Set up the side forms in 6 both sides of core pulling pipe, 18 are touched on the left side mould 17 and the right that the side forms include bilateral symmetry and set up, and the upper end of side forms is installed and is born one-level vibrating device and second grade vibrating device's supporting rack 9, one-level vibrating device includes fixing base 10, goes up vibration board 11, one-level vibrating motor 12 and vibration transfer plate 13, and fixing base 10 is installed on the frame 1 of both sides, and fixed mounting goes up vibration board 11 on fixing base 10, installs one-level vibrating motor 12 on last vibration board 11, and the lower part of going up vibration board 11 is provided with vibration transfer plate 13, just the vibration height ratio side forms of one-level vibrating device vibration transfer plate 13 sinks 3-5 mm.

The secondary vibration device comprises a vertical vibration motor 14 and a secondary vibration plate 15, and the vibration height of the secondary vibration device is equal to the height of the side die.

The working principle is as follows: adding water into powdery materials such as fly ash and gypsum powder, putting the powdery materials into a stirrer for stirring to obtain mixed materials, driving a driving motor 2, a primary vibrating device and a secondary vibrating device, moving a backing plate 16 to the bottom of an extrusion cavity, and forming a forming cavity by the backing plate 16 and a side die. The mixed material is fed into the extrusion cavity through the feed hopper 4, the pushing block 7 is driven to move through the crank mechanism 8, the mixed material is pushed and extruded and formed in the extrusion cavity, vibration molding is carried out through the primary vibrating device, the raw material is filled in the wallboard forming cavity, the secondary vibrating device continues to vibrate and tamp, a light partition board blank is obtained, and a finished light partition board is obtained after drying and curing.

Has the advantages that: according to the pushing wallboard machine, due to the pushing forming, the pushing forming is performed by a professional aiming at pure powder raw materials, and the problem that a common spiral conveying forming machine can complete the forming only by a thick bone according to the grading requirement formula is solved; meanwhile, double rows of equal-through holes can be arranged on the wall board, so that the hole rate is increased, and the effect of lighter weight is achieved; but also can form very thin plates, and overcomes the defect that the forming condition can be met only by spirally extruding the wallboard with certain thickness; the one-level vibration region is 3-5 mm than the side forms sinks, the height is equal such as the second grade vibration region and side forms, can guarantee to obtain the better wallboard of closely knit nature behind the secondary oscillation, vibrate through the one-level vibration and mould the type, make the raw materials fill up the wallboard shaping chamber, vibrate the ramming through the second grade, thereby can reduce the probability that loose position appears in the wallboard, can improve the closely knit nature and the quality of wallboard, reduce the disqualification rate of wallboard, increase the security that the wallboard used.
