Mold preheating device of double-color injection molding machine

The utility model relates to a mold preheating device of a double-color injection molding machine. The mold preheating device comprises a rack, a bottom plate, ground feet, side plates, a top cover, alimiting plate, a supporting plate, a supporting pipe, a blocking pipe, an air inducing assembly, an exhaust pipe, a front door plate, a rear door plate and a sealing assembly, heat emitted by the heating cabin of the double-color injection molding machine is used for preheating the mold, the temperature difference between the mold temperature and a molten material is reduced, the flowability ofthe molten material in the mold is improved, the injection molding quality is guaranteed, no extra energy is consumed, energy is saved, the environment is protected, and the use is simple and convenient. 本实用新型涉及一种双色注塑机的模具预加热装置，包括台架、底板、地脚、侧板、顶罩、限位板、托板、支撑管、档管、引风组件、排风管、前门板、后门板和封闭组件；本实用新型利用双色注塑机加热舱散发出来的热量来预先加热模具，缩小模具温度与熔融料的温差，提高了熔融料在模具中的流动性，保证了注塑质量，且不需要消耗额外能源，节能环保，使用简单方便。
