[0030] Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, or TPU for short, is a material used in footwear production. TPU shoe sole molds typically refer to molds for athletic shoes, beach shoes, slippers, rubber shoes, and other footwear, with athletic shoes being the primary example. Molds are various dies and tools used in industrial production for methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and stretching to obtain the desired products.

[0031] In related technologies, the disassembly and assembly structure of shoe molds is relatively complex and has poor stability, which affects work efficiency and the structural stability of the device.

[0032] To address some of the problems in related technologies, this application provides a TPU shoe sole mold that is easy to disassemble and assemble. When the shoe mold 17 needs to be replaced, simply pull the two side insert rods 122 to pull the insert block 19 out from the inside of the slot 171. This releases the restriction on the shoe mold 17. Then, start the motor 14 to drive the rectangular block 15 to rise, and push the shoe mold 17 up from the inside of the groove 111 through the top plate 16. This makes it easy for the operator to remove the shoe mold 17. Then, place the new shoe mold 17 inside the L-shaped frame 12, and then reset the two side insert blocks 19 to achieve the effect of fixing the shoe mold 17. The device has a simple structure, facilitates the disassembly or installation of the shoe mold 17, and increases work efficiency.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figures 1-5 This application provides a TPU shoe sole mold that is easy to assemble and disassemble, including an installation component 1; the installation component 1 includes: a bracket 11 with a groove 111 on its top; an L-shaped frame 12 symmetrically arranged inside the groove 111; a placement slot 121 opened inside the L-shaped frame 12; insertion rods 122 symmetrically arranged on the L-shaped frame 12; a frame body 13 disposed at the bottom of the bracket 11; a motor 14 disposed inside the frame body 13; and a lead screw 141 disposed at the output of the motor 14. A shaft; a rectangular block 15 is inserted into the inner side of the frame 13 and threadedly connected to the lead screw 141; a top plate 16 is disposed on the top of the rectangular block 15; a shoe mold 17 is disposed on the top of the top plate 16; slot one 171 is symmetrically opened on the shoe mold 17; slot two 172 is symmetrically opened on the bottom of the shoe mold 17; a pull rod 18 is disposed on the L-shaped frame 12 and inserted into the inner side of the placement groove 121; a spring 181 is sleeved on the outer side of the pull rod 18; and a plug 19 is disposed on the outer side of the pull rod 18.

[0035] When the shoe mold 17 needs to be disassembled, first pull the two side rods 122 to compress the spring 181, and pull the insert block 19 out from the inside of the slot 171. This releases the restriction on the shoe mold 17. Then, start the motor 14 through the external power supply to drive the lead screw 141 to rotate, thereby driving the rectangular block 15 threaded to the lead screw 141 to rise. The top plate 16 pushes the shoe mold 17 up from the inside of the groove 111, making it easy for the operator to remove the shoe mold 17. After completion, reset the top plate 16, then place the new shoe mold 17 inside the L-shaped frame 12, and align the slot 2 172 with the rod 122 to limit the shoe mold 17. Then reset the two side insert blocks 19 and insert them into the inside of the slot 171 to achieve the effect of fixing the shoe mold 17. This device has a simple structure, facilitates the disassembly or installation of the shoe mold 17, and increases work efficiency.

[0036] In some embodiments, an auxiliary component 2 is provided on the insertion rod 122, the auxiliary component 2 including a cone 21 disposed on the top of the insertion rod 122.

[0037] A cone 21 is provided at the top of the insertion rod 122. When the insertion rod 122 is connected to the slot 172, the shape of the cone 21 makes it easier for the slot 172 to connect with the insertion rod 122, thus increasing work efficiency.

[0038] In some embodiments, the auxiliary component 2 further includes an anti-slip pad 22 disposed on the outside of the insertion rod 122.

[0039] An anti-slip pad 22 is provided on the outer wall of the insertion rod 122. This increases the friction when the insertion rod 122 mates with the slot 172, making the mating of the insertion rod 122 with the slot 172 more stable and increasing the structural strength of the device.

[0040] In some embodiments, the auxiliary component 2 further includes: inclined slots 23 symmetrically formed on the insert block 19.

[0041] The top and bottom of the insert 19 are symmetrically cut with slanted grooves 23. The curvature of the slanted grooves 23 makes it easier for the insert 19 to mate with the slot 171, thus increasing work efficiency.

[0042] In some embodiments, the insertion rod 122 is threadedly connected to the L-shaped frame 12.

[0043] The insertion rod 122 and the L-shaped frame 12 are connected by threads, so that the top of the L-shaped frame 12 can be removed by screwing, which makes it easier to replace the damaged insertion rod 122 later, thus increasing work efficiency.

[0044] In some embodiments, the rectangular block 15 is connected to the top plate 16 by bolts.

[0045] The rectangular block 15 is bolted to the top plate 16, which makes it easier to remove the top plate 16 for replacement later.

[0046] In some embodiments, the auxiliary component 2 further includes a docking groove 24 formed at the bottom of the top plate 16.

[0047] A mating groove 24 is made at the bottom of the top plate 16. When the top plate 16 is installed later, the mating groove 24 is mated with the rectangular block 15. This can limit the position of the top plate 16 so that it can be fixed with bolts later.

[0048] In some embodiments, the auxiliary component 2 further includes a rubber pad 25 disposed inside the slot 171.

[0049] Rubber pads 25 are symmetrically arranged on opposite sides of the inner side of slot 171. This increases friction and makes the connection between slot 171 and plug 19 more stable, thus increasing the structural stability of the device.
