覆膜砂热芯盒射芯机造型的优点：

The advantages of the molding of the core shooting machine for the coated sand hot core box:

1 成本低

1 low cost

(1)一次性投资少

(1) less one-time investment

覆膜砂热芯盒射芯机制型(芯)一次性投人为热芯盒射芯机和模具。射芯机每台价格在1.6-3.5万元不等，每套模具在0．6～1．0万元。

The hot core box core mechanism (core) of the coated sand core throws the core and the mould of the hot core box at one time. The price of the core shooter is 1.6-3.5 yuan, and each mould is between 0.6 and 10 thousand yuan.

(2)生产成本低

(2) low production cost

覆膜砂热芯盒射芯机制壳材料只有覆膜砂和脱模剂，覆膜砂工艺制壳仅有一台射芯机耗电。

The core shell mechanism of coated sand core box is covered with coated sand and mold release agent.

2 制壳环节少、效率高

The 2 tache of the shell is less and the efficiency is high

(1)制壳环节少、生产周期短

(1) few tache and short production cycle

覆膜砂热芯盒射芯机利用气压将覆膜砂吹入金属型型腔中，采用电加热棒加热金属型对覆膜砂进行加热硬化，从而形成型壳，即可合箱浇注，加热过程仅需要1-3min（视工件来定），周期短，环节少。

The coated sand hot core box shooter blows the coated sand into the metal type cavity by using the air pressure. The electric heating rod is used to heat and harden the coated sand, thus forming the shell, which can be poured in the box. The heating process only needs 1-3min (depending on the workpiece), the cycle is short and the link is few.

采用覆膜砂热芯盒工艺使用双工位射芯机每台每班产量为150模，每模12个铸件，每班产量为1800个铸件，人均产量是人工造型的6倍。

The production of hot core box with film covering sand is 150 die per class and 12 castings per module with 1800 castings per class, and the per capita output is 6 times that of artificial molding.
