Specific embodiment
The die casting of the present embodiment is as shown in Figure 1, include upper die holder 1 and lower die holder 2, upper die holder 1 is equipped with sprue gate
3, potting syrup enters mould inside from sprue gate 3, and product can be obtained after fluid injection molding to be poured.Die casting removes upper die holder 1
Afterwards as shown in Fig. 2, being equipped with mold base 4 and demoulding control mechanism, mould between the upper die holder 1 in Fig. 1 and lower die holder 2 as can be seen from Figure 2
Embryo 4 is fixedly mounted on upper die holder 1.Fig. 3 is the office of the demoulding control mechanism of the line A-A along Fig. 2, mold base 4 and part lower die holder 2
Portion's cross-sectional view, in Fig. 3, left side is front end, and right side is rear end.After the molding of product 5 between mold base 4 and lower die holder 2, mold base 4
Between demoulding control mechanism, which includes driving unit and demoulding unit, and the driving unit includes shovel base 6
With two inclined guide pillars 7, the demoulding unit includes sliding block core 8, latch plate 9, slide 10, liftout plate 11, back-end block 12 and two
Thimble 13, wherein the temporary ejection device of liftout plate 11, back-end block 12 and two composition demoulding units of thimble 13.Shovel base 6 and inclined guide pillar
7 are fixedly mounted on the lower section of upper die holder 1, and upper die holder 1 moves up, drive shovel base 6 and inclined guide pillar 7 synchronize move up, shovel base 6
Equipped with the first inclined-plane, towards left, slide 10,7 inclined direction of inclined guide pillar and shovel base 6 are injected in the inclination of inclined guide pillar 7 on first inclined-plane
The first inclined-plane it is identical, i.e. 7 upper end of inclined guide pillar is to the left, and lower end is to the right, and slide 10 can be mobile relative to inclined guide pillar 7.Sliding block core
8, latch plate 9 and slide 10 this three be fixedly connected sequentially from left to right based on structure, which is located on lower die holder 2
It can move left and right just and with respect to lower die holder 2；The product 5 of moulding by casting is pushed up in the left side of main structure, that is, sliding block core 8 left side
It is equipped with the second inclined-plane on the right side of the side wall of mold base 4, right side, that is, slide 10 of main structure, which inclines
Rake angle is all identical as shovel the first inclined-plane of base 6；Cavity is between latch plate 9 and slide 10, liftout plate 11 is located at the inner cavity
Keep right and position and can be moved left and right in cavity, set that there are two spring 14,14 one end of spring between liftout plate 11 and latch plate 9
9 right side of connecting spring plate, the other end connect 11 left side of liftout plate, and such 11 opposing cavities of liftout plate will compress when being moved to the left
Spring 14, the reset of spring 14 just will drive 11 opposing cavities of liftout plate and move right；Spring 14 can also one end connection liftout plate 11
Right side, the other end connect slide 10 left side, when such 11 opposing cavities of liftout plate are moved to the left will extension spring 14, bullet
The reset of spring 14 just will drive 11 opposing cavities of liftout plate and move right.Thimble 13 is fixedly mounted after passing through sliding block core 8 and latch plate 9
In the left side of liftout plate 11, the right side opening of slide 10 is equipped with opening, and back-end block 12 is embedded in the opening, passes through opening and liftout plate
11 right side is fixedly connected, and back-end block 12 can be moved left and right with respect to slide 10, so that liftout plate 11 be driven to move left and right.Rear end
The rightmost side face of block 12 is vertical plane, and vertical plane is equipped with third inclined-plane 15, the of 15 inclined direction of third inclined-plane and shovel base 6
One inclined-plane is identical, but 15 front end of third inclined-plane is without departing from the second inclined-plane of slide 10.The first inclined-plane of base 6 is shoveled in opposite rear end block
12 position is equipped with notch 16, which is equipped with vertical plane 17, and the vertical plane 17 withstands back-end block when die casting is closed
12 vertical plane, and the bottom of the vertical plane 17 shoveled on base 6 is bonded with the bottom of the vertical plane in back-end block 12.
After 5 moulding by casting in die casting of product, worker operation upper die holder 1 moves upwardly so that upper die holder 1 under
Die holder 2 is opened to demould to product, and mold base 4 follows upper die holder 1 to move up at this time, and upper die holder 1 drives shovel base 6 and tiltedly leads
Column 7, which synchronizes, to move up, then shovels between base 6 and slide 10 and generate gap, so that demoulding unit can move right, and inclined guide pillar
7 can apply the power of an oblique upper right in the moment moved up to slide 10, because main structure is under gravity not
Inclined guide pillar 7 can be followed to move up, so main structure can deviate to the right under the action of the power of the application of inclined guide pillar 7, i.e., tiltedly led
Column 7, which moves up, to drive main structure to move right.Main structure move right so that sliding block core 8 be detached from product 5, at this time after
The rear end face on the right side of end block 12 withstand on it is motionless on the vertical plane 17 of shovel base 6 so that liftout plate 11 and thimble 13 are motionless, thimble
13 is motionless, withstands product 5, and product 5 is made main structure will not to be followed to move right to deform or be broken.9 meeting of latch plate
Main structure is followed to move right, the spring 14 between such latch plate 9 and liftout plate 11 will be compressed.When upper die holder 1 to
When the height of upper movement is more than the vertical plane height of back-end block 12, the vertical plane of back-end block 12 is no longer by the vertical plane 17 of shovel base 6
It withstands, the reset of spring 14 at this time flicks to the right liftout plate 11, and liftout plate 11 pushes back-end block 12 and thimble 13 is driven to move right
It is dynamic, so that thimble 13 is detached from product 5, consequently facilitating worker takes out product 5 from die casting.In above-mentioned knockout course,
Inclined guide pillar 7 is inserted in always in slide 10, and such inclined guide pillar 7 moves up and main structure can be driven to move right, inclined guide pillar 7 to
Lower movement can drive main structure to be moved to the left.
After completing above-mentioned movement and taking out product 5, worker operation upper die holder 1, which moves down, drives mold base 4, shovel 6 and of base
Inclined guide pillar 7 moves down, and shovels base 6 and inclined guide pillar 7 moves down, and demoulding unit is driven to be moved to the left until die casting is complete
Closure, the first inclined-plane of third inclined-plane 15 and shovel base 6 cooperates at this time, and temporary ejection device is enable swimmingly to be moved to the left reset,
Until the preceding upper end on third inclined-plane 15 does not exceed the second inclined-plane of slide 10 backwards.Worker can be poured again after die casting closure
Product repeats above-mentioned knockout course after the formed product being poured again, that is, the production process of product may make to go on smoothly.
