通訊井模具采用組裝的方式構(gòu)成，具有良好的組裝、拆模過程。該模具分為內(nèi)膜和外模兩部分，使用簡單方便。因為該模具為質(zhì)鋼的，這種材質(zhì)容易生銹，為了防止生銹在不用時涂抹潤滑油。隔絕空氣防止和氧氣發(fā)生氧化，增加脫模的平滑性，同時也可以增加模具的使用壽命。The communication well mold is composed of assembly, which has a good process of assembly and removal. The mold is divided into inner mold and outer mold, which is simple and convenient to use. Because the die is made of steel, this material is easy to rust. In order to prevent rust, apply lubricating oil when not in use. Isolate air and oxygen to prevent oxidation, increase the smoothness of demoulding, and increase the service life of the die.
