PURPOSE: A detachable molding pin is provided to enable convenient replacement of a molding pin because the thickness or diameter of the molding pin head is smaller than that of the molding pin body. CONSTITUTION: A detachable molding pin comprises a body and a head(521a). The body is inserted into the cavity of a molding device so that the outer circumference of the body corresponds to a through hole formed in a molding core forming the edge of the cavity. The head is extended from an end of the body and inserted in a receiving groove(531). The head has a stepped groove(521b) which is selectively restricted by a fixing element of a clamping unit of a molding pin clamping device. The thickness of the head is less than the thickness of the body so that the molding pin can be selectively separated toward the inside of the cavity through the through hole.
