射芯机是采用覆膜砂制芯，适用于热芯盒。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 core shooting machine is made of coated sand core, which is suitable for hot 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 the foundry industry. The core made by the core shooter is precise in size and smooth in surface. 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.
