Abstract

The invention discloses a rotational molding die, and a rotational molding method. According to the rotational molding die, a first part mold cavity is arranged in an upper thermal conductive template; a second part mold core is arranged in a lower thermal conductive template; each mold cavity assembly comprises a mold cover and a second part mold cavity detachably connected with the lower part of the mold cover; when a first part is inserted into a mold cover, a sealed second part die cavity is formed by the first part, the mold cover, and a corresponding second part mold cavity; the movable tray is connected with the lower thermal conductive template, and is fixedly provided with a plurality of the mold cavity assemblies, and the first parts are inserted into the mold cavity assemblies. According to the rotational molding method, rotational molding of second parts is realized, and synchronous automatic bonding of the second parts with corresponding first parts can be realized, so that subsequent bonding assembling procedures are avoided, adverse influences of binders on products are avoided, the mold cavity assemblies containing the products can be moved out of the rotational molding die for cooling at the same time, the temperature of the rotational molding die is maintained to be a rotational molding temperature, repeat temperature increasing after die cooling is avoided, molding period is shortened greatly, production cost is reduced, and production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of rotational molding, in particular to a rotational molding mold for an anesthesia breathing mask and a rotational molding process method. Background technique [0002] Rotational molding is a process for forming hollow plastic products, called rotational molding or rotational molding. Rotary molding is to add resin powder or resin solution into the mold, heat the mold and make it rotate continuously along two mutually perpendicular axes, the resin in the mold melts and is evenly coated and melted and adhered to the mold under the action of gravity and heat The inner surface is formed into the desired shape, and the workpiece is obtained after cooling. [0003] In actual product production, when the parts after rotational molding are to be assembled and connected with other parts, they are usually assembled manually by glue or solvent bonding. [0004] For example, in the manufacturing process of medical ...
