射芯机在叠型铸造中的应用

Application of core ejection machine in superposition casting

射芯机在叠型铸造中的应用,使用射芯机进行芯型制作和芯型成形，合模时垂直叠放芯型，构成叠型浇注系统。成形强度高，流动性好，能够制造形状复杂的砂芯，砂芯表面质量好，其溃散性好，铸件容易清理。

The application of core shooting machine in stacking casting uses core shooting machine for core making and core forming. When the mold is closed, the vertical stacking core is used to form the stacking gating system. With high forming strength and good fluidity, it can make sand cores with complicated shape. The surface quality of sand core is good, its collapsibility is good, and castings are easy to clean.

射芯机是压缩空气骤然膨胀把芯砂射入芯盒的机器。射压式造型机是利用压缩空气将型砂均匀地射入砂箱预紧实，然后再施加压力进行压实。射芯机常用的有垂直分型无箱射压射芯机和水平分型脱箱射芯机。

The core shooter is a machine that suddenly expands the compressed air and shoots the core sand into the core box. The injection molding machine is designed to compress the molding sand evenly into the sand box before compacting with compressed air, and then compress it with pressure. The core shooting machine commonly has vertical parting and no box shooting and core shooting machine and horizontal parting and debox core shooting machine.

使用射芯机进行芯型制作和芯型成形，生产效率高，起模容易，砂型的尺寸精度高。由芯型叠加组成叠型浇注系统，在浇注时承压力大，填充力强，产量及成品率高，在保证质量的同时生产成本也有所下降，能够承担高精度小型铸件的大批量生产。

Core shooting and core molding are made by using the core shooting machine. The production efficiency is high, the mold is easy to be taken, and the size accuracy of the sand mold is high. The pouring system composed of core type superposition has large bearing pressure, strong filling force, high yield and high yield. At the same time, the production cost is reduced and the high precision small castings can be produced in mass production.
