The present invention is an improved single cavity molding device and method for compression molding polyurethane, polyurea or polyurethane / polyurea hybrid covers over golf ball sub-assemblies. The device utilizes top and bottom mold-halves and is particularly novel in that it does not require the use of bolts to secure the mold-halves. The molding device utilizes a pair mold halves, each having a backing plate and mold frame for housing a hemispherical cavity mold. The invention utilizes a plurality of clamping pins, each pin having its top portion reciprocally disposed in a recess of the backing plate of the top mold. Double spring Belleville washers are coupled to the top portion of each clamping pin and upon the application of a vertical force, the washers are compressed to place the device in a controlled state of tension and also cause the clamping pins, to move downward into a locking position with slidable retainers to therein maintain a compressive force of at least 384 pounds on the golf ball sub-assembly for the molding process. Upon completion of the molding process, a vertical force is applied to the top of the clamping pins wherein they are moved out of a coupled relationship with the engagement loops, and with a coordinating horizontal biasing, the retainers are moved away from the pins, whereby the mold-halves may be then opened and a covered golf ball removed.
