Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a toy injection mold with a multi-channel cooling water channel structure. Background Art

[0002] In the production process of plastic products, mold injection molding is required. In the process of mold injection molding, cooling becomes an extremely important link, and excellent cooling water design directly affects the performance of plastic products and technical characteristics such as product purity. Therefore, the design of the cooling water channel should ensure that the medium flowing in the water channel can fully absorb the heat conducted during the molding of the plastic parts, so that the temperature of the mold molding surface is stably maintained within the required temperature range, and the cooling medium should flow smoothly in the water channel. However, a single-channel cooling water structure may result in a slow water flow rate in the cooling pipe, resulting in low cooling efficiency. For example, a Chinese patent discloses a "cooling water channel structure for an injection mold core", and its application number is: "202020555681.9". By setting up multiple cooling water channels, the circulation of cooling water in the mold core can be increased to avoid pipe blockage, while increasing the cooling area and thereby improving its cooling effect. However, it has no protective structure, which may cause harm to the staff during the injection molding process, and the multiple water channels of the device cannot be controlled separately to meet the production needs of different injection molds.
