Mold device for bicycle hub

Abstract

The invention discloses a mold device for a bicycle hub. The mold device comprises a base. A supporting column is fixedly mounted on one side of the top end of the base, a feeding device is fixedly mounted at the top end of the supporting column and comprises a fixing frame, a driving motor, a first lead screw and a mounting block. The driving motor is fixedly mounted on one side of the outer wall of the fixing frame, and the first lead screw is fixedly connected to one side of an output shaft of the driving motor. Sliding grooves are formed in the two sides of the inner wall of the fixing frame, the mounting block is mounted on one sides of the sliding grooves in a sliding manner, the first lead screw penetrates through one side of the mounting block, a plurality of balls are arranged on the contact portions of the mounting block and second lead screws, a feeding barrel is arranged on one side of the mounting block, and a hub mold frame is arranged at the bottom of the side, away from the driving motor, of the mounting block. The mold device for the bicycle hub has the advantages of being simple in structure, low in cost, high in efficiency and high in automation degree, and can effectively solve the problems in the background technology.

Description

technical field [0001] The invention relates to the technical field of bicycle hub production, in particular to a mold device for a bicycle hub. Background technique [0002] Cycling has become a very popular competitive sport among amateurs and professional athletes, and has many advantages such as environmental protection and emission reduction, easy to use and green environmental protection. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle, as well as the wheels of the bicycle. One of the most important aspects of a bicycle is the rotation of the wheels relative to the bicycle frame. Therefore, it is important to construct a wheel that is inexpensive and easy to assemble, while maintaining good performance. The hub shaft of the integrated wheel is provided with an installation cavity for installing the brake assembly, and the spokes and the hub are die-cast integ...

Problems solved by technology

[0003] Most of the existing integrated bicycle wheels use the gravity casting method to pour the aluminum alloy solution into the mold by gravity. After forming, it is processed and polished by a lathe to complete the production. Low, and in the process of manufacturing the die-casting mold for the bicycle hub, due to the inaccurate feeding, it is easy to produce defective products, which affects the production efficiency. Broken needles, so to improve this, a mold device for bicycle hubs is proposed
