Processing mechanism and processing method of main body component of bicycle

Abstract

The invention provides a processing mechanism and a processing method of a main body component of a bicycle. The processing mechanism is characterized in that a water needle for injecting water into a cavity is arranged at a main cavity channel of the cavity of a mold, wherein the front part of the water needle is inserted into the cavity, and a material overflowing cavity for containing overflowed materials is communicated with the other end, opposite to the direction of the water needle, of the main cavity channel through an overflowing pipe; a closeable glue feeding member for injecting glue materials is further arranged at the side wall of the main cavity channel. According to the processing mechanism and the processing method, a water-assisted molding process is introduced into an injection molding process, the two processes are organically combined, and high pressure water is utilized for driving the redundant glue materials in a product out of the cavity, so that the component product is very rapid to cool, and pressure maintaining and cooling processes in the normal injection molding process can be omitted; furthermore, the product can be molded at a time, so that the efficiency is greatly improved, meanwhile, the strength is guaranteed, the wall thickness of the component is very uniform, the shape precision is greatly improved as well, the shapes of bicycle components such as bicycle frames having more braches are diversely designed, and the weights of the bicycle components are light.

Description

technical field [0001] The invention relates to a processing mechanism for a bicycle main body component, especially a processing mechanism that uses injection molding combined with water-assisted molding, and also provides a corresponding processing method. Background technique [0002] The frame, front fork, handlebar, seat tube, etc. are the main components that make up the bicycle. The manufacturing materials of these components have been developed from traditional steel and aluminum to polymer composite materials such as glass fiber and carbon fiber, making bicycles are developing towards lightweight. However, due to the craftsmanship, the production of bicycles still remains between manual and semi-mechanical. Therefore, the production efficiency of the bicycle is low, and the processing cost is high. For example, a bicycle frame production factory with 200 employees can only produce 3,000 frames a month; the material cost of a carbon fiber frame is 400 yuan, but the...

AI Technical Summary

Problems solved by technology

The disadvantages of this design are: 1. The strength of the bicycle will be reduced; 2. Multiple sets of injection molds are required for production, which increases the cost

3. It is necessary to assemble the two halves of the product together, which increases the labor cost

4. It is necessary to deal with the gap between the assembly screw hole and the joint of the product, which again increases the labor cost

This solution is similar to the first one, but the cost is too high and the later assembly is complicated

Productivity cannot be effectively improved

[0007] In fact, the above three solutions are all to solve a problem, that is, to make the body of each main component of the bicycle hollow, but they do not solve the problems of cost and productivity.
