DK28 Diesel Engine Parts Introduction Top Block in Mould

For marine diesel engine parts, the top block in the mold is used to support the shape, and the entire mold plate is not solid, but consists of mold bottom frame, spacer block, top block, etc. The top block is part of the mold ejection system. Generally used in injection molds.

Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to injecting the melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained.

Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to their molding characteristics; they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. , Among them, the hot pressing mold can be divided into three types: overflow type, semi-overflow type and non-overflow type according to the overflow method. The injection mold can be divided into cold runner mold and hot runner mold according to the gating system. It can be divided into two types: mobile and fixed.
