Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of shoe sole production, and particularly relates to a foamed shoe sole one-time forming device and process. BACKGROUND
[0002] Foamed shoe soles are widely used in sports shoes, leisure shoes and other products due to their light weight, wear resistance, excellent elasticity and other characteristics, and the forming quality of the foamed shoe soles directly determines the wearing comfort and service life of the shoes. At present, the mainstream foamed shoe sole forming process in the industry adopts a mold pressing foaming technology, that is, the foaming material is injected into a mold cavity, and the forming is completed after heating, foaming, and cooling and solidification.
[0003] During the filling and foaming of the foaming material in the mold, problems such as uneven material flowability and air attachment on the inner wall of the mold may cause bubbles to remain in the side wall, bottom or inside of the material in the mold cavity. The traditional equipment lacks a targeted defoaming mechanism and only relies on the flowability of the material itself or a simple mold vent to exhaust air, which is difficult to completely break the micro-bubbles attached to the inner wall of the mold. These residual bubbles may cause defects such as material shortage, depression, pinholes and the like on the surface of the formed shoe sole, which not only affects the appearance of the product, but also reduces the structural strength of the shoe sole, causing it to crack easily during use and significantly increasing production costs. When the foaming material foams in the mold cavity, part of the material will overflow the mold closing gap to form a flash, and the existing process needs to be processed twice after the shoe sole is formed and demolded, through manual trimming or a separate flash equipment. Manual trimming has problems such as low precision, poor consistency, high labor intensity, and is easy to damage the edge structure of the shoe sole. SUMMARY

These terms are only used to distinguish the first element from another element.
[0044] As Figures 1 to 7As shown, in one embodiment, a foaming shoe sole one-shot forming equipment is proposed, comprising an equipment body 1, a bottom die 2 and a top die 5, the bottom die 2 is fixedly connected to the bottom of the inner cavity of the equipment body 1, the top die 5 is slidingly connected to the inside of the equipment body 1 and is located above the bottom die 2, further comprising:
[0045] A rotating assembly 3 is arranged in the inside of the equipment body 1, the rotating assembly 3 is used for uniformly distributing the foaming material in the inside of the bottom die 2, the rotating assembly 3 comprises a cover plate 31 rotatably connected to the top of the bottom die 2, a motor 32 is installed in the inside of the bottom die 2 and is located below the cover plate 31, a magnetic plate 33 is fixedly connected to the top of the motor 32 and is magnetically coupled with the cover plate 31, limit frames 34 are uniformly fixedly connected to the outer wall of the motor 32, sliding blocks 35 are slidingly connected in the inside of the limit frames 34, third sliding rods 36 are slidingly connected in the inside of the sliding blocks 35, first springs 37 are fixedly connected between the third sliding rods 36 and the sliding blocks 35, a guide ring 38 is fixedly connected to the bottom of the inner cavity of the bottom die 2, and the bottom of the third sliding rod 36 is slidingly fitted in the inside of the guide ring 38.
[0046] A flash assembly 4 is arranged in the inside of the equipment body 1 and is used for flash forming the edge of the formed shoe sole.
[0047] A defoaming assembly 6 is arranged in the inside of the top die 5 and is used for defoaming after the foaming material in the inside of the bottom die 2 is filled.
[0048] In actual application, the staff operates the equipment to pour the foaming liquid into the bottom die 2, and then starts the motor 32, the motor 32 rotates to drive the cover plate 31 to rotate through the magnetic coupling of the magnetic plate 33 and the cover plate 31, and the cover plate 31 flows the foaming material in the inside of the bottom die 2 to the edge in the rotating process, so that the foaming material is uniformly spread in the inside of the bottom die 2, and the inside of the bottom die 2 is completely filled when the foaming material foams in the inside of the bottom die 2.
[0049] In the process of driving the limit frame 34 to rotate together, the third sliding rod 36 is limited by the guide ring 38, and drives the sliding block 35 to reciprocate in the inside of the limit frame 34, in the process of revolving around the motor 32, the bottom of the third sliding rod 36 is continuously extruded to make the first spring 37 elastically contract, when the rotating assembly 3 is no longer extruded, the first spring 37 rebounds, the third sliding rod 36 knocks the bottom of the bottom die 2, through the limitation of the guide ring 38 to the third sliding rod 36, the third sliding rod 36 can uniformly knock the bottom of the bottom die 2, the bubbles attached to the inner wall of the bottom die 2 in the foaming material are separated from the inner wall of the bottom die 2 and float upward under the action of the knocking vibration of the third sliding rod 36, so that the problem that the surface of the formed shoe sole is not fully foamed and has a gap due to the bubbles attached to the inner wall of the bottom die 2 in the foaming process is avoided.
[0050] As Figure 7As shown, in a preferred embodiment of the present invention, a first slide rod 3101 is symmetrically slidably connected inside the cover plate 31, a second spring 3102 is fixedly connected between the first slide rod 3101 and the inner wall of the cover plate 31, and brush strips 3103 are fixedly connected in a ring array on the outer wall of the first slide rod 3101.
[0051] In practical application, during the rotation of the cover plate 31, the first slide rod 3101 slides outwards from the rotating assembly 3 due to centrifugal force, and the second spring 3102 stretches elastically as the first slide rod 3101 slides out. After the first slide rod 3101 slides out of the cover plate 31, the brush strip 3103 is no longer limited by the inner cavity of the cover plate 31 and spreads out in an umbrella shape. During the rotation of the first slide rod 3101 and the brush strip 3103 with the cover plate 31, the brush strip 3103 scrapes the surface of the bottom mold 2, thereby ensuring that no air bubbles adhere to the inner wall of the bottom mold 2, thus improving the quality of the product after foaming and molding.
[0052] like Figures 8 to 11 As shown, in another preferred embodiment of the present invention, a carrier plate 41 is slidably connected to the bottom of the top mold 5, a rack 42 is fixedly connected inside the main body 1, the carrier plate 41 and the rack 42 are slidably engaged, a toothed plate 43 is symmetrically rotatably connected to the middle of the carrier plate 41, a slide plate 44 is slidably connected inside the toothed plate 43, a third spring 45 is installed between the side wall of the slide plate 44 and the outer wall of the carrier plate 41, a hot melt head 46 is installed on the end side of the slide plate 44, a roller 47 is symmetrically rotatably connected to the side wall of the hot melt head 46, a bevel gear shaft 48 is rotatably connected to the carrier plate 41, a first toothed shaft 49 meshing with the bevel gear shaft 48 is rotatably connected to the upper surface of the carrier plate 41, a second toothed shaft 411 is rotatably connected to the side of the carrier plate 41 near the inner wall of the main body 1, a fourth spring 410 is fixedly connected between the second toothed shaft 411 and the first toothed shaft 49, and a toothed groove 412 meshing with the second toothed shaft 411 is opened on the side wall of the main body 1.
[0053] In practical application of this invention, after the foaming material is foamed and formed inside the bottom mold 2, the top mold 5 will be lifted upward inside the main body 1 of the equipment. After the top mold 5 moves upward, it will drive the carrier plate 41 to move together. After the carrier plate 41 moves upward, the toothed plate 43 will mesh with the outer wall of the rack 42 and flip, so that the toothed plate 43 flips from a vertical state to a horizontal state. After the toothed plate 43 flips to a horizontal state, the compressed third spring 45 extends and pushes the slide plate 44 to slide outward inside the toothed plate 43.
[0054] When the carrier plate 41 moves upwards, the second pinion shaft 411 moves upwards, and the second pinion shaft 411 meshes with the gear slot 412 and rotates. During the rotation of the second pinion shaft 411, the first pinion shaft 49 cannot rotate because the bevel gear shaft 48 is still inside the bottom die 2 and meshes with the bevel gear shaft 48. Therefore, the fourth spring 410 is twisted and generates a torsion force after the rotation of the second pinion shaft 411. When the bevel gear shaft 48 completely slides out of the bottom die 2, the torsion force of the fourth spring 410 is released, and the bevel gear shaft 48 is rotated through the first pinion shaft 49.
[0055] After the bevel gear shaft 48 moves upwards, the formed sole is lifted and demolded from the inside of the bottom die 2. When the bevel gear shaft 48 completely separates from the inside of the bottom die 2, the sole rotates above the bottom die 2. At this time, the hot melting head 46 performs a flash on the edge of the formed sole, so that the formed sole does not need to be taken off by the staff for flash operation, simplifying the operation process of the staff.
[0056] As shown in Figure 11 , as another preferred embodiment of the present application, the top of the bevel gear shaft 48 is fixedly connected with a sliding frame 481, the sliding frame 481 is slidingly fitted in the inside of the bottom die 2, the side wall of the sliding frame 481 is symmetrically slidingly connected with a side plate 482, the sixth spring 483 is fixedly connected between the side plate 482 and the sliding frame 481, the top plate 484 is rotatably connected to the top of the side plate 482, the seventh spring 485 is fixedly connected between the top plate 484 and the side plate 482, the side wall of the top plate 484 is fixedly connected with a first positioning rod 486, and the inside of the sliding frame 481 is provided with a positioning groove 487 slidingly fitted with the first positioning rod 486.
[0057] When the bevel gear shaft 48 moves upwards and drives the sliding frame 481 to slide out of the inside of the bottom die 2, the sixth spring 483 elastically stretches and pushes the side plate 482 to slide away from the sliding frame 481. When the side plate 482 slides, the top plate 484 also slides horizontally, the first positioning rod 486 on the side wall of the top plate 484 slides in the positioning groove 487, the top plate 484 is flipped on the top of the side plate 482, the top plate 484 is lifted outward during the horizontal movement of the side plate 482, and the top plate 484 can be inserted into the bottom of the formed sole. After the two side plates 484 are inserted into the sole, the sole is fixed, the sole remains stable on the bevel gear shaft 48 and rotates with the bevel gear shaft 48.
[0058] As shown in Figure 11 , as another preferred embodiment of the present application, the bottom of the side plate 482 is inclined, the side wall of the side plate 482 is fitted with the inner wall of the bottom die 2 inside the bottom die 2, and the bottom of the top plate 484 is serrated.
[0059] As shown in Figure 13 and Figure 14As shown, in another preferred embodiment of the present invention, the defoaming component 6 includes U-shaped air grooves 61 symmetrically formed inside the top mold 5. One end of the U-shaped air groove 61 is slidably connected to a lead screw 62. A fifth spring 63 is fixedly connected between the lead screw 62 and the top mold 5. The other end of the U-shaped air groove 61 is slidably connected to a second slide rod 66. A pressure plate 64 is fixedly connected to the bottom of the second slide rod 66. An injection pipe 65 is connected to the middle of the pressure plate 64. A camshaft 67 is rotatably connected inside the top mold 5. The camshaft 67 and the lead screw 62 are slidably engaged. A striking block 68 is rotatably connected inside the top mold 5. A second positioning rod 69 that slidably engages with the camshaft 67 is fixedly connected to the side of the striking block 68 near the camshaft 67. The end of the striking block 68 abuts against the side wall of the pressure plate 64.
[0060] In practical application, during the process of the top mold 5 moving down to close with the bottom mold 2, the lead screw 62 is squeezed into the top mold 5 by the bottom mold 2. The fifth spring 63 is passively stretched during the movement of the lead screw 62. During the movement of the lead screw 62 into the top mold 5, the air inside the U-shaped air groove 61 is squeezed. The air pressure inside the U-shaped air groove 61 pushes the second slide rod 66 to make the pressure plate 64 slide into the bottom mold 2. After the pressure plate 64 is pressed down, it will contact the surface of the foamed material inside the bottom mold 2, thereby breaking the bubbles on the surface of the foamed material.
[0061] As the lead screw 62 slides into the top mold 5, it drives the camshaft 67 to rotate inside the top mold 5. When the camshaft 67 rotates, it slides on its surface through the second positioning rod 69, causing the striking block 68 to repeatedly strike the side wall of the pressure plate 64 inside the top mold 5. This causes the pressure plate 64 to be in a state of high-frequency vibration as it moves downward. When the pressure plate 64 moves downward into the bottom mold 2, it will generate high-frequency vibration on the side wall of the inner cavity of the bottom mold 2, causing the bubbles attached to the side wall of the inner cavity of the bottom mold 2 to quickly detach and float upward and break.
[0062] The present invention provides another embodiment:
[0063] A one-piece molding process for foamed shoe soles includes the following steps:
[0064] Step 1: Pour the foaming material evenly onto the bottom mold 2, then start the equipment to make the top mold 5 slide down inside the main body 1 and close with the bottom mold 2. During the downward movement of the top mold 5, the lead screw 62 abuts against the upper surface of the bottom mold 2. When the lead screw 62 slides into the top mold 5, the camshaft 67 will rotate and drive the striking block 68 to strike the side wall of the pressure plate 64. At the same time, the pressure plate 64 will move down and adhere to the surface of the foaming material. The high-frequency vibrating pressure plate 64 slides into the bottom mold 2 and causes the inner cavity side wall of the bottom mold 2 to resonate with it.
[0065] Step two: after the foaming material is poured into the bottom mold 2, the motor 32 is started and rotates the cover plate 31 through the magnetic coupling of the magnetic plate 33 and the cover plate 31, the first sliding rod 3101 in the cover plate 31 slides out of the cover plate 31 under the action of centrifugal force, and the brush strip 3103 on the first sliding rod 3101 sweeps the bottom of the inner cavity of the bottom mold 2, so that the foaming material is evenly spread on the bottom mold 2;
[0066] Step three: during the rotation of the motor 32, the rotating assembly 3 in the limiting frame 34 slides under the combined limiting action of the limiting frame 34 and the guide ring 38, and the third sliding rod 36 is pressed against the bottom of the inner cavity of the bottom mold 2, so that the first spring 37 is first contracted and then rebounded, the third sliding rod 36 knocks the bottom of the bottom mold 2, and the bubbles attached to the bottom of the inner cavity of the bottom mold 2 are separated from the bottom of the bottom mold 2 during the knocking process of the third sliding rod 36;
[0067] Step four: when the foaming material is formed between the bottom mold 2 and the top mold 5, the top mold 5 is lifted in the equipment main body 1, the top mold 5 is lifted during the lifting process, the gear plate 43 is engaged with the gear rack 42 and is vertically turned to the horizontal state, the second tooth shaft 411 is engaged with the gear groove 412 when the carrier plate 41 is lifted, the first tooth shaft 49 is engaged with the bevel gear shaft 48 and drives the sliding frame 481 and the sole to rotate, the hot melting head 46 is attached to the side of the sole during the rotation of the sole, and the burr on the side of the sole during the forming process is cleaned, so that the edge of the formed sole is smooth, and the staff does not need to process the burr again.
