Abstract

PURPOSE:To continuously cast small sized casting product at high speed by closely bringing a tapered part into contact with round tapered receiving part arranged at lower part of pouring basin part in a holding furnace, arranging a runner in the tapered part and intermittently discharging molten metal from the pouring basin part by rotating the tapered part. CONSTITUTION:The round tapered receiving part 5 is arranged at lower part of the pouring basin part 4 in the holding furnace 1 and closely brought into contact with the tapered part 9 provided in a runner opening/closing rod 7. Then, the runner opening/closing rod 7 is inserted into a protecting partition wall 2 to protect it from the molten metal 16, and in the tapered part 9, an outlet side runner 10 intermittently communicating with an inlet side runner 6 in the pouring basin part 4 by the rotation thereof, is arranged. By this constitution, at the time of driving a rotating device 11, the runner opening/closing rod 7 is rotated in accordance with rotation of a shaft 8, and the outlet side runner 10 in the tapered part 9 and the inlet side runner 6 in the pouring basin part 4 are intermittently communicated and at every time of communicating, the molten metal 16 is discharged. By this method, the simple product of small sized casting can be continuously cast at high speed and by executing mass- production, the production cost can be reduced.

(b) Conventional technology Traditionally, mass production of small cast products has been in the field of sand casting. This is due to the fact that no equipment has been developed for mass producing small cast products by continuous casting. Small amounts of melting especially for single casting of small castings? It is fatal that there is no complete quantitative pouring device that can continuously pour hot water into No. 4 uniform quantities. The present invention is a quantitative pouring device by lot rod operation devised by the present applicant (patent application filed in 1986-2).
No. 34197), it has a more precise structure and a mechanism that reduces heat loss of the materials used.

(d) Means for Solving the Problems The present invention isolates and protects a stopper made of refractory from the molten metal with a partition wall, and directs the molten metal from the sump of the holding furnace through a thin nozzle into the taper at one end of the stopper. We have adopted a method in which the hot water is tapped directly into the mold via a tap nozzle installed in the mold.
The problem of material wear and tear was solved because the area of the materials used that was exposed to the molten metal was made extremely small.

(F) Function To explain the function of the embodiment of the present invention with reference to Figs. 1 to 3, when molten metal 1G is put into the sump (4) of the holding furnace (1) and the turner α is operated, , its rotating shaft α2 rotates, and this rotation is a repeated rotation within the same angle. For example, after a 90° clockwise rotation, the stopper (7) is rotated clockwise or counterclockwise by repeating a 90° counterclockwise rotation and returning to the original position. In Fig. 1, the tap nozzle hole 10 of the stopper (7) is the main nozzle hole (
6), but 9 of the stopper (7)
As shown in Fig. 3, by 0° rotation, the tap nozzle hole C1O
has changed its position so that it is not connected to the main nozzle hole (6) of the main body. In other words, in Figure 1, the molten metal α0
indicates that the melt is being tapped from the main nozzle hole (6) into the lower mold (It) via the tap nozzle hole α0,
In Figure 3, from the main nozzle hole (6) to the tap nozzle hole C
This shows a state in which the pipe leading to the IO has been lost and hot water has been stopped. Intermittent hot water supply is achieved by repeating this hot water supply and hot water supply stop state. By adjusting the left and right rotation time of the rotating shaft (I2) of the turner (11) to a constant value.

Figures 5 and 6 show the stopper (7) and the partition wall (2) being taken out of the holding furnace (1) and the sump (4) of the holding furnace (1).
) through the main nozzle hole (6) opening at the bottom of the molten metal (I
It has the same effect as the one shown in FIGS. 1 to 3 in that it guides the hot water d to the tapered part (5) and intermittently adjusts the amount of hot water coming from the tap nozzle hole (10) by repeatedly rotating the stopper (7).
