ABSTRACT:
A mold assembly (34) for cyclically forming heated glass sheets includes a lower mold (36) having an upwardly oriented mold face (356) and an upper mold face having a downwardly oriented mold face (56) that opposes the upwardly oriented mold face of the lower mold to form a heated glass sheet during movement of the molds toward each other. Alignment guides (122,124) align the molds (36,38) with each other as necessary during movement of the molds toward each other. Detachable connectors (362) detachably connect the molds to each other for installation and are disconnectable to permit the molds to be used for glass sheet forming. In one embodiment, the detachable connectors (362) are latches that include a latch member (364) and a keeper (366), and in another embodiment the detachable connectors are retainers (370) engageable and disengageable from the molds to provide their detachable securement. The upper mold (38) includes a support plate (372) having mounting portions (374,376) and mounting guide portions (378,380,382) for providing alignment during mounting.
