DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A quick mold-changing mold frame comprises a mother mold frame and a sub-mold frame, the sub-mold frame is slidably connected in the mother mold frame, the mother mold frame is composed of a first upper mold frame 1, a first lower mold frame 2 and a plurality of first connecting columns 3, the first connecting columns 3 are fixedly connected between the first upper mold frame 1 and the first lower mold frame 2, the sub-mold frame is composed of a second upper mold frame 4, a second lower mold frame 5 and a plurality of second connecting columns 6, the second connecting columns 6 are fixedly connected between the second upper mold frame 4 and the second lower mold frame 5, the second upper mold frame 4 is abutted against the bottom of the first upper mold frame 1, and the second lower mold frame 5 is abutted against the upper end of the first lower mold frame 2;

[0022] The upper end of the second upper mold frame 4 and the bottom of the second lower mold frame 5 are both provided with two guide rails 7. The bottom of the first upper mold frame 1 and the upper end of the first lower mold frame 2 are both fixedly connected with guide components extending into the corresponding guide rails 7. The guide components include a convex rail 8 fixedly connected to the upper end of the first lower mold frame 2. The convex rail 8 extends into the corresponding guide rail 7. The convex rail 8 cooperates with the guide rail 7 to guide and position the sub-mold frame so that the sub-mold frame can stably slide into the mother mold frame or move out of the mother mold frame. The upper end of the convex rail 8 is rollingly connected with a plurality of balls 9 that abut against the inner top of the guide rail 7. The rolling of the balls 9 can reduce the friction between the convex rail 8 and the guide rail 7, which is conducive to the sliding of the sub-mold frame into the mother mold frame.

[0023] The rear side wall of the mother mold frame is connected with a baffle 15 that abuts against the rear side wall of the sub-mold frame through an adjustment component. The adjustment component includes a guide slot 13 opened on the rear side wall of the first upper mold frame 1, and a guide slider 14 adapted thereto is slidably connected in the guide slot 13. The baffle 15 is fixedly connected to the bottom of the guide slider 14 and abuts against the rear side wall of the second upper mold frame 4 and the second lower mold frame 5. The guide slider 14 slides in the guide slot 13 to guide the baffle 15, so that the baffle 15 can only slide back and forth. The baffle 15 is in contact with the second upper mold frame 4 and the second lower mold frame 5. The rear side walls abut against each other, and the depth of the sub-mold frame sliding into the mother mold frame can be limited. The inner side wall of the guide slide groove 13 is rotatably connected with a threaded rod 16, and the threaded rod 16 threadably penetrates the guide slider 14 and extends to the outer side of the first upper mold frame 1. The end of the threaded rod 16 is fixedly connected with a rotating handle 17. Rotating the rotating handle 17 can rotate the threaded rod 16, and then the guide slider 14 can drive the baffle 15 to slide back and forth to adjust the position of the baffle 15 under the action of its thread meshing. The outer side wall of the rotating handle 17 is provided with anti-slip grooves, which is convenient for rotating the rotating handle 17;

[0024] The front side wall of the mother mold frame is connected to the front side wall of the child mold frame through two locking blocks 12. The front side walls of the first lower mold frame 2 and the second lower mold frame 5 are both provided with a first mounting groove 10, and the front side walls of the first upper mold frame 1 and the first lower mold frame 2 are both provided with a second mounting groove 11. The locking block 12 is slidably connected between the corresponding first mounting groove 10 and the second mounting groove 11. The locking block 12 is connected to the inner side wall of the second mounting groove 11 through a long screw 18. The locking block 12 is abutted against the inner side wall of the first mounting groove 10. The length of the second mounting groove 11 is relatively long, which can adapt to the child mold frame to slide back and forth to adjust the installation position. The inner side wall of the second mounting groove 11 is provided with a threaded hole compatible with the long screw 18, and the locking block 12 can be installed through the long screw 18. The locking block 12 and the baffle 15 work together to ensure the stability of the child mold frame installed in the mother mold frame.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] In the utility model, when the quick mold-changing mold frame is in use, when the mold of the sub-mold frame needs to be changed, the long screw 18 is taken out, and the locking block 12 can be taken out from the first installation groove 10 and the second installation groove 11, so that the sub-mold frame can slide back and forth in the mother mold frame, and the sub-mold frame can be taken out and replaced;

[0027] The rotating handle 17 drives the threaded rod 16 to rotate, and the guide slider 14 can slide forward and backward in the guide slot 13 under the action of the thread engagement, and the baffle 15 can be moved forward and backward to adjust the position, so as to adjust the depth of the sub-mold frame sliding into the mother mold frame to meet different usage requirements;

[0028] The convex rail 8 is extended to the corresponding guide rail 7 on the replaced sub-mold frame, so that the sub-mold frame can be moved into the mother mold frame. The provision of the ball 9 can reduce the friction between the convex rail 8 and the guide rail 7, which is conducive to installing the sub-mold frame in the mother mold frame. The guide rail 7 cooperates with the convex rail 8 to ensure that the mother mold frame will not be offset when the sub-mold frame is replaced, which is convenient for better and more accurate replacement of the sub-mold frame.

[0029] Push the sub-mold frame to make it abut against the baffle 15, place the locking block 12 in the corresponding first mounting groove 10 and the second mounting groove 11, and make the locking block 12 abut against the inner wall of the first mounting groove 10, fix the locking block 12 by the long screw 18, and complete the replacement of the sub-mold frame.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
