Abstract

A vermiculite core for a vehicle may include vermiculite and pearlstone, an aluminum component for the vehicle may be manufactured using the vermiculite core including the vermiculite and the pearlstone, and a method for manufacturing the vermiculite core for the vehicle may include mixing the vermiculite and the pearlstone, injecting a mixture of the vermiculite and the pearlstone into a mold, and pressing the mixture using a presser.

First claim

What is claimed is:

1. A vermiculite core for forging for a vehicle, the vermiculite core comprising vermiculite and pearlstone,
wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle,
wherein the vermiculite core includes a plurality of specimens horizontally in a forging direction.

2. The vermiculite core for forging for the vehicle of claim 1 , wherein a density of the vermiculite ranges from 0.1 to 0.25 g/cm 3 .

3. The vermiculite core for forging for the vehicle of claim 1 , wherein a density of the pearlstone ranges from 0.06 to 0.18 g/cm 3 .

4. The vermiculite core for forging for the vehicle of claim 1 , wherein the vermiculite core for forging for the vehicle is formed by pressing a mixture of the vermiculite and the pearlstone.

5. The vermiculite core for forging for the vehicle of claim 4 , wherein a density of the pressed mixture ranges from 0.4 to 0.8 g/cm 3 .

6. The vermiculite core for forging for the vehicle of claim 1 , wherein the vermiculite core for forging for the vehicle has a plurality of holes horizontally in a forging direction to form an aluminum column.

7. The vermiculite core for forging for the vehicle of claim 1 , wherein the vermiculite core for forging for the vehicle has a plurality of steel pins horizontally in a forging direction.

8. An aluminum component for a vehicle manufactured using a vermiculite core for the vehicle, the vermiculite core comprising vermiculite and pearlstone, wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle, wherein the vermiculite core for forging for the vehicle has a plurality of steel pins horizontally in a forging direction.

9. A method for manufacturing a vermiculite core for a vehicle, the method comprising:
mixing vermiculite and pearlstone;
injecting a mixture of the vermiculite and the pearlstone into a mold, wherein the mixture is injected to insert a plurality of steel pins horizontally in a forging direction; and
pressing the mixture using a presser;
wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle,
wherein the vermiculite core for forging for the vehicle has a plurality of steel pins horizontally in a forging direction.

10. The vermiculite core for forging for the vehicle of claim 1 , comprising a gap where an aluminum bridge is formed and is located in between two specimens and a longitudinal direction of the gap is horizontal to the forging direction.

11. A vermiculite core for forging for a vehicle, the vermiculite core comprising vermiculite and pearlstone,
wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle,
wherein the vermiculite core for the vehicle has a plurality of holes horizontally in a forging direction where a plurality of aluminum bridges are formed.

12. The vermiculite core for forging for the vehicle of claim 11 ,
wherein the vermiculite core for the vehicle has a plurality of holes horizontally drilled in a forging direction where an aluminum bridge is formed.

13. A vermiculite core for forging for a vehicle, the vermiculite core comprising vermiculite and pearlstone,
wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle,
wherein the vermiculite core for forging for the vehicle has a plurality of steel pins horizontally in a forging direction.
