我厂“机油泵座”铸件,过去用砂型铸造,劳动强度大,生产率低。改压力铸造后,生产率大大提高,铸件外形光洁美观,尺寸精确度高。现将“机油泵座”压铸模设计情况介绍如下: “机油泵座”铸件呈蜗壳形四面体(图1),其轮廓尺寸为165×133×64(毫米)。壁厚基本均匀,平均为3.5毫米。加强筋较 Our factory “oil pump seat” castings, the past casting with sand, labor-intensive, low productivity. After the pressure casting, the productivity is greatly improved, the appearance of the casting is smooth and beautiful, and the dimension accuracy is high. Now “oil pump seat” die-casting mold design situation is as follows: “Oil pump seat” was volute-shaped tetrahedron casting (Figure 1), the outline size of 165 × 133 × 64 (mm). Wall thickness is basically uniform, with an average of 3.5 mm. Stiffener more
