Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, specifically a sealing ring injection mold. Background Technology

[0002] Injection molds for sealing rings are specialized molds used to produce sealing rings, which are ring-shaped parts used for sealing and are widely used in automobiles, machinery, electronics, home appliances, medical fields, etc., to prevent the leakage of liquids or gases. An injection mold consists of two halves: a moving mold (moving half) and a fixed mold (fixed half). The shape and characteristics of the sealing ring are determined by the fit between these two mold halves. However, traditional injection molds for sealing rings make it inconvenient to remove the sealing ring from the mold after molding, which disrupts the continuity of sealing ring production and reduces production efficiency.

[0003] To address the aforementioned issues, the utility model patent with authorization announcement number CN222681618U discloses a sealing ring injection mold. This device uses a lifting plate to drive the sliding column upward, which in turn drives the molding ring to move upward relative to the mold core, ejecting the molded sealing ring from the mold. This facilitates the demolding of the sealing ring and improves the efficiency of sealing ring production.

[0004] However, in practical use, the device is inconvenient to replace the mold base, thus making it impossible to perform injection molding of sealing rings of different specifications, which narrows the scope of application of the device. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Example: Please refer to Figures 1-5 A sealing ring injection mold includes: a base 1, an mounting bracket 11 fixed to the upper end of the base 1, a lower mold base 14 inserted into the middle of the mounting bracket 11, an injection frame 12 fixed to the upper end of the mounting bracket 11, a lifting mechanism 2 mounted on the injection frame 12, and an upper mold base 13 detachably mounted to the lower end of the lifting mechanism 2; a fixing mechanism 4, disposed on the mounting bracket 11, for fixing the lower mold base 14 to the mounting bracket 11; and a connecting assembly, disposed between the lifting seat plate 23 of the lifting mechanism 2 and the upper mold base 13, for fixing the upper mold base 13 to the lifting seat plate 23.

[0018] The working principle of this utility model is as follows: the upper mold base 13 is fixed by setting a connecting component, and the lower mold base 14 is fixed by a fixing mechanism 4, which facilitates disassembly and assembly. It is convenient to install the upper mold base 13 and the lower mold base 14 of the required size according to actual needs, which can effectively expand the application range of the device and thus meet the processing needs of sealing rings of different specifications.

[0019] As a further solution, the mounting bracket 11 is provided with a pair of fixing slots 15, and the fixing mechanism 4 includes a fixing block 43 that is slidably installed in the fixing slot 15. A fixing telescopic rod 41 is provided between the fixing slot 15 and the fixing block 43. A fixing spring 42 is fitted on the fixing telescopic rod 41, and the two ends of the fixing spring 42 abut against the corresponding side of the fixing slot 15 and the fixing block 43, respectively.

[0020] The working principle of the fixing mechanism 4 is as follows: When fixing, push the fixing blocks 43 on both sides away from each other. At this time, the fixing telescopic rod 41 retracts and the fixing spring 42 is compressed. Then, the lower mold base 14 can be inserted into the mounting bracket 11. Then, release the fixing blocks 43. At this time, the fixing spring 42 returns to its original state and pushes the fixing blocks 43 to reset, thereby pressing the lower mold base 14 and completing the fixing work. The operation is simple, and it is convenient to disassemble and assemble. It is easy to replace the lower mold base 14 of different specifications, thereby facilitating the processing of sealing rings of different specifications.

[0021] As a further embodiment, the lower end of the lifting seat plate 23 is provided with a T-shaped connecting slot, and the connecting assembly includes a connecting plug 133 at the upper end of the upper mold base 13. The connecting plug 133 is inserted into the connecting slot, and a connecting bolt 134 is threadedly screwed onto the upper end of the lifting seat plate 23. The lower end of the connecting bolt 134 abuts against the upper end of the connecting plug 133.

[0022] The working principle of the connecting component is as follows: When connecting, insert the connecting plug 133 into the connecting slot, and then rotate the connecting bolt 134 so that the lower end of the connecting bolt 134 abuts against the upper end of the connecting plug 133, which can prevent the connecting plug 133 from coming out of the connecting slot, and the connection work is completed. The operation is simple, easy to disassemble and assemble, and convenient to replace the upper mold base 13.

[0023] As a further embodiment, the lifting mechanism 2 includes a lifting electric cylinder 21 installed on the upper end of the injection molding frame 12. The telescopic end of the lifting electric cylinder 21 passes through the injection molding frame 12 and is equipped with a lifting seat plate 23. A lifting guide rod 22 is also slidably inserted on the injection molding frame 12. The lower end of the lifting guide rod 22 is fixedly connected to the upper end of the lifting seat plate 23.

[0024] The working principle of the lifting mechanism 2 is as follows: by extending the lifting electric cylinder 21, the lifting seat plate 23 can be pushed down, thereby closing the upper mold base 13 and the lower mold base 14, thus facilitating the injection molding process.

[0025] As a further embodiment, the lower mold base 14 has a lower mold groove at its upper end, and the upper mold base 13 has an upper mold protrusion 131 at a corresponding position. The upper mold base 13 is also equipped with a feed pipe 132. In this embodiment, the upper mold protrusion 131 and the lower mold groove can be used to form a molding cavity. The molten raw material can be injected into the molding cavity through the feed pipe 132, thereby realizing the molding of the sealing ring.

[0026] As a further embodiment, a stripper plate 141 is slidably inserted into the lower mold groove of the lower mold base 14. A stripper guide rod 142 is provided at the lower end of the stripper plate 141. The lower end of the stripper guide rod 142 passes through the lower mold base 14 and is provided with an end cap. A stripper spring 143 is also fitted on the stripper guide rod 142. The two ends of the stripper spring 143 abut against the end cap and the corresponding side of the lower mold base 14, respectively. In this embodiment, a stripper port 144 is also provided at the lower end of the lower mold base 14. A stripper mechanism 3 is also installed at the upper end of the base 1. The stripper mechanism 3 includes a stripper frame 31 installed on the base 1. A stripper electric cylinder 32 is installed on the stripper frame 31. The telescopic end of the stripper electric cylinder 32 passes through the stripper frame 31 and is fixed with a stripper push plate 33.

[0027] The working principle of the stripping mechanism 3 is as follows: During stripping, the stripping electric cylinder 32 extends and pushes the stripping push plate 33 upward, so that the stripping push plate 33 extends into the stripping port 144, and then pushes the stripping plate 141 upward. At this time, the stripping guide rod 142 moves upward synchronously, and the stripping spring 143 is compressed, thereby pushing the formed sealing ring out of the lower mold base 14 for easy removal. When the stripping electric cylinder 32 retracts, the stripping spring 143 returns to its original state, and the end cap can be squeezed, thereby realizing the downward movement of the stripping plate 141, which facilitates the subsequent injection molding work.

[0028] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
