Life of this patent

Estimating the term…

Abstract

An injection mold includes an actuator assembly, which further includes an actuator plate for moving at least one valve pin during production in an axial direction and a valve pin coupling device. The valve pin coupling device allows a manually controllable coupling and decoupling of the actuator plate and the valve pin.

Dependent claims

An injection mold (1) comprising an actuator assembly (2) for actuating at least one valve pin (3), which comprises:

a. a displaceable actuator plate (4) for actuating at least one valve pin (3) during operation in an axial direction (z);
and
b. a valve pin coupling device (5) interconnecting the at least one valve pin (3) and the actuator plate (4) in the axial direction (z) manually switchable between;
i. a coupled state in which the at least one valve pin (3) in the axial direction (z) is interconnected to the actuator plate (4);
and
ii. a decoupled state in which the at least one valve pin (3) in the axial direction (z) is disconnected from the actuator plate (4);
wherein
c. the valve pin coupling device (5) is interconnected to the actuator plate (4) and comprises:
i. a coupling device first part (6) having a side wall (7) extending in the axial direction (z) and comprising at least one passage (8) extending across the side wall (7) from a first side face (9) to a second side face (10) and in which a coupling means (11) is arranged displaceable in the at least one passage (8) and which protrudes at least above one of the first side face (9) or the second side face (10) of the side wall (7);
ii. a coupling device second part (12) arranged adjacent to the first side face (9), comprising a coupling recess (13) suitable to receive the coupling means (11) protruding above the first side face (9);
and
iii. a coupling device switching element (14) arranged adjacent to the second side face (10) and comprising a decoupling recess (15) being arranged displaceable with respect to the coupling device first part (6) between
1. a coupled first position in which the coupling means (11) arranged in the at least one passage (8) of the coupling device first part (6) is pressed via the coupling device switching element (14) into the coupling recess (13) of the coupling device second part (12), thereby coupling the coupling device first part (6) and the coupling device second part (12);
and
2. a decoupled second position in which the coupling means (11) arranged in the at least one passage (8) of the coupling device first part (6) is partially arranged in the decoupling recess (15) such that the coupling device first part (6) and the coupling device second part (12) are decoupled from each other.
