Description

Technical Field

[0001] The utility model mainly relates to the technical field of composite vulcanization molds, in particular to a vulcanization mold body of a rubber and metal composite air nozzle. Background Art

[0002] The rubber and metal composite air inlet nozzle is a de-icing airbag product used on a certain type of aircraft. The rubber and metal composite air inlet nozzle is bonded to the back of the de-icing airbag product and attached to the aircraft wing. The air inlet nozzle is connected to the inflation device through the reserved opening on the wing. Since the de-icing airbag product is inflated and deflated more than 20,000 times, the air inlet nozzle is subjected to positive and negative pressure changes, and is subjected to high and low temperature changes, salt spray erosion, mold, collision, friction and other harsh working conditions during the flight of the aircraft, so the quality requirements for the air inlet nozzle are very strict. The air inlet nozzle is composed of rubber and metal air inlet nozzles. In order to adapt to the reserved opening on the wing and connect with the inflation device, the air inlet nozzle is designed as a 120° curved structure. The rubber part is located at the tail of the air inlet nozzle. The width of the vulcanized composite interface is only 7mm, and its surface is coated to meet the normal use in long-term harsh environments. The product has a complex structure, strict use requirements, and the surface coating needs to be protected.

[0003] In the known technology, a vulcanization mold is used to first fix the metal air inlet nozzle, a rubber sheet is laid on the reserved space of the rubber part, and vulcanization is performed after pressure is applied by various components of the vulcanization mold. Utility Model Content

[0004] The utility model mainly provides a rubber and metal composite air inlet nozzle vulcanization mold to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical solution to solve the above technical problems: it comprises an upper mold and a lower mold, wherein the upper mold and the lower mold clamp a cylindrical mold of an inner mold assembly, and a split mold is provided on the inner mold assembly, and the upper mold, the split mold, and the lower mold constitute a vulcanization mold.

[0006] Furthermore, the split mold consists of two split molds.

[0007] Furthermore, the split mold is provided with a metal air inlet nozzle fixed cavity.

[0008] Furthermore, the mold core is in contact with the metal air inlet nozzle and the upper mold.

[0009] Furthermore, the upper mold and the lower mold are both circular.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model realizes that the mechanical cooperation of the upper mold and the lower mold to the split mold makes the split mold radially contact and pressurize, thereby ensuring that the position of the metal air inlet nozzle is fixed and that the coating on the outer surface of the metal air inlet nozzle is not damaged by the mold, thereby playing a protective role; the mechanical cooperation of the upper mold and the split mold with the mold core makes the mold core axially contact and pressurize, thereby ensuring that the rubber and the metal air inlet nozzle are compositely vulcanized so that a vent is left, thus solving the problem of composite vulcanization of special-shaped metal air inlet nozzles and rubber, ensuring the density of rubber vulcanization, avoiding damage to the surface of the metal air inlet nozzle caused by the mold due to pressure, and improving the qualified rate of the composite parts of the rubber and metal air inlet nozzles.
