Description

Technical Field

[0001] This utility model relates to the field of tire mold technology, and in particular to a tire mold that is easy to demold. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, making contact with the road surface, and ensuring the vehicle's driving performance.

[0003] For example, Chinese Patent Publication No. CN219360074U discloses an easy-to-demold tire mold. Through the sliding connection between the disc and two limiting rods, and the sliding connection between the two push blocks and the inclined surfaces at both ends of the trapezoidal block, the two push blocks push the trapezoidal block and the disc upward, thereby causing the disc to push the top plate upward, and the top plate to push the tire out of the mold body, which makes it convenient for people to take the tire out.

[0004] The aforementioned comparative patent removes the tire from the mold by pushing the top plate upward with a disc. However, after the tire is formed, it may stick directly to the inner core of the mold. In this case, pushing it from the bottom can easily damage the tire and make it difficult to quickly place the tire blank before forming and remove the formed tire, thus reducing work efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an easy-to-demold tire mold to solve the problems of existing tire molds which are not easy to demold quickly after molding, and cannot quickly place tire blanks and pick up the molded tires, thus reducing work efficiency.

[0006] To achieve the above objectives, this utility model provides an easy-to-demold tire mold, including a base frame and a support frame. A fixed mold core is fixedly installed on the base frame, and a capsule inner membrane is fixedly sleeved on the fixed mold core. An air source for inflating and deflating the capsule inner membrane is provided inside the fixed mold core. A gripper for gripping tire blanks and forming tires is provided on the support frame. Four arc-shaped moving templates are slidably arranged on the base frame, and the inner walls of the arc-shaped moving templates can fit against the fixed mold core. The four arc-shaped moving templates can form a ring.

[0007] A movable disk is provided inside the bottom frame, and a transmission part is provided between the movable disk and each arc-shaped moving template. When the movable disk moves upward, it can simultaneously drive the four arc-shaped moving templates to separate from each other with the cooperation of multiple transmission parts.

[0008] Preferably, the transmission unit includes a connecting block fixedly connected to the arc-shaped moving template, and a connecting rod is hinged between the connecting block and the moving disk.

[0009] Preferably, the movable disk has an internal threaded hole, and a screw is rotatably connected to the top of the inner wall of the bottom frame, and the screw is threadedly connected to the internal threaded hole inside the movable disk. A drive motor is fixedly installed inside the bottom frame by a bracket, and the output end of the drive motor is connected to the bottom end of the screw.

[0010] Preferably, the air source includes an air passage opened inside the fixed mold core, and the air passage communicates with the inner membrane of the capsule. An air pipe communicating with the air passage is fixedly connected inside the fixed mold core, and channels for placing the air pipe are opened inside the fixed mold core and at the top of the bottom frame.

[0011] Preferably, a cylinder is provided between the gripper and the support frame, and the cylinder can push the gripper to move up and down.

[0012] Preferably, the gripper portion includes a fixing plate, the fixing plate has a through groove, a bidirectional screw is rotatably connected in the through groove, a second drive motor for driving the bidirectional screw to rotate is fixedly installed at the end of the fixing plate, two threaded sleeves are threadedly connected to the bidirectional screw, and a support block is fixedly connected to the bottom end of the threaded sleeve, and an arc-shaped clamping plate is fixedly connected to the bottom end of the support block.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an easy-to-demold tire mold includes a base frame 1 and a support frame 2. A fixed mold core 3 is fixedly installed on the base frame 1, and a capsule inner membrane 4 is fixedly sleeved on the fixed mold core 3. An air source part for inflating and deflating the capsule inner membrane is provided inside the fixed mold core 3. A gripper part for gripping the tire blank and forming the tire is provided on the support frame 2. Four arc-shaped moving templates 5 are slidably arranged on the base frame 1. The inner wall of the arc-shaped moving templates 5 can fit with the fixed mold core 3, and the four arc-shaped moving templates 5 can form a ring.

[0023] A movable disk 6 is provided inside the bottom frame 1. A transmission part is provided between the movable disk 6 and each arc-shaped moving template 5. When the movable disk 6 moves upward, it can simultaneously drive the four arc-shaped moving templates 5 to separate from each other with the cooperation of multiple transmission parts.

[0024] With the assistance of external mechanical grippers, the tire blank is transported to the top of the fixed mold core 3. Then, the gripper grabs the tire blank and places it on the fixed mold core 3. Subsequently, the inner membrane 4 of the capsule is inflated through the air source, so that the inner membrane 4 fixes the tire blank. Then, the moving disk 6 moves down, and with the assistance of the transmission unit, multiple arc-shaped moving templates 5 can come closer to each other, so that the arc-shaped moving templates 5 can fit with the fixed mold core 3 to form a seal, which facilitates the processing and molding of the tire blank.

[0025] In a preferred embodiment of the present invention, the transmission part includes a connecting block 7 fixedly connected to the arc-shaped moving template 5, and a strip groove for the connecting block 7 to move is provided on the bottom frame 1. A connecting rod 8 is hinged between the connecting block 7 and the moving disk 6.

[0026] The strip groove limits the movement trajectory of the connecting block 7, making the movement of the arc-shaped moving template smoother and more stable. Since one end of the connecting rod 8 is hinged to the connecting block 7 and the other end is hinged to the moving disk 6, when multiple arc-shaped moving templates 5 need to be closed, the moving disk 6 is driven to move down. Under the pull of multiple connecting rods 8, the moving disk 6 can pull multiple connecting blocks 7 closer to the fixed mold core 3, thereby driving multiple arc-shaped moving templates 5 to close with the fixed mold core 3 and close the mold.

[0027] In another preferred embodiment of this utility model, the interior of the movable disk 6 is provided with an internal threaded hole, and the top of the inner wall of the bottom frame 1 is rotatably connected to a screw 9, which is threadedly connected to the internal threaded hole inside the movable disk 6. A drive motor 10 is fixedly installed inside the bottom frame 1 by a bracket. The drive motor 10 is an integrated structure of a forward and reverse motor and a reducer. The output end of the drive motor 10 is connected to the bottom end of the screw 9.

[0028] When it is necessary to drive the moving disk 6 to move up and down, start the drive motor 10. The drive motor 10 drives the screw 9 to rotate. Since the screw 9 is threadedly connected to the internal threaded hole inside the moving disk, the connecting rod 8 and the connecting block 7 limit the rotation of the moving disk 6, so that the rotation of the screw 9 can drive the moving disk 6 to move up and down along the screw 9. Thus, with the cooperation of multiple connecting rods 8, multiple arc-shaped moving templates 5 can be pushed to move closer to each other or separate from each other at the same time.

[0029] In another preferred embodiment of the present invention, the air source includes an air channel 11 opened inside the fixed mold core 3, and the air channel 11 is connected to the inner membrane 4 of the capsule. An air pipe 12 connected to the air channel 11 is fixedly connected inside the fixed mold core 3. Channels for placing the air pipe 12 are opened inside the fixed mold core 3 and at the top of the bottom frame 1.

[0030] Air is supplied into the air tube 12 by an external air supply device, causing the inner membrane 4 of the capsule to expand and fix the tire blank held by the gripper. After the tire is formed, the gripper holds the formed tire and then releases the air from the inner membrane 4 of the capsule to release the fixation on the formed tire, making it easier for the gripper to remove the formed tire.

[0031] It should be noted that a cylinder 13 is provided between the gripper and the support frame 2. The cylinder 13 can push the gripper to move up and down.

[0032] The gripper part includes a fixing plate 14, on which a through groove is provided. A bidirectional screw 15 is rotatably connected in the through groove. A second drive motor 18 for driving the bidirectional screw 15 to rotate is fixedly installed at the end of the fixing plate 14. The second drive motor 18 is an integrated structure consisting of a forward and reverse motor and a reducer. Two threaded sleeves 16 are threadedly connected to the bidirectional screw 15. The bidirectional screw 15 has two threaded segments with opposite directions of rotation. The two threaded sleeves 16 are threadedly connected to their respective threaded segments. A support block is fixedly connected to the bottom end of the threaded sleeve 16. An arc-shaped clamping plate 17 is fixedly connected to the bottom end of the support block.

[0033] When the formed tire needs to be removed, cylinder 13 pushes the fixing plate 14 downward to the appropriate position, and then the second drive motor 18 is started. The second drive motor 18 drives the bidirectional screw 15 to rotate. Since the bidirectional screw 15 is threadedly connected to the two threaded sleeves 16, and the through groove restricts the rotation of the threaded sleeves 16, the two threaded sleeves 16 can drive the two arc-shaped clamping plates 17 to move closer to each other, thereby clamping the formed tire. Then the inner membrane 4 of the capsule is deflated, and cylinder 13 drives the fixing plate to rise to the appropriate position, so that the tire can be removed with the help of the external robot arm.

[0034] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0035] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
