Embodiment

[0044] This embodiment is a mold and a molding method for a certain type of large curvature, open, and thin-walled structure composite material projectile. The mold adopts a semi-closed, single-cavity, side-pressurized structure, including punches, dies, upper covers, side blocks, side sliders, lifting rings and fastening bolts. The mold structure is as follows:

[0045] The die has a rectangular structure, with a sloped semi-circular groove in the middle, and a through hole in the groove, which is integrally matched with the punch, and rings are installed on both sides. Quantity 1 piece.

[0046] The punch is a combined structure of a semi-circular boss and a rectangular bottom plate. There are threaded holes on the top surface and both ends of the boss for locking and fixing the screws on the upper cover. There are steps on the semi-circular boss for Installation and positioning of the upper cover. Threaded holes are provided on the bottom plate for locking and fixing wit...

Abstract

The invention provides a forming mold and method of a large-curvature open thin-walled structure composite. The forming mold is of a half-closed type single-cavity lateral-pressurization structure andcomprises a male mold, a female mold, an upper cover plate, lateral stop blocks, lateral sliding blocks, lifting rings and fastening bolts. By the adoption of the forming mold and method of the large-curvature open thin-walled structure composite, the quality problems of product deformation, dimension deviation, surface defects and the like which are prone to happen in the mold pressing process of a large-curvature open thin-walled composite product are solved, the mold structure is light, simplified, economical and durable, the forming mold is suitable for various pressure devices and achieves one-off formation of a large-curvature open thin-walled structure, the work amount of post-treatment is small, and the yield is high.

Description

technical field [0001] The invention belongs to a novel molding die for composite material products and a molding method thereof, in particular to a large curvature, open, thin-walled composite molding mold and a molding method thereof. Background technique [0002] The product is a large curvature, open, thin-walled structure, such as figure 1 , Using chopped fiber premix molding, the product requires uniform resin content, smooth surface, no flash burrs, no holes, no delamination and other quality problems. Due to the special structure of the product, the aspect ratio of its cross section is too large. When designing the mold structure, it is necessary to comprehensively consider the thermal and mechanical properties of the mold material, optimize the mold structure, and ensure that the mold will not Product damage occurs, so that the mold design has the characteristics of light weight, simple structure, perfect function, economical and durable. [0003] This product ado...
