The invention relates to a household electric appliance accessory
casting device which comprises a rack. A
pressure casting barrel and a mould are arranged on the rack. The
pressure casting barrel communicates with a discharging
pipe. An outlet of the discharging
pipe faces an inlet of the mould. A
cutting port is reserved between the outlet of the discharging
pipe and the inlet of the mould. A
pressure casting block is connected into the pressure
casting barrel in a sliding mode. The pressure
casting block is fixedly connected with a push rod. A
piston cylinder is arranged on the rack. The push rod is connected into the
piston cylinder in a sliding mode. The side, away from the push rod, of the
piston cylinder communicates with an air inlet pipe. An
air pump is fixed to the rack. A valveis arranged on the air inlet pipe. A time-
delay mechanism used for increasing the opening degree of the valve in a time-
delay mode is further arranged on the rack. The rack is in sliding connection with a cutter used for
cutting pressure casting materials in the
cutting port. An ejection rod used for pushing the cutter is fixed to the push rod. Compared with the prior art, by arranging the pressure casting block, the time-
delay mechanism, the cutter and the like according to the scheme, the operating efficiency is improved, and operating steps are also simplified.
