[0007] Preferably, the lower mould side wall is provided with a plurality of holes, a plurality of holes are annularly arranged, and the holes are communicated with the cooling groove.
[0008] Preferably, the lower end of the movable plate is fixedly connected with a spring, and the end of the spring is fixedly connected with the inner bottom of the cavity.
[0009] Preferably, the lower end of the movable plate is fixedly connected with a stop column, the lower end of the stop column is attached to the inner bottom of the cavity, and the spring is sleeved outside the stop column.
[0010] Preferably, the upper mould is provided with a cavity in the inside, a plurality of connecting holes are annularly arranged and provided in the inside of the upper mould, one end of the connecting hole is communicated with the cavity, and the other end of the connecting hole is communicated with the slot.
[0011] Preferably, a pipe is fixedly connected to the upper end of the upper mold, and the output end of the pipe is connected to the cavity.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. The external pump delivers cooling airflow to the interior of the cavity through pipes. The cooling airflow flows into the slot through multiple connection holes. The cooling airflow inside the slot flows into the cooling tank, where it exchanges heat between the interior of the lower mold and the interior of the upper mold. Then, the airflow that has exchanged heat inside the cooling tank is discharged through multiple holes, thereby cooling the raw material inside the molding tank. This allows the raw material to be quickly molded into the required dustproof ring. The cooling airflow quickly removes heat from the mold and the injection material, accelerating the cooling and solidification process of the raw material, thereby shortening the production cycle and improving production efficiency.
[0014] 2. After the dust ring cools and solidifies, the lower mold separates from the upper mold for demolding. The elasticity of the spring pushes the movable plate upward, causing the movable plate located in the lower section of the cavity to slide upward automatically. The movable plate drives multiple ejector pins and pillars to slide upward. The ejector pins slide from inside the lower mold to inside the forming groove, thereby pushing the lower end of the dust ring upward, causing the dust ring to separate from the forming groove. This facilitates demolding of the dust ring. By having the ejector pins slide from inside the lower mold to inside the forming groove, they push the lower end of the dust ring upward evenly and steadily, avoiding scratches, deformation, or damage that may be caused by manual demolding, thus ensuring the integrity and quality of the dust ring.
