Kingplas - Chinese Plastic Blow Moulding Machine Manufacturer
The opening and closing mode of the plastic extrusion blow molding machine of the blow molding machine is an important process in the plasticization, injection, pressure keeping and cooling, product molding and product demoulding of the injection machine. With the opening and closing mode action of the mold clamping device, the mold can form a cavity of the injection molded product, thereby ensuring that the mold cavity is not expanded by the pressure of the injection melt, thereby ensuring the quality of the injection molded product. It can be seen that the firm reliability of the combination of the forming mold, the movement flexibility of the mold opening and the convenient and safe removal of the finished part are all ensured by the accurate and reliable action of the mold clamping device.
The movement of the common clamping device is completed by a hydraulic cylinder, and the cylinder is in the form of a liquid-filled supercharged type and a liquid-filled type. The characteristics of the hydraulic clamping device are: the whole process of the movement of the injection opening and closing mold (the front and back movement of the template) and the clamping force are all controlled by the pressure control of the hydraulic oil.
