Description

Technical Field

[0001] The present invention relates to the technical field of dimension detection, in particular to a dimension detection device for an injection mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, and automated operation. In the injection molding process of cylindrical objects, such as water storage barrels used in daily life, it is usually necessary to inspect the mold size before production to ensure the production qualification rate and quality.

[0003] Existing injection mold size detection devices usually collect data on the inner cavity of the mold with the cooperation of an image acquisition device. After further analysis of the collected data by a computer, qualified molds will continue to be put into production, and unqualified molds will be further measured by staff to ensure that the location where the deformation error occurs is repaired. However, the existing injection mold size detection device can only calculate the overall error of the mold cavity through image acquisition, and cannot accurately locate the location where the deformation occurs, causing the staff to need to re-measure and detect during the re-inspection process.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-8As shown, the present invention is a device for detecting the size of an injection mold, comprising a base 1, a top plate 101 being fixedly provided on the upper end of the base 1, a position adjustment mechanism, a detection mechanism and an error adjustment mechanism being provided above the base 1, the position adjustment mechanism comprising a movable beam 3 and a movable frame 306, the movable beam 3 being movably provided on the top plate 101, the movable frame 306 being movably provided at the lower end of the movable beam 3, the detection mechanism comprising a detection frame 5 and a trigger assembly, a plurality of detection heads 505 being provided on one side of the detection frame 5, the detection heads 505 being movably provided, the trigger assembly comprising a first pole piece 601 and a second pole piece 602, the first pole piece 601 and the second pole piece 602 being fixedly provided on one side of an adjustment block 6, the error adjustment mechanism comprising a connecting rod 7 and an adjustment platform 701, the adjustment platform 701 being fixedly provided at both ends of the connecting rod 7, and the connecting rod 7 being slidably provided inside the detection frame 5.

[0034] See also Figure 1-Figure 2 As shown, a placing table 2 is fixedly provided on the upper end of the base 1, and a slide groove 203 is opened inside the placing table 2. Two groups of sliders 201 are slidingly provided inside the slide groove 203.

[0035] When in use, the slider 201 and the bidirectional screw rod 204 are connected in transmission. By rotating the handle 205, the two groups of sliders 201 can move synchronously in opposite directions inside the slide groove 203. When the fixing clamp 202 is in contact with the outer side of the injection mold 8, the mold is clamped and fixed. The synchronous movement of the two groups of sliders 201 makes it easy to place the injection mold 8 in a more central position on the placement table 2, reducing the moving distance of the position adjustment mechanism and improving the detection efficiency.

[0036] See also Figure 1-Figure 3 As shown, a sliding rod 301 is fixedly provided at the upper end of the top plate 101, and the sliding rod 301 is arranged inside the moving beam 3 and is slidably arranged with the moving beam 3.

[0037] During use, the positioning probe 307 determines the position of the central axis of the injection mold 8 by collecting image data for analysis, and further the first motor 303 operates to drive the first screw rod 302 to rotate, so that the movable beam 3 slides on the slide rod 301, and the second motor 305 operates to drive the second screw rod 304 to rotate, so that the movable frame 306 slides inside the lower end of the movable beam 3. The synchronous operation of the first motor 303 and the second motor 305 can achieve precise adjustment of the position of the detection frame 5 to ensure that the central axis of the detection frame 5 during rotation is consistent with the central axis of the injection mold 8, thereby improving the detection accuracy.

[0038] See also Figure 1-Figure 4 As shown, the lower end of the movable frame 306 is rotatably provided with a telescopic component 4, the upper end of the telescopic component 4 is provided with a third motor 401, the third motor 401 is installed at the lower end of the movable frame 306, the lower end of the telescopic component 4 is provided with a positioning probe 307, and one side of the telescopic part of the telescopic component 4 is slidably connected to the detection frame 5, and one side of the detection frame 5 is provided with a rack 404, the rack 404 is meshed with the gear 403, the gear 403 is provided at the output end of the fourth motor 402, and the fourth motor 402 is installed on one side of the telescopic component 4.

[0039] When in use, the third motor 401 can drive the telescopic component 4 to rotate, so that the detection head 505 on one side of the detection frame 5 can rotate and detect the side wall of the inner cavity of the injection mold 8. The fourth motor 402 can be used to adjust the height of the detection frame 5, so that the detection frame 5 can penetrate into the bottom of the inner cavity of the injection mold 8 and perform a comprehensive inspection of its inner cavity side wall. The telescopic component 4 can move the detection frame 5 through telescopic movement, so that the detection head 505 installed on one side of the detection frame 5 is in contact with the inner cavity side wall of the injection mold 8.

[0040] See also Figure 5-Figure 8 As shown, the detection frame 5 is provided with a plurality of sliding cavities 501, each of which is slidably provided with a sliding post 502. A first spring 504 is provided on one side of the sliding post 502, and the first spring 504 is provided inside the sliding cavity 501. A connecting rod 503 is provided on the other side of the sliding post 502, and the connecting rod 503 is slidably connected to the detection frame 5. A detection head 505 is fixedly provided on one side of the connecting rod 503. A rotating cavity is provided inside the detection head 505, and a roller 506 is provided inside the rotating cavity. The roller 506 is rotatably provided inside the detection head 505. The first pole piece 601 and the second pole piece 602 are configured as an arc structure, and an insulating area is provided between the first pole piece 601 and the second pole piece 602. The first pole piece 601 and the second pole piece 602 are bonded together by a metal sheet 607 to form a closed loop. The metal sheet 607 is fixedly mounted on one side of the trigger plate 608, and the trigger plate 608 is fixedly connected to the sliding post 502.

[0041] During use, when the injection mold 8 is deformed and exceeds the standard production range, the detection head 505 is squeezed by the side wall during rotation, which pushes the connecting rod 503 to move into the interior of the detection frame 5, causing the metal sheet 607 on the trigger plate 608 to fit with the first and second pole pieces 601, 602. After the first and second pole pieces 601, 602 are closed, a path is formed to trigger the detection failure alarm system. A roller 506 rotates inside the detection head 505 to improve the smoothness of the detection head 505 when fitting and rotating with the side wall of the inner cavity of the injection mold 8. The segmented design of the detection head 505 can perform regional inspections on the injection mold 8. When a certain area is deformed, the depth position of this area can be accurately located, which facilitates re-inspection by staff and reduces the measurement area required for re-inspection. By providing a first spring 504, all detection heads 505 can be pushed to reset after the inspection is completed. The arc-shaped configuration of the first and second pole pieces 601, 602 can ensure that they are tightly combined with the metal sheet 607, avoiding poor contact and failure to accurately trigger the failure alarm system.

[0042] See also Figure 5-Figure 8 As shown, an adjustment block 6 is provided inside the detection frame 5, a movable cavity 605 is provided inside the adjustment block 6, a push rod 604 is slidingly provided inside the movable cavity 605, a second spring 606 is provided at one end of the push rod 604, and two groups of protrusions 603 are fixedly provided at the other end of the push rod 604, and one end of the two groups of protrusions 603 are respectively fitted with one side of the first pole piece 601 and the second pole piece 602.

[0043] During use, the push rod 604 is pushed by the elastic force of the second spring 606 so that the protrusion 603 fits against one side of the first pole piece 601 and the second pole piece 602, so that the first pole piece 601 and the second pole piece 602 maintain an arc structure.

[0044] See also Figure 5-Figure 7 As shown, a connecting rod 7 is fixedly provided at one end of the adjusting block 6, and the connecting rod 7 is slidably provided inside the adjusting vertical slot 705. The adjusting vertical slot 705 and the adjusting horizontal slot 706 are connected, and the adjusting vertical slot 705 and the adjusting horizontal slot 706 are both opened inside the detection frame 5. The adjusting block 6 is slidably provided inside the adjusting horizontal slot 706. Fixed blocks 703 are fixed at both ends of the detection frame 5, and a distance adjusting bolt 702 is installed inside the fixed block 703. The distance adjusting bolt 702 is transmission-connected to one end of the adjusting platform 701. A scale 704 is provided on one side of the adjusting platform 701, and the scale 704 is provided on the outside of both ends of the detection frame 5.

[0045] When in use, one end of the adjusting bolt 702 is a smooth structure and is installed inside the fixed block 703. By rotating the adjusting bolt 702, the adjusting platform 701 can be pushed to move. One end of the scale 704 is aligned with one side of the adjusting platform 701, and the moving distance can be accurately read. The movement of the adjusting platform 701 drives the connecting rod 7 to move in the adjusting vertical slot 705 and the adjusting block 6 to move in the adjusting horizontal slot 706. The movement of the adjusting block 6 creates a distance between the first pole piece 601 and the second pole piece 602 and the metal sheet 607. The distance between them is the error range triggered by the error alarm system. The error range can be adjusted by rotating the adjusting bolt 702, and the injection mold 8 is inspected according to the required error range.

[0046] A specific application of this embodiment is:

[0047] When in use, the slider 201 and the bidirectional screw rod 204 are connected in transmission. By rotating the handle 205, the two groups of sliders 201 can move synchronously in opposite directions inside the slide groove 203. When the fixing clamp 202 is in contact with the outer side of the injection mold 8, the mold is clamped and fixed. The synchronous movement of the two groups of sliders 201 makes it easy to place the injection mold 8 in a more central position on the placement table 2, reducing the moving distance of the position adjustment mechanism and improving the detection efficiency.

[0048] The positioning probe 307 determines the position of the central axis of the injection mold 8 by collecting image data for analysis. Further, the first motor 303 operates to drive the first screw rod 302 to rotate, so that the movable beam 3 slides on the slide rod 301. The second motor 305 operates to drive the second screw rod 304 to rotate, so that the movable frame 306 slides inside the lower end of the movable beam 3. The synchronous operation of the first motor 303 and the second motor 305 can achieve precise adjustment of the position of the detection frame 5 to ensure that the central axis of the detection frame 5 is consistent with the central axis of the injection mold 8 when it rotates, thereby improving the detection accuracy.

[0049] The operation of the third motor 401 can drive the telescopic component 4 to rotate, so that the detection head 505 on one side of the detection frame 5 can rotate and detect the side wall of the inner cavity of the injection mold 8. The operation of the fourth motor 402 can adjust the height of the detection frame 5, so that the detection frame 5 can penetrate into the bottom of the inner cavity of the injection mold 8 and perform a comprehensive inspection of its inner cavity side wall. The telescopic component 4 can move the detection frame 5 through telescopic movement, so that the detection head 505 installed on one side of the detection frame 5 can fit with the inner cavity side wall of the injection mold 8.

[0050] When the injection mold 8 is deformed and exceeds the standard production range, the detection head 505 is squeezed by the side wall during rotation, which pushes the connecting rod 503 to move into the detection frame 5, so that the metal sheet 607 on the trigger plate 608 fits with the first and second pole pieces 601, 602. After the first and second pole pieces 601, 602 are closed, a path is formed to trigger the detection failure alarm system. A roller 506 rotates inside the detection head 505 to improve the smoothness of the detection head 505 when it fits and rotates with the side wall of the inner cavity of the injection mold 8. The segmented design of the detection head 505 can perform regional inspections on the injection mold 8. When a certain area is deformed, the depth position of this area can be accurately located, which facilitates re-inspection by staff and reduces the measurement area required for re-inspection. By providing a first spring 504, all detection heads 505 can be pushed to reset after the inspection is completed. The arc-shaped configuration of the first and second pole pieces 601, 602 enables them to be tightly combined with the metal sheet 607, avoiding poor contact and failure to accurately trigger the failure alarm system.

[0051] The push rod 604 is pushed by the elastic force of the second spring 606 so that the protrusion 603 fits against one side of the first pole piece 601 and the second pole piece 602, so that the first pole piece 601 and the second pole piece 602 maintain an arc-shaped structure.

[0052] One end of the distance adjusting bolt 702 is a smooth structure and is installed inside the fixed block 703. By rotating the distance adjusting bolt 702, the adjusting platform 701 can be pushed to move. One end of the scale 704 is aligned with one side of the adjusting platform 701, and the moving distance can be accurately read. The movement of the adjusting platform 701 drives the connecting rod 7 to move in the adjusting vertical slot 705 and the adjusting block 6 to move in the adjusting horizontal slot 706. The movement of the adjusting block 6 creates a distance between the first pole piece 601 and the second pole piece 602 and the metal sheet 607. The distance between them is the error range triggered by the error alarm system. The distance adjusting bolt 702 is rotated to adjust the error range, and the injection mold 8 is inspected according to the required error range.
