Embodiment
Fig. 1-6 show related description figure of the present invention；A kind of double cast gate combination running gate system injection mold, including sprue bush
1st, upper clamping plate 2, slide A plates 3, spacing controlling organization 4, take out sliding block 5, indent mold insert 6, core 7, dynamic model B plates 8, mould in indent
Pin 9, die shoe plate 10, thimble cover plate 11, thimble push plate 12, rubbish nail 13, limited block 14, thimble 15, support column 16, die cavity are led
Post 17, die cavity guide pin bushing 18, release link 19, buckle slide block 20, elastic plastic 21, T-slot tapered wedges 22, bearing type die set guide pin 23, mould bases are led
Set 24, as shown in Figure 4.
The spacing controlling organization 4 be installed on upper clamping plate 2, slide A plates 3, on dynamic model B plates 8 to control three blocks of plates it
Between sequential mold opening；T-slot tapered wedges 22 are installed on upper clamping plate 2, drive the motion that sliding block 5 is taken out in indent；Buckle slide block
20 are installed on dynamic model B plates 8, for the side core-pulling to product buckle；Limited block 14 is installed on push pedal cover plate, control product ejection
Distance；Bearing type die set guide pin 23, mould bases guide pin bushing 24 are used for the reset for controlling mould bases；Die cavity guide pillar 17, die cavity guide pin bushing 18 be used for control and
Ensure the accuracy that die cavity resets, as shown in Figure 5.
The mold cooling system is pipeline water-cooled cooling system, pipe diameter 8mm；Sprue bush 1 is filled using three template dies
Mouth formula sprue bush；Mold parting surface is two-time parting face mode.
The structure composition of the spacing controlling organization 4 includes spacing control cutting 25, B plates locking plate 26, croze 27, cutting gear
Block 28, mobile horizontal bolt 29.Its installation situation is that spacing controls cutting 25 to be installed on top clamping plate, croze 27, cutting block 28
It is installed on A plates, B plates locking plate 26 is installed on dynamic model B plates, and mobile horizontal bolt 29 is installed in croze 27, as shown in Figure 6.
The mould structure uses false Three-board-mould structure, and Design of Runner System uses two level casting program, and one-level cast is adopted
With Subsidence pouring, two level uses U-shaped runner side gate mode, as shown in Figure 2.
The mold layout is that a mould goes out two chambers, as shown in Figure 3.
During real work, as shown in Fig. 4, Fig. 5, Fig. 6, it is as follows that it moves operation principle：
1）Mould parting control structure parts are as shown in figure 5, it is upper clamping plate, A plates, B template core patterns that it, which forms situation,
Chamber guide pillar guide pin bushing, guide-post of die-set guide pin bushing, fixed-distance controller, lower link bar, elastic plastic.Spacing control is main to implement upper clamping plate, A
Separation control between plate, B plates, is mainly used in PL1 die joints, PL2 die joints separate；
2）First time parting is between top clamping plate and A plates, i.e. PL1 die joints in Fig. 5, due to T-slot tapered wedges 22
It is installed on top clamping plate, it is impossible to it is mobile, therefore after the first parting is opened, T-slot tapered wedges 22 are driven in indent by T-slot and taken out
Sliding block 5 is to inner core pulling product I, the core_pulling demoulding at II positions；
3）Second of parting is between A plates and B plates, i.e. PL2 die joints in Fig. 5；During second of parting, product 1,2,3,
Angle Pin sliding block core-pulling mechanism dynamic model side slide at 4 under the Angle Pin effect on A plates, realize everywhere by band movable slider
The side core-pulling of snapped-in position.
Mold actions process includes following steps：
1）The opening of PL1 die joints, after injection cooling, mould is opened, and elastic plastic 21 pushes away upper clamping plate 2 and slip A plates 3
Open, A plates retreat with dynamic model B plates under fixed-distance controller control, effect of the sliding block 5 in T-slot tapered wedges 22 is taken out in indent
Under, realize core pulling action；
2）PL2 die joints are opened, and A plates, B plates have the clamping mechanism control between two plates to take out sliding block 5 in indent and realize core pulling
Afterwards, rushed open by the set of fixed-distance controller, realize the separation of A, B plate, the time of releasing, A plates continue to retreat with B plates, retreat one
After segment distance, A plates are held by fastening and the lower link bar on top clamping plate, it is impossible to which continuation retreats with dynamic model B plates again, so as to real
Existing PL2 parting.
Fig. 6 is the structure chart of spacing controlling organization 4, and each part is that spacing controls cutting 25, B plates locking plate 26, croze in figure
27th, cutting block 28, mobile horizontal bolt 29；Its installation situation is that spacing controls cutting 25 to be installed on top clamping plate, croze 27, is inserted
Bar block 28 is installed on A plates, and B plates locking plate 26 is installed on dynamic model B plates, and mobile horizontal bolt 29 is installed in croze 27；
Its operation principle is：During first time parting, mobile horizontal bolt 29 and B plates locking plate 26 pin A plates, B plates, treat for the first time
After parting, slide A plates 3 and continued to move to together with croze 27, cutting block 28, mobile horizontal bolt 29, until spacing controls cutting
25 bottom boss positions, which hit croze 27 from the right, hits the left side, so as to the locking for forming the horizontal bolt 29 of movement and B plates locking plate 26
Open, realize the separation of A plates, B plates.
3）When resetting, closed at the present PL2 die joints of mould, be then PL1 closures, last mould closes completely
Close, wait the beginning of next injection cycle.
Specific embodiment described herein is only the technology neck belonging to the present invention to spirit explanation for example of the invention
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
