| titleOfInvention | A manufacturing method for uniformly forming a covering thickness of a heating bar for a hair iron |
| abstract | The present invention relates to a manufacturing method for uniformly molding the coating thickness of an improved hair heating rod for hair iron so that the thickness of the coating coated on the outer peripheral surface of the hair heating rod can be uniformly coated, and the hair heating rod for hair iron manufactured thereby. About. The present invention is a core 23 with a rod hole 21 provided in the molding mold 20 made of a pair of first and second mold frames 20a and 20b and a concave head hole 22 communicating with it in the longitudinal direction. ), a long metal rod 11 having a heater built-in hole 13 and a head 12, and a molding material such as rubber, viton, silicone, and plastic are inserted into the outer periphery of the metal rod 11 14) is insert-molded to cover the hair heating rod 10, in which the head portion 12 of the metal rod 11 itself is covered in a protrusion or net shape of the size of the thickness to be coated with the molding material. After securing the coating gap (L) of the desired thickness by attaching the gap maintaining means (31, 32), the molding material is added to the molding mold (20), and the coating layer (14) has a constant thickness on the outer surface of the metal rod (11). Gap maintaining means 30 in the form of a protrusion in the concave head hole 22 forming a molding space inside a pair of the first and second mold frames 20a and 20b of the molding mold 20 to be covered with insert molding. ), and make the center line in the longitudinal direction of the metal rod 11 coincide with the center line of the forming space so that the desired coating gap (L) is made, and then the molding material is coated on the outer surface of the metal rod 11 with a certain thickness. A concave head hole 22 formed inside a pair of first and second mold frames 20a and 20b to be insert-molded or a protrusion-shaped central protrusion 15 provided at the center of the tip of the head 12 ) The center line in the longitudinal direction of the metal rod 11 coincides with the center line of the forming space by being inserted into the central concave hole 24 formed in communication with the center so that the desired covering gap (L) is made, and then the molding material is It is made to be insert-molded to cover the outer surface of the metal rod 11 with a certain thickness. |
