Description

Technical Field

[0001] The invention relates to the technical field of mold size measurement, and in particular to a mold size measurement device and method for processing an injection mold for a vehicle lamp. Background Art

[0002] The image measuring instrument uses the principle of optical imaging to capture images through a camera and analyze and calculate them by a computer-aided measurement system to determine the specific size of the workpiece. At present, in the process of processing the injection mold of the headlight, due to the irregular curved surface of the headlight, the depth of the groove varies. When using the image measuring instrument to measure the size of the groove, it is easy to cause shadows inside the groove due to the unchanged illumination angle, resulting in deviations in the measurement results. There are also image measuring instruments installed with adjustable light source angles, but when illuminating the headlight groove on the mold, the light is easily blocked by the grooves of different heights, which can only reduce the scope of the shadow, and the effect is relatively general; For example, the image measuring instrument disclosed by announcement number CN207622694U has the problem that the illumination angle remains unchanged. When illuminating the groove of the headlight mold with a difficult depth, the light is easily blocked by the grooves of different heights, and shadows exist in the grooves, resulting in deviations in the measurement results. The light source angle adjustment mechanism and image measuring instrument disclosed by announcement number CN205899113U, although the application can adjust the light source angle, the height of the light source is fixed. When illuminating the groove of the headlight mold with a difficult depth, the light is easily blocked by the grooves of different heights, and shadows still exist in the grooves. If the height of the light source can also be adjusted, the wiring requirements for the wires will be more stringent and difficult. Therefore, a mold size measuring device and method for processing an automobile lamp injection mold are proposed. Summary of the invention

[0014] The present invention provides a mold size measuring device and method for processing a car lamp injection mold. Compared with the prior art, the device has the following beneficial effects: (1) The mold size measuring device and method for processing a headlight injection mold are as follows: a headlight injection mold body to be inspected is placed for inspection; a ring light source is used in combination with a point light source to illuminate the groove of the mold body; an image measuring instrument body measures key data such as the depth and angle of the irregular headlight groove on the mold body, thereby determining whether the size of the processed mold body meets the requirements; the headlight injection mold body to be inspected is fixed by a fixing plate and then transferred to the inspection position of the image measuring instrument body, thereby ensuring that the position of the mold is consistent each time, reducing the position error caused by the different placement positions each time, thereby improving the accuracy of the measurement result, preventing the mold body from moving or vibrating during the measurement process, ensuring that the image measuring instrument obtains a clear and accurate image, and the headlight injection mold body to be measured is always in a preset position, so that the image measuring instrument body can be more easily calibrated initially, and can maintain accuracy for a long time after calibration, thereby saving inspection time and improving inspection efficiency.

The telescopic sleeve 3 and the telescopic rod 33 are slidably adapted to each other so that the telescopic sleeve 3 can only move in a straight line along the telescopic rod 33 when moving. The fixed plate 214 is driven to move by the telescopic sleeve 3 so that the suction cup installed on the side of the fixed plate 214 can be close to the side wall of the mold body 101.

[0026] See also Fig.12 , Fig.13 , the present invention provides the following technical solutions: Embodiment 3: The technical solutions of this embodiment that are different from the above embodiments include: The support rod 212 and the sliding sleeve 213 are no longer Figure 7 , Figure 8 Instead of being arranged in the position shown in the figure, the sliding sleeve 213 and the support rod 212 are arranged on the back side of the fixed plate 214 relative to the surface where the suction cup is located, and the sliding sleeve 213 is movably installed on the fixed plate 214 through a fixed shaft, and a limit plate is installed on the fixed shaft. The fixed shaft with the limit plate installed is similar to a cattail fan. A stop rod is arranged on the lower side of the limit plate, and the stop rod is used to block the limit plate to limit the rotation angle of the fixed shaft. The image measuring instrument body 1 is provided with an adjustment component for changing the tilt angle of the mold body 101, and the adjustment component includes: a positioning rod 5, a sliding column 51, a moving block 52, a limiting rod 53, and a spring 54; One end of the positioning rod 5 is fixed to the side wall of the output shaft 21, and the positioning rod 5 is located in the image measuring instrument body 1 to transmit the power for changing the tilt angle of the mold body 101; The bottom of the sliding column 51 is fixedly mounted on the top of the positioning rod 5, driving the mold body 101 to change its tilt angle; The bottom inclined surface of the moving block 52 slides against the top of the sliding column 51, and the top of the moving block 52 slides against the bottom of the mold body 101 to assist in changing the inclination angle of the mold body 101; One end of the limit rod 53 is fixedly mounted on the side wall of the moving block 52, and the other end of the limit rod 53 is slidably inserted into the image measuring instrument body 1.

[0027] When in use, when the mold body 101 to be inspected is transferred to the inspection position; The mold body 101 and the moving block 52 are in sliding contact with each other, and the mold body 101 pushes the moving block 52 downward for a short distance, so that the moving block 52 is partially retracted into the image measuring instrument body 1, and the limiting rod 53 is slidably adapted to the image measuring instrument body 1, so that the moving block 52 can only move in a straight line when moving downward, so that the bottom inclined surface of part of the moving block 52 can be on the moving path of the sliding column 51; The lower electromagnet 29 and the upper electromagnet 210 are energized to make the upper electromagnet 210 and the lower electromagnet 29 magnetically repel each other, and the support plate 26 is driven by the lower electromagnet 29 to move linearly downward along the guide rod 27, so that the support plate 26 drives the movable ring 23 to separate from the upper pressure plate 22.

The positioning rod 5 drives the sliding column 51 to rotate, and the sliding column 51 and the bottom inclined surface of the moving block 52 slide and abut, so that the sliding column 51 can intermittently push the moving block 52 upward, so that the moving block 52 drives the mold body 101 to move upward. After the sliding column 51 is separated from the moving block 52, the moving block 52 is reset under the action of the spring 2 54. After completing the measurement of the current mold body 101, the mold body 101 is removed from the moving block 52, and the moving block 52 is reset to the position under the action of the spring 2 54. Figure 2 Status shown; During the deflection process, the mold body 101 and the fixed plate 214 rotate within a certain angle range with the fixed axis as the axis. By deflecting the mold body 101, the headlight groove can show its entire appearance under the illumination of the ring light source 11 and the point light source 12, avoiding the appearance of internal shadows that affect the detection results.

[0028] In another embodiment different from the above-mentioned embodiment, a limit plate is also installed at the bottom of the telescopic rod 33, and a stop rod is also arranged directly below the limit plate. The telescopic rod 33 is movably mounted on the side wall of the extension sleeve 34 through a movable seat. The movable seat is composed of a movable shaft and two mounting plates. The two mounting plates are respectively located at the two ends of the movable shaft. The movable shaft is inserted into the telescopic rod 33, so that the telescopic rod 33 can be kept in the position without external force. Fig. 9 In the horizontal state shown, when an external force is applied, the telescopic rod 33 can be turned upward with the movable seat as the axis, so that the telescopic rod 33 and the telescopic sleeve 3 on one side are contracted, and the extension sleeve 34 and the extension rod 35 are contracted as well, and the telescopic rod 33 and the telescopic sleeve 3 on the other side are extended, and the extension sleeve 34 and the extension rod 35 are extended as well; The moving blocks 52 are arranged in four groups, which are distributed on the table of the image measuring instrument body 1 in a circle. Figure 1 When the two groups of moving blocks 52 at the shown position are in contact, the mold body 101 deflects left and right. When the sliding column 51 is in contact with the other two groups of moving blocks 52, the mold body 101 deflects front and back, so that the headlight groove on the mold body 101 can be fully illuminated by the annular light source 11 and the point light source 12 at multiple angles, avoiding shadows inside the groove that affect the detection results.
