Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt machines, in particular to a hot-melt machine for lifebuoy plastics. Background Art

[0002] Lifebuoys are usually made of lightweight materials with a low specific gravity, such as rubber, wrapped in canvas on the outside and filled with air on the inside. They are mainly used for water lifesaving or for swimming practice.

[0003] At present, plastic lifebuoys generally adopt a split injection molding scheme, the principle of which is to first use two injection molds to thermoplastically mold the upper and lower parts of the lifebuoy respectively, and then use manual or semi-automatic machinery to hot-melt weld the upper and lower parts of the lifebuoy to achieve small-scale quantitative production of lifebuoys; however, the two halves of the lifebuoy need to be cooled and molded first (also to avoid scalding the operators with high-temperature lifebuoys), and then heated up for hot-melt welding, which not only wastes hot-melt heat, but also prolongs production time and reduces production efficiency; in addition, lifebuoys mostly use blow-molded shells, and the body uses environmentally unfriendly polyurethane foaming agents as fillers, which not only pollute the environment during production, but also harm human health, and pollute water sources after being oxidized when put on the market.

[0004] Therefore, how to design a lifebuoy injection molding machine with low heat usage and high production efficiency is a problem that technicians in this field need to solve urgently. Utility Model Content
