[0007] In some ways, the utility model provides a mould pressing tray for rectangular, adopt multiple reinforcing rib, first reinforcing rib is located at the edge of rectangular tray, and is connected with the supporting leg of tray edge;Second reinforcing rib is "Y" letter shape reinforcing structure, and the three end points of "Y" letter shape structure outward are connected with first reinforcing rib and supporting leg respectively, and the "Y" center of it is located in tray.In the tray provided by the utility model, the goods loaded and transported by mould pressing tray is square, in order to fix goods, prevent from inclining, sliding and the like in the process of transportation due to jolt, the supporting surface of tray is provided with multiple limit blocks.The limit block is some convex structure, and the edge of multiple convex structures in different directions is enclosed to form square limit block, which is consistent with the size of the bottom of goods, and the edge of convex structure is consistent with the inner edge of goods, and the convex surface is used to support the bottom disc of goods.The two edges of one limit block are clamped with the two edges of the inner side of the bottom of one square goods, or multiple limit blocks constitute three edges of square structure or complete square, and correspondingly clamped with three edges or four edges of the bottom of one square goods.The limit block is immediately adjacent to the connecting portion of supporting leg or reinforcing rib, so that, in each position of limit block fixedly placed goods, some positions take supporting leg as support point to support square goods, and some positions take the center of "Y" letter shape structure of second reinforcing rib or the connecting portion of first reinforcing rib and second reinforcing rib as support point to support square goods, so as to ensure that each square goods is fixed while also having support point to support its gravity.At the same time, the center point of "Y" letter shape structure of second reinforcing rib and the connecting point of reinforcing rib are symmetrically distributed, so that the structure of the whole tray is symmetrical, when loading square goods, ensure uniform dispersion of goods gravity, so that the tray is not easy to incline, improve the carrying capacity while improving stability.

[0008] Further, the tray further includes edge supporting legs located at the middle and four corners of the tray edge and a center supporting leg located at the center position of the tray, the middle edge supporting leg and the four corner supporting legs of the tray are connected by the first reinforcing rib, and the middle edge supporting leg of the tray is connected with the first reinforcing rib of adjacent edge and the center supporting leg by the second reinforcing rib.

[0009] In some embodiments, the supporting legs with the same size and height are arranged at the corners of the rectangular tray, the middle of the four sides and the center of the tray, the number of the supporting legs increases the load capacity of the tray, and the distribution of the positions improves the stability of the tray. The supporting legs are connected by the reinforcing ribs, wherein the first reinforcing ribs connect the middle supporting legs of the edges and the corner supporting legs, and the second reinforcing ribs are in the "Y" shape reinforcing structure connecting the center supporting leg, the middle supporting leg of the edge, and the middle position of the first reinforcing rib of the adjacent side. Therefore, the connecting points of the tray, the first reinforcing ribs and the second reinforcing ribs, and the center points of the "Y" shape structure can all be used as the supporting points of the tray, and are evenly distributed on the tray, so that the square goods are supported and the gravity is evenly dispersed when placed, thereby making the whole tray more stable.

[0010] Further, the edge of the tray includes a first edge and a second edge, the first end point of the second reinforcing rib connects the middle position of the first reinforcing rib of the first edge of the tray, the second end point connects the middle supporting leg of the second edge of the tray, and the third end point connects the center supporting leg.

[0011] In some embodiments, the second reinforcing rib is in the "Y" shape reinforcing structure, one of the end points of which connects the center position of the first reinforcing rib of the first edge, and the other two end points connect the supporting legs. Such a position design makes the square structure composed of the limiting blocks have a supporting point below, so that each square good is supported after being placed. Meanwhile, the second reinforcing rib is symmetrically distributed, which on the one hand enhances the strength and rigidity of the tray, and on the other hand effectively disperses the pressure, improves the load capacity, and thereby reduces the deformation and damage of the tray.

[0012] Further, the center supporting leg is connected to the middle supporting leg of the first edge of the tray by the third reinforcing rib.

[0013] In some embodiments, the center supporting leg of the tray is connected to the edge of the tray by the second reinforcing rib, and is also connected to the middle supporting leg of the first edge by the third reinforcing rib, so that the middle supporting leg of the first edge is connected to three reinforcing ribs at the same time, thereby improving the load capacity of the position and preventing the deformation of the middle. Moreover, in such a design, the center supporting leg is connected to six reinforcing ribs at the same time, which greatly improves the load capacity of the center position of the tray, and the symmetric distribution of the six reinforcing ribs further improves the stability of the tray when loading goods.

[0014] Further, the molded tray further includes a supporting surface, and the limiting blocks are arranged on the supporting surface.

[0015] In some ways, the reinforcing ribs are provided with a supporting surface for placing goods, and the limiting blocks are some protruding structures above the supporting surface. According to the position of the reinforcing ribs, the tray of the utility model is vertically symmetrical, and the supporting surface for loading goods is also symmetrically distributed. Such a design is beneficial to the uniform stress of the tray, and can make the goods more regular and stable.

[0016] Further, the limiting blocks are engaged with the inner side edges of the bottom of the goods to fix the goods.

[0017] In some ways, the bottom and edges of the loaded square goods have a certain height difference, the protruding height of the limiting block is consistent with the height difference of the bottom of the square goods, the position of the protrusion of the limiting block can support the goods to a certain extent, and the edge of the limiting block is designed to match the pattern of the inner side of the bottom of the square goods. Therefore, when placing the goods, the inner side of the bottom of the square goods is aligned with the edge of the limiting block, and the limiting block can accurately engage with the edge of the inner side of the bottom of the goods to fix the goods, so that the goods are not easily slipped or the like. The square structure composed of the limiting blocks can fix one square good, and the supporting surface provided with a plurality of limiting blocks can load a plurality of square goods. Since the reinforcing ribs and the supporting legs provide great support and stability for the tray, the tray still has high stability and carrying capacity when transporting a plurality of goods, and is not easily deformed.

[0018] Further, the two edges of the limiting block are rounded.

[0019] Since the general molded tray may not completely match the reinforcing ribs or grooves on the surface of the tray when loading the square goods, the square goods may be easily slipped or inclined, which may damage the tray and cause accidents. At the same time, the corners of the square goods may become stress concentration points, which may cause the local stress of the tray to be too large, and may cause deformation or damage, affecting the service life. Therefore, in the molded tray provided by the utility model, the corners of each limiting block are designed to be rounded, instead of being right-angled like the bottom of the square goods. Compared with the right angle, the rounded limiting block can disperse stress and avoid stress concentration when engaged with the square goods, reducing the risk of cracking or damage of the tray structure and prolonging the service life of the tray. At the same time, when loading the square goods, the limiting block is easier to align with the goods and slide in, reducing the operation difficulty.

[0020] Further, the goods are square.

[0021] In some ways, the tray can fix and load one or more square goods, and at most 20 square goods can be placed. When the number of goods to be transported is less than the upper limit of the goods that can be loaded on the tray, the goods are generally placed uniformly according to the symmetrical layout. If the number of goods is odd, the last good is placed according to the stress condition of the tray to ensure that the entire structure maintains stability and to avoid side turning, slipping and the like during transportation.

[0022] In some modes, the tray shape is rectangular, and 20 square goods can be fixedly placed according to a 4*5 arrangement. Such an arrangement not only fully utilizes the size of the tray, improves the transportation efficiency, but also arranges the goods between the goods in a regular and compact manner when the tray is full of goods, so that the tray is uniformly stressed, and is more stable and safe in the transportation process.

[0023] Further, the first reinforcing rib is arc-shaped, and the arc top of the arc-shaped reinforcing rib faces the tray edge.

[0024] In some modes, the first reinforcing rib is arranged between the middle edge support and the two end supports, is close to straight but has a certain arc, and the arc top faces the edge position of the tray. The position and shape of the first reinforcing rib improve the bearing capacity of the tray on the one hand, and make the stress of the tray more dispersed on the other hand, so that the stress concentration with the second reinforcing rib is avoided, and the tray is not deformed and damaged.

[0025] Further, the outer surfaces of the edge supports and the center support are provided with stepped surfaces, and the edge supports and the center support are in the same height.

[0026] In some modes, the tray in the utility model adopts a 9-support tray form, including one center support, four corner supports and four middle edge supports, and the bottom of the support is provided with a support plate. The positions of the nine supports are uniformly distributed, and the heights are consistent, so that the stress of the tray is uniformly distributed, and the stepped surfaces of the outer surfaces of the supports are beneficial to maintaining the strength of the supports and facilitating mold opening.

[0027] The utility model has the following beneficial effects:

[0028] 1. The mold pressing tray is provided with reinforcing ribs at the edge and the center position, and the "Y" shaped reinforcing ribs are designed on the bearing area, so that the stress of the whole tray is uniform, and the bearing capacity and stability of the tray are improved.

[0038] The utility model will be further described in detail below in combination with the drawings and examples. It should be pointed out that the following examples are intended to facilitate the understanding of the utility model and do not limit the utility model.

[0039] Example 1, a molded tray

[0040] As shown in Figures 1-7 The molded tray provided by the utility model comprises a limiting block 1, a supporting surface 2, a supporting leg 3, a supporting plate 4, a first reinforcing rib 5, a second reinforcing rib 6 and a third reinforcing rib 7. The supporting surface 2 is provided with a plurality of limiting blocks 1, and the supporting leg 3 comprises a central supporting leg 3-1, an edge middle supporting leg 3-2 and a four-corner supporting leg 3-3. The molded tray is used for loading square cargos.

[0041] As shown in Figure 1As shown, the edge 8 of the molded tray can be divided into a first edge 8-1 and a second edge 8-2, the first reinforcing rib 5 connects the middle foot 3-2 and the corner foot 3-3 in the middle of the edge, and the second reinforcing rib 6 is in the shape of a "Y" and includes four, symmetrically arranged on the tray. The first end point 6-1 of one second reinforcing rib 6 connects the middle of the first reinforcing rib 5 in the first edge 8-1, the second end point 6-2 connects the middle foot 3-2 in the second edge 8-2, and the third end point 6-3 connects the center foot 3-1. In this way, the four second reinforcing ribs 6 simultaneously connect the four middle feet of the edge and the four first reinforcing ribs 5, and the other end is commonly connected to the center foot 3-1, and is symmetrically distributed. At the same time, the center foot 3-1 is also connected to the two middle feet 3-2 of the first edge through the third reinforcing rib 7. From the overall structure of the tray, although the molded tray only provides nine feet to provide main support force, the "Y" center of the second reinforcing rib 6 and the connection between the first reinforcing rib 5 and the second reinforcing rib 6 also act as fulcrums to provide force support below the square structure composed of corresponding limiting blocks, so that when the tray carries square goods, it ensures that each square good has a support point when placed, and the gravity is evenly distributed. In addition, the center foot 3-1 is connected to six reinforcing ribs at the same time, so that the carrying capacity of the center position of the tray is further improved, so the position design of the reinforcing rib determines the force distribution of the tray, greatly improving the carrying capacity of the tray. At the same time, the first reinforcing rib 5 has an arc and the arc top faces the edge of the tray, so that the force on the tray is more dispersed, avoiding the concentration of force on the second reinforcing rib, which causes the tray to deform and damage.

[0042] As Figure 2 and 3As shown, a support surface 2 is provided between the reinforcing ribs. According to the position of the second reinforcing rib 6, the support area 2 can have four first support surfaces 2-1, four second support surfaces 2-2, and two central support surfaces 2-3. The support surface 2 is provided with multiple limiting blocks 1. The first support surface 2-1 includes four limiting blocks 9, 10, 11, and 12. The second support surface 2-2 includes four limiting blocks 13, 14, 15, and 16. The central support surface 2-3 includes two limiting blocks 17, 18, 19, 20, 21, and 22. The limiting block 9 is connected to the four corner supports 3-3 of the pallet, and its rounded corners engage with the inner bottom edge of the square goods to secure them. The rounded corners of limiting block 10 and limiting block 13 together form three sides of a square. The rounded corners of the two limiting blocks 11, together with the rounded corners of limiting blocks 17 and 20, form three sides of two squares respectively. At the same time, the rounded corners of the two limiting blocks 14 form three sides of a square. The rounded corners of limiting blocks 12, 15, and 18 together form a square. The rounded corners of the two limiting blocks 16 and 19 together form a square. With this configuration, a total of 20 square goods containers can be fixed on the supporting surface 2. Meanwhile, the height of the limiting block 1 is consistent with the height difference between the bottom and the edge of the cargo bucket, providing a certain support for the cargo bucket; the arc-shaped pattern on the edge of the limiting block 1 matches the pattern on the bottom of the cargo bucket, which can better fix the cargo and play an anti-slip role; the corners of the limiting block 1 are rounded, which can disperse stress when engaging with square cargo, avoid stress concentration, reduce the risk of pallet structure cracking or damage, and extend the service life of the pallet.

[0043] As shown in Figure 5, the molded pallet is supported by nine feet 3, including a central foot 3-1, four edge feet 3-2, and four corner feet 3-3. The feet 3 are truncated cones with a wide opening and a narrow bottom. Compared to existing columnar or cuboid feet, the feet used in this invention have a wider bearing surface, which is beneficial for the flatness of the pallet's support area and the uniform distribution of stress. Furthermore, the nine feet are all the same height, and the outer surface of the feet has stepped surfaces, ensuring both uniform stress on the pallet and the strength and rigidity of the feet themselves, further improving the pallet's load-bearing capacity.

[0044] like Figure 6 As shown, the molded pallet provided in this embodiment is rectangular, preferably slender. The pallet is divided into 20 identical squares according to a 4×5 specification, which can hold up to 20 square goods. This not only makes full use of the pallet size and improves transportation efficiency, but also ensures that when multiple goods are placed on the pallet, the goods are arranged neatly and compactly, resulting in even stress distribution on the pallet and greater stability and safety during transportation.

[0045] It should be noted that the bottom size of the square goods fixed and loaded by the molded tray is same, if different size square goods are fixed, the molded tray provided by the utility model is proportionally enlarged or reduced to fix the square goods of corresponding size.

[0046] Although the utility model discloses as above, the utility model is not limited to this. Any person skilled in the art, without departing from the spirit and scope of the utility model, can make various changes and modifications, therefore the protection scope of the utility model should be limited to the range defined by the claims.
