Specific implementation mode
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1 to Figure 3, originally there is mould structure of mandril, including moving platen 1, first is equipped with successively on moving platen 1
Sliding block 2 and the second sliding block 3 offer first through hole 4 on first sliding block 2, on the first sliding block 2 activity be inserted with pumping center device
5, taking out center device 5 has pumping rod 6, drains and is inserted in first through hole 4 and can be moved relative to first through hole 4；Mold core 7,
It is embedded at moving platen 1,7 one end of mold core offers casting gate 8；Solid plate 9 is located at 1 side of moving platen, is opened up on solid plate 9
Have several second through-holes 10, on solid plate 9 activity be inserted with ejecting mechanism 11, ejecting mechanism 11 has several mandrils 12, top
Bar 12 is inserted in the second through-hole 10 and can be moved relative to the second through-hole 10.
When molding, moving platen 1 is in close contact with solid plate 9, can transport raw material to mold core 7 by casting gate 8 at this time, this
When the first sliding block 2 in 3 slid inward of the second sliding block and make raw material be molded to product, during formed product, take out concentric mechanism
It can be moved relative to the first sliding block 2, and then pumping rod 6 can carry out pore-forming to the side of product, can thus reduce sliding block
Motion path, and can be by product one-pass molding, product does not have to carry out secondary operation again, thus this makes it possible to it is cost-effective simultaneously
And reduce manpower.
It can be molded after formed product, because having more rib on product, these ribs can stick in solid plate 9
On, cause product when die sinking that can not completely disengage solid plate 9, the damage of product can be caused on probability very big in this way, is caused into
This increase.In the application, when die sinking, ejecting mechanism 11 has mandril 12, and mandril 12 is inserted in the second through-hole 10 and energy
Enough to be moved relative to the second through-hole 10, i.e., mandril 12 can move up and down in solid plate 9, so when die sinking, mandril 12 to
Product can be ejected solid plate 9, caused by the rib avoided in product and 9 adhesion of solid plate by upper movement
The case where damage of product, saving production cost that can be largely.
Shown in as shown in Figure 1, Figure 3 and Figure 4, ejecting mechanism 11 has fixed plate 14 and movable plate 15, in fixed plate 14 uniformly
Equipped with several disc springs 16, the upper end of each disc spring 16 is all connected to 15 lower end of movable plate, and one end of each mandril 12 is fixed
In 15 upper end of movable plate.
Disc spring 16 is for providing elastic force, and when the die is closed, mandril 12 is bounced back to by outer force effect and flushed in the second through-hole 10, from
And movable plate 15 is driven to bounce back, and movable plate 15 can drive disc spring 16 to compress at this time so that and disc spring 16 generates screen resilience, this
Sample, in die sinking, mandril 12 is no longer pushed by external force, at this point, disc spring 16 is also no longer influenced by lower pressure, i.e. disc spring 16 can return
Bullet can drive movable plate 15 to move up, that is, drive mandril 12 living moves up, and at this moment, mandril 12 can be withstood on
It is ejected on product and by product, this makes it possible to the ribs avoided in product and 9 adhesion of solid plate.
It is additionally provided on solid plate 9 and resets through-hole 17, be additionally provided on movable plate 15 and reset the quite corresponding reset of through-hole 17
Bar 18,18 activity of release link, which is inserted in, to be resetted in through-hole 17.
Have in the corresponding lower pressure area 19 of release link 18 on mold core 7, and release link 18 can be resisted against lower pressure area 19.
When molding, lower pressure area 19 can be by the institute of corresponding release link 18 against and then moving platen 1 is close in solid plate 9
Contact, i.e., corresponding release link 18 can be pressed down against by the lower pressure area 19 in mold core 7, and release link 18 can squeeze downwards at this time
Movable plate 15 is pressed, so that movable plate 15 follows release link 18 to move downwardly together, when movable plate 15 moves downward, activity
Plate 15 enables to disc spring 16 to be squeezed, to which disc spring 16 can generate screen resilience.
1 one end of moving platen is installed with the first link block 20, and the first sliding groove 21 is offered in the first link block 20, and first slides
Block 2 is slidably set in the first sliding groove 21, and one end of the first sliding block 2 is equipped with the first pin rod 22.
As shown in Fig. 2, taking out center device 5 there is drive cylinder 23, pumping rod 6 to be fixedly arranged on driving unit one end, drive cylinder 23
It is fixedly arranged on the first sliding block 2,23 tail end of drive cylinder is installed with the first power unit 24.
Because the first power unit 24 is fixedly arranged on 23 tail end of drive cylinder, and because drive cylinder 23 is fixedly arranged on the first sliding block
On 2, so when the first power unit 24 provides power, the first sliding block 2 can be driven to be moved relative to the first sliding groove 21, from
And raw material are molded, after the first sliding block 2 is molded raw material, drive cylinder 23 start to work, drive pumping rod 6 into
Row movement, further can carry out pore-forming to product after the first sliding block 2 is molded raw material at this time will produce that is, before die sinking
Product are molded completely, this makes it possible to avoid secondary operation, reduce manpower and materials, and can reduce the mobile row of the first sliding shoe
Journey facilitates die sinking, while can ensure the positional precision of pore-forming again, reduces the scrappage of product, more cost-effective.
1 other end of moving platen is installed with the second link block 26, offers the second sliding groove 27 on the second link block 26, and second
Sliding block 3 is slidably connected to the second sliding groove 27.
Second sliding block, 3 tail end is equipped with the second power unit 25, and 3 front end of the second sliding block is equipped with the second pin rod 28.
Second power unit 25 is set to 3 tail end of the second sliding block, so, when the second power unit 25 works, the can be driven
Two sliding blocks 3 move, and the second pin rod 28 can be molded the another side of product at this time.
Groove 29 corresponding with the first sliding block 2 and the second sliding block 3 is offered on solid plate 9, cover half when molding in this way
Plate 9 can be complete in moving platen 1 and be closely contacted, and offers sprue 30 on mold core, sprue 30 is located at casting gate 8
One end, and penetrated through in casting gate 8, in this way in molding, raw material can be completely into in mold core 7.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
Generation, defined range that however, it does not deviate from the spirit of the invention.
