Description

Technical Field

[0001] The invention relates to the field of ice skate processing, and in particular to a mold for molding a rear tube end piece of an ice skate and a molding process thereof. Background Art

[0002] The ice blade is a steel blade-shaped object installed under the ice skates. The ice that the ice blade contacts melts into water, which reduces the friction between the ice blade and the ice, making it easier for the ice skates to slide. The ice blade and the ice skates are connected by a front support and a rear support. In the existing technology, the rear support is processed by a stretching process, which has low working efficiency and cannot guarantee the quality. Summary of the invention

[0020] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] 1. In the present invention, by setting a first mold and a second mold, the first mold can press the trimming sheet from top to bottom, so that the two sides of the trimming sheet are bent downward, and surround the outside of the first plug core to be preformed into a tubular structure, and then the second mold presses the preset pipe fitting from both sides to surround the outside of the second plug core, thereby trimming it into a target pipe fitting that meets the requirements. It has a simple structure and is easy to operate, which ensures the quality of the product and improves the production efficiency of the product. BRIEF DESCRIPTION OF THE DRAWINGS
