Embodiment
In order that the purpose of this utility model and advantage are more clearly understood, the utility model is entered with reference to embodiments
Row is illustrated.It should be appreciated that following word is only to describe one or more of specific embodiments of the present utility model,
Considered critical is not carried out to the protection domain of the specific request of the utility model.
The technical scheme that the utility model is taken as shown in Figure 1 and Figure 2, a kind of secondary the pushing away of external screw thread Plastic Injection Mould tool
Go out mechanism, including dynamic model, cover half and ejecting mechanism, the ejecting mechanism includes the first ejecting device set gradually from top to bottom
With the second ejecting device, first ejecting device includes the first push pedal 16, be fixedly mounted in first push pedal 16 the
One ejector pin retaining plate 15 and the first push rod 5 on first ejector pin retaining plate 15, the top of first push rod 5
Directly contacted with the bottom surface for breathing out furan sliding block 9；Second ejecting device includes the second push pedal 14, is fixedly mounted on the second push pedal 14
On the second ejector pin retaining plate 12 and the second push rod 17 on second ejector pin retaining plate 12, second push rod
17 are passed through inside core 10, and the top of second push rod 17 is directly contacted with external screw thread plastic 18；First push rod is consolidated
It is additionally provided with the push pedal 14 of fixed board 15 and second on resistance gauge 2, first ejector pin retaining plate 15 and stop is provided with by screw
Block 3；The dynamic model includes being provided with cushion block 4, the pad by screw on Bottom clamp plate 1 and moving platen 21, the Bottom clamp plate 1
Block 4 is provided with the groove 41 matched with the scotch 3 close to the side hypomere of scotch 3；First, second push pedal is consolidated
Fixed board and first, second push pedal are slidably mounted on push pedal guide pillar 11 respectively by ejector guide pillar 13.
The cover half includes top clamping plate 7, solid plate 6, centring ring 8 and sprue bush 19, and the top clamping plate 7 is fixedly mounted
In the top of the solid plate 6, the sprue bush 19 is arranged in the solid plate 6 and the corresponding through hole of top clamping plate 7, and
The centring ring 8 is arranged on 19 on the sprue bush by the top clamping plate 7.
More specifically scheme is that first push rod 5 is the push rods of φ 8, and second push rod 17 is the push rods of φ 4；And institute
Resistance gauge 2 is stated for nylon resin shutter.
During concrete operations, after injection pressurize cooling, injection mold is first from main parting line parting.Injection mold molds wink
Between, in the presence of spring knock pin 20, it is ensured that the Kazakhstan furan sliding block 9 of dynamic model side remains static, external screw thread plastic 18 is because of cooling
The package power of contraction is forced to stay on core 10.Afterwards, after external screw thread plastic 18 and Kazakhstan furan sliding block 9 follow moving platen 21 together
Move, after injector push rod is contacted with the second push pedal 14 of injection mold ejecting mechanism, injection mold starts to release for the first time.
Under the resistance of nylon resistance gauge, the first ejecting device and the motion of the second ejecting device mutual association, the second push rod 17 and Kazakhstan furan are slided
