Then, the side walls 3 are respectively sandwiched by the two side molds 23 opposite to the first and second molds 21 and 22, and the first mold 2 i and the second mold 22 ′ are connected to each other via a high temperature of 180° C. or higher. And formed. Step 12: Since the first mold 21 is made of a metal material and is not elastic and cannot be directly removed from the outer frame 3, after the outer frame 3 is formed, the taper slider 211 must be removed first, and then the inner core is removed. Block 212. After the first mold 21 is removed, the second mold 22 of the silicone material is directly removed, and the side molds 23 are finally removed. Step 13. Referring also to Figure 5, the prepreg made of the fiber and the resin substrate is coated on the inflated air bag 25, and then placed in a third mold 24 having a cavity 241. The composite material is pressed against the air bag 25 to be closely adhered to the cavity 241 of the third mold 24, and then combined with the outer frame 3 as a part of the mold, and formed into a joint with the outer frame 3 by hot pressing. Finally, the third mold 24 is removed from the inner frame 4' to form a rim structure. The (four) 4 cross-section is an inverted triangle and is connected to the connecting wall 32 and the side wall 31 of the outer frame 3. Referring to Figure 6', the bicycle rim made by the above method includes a ring opening; an inner frame 4 and an annular outer frame 3.

After the inner tube is inflated, the fixed ends are pressed against the inner tube, so that the inner tube is It is fixed in the slot B and the capacity of the chamber is to reduce the weight of the rim and increase the riding speed of the ride. With the above structure, the advantages of the present invention are described as follows: 1. The outer frame 3 manufactured by the method has a resin substrate which can be a two-temperature resistant resin system, so that when the two sides are rubbed, the heat resistance of the rim manufactured by the method can be improved. strength. In one method, the outer frame 3 is first manufactured, and then the outer frame 3 is hot-pressed into a rim-rim structure, and in the manufacturing process, if the outer frame 3 is exhausted, it only needs to be scrapped. There is a 瑕 (4) frame 3, and it is not like the conventional one to scrap the entire rim, so it can improve the manufacturing yield of the product. The outer frame 3 is caused by the taper slider 211 and the inner inner block 212 ^ 'using the inclination of the taper slider 211 to urge the inner block 212 so that they are respectively pressed against each other The (4) 31, so only a small piece with a slope cone 201235228 degree slider 211 can be completed, which will save mold material costs. 4. Because the taper slider is 211 degrees, the contact area of the smaller volume can be used to keep the inner force 212 to be pushed outward, and thus the contact area is small, and the demoulding can be reduced when the mold is released. The resulting mold has the advantage of being easy. Referring to Figures 7 and 8, a second preferred embodiment of the method of manufacturing a bicycle rim of the present invention comprises four steps: step u 'step 12' step Μ and step 15. The step is the same as the step U and the step 12 of the first preferred embodiment. The difference lies in the step Μ and the step 15. Step 14: coating the prepreg made of the fiber and the resin substrate on an inflated air bag 25 >, and then placing it into a third mold 24 having a cavity 241, so that The composite material is pressed against the air bag and can be closely attached to the cavity 241 of the third mold 24/, and finally, with an outer cover 26, the third mold 24/ is removed after being formed by high temperature forming. The annular inner frame 4 structure, wherein the inner frame 4 > cross section is an inverted triangle type, the inner frame 4 / structure is not directly in contact with the brake piece, so a lower forming temperature resin system can be used, and the gas is used. The bag 25 is formed by inflation. Step 15: The side walls of the outer frame and the connecting wall are respectively connected to the inner frame 4 so that the outer frame surrounds the inner frame 4/, and then a rim structure is obtained. However, this is only a difference in steps, and the structure of the finished product is not much different from that of the first preferred embodiment, and is suitable for different use requirements. However, the above description is only a preferred embodiment of the present invention.
