A mold device for a bicycle wheel hub

Abstract

The invention discloses a mold device for a bicycle hub. The invention includes a base, a supporting column is fixedly installed on one side of the top of the base, a feeding device is fixedly installed on the top of the supporting column, the feeding device includes a fixing frame, a driving motor, a first lead screw and a mounting block, and a driving device is fixedly installed on one side of the outer wall of the fixing frame. The motor, the output shaft side of the driving motor is fixedly connected with the first lead screw, the two sides of the inner wall of the fixed frame are provided with sliding grooves, one side of the sliding groove is slidably installed with a mounting block, the first lead screw runs through one side of the mounting block, and the mounting block and the second The contact part of the two lead screws is provided with a number of balls, the inner side of the mounting block is provided with a feeding barrel, and the bottom of the mounting block is provided with a hub mold frame on the side away from the drive motor. The mold device of the bicycle hub has the advantages of simple structure, low cost, high efficiency and high degree of automation, 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
