It is a main forming equipment for making various shaped plastic products with thermoplastic plastics or thermosetting plastics by using plastic forming mould.
The forming process of a common screw injection molding machine comprises the following steps: granular or powdery plastic is firstly added into a machine barrel, the plastic is made into a molten state through the rotation of a screw and the heating of the outer wall of the machine barrel, then the machine carries out die assembly and the forward movement of an injection seat, a nozzle is made to be close to a sprue of a die, then pressure oil is introduced into an injection cylinder, the screw is made to advance, so that molten materials are injected into the closed die with lower temperature at higher pressure and higher speed, and after certain time and pressure maintenance (also called pressure maintaining) and cooling, the molten materials are solidified and molded, and then the die can be opened to take out products.
The wire drawing is a phenomenon that the front end of the main runner is not broken and stretches into a wire shape, and the biggest problem is that a formed product cannot fall off due to the wire drawing and is clamped by a mold, so that continuous forming cannot be performed. The better the drawability (the property of being able to elongate into filaments when stretched in a molten state) of the resin, the more severe the drawing will be, thus avoiding the occurrence of the phenomenon of drawing and effectively improving the production efficiency of the injection molding machine.
The common method for solving the wire drawing phenomenon is to reduce the temperature of a cylinder, reduce the temperature of a nozzle, reduce the temperature of a die, or accelerate the die opening speed and increase the die opening amount, so that the wire drawing can be reduced to a certain extent.
