Description

Technical Field

[0001] This utility model relates to the technical field of automotive molds, and more specifically, to a reusable prototype beam side shaping shared mold frame and wedge mechanism. Background Technology

[0002] In the automotive industry, the chassis beam is a crucial component that supports the vehicle's structure, and its structural strength and precision are vital to the vehicle's safety and performance. To ensure the quality and precision of the chassis beam, complex shaping processes are often required, including front shaping and side shaping.

[0003] In traditional automotive frame forming processes, front forming and side forming are two common methods. Front forming is mainly used for materials with low tensile strength. Although this process results in less springback and better forming effect during the forming process, it still requires manual sheet metal adjustments to meet customer-required quality standards. Side forming, on the other hand, is suitable for high-strength materials and can be used to shape both sides of the frame using larger molds, making the frame more precise and stable. However, side forming molds are expensive to manufacture, typically weighing 7 to 8 tons per set, which increases manufacturing and transportation costs, and also results in a longer mold development cycle.

[0004] Furthermore, with the continuous development of the automotive industry, the market demand for small-batch customized production is increasing, and the traditional mold development model is gradually revealing many problems. Under the traditional model, the forming process of the chassis beam for each vehicle model requires the development of a separate mold, and the development of each mold requires a large amount of materials, casting, and machining time, resulting in wasted mold development costs. At the same time, because many vehicle models have similar designs and dimensions, using completely independent molds for production is not only inefficient but also leads to significant resource waste during the manufacturing process.

[0005] In the current automotive mold development process, the cost of mold casting and processing still accounts for a large proportion, especially in the trial production stage. For different car models and different specifications of frame parts, the mold manufacturing and adjustment cycle is lengthy, severely impacting the overall project production schedule. Since mold assets typically belong to the OEM (Original Equipment Manufacturer), mold manufacturers usually need to design and manufacture molds that meet the specific project requirements of different OEMs. Therefore, the mold reuse rate is low, resulting in high mold costs and long-term resource waste.

[0006] Therefore, how to reduce mold development costs, shorten mold design and manufacturing cycles, and improve mold utilization efficiency through a new technical solution has become an urgent problem to be solved in the current automotive mold design field. Utility Model Content

After positioning, the side tool block is completely fixed to the common side wedge with bolts through several screw holes on the bottom surface of the common side wedge to complete the installation.

[0014] In any of the above technical solutions, the shared lower die base further includes a punch positioning key;

[0015] The punch is positioned and fixed to the common lower die base by the punch positioning key located on the mounting surface of the common lower die base. The punch is then completely fixed to the common lower die base by bolts through the screw holes on the mounting surface of the common lower die base.

[0016] In any of the above technical solutions, the common lower die base further includes a clamping key; the punch is locked by the clamping key located on the side of the mounting surface of the common lower die base.

[0017] In any of the above technical solutions, the common lower mold base further includes: a side guide plate, a wedge lower mold guide plate, and a wedge positioning guide plate;

[0018] The side guide plate, the wedge lower mold guide plate, and the wedge positioning guide plate are all located on the side of the common lower mold base mounting surface. The side guide plate and the wedge lower mold guide plate are both raised flat plate structures. The wedge lower mold guide plate guides the sliding of the common side wedge. The wedge positioning guide plate is a raised triangular prism structure, which positions the sliding of the common side wedge.

[0019] In any of the above technical solutions, the shared upper mold base further includes: a central guide block and a first inclined wedge guide plate;

[0020] The central guide block and the first inclined wedge guide plate are distributed on both sides of the central axis of the common upper mold base mounting surface. The central guide block and the first inclined wedge guide plate guide the sliding of the common side inclined wedge, and the central guide block positions the common side inclined wedge.

[0021] In any of the above technical solutions, the common upper mold base further includes: a pressure plate limiting plate and a wedge limiting pressure plate;

[0022] The pressure plate limiting plate and the wedge limiting plate are located at the side edge of the common upper mold base mounting surface. The pressure plate limiting plate is located at the central axis position, and the wedge limiting plates are located on both sides of the central axis. The pressure plate limiting plate plays a limiting role for the pressure plate, and the wedge limiting plate plays a limiting role for the common side wedge.

[0024] The beneficial effects of this utility model are:

[0025] The technical solution of this utility model, by adopting a shared mold base and a shared wedge design, allows the main beam parts of different car models to be processed under the same mold frame, thereby avoiding the high cost of developing independent molds for each car model. This shared design significantly reduces the mold development cost and saves casting and processing costs by reducing the individual procurement of parts.

[0026] Through modular design and standardized mold base and wedge structure, this invention significantly shortens the mold development cycle.

By using a shared mold base and a shared wedge, it can meet the processing requirements of various types of beam parts, greatly improving the utilization rate of the mold. Especially for small-batch customized production, this design can be reused across multiple projects, reducing the demand for mold resources for a single project, thereby achieving efficient utilization of the mold.

[0028] The structural design of this invention ensures the stability and precision of each component. In particular, the installation and fixing method of the shared wedge ensures uniform pressure transmission and avoids deviations during the side forming process of the main beam. Furthermore, the punch positioning key and pressure plate limiting plate within the mold further guarantee the stability of the main beam parts during processing, thereby improving processing accuracy and consistency, and ensuring that every batch of parts meets quality requirements.

[0029] The mold of this invention has strong adaptability, allowing for rapid adjustment and switching based on the characteristics of the frame parts for different vehicle models. The mold design supports the on-the-spot switching between left and right parts, avoiding the cumbersome process of remaking different molds as in traditional mold making. This flexibility is particularly suitable for the current market demand for small-batch customized production, better meeting customers' individual needs and improving production flexibility and responsiveness.

Detailed Implementation

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0039] In the following description, many specific details are set forth in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figure 1 As shown, this embodiment provides a reusable prototype beam side shaping shared mold frame and wedge mechanism, including three parts: a shared lower mold base 1, a shared upper mold base 2, and a shared side shaping wedge 3.

[0041] The shared lower mold base 1 and the shared upper mold base 2 are the supporting frames of the mold, which play a role in fixing and supporting, ensuring stability during the processing; the shared side wedge 3 is the core component of the mold, which is responsible for converting vertical pressure into lateral pressure to complete the shaping of the side of the beam.

[0042] like Figure 3 As shown, the common lower mold base 1 is equipped with multiple functional components for supporting the mold, including: punch 4, side guide plate 9, clamping key 10, punch positioning key 11, wedge lower mold guide plate 12, and wedge positioning guide plate 13.

[0043] The punch 4 is positioned and fixed to the common lower die base 1 by the punch positioning key 11 located on the mounting surface of the common lower die base 1. The punch 4 is locked by the clamping key 10 located on the side of the mounting surface of the common lower die base 1. Then, the punch 4 is completely fixed to the common lower die base 1 by bolts through the screw holes on the mounting surface of the common lower die base 1 to complete the installation.

[0044] The side guide plate 9, the wedge lower die guide plate 12, and the wedge positioning guide plate 13 are all located on the side of the mounting surface of the common lower die base 1. The side guide plate 9 and the wedge lower die guide plate 12 are both raised flat plate structures. The wedge lower die guide plate 12 is used to guide the sliding of the common side wedge 3 during processing. The wedge positioning guide plate 13 is a raised triangular ridge structure used to position the sliding of the common side wedge 3. The side guide plate 9 is used to prevent the tool block from lateral deformation during processing and to ensure the consistency of processing effect.

[0045] like Figure 4 As shown, the common upper mold base 2 is the part that applies pressure to the material and completes the shaping. Its structure is flexible and includes: pressure plate 5, pressure plate nitrogen cylinder 7, center guide block 8, nitrogen cylinder bottom block 14, pressure plate limiting plate 15, first inclined wedge guide plate 16, inclined wedge nitrogen cylinder assembly 17, and inclined wedge limiting pressure plate 18.

[0046] The pressure plate nitrogen cylinder 7 and the nitrogen cylinder bottom block 14 are located at the central axis of the common upper mold base 2 mounting surface. During processing, the pressure plate nitrogen cylinder 7 is used to apply downward pressure to the pressure plate 5 to complete the shaping of the side of the beam. The nitrogen cylinder bottom block 14 is a raised flat plate structure, which is used to limit the shortest distance between the pressure plate 5 and the common upper mold base 2 mounting surface, and to prevent the pressure plate 5 from squeezing the pressure plate nitrogen cylinder 7 in the opposite direction and causing damage to the pressure plate nitrogen cylinder 7.

[0047] The central guide block 8, the first wedge guide plate 16, and the wedge nitrogen cylinder assembly 17 are distributed on both sides of the central axis of the mounting surface of the common upper mold base 2. The central guide block 8 and the first wedge guide plate 16 are used to guide the sliding of the common side wedge 3. The central guide block 8 plays a positioning role for the common side wedge 3. The wedge nitrogen cylinder assembly 17 is used to apply downward pressure to the common side wedge 3 during processing.

[0048] The pressure plate limiting plate 15 and the wedge limiting plate 18 are located at the side edge of the mounting surface of the common upper mold base 2. The pressure plate limiting plate 15 is located at the central axis position, and the wedge limiting plate 18 is located on both sides of the central axis. The pressure plate limiting plate 15 limits the pressure plate 5, and the wedge limiting plate 18 limits the common side wedge 3, so that the two cannot move beyond a certain range on the common upper mold base 2.

[0049] like Figure 5 and Figure 6 As shown, the common side-forming wedge 3 is located between the common lower mold base 1 and the common upper mold base 2. It is responsible for converting the vertical pressure into lateral pressure at a specific angle, thereby completing the side shaping of the beam. The common side-forming wedge 3 includes: a second wedge guide plate 19 and a tool block positioning key 20.

[0050] The common side wedge 3 body has an inclination angle of 60 degrees, and its design is optimized to adapt to the processing requirements of different vehicle models.

[0051] The second inclined wedge guide plate 19 is located on the side of the common side inclined wedge 3 and slides into contact with the inclined wedge limiting pressure plate 18 when it slides into the common upper mold base 2; the blade block positioning key 20 is located on the bottom surface of the common side inclined wedge 3 and is used to position the side blade block 6. After positioning, the side blade block 6 is completely fixed to the common side inclined wedge 3 with bolts through several screw holes on the bottom surface of the common side inclined wedge 3 to complete the installation.

[0052] The tool block positioning key 20 fixes the Y direction, with a Y-axis step distance of 105mm and an X-axis step distance of 180mm, and a total length of 1500mm. It can support the installation of side-aligning tool blocks 6 with a maximum length of 1600mm.

[0053] According to the above structure and the model of the beam to be processed, install the common lower mold base 1, the common upper mold base 2 and the common side wedge 3 respectively. After ensuring that the parts are not loose, place the beam in the common lower mold base 1 with the common lower mold base 1 as the base, fix the common side wedge 3 at the bottom of the common upper mold base 2, and make the common upper mold base 2 press down on the beam to process it.

[0054] In summary, this utility model proposes a reusable prototype beam side shaping shared mold frame and wedge mechanism, comprising three parts: a shared lower mold base 1, a shared upper mold base 2, and a shared side shaping wedge 3.

[0055] The common lower mold base 1 is the support frame of the mold. The surface of the common lower mold base 1 is provided with multiple functional components, including the punch 4 and the punch positioning key 11.

[0056] The punch 4 is positioned and fixed to the common lower die base 1 by the punch positioning key 11 located on the mounting surface of the common lower die base 1. Then, the punch 4 is completely fixed to the common lower die base 1 by bolts through the screw holes on the mounting surface of the common lower die base 1 to complete the installation.

[0057] The common upper mold base 2 is the part that applies pressure to the main beam. The common upper mold base 2 includes a pressure plate 5, a pressure plate nitrogen cylinder 7, a center guide block 8, a nitrogen cylinder bottom block 14, a first inclined wedge guide plate 16, and an inclined wedge nitrogen cylinder assembly 17.

[0058] The pressure plate nitrogen cylinder 7 and the nitrogen cylinder bottom block 14 are located at the central axis of the common upper mold base 2 mounting surface. During processing, the pressure plate nitrogen cylinder 7 is used to apply downward pressure to the pressure plate 5 to complete the shaping of the side of the beam. The nitrogen cylinder bottom block 14 is a raised flat plate structure, which limits the shortest distance between the pressure plate 5 and the common upper mold base 2 mounting surface, and prevents the pressure plate 5 from squeezing the pressure plate nitrogen cylinder 7 in the opposite direction and causing damage to the pressure plate nitrogen cylinder 7.

[0059] The central guide block 8, the first wedge guide plate 16, and the wedge nitrogen cylinder assembly 17 are distributed on both sides of the central axis of the mounting surface of the common upper mold base 2. The central guide block 8 and the first wedge guide plate 16 are used to guide the sliding of the common side wedge 3. The central guide block 8 plays a positioning role for the common side wedge 3. The wedge nitrogen cylinder assembly 17 is used to apply downward pressure to the common side wedge 3 during processing.

[0060] The shared side-forming wedge 3 is located between the shared lower mold base 1 and the shared upper mold base 2. It is responsible for converting vertical pressure into lateral pressure at a specific angle, thereby completing the side shaping of the beam. The shared side-forming wedge 3 includes a tool block positioning key 20.

[0061] The tool block positioning key 20 is located on the bottom surface of the common side wedge 3 and is used to position the side tool block 6. After positioning, the side tool block 6 is completely fixed to the common side wedge 3 by bolts through several screw holes on the bottom surface of the common side wedge 3 to complete the installation.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium.
