我厂熔模精密铸造的直浇口浇注系统,是采用空心铸铝浇口捧,外面沾制蜡料制成的。以前是用手工操作,效率低,劳动强度大,沾蜡不均匀。一九七○年十二月我厂蜡型班工人自力更生,自己设计、制成一台浇口棒沾蜡机(图1)。该设备结构简单,操作方便,只需人工挂、摘浇口棒。设备启动后浇口棒自动升降、停留沾蜡,比原手工沾蜡料提高工效五倍左右,沾制蜡棒的质量也较好。现简介如下。供参考。 I plant casting precision casting straight sprue pouring system, is the use of hollow cast aluminum gate holding, outside the system made of wax. Used to be manual, inefficient, labor-intensive, non-uniform dip wax. In July 1970, our factory wax-type workers self-reliance, their own design, made of a gate stick stick wax machine (Figure 1). The device has the advantages of simple structure, convenient operation, just hanging by hand and picking the sprue stick. After the device is started, the gate rod automatically moves up and down, leaving the wax on, which enhances work efficiency by about five times than that of the original hand-stick wax. The quality of dip stick is also better. Now the introduction is as follows. for reference.
