殼芯機(jī)制殼芯是應(yīng)注意：

The core of shell core mechanism should be paid attention to:

1） 加砂前，殼芯盒內(nèi)應(yīng)噴涂分型劑。

1) spray molding agent should be sprayed in the core box before adding sand.

2） 加砂時(shí)，應(yīng)先往砂斗內(nèi)加少量砂，一般砂量深度距射砂口多少應(yīng)按工藝規(guī)定的要求，加砂過(guò)多則殼芯機(jī)易產(chǎn)生縮脖，過(guò)少易使殼芯機(jī)吹不成。

2) when the sand is added, a small amount of sand should be added to the sand bucket first.

3） 應(yīng)根據(jù)殼芯的大小赫然結(jié)構(gòu)嚴(yán)格掌握每個(gè)殼芯制造的吹砂、結(jié)殼、排出余砂、硬化、頂出殼芯等環(huán)節(jié)的時(shí)間。

3) according to the size and size of the shell core, we must strictly control the time of blowing, crusting, discharging sand, hardening, ejecting core and so on.
