Definitions
- the present invention relates to a mold for molding a molded product. More specifically, the present invention relates to a metal mold for mold that can be easily opened and that can form a desired number of gates at desired positions.
- Structural molding is a molding method in which a molten metal is filled into a mold (die, sand mold, etc.) having a product shape gap (molding space), and the molten metal is cooled and solidified to obtain a product. Since it can be manufactured in one process, it is used in the manufacture of automotive parts such as cylinder blocks, cross members, wheels, etc. In recent years, fabrication using a fabrication die having a plurality of gates (hereinafter, also simply referred to as a mold) has been performed (Japanese Patent Laid-Open No. Hei 5-269569, etc.).
- Such a casting mold is characterized by the fact that the molten metal is poured into the mold from a plurality of gates, so that the distance that the molten metal flows through the mold is short, and the temperature of the molten metal does not decrease much. It has the advantages of good hot water flow, few production defects, and the ability to handle thin-walled products.
- a fabrication die having a plurality of gates has a drawback that the molten metal is often exposed to the outside air and the like, and that portion is easily oxidized. Therefore, a structure is often adopted in which a gate is opened on the outer periphery of the cavity and the cavity and the gate are connected by a weir.
- the oxide film is held at the gate portion that is cut and removed in a later step, so that the oxide film is formed on the product surface as in a structure in which the gate is directly opened to the cavity. Is difficult to remain.
- a plywood mold is used in a state in which individual molds are combined using a divided construction mold composed of a plurality of molds. With such a structure, it is possible to separate these molds and open the molds after the completion of the fabrication, so that the product can be easily taken out.
