Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fiber-reinforced composite molding device including a discharge supporting part,

The present invention relates to a molding apparatus for molding a fiber-reinforced composite material molding, and more particularly, to a molding apparatus for molding a fiber-reinforced composite material molding, which comprises a discharge supporting portion and is capable of discharging excess resin generated during a molding process, To a molding apparatus.

In general, a prepreg product widely used for producing a composite fiber reinforced product has a form in which a reinforcing fiber is impregnated with a resin. In order to produce a fiber composite reinforced product, a plurality of prepregs are laminated in a predetermined shape, and they are molded by applying heat and pressure.

As a result, a plurality of prepregs are compressed. In this process, the excess of the resin impregnated in the prepreg is released from the molded article.

At this time, the resin needs to be smoothly discharged from the molding space in which the prepreg molding is molded. However, since the conventional molding apparatus is not equipped with such a discharge structure, sufficient pressure can not be applied to the molding, Which is a problem in that the temperature is greatly decreased.

Therefore, a method for solving such problems is required.

The first mold 100 and the second mold 200 are formed so that at least one side thereof is movable, and heat and pressure are applied to form a molded product of the fiber-reinforced composite material accommodated in the molding space.

In the present embodiment, the first mold 100 is located at a lower portion, the second mold 200 is located at an upper portion, and the second mold 200 is formed to be movable up and down.

In this embodiment, the fiber-reinforced composite material is a prepreg. However, it is needless to say that various types of fiber reinforced composites can be used.

Further, the prepreg molding is a leaf spring, and thus the molding space 110 is formed long in the lateral direction so as to correspond to the shape of the leaf spring. Further, the molding space 110 is formed to be inclined downward in both directions so as to correspond to the shape of the final leaf spring.

In the present embodiment, the second mold 200 includes a pressing portion 210 protruding in a shape corresponding to the molding space 110 and pressing the molded prepreg received in the molding space 110. Accordingly, in the present embodiment, the pressing portion 210 is formed to be inclined downward in both directions so as to correspond to the molding space 110.

4, the prepreg molding 10 having a flat shape is placed in the molding space 110, and then the prepreg molding 10 is compressed by lowering the second mold 200 as shown in FIG. 5 The final shape of the bent leaf spring is produced.

Referring to FIG. 2 again, the first mold 100 further includes an ejection support 120 and an eject pin 130 in this embodiment. The eject pin 130 will be described later, and the ejection support 120 will be described first.

The discharge support part 120 is provided in the molding space 110 to support the prepreg molding and to communicate the molding space 110 with the outside so that the excess resin generated in the molding process of the prepreg molding is supplied to the outside .

In this embodiment, the discharge support part 120 is provided on both sides of the molding space 110 according to the shape of the leaf spring to be manufactured. That is, the discharge support part 120 supports both sides of the prepreg molding in the molding process of the leaf spring.
