我厂生产900mm～1400mm四种规格吊扇。以1400mm吊扇转子为例(如图1所示),过去我们把浇道设在压铸模底模上,而且底模不是固定在压铸机工作台上。这样在转子脱模过程中较困难,经常出现铝粘在底模上。另外工序多、劳动强度大,生产效率低。为此我们对模具进行改进,改进后的模 I plant 900mm ~ 1400mm four kinds of ceiling fans. Taking the 1400mm ceiling fan rotor as an example (as shown in Figure 1), in the past we set the runner on the die of the die-casting mold, and the bottom mold was not fixed on the die-casting machine table. This is more difficult in the process of demolding the rotor, aluminum often appears on the bottom die. In addition to more processes, labor-intensive, low productivity. To this end we improve the mold, improved mold
