Abstract
The utility model relates to the technical field of injection molding, in particular to a novel high-efficiency energy-saving injection molding machine. The novel high-efficiency energy-saving injection molding machine comprises an injection device, a threaded rod and a driving motor. A reduction gearbox is connected between the threaded rod and the driving motor. The use of an oil pump motor is completely abandoned, the reduction gearbox is directly connected between the threaded rod and the driving motor, and the speed of the driving motor is steplessly regulated through a programmable logic controller (PLC) control converter, so that the energy consumption is reduced, the same effects can be achieved by a low-power driving motor, and meanwhile, the use of cooling water is reduced to reduce electric energy loss for the circulation of the cooling water. Compared with the prior art, the novel high-efficiency energy-saving injection molding machine has the advantages of simple structure, low manufacture cost, high efficiency and energy saving, and has broad market prospect.
Description
Technical field
The present invention relates to the injection molding technology field, particularly a kind of novel high-efficiency and energy-saving injection machine.
Background technology
Injection moulding is the thermophysical property that utilizes plastics, plastics are added the feeding cylinder from hopper, barrel is outer to make the plastics melting with the gas ket heating, outer power motor is housed in that barrel is in-built, under the effect of motor, drive the screw rod of rotation, material is under the effect of screw rod, be fed forward and compacting along screw channel, material is gradually plasticizing under the double action of external heat and screw rod shearing, melting and homogenizing are when screw rod rotates, material is under the effect of screw channel frictional force and shearing force, shift the material of melting the head of screw rod onto, meanwhile, screw rod retreats under the reaction of material, make screw head form the storing space, finish plasticizing process.Then screw rod is under the effect of injection cylinder piston thrust, be expelled to the melting charge in the storage compartment in the die cavity of mould by nozzle with high speed, high pressure, melt in the die cavity by pressurize, cold cut, curing molding after, mould closes opening mold under the effect of structure at matched moulds, and fall from mould ejection by the liftout attachment goods that solidifying and setting is good, finish all injection process.
In the injection machine in the prior art, it is when preformed, screw rod in Plasticized component is by the rotation of fluid motor-driven main shaft, main shaft one end is connected with the screw rod key, the other end is connected with the hydraulic motor key, during the screw rod rotation, material plasticizing, screw rod will plastify good melt and shift onto in the storage compartment of barrel front end, meanwhile, screw rod retreats under the reaction of material, and by thrust bearing thrust bearing is retreated, and directly retreat by nut pulling piston rod, finish metering, during injection, the cylinder chamber oil-feed of injection cylinder is by the execution of bearing pushing piston bar, and bar chamber oil-feed pushing piston bar and the screw rod of piston are finished action of injection, and it realizes that by the motor-driven oil pump motor conversion of electric energy-mechanical energy-hydraulic energy finishes injection process, there are some problems in the injection machine of this structure, such as by the motor-driven oil pump motor time, need powerful motor to guarantee the normal operation of motor, therefore power consumption is larger, and complex structure, manufacturing cost is high.
Summary of the invention
For existing defective and problem in the injection machine in the solution prior art, provide a kind of novel high-efficiency and energy-saving injection machine.
The present invention is that the technical scheme that its technical problem of solution adopts is: novel high-efficiency and energy-saving injection machine of the present invention comprises injection device, screw rod and a drive motors, between described screw rod and drive motors, be connected a reduction box, described drive motors main shaft is connected with reduction box input shaft, reduction gearbox output shaft is connected with screw rod, and drive motors adopts stepless speed-regulating motor.
Outside described reduction box, also be equipped with for the automatic brake that solves screw rod injection moulding revolution problem.
The invention has the beneficial effects as follows: compared with prior art, novel high-efficiency and energy-saving injection machine of the present invention has been abandoned the use of oil pump motor fully, and between screw rod and drive motors, directly be connected a reduction box, and control frequency converter by PLC drive motors is carried out stepless speed regulation, thereby reduce energy consumption, can use low power drive motors to reach the same effect, reduced simultaneously the use of cooling water, reduced the electric energy loss of cooling water circulation, have simple in structure, low cost of manufacture and energy-efficient advantage have good market prospects.
Description of drawings
Below in conjunction with the drawings and specific embodiments novel high-efficiency and energy-saving injection machine of the present invention is described further.
Fig. 1 is the part-structure schematic perspective view of novel high-efficiency and energy-saving injection machine of the present invention.
The specific embodiment
As shown in Figure 1, novel high-efficiency and energy-saving injection machine of the present invention comprises an injection device 1, screw rod 2 and drive motors 3, between screw rod 2 and drive motors 3, be connected a reduction box 4, drive motors 3 main shafts are connected with reduction box 4 power shafts, reduction box 4 output shafts are connected with screw rod 2, and drive motors adopts stepless speed-regulating motor.The automatic brake 5 of revolution problem when outside reduction box 4, also being equipped with for 2 injection moulding of solution screw rod.
As shown in Figure 1; when work; original PLC controls exterior frequency converter by injection machine; carry out stepless speed regulation and open arbitrarily, shut down by Frequency Converter Control drive motors 3; transmit torsion to reduction box 4 by drive motors 3, reach the function that increase torsion underspeeds, by reduction box 4 torsion is delivered to screw rod 2 again; screw rod 2 is rotated, thereby carry out injection work.
As shown in Figure 1, adopt the injection machine of this structure, abandoned the use of general oil pump motor in the prior art fully, can greatly reduce the use of electric energy, take the 1600T injection machine as example, the general motor of 4 37kW that adopts of the injection machine of this type of the prior art drives oil pump motor, make the total specified power of motor reach 148kW, and adopt the injection machine of structure of the present invention, then a motor that the total specified power of needs is 55kW gets final product, simultaneously, oil pump motor of the prior art needs cooling, therefore need a cooling recirculation system, also can consume many electric energy, its machine energy-saving of injection machine by the structure of the present invention that obtains after improving can reach more than 40%, electric energy loss in injection moulding process then can reduce about 60%, simultaneously, its structure is also simpler than of the prior art, and manufacturing cost and maintenance cost are also lower, therefore, it has simple in structure, and low cost of manufacture and energy-efficient advantage have good market prospects.
, but should be understood that in the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
