Polishing device and method capable of removing burrs on workpiece in all directions after injection molding completion

Abstract

The invention relates to the technical field of injection molding, and discloses a polishing device capable of removing burrs on a workpiece in all directions after injection molding completion. The polishing device comprises an equipment shell, a rotor shaft is movably connected to the interior of the equipment shell, rotating blades are fixedly connected to the outer side of the rotor shaft, a mounting groove is formed inside the rotor shaft, a reset spring is fixedly connected to the interior of the mounting groove, a first moving contact is fixedly connected to the outer side of the reset spring, a first fixed contact is fixedly connected to the interior of the mounting groove, an induction groove is formed inside the equipment shell, and a vibration spring is fixedly connected to the interior of the induction groove. A first magnetic block and a second magnetic block are close to each other, so that a circuit is connected after a second moving contact and a second fixed contact are in contact, an electrostriction shaft is electrified to extend, a power connection plug is pushed out, a power connection column and a conductive source in a power supply socket are disconnected, the rotor shaft stops rotating, and the device is prevented from being further damaged.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a grinding device and method capable of deburring workpieces in all directions after injection molding is completed. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. After plastic injection molding, due to the limited precision of the mold, the excess injection plastic will overflow from the edge of the mold, so some burrs will appear on the injection molded product. Usually, the burr needs to be polished in all directions before it can be sold and used as a qualified finished product. Among them, the pneumatic grinder is suitable for operation at various angles, with small size, high speed, high grinding efficiency, low noise, small vibration, and strong dust suction. Effect, long-term use without fatigue characteristics, but after the existing grin...

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. After plastic injection molding, due to the limited precision of the mold, the excess injection plastic will overflow from the edge of the mold, so some burrs will appear on the injection molded product. Usually, the burr needs to be polished in all directions before it can be sold and used as a qualified finished product. Among them, the pneumatic grinder is suitable for operation at various angles, with small size, high speed, high grinding efficiency, low noise, small vibration, and strong dust suction. Effect, long-term use without fatigue characteristics, but after the existing grinding device is used for a period of time, due to mechanical failure, the blade will break, and the blade will cause debris to be stuck between the rotor and the cylinder after the blade breaks. If it cannot be found in time Otherwise, it will cause damage to the cylinder and increase the maintenance cost
