An automatic sliding door mechanism for an injection molding machine, which can automatically open and close a sliding door and is not easy to damage a machine body.

The utility model discloses a concrete implementation scheme: including organism 1 and sliding door 2, be equipped with control box 3 and guide rail 4 on the organism 1, be equipped with controller 5 and cylinder 6 on the control box 3, sliding door 2 and guide rail 4 sliding connection push away, cylinder 6 slides on guide rail 4 with pushing away door 2 connection and drive sliding door 2, be equipped with the infrared inductor 7 that is used for monitoring the operating condition of injection molding machine in the organism 1, infrared inductor 7 and cylinder 6 all with controller 5 electric connection, still be equipped with positioner 8 and buffer 9 on the organism 1, positioner 8 and buffer 9 are arranged respectively in sliding door 2 both sides and with sliding door 2 cooperation.

After the infrared sensor 7 detects that the injection molding of the workpiece is finished, information is fed back to the controller 5, the controller 5 controls the cylinder 6 to be started, so that the push door 2 is opened by the cylinder 6, then the workpiece is taken down by a worker, and after the workpiece is taken down, the push door 2 is reset and closed by the pushing of the cylinder 6, so that the worker is not required to manually open and close the push door 2, and potential safety hazards generated when the worker pushes the push door 2 are greatly reduced; when the sliding door 2 is opened and closed, two sides of the sliding door 2 are respectively collided and abutted with the positioning device 8 and the buffer device 9, and the positioning device 8 and the buffer device 9 buffer and decompose the impact force generated by the sliding door 2, so that the sliding door 2 is not easy to damage the machine body 1 when opened and closed; when the sliding door 2 is opened, the sliding door slides on the machine body 1 through the sliding rail, so that the opening and closing of the sliding door 2 are smoother.

The positioning device 8 comprises a first positioning piece 10 and a second positioning piece 11, the positioning device 8 is arranged between the control box 3 and the sliding door 2, the first positioning piece 10 comprises a positioning seat 12 fixed on the machine body 1, a first magnet 13 embedded on the positioning seat 12 and a rubber ring 14 adhered on the positioning seat 12, the first magnet 13 is arranged in the rubber ring 14, the second positioning piece 11 comprises a positioning plate 15 fixed on the side end of the sliding door 2 and a second magnet 16 embedded on the positioning plate 15, and the first magnet 13 corresponds to and is mutually exclusive with the second magnet 16.

When the sliding door 2 is opened, the sliding door moves towards the direction of the positioning device 8 under the action of the air cylinder 6 until the sliding door 2 is close to the positioning device 8, namely the second positioning piece 11 is close to the first positioning piece 10, and the first magnet 13 and the second magnet 16 are close to each other and mutually exclusive, so that the inertia force generated by the sliding door 2 is buffered; the sliding door 2 impacts the rubber ring 14, the rubber ring 14 is extruded, and therefore the inertia force generated by sliding the sliding door 2 is buffered; the rubber ring 14 protects the magnets and prevents the two magnets from colliding and being damaged; by the arrangement, when the push door 2 is opened, the machine body 1 is not easily damaged by the inertia force generated by the push door 2.
