[0002] As we all know, with the continuous development of the automobile industry and the advancement of interior parts production technology, injection molding of automobile interior parts has become one of the core processes in large-scale production. Injection molding technology is widely used in the manufacturing process of automobile interior parts, especially in the mass production of dashboards, door panels, seat parts, etc. The performance of the injection molding barrel, as the core component of the injection molding machine, has an important influence on molding quality, production efficiency and energy consumption. In the injection molding production process of automobile interior parts, cooling efficiency is one of the key factors affecting product quality and production efficiency. If the cooling is uneven or the cooling time is too long, it will cause quality problems such as deformation and cracking of the injection molded parts.

[0003] After searching, a Chinese patent discloses a simplified injection molding machine that can heat evenly and cool quickly. Its application publication number is CN208827044U. This patent realizes the rapid heating and cooling operation of the inner cylinder by setting up a cold oil pipe, a hot oil pipe, a first row of oil pipes and a second row of oil pipes, and adopts the method of separately injecting cold oil and hot oil. The temperature detector can monitor the oil temperature at any time, the liquid level rod can monitor the oil volume, and the steam pipe can remove the steam generated when the cold and hot oils are alternately used. Therefore, this device has a reasonable structure and is easy to use. It allows the inner cylinder to be fully immersed in the heat transfer oil, so that the inner cylinder can be heated evenly, thereby ensuring that the injection molding raw materials are heated evenly, and improving the heating and cooling speed of the injection molding machine.

[0004] During the production process of automotive interior parts, the heating and cooling efficiency of the injection molding barrel directly affects the injection molding effect. The problem with the prior art is that the existing injection molding barrel is cooled by injecting cold oil and hot oil, but the internal hot oil and cold oil cannot be completely extracted and replaced quickly, resulting in the inability to quickly cool the injection molding barrel.
