At the same time as the material is heated and pressed, the air bag is inflated to form a hollow carbon fiber rim, wherein the air bag is uniformly expanded outward when subjected to gas pressure, and the cross-sectional shape of the carbon fiber rim is non-uniform Shape, so that at the same time of hot press forming, the side of the carbon fiber rim will be pressed by the large force of the air bag, so that the side of the carbon fiber rim is thinner, and the other parts are thicker, so that the thickness of the side of the rim is too low, so that The structural strength of the rim is reduced. Moreover, the traditional method of laminating the fiber cloth on the surface of the inflatable air bag often hinders the difference between the appearance of the air bag and the rim, and the elastic deformation amount (soft) when the air bag is inflated, so the process of laminating the fiber cloth is slow. Moreover, the accuracy of the stacking position is also poor, which in turn affects the overall thickness unevenness after the rim is formed. In addition, the method for manufacturing a bicycle rim according to the patent TW 1308527 is to inflate and heat the air bag in stages to obtain better high temperature resistance and wear resistance. However, the manufacturing method described in the patent Multiple stages of heating are required: Pressure and aeration processes make the production process more complex and slower. 201223788 SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a bicycle rim that is uniform in thickness and structural strength.

Set the thickness. , CT molding system, the outer mold is closed and closed, more specifically, the outer molds are placed against each other, so that the inner wall of the carbon fiber composite material is placed on the surface of the outer wall. Fixed in the cavity. In the forming process, 'listen to the outer mold 1 to pressurize and heat' and inflate in the Xia 3, so that the stone anti-fiber composite material can be found on the temperature and pressure side and pressed into a hollow carbon _ rim 4 ' as shown in Fig. 5 to Fig. 7 The rhyme rim 4 has a ring face 41 away from its center, and the carbon fiber rim 4 is formed by two projections of the outer die to form two grooves 42. The groove 42 is located on the annular top surface 4 of each of the grooves 42 and has a bottom surface 42 which is located on both sides of the rim 4 in the radial direction away from each other. The bag 3 is inflated' and the air bag portion extends to the outside of the outer mold i in combination with the inflatable tube member. In the separating outer mold, the outer mold 1 is opened, and the plurality of parts of the outer mold 1 are separated from each other, so as to take out the carbon fiber rim 4, and the carbon fiber rim 4 is separated from the outer mold 1, wherein The inner mold 2 and the air bag 3 are still left in the formed carbon fiber rim 4, and are taken out from the mold hole with the carbon fiber. In the process of disassembling the inner mold, at least two elongated openings 43' are formed before the annular top surface 41 of the carbon fiber rim, and the two openings are opened in 201223788 respectively. a bottom surface 421, and each of the openings 43 has a length smaller than each of the bottom surfaces, and then the inner mold 2 and the air bag 3 are taken out from the left and right sides of the two openings by using a clamp or a special missing device. The inner mold 2 and the air bag 3 are separated by the carbon fiber rim 4. Wherein, the inner mold 2 of the present invention is capable of bending and elastic deformation, but it still has a certain original appearance, and is also difficult to take from the airbag 3 to make the crucible 2 from the rim. The towel is taken out, and the invention has at least two opening holes in the annular top surface 41 of the carbon fiber rim 4, and the opening hole 43 is preferably elongated (rectangular or rectangular), and the elongated shape of the opening hole is determined by the wheel. The width, narrowness, or height of the circle increases the domain. The opening of the rim top surface is specially formed into an elongated shape and then disassembled into two or more (preferably four) inner dies 2, so that the inner mold 2 in the rim is smoothly opened from the two openings Clipped separately. In the trimming, a sheet 5 of a carbon fiber composite material is attached to the two openings 43 and bonded to the carbon fiber rim 4, and the sheet body 5 is a curved piece corresponding to the carbon fiber rim 4 • the paste surface 41. body. Preferably, the sheet 5 is bonded to the bottom surface 421 ′ of the two grooves, and the thickness of the sheet 5 is the same as the depth of the groove 42 so that the bonded sheet 5 and the ring are The top surface 41 is flush and the viscous σ system is used to fix the sheet 5 and the carbon fiber rim 4 to each other, and the fixing manner can be performed by using a colloid, or the hot body can be used to make the sheet 5 and the carbon fiber rim. 4 The surface is partially melted and can be combined and fixed.
