Description

Technical Field

[0001] The present invention relates to the technical field of extreme equipment, and more particularly, to an extreme wheel and a method for manufacturing the extreme wheel. Background Art

[0002] Extreme sports rollers, also known as extreme wheels, are used to be installed on special extreme equipment, such as extreme skateboards, extreme scooters, and extreme roller skates, and play a core supporting and moving role. Since extreme sports are difficult to operate, it is generally difficult for non-professional guidance or non-professionals to complete them independently, and they are often life-threatening. Therefore, the safety of extreme wheels is also of paramount importance.

[0003] In addition to ensuring the safety of users, the improvement of another performance of extreme wheels is also the first problem that needs to be solved. The comfort of extreme wheels. Due to the high difficulty of operating extreme sports, it depends to a large extent on the physical fitness and skills of the athletes themselves. Every display of extreme actions is constantly challenging the limits of human movement. In this case, keeping the athletes comfortable as much as possible can maximize the success rate of extreme sports actions.

[0004] For this reason, many extreme wheels with moderate hardness and softness have appeared on the market at this stage. Most of them change the hardness and softness of the extreme wheels by adjusting the material ratio of the extreme wheels. However, since the outer layer of the extreme wheels not only requires high elastic support and rebound, but also needs to have wear-resistant properties, the soft extreme wheels are comfortable to wear, but have poor wear resistance. Although the hard extreme wheels have good wear resistance, they are not comfortable to wear. Therefore, it is difficult to choose a suitable extreme wheel. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an extreme wheel and a method for manufacturing the extreme wheel. Through this process method, a double-layer extreme wheel with moderate softness and hardness is formed, which ensures safety performance while improving wearing comfort.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a method for manufacturing an extreme wheel, including the application of an extreme wheel manufacturing mold structure, wherein the extreme wheel manufacturing mold includes a bottom box and a top cover buckled on the bottom box, the top cover buckled on the bottom box to form an inner cavity, the top cover is provided with a through hole communicating with the inner cavity on a side away from the bottom box, and the inner side of the bottom box is provided with a convex edge protruding toward the top cover;

[0007] It also includes a first connecting tube and a second connecting tube that pass through the through hole and can be plugged into and matched with the convex edge, and the diameter of the first connecting tube is larger than the diameter of the second connecting tube;

[0008] Method and steps for making a limit wheel using the limit wheel making mold structure:

[0009] S1: The top cover is buckled onto the bottom box to form an inner cavity. The first connecting tube is inserted through the through hole and connected to the convex edge. The inner cavity is cut to form a first forming cavity and a second forming cavity. The first forming cavity is connected to the through hole. The raw material is poured into the first forming cavity through the through hole until it cools and forms a solidified outer support layer.

[0010] S2: After the outer supporting layer is formed and cooled, the first connecting tube is removed, and the wheel core is assembled on the convex edge. The second connecting tube replaces the first connecting tube and is inserted into the convex edge. At this time, a third forming cavity is formed in the inner cavity between the wheel core and the outer supporting layer, and the third forming cavity is opposite to the through hole.

[0011] S3: pouring another raw material into the third forming cavity through the through hole to form an internal elastic layer, and after the internal elastic layer is cooled, connecting the outer supporting layer and the wheel core through the internal elastic layer to form a limit wheel;

[0012] S4: Remove the second connecting tube, then demould the top cover and the bottom box to complete the production of the extreme wheel.

[0013] Preferably, in step S2, since the outer supporting layer is very easy to fit and adhere to the end of the first connecting tube when it is cooled and formed, the first connecting tube is provided with a stepped edge at one end close to the base box, and the first connecting tube is provided with a first clamping end at one end away from the base box, and a limiting groove is provided between the first clamping end and the main body of the first connecting tube.

[0014] Preferably, the diameter of the first clamping end is smaller than the diameter of the first connecting tube body.

[0016] A limit wheel includes a limit wheel made by the above-mentioned method of making a limit wheel, wherein the limit wheel includes an outer supporting layer, an inner elastic layer and a wheel core wrapped in sequence from the outside to the inside, the hardness of the outer supporting layer is greater than the hardness of the inner elastic layer, and the elasticity of the inner elastic layer is greater than the elasticity of the outer supporting layer.

[0017] To sum up, the present invention has the beneficial effects: based on the design of the double-layer extreme wheel, the extreme wheel is used to make the mold structure, and the two raw materials are poured into the mold in sequence until they are demolded and formed. Through this process method, a double-layer extreme wheel with moderate softness and hardness is formed, which ensures safety performance while improving wearing comfort.

[0025] Example 1: A method for making a limit wheel 4, see Figure 1, including the application of a mold structure based on the extreme wheel 4, the mold for manufacturing the extreme wheel 4 includes a bottom box 1 and a top cover 11 buckled on the bottom box 1, the top cover 11 buckled on the bottom box 1 to form an inner cavity 12, the top cover 11 is provided with a through hole 13 communicating with the inner cavity 12 on the side away from the bottom box 1, and a convex edge 14 is provided on the inner side of the bottom box 1 protruding toward the top cover 11;

[0026] The first connecting tube 2 and the second connecting tube 3 are inserted through the through hole 13 and can be plugged into the convex edge 14. The diameter of the first connecting tube 2 is larger than that of the second connecting tube 3.

[0027] Method and steps for making a mold structure using the limit wheel 4:

[0028] S1: The top cover 11 is fastened to the bottom box 1 to form an inner cavity 12. The first connecting tube 2 is inserted through the through hole 13 and connected to the ridge 14. The inner cavity 12 is cut to form a first forming cavity and a second forming cavity. The first forming cavity is connected to the through hole 13. The raw material is poured into the first forming cavity through the through hole 13 until it cools and forms a solidified outer support layer 41.

[0029] S2: After the outer supporting layer 41 is formed and cooled, the first connecting tube 2 is removed, and the wheel core 43 is assembled on the flange 14. The second connecting tube 3 replaces the first connecting tube 2 and is inserted into the flange 14. At this time, a third forming cavity is formed in the inner cavity 12 between the wheel core 43 and the outer supporting layer 41, and the third forming cavity is opposite to the through hole 13.

[0030] S3: Another raw material is poured into the third forming cavity through the through hole 13 to form an inner elastic layer 42. After the inner elastic layer 42 cools, the outer supporting layer 41 and the wheel core 43 are connected by the inner elastic layer 42 to form the limit wheel 4.

[0031] S4: Remove the second connecting tube 3, then demould the top cover 11 and the bottom box 1 to complete the production of the limit wheel 4.

[0032] This embodiment is based on the design of a double-layer extreme wheel 4, and uses the extreme wheel 4 to make a mold structure. The two raw materials are poured into the mold in sequence until they are demolded and formed. Through this process method, a double-layer extreme wheel 4 with moderate hardness is formed, which ensures safety performance while improving wearing comfort.

[0033] Specifically, in step S2, since the outer supporting layer 41 is very easy to fit and adhere to the end of the first connecting tube 2 when it is cooled and formed, the first connecting tube 2 is provided with a stepped edge 21 at one end close to the base box 1, and the first connecting tube 2 is provided with a first clamping end 22 at one end away from the base box 1, and a limiting groove 23 is provided between the first clamping end 22 and the main body of the first connecting tube 2.

[0034] After the outer support layer 41 of the first connecting tube 2 is formed, the first demolding step is required, i.e., the first connecting tube 2 is removed from the mold. To do this, an external connection member, such as a robot, grasps the first clamping end 22 and uses the limiting groove 23 to provide a gripping point to pull the first connecting tube 2 out of the mold. This facilitates the next step or process.

[0035] Specifically, the diameter of the first clamping end 22 is smaller than the diameter of the main body of the first connecting tube 2 .

[0036] Since the diameter of the main body of the first connecting tube 2 is smaller than the diameter of the through hole 13, space needs to be provided for the raw materials to enter the inner cavity 12. At this time, the design of the diameter of the first clamping end 22 being smaller than the diameter of the main body of the first connecting tube 2 also provides avoidance space for the raw materials to enter the inner cavity 12.

[0037] Specifically, when one end of the second connecting tube 3 is inserted into the fixed wheel core 43 on the convex edge 14 , the second connecting tube 3 is provided with a second clamping end 31 at the end away from the bottom box 1 , and the diameter of the second clamping end 31 is larger than the diameter of the second connecting tube 3 body.

[0038] The second connecting tube 3 needs to fix the wheel core 43 on the flange 14 at this time. To this end, one end of the second connecting tube 3 is inserted into the flange 14. At this time, the flange 14 and the second connecting tube 3 form a fixed clamp for the wheel core 43. The second clamping end 31 is used for clamping by an external manipulator. Since the diameter of the main body of the second connecting tube 3 is only slightly larger than the inner diameter of the wheel core 43, the diameter of the second clamping end 31 needs to be lengthened to facilitate grasping and disassembly.

[0039] Example 2: A limit wheel 4, see Figure 2 The difference between this embodiment and the first embodiment is that the limit wheel 4 is manufactured by the method of manufacturing the limit wheel 4 in the first embodiment, and the limit wheel 4 includes an outer support layer 41, an inner elastic layer 42 and a wheel core 43 wrapped in sequence from the outside to the inside. The hardness of the outer support layer 41 is greater than the hardness of the inner elastic layer 42, and the elasticity of the inner elastic layer 42 is greater than the elasticity of the outer support layer 41.

[0040] The outer supporting layer 41 and the inner elastic layer 42 are filled with plastic or rubber materials in a fluid state. Due to different raw material ratios, the hardness and elasticity are also different.

[0041] The wheel core 43 is made of PP, PC, or a nylon fiber mixed material. The hardness of the inner elastic layer 42 is controlled between 60HA and 90HA, and the hardness of the outer support layer 41 is controlled between 70HA and 100HA.

[0042] The rest of this embodiment is the same as that of the first embodiment. The features not explained in this embodiment are all based on the explanations of the first embodiment and will not be described in detail here.

[0043] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
