Description

Technical Field

[0001] This invention belongs to the field of shoe sole production technology, and in particular relates to a one-time molding equipment and process for foamed shoe soles. Background Technology

[0002] Foam soles are widely used in athletic shoes, casual shoes, and other products due to their lightweight, wear-resistant, and excellent elasticity. Their molding quality directly determines the comfort and lifespan of the footwear. Currently, the mainstream foam sole molding process in the industry mostly adopts compression molding technology, which involves injecting foam material into a mold cavity, heating it to foam, and then cooling and solidifying it to complete the molding process.

[0003] During the filling and foaming process of foamed materials in the mold, uneven material flow and air adhering to the inner wall of the mold can easily lead to air bubbles remaining on the side walls, bottom, or inside the material of the mold cavity. Traditional equipment lacks a targeted defoaming mechanism, relying solely on the material's own flowability or simple venting holes in the mold, which is insufficient to completely eliminate microbubbles adhering to the inner wall of the mold. These residual air bubbles can cause defects such as material shortages, dents, and pinholes on the surface of the molded shoe sole, affecting not only the product's appearance but also reducing the structural strength of the sole, making it prone to cracking during use and significantly increasing production costs.

[0004] When foamed material is foamed in the mold cavity, some material overflows the mold closing gap, forming flash. Current processes require secondary processing, either manually or with a separate flash trimming device, after the sole is formed and demolded. Manual trimming suffers from low precision, poor consistency, high labor intensity, and is prone to damaging the edge structure of the sole. Summary of the Invention

[0005] The purpose of this invention is to provide a one-time molding equipment and process for foamed shoe soles, aiming to solve the technical problems existing in the prior art mentioned in the background.

[0006] The present invention is implemented as follows: a foam shoe sole one-time molding device includes a device body, a bottom mold, and a top mold. The bottom mold is fixedly connected to the bottom of the inner cavity of the device body, and the top mold is slidably connected to the inside of the device body and located above the bottom mold. The device also includes: A rotating assembly is disposed inside the main body of the equipment. The rotating assembly is used to evenly distribute the foaming material inside the bottom mold. The rotating assembly includes a cover plate rotatably connected to the top of the bottom mold. A motor is installed inside the bottom mold and below the cover plate. A magnetic plate magnetically coupled to the cover plate is fixedly connected to the top of the motor. Limit frames are evenly fixedly connected to the outer wall of the motor. Sliders are slidably connected inside the limit frames. A third slide rod is slidably connected inside the sliders. A first spring is fixedly connected between the third slide rod and the slider. A guide ring is fixedly connected to the bottom of the bottom mold cavity. The bottom of the third slide rod is slidably engaged inside the guide ring. The edge trimming assembly, located inside the main body of the equipment, is used to trim the edges of the molded shoe sole. The defoaming component is located inside the top mold and is used to defoam the foaming material after it has been filled into the bottom mold.

[0007] As a preferred technical solution of the present invention: the cover plate is symmetrically slidably connected to a first slide rod, a second spring is fixedly connected between the first slide rod and the inner wall of the cover plate, and brush strips are fixedly connected to the outer wall of the first slide rod in a ring array.

[0008] As another preferred technical solution of the present invention: a carrier plate is slidably connected to the bottom of the top mold, a rack is fixedly connected inside the main body of the equipment, the carrier plate and the rack are slidably engaged, a toothed plate is symmetrically rotatably connected to the middle of the carrier plate, a sliding plate is slidably connected inside the toothed plate, a third spring is installed between the side wall of the sliding plate and the outer wall of the carrier plate, a hot melt head is installed on the end side of the sliding plate, a roller is symmetrically rotatably connected to the side wall of the hot melt head, a bevel gear shaft is rotatably connected to the carrier plate, a first toothed shaft meshing with the bevel gear shaft is rotatably connected to the upper surface of the carrier plate, a second toothed shaft is rotatably connected to the side of the carrier plate near the inner wall of the main body of the equipment, a fourth spring is fixedly connected between the second toothed shaft and the first toothed shaft, and a toothed groove meshing with the second toothed shaft is opened on the side wall of the main body of the equipment.

[0009] As another preferred technical solution of the present invention: a slide is fixedly connected to the top of the bevel gear shaft, the slide is slidably fitted inside the bottom mold, side plates are symmetrically slidably connected to the side walls of the slide, a sixth spring is fixedly connected between the side plates and the slide, a top plate is rotatably connected to the top of the side plates, a seventh spring is fixedly connected between the top plate and the side plates, a first positioning rod is fixedly connected to the side wall of the top plate, and a positioning groove that slidably fits with the first positioning rod is opened inside the slide.

[0010] As another preferred technical solution of the present invention: the bottom of the side plate is inclined, the side wall of the side plate is in contact with the inner wall of the bottom mold inside the bottom mold, and the bottom of the top plate is serrated.

[0011] As another preferred technical solution of the present invention: the defoaming component includes symmetrically formed U-shaped air grooves inside the top mold, one end of the U-shaped air groove is slidably connected to a lead screw, a fifth spring is fixedly connected between the lead screw and the top mold, the other end of the U-shaped air groove is slidably connected to a second slide rod, the bottom of the second slide rod is fixedly connected to a pressure plate, the middle of the pressure plate is connected to an injection pipe, a camshaft is rotatably connected inside the top mold, the camshaft and the lead screw are slidably engaged, a striking block is rotatably connected inside the top mold, a second positioning rod is fixedly connected to the side of the striking block near the camshaft and slidably engaged with the camshaft, and the end of the striking block abuts against the side wall of the pressure plate.

[0012] A one-piece molding process for foamed shoe soles includes the following steps: Step 1: Pour the foaming material evenly onto the bottom mold, then start the equipment to make the top mold slide down inside the main body of the equipment to close with the bottom mold. During the downward movement of the top mold, the lead screw abuts against the upper surface of the bottom mold. When the lead screw slides into the top mold, the camshaft will rotate and drive the striking block to strike the side wall of the pressure plate. At the same time, the pressure plate will move down and adhere to the surface of the foaming material. The high-frequency vibrating pressure plate slides into the bottom mold and causes the inner cavity side wall of the bottom mold to resonate with it. Step 2: After the foaming material is poured into the bottom mold, the motor starts and drives the cover plate to rotate through the magnetic coupling between the magnetic plate and the cover plate. The first slide rod inside the cover plate slides out of the cover plate under the action of centrifugal force. The brush strip on the first slide rod will scrape the bottom of the bottom mold cavity, so that the foaming material is evenly spread on the bottom mold. Step 3: During the rotation of the motor, the rotating component inside the limiting frame will slide under the combined limiting effect of the limiting frame and the guide ring. When the third slide rod is squeezed by the bottom of the bottom mold cavity, the first spring will first contract and then rebound, causing the third slide rod to strike the bottom of the bottom mold. The air bubbles attached to the bottom of the bottom mold cavity will detach from the bottom of the bottom mold during the striking process of the third slide rod. Step 4: After the foaming material is formed between the bottom mold and the top mold, the top mold is lifted inside the main body of the equipment. During the upward movement of the top mold, the carrier plate will also move upward. After the toothed plate and the toothed rack mesh, it will flip from vertical to horizontal. When the carrier plate moves upward, the second toothed shaft will mesh with the toothed groove, so that the slide can slide out of the bottom mold. Then, the first toothed shaft will mesh with the bevel toothed shaft and drive the slide and the sole to rotate. When the sole rotates, the hot melt head will fit against the side of the sole and clean the rough edges on the side during the sole forming process, so that the edge of the sole is smooth after forming, and no secondary processing of the rough edges is required by the staff.

[0013] The beneficial effects of the embodiments of the present invention are as follows: 1. The third slide bar evenly taps the bottom of the bottom mold, causing the air bubbles in the foam material that are attached to the inner wall of the bottom mold to detach from the inner wall of the bottom mold and float upward under the action of the tapping and vibration of the third slide bar. This avoids the problem of gaps on the surface of the molded shoe sole due to insufficient foaming caused by air bubbles attached to the inner wall of the bottom mold during the foaming process. 2. After the first sliding rod slides out of the cover plate, the brush strip is no longer limited by the inner cavity of the cover plate and spreads out in an umbrella shape. During the rotation of the first sliding rod and the brush strip with the cover plate, the brush strip will scrape the surface of the bottom mold, thereby ensuring that there are no air bubbles adhering to the inner wall of the bottom mold in the foaming material, thus improving the quality of the product after foaming and molding. 3. After the conical gear shaft moves upward, it will cause the formed shoe sole to rise and be demolded from inside the bottom mold. When the conical gear shaft is completely detached from the bottom mold, it will cause the shoe sole to rotate above the bottom mold. At this time, the hot melt head will trim the edge of the formed shoe sole, so that the formed shoe sole does not need to be removed by the staff for trimming, simplifying the staff's operation process.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0018] like Figures 1 to 7 As shown, in one embodiment, a foam shoe sole one-time molding device is proposed, including a device body 1, a bottom mold 2, and a top mold 5. The bottom mold 2 is fixedly connected to the bottom of the inner cavity of the device body 1, and the top mold 5 is slidably connected to the inside of the device body 1 and located above the bottom mold 2. The device also includes: Rotating component 3 is disposed inside the main body 1 of the equipment. Rotating component 3 is used to evenly distribute foaming material inside the bottom mold 2. Rotating component 3 includes a cover plate 31 rotatably connected to the top of the bottom mold 2. A motor 32 is installed inside the bottom mold 2 and below the cover plate 31. A magnetic plate 33 magnetically coupled to the cover plate 31 is fixedly connected to the top of the motor 32. Limiting frame 34 is evenly fixedly connected to the outer wall of the motor 32. A slider 35 is slidably connected inside the limiting frame 34. A third sliding rod 36 is slidably connected inside the slider 35. A first spring 37 is fixedly connected between the third sliding rod 36 and the slider 35. A guide ring 38 is fixedly connected to the bottom of the inner cavity of the bottom mold 2. The bottom of the third sliding rod 36 is slidably engaged inside the guide ring 38. The edge trimming component 4 is located inside the main body 1 of the equipment and is used to trim the edges of the molded shoe sole. The defoaming component 6 is located inside the top mold 5 and is used to defoam the foaming material after filling the bottom mold 2.

[0019] In practical application, the operator uses the equipment to pour the foaming liquid into the bottom mold 2, and then starts the motor 32. When the motor 32 rotates, it drives the cover plate 31 to rotate through the magnetic coupling of the magnetic plate 33 and the cover plate 31. During the rotation, the cover plate 31 causes the foaming material inside the bottom mold 2 to flow to the edge, thereby spreading the foaming material evenly inside the bottom mold 2 and ensuring that the foaming material can completely fill the inside of the bottom mold 2 when it foams.

[0020] As the motor 32 drives the limiting frame 34 to rotate, the third slide rod 36, limited by the guide ring 38, will drive the slider 35 to slide back and forth inside the limiting frame 34. As the third slide rod 36 revolves around the motor 32, the top of the third slide rod 36 will be continuously compressed, causing the first spring 37 to elastically contract. When the rotating component 3 is no longer compressed, the first spring 37 will rebound, causing the third slide rod 36 to strike the bottom of the bottom mold 2. Through the limiting of the third slide rod 36 by the guide ring 38, the third slide rod 36 can strike the bottom of the bottom mold 2 evenly, causing the air bubbles in the foam material attached to the inner wall of the bottom mold 2 to detach from the inner wall of the bottom mold 2 and float upward under the action of the striking vibration of the third slide rod 36. This avoids the problem of gaps on the surface of the molded shoe sole due to insufficient foaming caused by air bubbles attached to the inner wall of the bottom mold 2 during the foaming process.

[0021] like Figure 7 As 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.

[0022] 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.

[0023] 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.

[0024] 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. When the carrier plate 41 moves upward, it will drive the second toothed shaft 411 to move upward together. When the second toothed shaft 411 moves upward, it will mesh with the toothed groove 412 and rotate. During the rotation of the second toothed shaft 411, since the beveled shaft 48 is still inside the bottom mold 2, the first toothed shaft 49 meshing with the beveled shaft 48 cannot rotate. Therefore, the fourth spring 410 will twist and generate torque after the second toothed shaft 411 rotates. When the beveled shaft 48 completely slides out of the bottom mold 2, the torque of the fourth spring 410 is released, and the beveled shaft 48 is driven to rotate through the first toothed shaft 49. After the conical shaft 48 moves upward, it will cause the formed shoe sole to rise and be demolded from the bottom mold 2. When the conical shaft 48 is completely detached from the bottom mold 2, it will cause the shoe sole to rotate above the bottom mold 2. At this time, the hot melt head 46 will trim the edge of the formed shoe sole, so that the formed shoe sole does not need to be removed by the staff for trimming, simplifying the staff's operation process.

[0025] like Figure 11 As shown, in another preferred embodiment of the present invention, a slide 481 is fixedly connected to the top of the bevel gear shaft 48. The slide 481 is slidably fitted inside the bottom mold 2. Side plates 482 are symmetrically slidably connected to the side walls of the slide 481. A sixth spring 483 is fixedly connected between the side plates 482 and the slide 481. A top plate 484 is rotatably connected to the top of the side plates 482. A seventh spring 485 is fixedly connected between the top plate 484 and the side plates 482. A first positioning rod 486 is fixedly connected to the side wall of the top plate 484. A positioning groove 487 that slidably fits with the first positioning rod 486 is provided inside the slide 481.

[0026] In practical application, when the bevel gear shaft 48 moves upward and drives the slide 481 out of the bottom mold 2, the sixth spring 483 elastically extends and pushes the side plate 482 to slide away from the slide 481. When the side plate 482 slides, it drives the top plate 484 to slide laterally together. The first positioning rod 486 on the side wall of the top plate 484 slides in the positioning groove 487, causing the top plate 484 to flip on top of the side plate 482. This causes the top plate 484 to lift outward during the lateral movement with the side plate 482, allowing the top plate 484 to be inserted into the bottom of the formed shoe sole. After the top plates 484 on both sides are inserted into the shoe sole, the shoe sole is fixed and keeps stable on the bevel gear shaft 48 and rotates with the bevel gear shaft 48.

[0027] like Figure 11 As shown, in another preferred embodiment of the present invention, the bottom of the side plate 482 is inclined, the side wall of the side plate 482 is attached to the inner wall of the bottom mold 2 inside the bottom mold 2, and the bottom of the top plate 484 is serrated.

[0028] like 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.

[0029] 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.

[0030] 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.

[0031] The present invention provides another embodiment: A one-piece molding process for foamed shoe soles includes the following steps: 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. Step 2: After the foaming material is poured into the bottom mold 2, the motor 32 starts and drives the cover plate 31 to rotate through the magnetic coupling of the magnetic plate 33 and the cover plate 31. The first slide rod 3101 inside the cover plate 31 slides out of the cover plate 31 under the action of centrifugal force. The brush strip 3103 on the first slide rod 3101 will scrape the bottom of the inner cavity of the bottom mold 2, so that the foaming material is evenly spread on the bottom mold 2. Step 3: During the rotation of motor 32, the rotating component 3 inside the limiting frame 34 will slide under the combined limiting effect of the limiting frame 34 and the guide ring 38. When the third slide rod 36 is squeezed by the bottom of the inner cavity of the bottom mold 2, the first spring 37 will first contract and then rebound, causing the third slide rod 36 to strike the bottom of the bottom mold 2. The air bubbles attached to the bottom of the inner cavity of the bottom mold 2 will detach from the bottom of the bottom mold 2 during the striking process of the third slide rod 36. Step 4: After the foaming material is formed between the bottom mold 2 and the top mold 5, the top mold 5 is lifted inside the main body 1 of the equipment. During the upward movement of the top mold 5, the carrier plate 41 will also be moved upward. After the toothed plate 43 engages with the toothed rack 42, it will flip from vertical to horizontal. When the carrier plate 41 moves upward, the second toothed shaft 411 will engage with the toothed groove 412, so that the slide 481 slides out of the bottom mold 2. Then, the first toothed shaft 49 will engage with the beveled shaft 48 and drive the slide 481 and the sole to rotate. When the sole rotates, the hot melt head 46 will fit against the side of the sole and clean the rough edges on the side during the sole forming process, so that the edge of the sole is smooth after forming, and no secondary processing of the rough edges is required by the staff.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

7. A process for one-shot molding of a foamed shoe sole, applied to the one-shot molding apparatus for a foamed shoe sole according to any one of claims 1 to 6, characterized by, Includes the following steps: 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. Step 2: After the foaming material is poured into the bottom mold (2), the motor (32) starts and drives the cover plate (31) to rotate through the magnetic coupling of the magnetic plate (33) and the cover plate (31). The first slide rod (3101) inside the cover plate (31) slides out of the cover plate (31) under the action of centrifugal force. The brush strip (3103) on the first slide rod (3101) will scrape the bottom of the inner cavity of the bottom mold (2) so that the foaming material is evenly spread on the bottom mold (2). Step 3: During the rotation of the motor (32), the rotating component (3) inside the limiting frame (34) will slide under the combined limiting effect of the limiting frame (34) and the guide ring (38). When the third slide rod (36) is squeezed by the bottom of the inner cavity of the bottom mold (2), the first spring (37) will first contract and then rebound, so that the third slide rod (36) will strike the bottom of the bottom mold (2). The air bubbles attached to the bottom of the inner cavity of the bottom mold (2) will detach from the bottom of the bottom mold (2) during the striking process of the third slide rod (36). Step 4: After the foaming material is formed between the bottom mold (2) and the top mold (5), the top mold (5) is lifted inside the main body (1) of the equipment. During the upward movement of the top mold (5), the carrier plate (41) will be moved upward together. After the toothed plate (43) meshes with the toothed rack (42), it flips from vertical to horizontal. When the carrier plate (41) moves upward, the second toothed shaft (411) will mesh with the toothed groove (412), so that the slide (481) slides out of the bottom mold (2). Then the first toothed shaft (49) will mesh with the beveled shaft (48) and drive the slide (481) and the sole to rotate. When the sole rotates, the hot melt head (46) will fit with the side of the sole and clean the rough edges on the side during the sole forming process, so that the edge of the sole is smooth after forming, and no secondary processing of the rough edges is required by the staff.
