在垂直分型无箱挤压造型线上,每型12件,生产带盘的轴类铸件,其材质HT200,垂0.6 kg。应用均衡凝固理论,采用等流率设计浇注系统,在内浇道厚度应保证液态传输通道畅通的条件下,取内浇道厚度3 mm,设置排气槽,加强型腔排气,经生产验证,成功完成了该件批量生产的工艺设计。 In the vertical sub-box-free extrusion molding line, each type of 12, the production of the reel shaft casting, the material HT200, hanging 0.6 kg. Applying the theory of equilibrium solidification and designing the pouring system with constant flow rate, the inner runner should be of 3 mm in thickness and the exhaust groove should be set up to enhance the exhaust of the cavity under the condition of the thickness of the inner runner should be ensured that the liquid transport channel is smooth. , Successfully completed the piece of mass production process design.
