Mold, method of manufacturing article, and valve

A mold including a first cavity and a second cavity, the mold comprising:

• a hot runner that forms a flow path to inject a resin injected from an injection unit into the first cavity and the second cavity;
• and
• a switching valve configured to divide the flow path into a first path connected to the first cavity and a second path connected to the second cavity,
• wherein the injection unit is connected to the first path,
• wherein a pressurizing unit is connected to the second path,
• wherein the switching valve includes a valve body disposed inside the flow path,
• wherein the valve body includes a first surface, a second surface, and a third surface connecting the first surface and the second surface,
• wherein the third surface has a groove and projected portions,
• wherein the first surface has three or more protrusions,
• wherein the first surface and the second surface respectively face the second path and the first path, and
• wherein a pressure receiving area of the first surface that receives pressure from melted resin in the second path is larger than a pressure receiving area of the second surface that receives pressure from melted resin in the first path.
