[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-7 In this embodiment of the present invention, a tire foaming device includes a foaming module 1 and a part-retrieving mechanism 2. The foaming module 1 includes a base frame 11, a bottom mold 12 rotatably mounted on the base frame 11, a rotation drive 13 for driving the bottom mold 12 to rotate, a top frame 14 hinged to the base frame 11, a top mold 15 rotatably mounted on the top frame 14, a mold-locking device 16 for restricting the rotation of the top mold 15 and the bottom mold 12, and an opening and closing drive 17 for driving the top frame 14 to complete mold closing or opening. The mold-locking device 16 includes two arc-shaped clamping plates 161 and a mold-locking drive 162 for driving the two arc-shaped clamping plates 161 to move closer to each other or further away from each other. The part-retrieving mechanism 2 includes an arc-shaped guide rail 21 disposed on the outside of the foaming module 1, a movable seat 22 movably disposed on the arc-shaped guide rail 21, a part-retrieving drive 23 rotatably disposed on the movable seat 22, and a part-retrieving top plate 24 disposed on the protruding end of the part-retrieving drive 23.

[0028] In use, the opening and closing drive component 17 drives the bottom mold 12 and the top mold 15 to close. The operator pours polyurethane foam material into the mold cavity formed by the closed bottom mold 12 and top mold 15. Then, the rotation drive component 13 drives the bottom mold 12 and top mold 15 to rotate, generating centrifugal force to mold the material in the mold cavity into a tire. During this process, the two arc-shaped clamping plates 161 move away from the top mold 15 and bottom mold 12, without restricting their rotation. After foaming, the locking drive component 162 drives the two... The arc-shaped clamping plates 161 move closer to each other to fix the top mold 15 and the bottom mold 12, thereby restricting the rotation of the top mold 15 and the bottom mold 12. Then, the opening and closing drive component 17 drives the bottom mold 12 and the top mold 15 to complete the mold opening. The worker moves the part removal drive component 23 to a suitable position. After reaching the suitable position, the part removal drive component 23 starts to operate, driving the part removal top plate 24 to move and pry out the product in the bottom mold 12. This replaces the traditional method of manually prying out the product with tools, achieving the purpose of saving labor and time.

[0029] The mold-locking drive component 162 includes a cylinder fixing block 163, a first finger cylinder 164, and a second finger cylinder 165. There are two cylinder fixing blocks 163, spaced apart. The first finger cylinder 164 and the second finger cylinder 165 are respectively mounted on the two cylinder fixing blocks 163. The first finger cylinder 164 has a first gripping finger 166 and a second gripping finger 167 facing each other. The second finger cylinder 165 has a third gripping finger 168 and a fourth gripping finger 169 facing each other. One arc-shaped clamping plate 161 has its two ends connected to the first gripping finger 166 and the third gripping finger 168, respectively, and the other arc-shaped clamping plate 161 has its two ends connected to the second gripping finger 167 and the fourth gripping finger 169, respectively. It can be understood that there are two mold-locking devices 16, which are respectively mounted on the base frame 11 and the top frame 14, respectively, to restrict the bottom mold 12 and the top mold 15. During the operation of the mold clamping device 16, the first finger cylinder 164 and the second finger cylinder 165 drive the two arc-shaped clamping plates 161 to move, thereby restricting the top mold 15 and the bottom mold 12.

[0030] Brake bands 1610 are provided on the sides of the two arc-shaped clamping plates 161 that are close to each other. During the operation of the mold clamping device 16, the two arc-shaped clamping plates 161 approach each other, and the resistance generated by the brake bands 1610 causes the rotation speed of the bottom mold 12 and the top mold 15 to decrease rapidly until they stop.

[0031] The movable base 22 includes an adjustable plate 25, a top plate 26 at the bottom of the adjustable plate 25, an oblong hole 226 on the adjustable plate 25, a first bolt 27 passing through the oblong hole 226, a first threaded hole (not shown in the figure) on the top of the top plate 26, the first bolt 27 passing through the oblong hole 226 and threadedly connected to the first threaded hole (not shown in the figure), and side plates 28 on both sides of the top plate 26, each side plate 28 having a first fixing hole 29, a first fixing hole 29 passing through the first fixing hole 29. The second bolt 210 and the top plate 26 both have second threaded holes 211. The second bolt 210 passes through the first fixing hole 29 and is threaded into the second threaded hole 211. The top plate 26 and the side plate 28 both have mounting holes 212. Universal ball bearing rollers 213 are installed in the mounting holes 212. The universal ball bearing rollers 213 roll with the guide rail. The universal ball bearing rollers 213 are equipped with studs 214. The studs 214 pass through the mounting holes 212 and are threaded with nuts 215. In this way, the universal ball bearing rollers 213 reduce the moving resistance of the moving seat 22, thereby saving manpower. The first bolt 27, the second bolt 210, the studs 214 and the nuts 215 facilitate the installation and disassembly of various components. The oblong hole 226 allows the installation position of the top plate 26 on the adjustable plate 25 to be adjusted, increasing practicality.

[0032] Each of the two side plates 28 has a sliding base block 227 on an opposite side. A sliding cavity is formed between the top plate 26, the side plates 28, and the sliding base block 227 to mate with the arc-shaped guide rail 21. A second fixing hole 228 is provided on the side plate 28, and a third bolt 229 passes through the second fixing hole 228. A third threaded hole 230 is provided on the base block, and the third bolt 229 passes through the second fixing hole 228 and is threaded into the third threaded hole 230. The sliding base block 227 prevents the movable seat 22 from falling off the arc-shaped guide rail 21.

[0033] The part-retrieving drive component 23 includes an SC cylinder 216. One end of the SC cylinder 216 has a cylinder fixing plate 217 with a through hole (not shown in the figure). The piston rod of the SC cylinder 216 passes through the through hole (not shown in the figure) and connects to a part-retrieving fixing block 218. A part-retrieving top plate 24 is located at the bottom of the part-retrieving fixing block 218. The part-retrieving fixing block 218 has a third fixing hole (not shown in the figure), and a fourth bolt 219 passes through the third fixing hole (not shown in the figure). The top of the part-retrieving top plate 24 has a fourth threaded hole (not shown in the figure), and the fourth bolt 219 passes through the third fixing hole (not shown in the figure) and is threadedly connected to the fourth threaded hole (not shown in the figure). During part retrieval, the SC cylinder 216 drives the part-retrieving top plate 24 to move, prying the product out of the bottom mold 12. The fourth bolt 219 facilitates the installation and removal of the part-retrieving top plate 24.

[0034] The bottom of the cylinder fixing plate 217 is provided with a connecting block 220, and two rotating blocks 221 are arranged at intervals on the adjustable plate 25. The connecting block 220 is located between the two rotating blocks 221. Both the connecting block 220 and the rotating blocks 221 are provided with shaft holes 222, and a rotating shaft 231 passes through the shaft holes 222. In this way, the SC cylinder 216 can rotate in a vertical plane, which facilitates the operation of picking up parts by the staff.

[0035] The part-retrieving fixing block 218 is provided with a guide rod 223, and the cylinder fixing plate 217 is provided with a guide hole (not shown in the figure) for the guide rod 223 to pass through. The arrangement of the guide rod 223 and the guide hole (not shown in the figure) helps to improve the stability of the movement of the part-retrieving fixing block 218.

[0036] The other end of the SC cylinder 216 is provided with a handle fixing plate 224, and a handle tube 225 is provided on the handle fixing plate 224. When performing the part retrieval operation, the operator can hold the handle tube 225 to perform the part retrieval operation.
