Mold clamp
First Claim
1. A mold clamp comprising:
- a base constructed and arranged to be mounted on a first mold half, a drive including a cylinder body and a piston with said piston pivotally mounted to said base about a pivot point, a first abutment constructed and arranged to be mounted to said cylinder body, a second abutment constructed and arranged to be mounted on a second mold half, and a cam arranged between said first abutment and said piston for rotating said cylinder body about said pivot point of said piston upon actuation of said drive to move said first abutment between a retracted position engaging said second abutment to apply a closing force between said first and second mold halves and an extended position with said first abutment canted away from said second abutment to allow reciprocating relative motion between said first and second mold halves.

Abstract
A mold clamp has a drive pivotally mounted on a first mold half. The drive includes a cylinder body and a piston, wherein one of the cylinder body or the piston is pivotally mounted to the first mold half and the other has a pair of pins and a locking plate having an engagement face. A guide directs the drive between a retracted position and an extended position. The guide has a pair of spaced apart guide plates mounted to the first mold half. Each guide plate has an arcuate slot slidably receiving the pins. An abutment is mounted on a second mold half. The abutment has a complementary engagement face for cooperating with the engagement face of the drive for enhancing engagement therebetween. When the drive is in the retracted position, the drive engages the abutment to apply a closing force between the first mold half and second mold half; when the drive is in the extended position, the drive is canted away from the first mold half allowing reciprocating relative motion between the first mold half and said second mold half.
