Abstract

PURPOSE:To provide a casting device which simplifies the driving mechanism of charging machines and a synchronizing mechanism for molds and the charging machines by synchronizing the charging machines with the molds which are conveyed by conveyors, and charging molten metal into the molds from the charging machines while the molds are held conveyed synchronously. CONSTITUTION:The 1st and 2nd charging machines 4, 5 are moved in the same direction as that of molds 1..., and are transferred synchronously with the molds 1... in accordance with the action of stoppers 26 for pallets 2, 2. In said state, the molten metals are charged from the respective ladles 20 of the machines 4, 5 into the molds 1.... Upon completion of the charging, the traveling of the machines 4, 5 is stopped, and the machines are transferred in the direction opposite from that of the molds 1..., so that stoppers 31 are displaced to non-operating positons. At the point of the time when the time enough for the two molds 1, 1 to outrun the the machines 4, 5 elapsed , the transfer direction of the machines 4, 5 is reversed and is transferred in the same direction as that of the molds 1.... Thereafter the above-discribed stages are repeated successively, whereby the molten metals are charged successively and repeatedly into the continuously moving molds 1....

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a casting apparatus configured to move a pouring machine in synchronization with a mold conveyed by a conveyor, and to pour metal from the pouring machine into the mold in the synchronously transferred state. Regarding.

In the above-mentioned conventional device, in order to synchronously transfer the pouring machine to the mold, the pouring machine is attached to a chain conveyor, and the chain conveyor is driven by an electric motor that can be driven in forward and reverse directions and has variable speed. is configured to be driven and reciprocated along the direction of transport of the wall-rud, and
A mechanism for detecting the relative position of the mold and the pouring machine is used to change the speed of the motor to move the pouring machine at the same speed as the mold.

However, in order to achieve synchronization, it is not only necessary to provide a mechanism to detect the relative position between the pouring machine and the mold, but also to quickly speed up the motor by Kf in conjunction with the position detection, which makes it difficult to use a rounding configuration for synchronization. It was complicated.
