Working principle of fully automatic extrusion hollow plastic blowing machine equipment

Understanding the principle of automatic extrusion hollow blowing machine is to better operate the hollow blowing machine equipment and produce more reliable plastic hollow blowing products. Automatic extrusion hollow blowing machine is one of the commonly used equipment in the production of plastic hollow products, can also be called hollow molding machine, blowing machine, plastic forming machinery, can produce plastic products with different process requirements. So, what is the basic working principle of automatic extrusion hollow blowing molding machine equipment? Plastic raw materials in the screw extruder melting and quantitative extrusion, the formation of plastic raw materials, type embryo hot into the open mold inside, type embryo quantitative extrusion, mold, mold, closed mold immediately in the embryo into the compressed air, using the machine blowing the wind, blowing gas into the mold, the type embryo blow attached to a certain shape of the mold cavity, type embryo expansion close mold wall forming, again after the air ring blow cooling release, clamp will take out the products, complete the processing of plastic hollow products production. The production principle of hollow blowing machine is "squeeze-blow" blowing molding. The equipped extruder generally adopts frequency conversion motor, which can meet the process requirements of different plastic hollow products. Meanwhile, the extruded plastic type billet is relatively stable and uniform, thus ensuring the stability of product weight. The extrusion equipment of the hollow blow molding machine forms the billet through the extrusion machine head, and the billet enters the mold blowing molding, that is, to complete a production cycle.
