上海各厂在大型鑄件上采用混合造型上海地区从大跃进以来,各厂到常州学习泥型铸造后,都广泛加以采用。同时还进一步加以发展,把泥型鑄造同其他造型方法如湿、型、干型、水玻璃砂型以及泥芯等混合起来应用。这样,根据各种型的特点,分别应用于一个铸型的不同的部位,就充分发揮了各种型的优点,而泥型鑄造的应用范围也就更加扩大。上海五力鑄造厂应用于鑄造重6吨的18尺車床床身和重1.5吨的車头,效率比原来提高一倍。上海盈泰鑄造厂用混合 Shanghai factory adopts hybrid modeling on large-scale castings. Since the Great Leap Forward in Shanghai, each factory has been widely adopted after learning mud-casting in Changzhou. At the same time, it has further developed and applied mud casting to other modeling methods such as wet, dry, dry glass, and mud cores. In this way, according to the characteristics of various types, respectively applied to different parts of a casting mold, the advantages of various types are fully exerted, and the application range of the mud casting is even more expanded. Shanghai Wuli Foundry Co., Ltd. is used to cast an 18-foot lathe bed with a weight of 6 tons and a weight of 1.5 tons. The efficiency is double that of the original. Shanghai Yingtai Foundry Mixing
