DETAILED DESCRIPTION

[0040] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0041] like Figures 1 to 11 As shown, a vulcanizer with a quick-connect mold includes a lower steam chamber 1 and a mold 2. The mold 2 is arranged on the upper end surface of the lower steam chamber 1. A plurality of radially movable sliders 6 are arranged on the circumference of the lower steam chamber 1. A swing member 7 is rotatably connected to the slider 6 through a rotating shaft 8. The swing member 7 is provided with a swing arm, which includes a pressing arm 72 and a pressing arm 71 at a certain angle.

[0042] A connecting boss 21 is provided on the lower side wall of the mold 2. The height of the rotating shaft 8 connected to the swinging member 7 of the utility model is higher than the upper end surface of the connecting boss 21;

[0043] In order to ensure that the initial position of the swing arm can be matched with the connecting boss 21 of the mold 2 with the help of the movement of the slider 6, an elastic member is preferably connected to the swing member 7, and the elastic member makes the clamping arm 71 face the connecting boss 21, and the elastic member makes the end of the clamping arm 72 be located above the upper end surface of the connecting boss 21, and the angle between the clamping arm 72 and the clamping arm 71 is preferably less than 90 degrees.

[0044] When the swing member 7 is driven to move toward the inner side of the lower steam chamber 1 by the above-mentioned structural slider 6, the clamping arm 71 can abut against the side wall of the connecting boss 21 and overcome the elastic force of the elastic member to drive the swing arm to swing so that the clamping arm 72 is pressed against the upper end surface of the connecting boss 21.

[0045] Specifically, the movement of the slider 6 causes the clamping arm 71 to abut against the side wall of the connecting boss 21 of the mold 2. As the slider 6 continues to move, the clamping arm 72 will be pressed against the upper end surface of the connecting boss 21. The fixed installation of the mold 2 is achieved only by the horizontal movement of the swing member 7, eliminating the problems of cumbersome installation and disassembly of the mold 2 and high operational safety risks, and avoiding the displacement of the mold 2 during the opening and closing movement to affect the appearance of the vulcanized tire.

[0046] The upper end surface of the lower steam chamber 1 of the utility model is preferably provided with a plurality of radially arranged T-shaped slide grooves 5, which are usually 4, 6 or 8 in a circumferential distribution according to the different molds 2 used, and a slider 6 is slid in the T-shaped slide groove 5, and the slider 6 is also correspondingly arranged in a T shape, and the slider 6 is connected to a linear drive device, which can drive the slider 6 to slide in the T-shaped slide groove 5. The linear drive device specifically includes a lead screw 4, and the slider 6 is screwed to the lead screw 4, and one end of the lead screw 4 is connected to a drive mechanism 10, which can drive the lead screw 4 to rotate, and the drive mechanism 10 can be a motor with a reducer, a hydraulic motor, or a blaster or other devices.

[0047] The elastic member is preferably configured as a torsion spring, one end of which is connected to the swing member 7 and the other end of which is connected to the slider 6. The torsion spring keeps the swing arm in a fixed position in a free state while ensuring that it can rotate along the rotating shaft 8 by a certain angle.

[0048] The utility model provides an annular wall 3 on the outer wall of the lower steam chamber 1, and a plurality of radial through holes are evenly distributed on the circumference of the annular wall 3. A lead screw 4 passes through the radial through holes and is connected to a driving mechanism 10. A sealing structure 9 is provided between the radial through holes and the lead screw 4 to ensure that the high-temperature and high-pressure gas in the steam chamber does not leak out during vulcanization.

[0049] The sealing structure 9 specifically includes a sealing ring 91 . A sealing installation groove is provided at one end of the radial through hole close to the driving mechanism 10 . The sealing ring 91 is installed in the sealing installation groove. A sealing gland 92 is provided outside the sealing ring 91 to fix the sealing ring 91 .

[0050] It also includes a sealing flange 93, which is connected to the annular wall 3. A lubricating element 94 is provided between the sealing flange 93 and the lead screw 4 to support the lead screw 4. The lubricating element 94 is preferably a self-lubricating bearing to reduce the friction resistance of the lead screw 4 when it rotates.

[0051] A bearing mounting hole is provided at one end of the sealing flange 93 of the utility model, and the bearing mounting hole is close to the annular wall 3, and a lubricating element 94 is arranged between the bearing mounting hole and the lead screw 4; a connecting hole is provided at the other end of the sealing flange 93 and is connected to the bearing mounting hole, and the aperture of the connecting hole is smaller than the aperture of the bearing mounting hole, and a lead screw step is provided at the end of the lead screw 4 close to the driving mechanism 10, and the lead screw step abuts on the transition surface between the connecting hole and the bearing mounting hole, thereby constraining the horizontal movement of the lead screw 4 and at the same time bearing the reaction force generated by the opening and closing of the mold 2 after clamping. A stopper 11 is preferably provided at the end of the T-shaped slide groove 5 away from the driving mechanism 10, and the stopper 11 supports the end of the lead screw 4. The utility model can also use the stopper 11 to constrain the lead screw 4.

[0052] The specific installation and disassembly process of the mold 2 of the utility model:

[0053] When installing the mold 2, the operator starts the linear drive device and retreats the slider 6 to the outside of the lower steam chamber 1 to make room for the installation of the mold 2; then the mold 2 is placed in a fixed position in the lower steam chamber 1 of the vulcanizer; the operator starts the drive mechanism 10 to drive the screw 4, and drives the slider 6 to approach the mold 2. When the clamping arm 71 on the slider 6 begins to contact the side wall of the connecting boss 21 of the mold 2, the slider 6 continues to approach the mold 2, which will drive the swing arm to rotate. This state continues until the clamping arm 72 presses against the upper end surface of the connecting boss 21. At this time, the slider 6 continues to approach the mold 2 to apply a pre-tightening force to the mold 2, so that the mold 2 is fastened to the upper end surface of the lower steam chamber 1, and the installation of the mold 2 is completed.

[0054] When the mold 2 is disassembled, the operator starts the linear drive device, the slider 6 moves away from the mold 2, the swing arm slowly breaks away from the contact with the mold 2, and returns to the initial state angle driven by the elastic member, until the slider 6 retreats to the farthest position from the mold 2, the operator lifts the mold 2 out of the lower steam chamber 1, and the disassembly of the mold 2 is completed.

[0055] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
