砂箱的定位一般,砂型铸造的铸型都采用两只钢或砂制的两头锥定位销。虽然钢制定位销浇注后可以回用,但总有一部分损耗掉,再加上用量大,给生产带来一定的不便。为了解决这个问题,我们设计了一种浇注时不用两头锥定位销的定位方法:在上型板和下型板的相应位置安装如图1所示的定位块各两只。下箱造型后则在下型上留有同定位块一样形状的凹窝;上箱造型时,首先在上型板两定位块上套一定位销套(图2)然后再紧砂
The location of the sandbox is generally, sand casting molds are made of two steel or sand cone head positioning pin. Although the steel positioning pin can be reused after casting, but there is always some loss, coupled with the large amount of usage, to bring some inconvenience to the production. In order to solve this problem, we have designed a method of positioning without a two-headed cone positioning pin when casting: two positioning blocks, each of which is shown in FIG. 1, are installed at corresponding positions of the upper plate and the lower plate. After the next box shape is left in the next type with the positioning of the same shape of the dimples; box modeling, the first two sets of blocks in the upper set of a positioning pin sets (Figure 2) and then tight sand
