This utility model provides a cage injection mold with a rapid preheating structure, comprising: a moving mold at the bottom of a fixed mold; a sprue sleeve passing through the center of the fixed mold on the side away from the moving mold; a mold core assembly positioned at the center of the fixed mold and the moving mold on the side close to each other; a hot runner heating module sleeved on the bottom of the sprue sleeve at the top; and a heating rod heating module passing through the center of the mold core assembly; and several junction boxes bolted to the side walls of the fixed mold and the moving mold. In the mold preheating process, based on heat conduction heating using a mold temperature controller, a hot runner heating module and a heating rod heating module are installed at the core of the mold. These are connected to a power plug via junction boxes to achieve electric heating at the core, which assists in rapid mold preheating and greatly improves processing efficiency. During injection, the temperature of the liquid plastic does not drop when it enters the molding cavity composed of the fixed mold core and the moving mold core, improving the quality of the injection molded parts. Furthermore, the injection runner can be diverted to allow one mold to process multiple injection molded parts simultaneously, improving production efficiency.
