Description

Technical Field

[0001] The utility model relates to the technical field of billiard ball manufacturing equipment, in particular to a novel billiard ball mold set. Background Art

[0002] Billiards, a popular ball sport, has a long history. Originally, billiard balls were made of brass and wood, but later switched to ivory due to material properties. With advances in technology and materials science, billiard balls are now mostly made of resin, available in a wide variety of styles. During the billiard ball manufacturing process, numbers, patterns, and other designs are often added to the surface to meet personalized needs. This is typically achieved using molds with lettering. Specifically, the lettering is injection molded first, followed by the billiard ball, completing the basic prototype. However, some billiard balls currently on the market face certain technical limitations and cost considerations during production. Although the billiard balls and lettering are mostly made of resin, in some cases, foreign materials are needed to support and secure the lettering within the mold to ensure that it does not shift during the injection molding process and achieve the desired appearance.

[0003] Some manufacturers use specially shaped plastic blocks to support the code particles to prevent them from shifting during the injection molding process. However, this method will increase production costs and cause some technical complexity in subsequent processes, thus affecting the overall quality and performance of the billiard balls. For this reason, a new billiard ball mold set is proposed. Utility Model Content
