Abstract
The present invention relates to a mixing, extruding, injecting and molding machine which is controlled by one CPU control system and comprises one motor for simultaneously driving and extruding a screw bolt and an oil pump, one extruder, one or a plurality of mold locking devices, and one or a plurality of plunger type injection devices.
Description
Technical field
The invention belongs to what macromolecular material processing and forming machinery apparatus field, a Coinjection molding apparatus is extruded in the compounding that relates to the mixing system of a kind of energy-efficient macromolecular material or multiple material.
Background technology
Extrude an injection moulding and be based on traditional injection molding technique, closing the compounding expressing technique is the novel processing technology in a step.Use this technology and can make the product that to make with traditional injection moulding, or be difficult to the product of manufacturing.In addition,, saved the intermediate link in many conventional machining process, reduced production cost because material is extruded, injection moulding one goes on foot and forms.
German patent DE 1142229 discloses a kind of plastics compounding injection (mo(u)lding) machine, this machine is furnished with a twin screw compounding device and a plunger type injection device, plastics are imported into injection device after the plasticizing of compounding device, be injected in the dies cavity by plunger advancement then.In plunger advancement injection and pressure maintaining period, the compounding device must quit work, compounding continuously.
U.S. Pat 2003075821, German patent DE 1052244 disclose a kind of in plunger advancement injection and pressure maintaining period, and the compounding device stops the compounding injection (mo(u)lding) machine of continuous operation between can be not.Its compounding device can be single screw rod or in the same way or antidromous double screw extruder, in plunger advancement injection and goods pressure maintaining period, the melting charge that is successively produced by extruder enters in the hold-up tank between an extruder and the plunger type injection device, that be connected by the materials flow pipe, when injection and pressurize end and plunger retreat, melting charge in the hold-up tank begins to be pressed in the plunger type injection device, is injected in the dies cavity by plunger again.But this what complexity of installing, the melt pressure fluctuation is bigger, so that the quality stability of final injection molded article is relatively poor.
European patent EP 1280648, U.S. Pat 2003038406 disclose a kind of mechanical device that can be used for addressing the above problem.The plasticizing extruder of this device and melting charge hold-up tank concentric in-line are arranged, in process of production, plasticizing extruder continuously operates, consequent melting charge enters the hold-up tank of plasticizing extruder front end through a unlimited switch valve, when reaching predefined injection volume, this switch valve cuts out, whole plasticizing extruder is moved forward by hydraulic oil cylinder driving, relies on the conducting element of plasticizing extruder inner screw front end that the melting charge in the hold-up tank is injected in the mould cavity through the switch valve that opens wide on nozzle.There are two big defectives in this mode that addresses the above problem and device: 1) action that is injected into mould cavity of the melting charge in this device will lean on the fast preceding in-migration of whole plasticizing extruder to finish, and its energy consumption is big, and control accuracy is low; 2) switch valve that is arranged on the plasticizing extruder screw front end in this device must cut out with pressure maintaining period in the melting charge injection, and plasticizing extruder is meanwhile constantly operating and constantly producing new melting charge, and can produce unexpected melt pressure and increase this moment.So loop cycle can produce bad injection molded article.
World patent WO03041940 discloses a kind of compounding injection (mo(u)lding) machine, can be used for the goods of the series of compounds of injection moulding tool different performance material.This patent has been described its hold-up tank and has been arranged on the barrel of the first end of plasticizing extruder inner screw melt zone, when the plunger advancement of the melt that the extruder continuous operation produces in the injection device that arrange the extruder bottom injected, enters hold-up tank.Melt when moving behind plunger in the hold-up tank and is continued melt extruded to screw front end with other material in extruder barrel, enter injection device again.Yet melt zone and other material that all will be pushed screw rod/barrel by the material in the what hold-up tank in each injection moulding cycle are once more met, motion forward again, therefore produce uprushing and whole barrel internal pressure distribution sudden change of melt zone material, produce the unsettled melt extrusion of quality during meeting.During but product molding that molding cycle short big at injection volume, also phenomenon under feeding may appear.
Yet above-mentioned patent does not all relate to the drive system of described device.
On October 25th, 2000 was to November 1, held in per 3 years at Dusseldorf ,Germany (D ü sseldorf) in the 15th the international plastic, rubber fair of world scale maximum once and put on display a kind of compounding injection (mo(u)lding) machine (exhibition booth 15-C/24), be used for producing (being tending towards endless) long fiber reinforced plastics goods, this machine compounding device stops continuous operation between can be not.Its compounding device is homodromal double screw extruder, in plunger advancement injection and goods pressure maintaining period, the melting charge that is successively produced by extruder enters in the hold-up tank between an extruder and the plunger type injection device, that be connected by the materials flow pipe, when injection and pressurize end and plunger retreat, melting charge in the hold-up tank begins to be pressed in the plunger type injection device, is injected in the dies cavity by plunger again.But this device melt pressure fluctuation is bigger, and melt need pass in and out the melt hold-up tank in the process, so that the quality stability of final injection molded article is relatively poor.
The extrusion screw rod of this machine and injection device are by two motor-driven, and one of them motor-driven screw rod rotates, and another motor-driven oil pump drives motions such as injection cylinder.Its control panel has two, a panel control injection device, and another controls extrusion device.
