Abstract
Description
Technical Field
[0001] This invention relates to the field of shoe mold technology, specifically to a shoe mold that facilitates demolding. Background Technology
[0002] Safety shoes are footwear designed to protect the feet. There are many types, such as those that protect toes, prevent punctures, provide insulation, and are resistant to acids and alkalis. The selection of safety shoes should be based on the nature and severity of the hazards in the work environment.
[0003] In the production of safety shoes, the soles need to be cast and molded, usually using specialized shoe molds. The workflow typically involves first spraying a release agent into the mold using a spray gun. After the release agent has completely evaporated, the colloid is injected into the lower mold. Once the colloid is full, the upper mold presses against the lower mold to shape the colloid material within the mold. In the subsequent demolding process, the upper mold is usually manually folded over the lower mold. Because the freshly molded colloid is hot and soft, workers use hook-like tools inserted into the colloid to pull out the molded sole as a whole. This method requires careful consideration of the tool's insertion position to ensure even force distribution across the sole, while the inserted hooks may cause localized damage to the soft sole. This not only makes the operation cumbersome but also affects the subsequent wear quality of the sole.
[0004] Therefore, this invention proposes a shoe mold that facilitates demolding. Summary of the Invention
[0005] The purpose of this invention is to provide a shoe mold that facilitates demolding, thereby solving the problems mentioned in the background section. To achieve the above objective, this invention provides the following technical solution: a shoe mold that facilitates demolding, comprising a cover and a box, wherein an upper mold is disposed inside the cover, and a lower mold is disposed inside the box, and the cover and the box are rotatably connected by a pivot.
[0006] The lower mold has a carrier mold inside, and the carrier mold has concave patterns that match the convex patterns in the upper mold. Two arc-shaped blocks are provided above the lower mold, located at the upper and lower ends of the carrier mold respectively. The upper mold has a groove inside that matches the arc-shaped blocks. The bottom of the carrier mold has a carrier plate. The box body has an ejection unit inside that pushes the carrier plate upward.
[0007] The ejection unit includes a swinging part, which is used to swing the colloid on the lower mold back and forth in the lateral direction.
[0008] The inside of the arc-shaped block is a cavity, and a blade is installed inside the arc-shaped block. The inside of the box body is a separation unit that pushes the blade outward. The separation unit is used to separate the shoe sole from the mold.
[0009] Preferably, the ejection unit includes an annular box located below the carrier plate. The annular box has a ring inside, a connecting shaft inside the ring, a screw inside the connecting shaft, a connecting rod threadedly connected to the outer wall of the screw, the end of the connecting rod being fixedly connected to the inner wall of the box, a motor at the bottom end of the screw, a fixing frame on the outer wall of the motor, a groove on the outer wall of the fixing frame, and one side of the groove being fixedly connected to the inner wall of the box.
[0010] Preferably, the swinging part includes a toothed block located on the outer wall of the ring, the annular box includes a toothed part located on the inner wall of the annular box and meshing with the toothed block, an arc-shaped plate is provided between the carrier mold and the lower mold, the inner wall of the arc-shaped plate is in contact with the outer wall of the carrier mold, and the arc-shaped plate includes a protruding part located inside the lower mold.
[0011] Preferably, the outer wall of the arc-shaped plate and the lower mold have a repulsive magnetic force, and under the action of the magnetic force, the inner wall of the arc-shaped plate and the inner wall of the arc-shaped block are on the same vertical plane.
[0012] Preferably, a cooling air box is provided above the connecting rod, and a transfer box is provided at the air outlet end of the cooling air box. The transfer box includes an outlet one and an outlet two. Two air pipes are provided at the end of the outlet one. The ends of the two air pipes are fixedly connected to the carrier plate. An electromagnet is provided inside the carrier plate. A cylinder is provided above the electromagnet. A sliding column is provided inside the cylinder. The sliding column is located inside the mold and is slidably connected to it.
[0013] Preferably, the sliding column includes a convex portion, and the inner wall of the mold carrier is provided with a magnetic ring. The convex portion and the magnetic ring have a magnetic force that attracts each other. The bottom end of the sliding column is magnetic. When the electromagnet is energized, the electromagnet and the bottom end of the sliding column have a magnetic force that attracts each other, and the magnetic force between the electromagnet and the bottom end of the sliding column is greater than the attraction force between the magnetic ring and the convex portion.
[0014] Preferably, the separation unit includes an air pipe II located at the bottom of the lower mold. The air pipe II is connected to the interior of the arc-shaped block through a channel inside the lower mold. The other end of the air pipe II is connected to the outlet II of the transfer box. The interior of the transfer box is provided with a folding plate. The two folding surfaces of the folding plate are respectively provided with a circular hole I and a circular hole II. A baffle is provided above the transfer box. A top rod is provided below the bottom end of the folding plate. The bottom end of the top rod is fixedly connected to the connecting frame.
[0015] Preferably, when the upper end of the folding plate is raised to contact the inner wall of the baffle, the diameter portions of the second round hole and the second outlet are aligned, and the bottom surface of the shoe sole is aligned with the protruding area of the blade.
[0016] This invention has at least the following beneficial effects:
[0017] 1. In this invention, the motor drives the screw to rotate on the inner wall of the connecting rod, which drives the connecting shaft to lift the ring and the arc box, and finally pushes the molded sole above the carrier plate and the mold to rise until the top surface of the carrier plate and the bottom of the arc plate stop against each other. In this state, the sole will be located protruding from the inside of the lower mold, which makes it easier for workers to safely pick it up and ensures that the molded sole has good quality.
[0018] At the same time, the toothed blocks on the outer wall of the ring will mesh with the toothed part to achieve the reciprocating motion of the sole colloid driven by the mold in the left and right direction. The side of the colloid is lifted to the inner wall of the arc block, and the side of the colloid abuts against the arc block, causing the end of the colloid to detach from the inner wall of the arc plate, reducing the adhesion between the colloid and the inner wall of the arc plate, making it easier to demold and remove the sole.
[0019] 2. In this invention, the magnetic force generated by the electromagnet will cause the sliding column to descend, and the cooling gas can enter the interior of the mold through the first air pipe to cool the colloid. The connecting frame will drive the top rod and the folding plate to rise until the second outlet will be aligned with the second round hole. The gas enters the interior of the arc-shaped block through the second air pipe, causing the blade to extend from the inside. The effect of the swinging part has created a gap between the bottom surface of the colloid and the mold, so that the blade can penetrate into this gap and effectively separate the two. This allows the workers to pick up the shoe sole after it has cooled down, which not only protects the safety of the workers, but also makes the demolding and picking up of the shoe sole more convenient and ensures the demolding quality of the shoe sole.

Detailed Implementation
[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Please see Figure 1-12 The present invention provides a technical solution: a shoe mold that is easy to demold, comprising:
[0035] Example 1,
[0036] The lid 1 and the box 2 are provided. The lid 1 has an upper mold 3 inside and is fixedly connected to it. The box 2 has a lower mold 4 inside and is fixedly connected to it. The lid 1 and the box 2 are rotatably connected by a rotating shaft. The upper mold 3 and the lower mold 4 are pressed together to form the colloid inside the lower mold 4. The above is the prior art, so it will not be described in detail.
[0037] In this design, the lower mold 4 has a carrier mold 5 inside, which has concave patterns that match the convex patterns in the upper mold 3. The carrier mold 5 can be used to receive the colloid to be molded, and the upper mold 3 presses it to form a shoe sole. The lower mold 4 has two arc-shaped blocks 6 above it and is fixedly connected to them. The arc-shaped blocks 6 are located at the upper and lower ends of the carrier mold 5 respectively. The upper mold 3 has a groove 7 inside that matches the arc-shaped blocks 6. The limiting effect between the arc-shaped blocks 6 and the groove 7 can ensure the precise positioning between the upper mold 3 and the lower mold 4 during the mold pressing process and prevent the mold from deviating.
[0038] The bottom of the mold 5 is provided with a carrier plate 8 and is fixedly connected to it. The inside of the box 2 is provided with an ejection unit 9 that pushes the carrier plate 8 upward. The ejection unit 9 includes a swing part 10, which is used to swing the colloid on the lower mold 4 back and forth in the horizontal direction. When the upper mold 3 is opened, the ejection unit 9 takes effect, driving the carrier plate 8 to drive the mold 5 to gradually rise inside the lower mold 4, thereby raising the molded sole above the mold 5 to the top of the lower mold 4, making it convenient for workers to pick it up, reducing damage to the sole during picking up, and ensuring good wearing quality.
[0039] The ejection unit 9 includes an annular box 13 located below the carrier plate 8. The top surface of the annular box 13 is fixedly connected to the carrier plate 8. The annular box 13 has a ring 14 inside and is rotatably connected to it. The ring 14 has a connecting shaft 15 inside and is fixedly connected to it. The connecting shaft 15 has a screw 16 inside and is fixedly connected to it. The outer wall of the screw 16 has a connecting rod 17 threadedly connected to it. The end of the connecting rod 17 is fixedly connected to the inner wall of the box 2. The bottom end of the screw 16 has a motor 18. The screw 16 is connected to the rotating shaft of the motor 18 through a coupling. The outer wall of the motor 18 has a fixing frame 19 and is fixedly connected to it. The outer wall of the fixing frame 19 has a groove 20. The fixing frame 19 slides freely inside the groove 20. One side of the groove 20 is fixedly connected to the inner wall of the box 2. The motor 18 can drive the screw 16 to rotate inside the connecting rod 17, thereby causing the ring 14 at the bottom of the screw 16 to lift the carrier plate 8, ensuring the ejection effect of the mold 5 on the colloid and facilitating the removal of the colloid.
[0040] The swinging part 10 includes a toothed block 21 located on the outer wall of the ring 14. The bottom of the toothed block 21 is fixedly connected to the outer wall of the ring 14. The annular box 13 includes a toothed part 22. There are two rows of toothed parts 22. The toothed parts 22 are located on the inner wall of the annular box 13 and mesh with the toothed block 21. An arc plate 23 is provided between the carrier mold 5 and the lower mold 4. The inner wall of the arc plate 23 is in contact with the outer wall of the carrier mold 5. The arc plate 23 includes a protrusion 24. The protrusion 24 is located inside the lower mold 4 and can slide freely inside the lower mold 4. There is a repulsive magnetic force between the outer wall of the arc plate 23 and the inner wall of the lower mold 4. Under the action of the magnetic force, the inner wall of the arc plate 23 and the inner wall of the arc block 6 are on the same vertical plane, which can realize the precise pressing and positioning between the upper mold 3 and the carrier mold 5.
[0041] When in use, after the sole has been pressed and molded, the staff can open the upper mold 3. At this time, the motor 18 inside the box 2 will start automatically, which will drive the screw 16 to rotate on the inner wall of the connecting rod 17. Due to the threaded connection between the connecting rod 17 and the screw 16, the rotating screw 16 will drive the motor 18 and the connecting frame to gradually rise, which will drive the connecting shaft 15 at the end of the screw 16 to drive the ring 14 and the arc box to rise, and finally push the molded sole above the carrier plate 8 and the carrier mold 5 to rise until the top surface of the carrier plate 8 and the bottom of the arc plate 23 stop against each other. In this state, the sole will be located protruding from the inside of the lower mold 4, which makes it easier for the staff to safely pick it up and ensures that the molded sole has good quality.
[0042] As the carrier plate 8 is lifted, the ring 14 will rotate due to the rotation of the connecting shaft 15. The toothed block 21 on the outer wall of the ring 14 will mesh with the toothed part 22 on the inner wall of the annular box 13, causing the carrier plate 8 to drive the mold 5 and the arc plate 23 to make a slight lateral displacement. When the toothed block 21 meshes with another row of toothed parts 22 of the arc box, the direction of movement of the carrier plate 8 and the attachment above it will also be opposite, thereby realizing the reciprocating movement of the mold 5 and the sole colloid in the left and right directions; until the mold 5 lifts the side of the colloid. When the mold 5 reaches the inner wall of the arc-shaped block 6, the lateral displacement of the mold 5 will cause the side of the colloid to resist the arc-shaped block 6. Under the action of a small displacement, since the displacement distance is very small at this time, it will only cause the colloid to separate from the arc-shaped plate 23. The sole itself has a certain elasticity and can automatically recover after being squeezed, so that the two ends of the colloid gradually separate from the inner wall of the arc-shaped plate 23. This provides favorable conditions for subsequent workers to pick up the colloid, reduces the adhesion between the colloid and the inner wall of the arc-shaped plate 23, and makes the demolding and picking up of the sole easier.
[0043] According to the above embodiments, Embodiment Two
[0044] A cooling air box 25 is provided above the connecting rod 17 and is fixedly connected to it. A transfer box 26 is provided at the air outlet end of the cooling air box 25 and is connected to it. The transfer box 26 includes an outlet 1 27 and an outlet 28. Two air pipes 29 are provided at the end of the outlet 1 27 and are connected to both of them. The ends of the two air pipes 29 are fixedly connected to the carrier plate 8. An electromagnet 30 is provided inside the carrier plate 8 and is fixedly connected to it. A cylinder 31 is provided above the electromagnet 30 and is fixedly connected to it. A sliding column 32 is provided inside the cylinder 31 and is slidably connected to it. The sliding column 32 is located inside the mold 5 and is slidably connected to it. The sliding column 32 includes a convex part 33. A magnetic ring 34 is provided on the inner wall of the mold 5 and is fixedly connected to it. The convex part 33 and the magnetic ring 34 have a magnetic force that attracts each other.
[0045] The bottom end of the sliding column 32 is magnetic. When the electromagnet 30 is energized, the electromagnet 30 and the bottom end of the sliding column 32 have a magnetic force that attracts each other. The magnetic force between the electromagnet 30 and the bottom end of the sliding column 32 is greater than the attraction between the magnetic ring 34 and the convex part 33. This causes the sliding column 32 to descend inside the cylinder 31, allowing the cooling gas inside the air pipe 29 to act on the colloid through the mold 5, so that the colloid is cooled in a spreading manner from both ends, preventing burns when workers pick up the shoe sole.
[0046] The interior of the arc-shaped block 6 is hollow, and a blade 11 is installed inside the arc-shaped block 6. The blade 11 has a folded shape, and the top surface of the vertical area of the blade 11 is in contact with the inner wall of the arc-shaped block 6. The blade 11 slides freely inside the arc-shaped block 6. The box body 2 has a separation unit 12 that pushes the blade 11 outward. The separation unit 12 is used to separate the sole from the mold 5. The separation unit 12 includes an air pipe 35 located at the bottom of the lower mold 4. The air pipe 35 is connected to the interior of the arc-shaped block 6 through a channel inside the lower mold 4. The other end of the air pipe 35 is connected to the outlet 28 of the transfer box 26. The transfer box 26 has a folding plate 36 inside, which slides freely inside the transfer box 26. The two folding surfaces of 36 are respectively provided with a first round hole 37 and a second round hole 38. A baffle 39 is provided above the transfer box 26 and is fixedly connected to it. Both the baffle 39 and the folding plate 36 are L-shaped. A top rod 40 is provided below the bottom end of the folding plate 36. The bottom end of the top rod 40 is fixedly connected to the connecting frame. When the upper end of the folding plate 36 is raised to contact the inner wall of the baffle 39, the diameter of the second round hole 38 is aligned with the diameter of the second outlet 28, and the bottom surface of the shoe sole is aligned with the protruding area of the blade 11. This allows the gas inside the cooling air box 25 to enter the interior of the second air pipe 35 through the second outlet 28 and push the blade 11 inside the arc block 6 to extend into the gap between the bottom surface of the shoe sole and the mold 5, so that the two are effectively separated.
[0047] Before demolding, the mold needs to be pre-vented. At this time, the cooling air box 25 can be activated and the electromagnet 30 can be energized. The magnetic force generated by the electromagnet 30 will cause the sliding column 32 to descend, so that the end of the sliding column 32 no longer blocks the mold 5. The cooling gas can then enter the interior of the mold 5 through the air pipe 29, and finally act on both ends of the colloid, spreading from both ends to the middle area to cool the colloid. It is worth noting that since the cooling starts from both ends of the colloid, the temperature in these two areas will drop first, which reduces the adhesion between the colloid and the arc plate 23. This works in conjunction with the effect of the swing part 10 in the ejection unit 9 to better separate the two ends of the colloid from the arc plate 23, further facilitating the demolding process for the workers.
[0048] After this, as the motor 18 gradually rises, the connecting frame will cause the top rod 40 to abut against the bottom of the folding plate 36 until the top of the folding plate 36 abuts against the inner wall of the baffle 39. At this point, outlet 27 will be blocked by the planar area of the folding plate 36, thus closing the passage for gas to enter the air pipe 29. Simultaneously, outlet 28 will align with the round hole 38, allowing gas to enter the interior of the arc-shaped block 6 through the air pipe 35 and act on the vertical part of the blade 11. The process of gas entering the arc-shaped block 6 is... The gas inflation process takes a short time and the blade 11 will not extend before the bottom surface of the colloid reaches the bottom surface of the arc block 6. The blade 11 extends from the inside. Due to the effect of the swing part 10, a gap has been created between the bottom surface of the colloid and the mold 5. The blade 11 can then penetrate into this gap to effectively separate the two. This allows the staff to pick up the sole after it has cooled down, which not only protects the safety of the staff but also makes the demolding and picking up of the sole more convenient and ensures the demolding quality of the sole.
