A mold, or die is easily and conveniently maintainable, includes releasably retained parts and permits access and removal of mold parts or elements that may need maintenance, repair or replacement without removal of the mold or die from a die casting machine.
Claims18
A die for casting a V-block for an internal combustion engine in a die-casting machine having a stationary platen and a movable platen, comprising:
- a stationary die element for mounting on the stationary platen of the die casting machine, and
- a movable die element for mounting on the movable platen of the die-casting machine, said movable die element carrying a plurality of transversely movable, cavity-forming slides and at least a pair of cylinder-forming die parts removably retained in means for reciprocating the pair of cylinder-forming die parts at an acute angle with respect to the movement of the movable platen between extended positions within the die cavity and retracted positions within the movable die element, each of said at least a pair of cylinder-forming die parts having a rearward portion providing an engagable surface, locking elements carried within, and accessible from outside of, said reciprocating means, engaging the engagable rearward portions of the cylinder-forming die parts for removably retaining said cylinder-forming die parts in said reciprocating means, and die core locking means for locking the cylinder-forming die parts in their extended positions.
A die for casting a V-block for an internal combustion engine in a die-casting machine having a stationary platen and a movable platen, comprising:
- a stationary die element for mounting on the stationary platen of the die casting machine, and
- a movable die element for mounting on the movable platen of the die-casting machine, said movable die element carrying a plurality of transversely movable, cavity-forming slides and at least a pair of cylinder-forming die parts, and means for reciprocating the at least a pair of cylinder-forming die parts at an acute angle with respect to the movement of the movable platen between extended positions within the die cavity and retracted positions within the movable die element, said cylinder-forming die parts being removably held in said movable die element by rearward engagable portions within the means for reciprocating the at least a pair of cylinder-forming die parts and holding elements movably carried by the reciprocating means between holding positions in which they engage the rearward engagable portions of the cylinder-forming die parts and releasing positions in which they are disengaged from the rearward engagable portions of the cylinder-forming die parts.
