Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber products technology, and in particular to a rubber wheel and its rubber mold. Background Technology
[0002] In cableway systems, metal wheel bushings are prone to severe friction with the traction rope, accelerating rope wear and potentially leading to rope breakage under long-term operation, seriously threatening the operational safety of the cableway system. To address this issue and improve the durability and safety performance of the cableway system, a common practice is to add a rubber wheel around the outer circumference of the metal wheel bushing. This solution provides a rubber mold for manufacturing a new type of rubber wheel. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a rubber wheel and its rubber mold. The rubber wheel can carry a traction rope and allows the traction rope to swing within a certain range.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A rubber wheel includes an integrally molded base ring and two wing rings.
[0006] The wing ring is trumpet-shaped, and the two wing rings are symmetrically arranged on the top and bottom surfaces of the base ring. The side with the smaller inner diameter of the wing ring is connected to the outer right angle of the base ring.
[0007] The outer wall of the base ring is provided with an arc-shaped groove.
[0008] Furthermore, both the inner and outer walls of the wing ring are designed as curved surfaces.
[0009] A rubber mold for preparing the rubber wheel.
[0010] Furthermore, the rubber mold includes an upper mold, a middle mold, a lower mold, and a core mold arranged coaxially. The upper mold and the lower mold are respectively located at the top and bottom of the middle mold, and the core mold is located inside the middle mold. The top and bottom surfaces of the core mold are respectively in close contact with the upper mold and the lower mold. An injection space is formed between the outer wall of the core mold, the inner wall of the middle mold, the upper mold, and the lower mold. The shape of this space is consistent with the shape of the rubber wheel.
[0011] Furthermore, the top circumferential array of the upper mold has multiple injection holes, and the bottom of the injection holes is connected to the corresponding top position of the wing ring in the injection space.
[0012] Furthermore, the outer periphery of the top of the core mold is provided with a first step notch, and the outer periphery of the bottom of the upper mold is provided with a first step, the first step matching the first step notch.
[0013] Furthermore, the outer periphery of the bottom of the core mold is provided with a second step notch, and the outer periphery of the top of the lower mold is provided with a second step, the second step matching the second step notch.
[0014] Furthermore, the outer wall of the upper mold is provided with a ring of upper mold openings, and the bottom surface of the upper mold openings is the top surface of the middle mold.
[0015] Furthermore, the outer wall of the lower mold is provided with a ring of lower mold openings, and the top surface of the lower mold openings is the bottom surface of the middle mold.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. A new type of rubber wheel is provided, which can be fitted onto a metal wheel bushing. The rubber wheel supports the traction rope, and through the buffering and protection function of the rubber wheel, the wear on the traction rope can be reduced, ensuring the safe and stable operation of the cableway. When the rubber wheel is worn out, it can be disassembled and replaced with a new rubber wheel, and the wheel bushing can be reused repeatedly.
[0018] 2. A new rubber mold is provided for preparing the rubber wheel. The mold has a simple structure and is easy to assemble. Attached Figure Description
[0019] Figure 1 A structural diagram of the rubber wheel of Example 1 is shown;
[0020] Figure 2 A cross-sectional view of the rubber mold of Example 2 is shown. Detailed Implementation
[0021] Example 1
[0022] like Figure 1 As shown, this embodiment provides a rubber wheel, including an integrally formed base ring 41 and two wing rings 42.
[0023] Specifically, the outer wall of the base ring 41 is provided with an arc-shaped groove 411, which is used to support the traction rope of the cableway system. The wing rings 42 are trumpet-shaped, and two wing rings 42 are symmetrically arranged on the top and bottom surfaces of the base ring 41. Figure 1 As can be seen, the side with the smaller inner diameter of the wing ring 42 is connected to the outer right angle of the base ring 41. The inner wall of the wing ring 42 is set as a first arc surface, and the outer wall of the wing ring 42 is set as a second arc surface. The inner diameter of the second arc surface is larger than that of the arc groove 411.
[0024] Normally, the traction rope is located within the arc-shaped groove 411. When the wind force is too strong, causing the traction rope to swing significantly, the traction rope may extend beyond the arc-shaped groove 411 and move into the range of the wing ring 42. Therefore, the function of the wing ring 42 is to accommodate the traction rope and limit its swing amplitude, thereby improving safety. When the wind force is low, the traction rope can automatically return to the arc-shaped groove 411, and the wing ring 42 will not hinder the return of the traction rope.
[0025] In use, the rubber wheel is fitted onto the metal wheel bushing, and two support rings are added to the metal wheel bushing. The two support rings are fixed to the two sides of the metal wheel bushing by multiple bolts. The support rings can provide sufficient support to the inner wall of the wing ring 42 to prevent the wing ring 42 from deforming. The support rings also prevent the rubber wheel from detaching from the metal wheel bushing.
[0026] The rubber wheel's cushioning and protective function reduces wear on the traction rope, ensuring the safe and stable operation of the cableway. When the rubber wheel wears out, the bolts on the support ring can be loosened, the rubber wheel removed, and a new rubber wheel replaced, allowing the wheel liner to be reused repeatedly.
[0027] Example 2
[0028] like Figure 2 As shown, this embodiment provides a rubber mold for the rubber wheel described in Embodiment 1.
[0029] Specifically, the rubber mold includes an upper mold 1, a middle mold 2, a lower mold 3, and a core mold 5 arranged coaxially. The upper mold 1 and the lower mold 3 are respectively located at the top and bottom of the middle mold 2. The core mold 5 is located inside the middle mold 2, and the top and bottom surfaces of the core mold 5 are respectively in close contact with the upper mold 1 and the lower mold 3. An injection space is formed between the outer wall of the core mold 5, the inner wall of the middle mold 2, the upper mold 1, and the lower mold 3. The shape of this space is consistent with the shape of the rubber wheel.
[0030] More accurately, such as Figure 1 , Figure 2 As shown, the injection space between the outer wall of the core mold 5 and the inner wall of the middle mold 2 corresponds to the base ring 41 of the rubber wheel, the injection space between the upper mold 1 and the inner wall of the middle mold 2 corresponds to one wing ring 42 of the rubber wheel, and the injection space between the lower mold 3 and the inner wall of the middle mold 2 corresponds to the other wing ring 42 of the rubber wheel.
[0031] More accurately, such as Figure 1 , Figure 2 As shown, the top circumferential array of the upper mold 1 has multiple injection holes 11, and the bottom of the injection holes 11 is connected to the position of the top of the corresponding wing ring 42 in the injection space.
[0032] More specifically, such as Figure 2 As shown, the outer periphery of the top of the core mold 5 is provided with a first step notch 51, and the outer periphery of the bottom of the upper mold 1 is provided with a first step 12. The first step 12 matches the first step notch 51. This design has two purposes: first, to ensure that the core mold 5 and the upper mold 1 are coaxially set, and second, to improve the sealing performance.
[0033] More specifically, such as Figure 2 As shown, the outer periphery of the bottom of the core mold 5 is provided with a second step notch 52, and the outer periphery of the top of the lower mold 3 is provided with a second step 31. The second step 31 matches the second step notch 52. This design has two purposes: first, to ensure that the core mold 5 and the lower mold 3 are coaxially set, and second, to improve the sealing performance.
[0034] More specifically, such as Figure 2 As shown, the contact area between the upper mold 1 and the middle mold 2 is matched by a step. Similarly, the contact area between the lower mold 3 and the middle mold 2 is also matched by a step. This design serves two purposes: first, to ensure that the upper mold 1, lower mold 3 and middle mold are coaxially set; and second, to improve sealing.
[0035] More specifically, such as Figure 2 As shown, the outer wall of the upper mold 1 is provided with an upper mold release opening 13, the bottom surface of which is the top surface of the middle mold 2; the outer wall of the lower mold 3 is provided with a lower mold release opening 32, the top surface of which is the bottom surface of the middle mold 2. The function of the upper mold release opening 13 and the lower mold release opening 32 is to facilitate the disassembly of the mold.
[0036] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
