Maze conformal cooling method and structure of mold
The invention provides a maze conformal cooling method and structure of a mold, and aims to solve the problem that the conventional mold cooling method cannot meet efficient and uniform cooling requirement of a complex mold. Compared with three traditional mold cooling method including a straight hole flow channel, a built-in bent pipe flow channel and a common tubular shape follow-up flow channel, the maze conformal cooling method is high in cooling efficiency and good in cooling effect. According to the structure, a hollow layer nearly parallel to the inner surface of a cavity is arranged in the position, having certain thickness distance from the cavity, in the mold, a maze type partition wall is arranged in the hollow layer, and a cooling medium flows in a channel formed by partition wall gapes in a cooling layer. The maze conformal cooling method and the structure of the mold have the advantages that the cooling state of the cooling medium in the gaps of the maze type partition wall is turbulence, and the contact area between the cooling medium and the mold is increased, so that the cooing efficiency is high, the service life of the mold is long, an injection molding process period is shortened, and the injection molding manufacturing cost is reduced. A 3-dimensional laser printing technology is adopted to directly manufacture the mold with the layered maze flow channel conformal cooling structure, components in the mold are uniform, the molding process is simple, the mold manufacturing period is short, and the mold manufacturing cost is low.
