The invention discloses an
injection moulding water conservancy equipment achieving negative pressure suction and tiling pressurization. The
injection moulding water conservancy equipment structurallycomprises a formwork, a
fixed frame, a lower steel plate, a bearing plate, a negative pressure pump, a
welding column, an air guide
pipe, a three-fork pressurizing structure, an interlayer plate, anair suction opening, an adhering net, an inner formwork, a clamping mechanism, an air guide column and a one-way valve. According to the
injection moulding water conservancy equipment, after injectionis carried out on the equipment, pressure is increased, a connecting
handle is pressed through a compacting column, a first compacting plate and a second compacting plate are expanded downwards to beattached to the top of a
cement layer till the first compacting plate and the second compacting plate are kept horizontal, and the first compacting plate and the second clamping plate are clamped byan inner roller and cannot be bent towards the inner side through the resisting function of a clenching sheet, a surrounding spring and a pressing block;
cement is pressed through pressure exerted again, and the compaction degree of the
cement is increased; after pressing is carried out, the negative pressure pump is started, air in the interlayer plate is sucked away, air attached to a pluralityof air suction opening ends on the adhering net is sucked, the air suction opening is communicated with the cement end, bubbles and air in the cement are sucked away, and clearances between the cementbecome small.
