The invention discloses a plasticizing reduction forming machine which comprises a rack. A fixed die is fixedly arranged at the top of the rack. A moving die frame is arranged in the rack in a slidingmanner. A moving die is fixedly arranged in the moving die frame. A feeding system, a hydraulic system, a steam system, an air system, a cooling water system, a die temperature control system, a vacuumizing system and a central energy distributor are further fixedly arranged on the rack. The feeding system communicates with a die cavity of the moving die through a feeding pipeline. The hydraulicsystem is connected with the moving die frame to control opening, closing and locking states of the fixed die and the moving die. The air system communicates with interiors of die cavities of the fixed die and the moving die. The central energy distributor is matched with the steam system and the air system. Meanwhile, the air system further cooperates with the feeding system to pressurize the feeding system. According to the machine, compared with the prior art, temperature adjusting can be carried out on materials added into the die cavities after die closing efficiently and effectively, thus a plastifying lamina layer is formed on the surface of a formed product, and the product quality is improved.
Description
Technical field [0001] The invention relates to the technical field of molding machine structures, in particular to a plasticizing reduction molding machine. technical background [0002] EPP(Expanded polypropylene) is a kind of high crystalline polymer / gas composite material with excellent performance, that is, polypropylene plastic foam material. With its unique and superior performance, EPP has become the fastest growing environmental protection new pressure-resistant cushioning and heat insulation material. EPP products have excellent seismic energy absorption performance, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance and heat insulation. In addition, their weight is light, which can greatly reduce the weight of goods. EPP is also an environment-friendly material, which can be recycled and reused, can be naturally degraded, and will not cause white pollution. [0003] Because EPP has the above advantages, its application field...
