Abstract

A press apparatus for vehicle crash pads including real wood sheets. The press apparatus includes a lower press including an engraved part, and a support part to support an upper press, the support part having a fixing protrusion, the upper press including an embossed part, first slides fixed to maintain a shape of the engraved part during a compression process of the real wood sheet, the first slides compressing a rear surface of the real wood sheet while rising along the embossed part, and a second slide to compress the real wood sheet during the compression process of the real wood sheet. During a wrapping process of the real wood sheet, the second slide compresses the real wood sheet to an inner rear surface of a core while falling such that a portion of the real wood sheet bent inward of the engraved part is wound around the core.

First claim

What is claimed is:

1. A press apparatus for vehicle crash pads comprising real wood sheets, the press apparatus comprising:
a lower press comprising an engraved part disposed in an area in which a product is to be formed;
an upper press comprising an embossed part corresponding to the engraved part of the lower press;
a support part disposed on the lower press and configured to support the upper press when compressed towards the lower press;
a fixing protrusion extending from the support part and configured to fix a real wood sheet; and
one or more first slides disposed along a boundary of the engraved part of the lower press during a compression of the real wood sheet, the one or more first slides configured to:
travel longitudinally along the embossed part of the upper press and move laterally after travelling longitudinally towards the upper press; and
compress a rear surface of the real wood sheet after the upper press moves away from the lower press; and

one or more second slides disposed in the upper press and configured to:
compress the real wood sheet located on the engraved part together with the embossed part of the upper press; and
bend an end of the real wood sheet inwards towards an inner rear surface of a core while moving down from the upper press towards the lower press,

wherein the rear surface of the real wood includes a surface of the real wood distal from the embossed part, and
wherein the support part further comprises a fixing pin for fixing the real wood sheet.

2. The press apparatus according to claim 1 , wherein the one or more first slides are further configured to selectively move to maintain the shape of the engraved part of the lower press during the compression of the real wood sheet.

3. The press apparatus according to claim 2 ,
wherein the one or more first slides are further configured to compress the rear surface of the real wood sheet to the core while rising along the embossed part of the upper press, and then to move laterally; and
wherein the one or more second slides are further configured to compress the real wood sheet located on the engraved part together with the embossed part of the upper press during the compression of the real wood sheet.

4. The press apparatus according to claim 3 ,
wherein the one or more first slides are further configured to compress the rear surface of the real wood sheet after the second slide rises together with the upper press; and
wherein the one or more second slides are further configured to bend the end of the real wood sheet inward to be wound around the core.

5. The press apparatus according to claim 1 , further comprising:
one or more third slides fixed to maintain the shape of the engraved part of the lower press during the compression of the real wood sheet,
wherein the one or more third slides are configured to:
compress the rear surface of the real wood sheet while rising along the embossed part of the upper press; and
move laterally to cut off a portion of the real wood sheet.

6. The press apparatus according to claim 1 , wherein the real wood sheet comprises:
a real wood sheet body formed to have a shape of a real wood product;
one or more compression fixing ribs formed on the outside of the real wood sheet body to fix the real wood sheet;
wood sheet compression fixing ribs having a first fixing hole for fixing the real wood sheet to a press; and
a wrapping fixing rib formed on the outside of the real wood sheet body to fix the real wood sheet, the wrapping fixing rib having a second fixing hole formed by a hole processing pin of a preforming press to fix the real wood sheet to the fixing pin of the press apparatus.

7. A press apparatus for vehicle crash pads comprising real wood sheets, the press apparatus comprising:
a lower press comprising an engraved part disposed in an area in which a product is to be formed;
an upper press comprising an embossed part corresponding to the engraved part of the lower press;
a support part disposed on the lower press, the support part configured to support the upper press when compressed towards the upper press;
a fixing protrusion extending from the support part and being configured to fix a real wood sheet;
one or more first slides fixed on the lower press to maintain a shape of the engraved part of the lower press during compression of the real wood sheet, the one or more first slides configured to compress a rear surface of the real wood sheet while rising along the embossed part of the upper press and then to move laterally; and
one or more second slides disposed in the upper press, the one or more second slides configured to:
compress the real wood sheet located on the engraved part together with the embossed part of the upper press; and
move to a side of the embossed part to cut a portion of the real wood sheet deviating from a core,

wherein the support part further comprises a fixing pin for fixing the real wood sheet.
