7. An automatic shaping and defective product distinguishing device for plastic products according to claim 6, characterized in that: Inside the frame (1), a sliding plate (26) is provided. On both outer walls of the sliding plate (26), sliding members (28) are connected through bearings. On both inner walls of the frame (1), vertical sliding rails (27) are fixedly connected. The sliding members (28) are respectively slidably connected to the vertical sliding rails (27). On both inner walls of the frame (1), horizontal sliding rails (29) are fixedly connected. The sliding members (28) are respectively slidably connected to the horizontal sliding rails (29). On one inner wall of the frame (1), a push-pull cylinder (32) is fixedly connected. The output end of the push-pull cylinder (32) is fixedly connected to the sliding member (28). At the bottom of the sliding plate (26), a defective product area (25) is provided.

8. An automatic shaping and defective product distinguishing device for plastic products according to claim 7, characterized in that: Inside the frame (1), a control box (24) is provided. On one outer wall of the frame (1), a display screen (23) is fixedly connected. The display screen (23), the position sensor (39), and the inductor (37) are respectively electrically connected to the control box (24) through wires.

9. A method for using an automatic shaping and defective product distinguishing device for plastic products, characterized in that, applied to the automatic shaping and defective product distinguishing device for plastic products according to claim 8, includes the following steps: S1. Drive the first clamping plate (8) to move through the first clamping cylinder (7), so that the first clamping plate (8) clamps and fixes the plastic product presented by the manipulator, and then drive the rear cross plate (4) and the plastic product to move through the first reciprocating mechanism (5); S2. Rotate the turning plate (6) through the turning mechanism (36) to make the plastic product in a horizontal state. Drive the turning mechanism (36) and the plastic product to move through the rear cylinder (38), so that the turning mechanism (36) slides downward on one side of the slide rail plate (35), and the four corners of the plastic product are located inside the matching grooves (10) of the support blocks (9); S3. Drive the lifting plate to move through the detection cylinder (30), so that the sensor (37) on the lifting plate contacts the plastic product. Control the sensor (37) to detect whether there is a lack of nuts on the product through the control box (24). After the detection is completed, the detection cylinder (30) resets, and at the same time, the second reciprocating mechanism (15) drives the moving plate (12) to move to the bottom of the pressing plate (19); S4. Drive the pressing plate (19) to move downward through the front cylinder (18), so that the pressing plate (19) shapes the plastic product by pressure. After shaping, drive the second clamping plate (21) to clamp the plastic product through the second clamping cylinder (20); S5. Drive the plastic product to move upward through the front cylinder (18), and then drive the moving plate (12) to reset by using the second reciprocating mechanism (15); S5.

1. If the sensor (37) detects that there is no lack of nuts on the plastic product, drive the clamping plate to reset through the second clamping cylinder (20), so that the plastic product slides down through the slide plate (26); S5.

2. If the sensor (37) detects that the plastic product is a defective product lacking nuts, drive the slide plate (26) to move through the push-pull cylinder (32), so that the slide plate (26) flips through the horizontal slide rail (29) and the vertical slide rail (27), and then drive the clamping plate to reset through the second clamping cylinder (20), so that the defective plastic product falls into the defective product area (25).
