DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 2The utility model provides an embodiment: a quick mold changing tool for a plastic injection mold, comprising a main rod 1, the bottom of the main rod 1 is fixedly connected to a base 8, the outer wall of the main rod 1 is fixedly connected to a fixed ring 10, the outer wall of the fixed ring 10 is rotatably connected to a transmission rod 9, one side of the transmission rod 9 is rotatably connected to a connecting plate 3, the outer wall of the connecting plate 3 is fixedly connected to a rubber pad 2, the outer wall of the main rod 1 is slidably connected to a lifting ring 11, the outer wall of the lifting ring 11 is rotatably connected to a rotating rod 4, the upper surface of the lifting ring 11 is fixedly connected to a fixed shell 7, and a moving component is provided on the top of the main rod 1, which acts to move the main rod 1 device.

[0032] Specifically, due to the action of gravity, the fixed shell 7 begins to fall, and the fall of the fixed shell 7 drives the lifting ring 11 to fall together. The fall of the lifting ring 11 causes the rotating rod 4 to rotate, thereby driving the connecting plate 3 to move. At the same time, the movement of the connecting plate 3 drives the transmission rod 9 to rotate, so that the connecting plate 3 drives the fixed rubber pad 2 to move, so that it is close to the inner wall of the mold, so that the mold can be smoothly taken out, and stable support and protection can be provided to avoid damage to the mold during the removal and placement process. There is no need to laboriously carry the mold, which reduces labor intensity. The correct use of the internal support tooling can reduce the wear and damage of the mold and extend its service life. Therefore, the rapid replacement of the mold can adapt to the production needs of different products and improve the flexibility of production.

[0033] Reference Figure 1 The moving assembly includes a triangular handle 5, the lower surface of which is fixedly connected to the top of the main rod 1.

[0034] Specifically, the device and the fixed mold can be conveniently moved through the triangular handle 5, so that the operator can hold and operate the device more easily, reducing the difficulty and fatigue of the operation, and can hold the triangular handle 5 more stably, reducing the risk of the device accidentally slipping or losing control during movement, thereby ensuring the safety of the operator.

[0035] Reference Figure 1 and Figure 3, a card slot 6 is opened inside the main rod 1, a slide rail 16 is opened inside the fixed shell 7, a slide slot 22 is opened inside the fixed shell 7, a fixed column 19 is fixedly connected to the fixed shell 7, and the outer wall of the fixed column 19 is provided with a spring 20, one end of the spring 20 is fixedly connected to the inside of the slide rail 16, and the other end of the spring 20 is fixedly connected to the movable frame 13, the movable frame 13 is slidably connected to the inside of the slide rail 16, the outer wall of the movable frame 13 is fixedly connected to the pressing block 12, and a limiting groove 15 is opened inside the movable frame 13, and a limiting block 17 is provided on the outer wall of the limiting groove 15. The outer wall of the limiting block 17 is fixedly connected to the pulling column 14, and the outer wall of the pulling column 14 is provided with a spring 18, one end of the spring 18 is fixedly connected to the outer wall of the limiting block 17, and the other end of the spring 18 is fixedly connected to the inside of the fixed shell 7. The outer wall of the limiting block 17 is fixedly connected with a card column 21, and the outer wall of the card column 21 is slidably connected to the inside of the slide slot 22.

[0036] Specifically, pulling the pull post 14 causes the limiting block 17 to move and enter the limiting groove 15. Because the contact surfaces between the limiting block 17 and the limiting groove 15 are both inclined, the limiting block 17 pushes the movable frame 13 to move within the slide rail 16. Simultaneously, the movable frame 13 pulls on the fixed spring 20. When the limiting block 17 moves to the outer wall of the movable frame 13, the spring 20 rebounds and drives the movable frame 13 back to its original position. At this point, the contact surface is flat, securing the limiting block 17, thereby allowing the locking column 21 to slide out of the locking groove 6. When the limiting block 17 moves, the spring 18 will also be compressed. When used horizontally, the pressing block 12 can be pressed, and the moving frame 13 can be moved by the pressing block 12, so that the limiting groove 15 moves, and the limiting block 17 is driven back to its original position by the rebound of the spring 18, so that the clamping column 21 slides into the inside of the clamping groove 6 to achieve fixation. This can ensure that the internal support tooling remains stable in the mold and prevents movement or shaking during operation, thereby providing reliable support and reducing the risk of accidental falling off of the mold during removal or insertion, ensuring the safety of the operator. At the same time, stable locking helps to reduce operational errors caused by unstable tooling and improve product quality.

[0037] Working principle: Move the device to the inside of the mold through the triangular handle 5, then pull the pulling column 14, and drive the limiting block 17 to move into the limiting groove 15 through the pulling column 14. Since the contact surfaces of the limiting block 17 and the limiting groove 15 are both inclined surfaces, the movable frame 13 is pushed to move inside the slide rail 16 through the limiting block 17, and the fixed spring 20 is pulled by the movable frame 13. When the limiting block 17 moves to the outer wall of the movable frame 13, the spring 20 rebounds and drives the movable frame 13 back to its original position. At this time, the contact surface is flat, and the limiting block 17 can be fixed, so that the card column 21 slides out from the inside of the card slot 6, and the spring 1 18 is compressed while the limiting block 17 moves, thereby Gravity drives the fixed shell 7 to fall, and then drives the lifting ring 11 to descend through the fixed shell 7, and then drives the rotating rod 4 to rotate through the lifting ring 11, drives the connecting plate 3 to move, and at the same time drives the transmission rod 9 to rotate through the connecting plate 3, thereby driving the fixed rubber pad 2 to move through the connecting plate 3, close to the inner wall of the mold to take out the mold. When gravity cannot be used to take out the horizontal mold, the pressing block 12 can be pressed, and the pressing block 12 drives the moving frame 13 to move, so that the limiting groove 15 moves, and the limiting block 17 is driven back to its original position by the rebound of the spring 18, so that the card column 21 slides into the inside of the card slot 6 for fixation, and then the mold is taken out through the triangular handle 5.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
