Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] Preparatory work is carried out before production, including raw material preparation, prepreg preparation, Y-shaped latex liner preparation, mold preparation, mold cleaning, machine preheating, etc. When making, first apply a layer of release agent on the surface of the mold (in this example, Henkel Frekote 55-NC release agent is selected), so as to ensure the smooth release of the product after molding.

[0022] First, prepreg layup is carried out in wishbone lower mold 32 (using Toray TORAYA prepreg, grade P3252S-12 / 33, which is ±60° two-layer unidirectional fabric), and the layup method is according to the pre-designed layup method. layer structure, because the front fork itself is a special-shaped structure, and its different positions have d...

Abstract

The invention discloses an emulsion liner auxiliary pre-impregnating mould pressing prepared integrated front fork mould and a method thereof, which are fit for manufacturing the front fork of a bicycle with compound materials. The method comprises the steps of: preparing two detachable combined two sets of mould devices, wherein the first set of mould device is used for paving a fork bone layer and the second set of mould device is used for paving left and right two hooks, after finishing the paving process, placing an emulsion liner in a fork bone lower mould, simultaneously forming on a machine frame after combining the moulds, and acquiring an integrated front fork product after cooling and de-molding. Compared with a sectional front fork, the integrated front fork has better consecutiveness, requires no serials process like post-gluing process in the manufacturing process of the sectional front fork, overcomes the shortcomings of the sectional front fork that the mechanical property at the joint between the hook and the fork bone is different and the size deviation easily occurs by using the integrated structure, and has excellent size stability and mechanical property.

Description

technical field [0001] The invention relates to a composite material molding process, in particular to a mold for preparing an integrated front fork by means of latex liner auxiliary prepreg molding and a method for preparing the integrated front fork by using the mold. Background technique [0002] Compared with traditional metal materials, composite materials have many excellent properties, such as light weight, high specific strength, good dimensional stability, and excellent chemical stability. Therefore, its application range is wider and its manufacturing process is becoming more mature. According to the end use and structure of the product, many molding processes have emerged as the times require. [0003] The front fork of the bicycle is connected to the frame through the front fork assembly with two sets of ball bearings. The front fork can rotate flexibly on the frame and can bear certain gravity and impact. Currently, composite material bicycles on the market are ...
