Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a carbon fiber badminton racket injection mold. Background Technology

[0002] Badminton is a sport that can be played both indoors and outdoors. Depending on the number of participants, it can be divided into singles, doubles, and the emerging 3v3. A badminton racket consists of a racket face, shaft, handle, and the joint between the frame and shaft. In today's popular sports era, the demand for badminton rackets is increasing. Existing badminton rackets are usually manufactured in molds. After molding, the racket may get stuck in the mold and need to be manually removed or pried out with tools, which can easily damage the product and affect production efficiency. Most current technologies spray a release agent onto the mold before the carbon fiber raw material is put into the mold. A release agent needs to be sprayed after each processing, which also affects efficiency. Utility Model Content
