Injection mold for timepiece component

An injection mold, comprising:

• a mold core comprising a first part and a second part, wherein the first part and the second part are mobile relative to one another between a first injection position in which the two parts are moved together to form an injection cavity permitting the injection of a material to form an injected part comprising at least one component, and a second demolding position in which the two parts are moved away from one another to permit the demolding of the injected part,
• at least one ejector designed to contribute to the demolding of the injected part, and
• at least one intermediate plate, which is separate from the two parts of the mold core, and movable,
• wherein the at least one intermediate plate is arranged between the two parts of the mold core, and has at least one first cutout forming at least one part of the injection cavity of the injection mold,
• wherein, in the injection cavity, a respective surface of each of (i) the mold core, (ii) the at least one first cutout of the intermediate plate, and (iii) the at least one ejector contributes to defining a shape of the injected part.
