Abstract
An apparatus for manufacturing a crash pad having a foam layer by injecting and foam-molding a foam liquid between a base and a skin may include a first mold and a second mold which mold the base by injecting molten resin into a base forming space formed in a mold-closed state and a vacuum mold for vacuum-molding the skin, in which when the vacuum mold to which the formed skin may be attached may be mold-closed with the first mold, a foam space may be formed between the skin and the base of the first mold, and an injection channel for injecting the molten resin into the base forming space and a foam liquid injection channel for injecting the foam liquid into the foam space may be provided in the first mold, such that the first mold may be used as a foam mold, together with the vacuum mold.
Claims5
A method for manufacturing a crash pad having a foam layer by injecting and foam-molding a foam liquid between a base and a skin, the method including:
- injecting molten resin into a base forming space formed in a mold-closed state between a first mold and a second mold through an injection channel formed in the first mold, thereby forming the base having a through-hole for passing the foam liquid therethrough and at the same time, vacuum-molding the skin in a vacuum mold;
- separating the second mold from the first mold and then mold-closing the vacuum mold to which the vacuum-molded skin is attached with the first mold in which the base is formed;
- and
- injecting the foam liquid into a foam space between the base of the first mold and the skin of the vacuum mold through a foam liquid injection channel formed in the first mold, thereby foam-molding the foam layer,
- wherein the through-hole is formed to pass through the base by a pin portion installed in a cavity inner side of the second mold in the forming of the base.
