Magnetic core forming device and forming process for laser printer

Abstract

The invention discloses a magnetic core forming device and a forming process for a laser printer. The device comprises an extruder barrel, extrusion screws, a machine head, an evacuation mold core, a sizing device, an electromagnetic orientation device, a cooling device, a cooling water path, a traction device and a cutting device, wherein the front end of the machine head is connected with the extruder barrel; the extrusion screws are arranged in the center of the extruder barrel; the sizing device, the cooling device, the traction device and the cutting device are arranged in sequence at the back end of the machine head; the electromagnetic orientation device is arranged in the sizing device; the cooling water path is formed in the cooling device; and the evacuation mold core passing through the machine head, the electromagnetic orientation device, the cooling water path, the traction device and the cutting device are arranged at the back ends of the extrusion screws. A conventional forming mechanism is changed, and continuous forming is performed in an extrusion way. Meanwhile, hollow evacuation can be performed in the forming way, so that materials and the production cost are saved greatly, and the production efficiency is maximized.

Description

technical field [0001] The invention relates to the technical field of magnetic core molding, in particular to a laser printer magnetic core molding device and a molding process. Background technique [0002] At present, the magnetic core molding method is injection molding. The magnetic particles are melted into a molten state by an injection molding machine, and injected into the mold by magnetic field orientation molding. The injection molding time and cooling time are long, and it is easy to deform after being taken out. In the case of bending, etc., the actual production capacity is not high, and the pass rate is relatively low. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a laser printer magnetic core forming device and forming process, which changes the traditional forming mechanism and performs continuous forming by means of extrusion. At the same time, the forming method can carr...
