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 a vehicle, the vermiculite core comprising vermiculite and pearlstone.

2 . The vermiculite core 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 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 the vehicle of claim 1 , wherein a content of the vermiculite ranges from 40 to 60% with respect to an entire volume of the vermiculite core for the vehicle.

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

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

7 . The vermiculite core for the vehicle of claim 1 , wherein the vermiculite core for the vehicle is formed divided into a plurality of specimens horizontally in a forging direction.

8 . The vermiculite core for the vehicle of claim 1 , wherein the vermiculite core for the vehicle has a plurality of holes horizontally in a forging direction.

9 . The vermiculite core for the vehicle of claim 1 , wherein the vermiculite core for the vehicle is formed to insert a plurality of steel pins horizontally in a forging direction.

10 . An aluminum component for a vehicle manufactured using a vermiculite core for the vehicle, the vermiculite core comprising vermiculite and pearlstone.

11 . 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 pearl stone into a mold; and pressing the mixture using a presser.

12 . The method for manufacturing the vermiculite core for the vehicle of claim 11 , wherein in the injecting, the mixture is divided and injected to form an aluminum bridge horizontally in a forging direction.

13 . The method for manufacturing of a vermiculite core for the vehicle of claim 11 , further comprising:
perforating the pressed mixture to have a plurality of holes horizontally in a forging direction, after the pressing.

14 . The method for manufacturing the vermiculite core for the vehicle of claim 11 , wherein in the injecting, the mixture is injected to insert a plurality of steel pins horizontally in a forging direction.
