(3) manufacturing a counter weight male die matched with the through hole on the outer skin cover plate;
(4) assembling a counterweight female die and a counterweight male die, and adding fillers into a filling opening;
(5) after the filler is solidified and formed, drawing out the counter weight male die, and standing or ventilating until the filler is air-dried;
(6) and (3) manufacturing core blocks matched with the through holes in batches, inserting one or more core blocks into the through holes, and adjusting the weight of the balance weight.
Preferably, a decorative cover plate is fixed on the surface after the step (6) is completed.
Preferably, the cross section of the through hole is in any one or more of a circle, a polygon or an ellipse.
Preferably, the filler in the step (4) is concrete and/or steel.
Preferably, the core block material in the step (6) is concrete and/or steel.
Compared with the prior art, the invention has the advantages and positive effects that:
1. the air drying of the through holes is beneficial to the rapid air drying and curing of the fillers such as the concrete and the like in the filler, and the air drying and curing time of the balance weight is greatly shortened.
2. The increase and decrease of the whole weight of the balance weight can be realized by increasing and decreasing the number of the pellets and different materials, the industrial production line operation can be realized, and the production efficiency is effectively improved.
3. The concrete filling and air drying inside the concrete curing device is good in curing, and the appearance quality can be effectively controlled and improved.
