A method for producing a silicone rubber cupping appliance using a device comprising: a nozzle; an internal mould core; a separable slide comprising at least two separable slide blocks; and a blowing-demoulding unit; wherein a mould cavity used for moulding the silicone rubber cupping appliance is formed between the slide and the internal mould core; wherein one end of the nozzle is connected to a channel that transfers liquid silicone rubber material, another end of the nozzle is connected to the mould cavity; and wherein the blowing-demoulding unit is connected to the mould cavity through a blow duct opening which is set at a contact surface of the internal mould core and the mould cavity; characterized by the following steps: step 1) of preheating and cooling protection: heating the moulding zone which is at least formed by the slide, internal mould core and the mould cavity; at the same time cooling the channel that the liquid silicone rubber material must pass by and/or a zone surrounding the channel; step 2) of adding material injecting liquid silicone rubber material into the mould cavity; step 3) of vulcanizing: stopping adding material and keeping heat preserving for a duration of time; step 4) of demoulding: separating the separable slide, at the same time opening the blow duct opening, and blowing the moulded silicone rubber cupping appliance in the mould cavity by the blowing-demoulding unit for demoulding, wherein the step 4) further comprises: step 4.1): separating the separable slide at two sides along a direction lying vertical or approximately vertical to an axial of the mould cavity, causing an external mould surface of the silicone rubber cupping appliance in the mould cavity to be exposed in air; step 4.2): opening the blow duct opening in the blowing-demoulding unit, causing the blow duct opening of the blowing-demoulding unit to be connected to the mould cavity; and step 4.3) of blowing-demoulding: letting the high pressure gas enter between the internal mould surface of the mould cavity and a solidified silicone rubber cupping appliance through the blow duct opening, and blowing away the solidified silicone rubber cupping appliance from the internal mould surface; and wherein the method further comprises step 5): production in cycle: repeating steps 2) to 4). a nozzle; an internal mould core; a separable slide comprising at least two separable slide blocks; and a blowing-demoulding unit; wherein a mould cavity used for moulding the silicone rubber cupping appliance is formed between the slide and the internal mould core; wherein one end of the nozzle is connected to a channel that transfers liquid silicone rubber material, another end of the nozzle is connected to the mould cavity;
