The specific embodiment
Embodiment 1: as depicted in figs. 1 and 2, a kind of mould comprises dynamic model 100 and cover half 200 and cover half ejecting mechanism.Dynamic model 100 comprises dynamic model frame 1 and dynamic model die cavity 2, and cover half 200 comprises cover half frame 4 and cover half die cavity 5.
The die cavity of the bigger side of product package power is arranged on the cover half 200, and the die cavity of the less side of package power is arranged on the dynamic model 100.Dynamic model one side is provided with a secondary cavity 3 that cast gate (not shown) and product die cavity 14 are connected of advancing with mould.
The cover half ejecting mechanism comprises the spring bumper cover 10 of fixedlying connected with cover half frame 4, and four cover half push rods 6 that pass cover half frame 4 and cover half die cavity 5, therefore, acts on and has four auxiliary summits 15 on the secondary cavity 3.It is simultaneously corresponding with secondary cavity 3 and active and inactive mold die joint 13 that cover half push rod 6 is positioned at the end face 61 of active and inactive mold die joint 13 1 sides, and cover half push rod 6 is symmetrical arranged along the center line of secondary cavity 3.
In other specific embodiment, the end face 61 of cover half push rod 6 also can be only with secondary cavity 3 over against, and realize essentially identical function.
In other specific embodiment, according to the size of actual cover half package power, the quantity of cover half push rod 6 also can be other quantity more than two, to reach essentially identical technique effect.
Be provided with spring 9 between spring bumper cover 10 and the cover half push rod 6, the quantity of spring 9 equates with cover half push rod 6, position and cover half push rod 6 over against.When die sinking, the elastic force that cover half push rod 6 provides by spring 9 makes foundry goods separate with cover half die cavity 5.
When die casting after die casting is finished, foundry goods is in the product die cavity 14 of mould.Moving, the cover half of mould separate with the motion of die casting machine movable part, even mould is opened.At this moment, the tension force of spring 9 acts on the cover half push rod 6, makes 6 counter motions of cover half push rod, and then makes four push rods to having acted on one group of pressure on the secondary cavity 3, thereby foundry goods is separated with cover half die cavity 5.After die sinking, the program of ejecting of press were finished, foundry goods broke away from from mould fully, and moving, cover half matched moulds in next working cycles of press are waited for the working procedure of circulation next time.
Embodiment 2: as shown in Figure 3, the structure of present embodiment is substantially the same manner as Example 1, and different is that cover half push rod 6 is eight (all not illustrating among the figure), cover half frame 4 is provided with an auxiliary cavity volume 12, is provided with the push rod pressure strip 8 that is arranged in auxiliary cavity volume 12 between spring 9 and the cover half push rod 6.Push rod pressure strip 8 is provided with spring cavity volume 81 near spring bumper cover 10 1 sides, and spring 9 is a butterfly spring, is arranged in the spring cavity volume 81.
Push rod pressure strip 8 is positioned at cover half push rod 6 one sides and is provided with the push rod fixed head 7 of fixedlying connected with push rod pressure strip 8, and the end that cover half push rod 6 is arranged in auxiliary cavity volume 12 is fixed on push rod fixed head 7.
Be fixedly connected with release link 11 on the push rod fixed head 7, release link 11 passes cover half frame 4 and cover half die cavity 5 extends to active and inactive mold die joint 13.
When die casting after die casting is finished, foundry goods is in the product die cavity 14 of mould.Moving, the cover half of mould separate with the motion of die casting machine movable part, even mould is opened.At this moment, the tension force of butterfly spring 9 acts on the push rod pressure strip 8, promote push rod pressure strip 8, push rod fixed head 7 and 6 counter motions of cover half push rod, make eight cover half push rods (all not illustrating among the figure) to having acted on one group of pressure F on the secondary cavity 3, thereby foundry goods is separated, as shown in Figure 4 with cover half die cavity 5.After die sinking, the program of ejecting of press were finished, foundry goods 16 broke away from from mould fully, as shown in Figure 5.Then, moving, cover half matched moulds in next working cycles of press, this ejecting mechanism is returned to the state of Fig. 3 under the effect of release link 11, wait for the working procedure of circulation next time.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
