Description

Technical Field

[0001] The present application relates to the technical field of material forming, and in particular to a slipper mold. Background Art

[0002] Polymer foam slippers, thanks to their unique materials and manufacturing process, are lightweight, wear-resistant, anti-aging, and offer excellent cushioning properties. They are comfortable to wear, making them a popular choice for consumers at home and outdoors. They are manufactured through a process that combines the main material (EVA or PE) with auxiliary materials (such as a foaming agent and lubricant) through a mixing process, followed by a foaming process. The foaming process involves injecting the mixed materials into a mold, heating the mold to reach the foaming temperature, and finally cooling it to set the slippers. While molds play a crucial role in manufacturing, existing molds still present the following challenges: 1. The existing mold uses a rigid demolding mechanism to eject multiple slippers at one time. The slippers have just been hot-pressed and the adhesion between each slipper and the mold cavity is different. Some slippers are easily stuck to the mold cavity. If the slippers are ejected at the same time, they are easily damaged. Forced separation will cause wire drawing, scratches or local damage on the surface of the injection molded parts. In addition, the movable mold is prone to offset during the long-term opening and closing process during long-term use. The offset of the movable mold will change the shape and size of the mold cavity, resulting in the size of the produced slippers not meeting the design requirements. The offset may cause the mold to be loose, resulting in defects such as flash and burrs on the product surface, reducing the surface finish of the product and affecting the aesthetics of the product. The offset of the movable mold will cause the mold to bear uneven force during the clamping process. If it is not discovered in time, it will aggravate the wear of the mold and shorten the service life of the mold.

[0003] 2. When filling raw materials in existing molds, the EVA foam material is divided into equal amounts by weighing, and then the EVA foam material is placed in the mold cavity for hot pressing according to the required weight, resulting in low production efficiency. If quantitative filling is not performed, it is easy to cause inconsistent expansion of the material during the foaming process, resulting in defects such as unevenness and wrinkles on the surface of the slippers, affecting the aesthetics of the product. Summary of the Invention

[0004] In order to overcome the rigid demoulding mechanism, multiple slippers are ejected at one time. However, the slippers have just been hot-pressed and the adhesion between each slipper and the mold cavity is different. Some slippers are easily stuck to the mold cavity. If the slippers are ejected at the same time, it is easy to damage the slippers. When forced to separate, it will cause wire drawing, scratches or local damage on the surface of the injection molded parts. In addition, the movable mold is prone to offset during the long-term opening and closing process during long-term use. The offset of the movable mold will change the shape and size of the mold cavity, resulting in the size of the produced slippers not meeting the design requirements. The offset may cause the mold to be loose and cause defects on the product surface. Defects such as flash and burrs are generated, which reduce the surface finish of the product and affect the aesthetics of the product.

If the slippers are ejected at the same time, they are easily damaged. When forced to separate, wire drawing, scratches or local damage may appear on the surface of the injection molded parts. In addition, the movable mold is prone to offset during the long-term opening and closing process during long-term use.

The present invention can flexibly eject the hot-pressed slippers through the demoulding component, and the ejection force of multiple slippers can be different according to the different sticking force, thereby preventing damage to the slippers during demoulding. In addition, after long-term use, it can detect whether the movable mold is offset and tilted, ensuring that the mold can be tightly closed during the hot pressing process. When the movable mold deviates, an alarm can be issued in time to remind the staff to perform timely maintenance, thereby increasing the service life of the equipment.

[0016] 2. The use of the feeding component effectively solves the problem that the existing molds divide the EVA foam material into equal amounts by weighing when filling the raw materials, and then place the EVA foam material in the mold cavity for hot pressing according to the required weight, which leads to low production efficiency. If quantitative filling is not performed, it is easy to cause inconsistent material expansion during the foaming process, resulting in defects such as unevenness and wrinkles on the surface of the slippers, affecting the aesthetics of the product. The present invention can add EVA foam material in a quantitative manner through the feeding component, and can adjust the quantitative capacity according to the different sizes of the slippers, so that the surface of the produced slippers is more complete, and there is no waste of raw materials. During the blanking process, the raw materials can fall down completely, thereby improving the accuracy of raw material addition. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Ejecting the slippers at the same time can easily damage the slippers. The present invention can eject the hot-pressed slippers with flexible force through the demoulding component, and multiple slippers can be ejected with different forces according to the different adhesion forces, thereby preventing the slippers from being damaged during demoulding. When filling the mold with raw materials, the EVA foam material is divided into equal amounts by weighing. The present invention can add EVA foam material in a quantitative manner through the feeding component, and the quantitative capacity can be adjusted according to the different sizes of the slippers.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example: See also Figure 1 and Figure 2As shown, a slipper mold comprises a foaming frame 1, a bottom mold 3 and a top mold 5. The inner cavity of the bottom end of the foaming frame 1 is slidably connected to a telescopic platform 2. The bottom mold 3 is fixedly installed on the upper surface of the telescopic platform 2. Guide rods 4 are provided at the four corners of the upper surface of the bottom mold 3. The top bottom wall of the foaming frame 1 is fixedly installed with a top mold 5. The lower surface of the top mold 5 is provided with a shoe model 6. The inner cavity of the bottom mold 3 is provided with a demoulding component 7. The outer surface of the foaming frame 1 is slidably connected with a feeding component 8. The bottom end of the foaming frame 1 is provided with a cylinder. The piston rod of the cylinder is fixedly connected to the telescopic platform 2. Limiting grooves are provided at the four corners of the top mold 5. The guide rods 4 are inserted into the limiting grooves. A mold cavity is provided on the upper surface of the bottom mold 3. The mold cavity and the shoe model 6 are aligned. The top mold 5 The inner cavity is provided with an electric heating pipe, and the feeding component 8 is moved to the position of the outer surface of the foaming frame 1. The EVA foam material is discharged in equal amounts on the mold cavity on the upper surface of the bottom mold 3 through the feeding component 8. After the discharge is completed, the feeding component 8 is moved to the side of the bottom mold 3, and the telescopic table 2 is driven upward by the cylinder at the bottom end of the foaming frame 1 to align the bottom mold 3 and the top mold 5. The guide rod 4 is inserted into the limiting groove on the lower surface of the top mold 5. At this time, according to the size of the shoe model 6 and by heating the electric heating pipe in the inner cavity of the top mold 5, the EVA foam material is hot-pressed. When the cylinder contracts, the demoulding component 7 can flexibly demould the slippers in the mold cavity of the bottom mold 3, and the flexibility of each slipper is different to prevent scratches on the outer surface of the hot-pressed slippers.

[0022] See also Figure 3 and Figure 4 As shown, the demoulding assembly 7 includes a slide plate 71, the upper surface of the slide plate 71 is provided with a demoulding mechanism 72, the lower surface of the slide plate 71 is provided with a lifting mechanism 73, and the lower surface of the bottom mold 3 is provided with a positioning detection mechanism 74. When the bottom mold 3 descends, the lifting mechanism 73 drives the slide plate 71 to slide in the inner cavity of the bottom mold 3, so that the demoulding mechanism 72 performs a flexible demoulding process on the slippers in the mold cavity of the bottom mold 3. The positioning detection mechanism 74 is used to detect whether the bottom mold 3 is offset under long-term use, so as to facilitate timely subsequent maintenance.

[0023] See also Figure 4 、 Figure 5 and Figure 6As shown, the demoulding mechanism 72 includes a pressure frame 721, and pressure cylinders 722 are rotatably connected to the two ends of the pressure frame 721. A flexible frame 723 is provided above the pressure frame 721, and demoulding rods 724 are fixedly installed at both ends of the flexible frame 723. The inner cavities at both ends of the flexible frame 723 are slidably connected to first slide bars 725, and the outer surface of the first slide bar 725 is sleeved with a first spring 726. One end of the first slide bar 725 is fixedly installed with a pressure block 727, one end of the flexible frame 723 is provided with a first button 728, and the outer surface of the flexible frame 723 is fixedly installed with a first alarm 729. The bottom end of the pressure frame 721 is fixedly connected to the slide plate 71, and the demoulding rod 724 is slidably connected to the bottom mold 3, and the top of the demoulding rod 724 is connected to the bottom mold 3 The mold cavity on the upper surface is formed as a whole, the first spring 726 is located between the inner wall of the flexible frame 723 and the pressure block 727, the first button 728 is aligned with a first slide bar 725 at the upper end, the first button 728 is electrically connected to the first alarm 729, and pressing the first button 728 controls the first alarm 729 to sound an alarm, the outer surface of the pressure block 727 is an inclined surface, and the inclined surfaces of the pressure cylinder 722 and the pressure block 727 are aligned, so as to squeeze the first spring 726 when the pressure cylinder 722 moves upward, and there is a gap between the inclined surfaces of the pressure cylinder 722 and the pressure block 727 when the slide 71 is located in the inner cavity at the bottom end of the bottom mold 3, and the lifting mechanism 73 includes a limit block 731, and the inner cavity of the limit block 731 is rotatably connected to the gear 73 2. A first rack 733 is provided on one side of the limit block 731. The first rack 733 meshes with the gear 732. The inner cavity of the limit block 731 is slidably connected with the second rack 734. The second rack 734 meshes with the gear 732. The limit block 731 is fixedly connected to the outer surface of the foaming frame 1. The first rack 733 is fixedly connected to the inner wall of the bottom mold 3. When demoulding, the bottom mold 3 and the top mold 5 are separated. At this time, the cylinder drives the telescopic table 2 to be retracted into the bottom end cavity of the foaming frame 1. The downward movement of the bottom mold 3 drives the slide plate 71 to move downward. The downward movement of the bottom mold 3 also drives the first rack 733 to move downward. The downward movement of the first rack 733 drives the gear 732 to rotate. The rotation of the gear 732 drives the second rack 734 to move upward. The upward movement of the second rack 734 The slide plate 71 is squeezed, and the slide plate 71 slides upward in the inner cavity of the bottom mold 3. The upward sliding of the lifting mechanism 73 drives the pressure frame 721 to move upward, and the upward movement of the pressure frame 721 drives the pressure cylinder 722 to squeeze the pressure block 727. In the process of the pressure cylinder 722 squeezing the pressure block 727, the pressure block 727 squeezes the first spring 726, causing the first slide bar 725 to slide in the inner cavity of the flexible frame 723. In this way, the formed slippers and the mold cavity of the bottom mold 3 will not be directly squeezed when they are pasted together. That is, at this time, the pressure cylinder 722 generates an upward squeezing force to drive the first slide bar 725 to slide in the inner cavity of the flexible frame 723, and the flexible frame 723 does not move up and down, so that the demoulding rod 724 does not move directly upward.When the slide plate 71 moves upward, the demoulding rod 724 cannot move upward, and the upward movement of the pressure frame 721 squeezes the pressure block 727 at the upper end. The first slide bar 725 is moved to press the first button 728. The pressing of the first button 728 drives the first alarm 729 to sound an alarm, which increases the staff's awareness of the difficulty in demolding the slippers in the mold cavity and requires maintenance. During maintenance, the pressure cylinder 722 and the pressure block 727 need to be restored to their original positions. Lubricant can be added to the mold cavity to improve the demolding effect. When the bottom mold 3 moves up a short distance, the demolding rod 724 and the mold cavity at the upper end of the bottom mold 3 form a whole. At this time, material can be added to prevent the EVA foam material from falling into the cavity formed by the demolding rod 724 and the mold cavity. At this time, the first rack 733 moves up to drive the gear 732 to rotate. The rotation of the gear 732 drives the second rack 734 to slide down. That is, the slide plate 71 returns to the bottom end of the inner cavity of the bottom mold 3 under the action of gravity. The pressure cylinder 722 will no longer generate squeezing force on the pressure block 727, ensuring that the demolding rod 724 and the mold cavity of the bottom mold 3 form a whole during hot pressing, ensuring that the outer surface of the slippers is intact.

The first threaded rod 7410 is movably connected to the inner cavity of the positioning frame 746, and the slider 7411 is slidably connected to the inner cavity of the positioning frame 746. The outer surface of the slider 7411 is fixedly installed with a second alarm 7412. Second buttons 7413 are provided at both ends of the floating block 747. A positioning groove 7414 is provided in the middle part of the floating block 747. The second spring 749 is located between the floating block 747 and the inner wall of the positioning frame 746. The second alarm 7412 and the second button 7413 are electrically connected. Pressing the second button 7413 controls the second alarm 7412 to sound an alarm. The two ends of the positioning groove 7414 are inclined toward the positioning groove 7414. The first threaded rod 7410 and the slider 7411 are connected by threads, and the threads at the two ends of the first threaded rod 7410 are in opposite directions. There is a gap between the button 7413 and the slider 7411, the connecting strip 742 and the positioning frame 746 are parallel, and when the cylinder in the inner cavity of the foaming frame 1 contracts, the outer surface of the detection block 743 and the positioning frame 746 fit closely, and at this time the positioning wheel 744 and the positioning groove 7414 fit closely, and the horizontal detection mechanism 745 includes a detection frame 7451, the bottom end inner cavity of the detection frame 7451 is on the outer surface of the foaming frame 1, the inner cavity of the detection frame 7451 is slidably connected to the slide 7452, the bottom end of the slide 7452 is sleeved with a third spring 7453, the third spring 7453 is located between the slide 7452 and the bottom wall of the detection frame 7451, the top inner cavity of the slide 7452 is rotatably connected to the pressure wheel 7454, and the top inner cavity of the detection frame 7451 is rotatably connected to the balance block 7455 The balancing block 7455 is symmetrically distributed about the pressure wheel 7454, and the bottom end of the balancing block 7455 is tightly fitted with the pressure wheel 7454. A pointer 7456 is fixedly installed on the outer surface of the balancing block 7455, and a positioning frame 746 is fixedly installed on the upper surface of the balancing block 7455. The positioning frame 746 and the pointer 7456 are perpendicular, and the pointer 7456 is vertically downward. The tilt of the bottom mold 3 can be detected according to the inclination of the pointer 7456. It is easy to offset during the up and down movement of the bottom mold 3. The position of the bottom mold 3 is detected by the positioning detection mechanism 74. The downward movement of the bottom mold 3 drives the connecting rod 741 to move downward. The downward movement of the connecting rod 741 drives the connecting bar 742 to move downward. The downward movement of the connecting bar 742 drives the detection block 743 and the positioning wheel 744 to move downward.When the cam 7411 is in the closed position, the second stop 7413 is pressed against the stop 7414, and the second stop 7413 is pressed against the stop 7415. When the cam 7411 is in the closed position, the second stop 7413 is pressed against the stop 7416, and the second stop 7417 is pressed against the stop 7417. The resulting extrusion causes the positioning frame 746 to drive the balancing block 7455 to rotate in the inner cavity of the detection frame 7451. The rotation of the balancing block 7455 drives the balancing block 7455 to squeeze the pressure wheel 7454. At this time, the slide 7452 slides in the inner cavity of the detection frame 7451 and the third spring 7453 is compressed. When the bottom mold 3 moves up, the elastic force of the third spring 7453 keeps the positioning frame 746 horizontal, which is convenient for repeated detection. At the same time, the rotation of the balancing block 7455 drives the pointer 7456 to rotate, so that the pointer 7456 The direction of the pointer 7456 changes, making it easy to judge the tilt of the bottom mold 3 according to the direction of the pointer 7456, so as to promptly detect the tilt of the bottom mold 3 and perform maintenance on the bottom mold 3. When the positioning frame 746 tilts, the positioning wheel 744 can also squeeze the positioning groove 7414, thereby realizing simultaneous detection of the tilt and deviation, ensuring that the deviation of the bottom mold 3 is promptly detected and maintained, so that the mold is tightly closed, and defects such as flash and burrs are avoided on the surface of the hot-pressed product, thereby improving the surface finish and aesthetics of the product.

[0025] See also Figure 1 and Figure 10As shown, the feeding assembly 8 includes a feeding rack 81, a hopper 82 is fixedly installed in the middle part of the feeding rack 81, a feeding port 83 is provided on the outer surface of the feeding rack 81, and there are two feeding ports 83. A feeding box 84 is slidably connected to the upper surface of the feeding rack 81, and grooves 85 are provided at both ends of the feeding box 84. A knocking mechanism 86 is fixedly installed at both ends of the feeding rack 81, and an adjusting mechanism 87 is provided in the inner cavity of the feeding box 84. The feeding rack 81 is slidably connected to the outer surface of the foaming rack 1. When the feeding rack 81 slides on the outer surface of the foaming rack 1, the feeding port 83 is aligned with the mold cavity of the bottom mold 3. A connecting hole 88 is provided in the middle part of the feeding box 84 for receiving the raw material of the hopper 82. The EVA foaming material is placed on the upper end of the hopper 82 so that the EVA foaming material enters the inner cavity of the feeding box 84. At this time, the feeding box 84 is moved so that the feeding box 84 Move to the upper end of the discharge port 83. At this time, the EVA foam material in the discharge box 84 falls from the discharge port 83 into the cavity of the bottom mold 3 for subsequent hot pressing. By moving the discharge rack 81 on the outer surface of the foaming rack 1, the discharge box 84 is moved on the two discharge ports 83 on the discharge rack 81. Since the capacity of the discharge box 84 is fixed, equal loading of the upper cavity of the bottom mold 3 is achieved. During the loading process, the knocking mechanism 86 can knock on the discharge box 84 to prevent the EVA foam material from adhering to the inner wall of the discharge box 84, thereby ensuring the accuracy of equal loading of the EVA foam material. The adjustment mechanism 87 is used to adjust the capacity of the inner cavity of the discharge box 84, which is convenient for adjustment according to the size of the hot-pressed slippers, so that the EVA foam material discharged can be quantitatively adjusted according to different hot-pressed slippers, thereby improving production efficiency.

[0026] See also Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the knocking mechanism 86 includes a knocking frame 861, the knocking frame 861 is fixedly connected to the blanking frame 81, and the middle part of the top of the knocking frame 861 is slidably connected with an elastic rod 862, and a fixing ring 863 is fixedly installed on the outer surface of the elastic rod 862. The outer surface of the elastic rod 862 is sleeved with a fourth spring 864, and the fourth spring 864 is located between the bottom wall of the knocking frame 861 and the fixing ring 863. The bottom end of the elastic rod 862 fits in the inner cavity of the groove 85, and the bottom end of the elastic rod 862 is rounded, so that the elastic rod 862 can move up and fit in the groove when it contacts the upper surface of the blanking box 84. When the groove 85 contacts, the fourth spring 864 generates an elastic force on the fixing ring 863, causing the elastic rod 862 to move back and forth in the inner cavity of the knocking frame 861, thereby forming a knocking effect on the blanking box 84, and the adjusting mechanism 87 includes a second threaded rod 871, the second threaded rod 871 and the blanking box 84 are rotatably connected, and the two ends of the second threaded rod 871 are rotatably connected to the adjusting block 872 through a thread, and the thread directions of the two ends of the second threaded rod 871 are opposite, and the inner cavity of the blanking box 84 is slidably connected with a shielding plate 873, the shielding plate 873 and the adjusting block 872 are fixedly connected, and the inner cavities at both ends of the blanking box 84 slide The capacity of the inner cavity of the material box 84 is actually the capacity between the two adjusting plates 874. The amount of quantitative material discharge can be changed by adjusting the distance between the adjusting plates 874. The adjusting plates 874 are fixedly connected to the shielding plate 873. When the material box 84 moves to the material discharge port 83, the EVA foam material in the inner cavity of the material box 84 falls from the middle of the material box 84. At this time, the groove 85 contacts the bottom end of the elastic rod 862. At the same time, under the elastic force of the fourth spring 864, the elastic rod 862 produces a knocking effect on the material box 84, so that the EVA foam material attached to the inner wall of the material box 84 falls to the bottom. The mold cavity on the upper surface of the mold 3 can achieve precise material discharge. When the sizes of slippers to be produced are different, the amount of EVA foam material required is also different. The second threaded rod 871 can be rotated to drive the adjustment block 872 to move. The baffle plate 873 is used to block the gap on the side of the discharge box 84 to prevent the EVA foam material from leaking. The movement of the baffle plate 873 drives the adjustment plate 874 to slide in the inner cavity of the discharge box 84, so that the connecting hole 88 receives the amount of raw materials from the hopper 82 during the movement, thereby achieving quantitative adjustment, making the surface of the produced slippers more complete, and not wasting raw materials.

[0027] In summary, the feeding component 8 is moved to the position of the outer surface of the foaming frame 1, and the EVA foaming material is fed in equal amounts on the mold cavity on the upper surface of the bottom mold 3 through the feeding component 8. After the feeding is completed, the feeding component 8 is moved to the side of the bottom mold 3, and the telescopic table 2 is driven upward by the cylinder at the bottom end of the foaming frame 1 to align the bottom mold 3 and the top mold 5. The guide rod 4 is inserted into the limit groove on the lower surface of the top mold 5. At this time, according to the size of the shoe model 6 and the electric heating pipe in the inner cavity of the top mold 5, the EVA foaming is realized. The material is hot-pressed and formed. When the cylinder contracts, the demoulding assembly 7 can perform a flexible demoulding process on the slippers in the mold cavity of the bottom mold 3, and the flexibility of each slipper is different, which prevents scratches on the outer surface of the hot-pressed slippers. When the bottom mold 3 descends, the lifting mechanism 73 drives the slide plate 71 to slide in the inner cavity of the bottom mold 3, so that the demoulding mechanism 72 performs a flexible demoulding process on the slippers in the mold cavity of the bottom mold 3. The positioning detection mechanism 74 is used to detect whether the bottom mold 3 is offset after long-term use, which is convenient for timely subsequent maintenance. The VA foam material is placed on the upper end of the hopper 82, so that the EVA foam material enters the inner cavity of the discharge box 84. At this time, the discharge box 84 is moved to the upper end of the discharge port 83. At this time, the EVA foam material in the discharge box 84 falls from the discharge port 83 into the cavity of the bottom mold 3 for subsequent hot pressing. By moving the discharge rack 81 on the outer surface of the foaming rack 1, the discharge box 84 is moved on the two discharge ports 83 on the discharge rack 81. Since the capacity of the discharge box 84 is fixed In this way, equal amounts of material can be loaded into the upper mold cavity of the bottom mold 3. During the loading process, the knocking mechanism 86 can knock on the blanking box 84 to prevent the EVA foam material from adhering to the inner wall of the blanking box 84, thereby ensuring the accuracy of equal loading of the EVA foam material. The adjustment mechanism 87 is used to adjust the capacity of the inner cavity of the blanking box 84, which is convenient for adjustment according to the size of the hot-pressed slippers, so that the EVA foam material to be loaded can be quantitatively adjusted according to different hot-pressed slippers, thereby improving production efficiency.
