Description

Technical Field

[0001] This utility model relates to the field of vulcanized capsule technology, specifically to an adjustable mold capsule chuck structure. Background Technology

[0002] Tire vulcanization refers to the vulcanization of the outer tire, which is carried out using a mold pressurization method. Its characteristic is that the outer diameter of the tire blank is smaller than the inner diameter of the mold. During vulcanization, the tire blank is filled with a water-filled tubing or bladder, and high-pressure hot water is injected into the water-filled tubing. The expansion pressure of the water-filled tubing or bladder forces the outer tire blank to fill the mold. The outer tire vulcanization process employs a gradual heating and low-temperature, long-term vulcanization method to ensure sufficient flow and heat transfer of the rubber compound, thus guaranteeing vulcanization quality.

[0003] A search revealed that utility model patent CN207359443U discloses a tire vulcanizing bladder chuck structure, including a tray, a lower clamping plate, and a lower steel ring. The lower clamping plate and the lower steel ring are mounted on the tray, which is connected to a central mechanism. The lower clamping plate and the lower steel ring are bolted together to clamp the lower bladder root. The lower steel ring is bolted to the tray and has clearance holes. The lower clamping plate has inlet and outlet water pipes, which correspond to the clearance holes on the lower steel ring. This patent, without changing the central mechanism, can vulcanize tires with smaller diameters by modifying the clamping structure, improving the versatility of the central mechanism and increasing the utilization rate of idle equipment.

[0004] However, the existing bladders have a relatively fixed diameter and their size cannot be adjusted. When they stretch and contract, the edges are larger than the chuck and the tire bead opening. When the equipment automatically lowers the tire for loading, the tire bead opening touches the bladder surface. During shaping, the tire gets stuck on the edge of the bladder, resulting in tire appearance defects such as bladder entrapment and misaligned loading, as well as affecting production continuity. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable mold capsule chuck structure, which solves the problem that the diameter of existing capsules is relatively fixed and the size cannot be adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable mold capsule chuck structure, including a mold, a fixed plate mounted on the bottom of the mold by bolts, a telescopic shaft slidably connected inside the fixed plate, the telescopic shaft penetrating the fixed plate, a chuck fixedly connected to the upper section of the telescopic shaft, multiple sliding columns slidably connected inside the chuck, a connecting seat fixedly connected to the end of each sliding column, a capsule fixedly connected between the connecting seat and the fixed plate, a sliding rod fixedly connected to the column, the sliding rod penetrating the chuck and slidably connected to the chuck, a rotating disk mounted on the telescopic shaft above the chuck via a bearing, an arc groove formed inside the rotating disk, the arc groove penetrating the rotating disk, the sliding rod penetrating the arc groove and slidably connected to the arc groove, a locking mechanism provided on the telescopic shaft, and two limiting rings fixedly connected to the rod, the two limiting rings respectively contacting the upper and lower surfaces of the rotating disk.

[0007] Preferably, a sealing film is fixedly connected to multiple connecting seats, and the sealing film is fixedly connected to the telescopic shaft. The sealing film provides a sealing effect for the area between the telescopic shaft, the connecting seats, and the capsule.

[0008] Preferably, the locking mechanism includes a hollow shell fixedly connected to the telescopic shaft. A locking pin is slidably connected to the bottom of the hollow shell, and the locking pin penetrates the hollow shell. The locking pin is inserted into the rotating disk. A hollow sleeve is fixedly connected to the upper end of the locking pin. A sloping groove is formed inside the hollow sleeve, and the sloping groove penetrates the hollow sleeve. A push rod is slidably connected to the right side wall of the hollow shell, and the push rod penetrates the hollow shell. One end of the push rod inside the hollow shell abuts against the sloping part of the sloping groove. The locking mechanism effectively locks and fixes the rotating disk after rotational adjustment, thereby stabilizing the adjusted chuck diameter.

[0009] Preferably, a pressing block is fixedly connected to one end of the push rod located outside the hollow shell, and the pressing block and the push rod are an integral structure. The pressing block facilitates the pushing of the push rod.

[0010] Preferably, a magnetic ring is fixedly connected to the push rod, and the magnetic ring is attracted to the inner wall of the hollow shell. The magnetic ring provides auxiliary fixation for the push rod.

[0011] Preferably, a spring is sleeved on the outer side of the locking pin, one end of the spring is fixedly connected to the hollow sleeve, and the other end of the spring is fixedly connected to the inner surface of the hollow shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model sets multiple sliding pillars that can slide radially within the original chuck, with a connecting seat at the end of each sliding pillar. The connecting seats are sealed with sealing films. A sliding rod that penetrates the chuck is then set on the sliding pillar. In addition, a rotating disk is mounted on the telescopic shaft with a bearing. The sliding rod can pass through the arc groove of the rotating disk. In this way, by rotating the rotating disk and using the cooperation of the arc groove and the sliding rod, the sliding pillar can telescopically move within the chuck. This allows the diameter of the chuck to be controlled by the connecting seat, preventing the airbag opening from being too large, which would cause the embryo to get stuck at the edge of the capsule during mold closing.

[0014] 2. This utility model provides a locking mechanism on the telescopic shaft. By pressing the push rod with the pressing block, the push rod slides in the inclined groove of the hollow sleeve, which can control the telescopic shaft of the locking pin, thereby controlling the engagement and disengagement of the locking pin with the rotating disk. In this way, after the rotating disk is rotated and adjusted, the rotating disk can be locked and fixed by the locking pin, thus stabilizing the diameter of the adjusted chuck.

A rotating disk 8 is mounted on the shaft of the telescopic shaft 3 above the chuck 4 via a bearing. An arc groove is opened inside the rotating disk 8 and passes through the rotating disk 8. The sliding rod 7 passes through the arc groove and is slidably connected to the arc groove. Two limiting rings 10 are fixedly connected to the rod of the sliding rod 7 and contact the upper and lower surfaces of the rotating disk 8, respectively. A sealing film 11 is fixedly connected to multiple connecting seats 6, and the sealing film 11 is fixedly connected to the telescopic shaft 3. The sealing film 11 provides a sealing effect for the area between the telescopic shaft 3, the connecting seats 6 and the capsule 12.

[0022] Please see Figure 3-4 A locking mechanism 9 is provided on the shaft of the telescopic shaft 3. The locking mechanism 9 has the function of locking and fixing the rotating disk 8 after rotation adjustment, thereby stabilizing the diameter of the adjusted chuck 4. The locking mechanism 9 includes a hollow shell 91 fixedly connected to the shaft of the telescopic shaft 3. A locking pin 92 is slidably connected to the bottom of the hollow shell 91 and is set through the hollow shell 91. The locking pin 92 is inserted into the rotating disk 8. A hollow sleeve 93 is fixedly connected to the upper end of the locking pin 92. A sloping groove is opened inside the hollow sleeve 93 and is set through the hollow sleeve 93. A push rod 95 is slidably connected to the right side wall of the hollow shell 91 and is set through the hollow shell 91. One end of the push rod 95 inside the hollow shell 91 abuts against the sloping part of the sloping groove.

[0023] Please see Figure 4 A pressing block 96 is fixedly connected to one end of the push rod 95 located outside the hollow shell 91, and the pressing block 96 and the push rod 95 are an integral structure.

[0024] The specific implementation process of this utility model is as follows: In use, firstly, the push rod 95 is pushed by the pressing block 96. The push rod 95 slides in the inclined groove inside the hollow sleeve 93, thereby causing the hollow sleeve 93 to be pushed upward, which in turn drives the locking pin 92 to move upward and separates the locking pin 92 from the rotating disk 8, thereby releasing the restriction on the rotating disk 8. Then, the rotating disk 8 is rotated. Then, by using the cooperation of the arc groove and the slide rod 7, the slide column 5 can be extended and retracted in the chuck 4, thereby controlling the diameter of the chuck 4 through the connecting seat 6, avoiding the airbag opening being too large, which would cause the embryo to get stuck on the edge of the capsule 12 when the mold is closed.
