热芯盒射芯机的工作原理

发布时间:2020-01-11
射芯机整棵铸件组树采用机械振动的办法,使型壳得以从铸件上剥落,冲击频率越高,冲击功越大,则清理的效果就好。工作原理是将以液态或固态热固性树脂为粘结剂的芯砂混合料射入加热后的芯盒内,砂芯在热的芯热芯盒。如选配气体发生系统,则本机可满足冷芯盒制芯的要求。热芯盒射芯机工作过程是填砂与紧实同时完成。这种清壳方法设备简单,生产率高,但存在噪声和粉尘污染。对于铸件上小孔、盲孔、窄槽等处的型壳不易清除。Mechanical vibration is adopted in the whole castings tree of the core ejection machine, so that the shell can be stripped from the castings. The higher the impact frequency and the greater the impact work, the effect of the cleaning is good. The working principle is that the core sand mixture with liquid or solid thermosetting resin as the binder is injected into the heated core box, and the sand core is in the hot core hot box. If the gas generation system is selected, the machine can meet the requirements of cold box core making. The working process of the hot box core shooter is completed by sand filling and compaction. The shell cleaning method is simple in equipment and high in productivity, but there are noise and dust pollution. It is not easy to remove the shell on the small holes, blind holes and narrow grooves on the casting.
