To 426 limition orientation of slot, so that piston rod 43 is rotated backward during moving down, when guide post 431 is moved to
When the least significant end of guide groove 426, piston rod 43 rotates backward 90 degree of resets, and the claw 41 for being fixed on 43 top of piston rod drops therewith
It is low and rotate backward 90 degree of resets；The piston 44 on top moves down so that second row stomata 4251 and the second air inlet 425 connect
Logical, to be discharged extra gas, the piston 44 of lower part is in moving process by the gas extrusion in the first air cavity 421 from first
Gas vent 4241 is discharged.
Bullet is fixed in 42 inner tip of cylinder body with reference to Fig. 5 and Fig. 6 in order to accelerate the rotation of claw 41 to move down reset
Spring 45, spring 45 can have multiple circumferentially distributed along piston rod 43, and spring 45 can also have one and be set in outside piston rod 43
Side.Compressed spring 45 stores elastic potential energy, when the piston 44 when top moves down, spring when the piston 44 on top moves up
45 release elastic potential energys push piston 44 to accelerate.
The rotation of certain angle is carried out when moving up due to the piston 44 on top, piston 44 is abutted with spring 45
When, piston 44 may will drive spring 45 and twist.It is close in spring 45 in order to reduce damage of this torsion to spring 45
One end of upper piston 44 is fixed with anti-torsion component 46.Anti- torsion component 46 includes the pedestal 462 being fixedly connected with spring 45 and turns
The dynamic turntable 461 being connected on pedestal 462, turntable 461 can be rotatablely connected with pedestal 462 by bearing.The piston 44 on top
It is preferentially abutted with turntable 461 when moving up, when piston 44 rotates, piston 44 drives turntable 461 to rotate, and pedestal 462 can be with
Do not turn, the only compressive deformation under pressure of such spring 45 reduces the possibility of torsion.
The special-shaped molding machine application method of the acrylic board is as follows:
The prefabricated acrylic board adaptable with 31 profile of support plate of annular is placed into support plate 31, adjusting movement makes
Obtain prefabricated acrylic board and 31 coaxial placement of support plate.
Then be blown into high pressure gas to the second air inlet 425 so that claw 41 spin down it is mobile and by acrylic board
Edge is pressed abd fixed in support plate 31, is heated and softened to acrylic board using external heating tool, and softening temperature can be with
It is 110 DEG C -130 DEG C, preferably 120 DEG C.
Then starting vacuum pump 51 vacuumizes, and vacuum degree is -0.3~-0.5MPa, and the acrylic board after softening is external big
Bed die 3 is bonded under gas pressure, as shown in Figure 7.After acrylic board is cooling, stop blowing to the second air inlet 425, and to the
One air inlet 424 is blown, so that the upward moving in rotation of claw 41 is disengaged from acrylic board edge, removes molding special-shaped acrylic
Plate 1.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
