Injection compression transfer molding is a new pallet forming technology that combines injection, extrusion plasticization and compression molding in a hybrid injection molding machine. It not only has the characteristics of injection molding trays, but also suitable for the use of waste plastic molding trays, molding glass fiber filled plastic trays. The oil-electric hybrid injection molding machine forms trays of the same type and the same specifications, and the clamping force is 1/3 of the clamping force of the injection molding tray, which improves the service life of the mold. The mold structure is complex, which increases the investment cost of the mold. According to the requirements of different principles, the plastic injection parts of the hybrid electric injection molding machine come in many forms. The clamping mechanism can be mechanical or hydraulic. Therefore, the hydraulic mold clamping mechanism is generally used to reduce the investment cost of the mold.
The oil-electric hybrid injection molding machine has the extrusion plasticization and the injection storage cylinder on the same axis, and the nozzle is a hydraulic self-locking double cylinder injection single screw extruder. The inner and outer cylinders of the injection storage cylinder move relatively, the outer cylinder is connected to the end surface of the extruder barrel, and the inner bar body of the oil-electric hybrid injection molding machine controls the storage. Among them, the low-torque high-torque hydraulic motor drive shaft in the oil-electric hybrid injection molding machine is plasticized, which is beneficial to the plasticization of the acid.
