[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a pulp tray bending forming mold, including multiple adjacent lower mold bodies 1, each lower mold body 1 having a side opening 101 on its side wall, and two insertion holes 102 penetrating the lower mold body 1 on the inner wall of the side opening 101, with a limiting component 3 passing through the multiple lower mold bodies 1, and a locking component 4 provided at the end of the limiting component 3, the locking component 4 being located inside the side opening 101, the multiple lower mold bodies 1 being assembled by the locking component 4 and the limiting component 3, the multiple lower mold bodies 1 forming a whole.
[0025] Multiple lower mold bodies 1 can be assembled to form a whole, or the lower mold body 1 can be used independently, making it more versatile and flexible. This design not only meets the production needs of different sizes, but also improves production efficiency and cost control.
[0026] The limiting component 3 includes a limiting plate 31 located inside the side opening 101 and two insert rods 32 fixed to the side wall of the limiting plate 31. The insert rods 32 are set through the insertion hole 102, and the ends of the insert rods 32 extend into the other side opening 101. A limiting hole 321 is opened at the ends of the insert rods 32.
[0027] The locking assembly 4 includes a positioning sleeve 41 and arc-shaped retaining rings 42 fixed at both ends of the positioning sleeve 41. The arc-shaped retaining rings 42 are engaged with the end of the insertion rod 32 to achieve the purpose of initial positioning. The positioning sleeve 41 has a sliding groove 411 inside, and an elastic engaging mechanism is provided inside the sliding groove 411.
[0028] Specifically, the elastic snap-fit mechanism includes a positioning block 43 fixed in the middle of the slide groove 411, and springs 44 fixed on both sides of the positioning block 43. A slider 45 is fixedly connected to one end of the spring 44, and a pin 46 is fixedly connected to the other end of the slider 45. The other end of the pin 46 is movably connected through the arc-shaped snap ring 42.
[0029] When assembling multiple lower mold bodies 1, firstly, the multiple lower mold bodies 1 are joined together adjacently. Then, the insert rod 32 is passed through the insertion hole 102, so that the limiting plate 31 moves to the inside of the side opening 101 and stops. Then, the positioning sleeve 41 is placed in the side opening 101 on the other side, so that the arc-shaped retaining ring 42 is engaged with the end of the insert rod 32. At this time, the slider 45 is released, the spring 44 releases its elastic force, and pushes the slider 45 to move linearly, so that the pin 46 is inserted into the inside of the limiting hole 321, thereby achieving the purpose of locking the insert rod 32, and thus completing the assembly of multiple lower mold bodies 1.
[0030] Multiple lower mold bodies 1 are fixedly mounted on base plates 2 by bolts 5. Multiple through holes 201 are provided on the base plates 2. Threaded holes are provided on the bottom of the lower mold bodies 1. The threaded end of the bolts 5 passes through the through holes 201 and is threaded into the threaded holes.
[0031] The substrate 2 further improves the installation stability of multiple lower mold bodies 1; the substrate 2, as a unified installation platform, can firmly connect multiple lower mold bodies 1 together to form an integral structure.
[0032] Furthermore, the insertion hole 102 is a round hole and the insertion rod 32 is a round rod. This design makes it easier to align and insert the two when connecting them. The shape of the round hole and the round rod allows the stress to be evenly distributed at the connection, avoiding stress concentration and possible damage. The insertion rod 32 and the insertion hole 102 are in a transition fit. The transition fit can provide good assembly accuracy and positioning accuracy, while avoiding assembly difficulties and stress concentration that may be caused by interference fit.
