Abstract
A piston molding machine comprising a base on which a pair of mold supports are mounted for movement in a straight line toward and away from one another. A mold half is mounted on each support, and when the mold halves are juxtaposed they provide a cavity for forming a piston. A mold cap is pivoted to each mold half about a transverse axis rearwardly of the face of the mold half. A piston motor extends between each cap and its respective mold support for pivoting the mold cap into position adjacent the mold half to define the top of the cavity and away from the mold half to provide clearance for removal of a piston formed in the mold.
Claims14
In a piston molding machine, the combination comprising
- a base,
- a pair of mold supports mounted on said base for movement in a straight line toward and away from one another,
- means for moving said mold supports toward and away from one another,
- a mold half mounted on each support,
- said mold halves when juxtaposed providing a cavity for forming a piston,
- a mold cap pivoted to each mold half about a transverse axis rearwardly of the face of the mold half,
- and means extending between each cap and its respective mold support for pivoting said mold cap into position adjacent the mold half to define the top of the cavity and away from the mold half to provide clearance for removal of a piston formed in the mold.

In a piston molding machine, the combination comprising a base, a pair of mold supports mounted on said base for movement in a straight line toward and away from one another, means for moving said mold supports toward and away from one another, a mold half mounted on each support, said mold halves when juxtaposed providing a cavity for forming a piston,
- a mold cap for each mold half,
- means for pivotally connecting each said mold cap to its respective mold half about a transverse axis rearwardly of the face of the mold half,
- and means adapted to extend between each cap and its respective mold support for pivoting said mold cap into position adjacent the mold half to define the top of the cavity and away from the mold half to provide clearance for removal of a piston formed in the mold.
In a piston molding machine, the combination comprising a base, a pair of mold supports mounted on said base for movement in a straight line toward and away from one another, means for moving said mold supports toward and away from one another, a mold half mounted on each support, said mold halves when juxtaposed providing a cavity for forming a piston, the method of converting said machine to cast pistons having a configuration on the end thereof comprising
- pivoting a mold cap to each mold half about a transverse axis rearwardly of the face of the mold half,
- and providing means extending between each cap and its respective mold support for pivoting said mold cap into position adjacent the mold half to define the top of the cavity and away from the mold half to provide clearance for removal of a piston formed in the mold.
