The mold clamping is an area where the processor (mold setter) has significant influence over the cost of the molding parts.

Foul-up mold clamping setting causes jerking in the die mold (open & close) function and produce severe damage to the die tool parts.

Mold clamps are widely used in any injection molding machines, CNC machines and milling machines for holding the die part (mold) between the fixed and movable platen.

1.   The mold clamp is used for injection molding machine.

Mold clamp for an injection molding machine

A mold clamp for an injection molding machine with a stationary mold clamping plate and a movable mold clamping plate displaceable on a sliding carriage, which mold clamping plates are arranged on a machine frame and support mold-halves of a mold for processing plastic material, on the sliding carriage side guide rollers are provided which are adjustable with eccentric bolts and are supported on the machine frame, an air clearance is provided between the movable mold clamping plate and the sliding carriage, which are connected with each other for relative movement therebetween by connecting elements and a vertical trunnion transversely displaceable to the machine longitudinal axis, and are secured together with fastening screws.

Mold clamps are an important part of any molding operation. Insufficiently secured molds are susceptible to being damaged and this could cost a lot to repair.

2.   The mold clamp is used for CNC machine.

These Strap Clamps have teeth at rear matching to that of Step Blocks for the Step Blocks to be used as supports.

3.   The mold clamp is used for milling machine.

4.   The mold clamp is used for machine workpieces for supporting & holding.

The mold clamp fixture is specially designed according to the requirements of the machining process. The positioning component on the fixture enables the workpiece to quickly occupy the correct position relative to the machine and the tool. The positioning accuracy of the workpiece can be ensured without correction, and the productivity of the fixture is high. The positioning accuracy is high, but special fixtures need to be designed and manufactured, which are widely used in batch and mass production.

These Stepped strap Clamps have teeth at rear matching to that of Step Blocks for the Step Blocks to be used as supports. Unlike other clamps, a single piece of Step Block not a pair can be used as support with Stepped Strap Clamp.

The mold clamps are including so many styles, the most common using are the quick-change mold clamps, forged closed-toe mold clamps, stepped strap clamps, step blocks, universal mold clamps, U clamps, easy clamps, etc.

The mold clamps sizes differ as per the T-slots and thread dimensions available in the clamping platen of an injection molding machine, CNC machine, milling machine, etc.

CLAMPING PRECAUTIONS

1. Always use the correct size and quantity of mold clamps for your application. Follow your mold supplier's recommendations.

2. Always use the correct quantity of mold clamps to hold your mold in place. If in doubt, use more.

3. Never use an undersized bolt or washer with a mold clamp and always match the bolt and washer to the clamp slot and platen thread size and depth.

4. Inspect mold clamps, bolts, washers and platen threads regularly!

Do not use cracked or bent mold clamps.

5. Check and retighten all mold clamp bolts on a regular schedule.

6. Use closed-toe mold clamps where possible. They are stronger than open-toe clamps.

7. Always position the bolt as close to the mold as possible for maximum leverage and holding strength.

8. Always position the mold clamp so it is parallel to the platen. Use an adjustment bolt or shim to achieve parallel.

9. Bolt threads must penetrate your platen female thread a minimum of one and one half the thread diameter or more. A one inch bolt must

penetrate at least one and one-half inches. We suggest two times the diameter or more.

10. Be sure female platen threads are in good condition. If questionable use a thread repair insert to refurbish.
