Description

Technical Field

[0001] The invention relates to a saddle, and to the fields of bicycles, motorcycles or electric vehicles, and in particular to a saddle bottom plate manufacturing method, a mold, a saddle bottom plate and a saddle. Background Art

[0002] my country has a large population. Due to economic factors, traffic conditions and other factors, most people choose bicycles as their means of transportation. Bicycles are also popular among people because of their light weight and low price. Therefore, my country is known as a bicycle power.

[0003] A bicycle, also known as a bike or a bicycle, is usually a small two-wheeled land vehicle. People ride on it and use pedals as power. It is a green and environmentally friendly means of transportation.

[0004] The bicycle is one of the most successful human-powered machines invented by mankind. It is a complex machine composed of many simple machines. With the development of society, the requirements for the research and development and technical expertise of bicycle products are getting higher and higher.

[0005] The saddle is installed on the bicycle saddle pipe through the saddle beam, which is an indispensable and important component for providing sitting support. However, at present, the installation structure of the saddle beam and the bottom plate is to firstly inject a bottom plate with a top saddle beam receiving groove and two rear end saddle beam receiving grooves, and then press the saddle beam into the top saddle beam receiving groove and the two rear end saddle beam receiving grooves through a pressure mechanism. This method takes a long time to work and is complicated to operate. In addition, after the saddle beam is clamped with the top saddle beam receiving groove and the two rear end saddle beam receiving grooves, there is still a gap in the groove, which makes the product stability poor. Summary of the invention

The movable mold is provided with an injection cavity for injecting the saddle beam accommodating part at the top end of the front end of the bottom plate and the saddle beam accommodating parts at the tail ends of both sides of the lower part of the bottom plate body.

[0017] The saddle beam clamping mechanism comprises a moving clamping block and a plurality of fixed saddle beam brackets. The moving clamping block is interspersed with a moving guide column. The moving clamping block moves along the moving guide column to be clamped or separated from the moving mold.

[0018] The moving clamping blocks are two and are respectively arranged on both sides of the moving mold.

[0019] The fixed saddle beam bracket comprises a top fixing bracket for fixing the top of the saddle beam and two side fixing brackets on both sides of the fixed saddle beam. When the saddle beam is fixed on the fixed saddle beam bracket, its top end and tail end extend into the fixed injection molding cavity.
