[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-7 A quick-change device for injection molds includes a lower mold frame 1 and an upper mold frame 2. The upper mold frame 2 is provided on the top of the lower mold frame 1. Vertical light rods 3 are fixed at the four corners of the bottom of the upper mold frame 2. The vertical light rods 3 pass through the interior of the lower mold frame 1 and are slidably connected to the lower mold frame 1. A detachable and replaceable mold 4 is provided inside both the lower mold frame 1 and the upper mold frame 2. Multiple rectangular limiting blocks 9 are slidably connected inside both the lower mold frame 1 and the upper mold frame 2. A moving mechanism for moving the rectangular limiting blocks 9 is provided inside both the lower mold frame 1 and the upper mold frame 2.

[0025] Both the lower mold holder 1 and the upper mold holder 2 are provided with limiting mechanisms on their outer sides to restrict the movement of the rectangular limiting block 9;

[0026] Both the lower mold holder 1 and the upper mold holder 2 are provided with rectangular sliding grooves. The rectangular limiting block 9 is located inside the rectangular sliding groove and is slidably connected to the lower mold holder 1 or the upper mold holder 2 through the rectangular sliding groove. The rectangular sliding groove allows the rectangular limiting block 9 to slide inside the lower mold holder 1 or the upper mold holder 2.

[0027] The top of the rectangular limiting block 9 has an inclined surface, and the interior of the replaceable mold 4 has a rectangular limiting groove that is adapted to the rectangular limiting block 9. The replaceable mold 4 and the rectangular limiting block 9 are slidably connected through the rectangular limiting groove. With the setting of the inclined surface, when the replaceable mold 4 descends to the surface of the rectangular limiting block 9, the rectangular limiting block 9 can move inside the lower mold frame 1 or the upper mold frame 2. And when the rectangular limiting block 9 enters the interior of the replaceable mold 4, it can restrict the movement of the replaceable mold 4 inside the lower mold frame 1 or the upper mold frame 2.

[0028] The moving mechanism includes two transverse connecting blocks 7. Transverse connecting blocks 7 are provided on both sides inside the lower mold frame 1. Both ends of the transverse connecting blocks 7 are rotatably connected to inclined rotating columns 8 by pins. The two inclined rotating columns 8 at the same end are rotatably connected to a longitudinal connecting column 13 by pins. A transverse smooth rod 11 is slidably connected inside the longitudinal connecting column 13. The transverse smooth rod 11 is located inside the lower mold frame 1 and is fixedly connected to the lower mold frame 1. A longitudinal connecting column 13 is provided between the two longitudinal connecting columns 13 and outside the transverse smooth rod 11. A longitudinal support column 10 is fixedly connected to the top of the longitudinal connecting column 13. The top of the longitudinal support column 10 is fixedly connected to a rectangular limiting block 9.

[0029] The longitudinal connecting column 13 has a circular through hole inside. The transverse light rod 11 is located inside the circular through hole and is slidably connected to the longitudinal connecting column 13 through the circular through hole. The circular through hole allows the longitudinal connecting column 13 to slide laterally on the outside of the transverse light rod 11. The movement of the two longitudinal connecting columns 13 causes the first transverse rigid spring 12 to be compressed by force.

[0030] A longitudinal light rod 6 is fixed to the outside of the transverse connecting block 7. A circular push block 5 is fixed to the side of the longitudinal light rod 6 away from the transverse connecting block 7. The longitudinal light rod 6 passes through the interior of the lower mold frame 1 and is slidably connected to the lower mold frame 1, so that the longitudinal light rod 6 can slide inside the lower mold frame 1. By pushing the circular push block 5, the longitudinal light rod 6 can slide inside the lower mold frame 1. The movement of the longitudinal light rod 6 allows the transverse connecting block 7 to move.

[0031] Here, the circular push block 5 is pushed so that the longitudinal light rod 6 can slide inside the lower mold frame 1. The sliding of the longitudinal light rod 6 allows the transverse connecting block 7 to move. The movement of the transverse connecting block 7 causes the two longitudinal connecting columns 13 to slide outside the transverse light rod 11 through the oblique rotating column 8. The movement of the two longitudinal connecting columns 13 causes the first transverse rigid spring 12 to be deformed by force. The movement of the two longitudinal connecting columns 13 allows the longitudinal support column 10 to move inside the lower mold frame 1. The movement of the longitudinal support column 10 allows the rectangular limiting block 9 to move. When the rectangular limiting block 9 moves out of the interior of the replaceable mold 4, the restriction of the rectangular limiting block 9 on the replaceable mold 4 is released, so that the replaceable mold 4 can be disassembled.

[0032] The limiting mechanism includes an arc-shaped fixing plate 14. An arc-shaped fixing plate 14 is fixed on the outside of the lower mold frame 1. A transverse limiting rod 15 is slidably connected inside the arc-shaped fixing plate 14. A circular pull block 16 is fixed at one end of the transverse limiting rod 15. A second transverse rigid spring 17 is provided between the circular pull block 16 and the arc-shaped fixing plate 14 and on the outside of the transverse limiting rod 15.

[0033] The longitudinal light rod 6 has a circular limiting hole that matches the transverse limiting rod 15. The circular limiting hole allows the transverse limiting rod 15 to slide inside the longitudinal light rod 6. When the transverse limiting rod 15 moves out of the longitudinal light rod 6, the longitudinal light rod 6 can slide inside the lower mold frame 1.

[0034] Here, by pulling the circular pull block 16, the transverse limiting rod 15 can slide inside the arc-shaped fixing plate 14. The sliding of the arc-shaped fixing plate 14 causes the second transverse rigid spring 17 to be stretched. When the transverse limiting rod 15 moves out of the interior of the longitudinal light rod 6, the longitudinal light rod 6 can slide inside the lower mold frame 1, thereby releasing the restriction of the transverse limiting rod 15 on the longitudinal light rod 6.

[0035] Working principle: Pushing the circular push block 5 allows the longitudinal light rod 6 to slide inside the lower mold frame 1. The sliding of the longitudinal light rod 6 allows the transverse connecting block 7 to move. The movement of the transverse connecting block 7 causes the two longitudinal connecting columns 13 to slide outside the transverse light rod 11 through the oblique rotating column 8. The movement of the two longitudinal connecting columns 13 causes the first transverse rigid spring 12 to deform under force. The movement of the two longitudinal connecting columns 13 allows the longitudinal support column 10 to move inside the lower mold frame 1. The movement of the longitudinal support column 10 allows the rectangular limiting block 9 to move. When the rectangular limiting block 9 moves out of the interior of the replaceable mold 4, the restriction of the rectangular limiting block 9 on the replaceable mold 4 is released, allowing the replaceable mold 4 to be disassembled.

[0036] By pulling the circular pull block 16, the transverse limiting rod 15 can slide inside the arc-shaped fixed plate 14. The sliding of the arc-shaped fixed plate 14 causes the second transverse rigid spring 17 to be stretched. When the transverse limiting rod 15 moves out of the interior of the longitudinal light rod 6, the longitudinal light rod 6 can slide inside the lower mold frame 1, thereby releasing the restriction of the transverse limiting rod 15 on the longitudinal light rod 6.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
