Plastic mold, a combination of plastic molds for press molding, extrusion, injection, blow molding and low foam molding, is usually classified according to the molding material, processing technology, pouring system when the plastic mold is classified. 1, according to the pouring system type of different plastic molds can be divided into three categories: (1) large water mouth mold: runner and gate in the die line, and the product in the opening mold together with the mold, the design is the simplest, easy to process, low cost, so more people use large water port system operation. (2) fine water mouth mold: runner and gate is not on the die line, generally directly on the product, so to design a more group of water mouth die line, design is more complex, processing is more difficult, generally depending on product requirements and choose fine water port system. (3) Hot runner mold: this type of mold structure and fine water port is generally the same, the biggest difference is that the runner is in one or more heated hot runner plate and hot mouth, no cold material release, runner and gate directly on the product, so the runner does not need to release, this system is also called anoquiid system, can save raw materials, more expensive raw materials, Product requirements are high, design and processing difficulties, mold costs are higher. 2, according to the plastic mold molding material can be divided into: thermoset plastic mold and thermoplastic mold 3, according to the plastic mold molding process can be divided into: plastic injection molding mold; plastic molding mold; plastic extruded molding mold; plastic blow molding mold; plastic blister molding mold; high foam polystyrene molding mold; high foam polystyrene molding mold
