[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-3 As shown, this utility model proposes a foam molding mold for car backrests, including an upper mold 1 and a lower mold 2, which are fitted together and detachable. Positioning blocks 3 are provided at both ends of the upper mold 1, and a first notch is provided at the bottom end of each positioning block 3. Matching blocks 4 are provided at both ends of the lower mold 2, and the matching blocks 4 can extend into the first notch and slide against its inner wall. A baffle 10 is provided at the first notch, and the matching blocks 4 can move to slide against the baffle 10 and the outer end of the upper mold 1, respectively.

[0023] In this invention, when installing the upper mold 1 and the lower mold 2, the worker inserts the mating block 4 into the first notch. Since the mating block 4 slides against the inner wall of the first notch, it can be initially positioned. When the mating block 4 is inserted into the first notch, it is located between the baffle 10 and the upper mold 1. The baffle 10 and the outer end of the upper mold 1 further limit the position of the mating block 4, thereby completing the precise positioning of the lower mold 2. This device achieves precise positioning of the mold through the mating block 4 and the positioning block 3, avoiding the errors and increased workload caused by manual positioning. Compared with the prior art, this technical solution not only improves the installation accuracy of the mold, but also simplifies the installation process, thereby improving production efficiency and product quality.

[0024] Furthermore, this application also proposes that the positioning block 3 is provided with a strip-shaped through hole that communicates with the first notch. The inner walls of the two ends of the strip-shaped through hole are respectively located on both sides of the inner walls of the two ends of the first notch. The mating block 4 can slide into the strip-shaped through hole. A limiting component is provided between the mating block 4 and the strip-shaped through hole for limiting the mating block 4 and the bottom wall of the strip-shaped through hole. After the positioning of the upper mold 1 and the lower mold 2 is completed, the limiting component can be directly placed between the mating block 4 and the bottom wall of the strip-shaped through hole, thereby completing the limiting between the mating block 4 and the bottom wall of the strip-shaped through hole through the limiting component, thereby completing the limiting of the upper mold 1 and the lower mold 2.

[0025] Furthermore, this application also proposes that, in the automotive backrest foam molding mold, a connecting plate 5 and a force transmission block 6 are introduced to enhance the positioning and force transmission functions of the mold. The force transmission block 6 is located above the mating block 4 and is connected to the mating block 4 through the connecting plate 5. The limiting component is set between the bottom wall of the strip-shaped through hole and the force transmission block 6 to ensure that the mating block 4 can be effectively limited during the sliding process in the strip-shaped through hole.

[0026] The design of the connecting plate 5 enables the force transmission block 6 to stably transmit force to the mating block 4, thereby improving the positioning accuracy of the mold.

[0027] Furthermore, this application also proposes that the limiting component includes a mounting plate 7 and a push plate 9. The mounting plate 7 is located between the bottom wall of the strip-shaped through hole and the force transmission block 6. Push plates 9 are provided at intervals at both the upper and lower ends of the mounting plate 7. The two push plates 9 can be moved to abut against the bottom wall of the strip-shaped through hole and the force transmission block 6, respectively. The mounting plate 7 is provided with a driving unit for driving the two push plates 9 to move closer or further away from each other.

[0028] Specifically, the mounting plate 7, as the core component of the limiting assembly, has push plates 9 at its upper and lower ends, respectively. The push plates 9 are moved by a drive unit. By controlling the drive unit, the position of the push plates 9 can be precisely adjusted to abut against the bottom wall of the strip-shaped through hole or the force transmission block 6, thereby achieving the limiting function. This pushes the force transmission block 6 upwards and simultaneously pushes the positioning block 3 downwards, thus completing the installation of the upper mold 1 and the lower mold 2. There is a gap between the push plates 9 and the inner walls of the strip-shaped through hole on both sides to ensure that the push plates 9 are not obstructed during movement. Compared to conventional bolt installation, this device makes disassembly of the upper and lower molds very simple; it only requires removing the abutment between the push plates 9 and the force transmission block 6 and the bottom wall of the strip-shaped through hole, and then removing the push plates 9 and the mounting plate 7, greatly reducing the difficulty for workers in fixing the upper mold 1 and the lower mold 2.

[0029] Furthermore, this application also proposes that the drive unit includes two electric telescopic cylinders 8, the fixed ends of the two electric telescopic cylinders 8 are respectively connected to the upper and lower ends of the mounting plate 7, and the telescopic rods of the two electric telescopic cylinders 8 are both vertically arranged and respectively connected to two push plates 9.

[0030] In a preferred embodiment, the telescopic rod of the electric telescopic cylinder 8 is fixed to the push plate 9 via a connector. The connector can be made of bolts or clips to ensure a firm and reliable connection between the push plate 9 and the telescopic rod. Furthermore, the surface of the push plate 9 can be provided with anti-slip textures or rubber pads to increase the friction between it and the bottom wall of the strip-shaped through hole or the force transmission block 6, further improving the limiting effect.

[0031] Therefore, this technical solution, through the cooperation of mounting plate 7, push plate 9, and electric telescopic cylinder 8, achieves precise positioning of mating block 4 and the bottom wall of the strip-shaped through hole. Compared with existing technologies, this solution not only reduces the need for manual positioning and lowers the workload of workers, but also improves the accuracy of mold installation, thereby enhancing production quality. Specifically, the automated control of electric telescopic cylinder 8 makes the movement of push plate 9 more precise, avoiding errors that may be caused by manual operation, and further ensuring the stability of mold installation.

[0032] Furthermore, this application proposes a gap between the push plate 9 and the inner walls of both sides of the strip-shaped through hole. This gap allows the push plate 9 to move freely within the strip-shaped through hole to a certain extent, thereby avoiding direct contact between the push plate 9 and the inner wall of the strip-shaped through hole, reducing friction and wear. Specifically, the size of the gap can be adjusted according to actual needs to ensure that the push plate 9 does not experience excessive resistance during movement, while maintaining an appropriate distance from the inner wall of the strip-shaped through hole. As a preferred embodiment, the width of the gap can be between 0.5 mm and 2 mm to ensure the flexibility and stability of the push plate 9.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
