Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 This embodiment provides a technical solution: a high-efficiency detection device for the dimensional accuracy of injection molds, including a base 1 and a controller 3. The upper end of the base 1 is provided with a mounting bracket 2, and the middle part of the upper end of the base 1 is provided with a placement platform 4. It also includes a detection mechanism 5.

[0019] The detection mechanism 5 includes an adjusting seat 54, a mounting seat 55, and a transmission plate 56. The mounting seats 55 are slidably connected to the right wall of the mounting frame 2. The left end of each mounting seat 55 is rotatably connected to a transmission plate 56, and the left end of each transmission plate 56 is rotatably connected to an adjusting seat 54. The middle of the two transmission plates 56 is rotatably connected by a pin. The detection mechanism 5 also includes a crossbar 51, a connecting seat 52, and a mounting rod 53. The crossbar 51 is located on the upper side inside the mounting frame 2 and is slidably connected to corresponding sliding holes on the right end of the connecting seat 52. A sliding hole is opened on the lower side of the right end of the connecting seat 52. An installation rod 53 is installed inside the chute. Adjustment seats 54 are slidably connected to the front and rear sides of the outer arc surface of the installation rod 53, and both adjustment seats 54 are slidably connected to the inner wall of the chute. The detection mechanism 5 also includes an electric push rod 57 and a laser scanner 58. The electric push rod 57 is located at the lower end of the connecting seat 52. The electric push rod 57 is located in the installation groove opened in the middle of the bottom wall of the mounting frame 2. The laser scanner 58 is installed at the lower end of the telescopic end of the electric push rod 57. The input end of the electric push rod 57 is electrically connected to the output end of the controller 3. The laser scanner 58 is bidirectionally electrically connected to the controller 3.

[0020] Specifically: a bidirectional screw 6 is rotatably connected to the right side inside the mounting bracket 2, and the mounting base 55 is threaded to the front and rear sides of the outer arc surface of the bidirectional screw 6 through the threaded hole on the right side of its front end. During the rotation of the bidirectional screw 6, it will drive the two mounting bases 55 to move towards the end closer to the center of the base 1.

[0021] Among them: a servo motor 7 is set on the right side of the rear end of the mounting bracket 2. The front end of the output shaft of the servo motor 7 is fixedly connected to the rear end of the bidirectional screw 6. The input end of the servo motor 7 is electrically connected to the output end of the controller 3. Through the control of the controller 3, the servo motor 7 starts to run, and the output shaft of the servo motor 7 drives the bidirectional screw 6 to rotate.

[0022] The base 1 has a fixed plate 8 on its left and right sides. An electric push rod 9 is installed on the upper side of the fixed plate 8 near the center of the base 1. A clamping plate 10 is installed on the telescopic end of the electric push rod 9 near the center of the base 1. The input end of the electric push rod 9 is electrically connected to the output end of the controller 3. The electric push rod 9 starts to run and extends its telescopic end, thereby moving the two clamping plates 10. At this time, the distance between the two clamping plates 10 gradually decreases. Finally, the clamping plates 10 near the center of the base 1 come into contact with the outer surface of the injection mold, thereby achieving the limiting and fixing of the injection mold.

[0023] The working principle of this utility model is as follows:

[0024] During the use of the high-efficiency injection mold dimensional accuracy detection device, the injection mold that needs to be dimensionally accurate is placed on the upper end of the placement table 4 through external equipment.

[0025] Then, through the control of the controller 3, the electric push rod 9 starts to run. The telescopic end of the electric push rod 9 extends, thereby driving the two clamping plates 10 to move. At this time, the distance between the two clamping plates 10 will gradually decrease. Finally, the end of the clamping plate 10 that is close to the center of the base 1 contacts the outer surface of the injection mold, thereby achieving the limiting and fixing of the injection mold.

[0026] Then, under the control of controller 3, electric push rod 2 57 starts to run, and the telescopic end of electric push rod 2 57 extends, thereby causing laser scanner 58 to move downward, thereby adjusting the height of laser scanner 58. After the height of laser scanner 58 is adjusted, laser scanner 58 starts to run under the control of controller 3.

[0027] At the same time, the servo motor 7 starts running under the control of the controller 3. The output shaft of the servo motor 7 drives the bidirectional screw 6 to rotate. During the rotation, the bidirectional screw 6 will drive the two mounting seats 55 to move towards the end closer to the center of the base 1. At this time, the distance between the two mounting seats 55 gradually decreases, which will also cause the distance between the front and rear sides of the two transmission plates 56 to decrease. At this time, the transmission plates 56 will push the adjusting seat 54 to the left due to the decrease in the distance between the front and rear sides, so that the adjusting seat 54 drives the connecting seat 52 to move to the left. The connecting seat 52 will then drive the laser scanner 58 to move to the left through the electric push rod 57, thereby adjusting the position of the laser scanner 58.

[0028] During the movement of the laser scanner 58, it emits laser beams that illuminate the surface of the injection mold. After the laser beams are reflected off the surface of the injection mold, they are captured by the laser scanner 58. The intensity and angle of the reflected light are related to the shape and position of the injection mold surface. By measuring the return time and angle of the reflected light, the laser scanner 58 calculates the three-dimensional coordinates of each point on the injection mold surface. Then, it generates a high-precision three-dimensional model based on these three-dimensional coordinates. Afterward, the laser scanner 58 transmits the scanned data to the controller 3. The controller 3 compares the measurement results with the initial design data of the injection mold and finally calculates the dimensional deviation.

[0029] It is worth noting that the controller 3 disclosed in the above embodiments can be an STM8S207S8T6C, the servo motor 7 can be an ECMA-C20604RS, the electric linear actuator 9 and the electric linear actuator 57 can be YRJ0905, and the laser scanner 58 can be a Z+F 5016. The controller 3 controls the operation of the servo motor 7, the electric linear actuator 9, the electric linear actuator 57 and the laser scanner 58 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
