Modular clamp station

1. A modular mold clamp assembly for use in a molding machine, the assembly comprising:

a frame having a base member, a first end member and a second end member, the first and second end members having mounting areas provided thereon;

first and second platens movably mounted on the base member, the platens configured to mount mold halves thereon;

the platens being movable between an open and a closed position without transmitting forces to the frame;

whereby the frame, containing the platens, can be mounted or unmounted to the molding machine by the use of mounting hardware cooperating with the mounting area of the frame.

2. The modular mold clamp assembly as recited in claim 1 , wherein mounting openings are provided on the first end member and the second end member.

3. The modular mold clamp assembly as recited in claim 2 , wherein mounting hardware extends through the mounting openings to mount the modular mold clamp assembly to plates of the molding machine.

4. The modular mold clamp assembly as recited in claim 1 , wherein a drive is mounted on the base member, the drive cooperating with the first and second platens to move the platens between the open position and the closed position.

5. The modular mold clamp assembly as recited in claim 4 , wherein a cam follower is slidably mounted on the first end member, the cam follower coupled to the drive, whereby the movement of the cam follower moves the drive.

6. The modular mold clamp assembly as recited in claim 1 , wherein a pair of mounting rods extend through openings in mounting brackets, the mounting brackets being mounted to the base member of the frame.

7. The modular mold clamp assembly as recited in claim 4 , wherein the mounting rods are secured to a pin which extends through the first end member.

8. A rotary molding machine comprising;

a pair of turntables rotatably mounted on a shaft;

a plurality of modular mold clamp assemblies mounted on and spaced around the turntable, each modular mold clamp assembly including a frame having a base member, first and second platens movably mounted to the base member to permit movement of the platens toward and away from each other, and a mold clamp drive for opening and closing the platens;

the platens and mold clamp drive being mounted on the frame and being movable relative to the frame without transmitting forces to the frame;

whereby the frame can be mounted or unmounted to the turntables of the molding machine by the use of mounting hardware cooperating with the mounting area of the frame, the frame providing structural support to the pair of turntables.

9. The rotary molding machine as recited in claim 8 , wherein a first end member and an opposed second end member are integrally attached to the base member.

10. The rotary molding machine as recited in claim 9 , wherein at least one mounting rod extends from the base member, the first and second platens movably mounted on the mounting rod to permit movement of the platens toward and away from each other.

11. The modular mold clamp assembly as recited in claim 9 , wherein mounting openings are provided on the first end member and the second end member.

12. The modular mold clamp assembly as recited in claim 11 , wherein mounting hardware extends through the first mounting openings to mount the modular mold clamp assemblies to the turntables.

13. The modular mold clamp assembly as recited in claim 8 , an array of mounting openings is provided on the turntables, the mounting openings configured to accommodate multiple mold clamp assembly configurations.

14. The modular mold clamp assembly as recited in claim 8 , wherein a cam follower is slidably mounted on the first end member, the cam follower coupled to the mold clamp drive, whereby the movement of the cam follower moves the mold clamp drive.

15. The modular mold clamp assembly as recited in claim 8 , wherein a pair of mounting rods extend through openings in mounting brackets, the mounting brackets being mounted to the base member of the frame.

16. The modular mold clamp assembly as recited in claim 15 , wherein the mounting rods are secured to a pin which extends through the first end member.

17. A modular mold clamp assembly for use in a molding machine, the assembly comprising:

a frame having a base member, a first end member and a second end member, the first and second end members having mounting areas provided thereon;

first and second platens movably mounted on the base member, the platens configured to mount mold halves thereon;

the platens being movable between an open and a closed position;

a drive mounted on the base member, the drive cooperating with the first and second platens to move the platens between the open position and the closed position, whereby forces associated with moving the platens between the first and second positions are transmitted through the drive without transmitting the forces to the frame;

whereby the frame, containing the platens, can be mounted or unmounted to the molding machine by the use of mounting hardware cooperating with the mounting area of the frame.

18. The modular mold clamp assembly as recited in claim 17 , wherein mounting opening are provided on the first end member and the second end member.

19. The modular mold clamp assembly as recited in claim 18 , wherein mounting hardware extends through the mounting openings to mount the modular mold clamp assembly to plates of the molding machine.

20. The modular mold clamp assembly as recited in claim 17 , wherein a cam follower is slidably mounted on the first end member, the cam follower coupled to the drive, whereby the movement of the cam follower moves the drive.
