Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0020] Such as figure 1 , a soft mold for composite material products, comprising a core layer 1 and a surface layer 2 of plastic material, the surface layer and the core layer are closely attached, and the surface layer covers the core layer. The material of the surface layer is polypropylene film, one side is smooth and the other side is sticky, and the sticky side is in contact with the core layer.

[0021] The manufacturing method of the soft mold includes (1) taking an appropriate amount of core layer according to the demand: the width of the core layer is the perimeter of the R angle + (0~4) mm, the length of the core layer is the length of the composite material product + (0~4) mm, if the soft mold When the die is used in conjunction with the equalizing plate, the thi...

Abstract

The invention discloses a soft die for a composite product and a manufacturing method of the soft die. The soft die comprises a core layer made of a plastic material and a surface layer; the surface layer is tightly fitted to the core layer; the core layer is covered by the surface layer; and the surface layer is made of a polypropylene film, one surface of the surface layer is smooth and clean, the other surface of the surface layer is viscous, and the viscous surface is in contact with the core layer. The soft die disclosed by the invention is relatively soft, has plasticity and a certain deformability under the action of an external force before being shaped and is reduced in plasticity and improved on elasticity after being shaped so as to be made to be various shapes and be widely applied to pressure transfer in places such as an angle R, an angle V and an angle U in the vacuum curing process of the composite product.

Description

technical field [0001] The invention relates to a soft mold and a manufacturing method thereof. Background technique [0002] At present, in the vacuum-assisted molding process of composite products, because the R angle of the female mold is easy to bridge and cannot be under pressure, the R angle of the product is easy to be loose or rich in resin, and the R angle of the male mold is unevenly stressed (too large), resulting in the R angle of the product Problems such as too thin thickness affect product quality. Contents of the invention [0003] The purpose of the present invention is to provide a soft mold and its manufacturing method to solve the problems of loose R angle, resin-rich or too thin thickness caused by bridging or excessive force in the vacuum-assisted forming process of composite products. [0004] The concrete scheme that the present invention solves its technical problem is: [0005] A soft mold for composite products, including a core layer and a sur...
