Description
Technical field
The present invention relates to mold design technical field, more particularly to a kind of realize what spot pouring mouth waste material safely, conveniently came off
Injection mold.
Background technology
In mould, the connection area of spot pouring mouth and working of plastics is smaller, therefore is easier to separate them while die sinking, and
Deviate from respectively from mould, this mould structure is conducive to improving production efficiency and the security of Mould operation, realize automatic raw
Production.The de- material mould of common spot pouring mouth includes following two：
First, typical three template die
As shown in fig. 1, during die sinking by stage clip elastic force reply, A-A faces parting is opened, due to nozzle of injector
It is molten plastic with sprue bush connecting portion, therefore after the parting of A-A faces, cast gate waste material must stay in spot pouring mouth taper hole with cavity plate
In；With proceeding for die sinking, when spacer pin 01 and the left side of draw ring 02 are collided, A-A faces parting terminates, B-B immediately by
Open；After B-B partings are finished, arm need to be stretched into A-A faces spot pouring mouth waste material is pressed from both sides out with pliers；Such operation is significantly greatly increased
Labor intensity.
2nd, draw-ring type spot pouring mouth automatic stripping die
As shown in Figure 2, during die sinking, C-C faces are first opened, and working of plastics is packed tightly by core, and with dynamic model left lateral, then
B-B die joints are opened again；Because part 03 is acted on, runner scrap is drawn out spot pouring mouth taper hole and is close to the left side of part 3；After
Continuous die sinking, due to the effect of part 04,05,06, cast gate waste material is quickly unloaded from the bulb of part 03 and voluntarily fallen by part 05；From
Understood in Fig. 2, though spot pouring mouth waste material can unload de- by cavity plate, (i.e. C-C die joints) is connected by draw ring 07 between fixed and moving mould
Connect, because draw ring can not possibly be made long enough, so during parting, fixed and moving mould can not possibly be completely separated, it is necessary to by travel switch
The start and stop moved between dynamic, cover half are realized, this just brings unsafe factor, such as operator's error or shape to machine operation
Into malfunctioning switch, the displacement between active and inactive mold can be all caused to exceed the restriction scope of draw ring, so as to cause the serious of mould
Damage；Further, since the spacing of the separation between active and inactive mold is limited by draw ring, so as to be inconvenient to take out workpiece.
The content of the invention

With reference to Fig. 3-6, the work for realizing the injection mold that spot pouring mouth waste material safely, conveniently comes off that the present invention is provided
Make principle, be further described：
1st, parting first
Under initial situation, active tongue 2 is caught on by drag hook 26, it is achieved thereby that the company of dynamic model part and fixed mold part
Connect, as shown in Figure 3；Dynamic model part is moved to left, and drag hook 26 drives fixed mold part to move to left so that fixed mold part with
Sprue bush is partially separated, and A-A die joints are opened, and completes parting first, as shown in Figure 4；Sprue bush 8 is by falling in the process
Wimble structure 801 pulls out cast gate waste material 27.
2nd, twice parting
After parting d2 distances first, the left side of fixed mold fixed plate 10 contact stop nut 16, dynamic model part is with determining
Separation can not be continued between model core segment；Dynamic model part continues to move to left, and de- material part is dragged in the presence of coupling spindle 15 left
Move, de- material part is separated with feeding part, and B-B die joints are opened, and complete twice parting, as shown in Figure 5；In the process,
Discharging ring 7 is moved to left relative to sprue bush 8, and waste material 27 is unloaded from the back taper of sprue bush 8.(note：Due to movement velocity quickly,
Therefore cast gate waste material can eject the right taper hole of sprue bush and land.)
3rd, three partings
During de- material part is separated with feeding part, pressure hook 1 is contacted with active tongue 2, and it is fixed to press against the locking of active tongue 2
In model core segment；After twice parting d1 distances, the flange 1401 of discharging axle sleeve 14 is pressed onto on the step of axle sleeve hole 401,
A-A, B-B parting all terminate, and now active tongue 2 is moved just separates with drag hook 26；Dynamic model part continues to move to left, C-C partings
Face smooth opening, dynamic model part is completely separated with fixed mold part, as shown in Figure 6.
4th, matched moulds
With the right lateral of dynamic model part, pressure hook 1 is applied to the distress resolves in active tongue 2, and movable tongue 2 departs from pressure quickly
Hook 1 and eject to uppermost position in fig-ure, the right tilted surface of drag hook 26 progressively steady pressure activity tongue 2, and be close to drawing after upspring quickly again
The right side working face (recovering to Fig. 3 original states) of hook 26.
Those skilled in the art should be understood that the present invention can be implemented without departing from this with many other concrete forms
The spirit or scope of invention.Although also have been described embodiments of the invention, it should be understood that the present invention should not be limited to these implementations
Example, make within the spirit and scope of the invention that those skilled in the art can define such as appended claims change and
