Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to the slide block device that a kind of band ejects in advance, as shown in figure 1, including oil cylinder 1, oil cylinder
Fixed seat 2 and sliding block 6, one end middle part of described oil cylinder fixing base 2 are provided with rectangular indentation 12 vertically, and the rectangular indentation 12 is open
Both sides take-up housing 5 is installed, the other end of described oil cylinder fixing base 2 is provided with oil cylinder 1, and the piston rod of the oil cylinder 1 is horizontal
The sliding block 6 being slidably connected through oil cylinder fixing base 2 and two take-up housings 5 is connected, and is provided with described rectangular indentation 12
Top plate 4, the top plate 4 are enclosed on the piston rod of oil cylinder 1, and the side of described top plate is disposed with several horizontal through sliding block 6
Thimble 7, the length of the top plate 4 is more than the distance between two take-up housings 5 and the length of top plate 4 is less than in the both sides of rectangular indentation 4
The distance between wall, closing piece 3 is symmetrically installed with the inwall of the described both sides of rectangular indentation 12, one end of the closing piece 3 is close to sliding
The side of block 5 is provided with arc surface, and the other end of described closing piece 3 passes through spring and the closing piece of side through oil cylinder fixing base 2
Fixed seat 9 is connected, and described sliding block 6 is provided with the jacking block bar 11 to match with closing piece 3, the jacking block bar 11 close to the side of oil cylinder 1
One end passes through top plate 4, and when die casting, the piston rod of oil cylinder 1 is in elongation state, and the side of top plate 4 leans against the side of take-up housing 5
On wall, the opposite side of top plate 4 is withstood by closing piece 3, and one end of thimble 7 and sliding block 6 is extend into die cavity, sliding block 6 and top plate 4
Between gap be present, opened when die casting finishes rear mold, the piston rod of oil cylinder 1 shrinks, and sliding block 6 separates with the product of shaping
Jacking block bar 11 gradually pushes up unlocking block 3 simultaneously, and top plate 4 and thimble 7 are motionless, and after sliding block 6 contacts with top plate 4, jacking block bar 11 pushes up completely
