Description

Technical Field

[0001] The invention relates to the technical field of tire molds, in particular to a novel positioning device for two half molds of an engineering tire. Background Art

[0002] Engineering tires are specially designed for engineering vehicles. They are characterized by high load-bearing, wear-resistant and impact-resistant. They are divided into various types to adapt to different equipment and working conditions and are widely used in construction, mining, metallurgy and other fields. When choosing, you need to consider the working environment, equipment specifications, tire performance and brand quality. The two-half mold is the key equipment for the vulcanization molding of engineering tires. It consists of an upper mold and a lower mold and is used to manufacture thick-walled, high-load tires such as engineering tires.

[0003] In the production process of existing engineering tires, the patterns on some tires have certain rotational patterns according to actual use requirements, and the tires with rotational patterns have inclined ribs. When the upper mold and the lower mold are opened, the oblique protruding ribs on the upper mold and the lower mold nickel coins correspond to the concave patterns on the tire, so the mold will rotate when the mold is opened. Before the rotated mold is closed, it is necessary not only to stop the rotation of the mold by a tool, but also to adjust the mold rotation to a suitable position by positioning for the closing operation. In order to further improve the efficiency of engineering tire production, based on this, a new type of engineering tire two-half mold positioning device is now provided, which can eliminate the disadvantages of the existing device.

[0045] The lifting mechanism includes: a first bracket 306 fixedly connected to the top of the second bracket 4, a motor 301 is installed on the top of the first bracket 306, a synchronous belt 303 is arranged on the top of the second bracket 4, the synchronous belt 303 is located on the inner side of the first bracket 306, two transmission wheels 302 are symmetrically arranged inside the synchronous belt 303, the synchronous belt 303 is meshed and sleeved on the outer walls of the two transmission wheels 302, one transmission wheel 302 is fixedly connected to the output end of the motor 301, the bottom ends of the two transmission wheels 302 are fixedly connected to the screw rod 304 through the connecting shaft, the screw rod 304 is located on the inner side of the second bracket 4, the outer wall of the screw rod 304 is sleeved with a lifting push plate 305, the lifting push plate 305 is threadedly connected to the screw rod 304, the lifting push plate 305 is located on the outer side of the lifting ring 204, the lifting push plate 305 is fixedly connected to the lifting ring 204, and the upper mold 5 can be driven to lift stably through the cooperation of the lifting mechanism and the positioning mechanism;

[0046] In this embodiment, when in use, the starting motor 301 drives one transmission wheel 302 to rotate, and at this time, the synchronous belt 303 drives the other transmission wheel 302 to rotate under the meshing drive of one transmission wheel 302, and at the same time, the screw rod 304 rotates synchronously under the drive of the transmission wheel 302 through the connecting shaft, and at this time, the lifting push plate 305 drives the upper mold 5 to rise synchronously through the positioning mechanism under the drive of the screw rod 304 through the thread, and at this time, the upper mold 5 is separated from the lower mold 6 by movement, so that the upper mold 5 and the lower mold 6 can be opened;

[0047] During this process, the upper mold 5 rotates along the lines on the outer wall of the engineering tire through the lines on the inner wall. At this time, the upper mold 5 can be squeezed by the positioning mechanism to stop rotating, thereby preventing the upper mold 5 from continuing to rotate;

[0048] After that, the engineering tire formed in the inner cavity of the lower mold 6 is taken out. When the next engineering tire needs to be formed, the motor 301 is started to drive a transmission wheel 302 to rotate in the opposite direction, so as to reverse the above operation, so that the upper mold 5 and the lower mold 6 can be closed.

[0055] A rolling assembly is provided on the fixed swivel 2011;

[0056] The rolling assembly includes: two groups of balls 205 symmetrically arranged inside the lifting ring 204, the two groups of balls 205 are respectively located at the upper and lower ends of the fixed rotating ring 2011, and the two groups of balls 205 are in contact with the outer wall of the fixed rotating ring 2011. Through the cooperation between the moving assembly and the rolling assembly, the friction between the fixed rotating ring 2011 and the lifting ring 204 can be reduced during the rotation of the upper mold 5.

[0057] A friction component is provided on the lifting ring 204;

[0058] In one embodiment, Figure 2-Figure 6 As shown, the friction component is a limit pressure ring 206 disposed below the lifting ring 204, and the limit pressure ring 206 is located on the outer side of the upper mold 5;

[0059] A limiting component is provided on the limiting pressure ring 206;

[0060] The limiting assembly includes: a plurality of limiting slide bars 203 fixedly connected to the top of the limiting pressure ring 206 at equal intervals in the circumferential direction, the plurality of limiting slide bars 203 all penetrate to the outside of the top of the lifting collar 204, the plurality of limiting slide bars 203 are all slidably connected to the lifting collar 204, and the tops of the plurality of limiting slide bars 203 are all fixedly connected to the limiting baffle 202;

[0061] A reset component is provided on the limit slide bar 203;

[0062] The reset component is a spring 201 sleeved on the outer wall of the limiting slide rod 203. One end of the spring 201 contacts the outer wall of the limiting baffle 202, and the other end of the spring 201 contacts the outer wall of the lifting ring 204. Through the mutual cooperation of the friction component, the limiting component and the reset component, the upper mold 5 can stop rotating through friction force.

[0063] The above embodiment discloses a novel two-half mold positioning device for engineering tires, wherein when in use, the starting motor 301 drives a transmission wheel 302 to rotate, and at this time, the synchronous belt 303 drives the other transmission wheel 302 to rotate under the meshing drive of one transmission wheel 302, and at the same time, the screw rod 304 rotates synchronously under the drive of the transmission wheel 302 through the connecting shaft, and at this time, the lifting push plate 305 drives the lifting ring 204 to rise through the thread driven by the screw rod 304, and at the same time, the fixed rotating ring 2011 drives the upper mold 5 to rise synchronously through the two groups of balls 205 under the drive of the lifting ring 204, and at this time, the upper mold 5 is separated from the lower mold 6 by movement, and at the same time, the docking ring 207 drives the guide slide bar 2010 to move synchronously under the drive of the upper mold 5, so that the upper mold 5 and the lower mold 6 can be opened;

[0064] During this process, the upper mold 5 rotates along the lines on the outer wall of the engineering tire through the inner wall lines. At this time, the fixed swivel 2011 rotates along the outer wall of the two groups of ball bearings 205 driven by the upper mold 5 through the bolts. When the limit baffle 202 contacts the top of the inner wall of the second bracket 4, the limit baffle 202, under the obstruction of the inner wall of the second bracket 4, pushes the limit pressure ring 206 to stop moving through the limit slide bar 203. At the same time, the lifting ring 204 slides along the outer wall of the plurality of limit slide bars 203 and contracts through the moving extrusion spring 201, so that the limit pressure ring 206 and the lifting ring 204 can be separated from each other. When the lower surface of the limit pressure ring 206 contacts the upper surface of the docking ring 207, the docking ring 207 drives the upper mold 5 to stop rotating under the friction and extrusion of the limit pressure ring 206, thereby preventing the upper mold 5 from continuing to rotate.

[0065] Afterwards, the engineering tire formed in the inner cavity of the lower mold 6 is taken out. When it is necessary to mold the next engineering tire, the motor 301 is started to drive a transmission wheel 302 to rotate in the opposite direction, so as to reverse the above operation, so that the upper mold 5 and the lower mold 6 can be closed. During this process, when the guide slide bar 2010 contacts the inner wall of the arc guide groove 209, the guide slide bar 2010 slides along the inner wall of the arc guide groove 209 through the docking ring 207 under the push of the upper mold 5. At the same time, the upper mold 5 rotates through the docking ring 207 under the drive of multiple guide slide bars 2010 until the guide slide bar 2010 contacts the inner wall of one end of the arc guide groove 209. At this time, the upper mold 5 contacts the upper surface of the lower mold 6, so that the upper mold 5 can be automatically rotated and positioned, thereby further improving the efficiency of engineering tire production.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
