Abstract

The invention discloses a mold structure for a bicycle hub and relates to the technical field of bicycle hub production. The mold structure comprises an upper mold plate, a lower mold plate and an ejection mechanism. By the adoption of the technical scheme, in the ejection mechanism, an ejection sleeve and a fixing insert are arranged in a matched manner, the upper end of the ejection sleeve extends into the internal center of a flow division cone, ejecting and mold releasing are carried out on a hub shaft of an integration wheel of a bicycle formed in a compression cast manner, the contact area of ejection is large, the wheel can be effectively ejected, an ejection pin is replaced by the ejection sleeve, the service life of the ejection mechanism is prolonged, the risk of loss and breakage of the ejection pin is avoided, the cost is effectively saved, and the product quality is further improved.

Description

technical field [0001] The invention relates to the technical field of bicycle hub production, in particular to a mold structure for a bicycle hub. Background technique [0002] In today's society, bicycles are widely used in people's daily life as a means of transportation, and have many advantages such as environmental protection, emission reduction, convenient use, and environmental protection. [0003] The integrated bicycle wheel is mainly made of magnesium alloy, and the hub shaft and the hub are connected by multiple spokes. The structure is simple, the cost is low, and the forming effect is good. It is used to install the installation cavity of the brake assembly, and is integrally formed by die-casting with the spokes and the hub. [0004] In the prior art, in the design of the die-casting mold for the integrated bicycle wheel, the structure of the hub shaft of the integrated bicycle wheel is thick and thick, and ejection of the integrated bicycle wheel in the form...
