To provide an injection molding device which press-fits a terminal into a body using a force applied for closing a metal mold, and which manufactures a resin-integrated case having a terminal, a section of the terminal being covered by resin.
The injection molding device 200 includes a first metal mold 210, a second metal mold 220, and a driving device 250. The first metal mold secures a body 120 having a terminal 140 positioned thereon. The second metal mold is supported at a place opposite to the body 120. The driving device brings two metal molds near. The second metal mold includes a slide member 230 and a spring 232. The slide member projects elastically from a place on the second metal mold surface, the place being opposite to the terminal positioned on the body. The spring biases the slide member such that it projects from the second metal molding surface. When the metal molds are brought near, the slide member abuts against the terminal positioned on the body and is press-fitted into a protrusion 124. When the metal molds are further brought near, the terminal is press-fitted into a base of the protrusion, and then the metal molds close while the slide member retreats.
