Injection molding machine clamping force appropriate, can speak a little detail, thank you
The clamping force can be calculated, usually you buy the device, if it is not very high requirements of ordinary products would roughly calculate the clamping force, then give you the choice of models, in the production process of locking force as small as possible, the clamping force is smaller for the same exhaust, the clamping force is small mechanical wear is small, generally in the product requires locking force plus five percent can be, too no, but there is a problem can not be ignored, is the parallelism of the template, the template parallelism is good, the better to die protection, for example, he said our domestic equipment, the new machine if good process debugging, but the machine for a few years, with the clamping force of products is certainly not original, because of the great deformation of crankshaft machine is not what optimization in the template, if you in here Lock mode requirements higher, you can try some companies do box type template, the so-called box type template is a big box, hollowed out inside, the template than ordinary to thick, and the production of less deformation.
This machine is calculated according to the projected area of the product clamping force, the clamping force must be greater than the cavity pressure, otherwise it will lock mode, causing flash
The clamping force of the injection molding machine varies greatly with the injection molding end surface area. For example, the 100 ton injection molding machine has an end area of 80 square centimeters, and the pressure gauge in the mould indicates about 120. Clamping force is appropriate, (about 80, 90 tons or so) qualified products. If the end area of a product is 50 square centimeter, the pressure gauge in the mould indicates about 80, and the clamping force is about 50 or 60 tons. Can produce qualified products. The general situation is to explore their own experience, and grasp their own. There are no definite rules. Excessive clamping force. The injection molding machine is seriously worn and suffers great losses. Clamping force is too small, products appear (cloak or gel edge). For reference only.
