Embodiment 1
The present embodiment provides a kind of side core-pulling mechanism, as in figure 2 it is shown, include having the first of the first core 2
Slide block 1, curved pull rod the 3, second core 4 and transmission mechanism.Wherein,
Described first slide block 1 is suitable to be arranged on plastic 9 and need to loose core the horizontal direction X side of end, and described first
Slide block 1 can horizontally slip by X in the horizontal direction, and described first core 2 is fixed on described first slide block 1 also
X extends in the horizontal direction, and described first core 2 is taken out along horizontal square side for end of need to loosing core plastic 9
Core, can make described plastic 9 need to loose core end forming hole or groove by side core-pulling, becomes in described first slide block 1
Type has the oblique guide hole 11 of be suitable to coordinate with curved pull rod 3 first, and described first oblique guide hole 11 is through described
The top of the first slide block 1 and bottom and described first oblique guide hole 11 X in the horizontal direction tilt.
As shown in Figure 6 and Figure 7, described curved pull rod 3 includes straight-bar portion 31 and brace portion 32, described brace portion 32
One end connects the bottom in described straight-bar portion 31, and the other end X in the horizontal direction as free end tilts, described
Oblique and the described first oblique guide hole 11 in brace portion 32 oblique identical, the angle of inclination is the most identical.?
In the present embodiment, described first oblique guide hole 11 is sized slightly larger than the size in described brace portion 32, thus
Described brace portion 32 can either be extend in described first oblique guide hole 11 relatively easily, can make again
Described brace portion 32 is stable with being slidably matched of described first oblique guide hole 11；In the present embodiment, institute is worked as
State curved pull rod 3 when there is relative slip in the vertical direction y with described first slide block 1, described curved pull rod 3
In described brace portion 32 stretches into described first oblique guide hole 11 and slide, during reciprocatingly sliding, described
Brace portion 32 promotes described first slide block 1 X in the horizontal direction to horizontally slip, so that the first slide block 1 side
Described first core 2 complete side core-pulling action.
In order to realize plastic 9 need to be loosed core end forming hole in the vertical direction y or groove, described second core 4
It is arranged at plastic 9 and need to loose core above or below end, for plastic 9 need to be loosed core end at vertical direction Y
Side action.Described second core 4 of the present embodiment is preferably provided at plastic 9 and need to loose core the lower section of end.
Wear as it is shown on figure 3, be provided with in the described first oblique guide hole 11 of the present embodiment with described brace portion 32
Cross the vertical plane that the described straight-bar portion 31 of the described curved pull rod 3 after described first oblique guide hole 11 coordinates, described
Straight-bar portion 31 along described vertical plane slide up and down time described in the first slide block 1 X in the horizontal direction remain stationary as.
Described transmission mechanism one end is connected to described second core 4, and the other end is suitable to and passes completely through described the
The transmission mechanism that the described brace portion 32 of one oblique guide hole 11 coordinates, by means of described curved pull rod 3 and described the
One slide block 1 slides up and down relatively, and the described brace portion 32 passing completely through described first oblique guide hole 11 drives institute
State transmission mechanism action, and then drive described second core 4 vertically Y to slide up and down.
The side core-pulling mechanism of the present embodiment preparation before side core-pulling: described first slide block 1 first passes through
Its described first oblique guide hole 11 coordinates described brace portion 32 to stretch with the described brace portion 32 of described curved pull rod 3
In entering described first oblique guide hole 11 and occur relatively to slide up and down, under mating reaction, described brace portion
32 promote described first slide block 1 X in the horizontal direction to slide towards plastic 9 end of need to loosing core, until described first sliding
The first core 2 on block 1 moves to the first core 2 and described plastic 9 described in its side core-pulling position need to loose core end
Stop during portion's contact；
After the oblique guide hole that the described brace portion 32 of described curved pull rod 3 passes completely through described first slide block 1,
The straight-bar portion 31 of described curved pull rod 3 joins with the vertical plane of shaping on the described oblique guide hole of described first slide block 1
Closing, described first slide block 1 remains stationary as at this process X in the horizontal direction and (i.e. keeps the first core 2 to rest on
Side core-pulling position), the described brace portion 32 of described curved pull rod 3 coordinates the described biography of drive with described transmission mechanism
Dynamic mechanism action, described transmission mechanism action and then drive in described second core 4 vertically Y-direction sliding
Dynamic, until described second core 4 slides into its side core-pulling position, (described second core 4 needs with described plastic 9
Loose core the lower contact of end)；
The side core-pulling process of the side core-pulling mechanism of the present embodiment: the described brace portion 32 of described curved pull rod 3 and institute
Stating transmission mechanism opposite direction to coordinate, described brace portion 32 drives described transmission mechanism action, described driver
Structure and then drive described second core 4 vertically Y-direction lower slider, completes vertically side, described plastic 9 end
To Y side core-pulling, in the process, the straight-bar portion 31 of described curved pull rod 3 is along described the of described first slide block 1
The vertical plane of one oblique guide hole 11 slides, and described first slide block 1 X in the horizontal direction remains stationary as；Treat described
After second core 4 completes side core-pulling, described curved pull rod 3 continues with described first slide block 1 in the vertical direction y
Occurring relatively to slide, the described brace portion 32 of described curved pull rod 3 slides into described the of described first slide block 1
In one oblique guide hole 11, described brace portion 32 promotes described first slide block 1 X in the horizontal direction towards away from described
Plastic 9 end direction of need to loosing core slides, and described first core 2 removes from described plastic 9 end, completes described
Plastic 9 end horizontal direction X side core-pulling.
Therefore, the side core-pulling mechanism of the present embodiment can complete plastic by curved pull rod and need to loose core end
The asynchronous side core-pulling of X and vertical direction Y, simplifies injection mold structure, reduces mould in the horizontal direction
Tool cost；It addition, the side core-pulling mechanism of the present embodiment is positive drive, it is to avoid because of bullet in prior art
Spring lost efficacy and caused the risk hitting mould, improve injection mold functional reliability.
