Extrusion device for 3D printing of vehicles
ActiveCN224335069UManufacturing heating elementsManufacturing auxillary operationsElectric machineDrive motor
This utility model relates to the field of automotive sculpture technology, and discloses an extrusion device for 3D printing of vehicles, including a barrel. A drive motor is fixedly installed on the top of the barrel, and a spiral feed rod is rotatably arranged inside the barrel. The output end of the drive motor is fixedly connected to the top end of the spiral feed rod. A feed pipe is connected to the side of the barrel, and an electric heating jacket is fitted on the outer wall of the barrel. An extrusion nozzle is connected to the bottom of the barrel. An airflow is generated by a micro fan. The airflow enters the cooling cylinder through a blower pipe, and is then slowed and divided by an annular flexible air plate to diffuse the airflow. It then undergoes secondary slowing and division by a bowl-shaped flexible air plate. The low-speed and wide-range airflow is blown from multiple points towards the high-temperature material extruded from the extrusion nozzle, which can both cool the material and avoid the problem of the material being blown apart by a high-speed airflow.
