Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to a limiting structure for injection molds. Background Technology
[0002] The limiting structure in injection molds is mainly used to control the opening and closing stroke of the mold, ensure proper mold closing, and prevent over-opening or incomplete mold closing, thereby ensuring the smooth progress of the injection molding process. The limiting structure is a very important part of injection mold design, helping the mold reach a predetermined range of motion during operation.
[0003] Without such limiting devices, the opening and closing stroke of the mold may be uncontrolled when using traditional equipment, leading to excessive opening or closing of the mold or incomplete mold closing, causing instability in the production process.
[0004] Secondly, without limit rods and measuring rods, the distance between mold opening and closing may be difficult to control precisely, resulting in poor repeatability of mold operation and unstable production process.
[0005] Finally, without a locking mechanism, the various components of the mold may loosen or shift due to vibration or external forces generated during use, affecting the accuracy and stability of the mold and potentially leading to a decrease in production efficiency. Summary of the Invention

[0020] 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.
[0021] Example 1: Please see Figures 1-5A limiting structure for an injection mold includes a main body 1, an installation mechanism, a measuring mechanism, and a locking mechanism. The installation mechanism includes an installation component 2 and a positioning component 3. The installation component 2 is installed on the main body 1 and is connected to the main body 1. The positioning component 3 is installed on the installation component 2 and is slidably connected to the installation component 2 and connected to the main body 1. A movable mold 4 is installed on the main body 1. The measuring mechanism includes a limiting rod 5 and a connecting component 6. The limiting rod 5 is installed on the movable mold 4 and is connected to the movable mold 4. The connecting component 6 is installed on the limiting rod 5 and is connected to the limiting rod 5. A measuring rod 7 is installed on the connecting component 6 and is slidably connected to the connecting component 6 and connected to the positioning component 3.
[0022] In this embodiment, the installation mechanism includes an installation component 2 and a positioning component 3. In use, the installation component 2 can be installed on the guide rod 11 of the main body 1. The first screw 14 on the installation component 2 is connected to the first threaded hole 12 of the guide rod 11. During installation, the positioning component 3 is pulled so that it can slide on the installation component 2 and directly stretch the first spring 10. After the installation component 2 is installed, the positioning component 3 is released so that it is connected to the positioning hole 13, thereby fixing the installation component 2 on the guide rod 11.
[0023] In this embodiment, the measuring mechanism includes a limiting rod 5 and a connecting member 6. In use, when installing the mounting member 2 on the guide rod 11, the limiting rod 5 can be installed on the second threaded hole 17 of the movable mold 4 first, so that the second screw 15 on the limiting rod 5 is connected with the second threaded hole 17. Then, the movable mold 4 can be pushed to slide on the guide rod 11, so that one end of the guide rod 11 protrudes. Then, the mounting member 2 can be installed. After the limiting rod 5 is installed, the connecting member 6 can be installed on the limiting rod 5. When installing the connecting member 6, the measuring rod 7 is pulled, so that the measuring rod 7 can slide on the connecting member 6 and directly compress the second spring 21. After the connecting member 6 is connected, the measuring rod 7 can be released, so that the square hole 20 on the measuring rod 7 is connected with the square rod 19 on the positioning member 3, so that the position of the positioning member 3 is fixed.
[0024] In this embodiment, the locking mechanism includes a rotating member 8 and a locking rod 9. In use, the internal hexagon can be directly driven to rotate the fitting hole 24 on the rotating member 8, so that the rotation of the rotating member 8 can be directly wound around the connecting rope 23, and the locking rod 9 can slide in the movable mold 4 and directly compress the third spring 22. After the limiting rod 5 is installed, the rotating member 8 is released, so that the locking rod 9 is engaged with the locking hole 16 on the limiting rod 5, thereby fixing the position of the limiting rod 5.
[0025] Example 2: In summary, during use, the mounting part 2 and the positioning part 3 can be installed on the main body 1 first. The mounting part 2 is then installed on the guide rod 11. The first screw 14 on the mounting part 2 is connected to the first threaded hole 12 of the guide rod 11. During installation, the positioning part 3 is pulled, allowing it to slide on the mounting part 2 and directly stretch the first spring 10. After the mounting part 2 is installed, the positioning part 3 is released, allowing it to connect with the positioning hole 13, thereby fixing the mounting part 2 to the guide rod 11. However, when installing mounting part 2, the limiting rod 5 should be installed on the movable mold 4 in advance. At this time, the internal hexagon can be directly driven to rotate the fitting hole 24 on the rotating part 8, so that the rotation of the rotating part 8 can be connected to the connecting rope 23, so that the locking rod 9 can slide in the movable mold 4 and directly compress the third spring 22. After the limiting rod 5 is installed, the rotating part 8 is released, so that the locking rod 9 and the locking hole 16 on the limiting rod 5 are engaged and connected, thereby fixing the position of the limiting rod 5, and moving towards the second threaded hole 1 of the movable mold 4. Install the upper limit rod 5 on the limit rod 7, so that the second screw 15 on the limit rod 5 is connected to the second threaded hole 17. Then, the movable mold 4 can be pushed to slide on the guide rod 11, so that one end of the guide rod 11 protrudes. Then, the mounting part 2 can be installed. After the limit rod 5 is installed, the connecting part 6 can be installed on the limit rod 5. When installing the connecting part 6, pull the measuring rod 7 so that the measuring rod 7 can slide on the connecting part 6 and directly compress the second spring 21. After the connecting part 6 is connected, the measuring rod 7 can be released. This allows the square hole 20 on the measuring rod 7 to connect with the square rod 19 on the positioning part 3, thus fixing the position of the positioning part 3. When the device is assembled and in operation, the sliding of the movable mold 4 causes the guide rod 11 to move relative to the movable mold 4 and the limiting rod 5. The measuring rod 7 moves relative to the limiting rod 5. When different injection molds require different position distances, the mounting parts 2 of different thicknesses can be installed on the guide rod 11 by observing the value of the measuring rod 7, which facilitates the diversified use of small injection molds.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
