DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the automatic component injection mold tightening mechanism provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the structure of the lower pressure column of the tightening mechanism of the injection mold of the automation component shown; Figure 3 for Figure 1 The structural schematic diagram of the diagonal bracing mechanism of the automatic component injection mold tightening mechanism shown. The automatic component injection mold tightening mechanism comprises a placement table 1 and a plurality of diagonal bracing mechanisms 6;

[0022] A plurality of vertical poles 2 are respectively and vertically fixedly connected to the corners of the upper surface of the placing table 1. The top ends of the plurality of vertical poles 2 are horizontally fixedly connected to a horizontal plate 3. The top end of the horizontal plate 3 is vertically penetrated with a mounting hole. The inside of the mounting hole is vertically fixedly connected to a hydraulic rod 4.

[0023] A lower pressure column 5, the lower pressure column 5 is vertically fixedly connected to the bottom end of the hydraulic rod 4, and a plurality of diagonal bracing mechanisms 6 are arranged on the outer surface of the lower pressure column 5;

[0024] The structures of multiple diagonal bracing mechanisms 6 are all the same, one of the diagonal bracing mechanisms 6 includes a fixed block 61 fixedly connected to the middle and bottom ends of the outer surface of the lower pressure column 5, a threaded rod 62 is vertically rotatably connected between the two fixed blocks 61, the outer surface of the threaded rod 62 is threadedly connected to a threaded sleeve 63 slidably connected to the outer surface of the lower pressure column 5, the top end of the outer surface of the lower pressure column 5 is fixedly connected to a fixed seat 66, the bottom end of the fixed seat 66 is rotatably connected to a diagonal bracing rod 67, the upper end of the inner surface of the diagonal bracing rod 67 is fixedly connected to an upper connecting seat 68, the outer end of the upper connecting seat 68 is rotatably connected to a connecting rod 65, the bottom end of the connecting rod 65 is rotatably connected to a lower connecting seat 64, and the other end of the lower connecting seat 64 is fixedly connected to the outer surface of the threaded sleeve 63.

[0025] When the diagonal support mechanism 6 in the device is actually used, the threaded sleeve 63 can be driven to move along its length direction by rotating the threaded rod 62. During the movement of the threaded sleeve 63, the lower connecting seat 64 at its outer end will drive the bottom end of the connecting rod 65 to move in the vertical direction. During its upward movement, it can drive the bottom end of the diagonal support rod 67 to expand outward, thereby adjusting the extension length of the diagonal support rod 67. When the device is actually used, the extension distance of multiple diagonal support mechanisms 6 can be adjusted according to the actual size of the mold. When pressing down, multiple pressure points can be created through the bottom ends of multiple diagonal support rods 67, thereby fully covering the mold and ensuring the quality of the final product.

[0026] When pressing down, the hydraulic rod 4 drives the pressing column 5 to move downward, and also drives the plurality of diagonal support mechanisms 6 to move downward synchronously.

[0027] The bottom ends of the plurality of diagonal support rods 67 are rotatably connected to diagonal support seats 610 .

[0028] The bottom end of the fixing block 61 at the bottom end is fixedly connected with a servo motor 69 , and the output shaft of the servo motor 69 rotatably passes through the fixing block 61 and is fixedly connected with the bottom end of the threaded rod 62 .

[0029] The diagonal support seat 610 can fit with the mold to ensure the force direction when the mold is pressed.

[0030] When the servo motor 69 is running, it can drive the threaded rod 62 to rotate, and it is a power component.

[0031] A threaded hole 7 is vertically formed at the bottom end of the pressing column 5 , a screw rod 8 is threadedly connected to the inside of the threaded hole 7 , and a pressing seat 11 is fixedly connected to the bottom end of the screw rod 8 .

[0032] The top of the threaded hole 7 is fixedly connected to an adjusting motor 9 , the bottom end of the output shaft of the adjusting motor 9 is vertically fixedly connected to a telescopic rod 10 , and the bottom end of the telescopic rod 10 is fixedly connected to the top of the screw rod 8 .

[0033] Since the horizontal plane at the bottom end of the diagonal support mechanism 6 will change during adjustment, the horizontal plane at the pressure point in the middle also needs to be synchronized. When adjusting the height of the lower pressure seat 11, it is sufficient to control the operation of the adjustment motor 9. After the adjustment motor 9 is started, its output shaft rotates, and the telescopic rod 10 fixedly connected to the bottom end of the output shaft will drive the screw rod 8 to rotate. Under the action of the threaded hole 7, the screw rod 8 will move in the height direction, thereby changing the horizontal plane position of the lower pressure seat 11.

[0034] A support seat 12 is fixedly connected to the bottom end of the placement table 1 , and a plurality of reinforcement blocks 13 are fixedly connected between the hydraulic rod 4 and the upper surface of the cross plate 3 .

[0035] The support seat 12 plays a supporting role, and the plurality of reinforcement blocks 13 can improve the connection stability between the hydraulic rod 4 and the cross plate 3 .

[0036] The working principle of the automatic component injection mold tightening mechanism provided by the utility model is as follows:

[0037] When the diagonal support mechanism 6 in the device is actually used, the threaded sleeve 63 can be driven to move along its length direction by rotating the threaded rod 62. During the movement of the threaded sleeve 63, the lower connecting seat 64 at its outer end will drive the bottom end of the connecting rod 65 to move in the vertical direction. During its upward movement, it can drive the bottom end of the diagonal support rod 67 to expand outward, thereby adjusting the extension length of the diagonal support rod 67. When the device is actually used, the extension distance of multiple diagonal support mechanisms 6 can be adjusted according to the actual size of the mold. When pressing down, multiple pressure points can be created through the bottom ends of multiple diagonal support rods 67, thereby fully covering the mold and ensuring the quality of the final product.

[0038] Compared with the related art, the automatic component injection mold tightening mechanism provided by the utility model has the following beneficial effects:

[0039] The utility model provides an automated component injection mold tightening mechanism, which is provided with a plurality of diagonal support mechanisms 6. When the device is in use, a hydraulic rod 4 pushes a lower pressure column 5 downward to move, and simultaneously pushes a plurality of diagonal support mechanisms 6 to move downward. The diagonal support mechanisms 6 of the device can adjust their own inclination angles to adjust their own coverage range, so that the device can have multiple force points when tightening the mold and can cover the entire mold, thereby ensuring the quality of the injection molded product and improving production efficiency.
