[0047] Secondly, the working principles of the top mold oil supply assembly and the top mold air supply system are similar to the mold oil supply and air supply, which will not be repeated here.

[0048] Preferably, the molding machine feeding trolley 1 of this embodiment can reciprocate along the length direction of the mold and the top mold;

[0049] The oil supply system includes:

[0050] Fuel tank 2; and

[0051] A mold oil supply assembly and a top mold oil supply assembly connected to the oil tank 2;

[0052] The mold oil supply assembly has a mold oil supply pipeline 401 connected to the oil tank 2, the mold oil supply pipeline 401 extends downward to face the mold, and a mold oil nozzle 402 is installed at the end of the mold oil supply pipeline 401;

[0054] The oil tank 2 of this embodiment is a rectangular box body formed by welding steel plates;

[0055] The size of the oil tank 2 is 500mm*250mm*300mm.

[0056] First, this embodiment defines the composition of the oil supply system in detail, which includes a rectangular oil tank 2 made of waste steel plates, which is easy to obtain and saves costs.
