Description

Technical Field

[0001] This utility model relates to the field of solid tire processing technology, specifically a non-marking pressing and molding machine for processing non-marking solid tires. Background Technology

[0002] Solid tires are a type of tire that contrasts with pneumatic tires. Their carcass is solid, without a cord skeleton, and they do not require inflation, thus eliminating the need for an inner tube or airtight layer. The earliest tires were solid tires. Solid tires are used only on low-speed, high-load vehicles or machinery, and also on stationary machinery.

[0003] Solid tires are generally used under high loads, requiring the rubber compound to have sufficient pressure resistance and wear resistance. Therefore, most solid tires are manufactured using compression molding. During molding, the material to be molded is injected into a mold, and then the material in the mold is compressed. However, during the compression molding process, the material injected into the mold will overflow along the gaps in the mold. If the overflowing material is not cleaned up in time, it will cool and solidify, thus adhering to the compressed solid tire. This results in the need for further deburring and other treatments after the tire is demolded, which is not only time-consuming and labor-intensive, but also increases resource consumption and has poor overall practicality.

[0004] Therefore, we propose a non-marking compression molding machine for processing solid tires to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a non-marking compression molding machine for processing solid tires. This solves the problem mentioned in the background technology: solid tires are generally used under high loads, requiring the rubber material to have sufficient pressure resistance and wear resistance. Therefore, most solid tires are processed using compression molding. During molding, the material to be molded needs to be injected into a mold, and then the material in the mold is pressed. However, during the compression molding process, the material injected into the mold overflows along the mold gaps. If the overflowing material is not cleaned in time, it will cool and solidify, thus adhering to the pressed solid tire. This necessitates further deburring and other treatments after demolding the tire, which is not only time-consuming and labor-intensive but also increases resource consumption, resulting in poor overall practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of this utility model proposes a non-marking solid tire processing non-marking pressing molding machine, including a base 1, a bracket 2 fixedly connected to one side of the top of the base 1, a hydraulic cylinder 3 fixedly installed in the middle of the top of the bracket 2, an extension rod 4 connected to the output end of the hydraulic cylinder 3, a shaft 5 connected to the bottom of the extension rod 4, and an upper mold base 6 connected to the other end of the shaft 5.

[0027] An extension plate 7 is fitted on the outer ring surface of the top end of the shaft 5, and a drive motor 8 is fixedly mounted on the top of one end of the extension plate 7. The output end of the drive motor 8 is connected to a first pulley 9, and a transmission belt 10 is fitted on the outer surface of the first pulley 9. A second pulley 11 is connected to the inner side of the other end of the transmission belt 10. The second pulley 11 and the rotating seat 12 are rotatably connected to the shaft 5 through bearings. The bottom of the second pulley 11 is fixedly connected to the rotating seat 12, and a collection frame 13 is fixedly connected to the bottom of one end of the rotating seat 12 through a connecting rod. An inclined surface is provided on the side of the collection frame 13 near the mold base, and the curvature of the inclined surface fits the outer ring surface of the mold base. An opening is provided on one end surface of the collection frame 13, and a scraper structure is provided at the opening. A guide block 14 is fixedly mounted on the inner wall of the rotating seat 12. An arc-shaped surface is provided on the end of the guide block 14 away from the rotating seat 12, and the size of the arc-shaped surface is adapted to the size of the slot 16.

[0028] In use, the material for solid tire molding is pre-injected into the inner side of the lower mold base 18. Then, the hydraulic cylinder 3 longitudinally pushes the extension rod 4 fixedly connected to its bottom. The longitudinal movement of the extension rod 4 pushes the shaft 5, which in turn uses the movement of the shaft 5 to achieve the longitudinal movement of the upper mold base 6, facilitating subsequent contact between the upper mold base 6 and the lower mold base 18. When material overflows from the contact between the upper mold base 6 and the lower mold base 18, the drive motor 8 operates, causing the first pulley 9 connected to its output end to rotate. This rotation of the first pulley 9 drives the transmission belt 10 sleeved on its outer surface to move. The transmission belt 10 then drives the second pulley 11 connected to its inner side at the other end to rotate as well. Since the second pulley 11 and the rotating seat 12 are both connected... The bearing and shaft 5 form a rotatable connection, and the second pulley 11 and the rotating seat 12 form a fixed connection. Therefore, the rotation of the second pulley 11 can realize the rotation of the rotating seat 12, which facilitates the subsequent use of the rotation of the rotating seat 12 to drive the collection frame 13 to rotate along the outer ring surface of the mold, thereby collecting the overflowing material, reducing material damage, and preventing the overflowing material from sticking to the formed tire after cooling and molding. It is worth noting that the height of the collection frame 13 itself is the sum of the height of the upper mold seat 6 and the lower mold seat 18 when they are engaged, and the scraper structure set at the opening of the collection frame 13 will fit against the surface of the mold seat. In order to avoid affecting the power supply of the drive motor 8, the drive motor 8 can be driven to rotate in both directions in practice.

[0029] like Figure 1 and Figure 3 As shown, in some embodiments, a fixing plate 15 is fixedly connected to one side of the top of the upper mold base 6, and a slot 16 is provided on the side wall of the fixing plate 15. A positioning rod 17 is fixedly provided at the middle of the bottom end of the upper mold base 6, and a lower mold base 18 is fixedly provided at the middle of the top end of the base 1. A positioning groove 19 is provided at the middle of the top end of the lower mold base 18, and the inner diameter of the positioning groove 19 is adapted to the outer diameter of the positioning rod 17.

[0030] During use, the upper mold base 6 will move longitudinally under the action of the extension rod 4 and the shaft 5. At this time, the upper mold base 6 will come into contact with the lower mold base 18 during longitudinal movement. Then, the positioning rod 17 will be inserted into the inner side of the positioning groove 19 to provide a guiding effect for the connection between the two and prevent the upper mold base 6 and the lower mold base 18 from having positional deviation. When the rotating seat 12 is working, it will drive the guide block 14 fixed on its inner side wall to move along the slots 16 opened at both ends of the fixed plate 15. The slots 16 are used to improve the stability of the rotating seat 12 during circumferential movement.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the two ends of the shaft 5 are fixedly connected to the bottom of the extension rod 4 and the top center of the upper mold base 6, respectively, and the extension plate 7 is fixedly connected to the shaft 5.

[0032] When in use, the extension of the extension rod 4 will push the shaft 5 fixedly connected to its bottom, which in turn will push the upper mold base 6 to achieve the longitudinal movement of the upper mold base 6, and at the same time drive the extension plate 7 to adjust its position accordingly.

[0033] like Figure 2 As shown, in some embodiments, the rotating seat 12 is rotatably connected to the shaft 5 via a bearing seat, and the collecting frame 13 is symmetrically distributed along the vertical center line of the rotating seat 12.

[0034] When in use, the rotation of the second pulley 11 will drive the rotating seat 12 to rotate, which in turn causes the rotating seat 12 to drive the collection frame 13 to move in a circular motion along the surface of the mold, making it convenient to scrape and collect the overflowing material and reduce resource consumption.

[0035] like Figure 3 As shown, in some embodiments, the slots 16 are symmetrically distributed along the vertical center line of the fixing plate 15, and the slots 16 and the fixing plate 15 form an integrated structure.

[0036] When in use, the rotating seat 12 rotates in a circular motion, which drives the guide block 14 to rotate along the slots 16 opened at both ends of the fixed plate 15, thereby improving the stability of the rotating seat 12 during the movement.

[0037] In summary, the material for solid tire molding is pre-injected into the inner side of the lower mold base 18. Then, the hydraulic cylinder 3 works to push the extension rod 4. At this time, the longitudinal movement of the extension rod 4 causes the shaft 5 to push the upper mold base 6, which facilitates the subsequent fitting of the upper mold base 6 with the lower mold base 18. When material overflows from the upper mold base 6 and the lower mold base 18, the drive motor 8 works to drive the first pulley 9 to drive the transmission belt 10 to move. Then, the transmission belt 10 drives the second pulley 11 to rotate as well. The rotation of the second pulley 11 can realize the rotation of the rotating seat 12, which facilitates the subsequent rotation of the collecting frame 13 along the outer ring surface of the mold, thereby collecting the overflowing material, reducing material damage, and preventing the overflowing material from sticking to the molded tire after cooling and molding. It is worth noting that the height of the collecting frame 13 is the sum of the height of the upper mold base 6 and the lower mold base 18 when they are engaged, and the scraper structure set at the opening of the collecting frame 13 will fit against the surface of the mold base.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any 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.
