鑄件加工面一旦產(chǎn)生疏松、縮松則成為廢品。疏松首先可能是由于結(jié)構(gòu)不合理而引起的。疏松、縮松與縮孔一樣產(chǎn)生在壁厚較大的部位上,甚至產(chǎn)生在凹角部位,因?yàn)樵撎幨峭ㄟ^相應(yīng)鑄型凸臺(tái)部份或泥芯進(jìn)行散熱,故該處散熱差,金屬凝固比較緩慢。對(duì)具有30或60“或90,張角的Y型試塊的對(duì)比試驗(yàn)表明、凹角處外縮孔,隨張角增大而減小與此同時(shí)縮孔減少,而使疏松增加。設(shè)計(jì)出工藝上合理的結(jié)構(gòu)是獲得致密鑄件的重要條件之一。但對(duì)一個(gè)鑄件;結(jié)構(gòu)設(shè)計(jì)員設(shè)計(jì)時(shí)首先考慮的是使用要求;其次才是工藝上的合理性。
Once the casting surface is loosened and loosened, it becomes a waste product. Looseness may first be caused by an unreasonable structure. Looseness, shrinkage and shrinkage are produced in the part with a large wall thickness, even in the concave corner, because the heat is dissipated through the corresponding casting boss or core, so the heat is poor, metal solidification It is slow. A comparative test of a Y-shaped test piece having a 30 or 60" or 90-angle angle indicates that the shrinkage hole at the concave corner decreases as the opening angle increases, and at the same time, the shrinkage hole decreases, and the looseness increases. A reasonable structure is one of the important conditions for obtaining a dense casting. However, for a casting; the structural designer first considers the use requirements; the second is the process rationality.
