在无产阶级文化大革命和批林整风运动的推动下,我厂广大革命职工,遵照伟大领袖毛主席关于“抓革命,促生产,促工作,促战备”的伟大教导,以路线斗争为纲,在学习兄弟单位先进经验的基础上,设计和制造了一台两工位粘土砂射芯机,并于去年投入试生产,现将有关情况介绍如下。一、概况两工位粘土砂射芯机,用于制造1～5~#的JO_2型电机机座泥芯(见图1)。机座泥芯的特点是高度大,如5~#机座泥芯盒的有效高度 Driven by the Great Proletarian Cultural Revolution and the campaign of rectifying forests and rectifying the wind, the revolutionary workers and staff of our factory follow the great teachings of Chairman Mao on the principle of “grasping the revolution, promoting production, promoting work and promoting war preparedness.” Taking the struggle on the line as the key link, On the basis of learning advanced experience from brother units, we designed and manufactured a two-station clay sand core shooting machine and put it into trial production last year. The relevant information is as follows. First, an overview of the two positions of clay sand core shooting machine, used to make 1 ~ 5 ~ # JO_2 motor frame mud core (see Figure 1). Mud base is characterized by a large height, such as 5 ~ # base mud box effective height
