Convenient disassembly when repairing replacement components, can satisfy the demand that crosshad shoe has biggish sliding stroke.Therefore, this is practical new
Type has substantive features and progress compared with prior art.
Detailed description of the invention
The related details and working principle of the embodiments of the present invention and embodiment are described with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the schematic perspective view of the utility model.
Fig. 4 is the schematic perspective view of another angle.
Specific embodiment
Referring to attached drawing, it includes crank device 1, ten that crank block, which adds double-toggle to combine transmission mechanism, in present embodiment
Prefix sliding block 2 and toggle device 3.
Crank device 3 includes preceding crank 4 and rear crank 5, and preceding crank 4 is arranged by front rotary shaft 41 in preceding mounting base 42
On, rear crank 5 by rear shaft 51 be arranged in rear mounting base 52, front rotary shaft is coaxially set with rear shaft, preceding mounting base and
Corresponding bearing will be set between front rotary shaft, corresponding bearing will be also set between rear mounting base and rear shaft, and front rotary shaft is with after
Shaft will rotate in corresponding preceding mounting base and rear mounting base respectively.
Pin shaft 6 is equipped between preceding crank 4 and rear crank 5, front rotary shaft 41 and rear shaft 51 will during synchronous rotation
Crank 4 and rear crank 5 rotate synchronously before driving, and pin shaft 6 is hinged with rocking bar 7, and rocking bar 7 and crosshad shoe 2 are hinged, and crosshead is sliding
The setting of block 2 slides lifting on guiding slide bar 8.Pin shaft 6 drives rocking bar 7 to act during preceding crank and rear crank rotate,
Rocking bar drives crosshad shoe lifting carriage on guiding slide bar 8.Front rotary shaft or rear shaft and motor (such as servo motor) are driven
The transmission connection of retarder 12 can also be arranged in connection between motor and shaft.
Toggle device 3 is respectively set at left and right sides of crosshad shoe, toggle device 3 includes the upper connecting rod being hinged
31 and lower link 32, the upper connecting rod 31 of left and right sides toggle device 3 and the hinged place of lower link 32 are respectively articulated with intermediate connecting rod 33,
Intermediate connecting rod 33 is respectively hinged at the left and right sides of crosshad shoe 2.Crosshad shoe leads to respectively during lifting carriage
Crossing intermediate connecting rod 33 drives the transmission of toggle device 3 mobile mold base 9 of two sides to move up and down, and mobile mold base 9 is moved up and down and fixed
