Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in fig. 1-6, the utility model discloses a stopper stick support for reversing molding machine, include the linking arm 17 of being connected with graphite stopper stick 15, still include cylinder head 5, piston 10, piston rod 6 lower extreme and piston 10 installation, piston rod 6 upper end is passed from cylinder head 5 with linking arm 17 fixed connection, cylinder head 4 fixed mounting is on cylinder 9, the lateral wall of cylinder head 4 has the cavity through-hole, piston rod 6 passes from the cavity through-hole, the lateral wall of the cavity through-hole of cylinder head 6 is equipped with guide way 16, this guide way 16 includes straightway 161 and helical segment 162, helical segment 162 and straightway 161 smooth linking, be equipped with the swivel pin 7 that is arranged in guide way 16 on the piston rod 6. The straight line segment 161 and the spiral segment 162 of the guide groove 16 are utilized, and the spiral segment is located at an upper position so that the entire guide groove has a certain rotation lead angle. Thereby the cylinder is at the in-process that drives the piston rod and rises, when rotatory round pin slides to the spiral section from the straightway, can receive a directional effort to make rotatory round pin under the effect of guide way, use the piston rod to take place to rotate as the rotation center axle, further make the linking arm also rotate, thereby realized the rotation of stopper stick, changed the original central axis position of stopper stick.

The absolute value of the difference between the angle between the axis of the connecting arm 3 and the horizontal when the rotating pin 7 is located in the straight line segment 161 of the guide groove 16 and the angle between the axis of the connecting arm 3 and the horizontal when the rotating pin 7 is located in the inclined segment 162 of the guide groove 16 is greater than 6 degrees. When the rotating pin is positioned at a certain position of the straight line section, the closing state of the blocking rod is obtained, and when the rotating pin is positioned at a certain position of the inclined section, the complete lifting state of the blocking rod is obtained.

In addition, the upper end of the piston rod 6 penetrates through the connecting arm 17 and then is locked and installed with the connecting arm 3 through the round nut 1 and the gasket 2. Through the fixed sleeve, the piston rod can ascend and descend more stably.

The connecting arm 17 comprises a blocking support rear seat 3 and a blocking support swing arm 14, a mounting hole is formed after the blocking support rear seat 3 and the blocking support swing arm 14 are assembled, and the blocking rod 15 is inserted into the mounting hole and is locked and fixed through a nut. The blocking bracket swing arm 14 is fixedly installed with the blocking bracket rear seat 3 in a locking mode through a screw and nut assembly 13.

The blocking support rear seat 3 is provided with a special-shaped fixing gasket 11, a mounting bolt on the special-shaped fixing gasket 11 is locked into the blocking support rear seat and locked, and the blocking support rear seat 3 is pressed by the special-shaped fixing gasket.
