Abstract
Description
Technical Field
[0001] This application relates to the technical field of shoe sole processing, and in particular to a demolding and positioning mechanism for shoe sole processing. Background Technology
[0002] Shoe soles are an essential part of our daily lives. The manufacturing process of shoe soles usually uses a disc machine. The disc machine has a disc with multiple molds arranged in a ring on it. The molds include an upper mold and a lower mold. The upper mold is set on the lower mold and the upper mold and the lower mold are fixed together by a locking mechanism. The shoe sole needs to complete injection molding, cooling and demolding steps on the disc machine.
[0003] The demolding and positioning mechanism includes a frame, on which a lifting mechanism is provided. The lifting mechanism is used to raise the locking mechanism to unlock the upper and lower molds.
[0004] After the sole is injection molded, the demolding and positioning mechanism on the disc machine needs to open the mold and remove the sole. Since the disc machine does not fix the lower mold, if the upper mold is opened with force, the upper mold may move along with the lower mold, thus affecting the demolding process of the sole. Utility Model Content
[0005] In order to improve the situation where the lower mold is prone to movement during the demolding process of shoe soles, this application provides a demolding positioning mechanism for shoe sole processing.
[0006] This application provides a demolding and positioning mechanism for shoe sole processing, which adopts the following technical solution: A demolding and positioning mechanism for shoe sole processing includes a frame with a lifting mechanism for raising a locking mechanism to unlock the upper and lower molds. A pressure plate is provided on the frame and is located above a disc. When the mold rotates to below the pressure plate, the pressure plate is located on the movement path of the lower mold as it disengages from the disc.
[0007] By adopting the above technical solution, when the mold rotates to the bottom of the pressure plate, the pressure plate is located on the movement path of the lower mold detaching from the disc. The pressure plate can block the lower mold, restricting the lower mold between the pressure plate and the disc, reducing the possibility of the upper mold driving the lower mold to move, thereby ensuring the repeatability accuracy of each mold closing, so as to better realize the demolding of the shoe sole.
[0008] Optionally, the frame is provided with multiple limiting holes, and each of the multiple limiting holes is slidably connected to a limiting strip. Adjacent limiting strips abut against each other, and the limiting strips are used to seal the gap between the pressure plate and the mold. When the mold rotates to the position below the pressure plate, the multiple limiting strips are located between the pressure plate and the mold.
[0009] By adopting the above technical solution, due to industrial errors between the pressure plate and the mold, there is often a gap between the pressure plate and the mold. By providing multiple limiting holes on the frame, and slidably connecting limiting strips in each limiting hole, the mold can push the limiting strips on the moving path back into the limiting holes. The remaining limiting strips are located between the pressure plate and the mold, and adjacent limiting strips abut against each other to seal the gap between the pressure plate and the mold, thereby fixing the pressure plate and the mold and reducing the possibility of mold movement.
[0010] Optionally, the limiting strip is provided with a guide slope, and the distance from the guide slope to the disk gradually decreases along the direction of the disk approaching the frame. The guide slope is used to guide the limiting strip to move in the direction of insertion into the limiting hole.
[0011] By adopting the above technical solution, the distance from the guide slope to the disk gradually decreases along the direction of the disk approaching the frame, so that the limiting strip can move in the direction of insertion into the limiting hole along the inclined direction of the guide slope, which is beneficial for the mold to push the limiting strip into the limiting hole.
[0012] Optionally, the frame is provided with a first magnet, and each of the plurality of limiting strips is provided with a second magnet, wherein the first magnet and the second magnet repel each other.
[0013] By adopting the above technical solution, the first magnet and the second magnet repel each other, and the first magnet can apply a repulsive force to multiple limiting strips, so that the first magnet can drive multiple limiting strips to move away from the first magnet, reducing the possibility of the limiting strips being inserted into the limiting hole during the operation of the equipment.
[0014] Optionally, the frame is provided with a receiving groove, which is connected to a plurality of limiting holes, and the first magnet is slidably connected in the receiving groove.
[0015] By adopting the above technical solution, when the staff needs to install the limiting strip, the first magnet is slidably connected in the receiving groove. The staff first slides the first magnet open, then installs the limiting strip into the limiting hole, and then slides the first magnet to seal the limiting hole, so as to realize the installation of the limiting strip.
[0016] Optionally, the receiving groove has a resilient locking block on its wall, and the locking block is located on the moving path of the first magnet; when the first magnet comes into contact with the surface of the locking block away from the ground, the first magnet disengages from the moving path of the multiple limiting strips.
[0017] By adopting the above technical solution, when the staff needs to install the limit strip, the staff slides the first magnet to the side of the block away from the ground, so that the block can prevent the first magnet from moving towards the ground, thus facilitating the installation of the limit strip.
[0018] Optionally, the limiting strip is provided with a protrusion, and the wall of the limiting hole is provided with a fixing groove for the protrusion to be inserted, the fixing groove extending along the length direction of the limiting hole.
[0019] By adopting the above technical solution, a fixing groove for inserting a protrusion is provided on the wall of the limiting hole, and the fixing groove extends along the length direction of the limiting hole, so that the protrusion can slide in the fixing groove to restrict the limiting strip from detaching from the limiting hole, allowing the limiting strip to slide stably in the limiting hole and reducing the possibility of the limiting strip detaching from the limiting hole.
[0020] Optionally, the pressure plate is provided with a sponge component, which is used to buffer the impact between the mold and the pressure plate.
[0021] By adopting the above technical solution, a sponge component is provided on the pressure plate, which can buffer the impact between the mold and the pressure plate, protect the limit strip, reduce the possibility of damage to the limit strip, and thus extend the service life of the equipment.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the mold rotates to the bottom of the pressure plate, the pressure plate is located on the movement path of the lower mold as it leaves the disc. The pressure plate can block the lower mold and restrict it between the pressure plate and the disc, reducing the possibility of the upper mold driving the lower mold to move. This ensures the repeatability accuracy of each mold closing and better achieves the demolding of the shoe sole.
[0023] 2. Due to industrial tolerances between the pressure plate and the mold, there is often a gap between them. The frame has multiple limiting holes, and each limiting hole is slidably connected to a limiting strip. The mold can push the limiting strip on the moving path back into the limiting hole. The remaining limiting strip is located between the pressure plate and the mold, and adjacent limiting strips abut against each other to seal the gap between the pressure plate and the mold, thus fixing the pressure plate and the mold and reducing the possibility of mold movement.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.
[0027] Example 1 This embodiment discloses a demolding and positioning mechanism for shoe sole processing. (Refer to...) Figure 1 A demolding and positioning mechanism for shoe sole processing includes a frame 1, on which a lifting mechanism 11 is provided. The lifting mechanism 11 includes a first lifting plate 111 and a second lifting plate 112. The second lifting plate 112 has a placement hole 113 for inserting the first lifting plate 111, and the second lifting plate 112 is arranged around the first lifting plate 111. A drive assembly 12, which is a cylinder, is fixedly connected to the surface of both the first lifting plate 111 and the second lifting plate 112 near the ground. The drive assembly 12 is used to drive the first lifting plate 111 and the second lifting plate 112 to lift or lower away from the ground. The first lifting plate 111 and the second lifting plate 112 are used to lift a locking mechanism to separate the upper mold and the lower mold.
[0028] Reference Figure 1 A pressure plate 2 is fixedly connected to the surface of the frame 1 near the disc, and the pressure plate 2 is located above the disc. Multiple molds are arranged in a circumferential array along the disc, and as the disc rotates, they are positioned directly below the pressure plate 2. The pressure plate 2 includes a first connecting part 21 and a second connecting part 22. Two first connecting parts 21 are provided, both fixedly connected to the surface of the frame 1 near the disc. The second connecting part 22 is fixedly connected between the two first connecting parts 21 and is used to abut against the lower mold. When the mold rotates to a position below the pressure plate 2, the pressure plate 2 is positioned on the moving path of the lower mold's lifting motion.
[0029] The implementation principle of Example 1 is as follows: When the mold rotates to the bottom of the pressure plate 2, the lower mold is located between the pressure plate 2 and the disc. The first lifting plate 111 and the second lifting plate 112 are raised in sequence to lift the locking mechanism so as to unlock the upper mold and the lower mold. During the process of taking out the shoe sole, the pressure plate 2 can prevent the lower mold from detaching from the disc.
[0030] Example 2 Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that multiple limiting holes 13 are provided on the surface of the frame 1 near the disc, and the multiple limiting holes 13 are arranged in an array along the vertical direction. Each of the multiple limiting holes 13 is slidably connected to a limiting strip 14, the multiple limiting strips 14 extend out of the limiting holes 13 and adjacent limiting strips 14 abut against each other, the multiple limiting strips 14 can seal the gap between the pressure plate 2 and the mold.
[0031] Reference Figure 3 Because there is a gap between the pressure block and the lower mold, when the mold rotates to below the pressure plate 2, the lower mold can push the limiting strip 14 located on the lower mold movement path back into the limiting hole 13. The remaining multiple limiting strips 14 are all located between the pressure plate 2 and the lower mold. The multiple limiting strips 14 can block the gap between the pressure plate 2 and the lower mold, thereby reducing the possibility of the lower mold moving during the mold opening process.
[0032] Reference Figure 4 A guide slope 141 is provided on the surface of the limiting strip 14 away from the limiting hole 13. The distance from the guide slope 141 to the disk gradually decreases along the direction of the disk approaching the frame 1. When the lower mold abuts against the limiting strip 14, the lower mold can push the limiting strip 14 back into the limiting hole 13 along the inclined direction of the slope.
[0033] Reference Figure 5 The outer surfaces of the limiting strip 14 on both sides opposite to each other are fixedly connected with protrusions 142. The walls of the limiting holes 13 on both sides opposite to each other are provided with fixing grooves 131 for the protrusions 142 to be inserted. The fixing grooves 131 extend along the length of the limiting hole 13 and can restrict the limiting strip 14 from detaching from the limiting hole 13.
[0034] Reference Figure 6 The frame 1 has a receiving groove 15, which is connected to multiple limiting holes 13. A first magnet 151 is slidably connected inside the receiving groove 15, and a slot 153 for inserting the first magnet 151 is provided on the groove wall of the receiving groove 15 near the ground.
[0035] Reference Figure 6 Each of the multiple limiting strips 14 has a second magnet 143 fixedly connected to its end face near the first magnet 151. The second magnet 143 and the first magnet 151 repel each other, and the first magnet 151 can move the limiting strip 14 away from the first magnet 151 through the second magnet 143.
[0036] Reference Figure 6A resilient locking block 152 is fixedly connected to the wall of the receiving groove 15, and the locking block 152 is located on the movement path of the first magnet 151. When the first magnet 151 is located on the side of the locking block 152 away from the ground, the locking block 152 restricts the first magnet 151 from moving towards the ground. At this time, the first magnet 151 is disengaged from the movement path of the multiple limiting strips 14, making it easier for the staff to install the limiting strips 14 in the limiting holes 13.
[0037] Reference Figure 4 A sponge component 23 is fixedly connected to the surface of the pressure plate 2 near the limit rod. The sponge component 23 is used to buffer the impact between the mold and the pressure plate 2.
[0038] The implementation principle of Example 2 is as follows: When the mold rotates to the bottom of the pressure plate 2, the mold pushes the abutting limit strip 14 back into the limit hole 13 along the inclined direction of the guide slope 141. The remaining limit strips 14 are located between the pressure plate 2 and the lower mold to seal the gap between the pressure plate 2 and the lower mold.
