Document Type and Number:
WIPO Patent Application WO/2020/250456
Kind Code:
A1
Abstract:
Provided is a parting lock device for an injection mold in which a base holder (2) and a lock member (8) can be disconnected even in a state where a lock bar (13) is inserted into the lock member (8), and which ensures stable movement of the lock bar (13), structural simplification, facilitation of production and assembly, and miniaturization. A first engagement element (6) and a first spring (7) are incorporated into the base holder (2). In a position in which a lock plate (10) is inserted into a plate insertion hole (4), the first engagement element (6) is moved to a lock position to connect the base holder (2) and the lock member (8). When the lock bar (13) is removed from a bar insertion hole (3), the first engagement element (6) is pushed into an unlock position in which the base holder (2) and the lock member (8) are disconnected.
