Abstract

An apparatus for manufacturing an interior part of a vehicle may include a pressure sensor disposed at a position on a surface of a base of the interior part at which a foaming pressure of a foam material is detected, a tube controlling an expanding pressure, disposed on a surface of a skin layer of the interior part to press against the base, and a tube pressure controller for controlling the expanding pressure of the tube, which causes the skin layer to be pressed to the surface of the base, relative to the foaming pressure of the foam material detected by the pressure sensor during foaming of the foam material, to block leakage of the foam material.

First claim

What is claimed is:

1. An apparatus for manufacturing an interior part of a vehicle, comprising:
a pressure sensor disposed at a position on a surface of a base of the interior part at which a foaming pressure of a foam material is detected;
a tube exerting an expanding pressure, wherein the tube is disposed on a surface of a skin layer of the interior part to press against the base with the expanding pressure; and
a tube pressure controller for controlling the expanding pressure of the tube, wherein the expanding pressure of the tube is controlled to be higher than the foaming pressure of the foam material and causes the skin layer to be pressed to the surface of the base relative to the foaming pressure of the foam material detected by the pressure sensor during foaming of the foam material, to block leakage of the foam material.

2. The apparatus of claim 1 , wherein the base of the interior part includes a plurality of sealing protrusions formed at a position of the surface thereof at which the skin layer is closely pressed against the base, so as to block leakage of the foam material.

3. The apparatus of claim 2 , wherein the plurality of sealing protrusions of the base define therebetween trenches for confining the foam material therein.

4. The apparatus of claim 2 , further comprising a double-sided adhesive tape adhering to a surface area of the skin layer that contacts the plurality of sealing protrusions of the base.

5. A method of manufacturing an interior part of a vehicle, comprising:
disposing a tube controlling an expanding pressure to a position on a surface of a skin layer of an interior part at which a base of the interior part is pressed;
detecting a foaming pressure of a foam material disposed between the base and the skin layer of an interior part crash pad during foaming of the foam material; and
controlling the expanding pressure of the tube, to be higher than the foaming pressure of the foam material and to cause the skin layer to be pressed to the base, to such a degree as to discharge air and to block leakage of the foam material during foaming of the foam material, based on the detected foaming pressure.

6. The method of claim 5 , wherein, in the controlling the expanding pressure of the tube, the expanding pressure of the tube, which causes the skin layer to be pressed against the base, is controlled to such a degree as to provide a clearance between the skin layer and the base so as to allow air in a foaming space defined between the base and the skin layer to be discharged to an outside.

7. The method of claim 6 , wherein the controlling the expanding pressure of the tube to such a degree as to provide a clearance between the skin layer and the base is performed until the foam material reaches the clearance between the skin layer and the base due to foaming of the foam material.

8. The method of claim 5 , wherein the controlling the expanding pressure of the tube, which causes the skin layer to be pressed against the base, to such a degree as to block leakage of the foam material is performed from when the foam material reaches the clearance between the skin layer and the base due to foaming of the foam material.

9. The method of claim 5 , wherein the controlling the expanding pressure of the tube to such a degree as to block leakage of the foam material is performed to cause the skin layer to adhere to the base.
