機(jī)械化、自動(dòng)化生產(chǎn)形式機(jī)械化、自動(dòng)化生產(chǎn)的鑄造廠一般需要大量的砂芯，要求制芯設(shè)備生產(chǎn)率高、占地面積小，運(yùn)輸量小，并且容易組織機(jī)械化、自動(dòng)化生產(chǎn)以滿足鑄造生產(chǎn)的需要。因此，可選擇如下兩種硬化工藝的制芯設(shè)備。

In general, a large amount of sand core is needed for mechanization and automation production, which requires high productivity, small area and small transportation, and it is easy to organize mechanization and automation to meet the needs of foundry production. Therefore, two core hardening equipment can be selected.

芯盒內(nèi)加熱硬化制芯設(shè)備芯盒內(nèi)加熱硬化制芯設(shè)備主要有熱芯盒射芯機(jī)、殼芯盒機(jī)及多用途制芯機(jī)。這些制芯設(shè)備采用電或煤氣對(duì)金屬芯盒內(nèi)的砂芯加熱硬化成形。制出的砂芯強(qiáng)度高、表面光潔、尺寸精度高，一般不必采用芯骨，潰散性好。同時(shí)，單臺(tái)設(shè)備結(jié)構(gòu)緊湊，占地面積小，生產(chǎn)率高，運(yùn)輸方便。

In the core box, the heating hardening core making equipment is mainly composed of a hot core box core shooting machine, a shell core box machine and a multi-purpose core making machine. The core making equipment uses electricity or gas to harden the sand core in the metal core box. The sand core has high strength, smooth surface and high dimensional accuracy, and generally does not need to use core bone, so it has good collapsibility. At the same time, the single equipment has compact structure, small footprint, high productivity and convenient transportation.

盡管芯盒內(nèi)加熱硬化制芯設(shè)備能耗較高，但由于具有上述優(yōu)點(diǎn)，而且電和煤氣等能源容易獲得，因而得到許多鑄造廠廣泛使用。

In spite of the high energy consumption of the core heating and hardening equipment, the core box is widely used by many foundries because of its advantages and easy access to electricity and gas.
