Abstract

An apparatus includes a first mold having an injection cavity at a side thereof, for molding of a substrate, a second mold having two injection cores and two skin shaping plugs, and a third mold having a foaming section where a foaming material is injected between a substrate and a skin, and a skin shaping section where embossing is carried out on a skin, wherein, under the condition that the first mold, second mold and third mold are simultaneously closed to one another, a substrate is molded by the injection cavity and a first injection core, embossing is carried out on a skin by one skin shaping plug and the skin shaping section, and, at a same time, the foaming material is injected between a previously molded substrate and a previously embossed skin by a second injection core and foaming section.

First claim

What is claimed is:

1 . An apparatus for manufacturing a crash pad, comprising:
a first mold formed with an injection cavity therein, for molding of a substrate; a second mold provided, at a lower portion thereof, with a pair of injection cores while having, at an upper portion thereof, with a pair of skin shaping plugs, the second mold being rotatable about a longitudinal axis thereof by a rotating structure; and a third mold having, at a lower portion thereof, a foaming section in which a foam is formed between a substrate and a skin through injection of a foaming material while having, at an upper portion thereof, a skin shaping section in which embossing is carried out on a surface of a skin, the third mold performing an operation of feeding the skin embossed by the skin shaping section, wherein, under a condition that the first mold, the second mold and the third mold are simultaneously closed to one another, a substrate is molded by the injection cavity of the first mold and a first injection core of the second mold, embossing is carried out on a skin by one skin shaping plug of the second mold and the skin shaping section of the third mold, and the foaming material is injected between the molded substrate and the embossed skin by a second injection core of the second mold and the foaming section of the third mold, thereby manufacturing a crash pad.

2 . The apparatus according to claim 1 , wherein a foaming material mixing head is mounted to the third mold, to inject the foaming material.
