Described nut seat 10 is the structure of front end cylinder then end plate body, the nozzle of nut seat 10 cylinder in
Forming the stepped hole of size reduction on disk body, the cylinder of nut seat 10 is placed in the middle of guide post 15 (close
Gun barrel support 16), barrel front end rotates coaxially with the melten gel screw rod 3 in gun barrel 2 and is connected, nut seat 10
Offering pilot hole on disk body, described pilot hole is respectively cooperating with guide post 15 and is slidably installed；Described nut 9 is sliding
In the dynamic cylinder being installed on nut seat 10, the Step Shaft of nut 9 and the stepped hole on nut seat 10 disk body
It coincide spacing (this structure can prevent nut 9 from coming off from nut seat 10), the cylinder of nut seat 10 sets
Lock control part 14 (screw in cylinder can be screwed in and maybe can pass in and out the finger in cylinder) is had to be locked in by nut 9
Described anastomotic site, described injection screw mandrel 6 is with being located between nut 9 and injection motor 7, described
Injection screw mandrel 6 leading portion screws with nut 9, and injection screw mandrel 6 front end enters in the cylinder of nut seat 10, penetrates
Collodion silk bar 6 rear end connects the output shaft of injection motor 7；Described elastic energy storage assembly uses two or many
Compression spring 8, compression spring 8 is set with on guide post 15 and is pressed on the disk body of nut seat 10 in advance
And between injection motor cabinet 17, as shown in Figure 1.
Described trigger component 11 is located at the rear of nut seat 10 disk body, and its position can be regulated by trigger
The screw mandrel that motor 12 drives realizes forward and backward position adjustments, and nut seat 10 is moved rearwards by oppressing compression spring
8 energy storage, when the disk body of nut seat 10 crosses the bayonet socket of trigger component 11, trigger component 11 blocks spiral shell
Female seat 10 fixes it in the energy storage position set；Described precompressed adjusting part 18 is located at injection motor cabinet 17
And between compression spring 8, its position can realize forward and backward by the screw mandrel that precompressed regulation motor 13 drives
Position adjustments, can realize the pretension to compression spring 8 decrement and obtain the pretightning force of setting, such as Fig. 1
Shown in.
Injection machine working method of the present invention, have employed above-mentioned glue injecting device, can realize injection machine entirely control and
Two kinds of action patterns of half control: full control pattern is when lock control part 14 enters cylinder lock nut 9 in nut seat
Time on 10 (nut 9 and nut seat 10 form one and move integrally), injection mechanism utilizes elastic energy storage group
Part energy storage, the collaborative speed of injection motor 7 whole-process control injection process, pressure；Half control pattern is when lock
When control 14 exits cylinder and releases the locking to nut 9 (between the cylinder of nut 9 and nut seat 10
Can relatively slide), the injection that injection mechanism utilizes the energy storage of elastic energy storage assembly to carry out injection first half section is moved
Making, injection motor 7 carries out injection speed descending branch and the pressure and speed control of pressurize section.
Entirely controlling pattern, lock control part 14 is in the locked position, and makes nut 9 and nut seat 10 be locked in one
Rise.When work starts, melten gel motor 5 drives melten gel screw rod 3 to rotate, by hopper by drive mechanism
Plastic pellet in 4 pushes and advances, and plastic pellet progressively melts in gun barrel 2 and pushes near loophole,
Along with the carrying out of melten gel, injection control system controls the injection motor 7 magnitude of back pressure according to sensor measurement
The back pressure value set with host computer, by reverse rotation (i.e. nut 9 and the nut seat 10 of injection screw mandrel 6
Direction of retreat) control actual back pressure size；While controlling back pressure, nut 9 is by nut seat 10
Compression spring 8 is implemented compressed energy-storage, and after melten gel completes, the disk body of nut seat 10 crosses trigger component
After the bayonet socket of 11, melten gel and back pressure control cut-off, as it is shown in figure 5, ready for entering the injection stage；
In the injection stage, control system operation injection motor 7 carries out injection action, simultaneously operating trigger assembly 11
The elastic potential energy of release elastic energy storage assembly, now exerting oneself of injection motor 7 and going out of elastic energy storage assembly
Power superposition, promotes injection action, and as shown in Figure 6, in this course, injection speed and pressure are omnidistance
Controlled.After injection terminates, system proceeds to holding pressure control, and the thrust of elastic energy storage assembly deducts and (or adds
On) injection motor 7 output thrust be packing pressure；After pressurize terminates, the mould 1 of injection machine is entered
The actions such as row die sinking, pickup (ejecting), matched moulds, injection mechanism enters next melten gel injection
Pressurize cycle of operation.
If the maximum thrust that injection motor 7 and injection screw mandrel 6 can provide is Fm, needed for back pressure controls
Thrust is Fb(general Fm＞ ＞ Fb), then the maximum compression of the elastic energy storage mechanism allowed is Fm-Fb.?
Under full control pattern, when injection is carried out, injection motor 7 is 2F with the thrust sum of elastic energy storage mechanismm-Fb,
It is thus achieved that the injection thrust bigger than traditional structure.If injection resistance is Fz, injection motion
Quality be M (the inertia conversion of rotating mechanism is the quality of parallel moving mechanism), then injection peak acceleration is
(2Fm-Fb-Fz)/M.Owing to the inertia of the moving component of this structure is very nearly the same with traditional structure, therefore injection
Peak acceleration is significantly improved.
As the full deformation controlling pattern, at the end of melten gel, if proceeding to injection process immediately, can
Need not operating trigger assembly 11, i.e. nut seat 10 not pause, injection motor 7 directly initiates injection
Action, elastic energy storage assembly immediately then discharges the energy stored.
In half control pattern, lock control part 14 is in an open position, makes nut 9 disengage with nut seat 10, as
Nut 9 moves to injection direction, then disengage the disk body of nut seat 10 and enter cylinder, if nut 9 is to penetrating
Glue opposite direction moves, then drive nut seat 10 together to move.Identical with full control pattern, carrying out back pressure control
While system, compression spring 8 is implemented compressed energy-storage by nut seat 10 by nut 9.When melten gel completes,
The decrement of compression spring 8 reaches predetermined value, and the disk body of nut seat 10 crosses the bayonet socket of trigger component 11
After, melten gel and back pressure control cut-off, as in figure 2 it is shown, ready for entering the injection stage.First,
Injection motor 7 drives injection screw mandrel 6 to rotate so that nut 9 moves forward to pre-in the cylinder of nut seat 10
Fixed deceleration position, as shown in Figure 3；Secondly, control system operating trigger assembly 11, compression spring 8
Transient burst of energy, promotes nut seat 10 and melten gel screw rod 3 to accelerate to advance, injection resistance after speed raises
Power increases, and reaches a kind of balance, this stage injection speed depend entirely on elastic energy storage assembly elastic force,
Injection resistance, the inertia of motion (without injection screw mandrel 6, nut 9, injection motor 7) and fortune
The dynamic time；When nut seat 10 moves to contact with nut 9, as shown in Figure 4, at injection motor 7
In zero-speed (can also the be set as low-speed forward) stage, the contact of the two will form a kind of impact, right
Nut seat 10 forms an impact resistance, and this impact resistance is together with injection resistance, plus injection motor 7
Power output (power of now injection motor 7 output is in opposite direction with injection), common acquisition faster injection fall
Speed gradient, until injection completes to proceed to holding pressure control, the now elastic force (injection direction) of elastic energy storage mechanism
Deduct the power output (injection opposite direction) of injection motor 7 equal to dwell pressure, the pressure precision of pressurize by
The controller of injection motor 7 implements closed loop control according to sensor feedback.After pressurize terminates, to injection machine
Mould 1 carry out the actions such as die sinking, pickup (ejecting), matched moulds, this injection mechanism enters next melten gel
Injection pressurize cycle of operation.
Under half control pattern, the maximum thrust that same injection motor 7 and injection screw mandrel 6 can provide is Fm,
Thrust needed for back pressure controls is Fb(general Fm＞ ＞ Fb), then the maximum pressure of the elastic energy storage mechanism allowed
Contracting power is Fm-Fb.When injection is carried out, the thrust of energy mechanism of elastic village is Fm-FbIf injection resistance is
Fz, the quality of injection motion is M (quality that inertia conversion is parallel moving mechanism of rotating mechanism), then
Injection peak acceleration is (Fm-Fb-Fz)/M.Because under half control pattern, the mobile parts of injection mechanism
Do not include injection motor 7 and injection screw mandrel 6, therefore still may realize more under the promotion of elastic energy storage mechanism
Fast injection peak acceleration.
Under full control or half control pattern, if requiring bigger injection acceleration, can be by trigger component 11
Move behind position, to strengthen the decrement of elastic energy storage mechanism；If requiring to adjust the position that high rate of fire occurs
Put, then can be by the position adjustments of trigger regulation motor 12 and precompressed regulation motor 13 be realized.
If requiring bigger injection amount under half control pattern, then can making a reservation for along injection direction adjusting nut 9
Deceleration position.
