Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a high-pressure solidification casting apparatus used for manufacturing fiber-reinforced composite members. The present invention relates to an improvement in uniformly filling a fiber molded body disposed in a cavity by applying pressure.

Conventionally, this type of equipment has a pressure punch to pressurize the molten metal and an ejector pin to prevent the fiber-reinforced composite member from protruding from the molten metal. Since this is done by lowering the height of the steps, the entire device becomes larger in order to maintain the C'L space between the step heights, and the installation cost is also high, making it uneconomical.

The present invention is based on the following points, and it is possible to reduce the size of the entire device 6 by making it possible to raise and lower the bunch and the ejector bin, and to improve the economical efficiency.
