Injection machine working method of the present invention, have employed above-mentioned glue injecting device, injection machine can be realized entirely control and half control two kinds of patterns: full control pattern be when lock control part 14 enter cylindrical shell lock nut 9 on nut seat 10 time (nut 9 and nut seat 10 form one and move integrally), injection mechanism utilizes the energy storage of elastic energy storage assembly, speed, the pressure of collaborative injection motor 7 whole-process control injection process; Half control pattern is when lock control part 14 exits cylindrical shell and removes the locking to nut 9 (between the cylindrical shell of nut 9 and nut seat 10 can relative sliding), injection mechanism utilizes the energy storage of elastic energy storage assembly to carry out the injection action of injection first half section, and injection motor 7 carries out the pressure and speed control of injection speed descending branch and pressurize section.
Entirely controlling pattern, lock control part 14 is in latched position, and nut 9 and nut seat 10 are locked together.When starting when working, melten gel motor 5 drives melten gel screw rod 3 to rotate by transmission mechanism, plastic pellet in hopper 4 is pushed and advances, plastic pellet progressively melts and pushes near loophole in gun barrel 2, along with the carrying out of melten gel, injection control system controls the back pressure value that injection motor 7 sets according to the magnitude of back pressure of sensor measurement and host computer, is controlled the size of actual back pressure by the reverse rotation (i.e. nut 9 and nut seat 10 direction of retreat) of injection screw mandrel 6; While control back pressure, nut 9 implements compressed energy-storage, after melten gel completes by nut seat 10 pairs of Compress Springs 8, after the disk body of nut seat 10 crosses the bayonet socket of trigger component 11, melten gel and back pressure control cut-off, as shown in Figure 5, ready for entering the injection stage; In the injection stage, control system operation injection motor 7 carries out injection action, operating trigger assembly 11 discharges the elastic potential energy of elastic energy storage assembly simultaneously, now exerting oneself of injection motor 7 superposes with exerting oneself of elastic energy storage assembly, promote injection action, as shown in Figure 6, in this course, injection speed and pressure whole process controlled.After injection terminates, system proceeds to holding pressure control, and the thrust of elastic energy storage assembly deducts the thrust that (or adding) injection motor 7 exports and is packing pressure; After pressurize terminates, the mould 1 of injection machine is carried out to the actions such as die sinking, pickup (ejecting), matched moulds, pressurize working cycles that injection mechanism enters next melten gel---injection---.
If the maximum thrust that injection motor 7 and injection screw mandrel 6 can provide is F
m, the thrust needed for back pressure controls is F
b(general F
m> > F
b), then the maximum compression of the elastic energy storage mechanism allowed is F
m-F
b.Under full control pattern, when injection is carried out, injection motor 7 is 2F with the thrust sum of elastic energy storage mechanism
m-F
b, thus achieve the injection thrust larger than traditional structure.If injection resistance is F
z, the quality of injection motion is M (the inertia conversion of rotating mechanism is the quality of parallel moving mechanism), then injection peak acceleration is (2F
m-F
b-F
z)/M.Due to the inertia of the moving component of this structure and traditional structure very nearly the same, therefore injection peak acceleration is significantly improved.
As a distortion of full control pattern, at the end of melten gel, if proceed to injection process immediately, can operating trigger assembly 11, namely nut seat 10 does not pause, and injection motor 7 directly starts injection action, and elastic energy storage assembly transfers to discharge the energy stored immediately.
In half control pattern, lock control part 14 is in an open position, and nut 9 and nut seat 10 are thrown off, and as nut 9 moves to injection direction, then throws off the disk body of nut seat 10 and enters cylindrical shell, as nut 9 is mobile to injection, then drives nut seat 10 together to move in the other direction.Identical with full control pattern, while carrying out back pressure control, nut 9 implements compressed energy-storage by nut seat 10 pairs of Compress Springs 8.When melten gel completes, the decrement of Compress Spring 8 reaches predetermined value, and after the disk body of nut seat 10 crosses the bayonet socket of trigger component 11, melten gel and back pressure control cut-off, as shown in Figure 2, ready for entering the injection stage.First, injection motor 7 drives injection screw mandrel 6 to rotate, and makes nut 9 move forward to predetermined decelerate position in the cylindrical shell of nut seat 10, as shown in Figure 3, secondly, control system operating trigger assembly 11, Compress Spring 8 transient burst of energy, promote nut seat 10 and melten gel screw rod 3 acceleration advance, after speed raises, injection resistance increases, and reaching a kind of balance, this stage injection speed depends on the elastic force of elastic energy storage assembly, injection resistance, the inertia of motion (not containing injection screw mandrel 6, nut 9, injection motor 7) and the time of motion completely, when nut seat 10 move to contact with nut 9 time, as shown in Figure 4, injection motor 7 is in zero-speed (also can the be set as low-speed forward) stage, the contact of the two will form a kind of impact, an impact resistance is formed to nut seat 10, this impact resistance is together with injection resistance, add the power output (power of now injection motor 7 output is contrary with injection direction) of injection motor 7, common acquisition is injection reduction of speed gradient faster, until injection completes proceed to holding pressure control, the power output (injection in the other direction) that now elastic force (injection direction) of elastic energy storage mechanism deducts injection motor 7 equals dwell pressure, the pressure precision of pressurize implements closed-loop control by the controller of injection motor 7 according to sensor feedback.After pressurize terminates, the mould 1 of injection machine is carried out to the actions such as die sinking, pickup (ejecting), matched moulds, pressurize working cycles that this injection mechanism enters next melten gel---injection---.
Under half control pattern, the maximum thrust that same injection motor 7 and injection screw mandrel 6 can provide is F
m, the thrust needed for back pressure controls is F
b(general F
m> > F
b), then the maximum compression of the elastic energy storage mechanism allowed is F
m-F
b.When injection is carried out, the thrust of energy mechanism of elasticity village is F
m-F
bif injection resistance is F
z, the quality of injection motion is M (the inertia conversion of rotating mechanism is the quality of parallel moving mechanism), then injection peak acceleration is (F
m-F
b-F
z)/M.Because under half control pattern, the moving-member of injection mechanism does not comprise injection motor 7 and injection screw mandrel 6, therefore still may realize injection peak acceleration faster under the promotion of elastic energy storage mechanism.
Under full control or half control pattern, if require larger injection acceleration, can move behind trigger component 11 position, to strengthen the decrement of elastic energy storage mechanism; If require to adjust the position that most high rate of fire occurs, then the position adjustments of motor 13 can be regulated to realize by regulating trigger motor 12 and precompressed.If require larger injection amount under half control pattern, then can along the preset deceleration position of injection direction adjusting nut 9.
