[0044] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1-Figure 2 As shown, the utility model provides a shelf beam for carrying and transporting material boxes or goods. The shelf beam is provided with a transport end in its length direction, and the cross section of the shelf beam in the width direction is U-shaped. The shelf beam includes a load-bearing plate 1 and two support plates 2. The load-bearing plate 1 is configured to carry the material boxes in the transport process, and the material boxes can move along the length direction of the load-bearing plate 1; the two support plates 2 are respectively connected to the two sides of the width direction of the load-bearing plate 1. At the transport end, the load-bearing plate 1 and the two support plates 2 are both provided with a bending portion 100 pointing to the inner concave side of the shelf beam.

[0046] The cross-section of the shelf beam in the width direction is U-shaped, and is provided with an inner concave side surrounded by a load-bearing plate 1 and two support plates 2, which ensures the bearing capacity of the shelf beam while reducing its own weight. The bending portion 100 arranged at the transfer end can reduce the friction between the shelf beam and the material box or goods, thereby suppressing noise and preventing the edge of the transfer end from scratching the material box or goods.

[0047] Specifically, each support plate 2 and the bearing plate 1 are provided with rounded corners at their joints, which can prevent the shelf beam structure from rubbing against the bottom of the material box, and also prevent the edge of the shelf beam from being too sharp to scratch workers, thereby improving safety.

[0048] The utility model also provides a forming mold, such as Figure 3-Figure 4As shown, the forming mold is configured to die-cast the plate into the above-mentioned shelf beam, and the forming mold includes a die-casting head 3, a die-casting plate 4 and a driving mechanism 5. The die-casting head 3 is in the shape of a long strip, and a chamfered surface 31 is provided at the end vertex of the die-casting head 3 in the length direction; the die-casting plate 4 is configured to carry the plate, and a die-casting groove is provided on the side of the die-casting plate 4 facing the die-casting head 3, and an inward-retracting surface 401 is provided on the inner wall of the end of the die-casting groove, and the chamfered surface 31 corresponds to the inward-retracting surface 401 one by one. The die-casting head 3 can press the plate into the die-casting groove and form a shelf beam, and the bending portion 100 is formed between the chamfered surface 31 and the inward-retracting surface 401; the driving mechanism 5 is configured to drive the die-casting head 3 and the die-casting plate 4 to move closer to or away from each other.

[0049] The shelf beams die-cast by the forming mold all have the beneficial effects of the above-mentioned shelf beams, which will not be elaborated here. At the same time, the forming mold has high die-casting efficiency and uniform specifications; the setting of the inward surface 401 and the beveled surface 31 enables the forming mold to die-cast the bending portion 100 of the shelf beam during the downward pressing process of the die-casting head 3, which is more efficient than the traditional method of manual polishing after die-casting; and the traditional method of manual polishing of the bending portion 100 will reduce the material thickness of the transfer end of the shelf beam, affecting the local bearing capacity of the transfer end, while the forming mold will not change the material thickness during the die-casting process, which has less impact on the local bearing capacity of the transfer end and has higher reliability.

[0050] In this embodiment, the driving mechanism 5 is a hydraulic rod structure commonly used in the art, which will not be described in detail here.

[0051] In this embodiment, two driving mechanisms 5 are arranged at intervals. In other embodiments, the number of driving mechanisms 5 can be adaptively adjusted according to the sizes of the die-casting head 3 and the die-casting plate 4 so that the die-casting head 3 can provide uniform downward pressure to the plate.

[0052] Specifically, the die-casting plate 4 includes a fixed plate 41 and a replacement plate 42. The replacement plate 42 is detachably connected to the end of the fixed plate 41 relative to the chamfered surface 31, the die-casting groove is through-opened on the fixed plate 41 and the replacement plate 42, and the inner retracted surface 401 is provided on the replacement plate 42. The above arrangement can change the length, bending angle and shape of the bending portion 100 by replacing the replacement plate 42, the die-casting head 3 can be replaced in a variety of ways, and the replacement plate 42 can also be replaced in a variety of ways. The die-casting head 3 corresponds to the replacement plate 42 one by one to enhance the versatility of the molding die.

[0053] More specifically, a clamping protrusion 421 is provided on one side of the replacement plate 42 facing the fixed plate 41, and a clamping groove is provided on the fixed plate 41, and the clamping protrusion 421 can be clamped into the clamping groove. The above arrangement enables workers to connect the replacement plate 42 to the fixed plate 41 without using tools.

[0054] More specifically, the bottom of the slot faces the replacement plate 42, and in the direction away from the bottom of the slot, the two slot walls of the slot gradually approach each other, and the protrusion 421 can fit the bottom of the slot and the slot wall. The above arrangement allows the protrusion 421 to slide into or out of the slot only along the through direction of the slot, making the connection between the replacement plate 42 and the fixed plate 41 more secure.

[0055] Specifically, a pressure block 6 may be provided in the die casting tank, and the pressure block 6 can slide along the depth direction of the die casting tank, and the pressure block 6 is configured to support the side of the plate facing away from the die casting head 3. The arrangement of the pressure block 6 makes the shelf beam more stable during the die casting process.

[0056] Specifically, an anti-slip structure is provided on the side of the pressure block 6 facing the die casting head 3. The provision of the anti-slip structure can prevent relative sliding between the die casting head 3 and the pressure block 6 during the die casting process, thereby avoiding affecting the molding quality.

[0057] In this embodiment, the anti-skid structure can be an anti-skid pad, such as a rubber pad, or the anti-skid structure can be an anti-skid protrusion, which can be a dot-shaped protrusion or a pattern protrusion of any shape, as long as it can increase the contact friction between the position where it is located and the die-casting head 3. The specific form is referred to the prior art and is not specifically limited in this embodiment.

[0058] Specifically, the die casting plate 4 is provided with a limit column 43, and when the shelf beam is formed, the top plate 7 is pressed against the limit column 43. The above arrangement can prevent the die casting head 3 from being over-pressed, thereby damaging the plate.

[0059] In this embodiment, the forming mold further includes a top plate 7 and a base 8. The top plate 7 is detachably connected to the side of the die casting head 3 facing away from the die casting plate 4, and the top plate 7 is connected to the fixed end of the driving mechanism 5; the die casting plate 4 is detachably arranged on the base 8, and the base 8 is connected to the output end of the driving mechanism 5. The above arrangement can improve the integrity of the forming mold and facilitate the replacement of different types of die casting heads 3, and the die casting head 3 and the limiting column 43 are both screwed to the limiting column 43, and the die casting plate 4 is screwed to the base 8.

[0060] In this embodiment, the limiting column 43 is screwed to the die-cast plate 4, and is provided with a plurality of different lengths. The limiting column 43 of a suitable length can be selected according to the size of the shelf beam, and has strong versatility.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
