The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
See also Fig. 1 to Fig. 3, the ejection shaping die 100 of embodiment of the present invention is applied on the Jet forming machine (not shown), and it comprises gripper shoe 10, is fixed on the first die holder 20 on gripper shoe 10, the first die 30 that is installed in the first die holder 20, fixture 40, the second die holder 50, the activity on fixture 40 of being fixed on are installed in the second die 60 of the second die holder 50 and be installed in four elastic components 70 on the second die 60.
Gripper shoe 10 is fixedly connected with respectively with driven unit (not shown) and first die holder 20 of Jet forming machine, and driven unit drives gripper shoe 10 and moves, thereby drives the shuttling movement that the first die holder 20 is done mold closing and die sinking.In embodiment of the present invention, gripper shoe 10 comprises substrate 12 and is convexly set in two fixed parts 14 on substrate 12.Substrate 12 is roughly rectangular tabular, and fixed part 14 roughly is the bar shaped bulk, and two parallel substrates 12 that are convexly set in of fixed part 14 are near on the surface of the first die holder 20.
The first die holder 20 is roughly rectangular tabular, and it is fixed on two fixed parts 14 of gripper shoe 10.The first die holder 20 convexes with four locating dowels 22 of rectangular distribution away from four corners on a surface of gripper shoe 10.The centre position of the first die holder 20 is concaved be used to the mounting groove 24 of accommodating the first die 30.Mounting groove 24 is roughly rectangular, and accordingly, the first die 30 is rectangular block shape, and the appearance and size of the first die 30 is consistent with mounting groove 24.The first die 30 correspondences are contained in mounting groove 24, and fix with the first die holder 20.
Please consult simultaneously Fig. 4 and Fig. 5, the second die 60 comprises upper surface 62 and the lower surface 64 relative with upper surface 62 near fixture 40.The second die 60 correspondences are contained in the die cavity 524 of the second die holder 50, and the second die 60 is consistent with the degree of depth of die cavity 524 along the height of the depth direction of die cavity 524.Four corners of upper surface 62 are concaved with four installing holes 622 of rectangular distribution, and the step trough 5242 of corresponding the second die holder 50 of the opposite end of upper surface 62 protrudes out and is formed with two location divisions 626, and location division 626 is along the height H of the depth direction of step trough 5242
1Depth H than step trough 5242
2Smaller, so that the second die 60 has certain telescopic movable scope.In embodiment of the present invention, elastic component 70 is spring, and an end correspondence of four elastic components 70 is contained in four installing holes 622 of the second die 60.Be appreciated that elastic component 70 can also be shell fragment etc.
The quantity that is appreciated that elastic component 70 can be one, two, three or a plurality of arbitrarily.
Be appreciated that fixture 40 also can be provided with installing hole near the installing hole 622 on corresponding the second die 60 on the surface of a side of the second dies 60, so that elastic component 70 elastic telescopic between fixture 40 and the second die 60 better.
During assembling, the first die holder 20 is fixed on gripper shoe 10, and the first die 30 correspondences are fixedly installed in the mounting groove 24 of the first die holder 20, and gripper shoe 10 fixes with the driven unit of Jet forming machine; The second die 60 activities are installed in the die cavity 524 of the second die holder 50, two location division 626 correspondences are contained in two step troughs 5242 of die cavity 524, one end correspondence of each elastic component 70 is fixed in an installing hole 622, then by the locking member (not shown), the second die holder 50 is fixed on fixture 40, thereby the second die 60 is limited between the second die holder 50 and fixture 40, and the other end of elastic component 70 flexibly supports fixture 40.
During use, the first die holder 20 be placed horizontally at the second die holder 50 under, and the first die 30 and the second adjacent setting of die 60, the second die 60 is under action of gravitation, part convexedly stretches in the first surface 52 of the second die holder 50, and the height of its protrusion equals the depth H of step trough 5242
2H with location division 626
1Poor (seeing also Fig. 4).
During mold closing, driven unit drives the first die holder 20 and vertically moves to the second die holder 50, at first the first die 30 touches the second die 60, continue to advance the first die holder 20 until four locating dowel 22 correspondences of the first die holder 20 are contained in four locating holes 522 of the second die 60, in this process, the first die 30 continues to compress the second die 60 and moves towards fixture 40, until the upper surface 62 of the second die 60 supports fixture 40, elastic component 70 is contained in installing hole 622 (seeing also Fig. 5) after compression fully.Existence due to elastic component 70, the first die 30 compresses in the process of the second die 60, the active force of first 30 pairs of dies the second die 60 obtains certain buffering, weaken the impact strength between the first die 30 and the second die 60, thereby avoided the collsion damage between the first die 30 and the second die 60.
During die sinking, driven unit drives the first die holder 20 and moves along the direction away from the second die holder 50, and simultaneously, second die 60 ejection the first dies 30 move away from fixture 40 under the elastic force effect of elastic component 70, thereby are conducive to fast demoulding.
The second die 60 of ejection shaping die 100 of the present invention is movably set in the second die holder 50, and the second die 60 is provided with a plurality of elastic components 70 near a side of fixture 40, during mold closing, the elastic force of elastic component 70 acts on the second die 60, the impact that makes the second die 60 be subject to is cushioned, thereby avoids the collsion damage between the first die 30 and the second die 60; Simultaneously, during die sinking, elastic component 70 promotes the first die 30 and moves away from fixture 40, thereby is conducive to fast demoulding.
Be appreciated that gripper shoe 10 can omit, accordingly, the first die holder 20 directly and driven unit fix.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
