Mold Clamps

Mold clamp standard

There are two processing standards for mold clamps. National Standard Machinery Standard: GB∕T 699-1988. The second type of machinery department standard JB∕T 8044-1999.

Mold clamp includes quick-change mold clamp, U-shaped mold clamp, open-end mold clamp, closed-end mold clamp, universal mold clamp, easy clamp, forged clamp, machined mold clamp, injection molding clamp, mold base clamp, etc.

Mold clamp is a kind of auxiliary fixture often used in mold processing. Its main function is to make the workpiece not vibrate or shift during processing. To ensure the accuracy of the molded workpiece and a good finish.

Therefore, the quality of the mold pressing plate directly affects the product quality of the mold. Mold clamp plays a vital role in the mold manufacturing process. The mold clamp has high strength, small size, flexible and simple operation.

The manufacturing process of mold clamp

It is made of 45# medium carbon steel material with a forging press. After high-temperature heating and hammer hammering, the hardness can reach above 30HRC.

Then use a universal milling machine to process the plane and long grooves to achieve a surface finish of 3.2. As well as the parallelism and flatness of the platen, all errors are not more than 0.02MM.

After heat treatment and quenching, it reaches 35HRC to 40HRC required by JB. Finally, the surface is blackened or blued to achieve the purpose of preventing rust spots.

The Mold Support Clamp is used to hold a mold in position on a vertical steel column or angle.

Mold clamps are widely used in any injection molding machine for holding the die part (mold) between the fixed and movable platen. More durable than less expensive, case-hardened clamps.

These clamps can fasten Molds whether they are changed vertically or horizontally. Attach the clamps on the fixed-platen side to prevent the mold from rotating or the locating ring from disengaging from the alignment hole, but do not yet fully tighten the bolts to the specified torque value. Properly secure connection Wrong connection.

Adjust the injection pressure, clamp pressure, and the volume of material to be injected (if this feature is available). It all depends on the complexity of your mold and the parts it will make.

Find the correct tonnage of clamp force this mold requires and set it appropriately; do not assume that full clamp force is needed. Sizing And Inspection Before installing a mold, a machine must be selected that is properly sized for the specific mold being installed.

The injection nozzle on the machine must be aligned with the mold cavity. There is also a range of different Die Clamps available to suit your injection molding or mold casting requirements.

How to Mount an Injection Mold?

DGMF’s Mold Clamps are easy to install and reduce set up time.
Are you setting clamp tonnage based on the mold or the machine?
Remember that to proof your mold, the injection molders have to schedule machine time, dry or otherwise prepare your raw material, and install and set up your mold.

Setting Up A Mold – How to install and set up an injection mold properly. Swivel base adjusting screws come standard with most assemblies.

Often it will not inject all the way, leaving a shortened product or it will inject too much, and plastic can shoot out of the mold. Just because you are running in a 500-ton press doesn’t mean you should be clamping to 500 tons.

You can now use this clamping force to multiply by the total projected area to establish the recommended clamp force for your mold.

Start the machine, make sure the injection sled is in the full-back position, and set the barrel heaters to the proper temperatures.
The mold clamps are machined to fit into the T-slot of the bolster for extra secure positioning.

3/4 part of eyebolt screw enters into holes of mold, 2 eyebolts used to secure the transport and personal security.

The flange-mount die clamps can be bolted onto the bolster and the automatic slider model die clamps make the remote automatic operation possible.

You can take a dial indicator reading to see the rise or fall of a tool as it unclamps and clamps, If the moving platen side moves as much as the leader pin clearance when the mold faces kiss, rehang your tool.
The material is then injected into the mold under high pressure. Washers are extra-large and made of hardened steel.

Thread Tools.

Simply bolt the platen plates onto the machine’s platens, install manifolds, place clamps in slots, and connect hoses and you’re ready for production.
