Description

Technical Field

[0001] This invention belongs to the field of storage technology, and in particular relates to a mold storage management system. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. Often called the "mother of industry," it is widely used in industry.

[0003] For example, CN110509244B discloses a highly adaptable mold placement rack for injection molding machines, including a connecting column. Several sets of U-shaped support frames are fixed at equal intervals on the connecting column. The U-shaped support frames have two sets of sliding grooves, and the ends of the U-shaped support frames have rotating grooves. The rotating grooves are connected to the sliding grooves. A sliding plate for placing molds is slidably connected between the two sets of sliding grooves. By setting a sliding plate that can slide and rotate on the U-shaped support frame, it provides certain convenience for workers to place or remove molds. By sliding the sliding column in the sliding groove, the sliding plate can be pulled out from the U-shaped support frame. Then, by rotating the groove, the sliding plate can be rotated at a certain angle, which makes it convenient for workers to place or remove molds. Since molds are heavy in practice, equipment is needed to assist in handling them.

[0004] Based on this, CN114290311B discloses a mold placement rack, including a placement rack vertically supported on the ground and an external frame disposed on one side of the placement rack and vertically raised and lowered. The placement rack includes a frame body and a placement plate horizontally slidably disposed between the frame body and the external frame. The lower end of the placement plate is provided with two rows of pulleys, and the frame body is horizontally provided with a slide rail for the pulleys to abut and roll. The top of the external frame is provided with a support plate to support the sliding of the placement plate. The mold is transferred as a whole by pulling the placement plate with the external frame. This method requires the placement plate holding the mold to be moved as a whole. This method, which uses the action of a tension spring, is not only slow in actual operation, but also inconvenient to put the mold located on the external frame onto the placement rack.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0038] Please see Figure 1 As shown, the present invention is a mold storage management system, including a mold placement rack 400 for storing molds, and a mold lifting vehicle 100 for placing molds on the mold placement rack 400 or unloading molds from the mold placement rack 400.

[0039] like Figure 2 The mold lifting vehicle 100 includes a movable base 1, a column 11 mounted on the upper surface of the movable base 1, and a first linear module 12 mounted on the top of the column 11. A mounting seat 13 is connected to the slider 121 of the first linear module 12. A tray A2 for placing the mold and a gripping and moving mechanism 3 for gripping and moving the mold are mounted on one side of the mounting seat 13. The gripping and moving mechanism 3 is mounted directly above the tray A2.

[0040] Meanwhile, the mold placement rack 400 includes a placement rack body 4 and a tray B5 that is installed on the placement rack body 4;

[0041] In use, the mold is controlled to move between pallet B5 and pallet A2 by gripping and moving mechanism 3.

[0042] Specifically, such as Figure 5 The gripping and moving mechanism 3 includes a robotic arm mounted on a mounting base 13. The end of the robotic arm is connected to a gripping and moving structure. The gripping and moving structure includes a base 31 connected to the robotic arm. Gripping modules that move synchronously relative to each other or in opposite directions are respectively provided on both sides of the base 31. In use, the gripping and moving structure is first moved to directly above the tray B5 by controlling the movement of the robotic arm. Then, the gripping modules are controlled to grip the mold placed on the tray B5. After gripping, the gripping and moving structure is moved to directly above the tray A2. At this time, the gripping modules are controlled again to release the mold.

[0043] In the above, the gripping module provided by the present invention includes an electric telescopic cylinder 32. A row of connecting seats 33 is provided on a base 31 located at the output end of the electric telescopic cylinder 32. A rotating rod 34 is rotatably passed through the row of connecting seats 33. A gripping frame is connected to the rotating rod 34. The gripping frame includes an L-shaped plate 35. L-shaped connecting plates 36 connected to the rotating rod 34 are respectively provided at both ends of the L-shaped plate 35. A connecting rod 37 parallel to the length direction of the rotating rod 34 is also connected between the two L-shaped connecting plates 36. A connecting rod 38 is rotatably connected to the connecting rod 37. One end of the connecting rod 38 is rotatably connected to the output end of the electric telescopic cylinder 32. In the above, when the two electric telescopic cylinders 32 are extended synchronously, the two L-shaped plates 35 move in opposite directions synchronously, that is, the two L-shaped plates 35 unfold to release the mold. When the two electric telescopic cylinders 32 are retracted, the two L-shaped plates 35 move in opposite directions synchronously, that is, the two L-shaped plates 35 retract to prepare for mold gripping.

[0044] In order to facilitate the gripping of the L-shaped plate 35 at the edge of the mold, in this invention, the tray B5 and the tray A2 are respectively configured to include the tray body B and the tray body A, and the tray body B and the tray body A have the same structure.

[0045] The pallet body A includes a base plate 21, and a rectangular hole 211 is provided in the center of the base plate 21. A liftable carrying plate 212 is provided in conjunction with the rectangular hole 211. In use, the gap between the edge of the mold and the upper surface of the base plate 21 is controlled by controlling the lifting of the carrying plate 212, so that the bottom of the L-shaped plate 35 can contact the bottom side edge of the mold, thereby realizing the gripping of the mold.

[0046] Meanwhile, in this invention, such as Figure 4 To facilitate the lifting and lowering of the carrying plate 212, a longitudinal beam 14 is installed on the mounting base 13 directly below the tray A2, and four ejection cylinders 141 are installed on the longitudinal beam 14. A top plate 142 is connected to the end of the ejection cylinder 141 and abuts against the bottom side of the carrying plate 212. The ejection mechanism composed of the top plate 142 and the ejection cylinders 141 can eject the carrying plate 212 from the rectangular hole 211 to a certain height when needed.

[0047] Meanwhile, a second linear module 143 is provided on the upper surface of the longitudinal beam 14 along its length direction, and the ejector cylinder 141 is installed on the slide of the second linear module 143.

[0048] In some possible implementations, such as Figure 6A rectangular frame 28 is connected to the bottom side of the tray body A. One side of the rectangular frame 28 is connected to the mounting base 13 via a fixing rod 29. A support structure consisting of a pair of horizontal bars 201 and a pair of vertical bars 202 is connected to the bottom side of the base plate 21. The two ends of the vertical bars 202 are welded to the rectangular frame 28. A pair of horizontally placed support rods 23 are welded to the outside of the support structure. An elastic damping support structure 24 is connected between the support rods 23 and the carrying plate 212. The elastic damping support structure 24 is used to facilitate the slow descent of the carrying plate 212 when the mold is placed on the carrying plate 212 and the gripping module is removed. At the same time, when the mold is removed from the carrying plate 212, the carrying plate 212 is slowly raised under the action of the elastic damping support structure 24.

[0049] In this invention, such as Figure 7 The elastic damping support structure 24 can be configured to include a rod 241, with damping sleeves 242 at both ends of the rod 241, and a sleeve 243 that cooperates with the damping sleeve 242 is sleeved on the outside of the damping sleeve 242. A spring 244 is connected between the bottom side of the sleeve 243 and the rod 241. By utilizing the damping effect of the damping sleeve 242 and the sleeve 243, the elastic damping support structure 24 is prevented from rapidly elongating and retracting under the action of force.

[0050] In some possible implementations, such as Figure 3 The frame body 4 has two parallel columns 41 and six columns 41. At least one set of support beams 42 is provided between any two adjacent columns 41. The two support beams 42 in the same set are respectively installed on the two adjacent columns 41. At the same time, the two adjacent columns 41 in the same column are connected by connecting beams 401 and scissor-type connecting frames 402. The stability of the overall structure is enhanced by the setting of connecting frames 402 and connecting beams 401.

[0051] A triangular cross-section guide rail 43 is provided on one side of the support beam 42. A set of support beams 42 are fitted with two trays B5. The bottom of the trays B5 is provided with rollers 51 that roll along the length of the guide rail 43. The rollers 51 are waist-shaped wheels. In order to avoid the mutual collision between the trays B5, a protruding limiting part B is provided in the middle of the guide rail 43 to restrict the movement of the rollers 51.

[0052] Meanwhile, to prevent the tray B5 from sliding off the guide rail 43, protruding limiting parts A are provided at both ends of the guide rail 43 to restrict the movement of the roller 51.

[0053] In this invention, the length of the tray B5 is 1 / 4 of the length of the guide rail 43, that is, the range of motion of the tray B5 is 1 / 2 the length of the guide rail 43, and a rough surface is provided on the middle 1 / 2 length of the guide rail 43. This arrangement uses the rough surface to ensure that when the tray B5 moves to the middle position and abuts against the protruding limiting part B, the roller 51 is in complete contact with the rough surface, thus avoiding the situation where the tray B5 automatically slides on the guide rail 43 in the natural state.

[0054] Meanwhile, in this invention, when it is necessary to place the mold on the tray B5 or remove the mold from the tray B5, the tray B5 is first moved to abut against the protruding limiting part A. At this time, there is no other tray B5 directly above or below the tray B5.

[0055] When it is necessary to place the mold on the tray B5, first control the mold lifting vehicle 100 to move to one side of the tray B5, and control the gripping and moving mechanism 3 to grab the mold located on the tray A2 from the carrying plate 212; then control the gripping and moving mechanism 3 to directly put the mold onto the tray B5.

[0056] When it is necessary to remove the mold from the tray B5, the mold lifting vehicle 100 is first moved to one side of the tray B5, and the slide block is moved along the second straight module 143 to directly below the tray B5. At this time, the ejection cylinder 141 is extended, and then the gripping and moving mechanism 3 is directly gripped from the tray B5. Then, the ejection cylinder 141 is retracted, and the gripping and moving mechanism 3 is directly placed onto the tray A2.

[0057] Furthermore, a pair of horizontal bars 201 and a pair of vertical bars 202 form a rectangular frame; a guide member 25 that moves along the corner of the rectangular frame is provided on the four corner sides of the bottom side of the loading plate 212. The end of the guide member 25 is provided with a limiting part 26. The guide member 25 ensures the stable movement of the loading plate 212, and the limiting part 26 prevents the loading plate 212 from being pushed out of the pallet A or pallet B.
