Abstract
The invention discloses a parallel injection method. More than two feeding ejaculation units are connected in parallel through a check valve and ejaculate to a die through a nozzle. A special equipment injector comprises a locking mechanism and the feeding ejaculation units for the feeding ejaculation to the die. The feeding ejaculation unit comprises a charge pipe, a screw, a screw driving mechanism and a feeding mechanism. The feeding ejaculation unit is provided with a heating mechanism and an insulation mechanism. The nozzle of the feeding ejaculation units faces towards the die. The nozzle is connected with more than two feeding ejaculation units in parallel. The ejaculation port of every feeding ejaculation unit is communicated with the nozzle through the check valve.

Description
Technical field
The present invention relates to a kind of injection molding forming method and injection machine.
Background technology
Known injection machine cooperates single injection material pipe by single screw rod, makes large-scale plastic components if desired, then needs large-scale injection machine.For example, the pipe joint of the present large-scale plastic conduit 70-120 kilogram that weighs, the practitioner need purchase large size plastic jetting-moulding device and could satisfy and produce.Large size plastic jetting-moulding device equipment is huge, costs an arm and a leg, and the investment payback time is long.Its two, the molten amount of moulding of the single mode of large size plastic jetting-moulding device is big, molding cycle is very long, generally needs 10-30 minute, production efficiency is low.Its three, in order to ensure the size of product, the material pipe after shooting material, need pressurize, pressurize generally comes the feed liquid in the mould is keep-uped pressure by the plunger on drive screw or the material pipe, because the screw rod of large size plastic jetting-moulding device and material pipe are very big, the electric power that consumes in the pressure maintaining period is very big, has improved production cost.They are four years old, in order accurately to implement pressurize, need implement closed loop servo control to screw rod or plunger, by measurement, feedback to the pressure in the material pipe, the application of force of control screw rod or plunger, but because the material pipe size of large size plastic jetting-moulding device is big, the pressure of inner each point changes obviously, cause the measurement data of selected measurement point all to be difficult to reflect truly material pipe pressure inside situation, cause control accuracy and reduce, influence the stability of product size.At last, the shot capacity of the injection machine of single screw rod is determined, the product that can not workmanship be higher than its specified gram number, and consider economy, also be not suitable for the lower product of workmanship rank, its result is exactly that the practitioner need be the injection machine of other product purchase correspondence of each grade of its manufacturing.
Summary of the invention
The present invention will solve that existing large size plastic jetting-moulding device price is expensive, molding cycle is long, energy consumption is high, the holding pressure control precision is low, the shortcoming of bad adaptability, provides that a kind of cost is low, adaptability good, energy consumption is low, holding pressure control precision height, short injection moulding process and the equipment thereof of molding cycle.
Parallel type injection moulding method of the present invention, adopt reinforced injection unit to the mold injects moulding, described reinforced injection unit comprises material pipe, screw rod, it is characterized in that: reinforced injection unit more than two is penetrated mould through a nozzle after the check valve parallel connection.
Further, described each reinforced injection unit penetrates successively.
Further, penetrate repeatedly again after each reinforced injection unit penetrates successively.
Use the injection machine of parallel type injection moulding method of the present invention; comprise clamping, mould penetrated the reinforced injection unit of feed; described reinforced injection unit comprises material pipe, screw rod, screw drive mechanism, feeding mechanism; dispose heating arrangements and heat preservation mechanism on the described reinforced injection unit; the corresponding mould of the nozzle of described reinforced injection unit; it is characterized in that: be parallel with plural reinforced injection unit on the described nozzle, the exit wound of bullet of the material pipe of each described reinforced injection unit all is communicated with described nozzle by check valve.
Further, the exit wound of bullet of described each reinforced injection unit is connected on the interface of an interface model, is communicated with the pipeline of described interface and described nozzle in the described interface model in addition.
Further, the driving mechanism of the feeding mechanism of described reinforced injection unit and screw rod is controlled by a central controller of programming in advance.
During work, each reinforced injection unit is under the coordination of central controller, and respectively charging in order, ejaculation for example, are done when penetrating action when a unit, and charging, fusing action are done in another unit, and mould is done continuous injection, and preface is injected repeatedly successively.Because the material pipe of each unit is significantly smaller than single material pipe, therefore can reduce the power of machine, shorten molding cycle.Also can multiple-unit inject in the lump.
The present invention is converted to the order injection moulding of many reinforced injection units or injection moulding or merging injection moulding repeatedly with the shot of traditional injection moulding machine.Thus, can replace a large-scale reinforced ejecting mechanism by a plurality of small-sized reinforced ejecting mechanism in parallel, reduce equipment cost greatly.
The present invention can be according to the actual needs of product, increase and decrease the quantity of reinforced injection unit in parallel, increased the adaptability of equipment greatly, can reduce the amount of purchasing to the injection machine of different stage of factory, reduce production costs.
When pressurize, do pressurize separately as long as start the screw rod of a reinforced injection unit, other unit are closed.According to Pascal's theorem, at this moment, the pressurize effect at nozzle place is identical with the legacy equipment that uses single material pipe and screw rod.Because screw rod that the present invention drove is significantly smaller than legacy equipment, therefore, the present invention's spent electric energy when pressurize is less.
Because the size of material pipe reduces, the inhomogeneities of material pipe pressure inside reduces, the more approaching material pipe of the measurement data pressure inside situation of selected measurement point, and the SERVO CONTROL precision improves, and the stability of product size improves.
Advantage of the present invention is: cost is low, adaptability good, energy consumption is low, holding pressure control precision height, molding cycle short.
