4.2/4.8/6.0m Mould of AAC Block AAC Production Line Concrete Block
size:4.2m/4.8m(5m)/6m X1.2m X0.6m
The mould (see attached drawing) is a special device for block
pouring. The mortar delivered from the pouring mixer is poured into
the inner chamber of the mould. Then, after fermentation and
curing, with the mould frame stripped off, these materials become
blocks waiting to be cut.
2. Technical specifications (4.2m)
a) Maximum overall dimensions:
4630 mm (length) × 1712 mm (width) × 1015.5 mm (height)
b) Dimensions of poured blocks (net size after cutting)
4200 mm (length) × 600 mm (width) × 1200 mm (height)
c) Mass: 1955.18 kg (including the side plate weighing 512 kg)
d) Quality of sealing strips: GCB6-89 foam rubber
The mould is composed of four units: mould frame, side plate
(bottom plate), clamping arm and wheels
a) Mould frame:
The mould frame is a framework made of steel sections and plates.
It features good rigidity and small weight.
There are turnover shafts on either end and wheels at the bottom.
There are also sealing strips intended to prevent leakage at the
time of pouring. The mould has a reasonable structure and can turn
b) Side plate (bottom plate):
The side plate is welded from steel sections and plates. Very good
in rigidity, it will not become deformed easily after it is put
into the autoclave.
c) Clamping arm:
The clamping arm is composed of the pinch roller, the arm and the
rotating shaft. It is driven by the manual control on the turnover
The mould can work only when the mould frame, the side plate
(bottom plate) and the clamping arm are put together into an
integral body. Besides, the mould cannot work without the turnover
a) Mould frame:
The mould frame is the main body of the mould. The side plate is
mounted on the mould frame and clamped by the clamping arm. Then
when the mould is turned over ninety degrees, it will be possible
to do pouring. After the pouring is finished, the mould will be
lifted in the air by the turnover hoisting device, turned over
ninety degrees so that the block stands upright, and carried to the
cutting table. Then the clamping arm will be loosened, and the
mould frame stripped off. After that, the block will be cut.To
start the next cycle, the mould frame will have the side plate
mounted on it, be tightened by the clamping arm and turned over
ninety degrees. Now it has become a mould capable of receiving the
pouring once again.
b) Side plate:
The side plate is a wall plate on the opening side of the mould
frame. The mould will be turned over ninety degrees after it is
tightened by the clamping arm and sealed tightly with sealing
strips. On the cutting table, when the mould is stripped off, the
side plate will become the bottom plate of the block.
c) Clamping arm:
The manual control on the turnover hoisting device can drive the
clamping arm to turn ninety degrees, thus making the clamping arm
tightened or loosened.
The mould is already assembled when it is delivered ex works. The
only thing to do on site is to put sealing strips on the opening
side of the mould frame. The adhesive for mounting the sealing
strips is chloroprene glue (303 super glue) or
phenolic-butyronitrile glue (Tiemao 705 glue, or JX-5).
6.Inspection and adjustment
i. After the mould frame and the side plate are put together, the
clamping arm should be able to turn freely without jamming.
ii. After the side plate is clamped tight and the mould is turned
over ninety degrees, there should be no leakage from the sealing
i. If there is too big a gap between the clamping arm and the side
plate or serious jamming occurs when the clamping arm turns, adjust
the distance between the clamping arm and the mould frame.
ii. If there is leakage from the sealing strips, adjust the pinch
roller on the clamping arm.
a) Daily care
i. Remove all residual mortar and dirt.
ii. Coat the inner chamber with lubricant after the mould frame and
the side plate are put together.
iii. Lubricate the wheels periodically.
Replace damaged sealing strips in good time.
Do not allow anybody to stand in the work area in the process of
pouring and stripping off the mould.
