On path, launched portion is provided between the drive division and sliding block, the launched portion is fixedly connected with push rod, and the drive division is with pushing away
Go out portion and be connected by the way that the elastomeric element of release driving force can be provided for push rod, the slide rail, which is provided with, can limit release position
The limiting unit of shifting.
As the further improvement of such scheme, the sliding block is connected with drive division by transmission connection piece, described
Launched portion is slidably connected on transmission connection piece.
As the further improvement of such scheme, the elastomeric element is disk spring, and the disk spring is set in biography
On follower link.
As the further improvement of such scheme, butterfly spring can be protected by being additionally provided between the drive division and launched portion
Limited post.
As the further improvement of such scheme, the sliding block, which is provided with, to drive launched portion in sliding block extraction
Release post.
The beneficial effects of the utility model：The utility model is by the way that sliding block and drive division are connected, and push rod is with releasing
Portion is fixedly connected, when mould resets, and the elastomeric element between drive division and launched portion is compressed and saves certain elastic potential
Can, when mould core pulling, elastomeric element release elastic potential energy and to launched portion provide one with driving force in the opposite direction it is reverse
Driving force so that push rod is released, stability when improving mould core pulling with reset, and the structure of mould is optimized, reduce
Cost of manufacture and maintenance cost.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is that the utility model mould resets completion schematic diagram；
Fig. 2 is that the utility model mould core pulling completes schematic diagram.
Embodiment
Sliding block ejecting mechanism as shown in Figure 1-2, hydraulic jack 7, slide rail 1, slide block assembly 2, the slide block assembly 2 includes
Sliding block 21, push rod 22 and drive division 23, the hydraulic jack 7, drive division 23, sliding block 21 are connected successively, i.e. hydraulic jack 7
Driving drive division 23 is moved, and subsequent drive division 23 is moved with movable slider 21, and the sliding block 21, which slides laterally, to be connected on slide rail 1,
The drive division 23 has the stroke of lateral displacement, and the slide rail 1 is located on the path of the displacement of drive division 23.Drive division 23 is with sliding
Launched portion 3 is provided between block 21, launched portion 3 is fixedly connected with push rod 22.Drive division 23 is with launched portion 3 by that can be push rod 22
The elastomeric element for providing release driving force is connected, and slide rail 1, which is provided with, can limit the limiting unit of the displacement of launched portion 3.When mould is multiple
During position, the elastomeric element between drive division 23 and launched portion 3 is compressed and saves certain elastic potential energy, when mould core pulling,
Elastomeric element discharges elastic potential energy and provides a reverse actuating force in opposite direction with driving force to launched portion 3 so that push rod
22 release, stability when improving mould core pulling with reset, and optimize the structure of mould, reduce cost of manufacture and dimension
Protect cost.
It is preferred that, sliding block 21 is connected with drive division 23 by transmission connection piece, and drive connection is mutually put down to be some
Capable cylinder, cylinder two ends are respectively fixedly connected with sliding block 21 and drive division 23.4 arrangement balancings are chosen in all cylinders
Cylinder as guide pillar, launched portion 3 is slidably connected on guide pillar.
It is preferred that, elastomeric element is disk spring 4, and disk spring 4 is set on the guide pillar of above-mentioned selection.Disk spring 46
Rigidity is big, and buffering vibration absorption ability is strong, can bear big load with small deformation, can save certain gesture after load deformation is born
Energy.
It is preferred that, the limited post 5 of butterfly spring can be protected by being additionally provided between drive division 23 and launched portion 3.Limited post 5 was both
