Disclosed are a method and device for making a silastic cupping appliance; the device comprises: a nozzle (12), an internal mould core (4), a separable slide (7) and blowing-demoulding unit (6); the separable slide (7) is composed of at least two separable slide blocks, the separable slide (7) and the internal mold core (4) form a mould cavity (1) between them for the formation of the silastic cupping appliance; one end of the nozzle (12) is connected with a channel for the input of a liquid silastic material and the other end is connected with the mould cavity (1); the blowing-demoulding unit (6) is connected through to the mould cavity (1) via a blow duct opening(23) which is set at the junction of the internal mould core (4) and the mould cavity (1). The method comprises the following steps: preheating, cooling for protection, feeding material, vulcanizing and demoulding. The method and device take liquid silicone rubber as the raw material and employ a silicone rubber injection-vulcanization moulding technique, which can produce a silastic 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 and there is no need for a dismounting washing unit during demoulding. |
