The specific control method is as follows:

[0043] The area of ​​the plate placed on the top surface of the base 1 is detected by the area detection module 601, and is transmitted together with the area value preset by the area preset module 602 to the data comparison module 603. The data comparison module 603 performs area comparison and judgment. When the area of ​​the plate is lower than the set threshold, the first control module 7 receives the judgment information and generates a corresponding control instruction, thereby controlling the deflection of the tilt adjustment mechanism 5 to eject the plate;

[0044] The data comparison module 603 performs area comparison and judgment. When the area of ​​the plate is not less than the set threshold, the second control module 8 receives the judgment information and forms a corresponding control instruction. The second control module 8 activates the visual edge detection module 9 to identify the edge position of the plate placed on the top surface of the base 1 and transmits the offset instruction to the coordinate adjustment mechanism 4. Then, the horizontal and vertical positions of the plane where the plate is located are adjusted by the coordinate adjustment mechanism 4. At the same time, along with the adjustment of the coordinate position of the plate, the offset information is continuously received and fed back by the visual edge detection module 9 until the center of the plate is adjusted to be aligned directly below the stamping and injection molding mechanism 3.

[0051] The width of the side wall section of the punching tube 306 gradually decreases from top to bottom, so as to reduce the contact surface during contact, increase the pressure, improve the punching efficiency, and cut off the excess scraps.

[0052] When in use, the movable end at the bottom of the first electric push rod 302 extends downward, and then the shaping block 304 fixedly connected thereto is driven to punch downward through the buffer block 303, and then acts on the surface of the metal sheet placed on the top surface of the injection molding bottom plate 504. Under the continuous punching action of the buffer block 303, the local metal sheet located on the top surface of the punching groove 505 is punched into the inner cavity of the punching groove 505, and as the punching force of the buffer block 303 increases, the depth of the metal sheet sinking into the inner cavity of the punching groove 505 increases;

The first servo motor 406 is braked, and the output shaft of the first servo motor 406 drives the rotating wheel 402 fixedly connected to it to rotate. The two rotating wheels 402 rotate synchronously through the crawler drive, and then the rotating wheel 402 drives the screw rod 403 to rotate synchronously, so that the slider 405 moves along the surface of the screw rod 403 under the limit of the limit rod 404, thereby adjusting the longitudinal position of the metal sheet material clamped by the electric clamp 408.

A control method for an injection mold precision detection system, characterized in that: The specific steps are: S1, detecting the area of ​​the plate placed on the top surface of the base (1) through the area detection module (601), and transmitting it together with the area value preset by the area preset module (602) to the data comparison module (603), the data comparison module (603) performs area comparison and judgment, and when the area of ​​the plate is lower than the set threshold value, the first control module (7) receives the judgment information and generates a corresponding control instruction, thereby controlling the deflection of the tilt adjustment mechanism (5) to eject the plate; S2, performing area comparison and determination through the data comparison module (603), when the area of ​​the plate is not less than the set threshold, receiving the determination information through the second control module (8) and generating corresponding control instructions, activating the visual edge detection module (9) through the second control module (8) to identify the edge position of the plate placed on the top surface of the base (1) and transmitting the offset instruction to the coordinate adjustment mechanism (4), and then adjusting the horizontal and vertical positions of the plane where the plate is located through the coordinate adjustment mechanism (4), and simultaneously, along with the adjustment of the coordinate position of the plate, the offset information is continuously received and fed back by the visual edge detection module (9) until the center of the plate is adjusted to be aligned with the bottom of the stamping and injection molding mechanism (3); S3, after the plate position is calibrated, the positioning information is transmitted to the third control module (10) through the visual edge detection module (9), and then the third control module (10) forms a control instruction, and then the third control module (10) activates the stamping and injection molding mechanism (3) and the deformation detection module (11) respectively, wherein the output end at the bottom of the stamping and injection molding mechanism (3) performs stamping and injection molding of the injection molded part, and the surface deformation of the injection molded part is fed back to the deformation detection module (11) and received by it, and the deformation detection module (11) analyzes the received data to control the magnitude of the force applied by the stamping and injection molding mechanism (3) to the surface of the injection molded part; S4, after the deformation detection module (11) detects that the deformation of the product is qualified, the information is transmitted to the first control module (7), and then the first control module (7) controls the deflection of the tilt adjustment mechanism (5) again to eject the injection molded part.
