<p>In the present invention, provided is a squeeze pin device, which protrudes toward the inside of a molding space from a metallic mold, accordingly resolves air pores formed on the molded products in the molding space of the metallic mold. The squeeze pin device is installed in an installation space communicating with the molding space, and protrudes and operates by hydraulic pressure, thereby pressurizing the materials molded into the molding space. The device comprises: a squeeze pin which is installed in the installation space; an elastic member which elastically supports the squeeze pin to prevent the squeeze pin from being protruded toward to the molding space in the installation space; a rod bar which sticks to the lower end part of the squeeze pin; a cylinder body; a cylinder cap; and a rotation preventing tool.</p> |
