Abstract
A molten metal feed apparatus of a die casting machine preventing shortening of the lifetime of a sleeve due to local heating of the sleeve, provided with a ladle having a receptacle for holding the molten metal and a conveyor system for conveying the ladle to a predetermined feed position of the sleeve of the die casting machine and tilting the ladle to pour the scooped up molten metal into the sleeve, wherein the position of a front end of a pouring spout of the ladle with respect to the sleeve is changed in accordance with a change in posture of the ladle while pouring the molten metal into the sleeve.
Claims9
A molten metal feed apparatus of a die casting machine comprising:
- a ladle having a receptacle for holding a molten metal and a pouring spout for pouring the molten metal;
- a conveying means for conveying said ladle to a predetermined feed position of a sleeve of the die casting machine, tilting the ladle, and pouring the scooped up molten metal into said sleeve;
- and
- a position changing means for changing a position of a front end of a pouring spout of said ladle with respect to said sleeve in accordance with a change in posture of said ladle while pouring the molten metal into said sleeve.
A molten metal feed method of a die casting machine comprising a steps of:
- scooping up molten metal by a ladle held by a conveyor system;
- conveying said ladle to a predetermined feed position of a sleeve of the die casting machine;
- pouring the scooped up molten metal into said sleeve by tilting said ladle;
- and
- changing a position of a front end of a pouring spout of said ladle with respect to said sleeve in accordance with a change in posture of said ladle while tilting said ladle to pour the molten metal into said sleeve.
A molten metal feed method of a die casting machine comprising a steps of:
- scooping up molten metal by a ladle held by a conveyor system;
- conveying said ladle to a predetermined feed position of a sleeve or the die casting machine;
- pouring the scooped up molten metal into said sleeve by tilting said ladle;
- and
- moving said sleeve in a predetermined range while pouring molten metal into said sleeve.
A ladle used for feeding molten metal to a sleeve of a die casting machine, comprising:
- a receptacle for holding the molten metal;
- a mounting hole to which a rotary shaft is to be attached;
- and
- a pouring spout for pouring molten metal held in said receptacle by rotation about said mounting hole, having a front end being apart from an axial line of said mounting hole.
