Description

Technical Field

[0002] A rubber vulcanizing injection molding machine, also known as a rubber injection vulcanizer, is a mechanical device that transforms raw rubber into rubber products with specific shapes and properties through high temperature, high pressure, and chemical reactions. It is primarily used for molding and vulcanizing rubber products such as soles, seals, and rubber hoses. The vacuum hood of a rubber vulcanizing injection molding machine is a crucial component in the vulcanization process. It is primarily used to evacuate rubber products during the vulcanization process to remove air bubbles and volatiles, improving vulcanization quality and product density.

[0003] Publication No. CN204414444U discloses a vacuum hood mechanism for a rubber vulcanizing injection molding machine. The vacuum hood comprises a fixed vacuum hood with a square cross-section and a movable vacuum hood. The fixed vacuum hood is fixedly mounted on the lower surface of the top seat of the rubber vulcanizing injection molding machine. The movable vacuum hood seals against the outer wall of the fixed vacuum hood. The peripheral wall of the fixed vacuum hood has a polished outer surface. Vacuum hood cylinders are fixedly mounted on both sides of the top seat, driving the movable vacuum hood to slide up and down using the fixed vacuum hood as a guide column. The fixed vacuum hood and the movable vacuum hood cooperate to form a vacuum hood chamber with a lower opening. The vacuum hood chamber cooperates with a sliding plate on the rubber vulcanizing injection molding machine to form a sealed vacuum chamber. This utility model has high vacuuming efficiency, can reduce vulcanization time, and improve product quality. It is highly versatile, has a wide range of applications, and provides a large sealing space.
