The space-spanning pouring
system for the iron mold sand
coating process of the present invention comprises a pouring cup, a
sprue and a bridge pouring runner, the bridge pouring runner comprises a semi-
arch bridge channel, a runner and a riser, the bottom of the pouring cup is connected to the top of the
sprue, the two ends of the bottom of the
sprue are respectively connected to one end of the semi-
arch bridge channel, the two semi-
arch bridge channels constitute an arch bridge channel, the other ends of the two semi-arch bridge channels are respectively connected to one side of the runner, the two ends of the runner are respectively connected to the riser, and one or both sides of each riser are connected to the ingrown. Molten iron is introduced into the arch bridge channel through the pouring cup and the sprue, flows through the
slag bag, the filter screen, the runner and the riser in sequence, and is injected into the product
casting mold through the ingrown. The pouring
system can increase the spatial placement channel of the product
casting mold, so that the amount of product castings produced by a single box is increased by 1.5 to 2 times, with high production efficiency, high output rate, stable quality, convenient operation, and suitable for promotion.
