Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0035] In some embodiments, please refer to the attached drawings of the specification Figures 1-6 A device capable of quickly replacing injection molds of different specifications, including a base 10;

[0036] The upper end of the base 10 is fixedly installed with a lower bottom plate 20;

[0037] The upper side of the lower bottom plate 20 is fixedly installed with an upper bottom plate 30;

[0038] A rotating platform 40 is installed on the upper side of the upper bottom plate 30, and a rotating mechanism 80 is installed between the lower bottom plate 20 and the upper bottom plate 30;

[0039] The interior of the rotating platform 40 is evenly divided into two mold bearing areas 110 on both sides by a baffle fixedly arranged in the middle of the rotating platform 40;

[0040] Side plates 50 for preventing the mold from falling are fixedly installed on the outside of the mold bearing area 110. A synchronous limiting mechanism 90 is arranged between the two mold bearing areas 110, and the synchronous limiting mechanism 90 is connected to the rotating platform 40; Roller supports 60 for carrying the mold are evenly and rotatably installed at equal intervals between the side plates 50 and the synchronous limiting mechanism 90. Material transfer openings for feeding and discharging are formed in the mold bearing area 110, and the material transfer openings of the two mold bearing areas 110 are staggered. A connection platform 70 for connecting the injection molding machine is provided at the material transfer opening of each mold bearing area 110;

[0041] The connection platform 70 includes a connecting plate 120, roller supports 60 and a self-locking mechanism 100. The connecting plate 120 is rotatably connected to the side plate 50 at the discharge port of the mold bearing area 110. Roller supports 60 are evenly and rotatably installed at equal intervals between the connecting plates 120. A self-locking mechanism 100 is installed at one end of the connecting plate 120 away from the rotating platform 40.

[0042] In the present utility model, two sets of molds with different specifications are synchronously limited by the synchronous limiting mechanism 90 and the side plate 50. A mold to be replaced is placed on one mold bearing area 110. The device is moved to the injection molding machine and the other mold bearing area 110 is aligned with the mold to be replaced. The connecting plate 120 is rotated until the rollers 60 of the connecting plate 120 are flush with the rollers 60 of the rotating platform 40. The device is locked and connected to the injection molding machine through the self-locking mechanism 100. The mold to be replaced is moved into the other mold bearing area 110 through the rollers 60. The locking of the self-locking mechanism 100 is released and the connecting plate 120 is rotated back to its original position. The rotating mechanism 80 drives the entire rotating platform 40 to rotate 180 degrees, so that one mold bearing area 110 automatically aligns with the injection molding machine. The device is locked and connected to the injection molding machine through the self-locking mechanism 100, and the mold to be replaced is moved into the injection molding machine through the rollers 60 to complete the replacement.

[0043] In the present utility model, the locking connection with the injection molding machine is completed through the self-locking mechanism 100, so that the entire connection platform 70 will not be separated from the injection molding machine during the mold replacement. The two sets of molds with different specifications are limited by the synchronous limiting mechanism 90 and the side plate 50. The rotating mechanism 80 rotates 180 degrees, so that the mold to be replaced is automatically aligned with the inside of the injection molding machine, and there is no need to align the mold to be replaced with the injection molding machine again, realizing the rapid replacement of the injection mold.

[0044] The rotating mechanism 80 includes a push cylinder 81, a hinge seat 82, a connecting rod 83, a driving gear 84, a driven gear 85 and a rotating rod 86. The housing of the push cylinder 81 is hinged to the lower bottom plate 20 through the hinge seat. Both the driving gear 84 and the driven gear 85 are rotatably installed on the upper side of the lower bottom plate 20. The output end of the push cylinder 81 is hinged to the connecting rod 83 through the hinge seat 82. The connecting rod 83 is fixedly connected to the driving gear 84. The driving gear 84 is meshed with the driven gear 85. Both ends of the rotating rod 86 are fixedly connected to the driven gear 85 and the rotating platform 40 respectively.

[0045] In the present utility model, by starting the push cylinder 81 to push the hinge seat 82 to move, the movement of the hinge seat 82 drives the driving gear 84 to rotate, thereby driving the entire rotating platform 40 to rotate. Through the cooperation of the rotating rod 86 and the driven gear 85, the entire rotating platform 40 rotates 180 degrees, realizing the transposition of the mold to be replaced and the mold to be replaced, and accelerating the speed of mold replacement.

[0046] The synchronous limiting mechanism 90 includes a limiting plate 91, a connecting rod 92, a movable block 93, a screw rod 94, a handle 95 and a slider 96; the screw rod 94 is rotatably installed on the upper side of the rotating platform 40, and a handle 95 for rotating the screw rod 94 is fixedly installed on the top of the screw rod 94. The slider 96 is threadedly connected to the screw rod 94 through a threaded sleeve, and the connecting rod 92 is symmetrically arranged with respect to the slider 96. The two ends of the connecting rod 92 are respectively hinged to the slider 96 and the limiting plate 91 through a hinge seat.

[0047] In the present invention, the screw rod 94 is rotated by rotating the second handle 95, the screw rod 94 rotates to drive the slider 96 to move, and the slider 96 moves to drive the second connecting rod 92 to rotate, thereby driving the limit plates 91 at both ends to synchronously move away from or close to the screw rod 94. Through the synchronous movement of the limit plates 91 at both ends, two groups of injection molds of different specifications are synchronously pushed toward the side plates 50, and the limit plates 91 and the side plates 50 cooperate to limit the molds of different specifications, so that the molds keep their positions unchanged when the rotating platform 40 rotates, so that the rotating platform 40 can automatically align the molds used for replacement with the injection molding machine after rotation, and no secondary alignment is required, which speeds up the replacement of the injection mold.

[0048] The self-locking mechanism 100 includes a locking groove 101, a locking block 102, a handle 103 and a locking groove 2 104; a locking groove 101 for overlapping the roller of the injection molding machine is provided at one end of the connecting plate 120 away from the rotating platform 40, and the locking block 102 is rotatably connected to the end of the connecting plate 120 away from the rotating platform 40, and the locking block 102 is in a barb shape as a whole, and the locking block 102 is fixedly connected to the handle 1 103, and a locking groove 2 104 for locking the roller of the injection molding machine is provided on the locking block 102; the rotating connecting plate 120 is connected to the roller of the injection molding machine through the locking groove 101;

[0049] In the utility model, the locking block 102 rotates under the action of gravity, so that the roller of the injection molding machine is locked in the locking block 102, and the locking block 102 is driven to rotate as a whole by manually turning the handle 103 to achieve unlocking; the injection molding machine roller is locked in the locking groove 104 through the cooperation of the locking block 102, the locking groove 104 and the locking groove 101, so that the connecting platform 70 as a whole will not be separated from the injection molding machine during the mold replacement process.
