覆膜砂射芯机的应用

发布时间:2020-01-11
覆膜砂射芯机是采用覆膜砂制芯,适用于热芯盒和冷芯盒两种。射芯机的特点是应用两根导柱,开合模垂直分型,同时安装两副不同的模具,中间固定架可以双面安装定模,左右开合模(相当于双模架)。射芯机广泛应用于铸造行业中,用射芯机制造的型芯尺寸精确,表面光洁。射芯机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,砂芯在芯盒内预热很快硬化到一定厚度(约为5~10 mm) 将之取出,形成表面光滑、尺寸精确的优质砂芯成品。
The coated sand core machine is made of coated sand core, which is suitable for two kinds of hot box and cold box. The core machine is characterized by the application of two guide columns, the opening and closing die vertical typing, and the simultaneous installation of two different moulds. The middle fixer can be fixed on both sides and the die is left and right (equivalent to a double die frame). The core shooting machine is widely used in foundry industry, and the core size produced by the core shooter is precise and smooth. The working principle of the core ejection machine is that the core sand mixture with liquid or solid thermosetting resin as the binder is injected into the core box after heating. The preheating of the core in the core box is quickly hardened to a certain thickness (about 5~10 mm) and will be taken out to form a smooth and accurate quality sand core product.
射芯机近年来应用比较广泛,由于使用射芯机造型可以省去高额的造型工工资。因为是多箱叠放浇注还能减少浇冒口的浪费,浇注后的覆膜砂溃散性很好,利于清砂。射芯机生产效率高,砂型尺寸精确,可适当减少加工量;操作简便,铸件成品率高。
The core shooting machine has been widely applied in recent years, because the use of core shooting machine modeling can save high stylist wages. Because it is a multi box stacked pouring riser can reduce the waste of coated sand casting after collapsibility is good for cleaning. The core shooter has high production efficiency, precise sand mold size, and can reduce the processing volume appropriately. It is easy to operate and has high yield of castings.
