Abstract

A wood preforming device that manufactures a crash pad for a vehicle including a real wood sheet is provided. The wood preforming device includes a lower press mold including a debossed portion disposed on a portion of the lower press mold on which a product is to be formed, and a support portion supporting an upper press mold when the lower press mold and the upper press mold are compressed. The support portion has a fixing protrusion fixing the real wood sheet, the upper press mold has an embossed portion corresponding to the debossed portion of the lower press mold. A movable core provided on the debossed portion of the lower press mold guiding the real wood sheet by moving upward from the debossed portion when the upper press mold moves downward, and a steam module spray steam with a preset capacity to an edge portion of the debossed portion.

First claim

What is claimed is:

1. A wood preforming device comprising:
an upper press mold comprising an embossed portion;
a lower press mold comprising:
a debossed portion disposed on a portion of the lower press mold on which a preformed real wood sheet is to be formed, the debossed portion corresponding to the embossed portion of the upper press mold; and
a support portion configured to support the upper press mold when the lower press mold and the upper press mold press each other, the support portion including one or more fixing pins to insert into and position a real wood sheet on the lower press mold;

a movable core disposed on the debossed portion of the lower press mold, the movable core configured to guide the real wood sheet by moving in an upward direction from the debossed portion when the upper press mold moves in a downward direction; and
a steam module configured to spray steam with a preset capacity to an edge portion of the debossed portion of the lower press mold when the upper press mold is moved in a downward direction to the lower press mold,
wherein the steam module is disposed in the lower mold.

2. The wood preforming device of claim 1 , wherein the steam module is further configured to operate when the embossed portion of the upper press mold and the debossed portion of the lower press mold press each other.

3. The wood preforming device of claim 1 , wherein the steam sprayed by the steam module comprises at least one of a moisture and an aqueous stain.

4. The wood preforming device of claim 1 , wherein the steam module is further configured to spray the steam to the real wood sheet mold for a preset heating time when the real wood sheet is seated on the lower press before the embossed portion of the upper press mold and the debossed portion of the lower press mold press each other.

5. The wood preforming device of claim 1 , wherein the lower press mold further comprises a hole machining pin to form a seating hole in the real wood sheet.

6. The wood preforming device of claim 5 , wherein during a press compression molding to form the preformed wood sheet between the upper press and the lower press, the hole machining pin is moved in an upward direction to form the seating hole in the real wood sheet.

7. The wood preforming device of claim 1 , wherein the preformed real wood sheet is detached by moving the upper press mold in the upward direction.

8. The wood preforming device of claim 3 , wherein the aqueous stain comprises an aqueous paint.

9. A wood preforming device comprising:
an upper press mold comprising an embossed portion;
a lower press mold comprising:
a debossed portion disposed on a portion of the lower press mold on which a preformed real wood sheet is to be formed, the debossed portion corresponding to the embossed portion of the upper press mold; and
a support portion configured to support the upper press mold when the lower press mold and the upper press mold press each other, the support portion including one or more fixing pins to insert into and position a real wood sheet on the lower press mold;

a movable core disposed on the debossed portion of the lower press mold, the movable core configured to guide the real wood sheet by moving in an upward direction from the debossed portion when the upper press mold moves in a downward direction; and
a steam module configured to spray steam with a preset capacity to an edge portion of the debossed portion of the lower press mold when the upper press mold is moved in a downward direction to the lower press mold,
wherein the support portion further includes one or more retractable pins.

10. The wood preforming device of claim 9 , wherein the steam module is further configured to operate when the embossed portion of the upper press mold and the debossed portion of the lower press mold press each other.

11. The wood preforming device of claim 9 , wherein the steam sprayed by the steam module comprises at least one of a moisture and an aqueous stain.

12. The wood preforming device of claim 9 , wherein the steam module is further configured to spray the steam to the real wood sheet mold for a preset heating time when the real wood sheet is seated on the lower press before the embossed portion of the upper press mold and the debossed portion of the lower press mold press each other.

13. The wood preforming device of claim 9 , wherein the lower press mold further comprises a hole machining pin to form a seating hole in the real wood sheet.

14. The wood preforming device of claim 13 , wherein during a press compression molding to form the preformed wood sheet between the upper press and the lower press, the hole machining pin is moved in an upward direction to form the seating hole in the real wood sheet.

15. The wood preforming device of claim 9 , wherein the preformed real wood sheet is detached by moving the upper press mold in the upward direction.

16. The wood preforming device of claim 11 , wherein the aqueous stain comprises an aqueous paint.
