我厂生产的B01——灌浆泵,其泵体是关键件。该零件外形长460毫米、宽230毫米、高130毫米,内腔由11个交叉孔组成,重45公斤,铸造牌号ZG45,是一个典型的多孔类铸件。采用熔模铸造后,成品率可达95％以上。 一、蜡型的制作 泵体铸件的压型设计与制造,由于内腔复杂和孔之间的交叉,会造成一些芯销(铁芯)无法抽出,如用尿素型芯、陶瓷型芯成本既高、又不利于工人操作。针对这一问
I plant production B01 - grouting pump, the pump is the key components. The part is 460 mm long, 230 mm wide and 130 mm high. The cavity consists of 11 intersecting holes and weighs 45 kg. The casting designation ZG45 is a typical porous cast. After using investment casting, the yield can reach more than 95%. First, the wax-type production Pump body casting pressure design and manufacturing, due to the complexity of the cavity and the hole between the cross, it will cause some of the core pin (core) can not be withdrawn, as with urea core, ceramic core cost High, but not conducive to the operation of workers. For this question
