目前水暖器材行业主要还是采用砂型铸造,采用硬模只限于几种简单的另件,还不普遍.因此,有必要对在这一行业内采用硬模或砂型铸造的得失加以分析比较. (一)采用硬模铸造的优点: (1)硬模铸型使用寿命长,一付硬模铸型用来浇易熔合金铸件,可浇几十万个,就是浇铸铁件也可以浇1,500-5,000个.而砂型只能浇铸一次.砂型铸造需要耗用的大量的造型工时,采用硬模就可以节约很多. (2)操作容易掌握,硬模铸造只要在制造铸型时集中技术力量把铸型造好,以后在浇注过程中的操
At present, the plumbing equipment industry mainly adopts sand casting. The use of hard molds is limited to a few simple parts. It is not yet common. Therefore, it is necessary to analyze and compare the gains and losses of hard dies or sand castings in this industry. ) Advantages of hard die casting: (1) Hard die castings have a long service life, a hard die casting type is used to cast fusible alloy castings, can be poured in hundreds of thousands, that is, cast iron pieces can also be poured 1,500-5,000 The sand type can only be cast once. The sand casting requires a lot of sculpting man-hours. Using a hard die can save a lot. (2) The operation is easy to master. The die casting only needs to focus on the technical force when casting the mold. Made well, later in the pouring process
