Rigid urethane foam moulded foaming device and method for foaming using same

The invention relates to a rigid urethane foam mould foaming device and a method for foaming using the same, which can effectively reduce air lock during forming, foaming cavities and surface cavities. The rigid urethane foam mould foaming device comprises a forming mould which is provided with an exhaust pipe and is also internally provided with accessory material, wherein the accessory materialis provided with an air passage, and a ventilation hole communicated with the air passage is arranged on the surface of the accessory material; when the accessory material bears negative pressure, the air passage can keep smooth; the air passage is communicated with the exhaust pipe; and air in the foaming mould enters the accessory material by the ventilation hole and is discharged by the exhaust pipe. The method for foaming with the rigid urethane foam mould foaming device is as follows: urethane foaming material is injected in the cavity of the foaming mould, a negative pressure generator communicated with the exha
