Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described, But the present invention is not limited to these embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of anti-tenesmus mechanism being used in workpiece ejection process, including:
Cover half 100, it is vertically arranged, and is provided with die cavity 110 on the cover half 100, and the opening of the die cavity 110 is towards lateral Set;Knock-pin 200, its transverse direction are located on the cover half 100, workpiece to be ejected from the die cavity 110;Support group Part, it is arranged on the cover half 100 to be used to contradict with the lower surface of workpiece and connected, and the support component ejects towards workpiece Direction extends.
The anti-tenesmus mechanism is applied on mould, and the mould is the structure of lateral ejection workpiece, in simple terms, just It is that cover half 100 is located at the left and right sides respectively with dynamic model, and dynamic model moves towards cover half 100, so as to realize matched moulds.
Workpiece is after die sinking, in die cavity 110, now needs to eject workpiece, and workpiece can fall after ejection, So as to cause the accident.
And there is provided after support component, when workpiece ejects, its center of gravity is still in support component, so as to by support component Prop up, thus effectively workpiece can be avoided to drop.
For further, workpiece is laterally ejected, weight high workpiece big in particular for volume, traditional upward top The mechanism gone out, it is not very applicable, that is the not only pickup after it the is ejected because structure ejected upwards is for the big workpiece of weight Inconvenience, and ejection is very painstaking.
And after being applicable the mode of lateral ejection, due to being ejected to side, so can eliminate the gravity of workpiece influences, Make ejection more laborsaving, and support component can be good at supporting the weight of workpiece itself, avoid dropping so that whole mould Tool is especially suitable for processing the heavy weight workpiece of large volume, and after processing, pickup is also convenient for, and reliability is higher, and workpiece will not Tenesmus.
As shown in Figure 1, Figure 2, Figure 3 shows, on the basis of above-mentioned embodiment, for the anti-lower air crash in workpiece ejection process Structure also includes base 300 and contiguous block 400, and the base 300 is located at the side of the cover half 100, the contiguous block 400 one end is connected the other end with the base 300 and is connected with the cover half 100, the base 300 and the cover half 100 it Between formed with movable inner chamber.
Base 300 is mainly used for supporting cover half 100 with contiguous block 400, wherein, contiguous block 400 is used for cover half 100 Linked together with base 300, what deserves to be explained is, base 300 is platy structure, and it is vertically arranged herein.
Some ejecting mechanisms are preferably provided with movable inner chamber, bumper assembly can also be set.
Preferably, contiguous block 400 is rectangular block structure, and it is located at the edge of cover half 100, so as to ensure cover half 100 with The reliability connected between base 300.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, on the basis of above-mentioned embodiment, the support component includes extension 500 and the support column 600 of bar shaped, the lower end of the extension 500 and the cover half 100 be wholely set, the support column 600 It is arranged on the extension 500, and one end of the support column 600 is connected the other end towards workpiece top with the cover half 100 The direction gone out.
Extension 500 is exactly the projection that the lower end of cover half 100 extends outward, and the upper surface of extension 500 Shape and the shape adaptation of workpiece lower surface, it is preferred that the lower end cross section of workpiece is similar to V-type, like this, extension 500 be to tilt down structure, such extension 500, while playing a supporting role, can not interfere with the top of workpiece Go out, avoid producing interference with workpiece.
After support column 600 can make the scope that workpiece leaves extension 500, additionally it is possible to certain support is obtained, so as to anti- Only drop, and when workpiece is located on support column 600, its pickup is more convenient.
As shown in Figure 1, Figure 3, on the basis of above-mentioned embodiment, being provided with the movable inner chamber can be in the cover half Movable push pedal 310 between 100 and the base 300, the knock-pin 200 are arranged in the push pedal 310, the knock-pin 200 may pass through the cover half 100 and be ejected from the die cavity 110.
Movable push 310 can be movable between cover half 100 and base 300, that is, is moved in movable inner chamber, ejects Bar 200 is connected with push pedal 310, and when push pedal 310 is released, knock-pin 200 can be through die cavity 110, so as to which workpiece be ejected.
Preferably, the bottom of push pedal 310 is provided with attachment screw, and attachment screw passes through push pedal 310 and the end of knock-pin 200 Portion connects, so as to which knock-pin 200 is fixed in push pedal 310.
As shown in figure 3, on the basis of above-mentioned embodiment, the end of the knock-pin 200 is located at the die cavity 110 It is interior, and be fixedly connected with workpiece.
Knock-pin 200 is fixed with workpiece, so can further play the effect for preventing from falling, it is preferred that ejection Bar 200 pierces into the rear end of workpiece, and screw is provided with workpiece, and screw is threadedly coupled after being screwed into workpiece with knock-pin 200, so that Knock-pin 200 is fixed together with workpiece, can so play the effect of double insurance, only after screw is back-outed, workpiece with Knock-pin 200 separates, and can remove workpiece, and like this, knock-pin 200 also plays fall arrest effect.
As shown in Figure 1 and Figure 2, on the basis of above-mentioned embodiment, the quantity at least two of the support column 600, and Formed with the gap for being easy to pickup between two support columns 600.
Preferably, the quantity of support column 600 is two, and two support columns 600 are symmetrically set on the center line of cover half 100 Put, in pickup, because workpiece weight and volume are larger, so when dropping on support column 600, can be from two support columns Gap location between 600 carrys out pickup, furtherly, exactly withstands the bottom of workpiece from gap location by special instrument or worker Portion, then workpiece is removed from support column 600.
As shown in Figure 2 and Figure 3, on the basis of above-mentioned embodiment, guide rod 320 is provided with the base, it is described to lead The push pedal 310 is passed through to bar 320.
Guide rod 320 can guide push pedal 310 to move, and make push pedal 310 in movement, more stable, and knock-pin 200 Precision it is higher.
As shown in Figure 1, Figure 2, Figure 3 shows, on the basis of above-mentioned embodiment, mounting hole is offered on the contiguous block 400 410, the mounting hole 410 is provided at both ends with least two screwed hole (figures for corresponding to the base 300 and cover half 100 respectively In be not drawn into), the fixing screws with the cover half 100 and the base 300 are respectively arranged with two screwed holes 420, and the contiguous block 400 is connected by the fixing screws 420 with the cover half 100 and the base 300.
This connected mode, it is very hidden ingenious, base 300 can be realized using two shorter fixing screws 420 With being indirectly connected with for cover half 100.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led 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.
