Zusammenfassung:	To provide a mold that can shorten the molding cycle time and prevent cost increase.SOLUTION: A mold has a first cavity and a second cavity, with a hot runner, which is a flow path for injecting resin injected from an injection device into the first cavity and the second cavity, and a switching valve installed in the middle of the hot runner to divide the flow path into a first flow path connected to the first cavity and a second flow path connected to the second cavity. The first flow path is connected to the injection device, and the second flow path is connected to a plunger.SELECTED DRAWING: Figure 1 【課題】成形サイクルタイムの短縮およびコストアップの防止を図ることができる金型を提供する。【解決手段】第一のキャビティおよび第二のキャビティを有する金型であって、射出装置から射出された樹脂を前記第一のキャビティおよび前記第二のキャビティに射出するための流路であるホットランナーと、前記ホットランナーの途中に設けられ、前記流路を前記第一のキャビティと接続される第一の流路と前記第二のキャビティと接続される第二の流路とに分断する切換バルブと、を有し、前記第一の流路には、前記射出装置が接続され、前記第二の流路には、プランジャが接続されていることを特徴とする。【選択図】図１
