Disclosed are a method and device for making a silicone rubber cupping appliance. The device includes: a nozzle, an internal mould core, a separable slide and blowing-demoulding unit. The separable slide includes at least two separable slide blocks, the separable slide and the internal mould core from a mould cavity between them for the formation of the silicone rubber cupping appliance. One end of the nozzle is connected to a channel for transporting liquid silicone rubber material and the other end is connected to the mould cavity. The blowing-demoulding unit is connected through the mould cavity via a blow duct opening which is set at the contact surface of the internal mould core and the mould cavity. The method comprises the following steps: preheating, cooling for protection, feeding material, vulmayizing and demoulding. The method and device take liquid silicone rubber as the raw material and employ a silicone rubber injection-vulcanization moulding technique, which may product a silicone rubber cupping appliance with high elasticity, high transparency and complex shape. The method and device are simple in procedure, wholly automatic, high in production efficiency, simple and fast in demoulding. There is no need for a dismounting washing unit during demoulding. |
