[0001] The present application relates to the technical field of sole molding equipment, and in particular to a sole molding equipment. Background Art
[0002] Sole molding equipment is a special mechanical device used in the shoemaking industry to process raw materials such as plastic, rubber, polyurethane, etc. into soles through injection molding. The sole molding equipment uses mold molding to achieve efficient and precise manufacturing of the sole structure.

Due to problems such as insufficient material fluidity and too low injection pressure, depressions or voids appear on the surface or inside of the sole, affecting the injection molding yield of the sole. Summary of the Invention
[0005] In order to improve the problem that the fluid spreads upward from the bottom and reduces the yield rate of the sole, the present application provides a sole forming device.

At this time, the movable structure drives the movable rod to move, allowing the sliding block to slide in the sliding groove. In addition, the sliding groove extends along the circumference of the movable groove, so that the sliding block can realize the reversal of the mold, and the mold entrance is located above the receiving groove, so that the material can fall more smoothly during injection molding, and the material can be allowed to settle downward autonomously under the action of gravity, so that the material and the shoe upper are more tightly combined, and it is less likely to have material shortages, thereby improving the yield rate of the sole.

[0009] By adopting the above technical solution, since the stop strip is slidably connected to the mold, the stop block can be located on the side of the mounting plate away from the mold, so that the stop block can limit the mounting plate. In addition, the stop strip abuts against the groove wall of the movable groove, allowing the groove wall of the movable groove to limit the stop strip, thereby reducing the separation of the mounting plate and the mold during the rotation of the mold, thereby allowing the shoe upper to be stably fixed in the receiving groove.

[0012] Optionally, a limit block is provided on the locking inclined surface, and the limit block is elastic; when the stop strip is located on the side of the limit block away from the mold, the stop block is not at a disengagement distance from the mounting plate.
[0013] By adopting the above technical solution, the stop bar is located on the side of the limit block away from the mold, so that the limit block can limit the stop bar from sliding on the locking slope, so that the stop block is located on the disengagement path of the mounting plate, allowing the mounting plate to be smoothly removed or installed on the mold.
[0014] Optionally, the mold is provided with a through hole connected to the receiving groove, and a placement plate is rotatably connected in the through hole; when the placement plate rotates in a direction away from the receiving groove, the through hole is used for demoulding the sole.
[0015] By adopting the above technical solution, the staff rotates the placement plate so that the placement plate can rotate in the direction away from the receiving groove, so that the staff can remove the sole from the receiving groove through perforation, thereby facilitating the demolding operation of the sole.
[0016] Optionally, a stop spring is provided on the stop block, and the stop spring is deformed in a direction away from the stop block; when the stop block is located on the escape path of the mounting plate, the stop spring abuts against the placement plate.
[0017] By adopting the above technical solution, the stop spring is deformed in the direction away from the stop block, and the stop block is located on the disengagement path of the mounting plate, so that the stop spring abuts the placement plate, making the placement plate and the perforated hole wall more secure, and reducing the possibility of external force causing the placement plate to tilt during the sole injection molding process.
[0018] Optionally, a linkage groove is provided on the side of the placement plate, and a linkage hole connected to the linkage groove is provided on the end face of the placement plate. A first linkage bar for inserting into the linkage hole is slidably connected in the linkage groove, and a second linkage bar is slidably connected in the linkage hole. A limiting groove for inserting the second linkage bar is provided on the mold, and the first linkage bar is used to drive the second linkage bar to be inserted into the limiting groove. The first linkage bar is located on the moving path of the stop spring piece; when the stop spring piece abuts against the first linkage bar, the second linkage bar is inserted into the limiting groove, and at this time the placement plate is fixed in the through hole.
[0019] By adopting the above technical solution, the staff slides the installation bar, allowing the stop spring to drive the first linkage bar to move, allowing the first linkage bar to be inserted into the linkage groove, so that the first linkage bar can drive the second linkage bar to slide in the linkage groove, and the second linkage bar can be inserted into the limiting groove, so that the second linkage bar can be located between the mold and the placement plate, realizing mutual fixation between the mold and the placement plate, and reducing the possibility of the placement plate shaking in the mold due to the reversal of the mold.

[0021] By adopting the above technical solution, when the second linkage bar is inserted into the limiting groove, the second linkage bar can drive the linkage block to move. Since the linkage block is located on the inner wall of the sealing ring, the linkage block drives the sealing ring to deform toward one side of the mold, so that the sealing ring can better seal the gap between the placement plate and the perforated hole wall, reducing the possibility of material detaching from the gap between the placement plate and the mold.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The staff places the shoe upper in the receiving groove, and then installs the mounting plate on the mold, so that the mounting plate blocks the receiving groove. At this time, the movable structure drives the movable rod to move, allowing the sliding block to slide in the sliding groove.

DETAILED DESCRIPTION
[0026] The following is combined with Figure 1-6 This application is described in further detail.
[0027] This embodiment discloses a shoe sole forming device. Figure 1 and Figure 2 A sole forming device includes a shell 1, a movable groove 11 is opened on the shell 1, a movable structure 12 is fixedly connected in the movable groove 11, the movable structure 12 includes a movable cylinder, a movable rod 13 is rotatably connected to the driving shaft of the movable cylinder, and the movable rod 13 can rotate along the circumferential direction of the driving shaft of the movable cylinder.
[0028] Reference Figure 2 The movable groove 11 has a sliding groove 111 formed on its wall. The sliding groove 111 extends along the circumference of the movable groove 11 and along its length. The sliding groove 111 is arc-shaped. A sliding block 131 is fixedly connected to the outer surface of the movable rod 13. The sliding block 131 extends perpendicular to the length of the movable rod 13 and slides within the sliding groove 111.
[0029] Reference Figure 2 and Figure 3 The movable rod 13 is fixedly connected to a fixed plate 2, which is fixedly connected to a mold 21 for injection molding a shoe sole. A receiving groove 211 is defined on the surface of the mold 21 for receiving the shoe upper. An inlet 212 is defined on the bottom wall of the receiving groove 211 for injecting material into the receiving groove 211 to form the shoe sole. An injection molding structure is provided within the housing 1, capable of injecting molding into the mold 21.
[0030] Reference Figure 2 and Figure 3 When the moving cylinder is activated, it drives the moving rod 13 out of the moving groove 11. At this time, the sliding block 131 slides in the sliding groove 111, rotating the mold 21 and positioning the receiving groove 211 on the side of the entrance 212 away from the ground, making it easier for workers to install the upper or remove the sole from the mold. Then, the moving cylinder is activated, driving the moving rod 13 back. At this time, the sliding block 131 slides in the sliding groove 111, reversing the mold 21 and positioning the receiving groove 211 on the side of the entrance 212 close to the ground, making it easier for material to be poured into the receiving groove 211 from above.
[0031] Reference Figure 3The mold 21 is provided with a mounting plate 22 that can block the opening of the receiving groove 211. Two locking blocks 23 are fixedly connected to the surface of the fixed plate 2, with the mold 21 positioned between the two locking blocks 23. A locking bevel 231 is fixedly connected to the surface of the locking block 23 away from the fixed plate 2. The distance between the locking bevel 231 and the fixed plate 2 gradually decreases as the locking block 23 approaches the other locking block 23. A limit block 232 is fixedly connected to the surface of the locking bevel 231, and the limit block 232 is elastic.
[0032] Reference Figure 3 A stop bar 233 is slidably connected to the locking bevel 231. A stop block 234 is fixedly connected to the surface of the stop bar 233. A wear-resistant strip 237 is detachably connected to the surface of the stop block 234 away from the locking block 23. A stop groove 235 is defined on the surface of each stop block 234, adjacent to the other stop block 234. The stop groove 235 receives the mounting plate 22. The limit block 232 is located in the sliding path of the stop bar 233. When the stop bar 233 is located on the side of the limit block 232 away from the mold 21, the stop block 234 does not restrict the movement of the mounting plate 22. When the stop bar 233 is located on the side of the limit block 232 close to the mold 21, the mounting plate 22 and the mold 21 are positioned within the stop groove 235.
[0033] Reference Figure 2 and Figure 3 When the mold 21 is located on the side of the fixed plate 2 away from the ground, the stopper strip 233 can slide along the locking bevel 231, allowing the mounting plate 22 to be located in the stopper groove 235. The stopper block 234 secures the mounting plate 22, reducing the possibility of the shoe upper detaching from the mold 21. When the mold 21 rotates in the movable groove 11, the anti-wear strip 237 and the fixed plate 2 both abut against the groove wall of the movable groove 11, that is, the groove wall of the movable groove 11 restricts the stopper strip 233 from sliding on the locking bevel 231.
[0034] Reference Figure 4 A through-hole 213 is formed on the side of the mold 21, connecting to the receiving groove 211. The through-hole 213 extends to the end face of the mold 21 away from the fixing plate 2. A placement plate 24 is rotatably connected to the through-hole 213. The placement plate 24 can block the opening of the through-hole 213. When the placement plate 24 is rotated, the placement plate 24 no longer blocks the through-hole 213, allowing the sole to be removed from the mold.
[0035] Reference Figure 5A stop spring 236 is fixedly connected to the surface of the stop block 234, and the stop spring 236 is deformed toward the surface close to the fixed plate 2. Two linkage grooves 241 are provided on the side surface of the placement plate 24, and two linkage holes 242 are provided on the end surface of the placement plate 24 away from the fixed plate 2. The two linkage holes 242 are connected to different linkage grooves 241 respectively, and the stop spring 236 can be inserted into the linkage holes 242. A first linkage bar 243 is slidably connected to the linkage groove 241, and a second linkage bar 244 is slidably connected to the linkage hole 242, and the second linkage bar 244 can be inserted into the linkage groove 241. A limiting groove 245 is provided on the wall of the through hole 213 for the first linkage bar 243 to be inserted. When the first linkage bar 243 is inserted into the limiting groove 245, the placement plate 24 is fixed to the mold 21.
[0036] Reference Figure 4 and Figure 5 A first magnet 246 is fixedly connected to the bottom wall of the limiting groove 245, and a second magnet 247 is fixedly connected to the end surface of the first linkage bar 243. The first magnet 246 repels the second magnet 247. A linkage slope 248 is provided on the surface of the first linkage bar 243. The distance between the linkage slope 248 and the fixed plate 2 gradually increases from the second linkage bar 244 to the other second linkage bar 244, and the linkage slope 248 is located on the movement path of the second linkage bar 244.
[0037] Reference Figure 5 When the stop spring piece 236 is inserted into the linkage hole 242, the stop spring piece 236 drives the first linkage bar 243 to move, allowing the second linkage bar 244 to be inserted into the linkage groove 241. The first linkage bar 243 drives the first linkage bar 243 to move through the linkage inclined surface 248, allowing the first linkage bar 243 to be inserted into the limiting groove 245, thereby fixing the placement plate 24 on the mold 21.
[0038] Reference Figure 3 and Figure 6 The placement plate 24 is provided with an annular groove 25, within which a sealing ring 251 is located. A through-hole is formed in the wall of the annular groove 25, connecting to the linkage groove 241. A linkage block 252 is fixedly connected to the first linkage bar 243. The linkage block 252 extends along the length of the placement plate 24 and slides within the through-hole. When the placement plate 24 completely blocks the through-hole 213, the sealing ring 251 can block the gap between the placement plate 24 and the wall of the through-hole 213. At this time, the linkage block 252 is located on the inner wall of the sealing ring 251.
[0039] Reference Figure 3 、 Figure 5 and Figure 6When the first linkage bar 243 is inserted into the limiting groove 245, the first linkage bar 243 drives the linkage block 252 to abut against the sealing ring 251, which in turn drives the sealing ring 251 to protrude from the placement plate 24, thereby enabling the sealing ring 251 to seal the gap between the placement plate 24 and the wall of the through-hole 213. When the first linkage bar 243 is removed from the limiting groove 245, the linkage block 252 no longer abuts against the sealing ring 251, and the sealing ring 251 returns to the annular groove 25, facilitating the rotation of the placement plate 24.
[0040] The implementation principle of a sole molding device in an embodiment of the present application is as follows: the staff first installs the upper in the receiving groove 211, and blocks the opening of the receiving groove 211 with the mounting plate 22, and then the staff slides the stop bar 233 so that the mounting plate 22 can be located in the stop groove 235, and finally the staff starts the moving cylinder, and the moving cylinder drives the moving rod 13 to move, allowing the sliding block 131 to slide in the sliding groove 111, thereby realizing the reversal of the mold 21 to facilitate injection molding of the sole.
