Description

Technical Field

[0001] This utility model relates to the field of powder molding manufacturing technology, and more specifically, to a box structure that can prevent deformation. Background Technology

[0002] A powder forming press is a device that presses metal powder or ceramic powder into a product of a fixed shape (such as a block). A powder forming press generally includes an upper housing, an upper mold mechanism, and a lower mold mechanism. The upper mold lifting drive device of the upper mold mechanism is generally installed on the top of the upper housing. For example, the powder forming press mold frame with an independently driven upper structure disclosed in utility model patent number CN221186930U includes a housing, an upper first lifting drive device, an upper second lifting drive device, an upper first plate, and an upper second plate. The upper second lifting drive device and the upper first lifting drive device are installed downwards through the upper end of the housing. The upper first lifting drive device and the upper second lifting drive device are arranged horizontally side by side at the same height. The upper second lifting drive device is connected to the upper second plate, and the upper first lifting drive device is connected to the upper first plate. The patented upper mold lifting drive device is installed side by side on the top of the box. During the pressing process, the top of the box serves as the force-bearing surface for the upper mold lifting drive device. Over time, it will deform. Such deformation will cause uneven gaps between the upper and lower parts when pressing and closing the mold, which will directly affect the pressing accuracy, size and shape of the product. This deformation may also cause defects such as cracks, breaks or deformation in the product, reducing the product quality. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a box structure that can effectively enhance the rigidity of the upper part of the box, provide more stable support and higher load-bearing capacity, and reduce the risk of box deformation.

[0004] To achieve the above objectives, this utility model provides a box structure that can prevent deformation, including a box body with a top plate and a bottom plate at its upper and lower ends, respectively. The box body is configured as a hollow tetrahedral frame structure. The upper part of the box body is provided with a reinforcing connection structure fixedly connected to the bottom of the top plate. A columnar channel is formed by extending downward from the top surface of the top plate and passing through the reinforcing connection structure. The reinforcing connection structure includes a first reinforcing rib, a second reinforcing rib, a third reinforcing rib, and a fourth reinforcing rib. One side of the first, second, third, and fourth reinforcing ribs is connected to the vertical edge constituting the box body frame, and the other side of each rib extends diagonally to connect with the outer wall of the columnar channel. The first, second, third, and fourth reinforcing ribs are all integrally cast with the box body.

[0005] Preferably, the first reinforcing rib, the second reinforcing rib, the third reinforcing rib, and the fourth reinforcing rib are connected in pairs symmetrically to the outer wall of the columnar channel and combined to form an X-shaped structure.

[0006] Preferably, the lower part of the columnar channel is provided with a rectangular through groove connecting its front and back sides.

[0007] Preferably, the device also includes four first crossbeams, each located in the upper middle part of the box body, with the four first crossbeams respectively connected between two adjacent vertical edges.

[0008] Preferably, the device also includes a second crossbeam, which consists of three beams located in the lower middle part of the box body. The three beams are connected between the vertical edges that make up the sides and back of the box body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model features a novel structure and a reasonable design. By providing a reinforced connection structure fixedly connected to the bottom of the top plate at the upper part of the box, and using an integral casting process to combine it with the box, the strength of the upper structure of the box is significantly improved. Its first, second, third, and fourth reinforcing ribs effectively enhance the rigidity of the upper part of the box, providing more stable support for the lifting drive device installed at this position, improving the load-bearing capacity of the box, reducing the risk of box deformation, and thus improving the molding quality of the product.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please refer to Figure 1 The present invention provides a box structure that can prevent deformation, including a box 1. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 4 As shown, the top and bottom ends of the box 1 can be provided with a top plate 11 and a bottom plate 12 respectively. The box 1 is set as a tetrahedral frame structure with a hollow interior and four open sides. The upper part of the box 1 is provided with a reinforcing connection structure fixedly connected to the bottom of the top plate 11. A columnar channel 111 is formed by extending downward from its top surface and passing through the reinforcing connection structure on the top plate 11.

[0020] Specifically, the reinforcing connection structure may include a first reinforcing rib 13, a second reinforcing rib 14, a third reinforcing rib 15, and a fourth reinforcing rib 16. One side of the first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15, and the fourth reinforcing rib 16 is connected to the vertical edge 17 that constitutes the frame of the box body 1, and the other side of the first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15, and the fourth reinforcing rib 16 extends diagonally to connect with the outer wall of the columnar channel 111.

[0021] In this embodiment, the first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15 and the fourth reinforcing rib 16 can all be integrally cast with the box body 1.

[0022] Among them, the first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15, and the fourth reinforcing rib 16 can guide and distribute the force applied to the top plate 11 to the surrounding frame structure, thereby preventing the top of the box 1 from being deformed due to local stress concentration.

[0023] like Figure 2 and Figure 3 As shown, preferably, the first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15 and the fourth reinforcing rib 16 can be connected in pairs symmetrically to the outer wall of the columnar channel 111 and combined to form an X-shaped structure.

[0024] Preferably, the X-shaped structure utilizes four cross-arranged reinforcing ribs, which can more effectively distribute and transmit the force applied to the top plate 11. Moreover, compared with parallel-arranged reinforcing ribs, the X-shaped connection can significantly improve the bending stiffness of the box 1, thereby reducing the risk of deformation at the top of the box 1.

[0025] Preferably, the lower part of the columnar channel 111 may be provided with a rectangular through groove 112 connecting its front and back sides. The columnar channel 111 can be used to install the transmission components of the upper two lifting drive devices 22 inside it. The operator can observe the working status of the transmission components more intuitively through the rectangular through groove 112, which improves operability and maintainability.

[0026] In addition, this embodiment may also include a first crossbeam 18, which has four beams and is located in the upper middle part of the box body 1. The four first crossbeams 18 are respectively connected between two adjacent vertical edges 17.

[0027] Furthermore, it may also include a second crossbeam 19, which has three sections all located in the lower middle part of the box body 1. The three second crossbeams 19 are respectively connected between the vertical edges 17 that make up the sides and back of the box body 1.

[0028] Among them, the first crossbeam 18 and the second crossbeam 19 provide stable support and effective protection for the installation of the upper and lower molds, and also improve the load-bearing capacity of the box 1.

[0029] like Figure 5 As shown, in specific implementation, Figure 5 This is an assembly diagram of a powder molding press mold frame installed in a deformation-preventing box structure. In this embodiment, a first accommodating space is formed between the first reinforcing rib 13 and the second reinforcing rib 14 for mounting the upper lifting drive device 21 of the powder molding press. A second accommodating space is formed between the third reinforcing rib 15 and the fourth reinforcing rib 16 for mounting the upper lifting drive device 21 (not shown) of the upper mold mechanism 2. The upper two lifting drive devices 22 can be fixedly mounted on the top surface of the top plate 11. Of course, Figure 5The illustration shown is only one embodiment of the present invention and does not imply that the present invention is limited to this embodiment.

[0030] In summary, this utility model provides a reinforced connection structure fixedly connected to the bottom of the top plate at the upper part of the box body. This structure is integrated with the box body using an integral casting process, which significantly improves the strength of the upper structure of the box body. The first, second, third, and fourth reinforcing ribs effectively enhance the rigidity of the upper part of the box body, providing more stable support for the lifting drive device installed at this position, improving the load-bearing capacity of the box body, reducing the risk of deformation of the box body, and thus improving the molding quality of the product.

[0031] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
