Mold including a locking device

Abstract

The invention relates to a mould (1) for moulding, in particular by injection, that comprises two half-moulds (2, 3) each defined by a side surface (21, 31), a front face and a rear face. One at least of said two half-moulds is to be associated with means for opening and closing the mould. The two half-moulds can be brought into contact at the level of a junction plane (1) when the mould is in the closed position. The mould is characterised in that one half-mould is provided with a locking device (6) that comprises: at least one latch (7) that can be simultaneously housed in a recess (25) in each half-mould (2, 3); and at least one independent system (8) capable of bringing together or separating the latch (7) and the recesses (25, 35) in which the latch (7) is to be received, and including one or more jack(s) (8) including a chamber connected to the half-mould, a piston capable of movement in said chamber, and a rod connected to the piston and to which the latch is attached.
