[0030] like Figures 1 to 3 As shown, a preferred embodiment of the present application provides an injection molding product correction mechanism, characterized in that it includes: a frame 1, a material picking assembly and a correction assembly, the material picking assembly includes a supporting mechanism that can be lifted and lowered on the frame 1, and a clamping mechanism installed on the supporting mechanism for fixing the injection molding product; the correction assembly includes an correction plate 13 that can be movably installed on the frame 1, a lifting unit 7 that is transmission-connected to the supporting mechanism, and a cooling unit installed on the side of the correction plate 13; the lifting unit 7 is used to drive the material picking assembly to move relative to the correction plate 13 so as to clamp the injection molding product between the supporting mechanism and the correction plate 13 for fixing, and the cooling unit is used to cool and correct the injection molding product.

[0031] In this embodiment, the material taking component fixes the injection molded product through the clamping mechanism, moves relative to the orthopedic pressure plate 13 under the action of the lifting unit 7, extrude and shape the injection molded product through the bearing mechanism and the orthopedic pressure plate 13, and starts the cooling unit to cool and shape the injection molded product after shaping. The cooling characteristics of the material are used to achieve efficient and accurate automated orthopedic operations, thereby improving production efficiency and product quality.

[0032] Specifically, the bearing mechanism includes a lifting bracket 3 that is transmission-connected to the lifting unit 7 and a contour-bearing plate 2 mounted on the lifting bracket 3. Two contour-bearing plates 2 are provided, which are respectively provided on both sides of the lifting bracket 3. By providing two contour-bearing plates 2 on the lifting bracket 3, multiple injection molded products can be cooled and shaped at the same time, thereby improving the shaped-shaped efficiency.

[0033] like Figure 2 As shown, in this embodiment, the contoured carrier plate 2 is used to fix the injection molded product with the orthopedic pressure plate 13 when the jacking unit 7 drives the material taking component to move relative to the orthopedic pressure plate 13. The injection molded product is fixed on the contoured carrier plate 2 by the clamping mechanism, and the material taking component moves relative to the orthopedic pressure plate 13 under the drive of the jacking unit 7, and the contoured carrier plate 2 and the orthopedic pressure plate 13 squeeze and fix the injection molded product.

[0034] Specifically, a through hole is provided on the contoured carrier plate 2, and the clamping mechanism includes a clamping jaw 4 inserted in the through hole for fixing the injection molded product, and a clamping cylinder 5 which is transmission-connected with the clamping jaw 4 and is used to control the extension of the clamping jaw 4.

[0035] Specifically, the contoured support plate 2 is mounted on the lifting bracket 3 through a guide column 6. The guide column 6 is elastic. When the corrective mechanism of the injection molded product enters the injection molding machine and the injection molded product needs to be taken out, the guide column 6 is compressed, and the clamping jaws 4 extend from the through hole and extend into the groove opened in the injection molded product. After the clamping jaws 4 extend in the injection molded product, the corrective mechanism of the injection molded product leaves the injection molding machine, and the guide column 6 rebounds. The injection molded product is fixed on the contoured support plate 2 under the control of the clamping jaws 4 and the rebound force of the guide column 6.

[0036] Specifically, the profiling carrier plate 2 is also equipped with an orthopedic station 21 for cooperating with the orthopedic pressure plate 13 to extrude and orthopedic the injection molded product. The orthopedic station 21 is installed around the through hole. When the injection molded product is fixed on the profiling carrier plate 2, it is specifically fixed on the orthopedic station 21, and the side of the orthopedic station 21 is equipped with an adjustable limit block 22 for adjusting the contour of the orthopedic station 21. The adjustable limit block 22 can adjust the contour size of the orthopedic station 21 according to the time shrinkage of the product, ensuring that the contours of the injection molded product in the X and Y directions are corrected according to the set values.

[0037] Specifically, the material picking assembly also includes an in-mold positioning guide column fixed to the lifting unit 7, which is used to locate the position of the injection molded product in the injection molding machine when the mechanism enters the injection molding machine to pick up the injection molded product, so as to facilitate the material picking assembly to take out the injection molded product.

[0038] Specifically, the contoured carrier plate 2 is also provided with an optical fiber sensing bracket 23 for detecting whether the injection molded product is taken out from the injection molding machine and placed on the contoured carrier plate 2 , and a guide pin 24 for extrusion-matching and limiting the position with the orthopedic pressure plate 13 .

[0039] like Figure 3 As shown, in this embodiment, the orthopedic assembly includes an orthopedic support frame 12 movably mounted on the frame 1, an orthopedic pressure plate 13 mounted on the top of the orthopedic support frame 12, and the bottom of the orthopedic support frame 12 is connected to the support frame driving unit. The orthopedic support frame 12 is used to form the orthopedic pressure plate 13, and the orthopedic pressure plate 13 is used to extrude with the profiling bearing plate 2 to complete the shaping of the injection molded product. The support frame driving unit is used to drive the orthopedic pressure plate 13 to move to the top of the profiling bearing plate 2, and the orthopedic pressure plate 13 and the profiling bearing plate 2 are on the same axis.

[0040] Specifically, the support frame driving unit includes a movable slide rail 9 installed on the frame 1, a sliding cylinder 8 transmission-connected to the movable slide rail 9, and a limit block 11 for limiting the moving distance of the movable slide rail 9. The bottom of the orthopedic support frame 12 is connected to the movable slide rail 9, and the limit block 11 is installed on the frame 1.

[0041] Specifically, the movable slide rail 9 also includes a sliding link plate 10, and the orthopedic support frame 12 is fixed on the sliding link plate 10. Through the setting of the sliding link plate 10, the movable slide rail 9 has higher stability and higher movement accuracy when moving, making it more convenient to align the contoured bearing plate 2 with the orthopedic pressure plate 13.

[0042] Specifically, the limit block 11 is installed on the moving path of the sliding link plate 10, and a detection module is installed on the limit block 11. When the orthopedic pressure plate 13 moves to the limit block 11 under the drive of the sliding cylinder 8, the sliding cylinder 8 stops driving, and the detection module is electrically connected to the lifting unit 7 to control the action of the lifting unit 7.

[0043] Specifically, two orthopedic support frames 12, orthopedic pressure plates 13, movable slide rails 9, sliding link plates 10 and limit blocks 11 are each provided, symmetrically arranged relative to the central axis of the frame 1. When the sliding cylinder 8 is started, the two orthopedic pressure plates 13 are driven to move relative to or toward each other.

[0047] Step 1: The six-axis manipulator drives the injection molded product correction mechanism into the injection molding machine, and the contoured carrier plate 2 is placed against the injection molded product through the positioning guide column.

[0048] Step 2: The clamping cylinder 5 is actuated, and the clamping jaws 4 extend into the injection molded product and stretch inside the injection molded product.

[0049] Step 3: The six-axis manipulator withdraws and the guide column 6 rebounds, so that the injection molded product is fixed on the orthopedic station 21.

[0050] Step 4: Adjust the adjustable limit block 22 to correct the contours of the injection molded product in the X and Y directions according to the set values, and use the sensing optical fiber to detect the injection molded product on the profiling carrier plate 2 to determine whether it is fixed on the profiling carrier plate 2.

[0051] Step 5: The sliding cylinder 8 is activated to drive the orthopedic support frame 12 and the orthopedic pressure plate 13 to move on the movable slide rail 9. After they move above the limit block 11, the lifting unit 7 is activated.

[0052] Step 6: The lifting unit 7 drives the material taking assembly to move relative to the orthopedic pressure plate 13 , so that the injection molded workpiece is fixed between the orthopedic station 21 and the orthopedic pressure plate 13 .

[0053] Step 7: The cooling unit is activated to cool and correct the extruded injection molded product.
