[0001] This utility model relates to the field of lifebuoy shell mold technology, specifically a detachable lifebuoy shell forming mold. Background Technology

[0002] A life ring is a type of water rescue equipment, usually made of cork, foam plastic or other lightweight materials with a low specific gravity, and covered with canvas, plastic, etc. Life rings used for swimming practice can also be made of rubber and filled with air, and are also called rubber rings.

[0003] Life rings are divided into inflatable life rings and plastic life rings. Plastic life rings are those with a plastic outer shell and are filled with polyurethane foam or gas, which provides buoyancy. These life rings are more durable. In the production of plastic life rings, molding molds are required to shape the outer shell.

[0004] However, the cores used in existing molds for producing lifebuoy shells are all integral structures. When processing lifebuoys of different sizes, the entire mold template needs to be replaced, which is time-consuming and labor-intensive. Therefore, it does not meet the current needs. To address this, we propose a detachable lifebuoy shell forming mold. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable life ring shell molding mold to solve the problems mentioned in the background art, where the core used in the mold for producing life ring shells is an integral structure, and when processing life rings of different sizes, the mold template needs to be replaced as a whole, which is time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable life ring shell molding mold, comprising a mold frame, a movable template slidably mounted on the inner side of the mold frame, a fixed template below the movable template, a pad mounted on the bottom of the fixed template and fixed to the mold frame by the pad, a hydraulic rod installed between the movable template and the mold frame, the top end of the hydraulic rod being fixed to the mold frame, and the bottom end of the hydraulic rod being fixed to the upper surface of the movable template, a plurality of fixed mold cores detachably mounted on the upper surface of the fixed template, a plurality of movable mold cores detachably mounted on the bottom surface of the movable template, the fixed mold cores being arranged in a circular array around the axis of the fixed template, and the movable mold cores being arranged in a circular array around the axis of the movable template.

[0007] Preferably, a positioning plug rod is fixed to the bottom end of the fixed model core and the upper surface of the moving model core, and an anti-detachment support block is fixed to the outer surface of the positioning plug rod.

[0008] Preferably, a rotating rod is inserted through the interior of both the fixed template and the moving template. One end face of the rotating rod is flush with the top surface of the fixed template and the lower surface of the moving template. Multiple rotating support plates are installed in a circular array on the outer surface of the other end of the rotating rod. A rotating locking block is fixed to the end of the rotating support plate away from the rotating rod. The anti-detachment support block is locked inside the rotating locking block.

[0009] Preferably, one end of the positioning plug rod is provided with a round hole, and an ejector spring is installed in the round hole. The ejector spring is in a compressed state and one end of the ejector spring is fixed to the fixed template or the moving template. The other end of the ejector spring is not fixedly connected to the positioning plug rod.

[0010] Preferably, the bottom surface of the fixed template and the upper surface of the moving template are both detachably mounted with detachable limiting plates by screws, and one end of the rotating rod is inserted into the detachable limiting plate and connected to the detachable limiting plate by a ball bearing.

[0011] Preferably, the outer surface of the end of the rotating rod that is inserted into the detachable limiting plate is provided with a plurality of insertion slots arranged in a circular array around its axis, and the end of the rotating support plate that contacts the rotating rod is fixed with an insertion block, which is inserted into the inner side of the insertion slot.

[0012] Preferably, the rotating snap-fit ​​block is attached to the fixed template, the moving template and the detachable limiting plate. The rotating snap-fit ​​block moves in a circular motion around the axis of the rotating rod between the detachable limiting plate and the fixed template and the moving template. The end of the rotating rod that is flush with the fixed template and the moving template is provided with a hexagonal hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model divides the core used for molding the lifebuoy shell into multiple fixed mold cores and moving mold cores, and the fixed mold cores and moving mold cores are distributed in a circular array around the axis of the fixed template and moving template. At the same time, the fixed mold cores and moving mold cores are connected to the fixed template and moving mold cores through positioning plug-in rods, anti-detachment support blocks and rotating snap-fit ​​blocks, so as to obtain a modular and detachable lifebuoy shell molding mold. This facilitates the quick replacement of fixed mold cores and moving mold cores of different specifications, and improves the production efficiency and flexibility of lifebuoy shells of different sizes.

[0015] 2. This utility model involves disassembling and removing the fixed template and the moving template, then using a hex wrench to rotate the rotating rod. This causes the rotating rod to rotate the rotating support plate and the rotating locking block, resulting in misalignment between the rotating locking block and the anti-detachment support block. At this point, the anti-detachment support block loses its restraint and the ejector spring elastically returns to its original position. The ejector spring lifts the positioning plug rod, the fixed model core, and the moving model core, allowing the operator to remove and replace the fixed model core and the moving model core. This reduces the difficulty of replacing the fixed model core and the moving model core, shortens the removal time, and improves the efficiency of replacing the fixed model core and the moving model core.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1As shown, a detachable lifebuoy shell molding mold has a movable template 4 slidably installed on the inner side of the mold frame 1. A fixed template 3 is provided below the movable template 4. A pad is installed at the bottom of the fixed template 3 and fixed to the mold frame 1 through the pad. A hydraulic rod 2 is installed between the movable template 4 and the mold frame 1. The top end of the hydraulic rod 2 is fixed to the mold frame 1, and the bottom end of the hydraulic rod 2 is fixed to the upper surface of the movable template 4. Multiple fixed mold cores 6 are detachably installed on the upper surface of the fixed template 3, and multiple movable mold cores 7 are detachably installed on the bottom surface of the movable template 4. The fixed mold cores 6 are arranged in a circular array around the axis of the fixed template 3, and the movable mold cores 7 are arranged in a circular array around the axis of the movable template 4. The movable template 4 is driven to move up and down by the hydraulic rod 2 to realize the closing or opening of the movable template 4 and the fixed template 3. After the fixed template 3 and the movable template 4 are closed, a molding cavity is formed by the fixed mold cores 6 and the movable mold cores 7 to form the lifebuoy shell.

[0023] like Figures 2 to 4 As shown, positioning insertion rods 12 are fixed to the bottom of the fixed model core 6 and the upper surface of the moving model core 7. Anti-detachment support blocks 14 are fixed to the outer surface of the positioning insertion rods 12. Rotating rods 8 are inserted through the interior of the fixed template 3 and the moving template 4. One end face of the rotating rod 8 is flush with the top surface of the fixed template 3 and the lower surface of the moving template 4. Multiple rotating support plates 11 are installed in a circular array on the outer surface of the other end of the rotating rod 8. A rotating snap block 15 is fixed to the end of the rotating support plate 11 away from the rotating rod 8. The anti-detachment support block 14 is snapped into the inner side of the rotating snap block 15. The rotating snap block 15 at the end of the rotating support plate 11 is used to snap and limit the anti-detachment support block 14, ensuring that the positioning insertion rods 12 on the bottom surface of the fixed model core 6 and the top surface of the moving model core 7 cannot be separated from the fixed template 3 and the moving template 4, thus ensuring the structural stability of the fixed model core 6 and the moving model core 7 after installation.

[0024] One end of the positioning plug-in rod 12 is provided with a round hole, in which an ejector spring 13 is installed. The ejector spring 13 is in a compressed state and one end of the ejector spring 13 is fixed to the fixed template 3 or the moving template 4. The other end of the ejector spring 13 is not fixedly connected to the positioning plug-in rod 12. When the anti-detachment support block 14 on the outer surface of the positioning plug-in rod 12 loses the restriction of the rotation locking block 15, the ejector spring 13 elastically returns to its original state and lifts the positioning plug-in rod 12, so that the fixed model core 6 and the moving model core 7 pop out from the fixed template 3 and the moving template 4, making it convenient for the staff to replace the fixed model core 6 and the moving model core 7.

[0025] The bottom surface of the fixed template 3 and the upper surface of the movable template 4 are both detachably mounted with removable limiting plates 5 by screws. One end of the rotating rod 8 is inserted into the removable limiting plate 5 and connected to it via a ball bearing. The outer surface of the end of the rotating rod 8 inserted into the removable limiting plate 5 has multiple insertion slots 9 arranged in a circular array around its axis. The end of the rotating support plate 11 that contacts the rotating rod 8 is fixed with an insertion block 10, which is inserted into the inner side of the insertion slot 9. The rotating locking block 15 is connected to the fixed template 3. The movable template 4 and the detachable limiting plate 5 are attached together. The rotating locking block 15 moves in a circle around the axis of the rotating rod 8 between the detachable limiting plate 5 and the fixed template 3 and the movable template 4. The end of the rotating rod 8 that is flush with the fixed template 3 and the movable template 4 is provided with a hexagonal hole. When the rotating rod 8 is rotated by a hexagonal wrench, the rotating rod 8 drives the plug-in block 10 to rotate, causing the rotating support plate 11 and the rotating locking block 15 to rotate simultaneously with the rotating rod 8, thereby realizing the separation or docking of the rotating locking block 15 and the anti-detachment support block 14.

[0026] Working Principle: When forming the lifebuoy shell using a mold, the fixed mold core 6 and moving mold core 7 are first selected according to the size of the lifebuoy shell. After selecting the appropriate mold cores 6 and 7, the fixed template 3 and moving template 4 are placed on the ground. Then, the fixed mold cores 6 and 7 are installed into the fixed template 3 and moving template 4, ensuring that the positioning insertion rod 12 of the fixed mold cores 6 and 7 covers the ejection spring 13 fixed in the fixed template 3 and moving template 4, compressing all the fixed mold cores 6 and 7 into the fixed template 3 and moving template 4. When the fixed mold cores 6 and 7 are compressed and flush with the surface of the fixed template 3 and moving template 4, a hex wrench is used to rotate the rotating rod 8. This causes the rotating rod 8 to drive the rotating support plate 11 and the rotating locking block 15 to rotate simultaneously through the insertion block 10. After the rotating locking block 15 rotates, it engages the anti-detachment support block 14 on the outer surface of the positioning insertion rod 12. When the locking mechanism is in place, the positioning plug-in rod 12 and the anti-detachment support block 14 are restricted by the rotating locking block 15 and cannot move. After the installation of the fixed mold core 6 and the moving mold core 7 is completed, the fixed template 3 and the moving template 4 are assembled with the mold frame 1 to form the lifebuoy shell. When the fixed mold core 6 and the moving mold core 7 need to be replaced, simply remove the fixed template 3 and the moving template 4, and then use a hex wrench to rotate the rotating rod 8. This will cause the rotating rod 8 to rotate the rotating support plate 11 and the rotating locking block 15, causing the rotating locking block 15 to be misaligned with the anti-detachment support block 14. At this time, the anti-detachment support block 14 is no longer restricted and the ejector spring 13 elastically returns to its original state. The ejector spring 13 lifts the positioning plug-in rod 12, the fixed mold core 6, and the moving mold core 7, allowing the staff to remove and replace the fixed mold core 6 and the moving mold core 7. This reduces the difficulty of replacing the fixed mold core 6 and the moving mold core 7, shortens the removal time, and improves the replacement efficiency of the fixed mold core 6 and the moving mold core 7.
