In order to meet the mold temperature requirements of the injection process, a temperature control system is required to adjust the temperature of the mold. For injection molds for thermoplastics, the cooling system is primarily designed to cool the mold. The common method for mold cooling is to open a cooling water passage in the mold and use circulating cooling water to take away the heat of the mold. In addition to heating the mold, hot water or steam can be used in the cooling water passage, and electricity can be installed inside and around the mold. Heating element.
Fold molded parts
Molded parts refer to the various parts that make up the shape of the product, including moving molds, fixed molds and cavities, cores, forming rods, and exhaust ports. The molded part consists of a core and a die. The core forms the inner surface of the article and the die forms the outer surface of the article. After mold clamping, the core and cavity form the mold cavity. According to the process and manufacturing requirements, sometimes the core and the die are assembled from several pieces, sometimes made in one piece, and the inserts are only used in parts that are easily damaged and difficult to machine.
