Lifting and compacting mechanism of horizontal parting slip flask shoot-squeeze molding machine

Abstract

The invention discloses a lifting and compacting mechanism of a horizontal parting slip flask shoot-squeeze molding machine. The lifting and compacting mechanism comprises a bottom girder, a master cylinder, a master cylinder base, a flask lifting piston cover and four lifting guide bars. The master cylinder base is fixedly arranged on the bottom girder, the master cylinder is mounted on the master cylinder base, the flask lifting piston cover is fixedly arranged on the end face of a master cylinder piston rod, a guiding sleeve and two copper sleeves are arranged corresponding to each lifting guide bars, the four guiding sleeves are correspondingly distributed at four vertex angles of the master cylinder base, the four lifting guide bars are respectively mounted in corresponding guiding sleeves, and the top ends of the lifting guide bars are inserted to the lower end of the flask lifting piston cover and are fixed with the lower end face of the flask lifting piston cover. According to the lifting and compacting mechanism of the horizontal parting slip flask shoot-squeeze molding machine, the rigidity and strength of the whole mechanism are greatly enhanced, so that a movement process for the whole mechanism is smoother, and the possibility of tilting and deforming is reduced; and the lifting and compacting mechanism is easy to manufacture and fabricate.

Description

Technical field [0001] The invention relates to the field of lifting and compacting sand molds on a molding machine, in particular to a lifting and compacting mechanism of a horizontal parting box-off injection molding machine. Background technique [0002] The lifting and compaction mechanism is the key mechanism for closing, compacting and demolding in the horizontal parting and ejection molding machine. The existing lifting and compacting mechanism of the horizontal parting box ejection molding machine, such as figure 1 , figure 2 As shown, it mainly includes the bottom beam 1, the main oil cylinder 3, the main oil cylinder base 2, the lifting box piston cover 7, the lifting guide rod 6, the guide sleeve 4 and the copper sleeve 5 and other components. The main oil cylinder base 2 is fixed on the bottom beam 1, the main oil cylinder 3 is installed on the main oil cylinder base 2, the box lifting piston cover 7 is fixed on the end surface of the piston rod of the main oil cylin...
