Description

Technical Field

[0001] The utility model relates to the technical field of mold protection switches, in particular to a stable mold protection switch. Background Art

[0002] The mold protection switch is a detection device used to detect whether the mold is closed. The existing mold protection switch includes a fixed block, a detection sensor installed on the fixed block, and a magnet block installed on one side of the fixed plate. When in use, one side of the fixed block is adsorbed and fixed on the moving plate by the magnet block. When the detection sensor detects the ejector fixing plate, it indicates that the mold is closed and sends instructions to the machine. The disadvantage is that the fixed block is not fixed stably. When the mold protection switch is used, the fixed block will rotate, thereby causing the detection sensor to rotate, affecting the detection of the ejector fixing plate by the detection sensor, thereby affecting the use of the mold protection switch.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] The utility model embodiment provides a stable mold protection switch, such as Figure 1-2As shown, it includes a fixed block 1, on which a detection sensor 2 is installed, and the detection sensor 2 is an inductive proximity switch. The detection sensor 2 is electrically connected to the machine's mold opening and closing signal line. The detection sensor 2 detects the ejector fixing plate, indicating that the mold closing is completed and sends a command to the machine. A first magnet block 3 is installed on one side of the fixed block 1, and the first magnet block 3 is disc-shaped. A second magnet block 4 is installed on the side of the fixed block 1 adjacent to the first magnet block 3, and the second magnet block 4 is a rectangular parallelepiped. When in use, one side of the fixed block 1 is fixed to the moving mold plate through the first magnet block 3, and the side of the fixed block 1 adjacent to the first magnet block 3 can be fixed to the rear mold bottom plate through the second magnet block 4. Compared with the existing mold protection switch, it has good stability and can prevent the fixed block 1 from rotating when the mold protection switch is in use, thereby preventing the use of the mold protection switch from being affected.

[0018] It should be noted that the fixing block 1 is an L-shaped structure, and the first magnet block 3 and the second magnet block 4 are mounted on two outer sides of the fixing block 1 that are perpendicular to each other.

[0019] In this embodiment, a rectangular mounting column 5 is installed on the side of the fixed block 1 opposite to the first magnet block 3, and a square frame mounting frame 6 is slidably sleeved on the mounting column 5. The detection sensor 2 is installed on the outer wall of the mounting frame 6. The mounting frame 6 can slide on the mounting column 5, and the detection sensor 2 can move with the mounting frame 6, so that the position of the detection sensor 2 can be adjusted according to different molds, so it has a wide range of applications.

[0020] In this embodiment, the side wall of the mounting column 5 is provided with a strip slide groove 51 along its length direction, and both sides of the inner wall of the slide groove 51 are provided with a strip limit groove 52 along its length direction. A slider 7 is slidably provided inside the limit groove 52, and the slider 7 is fixedly connected to the mounting frame 6 by a first bolt 8. When the position of the detection sensor 2 is adjusted, the first bolt 8 is loosened. When the first bolt 8 is loosened, the mounting frame 6 is slid to adjust the position of the detection sensor 2. After the adjustment is completed, the slider 7 is fixedly connected to the mounting frame 6 by the first bolt 8, so that the position of the detection sensor 2 can be fixed.

[0022] It should be noted that a first mounting groove is provided on one side of the fixed block 1, and the first magnet block 3 is installed inside the first mounting groove by a second bolt 10. At the same time, the second bolt 10 installs the mounting column 5 on the side of the fixed block 1 opposite to the first magnet block 3. The above design can facilitate the disassembly and assembly between the fixed block 1 and the first magnet block 3 and the mounting column 5, and at the same time, the first magnet block 3 can be firmly installed on the fixed block 1. A second mounting groove is provided on the side of the fixed block 1 adjacent to the first magnet block 3, and the second magnet block 4 is installed inside the second mounting groove by a third bolt 11. The above design can facilitate the disassembly and assembly between the fixed block 1 and the second magnet block 4, and at the same time, the second magnet block 4 can be firmly installed on the fixed block 1.

[0023] Specific principle: Before use, adjust the position of the detection sensor 2 according to the type of mold. After the adjustment, fix one side of the fixed block 1 on the movable mold plate through the first magnet block 3, and fix the side of the fixed block 1 adjacent to the first magnet block 3 on the rear mold bottom plate through the second magnet block 4. The detection sensor 2 detects the ejector fixing plate, indicating that the mold closing is completed and sends instructions to the machine. Compared with the existing mold protection switch, it has better stability and can prevent the fixed block 1 from rotating when the mold protection switch is in use, thereby preventing the use of the mold protection switch from being affected.
