一、前言液态模锻又称挤压铸造。它是介于铸造和锻造之间的一种新工艺。液态模锻的实质,是把一定量的液态金属直接浇入金属模具内,通过凸模(冲头)下降使之形成封闭的型腔并施加以压力,迫使液态金属充满模具各个部位而形成所需的工件。在整个凝固过程中,对工件的整个表面保持压力,以便压实工件内部在金 First, the foreword Liquid die forging, also known as squeeze casting. It is a new process between casting and forging. The essence of liquid die forging is to pour a certain amount of liquid metal directly into the metal mold by forming a closed cavity by lowering the punch (punch) and applying pressure to force the liquid metal to fill all parts of the mold to form a Required parts. In the whole solidification process, the entire surface of the workpiece to maintain pressure in order to compact the workpiece inside the gold
