Detailed implementation manners

[0015] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0016] As Figure 1-4 shown, the present invention provides a four-way opening fork-in tray mold, which sequentially includes a base 1, a lower die holder 2 and an upper die holder 3 from bottom to top. A support plate 5 is connected to the periphery of the base 1 through a support member, and a plurality of support columns are further provided between the base 1 and the support plate 5. A demolding mechanism is provided between the base 1 and the support plate 5. The lower die holder 2 is installed on the support plate 5. The lower die holder 5 includes a die frame 6 and a lower die 7 provided on the die frame 6. A die pressing groove 8 is formed on the lower die 7, and the die pressing groove 8 is distributed in a "Sichuan" shape on the lower die 7. The die pressing groove 8 extends upward from its lower end face in a stepped shape to improve the bending resistance of the supported legs extruded out; two groups of symmetrically arranged first extrusion blocks 9 are fixedly connected to the inner walls on both sides of the die pressing groove 8. The upper die holder 3 includes an upper template 4 and an upper die 10 installed at the bottom of the upper template 4. A punch core 11 adapted to the die pressing groove 8 is provided at the bottom of the upper die 10. Second extrusion blocks 12 corresponding to the first extrusion blocks 9 are fixedly connected to the two side walls of the punch core 11.

[0017] As Figure 1-4As shown, the base 1 and the support member, and the support member and the support plate 5 are all installed by bolts, which can be easily disassembled. In this embodiment, the support member includes a support plate arranged around the base 1 and a support column arranged on the base 1. The lower mold 7 and the mold frame 6 are also fixed by bolts. By replacing different lower molds 7, it can be used for the production of molds of molded pallets of different shapes. It has a wide range of applications, strong adaptability, and is suitable for promotion. In the utility model, the upper mold 10 and the lower mold 7 cooperate to extrude the plate surface of the pallet, the molded groove 8 and the convex mold core 11 cooperate to extrude the supporting feet of the pallet, and the extrusion block 1 9 and the extrusion block 2 12 are mutually By cooperating, a fork hole for inserting a forklift can be squeezed out. When in use, the stirred blank is spread in the mold frame 6, and then pressure is applied to the upper mold base 3, so that the punch core 11 at the bottom of the upper mold 10 falls into the corresponding mold groove 8. During the extrusion process, the extrusion blocks 2 12 on both sides of the punch core 11 extrude the blank on the side of the extrusion block 1 9 in the mold groove 8 to form a fork hole. The utility model does not require manual hole drilling, which ensures that the produced fork holes correspond one to one, improves product quality, and can meet mass production. The extruded pallet can be forked through the fork hole or through the gap between two adjacent support legs to meet the four-way fork requirement.

[0018] The extrusion block 1 9 and the extrusion block 2 12 are both triangular prism structures, so that the extruded hole is a rectangular structure, which can be used in conjunction with the fork of a forklift.

[0019] like Figure 3 and 4 As shown, the shapes and sizes of the extrusion block 1 9 and the extrusion block 2 12 are the same, the side edges of the extrusion block 1 9 are facing upward, and the side faces of the extrusion block 2 12 are facing upward, so that when the extrusion block 1 9 and the extrusion block 2 12 are used in conjunction with each other, they can achieve the function of close contact and extrude all the blanks between them.

[0020] A plurality of push holes 13 are provided at the bottom of the molding groove 8, a push hole 2 14 corresponding to the push hole 13 is provided on the support plate 5, the demoulding mechanism includes a demoulding plate 15, a hydraulic cylinder, a plurality of guide columns 16 and a plurality of push rods 17 corresponding to the push hole 13, the push rods 17 are evenly arranged on the demoulding plate 15, the guide columns 16 are evenly arranged on the base 1, the demoulding plate 15 is slidably arranged on the guide columns 16, the hydraulic cylinder is arranged in the middle of the base 1, the protruding end of the hydraulic cylinder is connected to the bottom of the demoulding plate 15, and the push rod 17 is always in the push hole 13.

[0021] like Figure 2As shown, before the blank is laid into the mold frame 6, the output end of the push rod 17 is always in the push hole 13, and its end is just in the same plane with the bottom surface of the molding groove 8, to prevent the blank from squeezing out of the push hole 13 when the blank is extruded; the guide column 16 plays a role in stabilizing the lifting and lowering. When the extrusion is completed and the mold needs to be demolded, the hydraulic cylinder is started to drive the demolding plate 15 to move along the guide column 16 toward the lower mold 7, and drive the push rod 17 to push out the formed tray to complete the automatic demolding.

[0022] The punch core 11 is connected to the upper mold 10 by bolts, and the top of the upper mold plate 4 is detachably mounted with an extrusion plate 18 through a plurality of connecting plates and connecting columns. Guide columns 19 are provided at the four corners of the base 1, and the extrusion plate 18 is slidably mounted on the guide columns 19.

[0023] like Figure 2 As shown, the punch core 11 is detachably mounted on the upper mold 10 by bolts. By removing or replacing the punch core 11 and cooperating with the lower mold 7 matched with the upper mold 10, pallets with different shapes of plate surfaces can be obtained. The extrusion plate 18 drives the upper mold 7 to be slidably mounted on the guide column 19. The blank is extruded through a stamping mechanism on the top of the extrusion plate 18. The stamping mechanism can be a hydraulic cylinder. The output end of the hydraulic cylinder is connected to the top of the extrusion plate 18 to drive the upper mold 10 to move in the direction of the lower mold 7. When different pallets need to be produced, only different upper molds 10 and lower molds 7 need to be replaced. The same molding device can be suitable for the production of different molded pallets.

[0024] Principle of use: During production, spread the stirred blank into the mold frame 6, and then apply pressure to the upper mold base 3, so that the punch core 11 at the bottom of the upper mold 10 falls into the corresponding molding groove 8. During the extrusion process, the extrusion blocks 2 12 on both sides of the punch core 11 extrude the blank on the side of the extrusion block 1 9 in the molding groove 8 to form a fork hole. After the extrusion is completed, the hydraulic cylinder is driven to start, drive the stripping plate 15 to move along the guide column 16 toward the lower mold 7, and drive the push rod 17 to push out the formed tray to complete the automatic demolding.

[0025] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
