Detailed description of the invention
See Fig. 1-3: a kind of sign board injection mold, comprises cover half, dynamic model, core rod, dynamic model comprises dynamic model cover plate above and is connected to the dynamic model base of both sides below cover plate, is provided with several upwards dynamic model guide pillars on dynamic model cover plate top; The die cavity run through up and down is provided with in the middle part of dynamic model; Several core rod pilot holes are provided with above dynamic model; Be provided with in the middle part of dynamic model and run through cold slug well up and down, cold slug well both sides are provided with groove and are communicated with die cavity; Cover half is provided with the matched moulds pilot hole of dynamic model guide pillar coupling, and what in the middle part of cover half, cold slug well was corresponding is provided with cast sprue, and sprue both sides are provided with the cast runner be communicated with die cavity; Core rod comprises core rod seat board and is positioned at several the core rod guide pillars mated with core rod pilot hole above core rod, is also provided with the core rod body mated with die cavity above core rod seat board, is provided with the cold burden push rod poured into a mould rising head with cylindricality and mate in the middle part of core rod seat board; The height of core rod body is more than or equal to die cavity height.
Dynamic model and dynamic model base are by bolted; Pin is provided with between dynamic model and dynamic model base; Cover half is provided with gate bush, and gate bush is provided with the sprue gate matched with sprue, runner; Dynamic model cover plate, core rod seat board, cover half are all coordinated by upper and lower two parts cover plate and form; All be provided with flange bottom core rod body, guide pillar, push rod, embed top cover plate from bottom to top, lower cover is connected by screw upper cover plate, is provided with pin between upper and lower cover plates.
Inside dynamic model base, correspondence is provided with the flange matched with core rod, makes core rod movable in dynamic model; Core rod and core rod guide pillar are fixed on dynamic model base; After injection moulding completes, dynamic model base, along guide pillar upwardly core rod body, makes workpiece move up with core rod and exceed die cavity upper surface, is more conducive to retract workpiece and saves production efficiency; Dynamic model base is also provided with cold burden push rod, and cold burden push rod coordinates with cold slug well, and while core rod upwardly, push rod plays cleaning effect to cold slug well; Be provided with flange bottom guide pillar, push rod, and embed upper cover plate from bottom to top, lower cover is connected by screw upper cover plate, better improves the stationarity of guide pillar.
