Claims (1)
形成すべく前記コアダイに配置された傾斜スライ
ドコア。 ｄ 前記傾斜スライドコアをスライド自在に貫通
し、前記第１のアンダーカツト部とは抜き方向の
異なる第２のアンダーカツト部を前記成形品の内
側面に形成するコアピン。 ｅ 前記コアピンの根元部を保持し、傾斜スライ
ドコアの前進と共にコアピンの先端を成形品から
離脱させる、コアダイ内の傾斜案内路。[Scope of claims for utility model registration] An injection mold with the following components. a Cavity die. b Core die. c. An inclined slide core placed in the core die to form a first undercut on the inner surface of the molded product. d. A core pin that slidably passes through the inclined slide core and forms a second undercut portion on the inner surface of the molded product, with a drawing direction different from that of the first undercut portion. e. An inclined guide path in the core die that holds the base of the core pin and causes the tip of the core pin to separate from the molded product as the inclined slide core moves forward.
