Description

Technical Field

[0001] This utility model relates to the field of die-casting structure technology, and in particular to an integrated die-casting structure for a steering gear housing. Background Technology

[0002] In the automotive parts manufacturing industry, the steering gear, as the core component of the vehicle steering system, directly affects the vehicle's handling stability and driving safety. As the key structural carrier of the steering gear, the steering gear housing not only needs to provide stable support and precise positioning for the internal precision transmission mechanism, but also needs to have sufficient strength and rigidity to withstand the test of complex and varied external loads and harsh working conditions.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the die casting process, the molten metal rapidly fills the mold cavity under high pressure and then solidifies under high pressure. Since the molten metal will shrink in volume during the solidification process, if there is no reliable locking mechanism to securely lock the mold, the parting surfaces of the mold are very likely to produce small relative displacements or gaps due to the shrinkage force of the molten metal. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology lacks an effective die-casting locking mechanism. To address this, we propose an integrated die-casting structure for the steering gear housing.

[0005] To achieve the above objectives, this application adopts the following technical solution: an integrated die-casting structure for a steering gear housing, comprising a die-casting structure body, an upper mold mounted on the top of the die-casting structure body, fixing blocks fixedly connected to all four sides of the die-casting structure body, limiting blocks fixedly connected to all four sides of the upper mold, an extension plate slidably connected inside the fixing blocks, a vertical groove opened at the front end of the extension plate, several limiting grooves opened on both sides of the vertical groove, an adjustment box fixedly connected to the front end of the limiting block, adjustment grooves opened on both sides of the adjustment box, an adjustment block slidably connected inside the adjustment groove, a through groove opened on the side of the adjustment groove near the die-casting structure body, and a through block fixedly connected to the side of the adjustment block near the limiting groove.

[0006] Preferably, guide grooves are provided on both sides of the inside of the fixed block, and guide blocks are fixedly connected to both sides of the extension plate, with the surface of the guide blocks slidingly connected to the inside of the guide grooves.

[0007] Preferably, the size of the through block is adapted to the size of the limiting groove, and the surface of the through block is inserted into the interior of the limiting groove.

[0008] Preferably, thrust springs are fixedly connected to both sides of the bottom end inside the fixed block, and the top of the thrust springs is fixedly connected to the bottom end of the extension plate.

[0009] Preferably, both ends of the adjusting groove are provided with limiting grooves, and both ends of the adjusting block are fixedly connected with limiting blocks, and the surface of the limiting block is slidably connected to the inside of the limiting groove.

[0010] Preferably, a return spring is fixedly connected to the side of the adjusting block near the inside of the adjusting groove, and the side of the return spring away from the adjusting block is fixedly connected to the inside of the adjusting groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, during the die-casting operation, the worker pushes the adjusting block into the adjusting groove, causing the adjusting block to move the through block and move the rear end of the through block into the vertical groove, thereby releasing the limit between the through block and the limiting groove and closing the die-casting structure body and the upper mold. At the same time, the adjusting block is pulled to make the through block re-limit the adjusting box, thus preventing displacement during the die-casting process. Attached Figure Description

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an integrated die-casting structure for a steering gear housing, including a die-casting structure body 1, an upper mold 2 installed on the top of the die-casting structure body 1, fixing blocks 3 fixedly connected around the four sides of the die-casting structure body 1, limiting blocks 4 fixedly connected around the four sides of the upper mold 2, an extension plate 5 slidably connected inside the fixing block 3, a vertical groove 6 opened at the front end of the extension plate 5, several limiting grooves 7 opened on both sides of the vertical groove 6, an adjustment box 8 fixedly connected at the front end of the limiting block 4, an adjustment groove 9 opened on both sides of the adjustment box 8, an adjustment block 10 slidably connected inside the adjustment groove 9, a through groove 11 opened on the side of the adjustment groove 9 near the die-casting structure body 1, and a through block 12 fixedly connected on the side of the adjustment block 10 near the limiting groove 7.

[0022] The above solution is adopted: When the worker is die casting, he pushes the adjusting block 10 into the adjusting groove 9, so that the adjusting block 10 moves the through block 12 and moves the rear end of the through block 12 into the vertical groove 6, so that the limit between the through block 12 and the limiting groove 7 is released, and the die casting structure body 1 and the upper mold 2 are closed. At the same time, the adjusting block 10 is pulled so that the through block 12 re-forms the limit with the adjusting box 8, so as to avoid displacement during the die casting process.

[0023] Reference Figure 3 As shown in this embodiment: guide grooves 13 are provided on both sides of the inside of the fixed block 3, and guide blocks 14 are fixedly connected to both sides of the extension plate 5. The surface of the guide block 14 is slidably connected to the inside of the guide groove 13.

[0024] The above solution is adopted: the guide block 14 slides inside the guide groove 13, which makes the extension plate 5 more stable when it moves inside the fixed block 3, and avoids the phenomenon of the extension plate 5 shifting or shaking during the sliding process. This sliding connection method not only improves the stability of die casting, but also ensures that the die casting operation can be carried out accurately.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment: the size of the through block 12 is adapted to the size of the limiting groove 7, and the surface of the through block 12 is inserted into the interior of the limiting groove 7;

[0026] By adopting the above scheme, when the through block 12 is accurately inserted into the limiting groove 7, a stable limiting structure is formed, which effectively prevents the die-casting structure body 1 and the upper mold 2 from accidentally separating during the die-casting process, thus ensuring the safety and stability of the die-casting operation.

[0027] Reference Figure 3 As shown in this embodiment: both sides of the bottom of the fixed block 3 are fixedly connected with thrust springs 15, and the top of the thrust springs 15 is fixedly connected to the bottom of the extension plate 5.

[0028] Using the above scheme: when the worker pushes the extension plate 5 into the interior of the fixed block 3, the extension plate 5 compresses the thrust spring 15 to store force and removes the limit between the extension plate 5 and the limiting block 4. When the worker releases the limit of the extension plate 5, the extension plate 5 can move upward quickly under the action of the rebound force of the thrust spring 15, making the operation more convenient and reducing the labor intensity of the worker.

[0029] Reference Figure 5 As shown in this embodiment: both ends of the adjusting groove 9 are provided with limiting grooves 16, and both ends of the adjusting block 10 are fixedly connected with limiting blocks 17, and the surface of the limiting block 17 is slidably connected to the inside of the limiting groove 16.

[0030] The above scheme is adopted: when the adjusting block 10 slides and adjusts inside the adjusting groove 9, the limiting block 17 slides inside the limiting groove 16 accordingly. This structure effectively limits the sliding trajectory of the adjusting block 10, prevents the adjusting block 10 from deviating during the adjustment process, and ensures that the adjusting block 10 can slide stably inside the adjusting groove 9, further improving the stability and reliability of the die-cast structure body 1 during use.

[0031] Reference Figure 5 As shown, in this embodiment: a return spring 18 is fixedly connected to the side of the adjusting block 10 near the inside of the adjusting groove 9, and the side of the return spring 18 away from the adjusting block 10 is fixedly connected to the inside of the adjusting groove 9.

[0032] The above scheme is adopted: when the operator moves the adjusting block 10 into the adjusting groove 9, the adjusting block 10 compresses the return spring 18 to store force, and drives the through block 12 to release the limit between it and the adjusting box 8. When the operator releases the adjusting block 10, under the action of the return spring 18, the through block 12 quickly resets and re-establishes the limit with the adjusting box 8, thereby achieving a stable fixation of the steering gear housing. This design not only simplifies the operation process and improves work efficiency, but also ensures the stability and reliability of the connection between the adjusting block 10 and the adjusting groove 9 through the compression and rebound force of the return spring 18.

[0033] Working principle: During the die casting operation, the operator pushes the adjusting block 10 into the adjusting groove 9, causing the adjusting block 10 to move the through block 12 and move the rear end of the through block 12 into the vertical groove 6, thereby releasing the limit between the through block 12 and the limiting groove 7, and closing the die casting structure body 1 and the upper mold 2. At the same time, the adjusting block 10 is pulled to make the through block 12 re-limit the adjusting box 8, thus preventing displacement during the die casting process.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
