Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of macromolecule plastic membrane pressurization vacuum injection formation system and the method for forming that can the bubble in the molten plastic be discharged and form relative vacuum.
Design: in order to realize above-mentioned purpose of design; The application is on the basis of background technology: the barrel of extruding in the pressue device is equipped with the vacuum suction mouth and adopts vacuum air pump to the design that the high molecule plastic of extruding in the tube vacuumizes, and is major technique characteristic of the present invention.The purpose of doing like this is: because the application is equipped with spiral agitator below the piston head in the screw extrusion machinery in pressue device; This agitator is in the process of on one side the fusion high molecule plastic being pushed downwards; Stir on one side, bubble in the molten plastic is discharged and, make the high molecule plastic of fusion be in relative vacuum state by the vacuum air pump sucking-off; When the macromolecule molten plastic of vacuum state is pressed into the diaphragm forming chamber; Not only the density of the macromolecule plastic membrane of institute's moulding is real, and can not produce air pocket, has guaranteed the Forming Quality and the service life of macromolecule barrier film.
Technical scheme 1: a kind of macromolecule plastic membrane pressurization vacuum injection formation system; The outlet of high molecule plastic plasticizing machine is communicated with the import of pressue device; The outlet material of pressue device is communicated with the import of macromolecule plastic membrane injection mold; The barrel of extruding in the said pressue device is equipped with the vacuum suction mouth, and the outlet of vacuum suction mouth is communicated with the magnetic valve import, and electromagnetic valve outlet is communicated with the vacuum suction machine air entry; Spiral agitator is housed below the piston head in the screw extrusion machinery in the said pressue device.
Technical scheme 2: a kind of macromolecule plastic membrane pressurization vacuum injection method of forming; The high molecule plastic raw material is after plasticizing; Be heated into molten condition; Before the plasticizing plastics of molten condition get into pressue device and by the piston in the screw extrusion machinery in the pressue device macromolecule plasticizing plastics pressurization of molten condition are injected into the forming cavity of macromolecule plastic membrane mould; The agitator puddling on one side molten plastic, one that is arranged in the piston below connects to be discharged the bubble of molten plastic and the bubble of plastics is taken away through vacuum suction mouth and vacuum air pump; Make molten plastic be in vacuum state, be pressed into pressurization typing in the macromolecule plastic membrane mould molding chamber then, can die sinking take out diaphragm after the cooling.
The present invention compares with background technology; The one, the application adopts pressurization to vacuumize; Fundamentally solved the generation of air pocket in the plastic diaphragms; Guaranteed the Forming Quality of plastic diaphragms and greatly prolonged service life of plastic diaphragms, greatly reduced user's use cost, solved that people want to solve for a long time and the difficult problem that not have solution.
