Abstract
Abstract Individual mold assemblies are releasably secured to a table by latching means in the form of pivotally mounted finger elements which can swing into and out of engagement with a base structure associated with each mold assembly. A separate dumping means functions to engage and lift each mold assembly from the table, so that a part can be dumped therefrom, and the dumping means operates to automatically release the pivotally mounted finger elements from their engagement with a mold assembly when the dumping means is moved to a position for engaging and lifting the mold assembly.

Claim 3
Dependent Claim
52 words
The apparatus of claim 1 wherein each mold assembly includes a base structure which can be fitted into one of said openings in the supporting means, and wherein said latching means comprise pivotally mounted finger elements which can swing into and out of engagement with said base structure of a mold assembly.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein said base structure includes a recessed formation in a surface thereof for receiving portions of said finger elements, said recessed formation being of a sufficient size and shape to permit limited axial movement of a secured mold assembly relative to the supporting means.
Claim 5
Dependent Claim
48 words
The apparatus of claim 1, and including a dumping means for engaging, lifting, and removing an individual mold assembly from the supporting means after the mold assembly has been released from said latching means, so that a formed part can be removed or dumped from the mold assembly.
Claim 6
Dependent Claim
46 words
The apparatus of claim 4 wherein said dumping means includes a pair of spaced apart jaw elements mounted on a common axis so that said jaw elements can be moved toward and away from each other along said axis to engage and disengage a mold assembly.
Claim 7
Dependent Claim
59 words
The apparatus of claim 5 and including (a) a spring means for normally urging said pair of jaw elements toward each other to effect a gripping engagement of the jaw elements with a mold assembly and (b) hydraulic means for urging said pair of jaw elements away from each other to release a mold assembly from said gripping engagement.
Claim 8
Dependent Claim
36 words
The apparatus of claim 4 wherein said dumping means includes means for automatically releasing said latching means out of engagement with a mold assembly when the dumping means is moved into engagement with the mold assembly.
Claim 9
Dependent Claim
44 words
The apparatus of claim 4 and including rotating means for swinging said dumping means about said axis so that a mold assembly having a part therein can be moved from an upright position to an upside down position to thereby dump a part therefrom.
Claim 10
Dependent Claim
55 words
The apparatus of claim 8 and including a holding means for retaining a part within said mold assembly while the mold assembly is being moved to an upside down position, and further including means for releasing said holding means so that a part can fall from the mold assembly at a selected time or position.
Claim 11
Dependent Claim
35 words
The apparatus of claim 9 wherein said holding means is carried by said dumping means so as to automatically contact a mold assembly when the dumping means is brought into engagement with the mold assembly.
