Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane casting, in particular to a polyurethane casting and molding device for producing aviation plates. Background Art

[0002] Existing aviation panels often use polyurethane in the production process, and polyurethane needs to be cast in a molding device in the production process so that it can be made into a desired shape.

[0003] A Chinese patent (Announcement No.: CN214872102U) discloses a polyurethane casting and molding device for the production of aviation panels, including a rotatable casting mold, a cover frame, and an exhaust structure. The upper end of the casting mold is accommodated in the cover frame and is slidably connected to the inner surface of the cover frame. The cover frame is also provided with a sealing ring, the outer circumference of the sealing ring is fixedly connected to the inner circumference of the cover frame, and the sealing ring rests on the upper surface of the casting mold. The utility model realizes the sealing between the cover frame and the casting mold by arranging a cover frame at the upper end of the casting mold and arranging a sealing ring in the cover frame, and cooperates with the sealing ring to seal the cover frame and the casting mold. The exhaust structure on the cover frame generates negative pressure in the cover frame when the casting mold drives the cover frame to rotate, and cooperates with the rotating polyurethane to quickly break up the bubbles inside and flow upward. At the same time, the speed of the bubbles flowing upward is accelerated under the action of negative pressure, so that the gas in the bubbles enters the cover frame as soon as possible, so as to achieve the purpose of removing bubbles. The bubble removal effect is significant and the removal is comprehensive. However, the casting mold of the device rotates on the upper surface of the workbench, which causes obvious friction between the casting mold and the workbench, which easily accelerates the wear of the casting mold and has a short service life.

[0004] In order to solve the above problems, we have made improvements and proposed a polyurethane casting and molding device for the production of aviation panels. Utility Model Content
