The device is characterized in that the sensor installed beside a cavity can monitor filling state of the sensor at any time and transmits the signals to the control unit; the control unit sends a control signal to control switching of each valve, so as to achieve intelligent control on the filling process; and each valve device is provided with an electromagnetic switch control device, which can accurately control switching of the valve.
Description
Affiliated technical field
The present invention relates to be used for the Coinjection molding apparatus of the Based Intelligent Control melt filling process of sequential injection moulding process.
Background technology
Large-scale injection member is produced in the moulding of utilization conventional injection such as fascia and bumper etc. tend to produce tangible weld mark, warpage and other blemish.Usually overcome above problem through the method that improves injection pressure, prolongs the dwell time or adjust article construction and mould structure, thereby increased production cost, prolonged the production cycle, and often do not reached perfect condition.
Summary of the invention
The object of the present invention is to provide when can effectively improve large-scale injection member quality, shorten molding cycle, the sequential injection shaped device of the Based Intelligent Control filling process that reduces production costs.
For achieving the above object, this device is made up of hopper, extruding feed mechanism, melt filling intelligent control unit and mould.Described extruding feed mechanism comprise screw rod that barrel, barrel inside can rotatablely move, with the inner power source that links to each other of screw rod, the heater coil on the barrel.Described barrel links to each other with manifold through nozzle, and manifold links to each other with the cover half piece of described mould through a plurality of valvings that can independent gauge tap, and cover half piece and dynamic model piece have the relative molded surface that can constitute die cavity.Described valving comprises valve, valve bushing and valve rod.Described manifold and valving are equipped with heater coil, guarantee that melt is in desired state in forming process.Described barrel is through the cover half piece assembling of nozzle, manifold, valving and described mould.Described melt is filled intelligent control unit; Comprise sensor, control module, a plurality of valvings that can independent gauge tap; And the signal input line road between sensor and the control module, and between control module and the valving many control signal circuit outlet lines independently.Hopper is installed in the top of barrel.
This device comprises barrel; Be installed in the hopper on barrel top, the heater coil on the described barrel, screw rod, manifold, a plurality of valving, sensor, control module, the mould that barrel inside can rotatablely move; It is characterized in that being installed in sensor on the die cavity limit and can monitor the occupied state of die cavity at any time; And signal passed to control module; Send the switch that control signal is controlled each valving by control module, realize the intellectuality control of filling process, described valving is equipped with the accurately switch of by-pass valve control of electromagnetic switch control device.
Good effect of the present invention is to realize the sequential injection process; Open the injection melt like some injection ports, a last injection port is closed when melt is just crossed next injection port, and next injection port is opened the injection melt; So realize the sequential injection forming process; Can be good at eliminating the weld mark and other forming defect of moulding, improve the surface quality and the internal soundness of product, make the processing dimension of product more reliable and more stable.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
