An injection mold comprising an actuator assembly for actuating at least one valve pin, which comprises: a. a displaceable actuator plate for actuating at least one valve pin during operation in an axial direction (z); and b. a valve pin coupling device interconnecting the valve pin and the actuator plate in the axial direction (z) manually switchable between i. a coupled state in which the valve pin in the axial direction (z) is interconnected to the actuator plate and ii. a decoupled state in which the valve pin in the axial direction (z) is disconnected from the actuator plate; wherein c. the valve pin coupling device is interconnected to the actuator plate and comprises: i. a coupling device first part having a side wall extending in the axial direction (z) and comprising at least one passage extending across the side wall from a first side face to a second side face and in which a coupling means is arranged displaceable in the passage and which protrudes at least above one of the first side face or the second side face of the side wall; ii. a coupling device second part arranged adjacent to the first side face, comprising a coupling recess suitable to receive the coupling means protruding above the first side face; characterized in that iii. a coupling device switching element arranged adjacent to the second side face and comprising a decoupling recess being arranged displaceable with respect to the coupling device first part between 1. a coupled first position in which the coupling means arranged in the passage of the coupling device first part is pressed via the coupling device switching element into the coupling recess of the coupling device second part, thereby coupling the coupling device first part and the coupling device second part; and 2. a decoupled second position in which the coupling means arranged in the passage of the coupling device first part is partially arranged in the decoupling recess such that the coupling device first part and the coupling device second part are decoupled from each other. a. a displaceable actuator plate for actuating at least one valve pin during operation in an axial direction (z);
