style="text-indent:25px">覆膜砂模具的生產(chǎn)工藝和設(shè)計問題。鑄造模具模擬鑄造充型過程、凝固過程，預(yù)測鑄件各處溫度變化及鑄型溫度的變化、預(yù)測鑄件澆不足、卷氣、縮孔、縮松等缺點，覆模砂模具在后處理中以圖形顯示，使用這套軟件，無疑會給鑄造企業(yè)帶來較大的經(jīng)濟效益。覆膜砂模具的具體工藝是指為了獲得零件的結(jié)構(gòu)形狀，預(yù)先用其他容易成型的材料做成零件的結(jié)構(gòu)形狀，然后再在砂型中放入模具，于是覆模砂模具砂型中就形成了一個和零件結(jié)構(gòu)尺寸一樣的空腔，再在該空腔中澆注流動性液體，該液體冷卻凝固之后就能形成物件了。

3、鑄件內(nèi)部縮松覆膜砂中的樹脂在高溫下燃燒產(chǎn)生熱量，減緩了鐵水的凝固速度，導(dǎo)致縮松。采用激冷類覆膜砂；在殼型芯內(nèi)放置內(nèi)冷鐵。 4、鑄件表面不良酚醛樹脂在高溫下生成的光亮碳漂浮在鐵液表面，凝固時鑄件表面產(chǎn)生皺皮。加入2%左右氧化鐵粉，采用導(dǎo)熱率高的原砂；殼芯表面刷涂料；覆膜砂中添加特殊輔料。 5、型(芯)表面疏松——射芯壓力過高或過低，模具排氣不暢；模具由于分盒面間隙大而跑砂；覆膜砂流動性差或透氣性差。選用合理射砂壓力，改善排氣系統(tǒng)，防止憋氣；采用變形小的材料作芯盒；選用流動性和透氣性好的覆膜砂 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
