Abstract
The present invention relates to a die casting machine which includes a dispenser that causes a plunger lubricant to undergo a phase change. The dispenser also dispenses the plunger lubricant. The present invention also relates to a method of lubricating a die casting machine which involves effecting a phase change in the plunger lubricant prior to dispensing the plunger lubricant. The present invention also relates to a plunger lubricant blank which under goes a phase change in the dispenser.
Claims21
A die casting machine, comprising:
- a shot sleeve adapted to receive a plunger lubricant;
- and
- a dispenser adapted to cause the plunger lubricant in a first phase state to undergo, at least partially, a phase change to a second phase state and adapted to dispense the plunger lubricant into the shot sleeve.
A die casting machine, comprising:
- a dispenser adapted to cause a plunger lubricant in a first phase state to undergo, at least partially, a phase change to a second phase state and adapted to dispense the plunger lubricant;
- and
- a shot sleeve adapted to receive the plunger lubricant from the dispenser.
A method of lubricating a die casting machine, comprising:
- storing a plunger lubricant in a first phase state;
- effecting a phase change in a plunger lubricant using a dispenser;
- and
- dispensing the plunger lubricant into the die casting machine.
A die casting machine, comprising:
- a dispenser adapted to cause a plunger lubricant in a first phase state to undergo, at least partially, a phase change to a second phase state and adapted to dispense the plunger lubricant into a shot sleeve, wherein the dispenser is adapted to dispense the plunger lubricant in two phase states.
A die casting machine, comprising:
- a dispenser adapted to cause a plunger lubricant in a first phase state to undergo, at least partially, a phase change to a second phase state and adapted to dispense the plunger lubricant into a shot sleeve, wherein the dispenser and the shot sleeve are adapted to prevent a second phase change in the plunger lubricant.
