射芯機(jī)在疊型鑄造中的應(yīng)用

Application of core ejection machine in superposition casting

射芯機(jī)在疊型鑄造中的應(yīng)用,使用射芯機(jī)進(jìn)行芯型制作和芯型成形，合模時垂直疊放芯型，構(gòu)成疊型澆注系統(tǒng)。成形強(qiáng)度高，流動性好，能夠制造形狀復(fù)雜的砂芯，砂芯表面質(zhì)量好，其潰散性好，鑄件容易清理。

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.

射芯機(jī)是壓縮空氣驟然膨脹把芯砂射入芯盒的機(jī)器。射壓式造型機(jī)是利用壓縮空氣將型砂均勻地射入砂箱預(yù)緊實(shí)，然后再施加壓力進(jìn)行壓實(shí)。射芯機(jī)常用的有垂直分型無箱射壓射芯機(jī)和水平分型脫箱射芯機(jī)。

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.

使用射芯機(jī)進(jìn)行芯型制作和芯型成形，生產(chǎn)效率高，起模容易，砂型的尺寸精度高。由芯型疊加組成疊型澆注系統(tǒng)，在澆注時承壓力大，填充力強(qiáng)，產(chǎn)量及成品率高，在保證質(zhì)量的同時生產(chǎn)成本也有所下降，能夠承擔(dān)高精度小型鑄件的大批量生產(chǎn)。

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.
