        首先，鑄件的外形應(yīng)該便于使鑄件無阻礙地從金屬型中取出。如果零件在金屬型中靠近分型面的尺寸小，靠型腔內(nèi)部的尺寸大，這樣的設(shè)計會阻礙鑄件的順利取出。但如果沿鑄件從金屬型中取出的方向有斜度，那么取出鑄件的過程將簡化很多。……Detailed

        1.真空吸氣澆注：將型殼放在真空澆注箱中，通過型殼中的微小孔隙吸走型腔中的氣體，使液態(tài)金屬能更好地充填型腔，復(fù)制型腔的形狀，提高鑄件精度防止氣孔、澆不足的缺陷。2.硅溶膠精密鑄造的壓力下結(jié)晶：將型殼放在壓力罐內(nèi)進行澆注，在結(jié)束后，立即封閉壓力罐，向罐內(nèi)通入高壓空氣或惰性氣體，使鑄件在壓力下凝固，以增大鑄件的致密度。
