the friction between the two, ensuring that the two are not prone to relative sliding or separation after connection. At this time, the clamping block 14 will be stuck in the inside of the second transmission cavity 10, grab the knob 9 and rotate it, the knob 9 will drive the rotating rod 8 to rotate, and the rotating rod 8 will drive the transmission worm 7 to rotate synchronously. Since the transmission worm 7 and the transmission worm gear 5 are worm-driven, the transmission worm gear 5 will drive the rotating shaft 6 to rotate synchronously, and the rotating shaft 6 will drive the synchronous rotation of the double-threaded transmission rods 11 inside the second transmission cavities 10 on both sides, and when the double-threaded transmission rods 11 rotate, they will drive the moving block 12 synchronously. With the rotation of the two moving blocks 12, since the moving blocks 12 are slidably matched with the guide rods 13, the moving blocks 12 will be subject to axial limitation, and the rotation of the two moving blocks 12 will be converted into horizontal linear movement in opposite directions, so that the two moving blocks 12 move toward each other, and the moving blocks 12 will drive the synchronous movement of the limiting blocks 15, so that the limiting blocks 15 are stuck in the limiting grooves 16 on both sides of the card block 14, so that the card block 14 can be clamped and fixed. Since the worm drive has self-locking properties, the stability after fixation is guaranteed, and the seat plate 2 is prevented from falling out. And only by rotating the knob 9 in the opposite direction, the double-threaded transmission rod 11 can be rotated in the opposite direction, so that the limiting blocks 15 are moved out of the limiting grooves 16, thereby realizing the rapid disassembly of the seat plate 2, increasing the efficiency of the operation, and being convenient and quick to use.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
