What is the function of clamping unit?

Injection molding machine is divided into 2 units i.e. a clamping unit and an injection unit. The functions of the clamping unit are opening and closing a die, and the ejection of products.

What is clamping system in injection Moulding machine?

Injection molding is a manufacturing process for producing products by injecting melted plastic materials into a mold then cooling it to solidify it. Clamping force is necessary to hold the mold together against the pressure of the melted materials being injected to keep resin from spilling out.

What is the use of good clamping?

Meaning of Clamping Device: Clamping Device purpose is to hold work in the correct relative position in the fixture and to ensure that the job is not displaced under cutting forces. It is also necessary for clamping the jig to the work.

What is hydraulic clamping?

The hydraulic clamping is the pipe gripping done through by clamps which execute the opening movement and closing hydraulic pressure mode, unlike standard machines where all these movements are manually done. This is one of the most popular features of large diameter welding machines such as TracStar, mMegaMc.

What is clamping system also explain toggle clamping?

Toggle Type Clamping: To toggle is mechanical device to amplify force. In a moulding machine, which consist of two bars joined, together and to end with a pivot. When the mould is opened, the toggle is in the shape of a V. when the pressure is applied to the pivot, the two bars for a straight line.

What is the difference between toggle clamping system and hydraulic clamping system?

Toggle machines open with near full close tonnage ratings. Hydraulic machines are limited due to the ram design as the pressure is exerted against the shaft seals and wiper. For that reason, the opening pressure is limited. Now with newer clamp designs, the hydraulics is faster and more efficient than ever.

What is clamping and its types?

Screw clamps are types which use a screw mechanism to adjust the jaws and clamp a workpiece in place. The types which are found in the screw clamp category include G clamps (also known as C clamps), F clamps, edging clamps, wooden hand screw clamps and rack clamps.

What are clamping devices?

Clamping device are used to minimize the distortion during the machining process. Once the workpiece is located, it is necessary to hold it against the machining force. The mechanism used for this is known clamps. They are work holding devices usually positioned above the supporting surfaces.

What is hydraulic clamping unit?

How does a swing cylinder work?

These cylinders are Pull-Type cylinders where the piston rotates by 90° (CW or CCW) during the swing stroke and then travels in a straight line during the clamping stroke. A solid one-piece construction ensures perfect alignment of internal components and maximum clamping rigidity.

How does a pneumatic clamp work?

DESTACO Pneumatic Clamps use air-actuated cylinders to operate the clamping action. They are ideal for quick clamping in repetitive production operations, and yet are portable and economical to use on short run jobs with temporary fixturing.
