Method of forming air vent holes of a rear case for an lcd monitor, and an apparatus therefor

A method of forming air vent holes in a case of a monitor, comprising the steps of:

• placing a first mold, which has a first surface in which pin holes are formed, and a second mold, which has a second surface in which protrusion pins are formed, relative to each other to be in an injection position, so that a gap is formed between the first and second surfaces and the projection pins become respectively inserted into the pin holes;
• injecting a solution into the gap, and forming the rear case from the solution, wherein the air vent holes are formed at positions where the projection pins are located within the gap;
• and
• separating the first and second molds from each other.

A mold for forming air vent holes in a case of a monitor comprising:

• a first mold having a first surface in which pin holes are formed;
• and
• a second mold, which has a second surface in which protrusion pins are formed, relatives to each other;
• wherein a gap in a shape of the case is formed between the first and second surfaces and the projection pins respectively insert into the pin holes so that the protrusion pins extend through the gap, when the first and second molds are placed in a predetermined position relative to each other.
