The utility model provides a pouring system with a buffer structure, and belongs to the technical field of injection molds. The technical problem that an existing thick plastic product is prone to generating injection molding defects such as flow marks is solved. The pouring system with the buffer structure comprises a main runner, a sub-runner, a buffer pipe and a pouring gate which are communicated in sequence, the sub-runner is in a circular tube shape, and is characterized in that the buffer pipe and the pouring gate are both in a flat tube shape, the buffer pipe is vertically arranged, the lower end of the buffer pipe is connected with the sub-runner, and the upper end of the buffer pipe is connected with the pouring gate. According to the utility model, the impact of the molten material on a molded product is relieved, the temperature uniformity of the molten material when entering the cavity is improved, and the problem of flow marks of thicker plastic products is solved. 本实用新型提供了一种带有缓冲结构的浇注系统，属于注塑模具技术
