In mold design, in order to shorten the molding cycle of the mold, improve production efficiency, and ensure product quality, mold cooling is essential. The commonly used media for mold cooling include cold water, warm water, oil temperature, etc., not all molds need to be designed for cooling For water transportation, some molds also need to be heated. This is because the molding process of each plastic material is different, resulting in the temperature of the mold being different. Here are some water transportation design standards to share with you, and I hope to bring you some Enlightenment:
1. The design principle of cooling system: large mold cold glue position; small mold cold inner mold. More than 4 (mm) away from the row position insert or penetration position at the water side. 8～10, 10～12, 12～16 (mm) above the edge of the glue position when transporting water. 3, 4, 5 (mm) from the side of the water transport to the thimble, inserts, and screws (mm) from the side of the steel material: M6, M8, 11mm; M10, M12, 14mm. The distance between two parallel water transport centers is ≥25mm.
