Description

Technical Field

[0001] This application relates to the field of mold design technology, and in particular to a shoe forming mold, device and method. Background Technology

[0002] When manufacturing shoes, the various parts of the shoe (such as the sole, upper, and heel) are usually shaped using molds, and this process may involve using various materials and different manufacturing processes.

[0003] In related technologies, shoe molding dies typically involve injection, pressure holding, cooling, and demolding during shoe manufacturing. Problems can arise during demolding (e.g., uneven stress on the shoe before demolding, friction during demolding, or air bubbles within the mold). Poor demolding can lead to surface defects or structural inconsistencies, resulting in shoe damage, increased scrap rates, and consequently, low production efficiency. Summary of the Invention

[0004] This application provides a shoe molding mold, apparatus, and method, which can improve the technical problem in the related art where shoe surface defects and uneven structure damage caused by poor demolding lead to an increased scrap rate.

[0005] In a first aspect, embodiments of this application provide a shoe forming mold, comprising:

[0006] An auxiliary outer mold includes a first half-mold and a second half-mold, the first half-mold and the second half-mold being able to interlock to form a receiving space, and the first half-mold having a plurality of air extraction holes communicating with the receiving space; and

[0007] The forming inner mold includes an upper mold part and a lower mold part, which can be interlocked to form a shoe cavity; the lower mold part has multiple vent holes communicating with the shoe cavity;

[0008] The inner mold is rotatably disposed within the accommodating space, such that the vent hole is connected to the suction hole, or the vent hole and the suction hole are offset from each other and not connected.

[0009] The technical solutions described in this application embodiment have at least the following technical effects:

[0010] The shoe molding mold provided in this application allows for the following steps when demolding: First, the inner mold is rotated within the accommodating space. As the lower mold rotates, it drives the vent to rotate, and the vent rotates to the extraction port, connecting the vent and extraction ports. This facilitates the discharge of gas from the shoe cavity. After the vent is exhausted, the first and second half molds are opened, followed by the upper and lower molds. Finally, the molded shoe is removed. During demolding, the first and second half molds protect the shoe from external vibrations, forces, or temperatures, reducing the risk of damage due to structural instability. Rotation connects the extraction and vent ports, allowing gas to escape from the inner mold, increasing the likelihood of defects on the shoe surface, improving aesthetics, and increasing the pass rate, thus improving work efficiency.

[0011] In some embodiments, the forming inner mold further includes a plurality of fasteners; a plurality of first fastening holes are respectively opened on both sides of the upper mold, and a plurality of second fastening holes are respectively opened on both sides of the lower mold; when the upper mold and the lower mold are engaged, the plurality of first fastening holes correspond one-to-one with the plurality of second fastening holes; the plurality of fasteners are connected one-to-one with the plurality of first fastening holes and the plurality of second fastening holes.

[0012] When tightening each of the fasteners, the middle fastener is tightened first, and then the fasteners on both sides of the middle fastener are tightened diagonally. When loosening each of the fasteners, the fasteners on both sides of the middle fastener are loosened diagonally first, and then the middle fastener is loosened.

[0013] In some embodiments, an upper connecting portion is provided on one side of the upper mold; a lower connecting portion is provided on one side of the lower mold; when the upper mold and the lower mold are engaged, the upper connecting portion and the lower connecting portion engage to form a mounting portion.

[0020] The shoe molding apparatus provided in this application embodiment, when it is necessary to demold the molded shoe, drives the inner mold in the first space to rotate within the receiving space. When the lower mold rotates, it can drive the vent to rotate, and the lower mold drives the vent to rotate to the air extraction hole, so that the vent and air extraction holes are connected. This facilitates the discharge of gas in the shoe cavity through the vent, enhances the structural uniformity of the shoe after demolding, and reduces the defects on the shoe surface caused by gas generated in the shoe cavity. After the vent is exhausted, the shoe demolding apparatus drives the first half mold and the second half mold to open. Finally, the upper mold and the lower mold are separated by an auxiliary device to remove the molded shoe. The first half mold and the second half mold can protect the upper mold and the lower mold to maintain stability, thereby reducing the possibility of damage to the shoe due to instability. The separation of the upper mold and the lower mold by the auxiliary device improves the uniformity of force during demolding, increases the possibility of no defects on the shoe surface in the inner mold, and further improves the pass rate of the shoe, thereby improving work efficiency.

[0079] When manufacturing shoes, the various parts of the shoe (such as the sole, upper, and heel) are usually shaped using molds, and this process may involve using various materials and different manufacturing processes.

[0080] In related technologies, shoe molding dies typically involve injection, pressure holding, cooling, and demolding during shoe manufacturing. Problems can arise during demolding (e.g., uneven stress on the shoe before demolding, friction during demolding, or air bubbles within the mold). Poor demolding can lead to surface defects or structural inconsistencies, resulting in shoe damage, increased scrap rates, and consequently, low production efficiency.

[0081] Based on this, in order to improve the problem in related technologies that shoe surface defects and uneven structure damage caused by poor demolding, resulting in an increased scrap rate, the embodiments of this application provide the following solutions.

[0082] Please refer to the following: Figure 2 and Figure 3 This application provides a shoe forming mold 20, which includes an auxiliary outer mold 21 and a forming inner mold 22, wherein:

[0083] The auxiliary outer mold 21 includes a first half mold 211 and a second half mold 212. The first half mold 211 and the second half mold 212 can be interlocked to form a receiving space. The first half mold 211 has a plurality of air extraction holes 21101 connected to the receiving space.

[0084] The inner mold 22 includes an upper mold part 221 and a lower mold part 222, which can be interlocked to form a shoe cavity. The lower mold part 222 has multiple vent holes 22201 that communicate with the shoe cavity.

[0085] The inner mold 22 is rotatably disposed within the accommodating space so that the vent 22201 is connected to the air extraction hole 21101, or the vent 22201 and the air extraction hole 21101 are staggered and not connected.

[0086] It is understood that the first half-mold 211 can be a structure capable of accommodating and protecting the upper mold part 221, such as a semi-cylindrical shell structure, but is not limited thereto; the second half-mold 212 can be a structure capable of accommodating and protecting the lower mold part 222, such as a semi-cylindrical shell structure, but is not limited thereto. The upper mold part 221 and the lower mold part 222 are structures used for shoe molding and enabling easy demolding of the molded shoe parts, such as semi-cylindrical structures, but are not limited thereto. The shoe cavity is a cavity that accommodates the shoe material.

[0087] As can be seen from the above, when the shoe mold 20 provided in this application needs to demold the molded shoe, the inner mold 22 is first rotated within the accommodating space; when the lower mold 222 rotates, it can drive the vent 22201 to rotate, and the lower mold 222 drives the vent 22201 to rotate to the air extraction hole 21101, so that the vent 22201 and the air extraction hole 21101 are connected, which can facilitate the gas in the shoe cavity to be discharged through the vent 22201, reducing the defects on the shoe surface caused by the gas generated in the shoe cavity; after the vent 22201 is discharged, the first half mold 211 and the second half mold 212 are first opened. Open the mold, then open the upper mold 221 and the lower mold 222, and finally take out the molded shoe. During demolding, the first half mold 211 and the second half mold 212 can protect the shoe inside the upper mold 221 and the lower mold 222 from external vibration, force or temperature, thereby reducing the possibility of damage to the shoe due to structural instability. The air extraction hole 21101 and the exhaust hole 22201 can be connected by rotation, and the gas can be discharged from the exhaust hole 22201 to the outside of the molding inner mold 22, thereby increasing the possibility of no defects on the surface of the shoe in the molding inner mold 22, improving the aesthetics of the shoe, and further improving the pass rate of the shoe, so as to improve work efficiency.

[0088] In some embodiments, please refer to Figure 4 The inner mold 22 also includes multiple fasteners 223; multiple first fastening holes are respectively opened on both sides of the upper mold 221, and multiple second fastening holes are respectively opened on both sides of the lower mold 222. When the upper mold 221 and the lower mold 222 are engaged, the multiple first fastening holes correspond one-to-one with the multiple second fastening holes. The multiple fasteners 223 are connected one-to-one with the multiple first fastening holes and the multiple second fastening holes.

[0089] When tightening each fastener 223, first tighten the middle fastener 223, and then tighten the fasteners 223 on both sides of the middle fastener 223 diagonally. When loosening each fastener 223, first loosen the fasteners 223 on both sides of the middle fastener 223 diagonally, and then loosen the middle fastener 223.

[0090] It is understood that the fastener 223 is a component that can stably connect the upper mold 221 and the lower mold 222 after fastening the first fastening hole and the second fastening hole. For example, it can be a bolt, but is not limited to this.

[0091] For example, the upper mold 221 has first fastening holes on both sides, such as five first fastening holes on each side of the upper mold 221, with the first fastening holes on both sides facing each other, but not limited to this; the lower mold 222 has second fastening holes on both sides, such as five second fastening holes on each side of the lower mold 222, with the first fastening holes on both sides facing each other, but not limited to this; for example, the fastening component in the middle of one side and the fastening component in the middle of the other side of the upper mold 221 are defined as the first fastening component (each side has one in the middle) There are four fastening components: one on each side (two on each side), two on each side of the first fastening component, four on each side of the first fastening component, and four on each side of the second fastening component. The lower mold 222 and the upper mold 221 have the same number and definition. When fastening components are tightened, the first fastening component is tightened first (diagonally), then the second fastening component is tightened (diagonally), and finally the third fastening component is tightened (diagonally). When loosening fastening components (a preset loosening value can be set; when the loosening force equals the preset value on the fastening component, it indicates that the fastening force of the fastening component has been lost, and the inner mold 22 can be opened), the third fastening component is loosened first (diagonally), then the second fastening component is loosened (diagonally), and finally the first fastening component is loosened. Diagonal loosening can involve first loosening one fastener on one side, then loosening another fastener on the other side (which needs to be diagonally opposite to the fastener on one side), but it is not limited to this. This embodiment only illustrates the case where there are 10 fasteners (5 on each side). The same method applies to cases with 6, 8, 12, or more fasteners.

[0092] With this configuration, when the molded shoe needs to be demolded, the inner mold 22 is first rotated within the receiving space. The rotation of the lower mold 222 causes the vent 22201 to rotate, and the lower mold 222 rotates the vent 22201 to the suction port 21101, connecting the vent 22201 with the suction port 21101. Once the vent 22201 has finished venting, the first half mold 211 and the second half mold 212 are opened. When opening the upper mold 221 and the lower mold 222, the fasteners 223 on each of the first and second fastening holes need to be loosened. This is because the upper mold 221 has multiple first fasteners 223 on both sides, and the lower mold 222 has multiple second fasteners 223 on both sides. 223 is connected to multiple first fastening holes and multiple second fastening holes in a one-to-one correspondence. Therefore, first loosen the fasteners 223 on both sides away from the middle fastener 223 diagonally, and then loosen the middle fastener 223. After loosening each fastener 223 on each first fastening hole and each second fastening hole, open the upper mold 221 and the lower mold 222 to remove the molded shoe. During demolding, the cooperation of the first fastening holes, the second fastening holes and the fasteners 223 helps the upper mold 221 and the lower mold 222 to be evenly stressed when they separate, thereby reducing uneven stress on the shoe and making demolding of the shoe more convenient and faster. This reduces defects on the surface of the shoe and further improves the pass rate of the shoe.

[0093] Optionally, in some embodiments, please refer to Figure 3 An upper connecting portion 2211 is provided on one side of the upper mold 221. A lower connecting portion 2221 is provided on one side of the lower mold 222; when the upper mold 221 and the lower mold 222 are engaged, the upper connecting portion 2211 and the lower connecting portion 2221 engage to form a mounting portion 224.

[0094] It is understood that the upper connecting part 2211 and the lower connecting part 2221 can be structures capable of connecting other components, such as a semi-cylindrical structure, but are not limited thereto. The mounting part 224 is a cylindrical structure formed by the interlocking of the upper connecting part 2211 and the lower connecting part 2221, but is not limited thereto.

[0095] With this configuration, when the molded shoe needs to be demolded, the upper mold part 221 and the lower mold part 222 are interlocked, and the upper connecting part 2211 and the lower connecting part 2221 form the mounting part 224. The rotation of the mounting part 224 drives the upper mold part 221 and the lower mold part 222 to rotate. When the lower mold part 222 rotates, it drives the vent hole 22201 to rotate, and the lower mold part 222 drives the vent hole 22201 to rotate to the air extraction hole 21101, so that the vent hole 22201 and the air extraction hole 21101 are connected. After the vent hole 22201 has exhausted its air, the first half mold 211 and the second half mold 222 are first demolded. Open the two halves of the mold 212, loosen the fasteners 223 on both sides away from the middle fastener 223 diagonally, then loosen the middle fastener 223. After loosening, open the upper mold 221 and the lower mold 222 to finally remove the molded shoe. During demolding, the mounting part 224 drives the inner mold 22 to rotate, and then the mounting part 224 is assembled by the interlocking of the upper mold 221 and the lower mold 222, making the structure more compact, simplifying the installation steps, reducing the stress on the upper mold 221 and the lower mold 222, reducing the problem of defects on the surface of the shoe, and thus improving the pass rate of the shoe.

[0097] The housing 10 has a first space 1101, a second space 1102 and a connecting port 1103, and the first space 1101 is located above the second space 1102; the first space 1101 is connected to the second space 1102 through the connecting port 1103.

[0098] The shoe forming mold 20 is set in the first space 1101.

[0100] The auxiliary device 40 is located within the first space 1101 and the second space 1102, and is disposed on the inner wall of the housing 10. The auxiliary device 40 is used to assist in demolding when the shoe demolding device 30 is demolded.

[0101] It is understood that the shoe demolding device 30 is a device capable of demolding the molded material. For example, it may be a component that assists in opening the inner mold 22 or evacuates air from the shoe cavity inside the inner mold 22, but is not limited to this. The shoe mold 20 is a component capable of molding the material and protecting the shoe from damage, but is not limited to this. The auxiliary device 40 is a component capable of making the demolding force more uniform during demolding of the shoe mold 20, but is not limited to this.

[0102] As can be seen from the above, when the shoe molding apparatus 100 provided in this application needs to demold the molded shoe, since the upper connecting part 2211 of the upper mold part 221 and the lower connecting part 2221 of the lower mold part 222 are engaged to form the mounting part 224, the shoe demolding device 30 drives the mounting part 224 in the first space 1101 to rotate. At this time, the upper mold part 221 and the lower mold part 222 rotate. When the lower mold part 222 rotates, it can drive the vent hole 22201 to rotate. When the vent hole 22201 rotates to the air extraction hole 21101, the vent hole 22201 is connected to the air extraction hole 21101. After the vent hole 22201 has finished venting, the shoe demolding device 30 first opens the first half mold 211 and the second half mold 212. Next, separate the upper mold 221 and the lower mold 222. When separating the upper mold 221 and the lower mold 222, loosen the fasteners 223 on each of the first fastening holes and each of the second fastening holes. Loosen the fasteners 223 on both sides away from the middle fastener 223 diagonally, and then loosen the middle fastener 223. The upper mold 221 and the lower mold 222 are then opened to remove the molded shoe. The vent 22201 is connected to the air extraction hole 21101, which allows the gas in the shoe cavity to be discharged through the vent 22201. This reduces the possibility of defects on the surface of the shoe due to gas or air bubbles in the shoe cavity. It also improves the uniform force distribution during demolding, further increasing the pass rate of the shoe and improving work efficiency.

[0103] Optionally, in some embodiments, please refer to Figure 1 The shoe demolding device 30 includes a pretreatment mechanism 31, an air extraction mechanism 32, and an adjustment mechanism 33, wherein:

[0104] The pretreatment mechanism 31 is located within the first space 1101. One end of the pretreatment mechanism 31 is disposed on the inner side wall of the housing 10, and the other end of the pretreatment mechanism 31 is disposed on the auxiliary outer mold 21.

[0105] The air extraction mechanism 32 is located at the bottom of the housing 10 and below the auxiliary outer mold 21; the air extraction mechanism 32 is connected to the air extraction hole 21101.

[0106] The adjustment mechanism 33 is disposed on the inner wall of the housing 10 and is located above the suction mechanism 32. The power output end of the adjustment mechanism 33 passes through the auxiliary outer mold 21 and is connected to the mounting part 224 on the molding inner mold 22. The adjustment mechanism 33 is used to drive the molding inner mold 22 to rotate.

[0107] It is understood that the pretreatment mechanism 31 is a component capable of moving the auxiliary outer mold 21, such as an electrically driven moving component, but not limited to this. The air extraction mechanism 32 is a component capable of extracting air bubbles or gas from the molding inner mold 22, such as a component consisting of an air extraction component and an air extraction pipe, but not limited to this. The adjustment mechanism 33 can be a component capable of adjusting the position of the molding inner mold 22 within the accommodating space, such as a motor and a drive shaft, but not limited to this.

[0108] With this setup, when the molded shoes need to be demolded, the upper mold 221 and lower mold 222 interlock to form the mounting part 224. The shoe demolding device 30 drives the mounting part 224 in the first space 1101 to rotate. At this time, the upper mold 221 and lower mold 222 rotate. When the vent 22201 rotates to the air extraction hole 21101, the vent 22201 connects with the air extraction hole 21101, and the air extraction mechanism 32 extracts the gas or air bubbles from the molding inner mold 22. After the air extraction mechanism 32 has extracted the gas, the pretreatment mechanism 31 drives the first half mold 211 and the second half mold 222 to rotate. The half mold 212 is moved and opened, and then the fasteners 223 on each of the first fastening holes and each of the second fastening holes are loosened. After the fasteners 223 are loosened, the upper mold 221 and the lower mold 222 are evenly separated by the auxiliary device 40 to remove the molded shoe. Through the cooperation of the pretreatment mechanism 31, the adjustment mechanism 33 and the air extraction mechanism 32, the force generated on the molding inner mold 22 can be reduced, thereby improving the uniformity of the shoe structure and reducing the possibility of surface defects caused by force. The shoe can be easily and quickly removed from the molding inner mold 22 without damage, thereby improving work efficiency.

[0109] Optionally, in some embodiments, please refer to Figure 1 and Figure 2 The pretreatment mechanism 31 includes a first processing component 311 and a second processing component 312, wherein:

[0110] The first processing component 311 is located within the first space 1101; the first processing component 311 includes a first fixed rod 3111 and a first movable rod 3112; the first fixed rod 3111 is fixedly disposed on the inner side wall of the housing 10. One end of the first movable rod 3112 is movably connected to the first fixed rod 3111, and the other end of the first movable rod 3112 is fixedly connected to the second half mold 212.

[0111] The second processing component 312 is located within the first space 1101 and below the first processing component 311. The second processing component 312 includes a second fixed rod 3121 and a second movable rod 3122. The second fixed rod 3121 is fixedly disposed on the inner side wall of the housing 10. One end of the second movable rod 3122 is movably connected to the second fixed rod 3121, and the other end of the second movable rod 3122 is fixedly connected to the first half mold 211.

[0112] The first movable rod 3112 can rotate relative to the first fixed rod 3111 to either a first retracted state or a first working state. When the first movable rod 3112 switches from the first working state to the first retracted state, the second half-mold 212 moves upward away from the first half-mold 211 until it is parallel to the side wall of the housing 10.

[0113] The second movable rod 3122 can rotate relative to the second fixed rod 3121 to either a second retracted state or a second working state. When the second movable rod 3122 switches from the second working state to the second retracted state, the first half-mold 211 moves downward away from the second half-mold 212 until it is parallel to the side wall of the housing 10.

[0114] It is understood that the first movable rod 3112 can be a component capable of driving and supporting the movement of the second half-mold 212, such as a plate-like structure or a rod-like structure, but is not limited thereto. The second movable rod 3122 can be a component capable of driving and supporting the movement of the first half-mold 211, such as a plate-like structure or a rod-like structure, but is not limited thereto. The first fixed rod 3111 can be a component capable of driving the first movable rod 3112, such as including a connecting wheel (which can be a wheel, etc.) and a drive motor for driving the rotating wheel to rotate, the drive motor can be a motor, etc., but is not limited thereto. The second fixed rod 3121 can be a component capable of driving the second movable rod 3122, such as including a rotating wheel (which can be a gear, etc.) and a drive motor for driving the rotating wheel to rotate, the drive motor can be a rotary motor, etc., but is not limited thereto.

[0115] With this configuration, after the gas extraction mechanism 32 has extracted the gas, the first movable rod 3112 needs to be switched from the first working state to the first retracted state. The first fixed rod 3111 drives the first movable rod to rotate upward, and the first movable rod 3112 drives the second half-mold 212 to move. The second half-mold 212 moves upward away from the first half-mold 211 until it is parallel to the side wall of the housing 10. At the same time, the second movable rod 3122 switches from the second working state to the second retracted state. The second fixed member drives the second movable rod to rotate downward, and the second movable rod 3122 drives the first half-mold 211 to move. Therefore, the second half-mold 212 moves downward away from the first half-mold 211 until it is parallel to the side wall of the housing 10. The side walls are parallel; the first half mold 211 is in the first closed state, and the second half mold 212 is in the second closed state. Driven by the first processing component 311 and the second processing component 312, the first half mold 211 and the second half mold 212 can be opened simultaneously in a convenient and quick manner. The force on the first half mold 211 and the second half mold 212 when they are opened is small, which reduces the force on the mold in the inner mold 22 of the accommodating space and makes the force more uniform. This avoids the problem of defects on the surface of the shoe due to gas in the shoe cavity of the inner mold 22, and to a certain extent avoids damage to the shoe structure, ensures the quality of the molded shoe, and thus improves the pass rate of the shoe.

[0116] Optionally, in some embodiments, please refer to Figure 5 The vacuum mechanism 32 includes a vacuum pump 321, a connector 322, and multiple vacuum branch pipes 323. The vacuum pump 321 is located within the second space 1102 and is mounted on the bottom wall of the housing 10. One end of the connector 322 is connected to the vacuum pump 321. One end of each vacuum branch pipe 323 is connected to the other end of the connector 322, and the other end of the vacuum branch pipe 323 is connected to the vacuum port 21101. Each vacuum branch pipe 323 corresponds one-to-one with a vacuum port 21101. The vacuum pump 321, connector 322, and vacuum branch pipes 323 are all located below the first half-mold 211.

[0117] It is understood that the vacuum pump 321 can be a component capable of extracting air bubbles or gas from the inner mold 22, such as a vacuum pump, but is not limited to this. The connector 322 can be a component capable of extracting gas from the connector 322 using the vacuum pump 321, and can be a tubular structure, but is not limited to this. The vacuum branch pipe 323 can be a pipe pile structure connecting the vacuum hole 21101 and the connector 322, but is not limited to this.

[0118] With this configuration, to prevent air bubbles from forming in the shoe cavity after the injection molding material is added, the upper mold part 221 and the lower mold part 222 are interlocked, forming the mounting part 224. The rotation of the mounting part 224 drives the upper mold part 221 and the lower mold part 222 to rotate. When the lower mold part 222 rotates, it drives the vent hole 22201 to rotate. When the lower mold part 222 rotates the vent hole 22201 to the suction hole 21101, the vent hole 22201 connects with the suction hole 21101. At this time, the suction branch pipe 323 connects to the vent hole 22201. Since one end of the connector 322 is connected to the vacuum pump 321, and one end of the suction branch pipe 323 is connected to the other end of the connector 322, the vacuum pump 321 is connected to the suction branch pipe 323 through the connector 322. When the extraction pipe 323 is in operation, the vacuum pump 321 extracts the gas from the inner mold 22. The gas in the inner mold 22 is extracted from the vent 22201 of the lower mold part 222. The extracted gas is drawn through the extraction hole 21101 of the first half mold 211 into the extraction pipe 323, and then input into the vacuum pump 321 through the connector 322, thereby extracting the gas from the inner mold 22 so that the inner mold 22 is not affected by the gas when the mold is opened. By extracting the gas with the vacuum pump 321, the damage to the shoe due to air bubbles during mold opening can be reduced, thereby improving the stability of the shoe structure. The vacuum pump 321 can accurately extract the gas from the inner mold 22, which can reduce the occurrence of defects on the surface or bottom of the shoe to a certain extent, improve the pass rate of the shoe, reduce the waste of resources, and further improve work efficiency.

[0119] Optionally, in some embodiments, please refer to Figure 7 The bottom of the shoe mold cavity has a textured pattern. The textured pattern includes multiple protrusions 2242 and multiple recesses 2243. Air inlets 224201 are provided on the protrusions 2242. The lower mold 222 has a vent 2222 inside that mates with the shoe mold textured pattern. The side wall of the vent 2222 has an air vent 222201. The vent 2222 is located within and communicates with the protrusions 2242 of the textured pattern. The suction mechanism 32 also includes a vent pipe 333. One end of the vent pipe 333 is connected to the suction machine 321, and the other end is connected to the air vent 222201.

[0120] It can be understood that the pattern or texture on the bottom of the shoe is composed of multiple protrusions 2242 and multiple concave parts 2243. The protrusions 2242 on the bottom of the shoe cavity cooperate with the concave parts 2243 on the bottom of the shoe cavity, and vice versa. The pattern provides grip and anti-slip performance to the sole, ensuring sufficient support when walking on different surfaces. The ventilation element 2222 is capable of blowing air into the shoe cavity through the protrusions 2242 on the bottom of the shoe cavity. For example, the air inlet 224201 is also provided with an air inlet cover, which is a structure that closes the air inlet 224201 when the venting component 2222 is not venting. This cover may include, for example, an electrically operated left half cover and an electrically operated right half cover. When the venting component 2222 is working, the electrically operated left half cover and the electrically operated right half cover are open; when the venting component 2222 is not working, the electrically operated left half cover and the electrically operated right half cover are closed, etc., but are not limited to this. The vent pipe 333 may be a tubular structure capable of conveying gas from the vacuum pump 321 through the air inlet 224201 to the shoe cavity, etc., but is not limited to this.

[0121] With this setup, when the molded shoe needs to be demolded, the first half-mold 211 is in the first working state, and the second half-mold 212 is in the second working state. At this time, the vacuum pump 321 is controlled to blow air, and the vacuum pump 321 inputs the gas into the vent pipe 333. The vent pipe 333 delivers the gas through the air inlet 224201 into the shoe cavity. As the gas enters the shoe cavity, due to the gas's pressure, the sole position within the shoe cavity is pushed upwards by the gas, causing the molded shoe to be blown from the bottom of the shoe cavity. Since the upper mold part 221 and the lower mold part 222 have not yet been disassembled, the bottom of the shoe, which is fixed within the shoe cavity, is blown open by the gas (in a non-fixed state). After being blown open, the vacuum pump 321 stops blowing air, and the first half-mold 211 is switched from the first working state to the first retracted state, and the second half-mold 212 is switched from the second working state. In the second closed state, the fasteners 223 are disassembled in sequence, and finally the upper mold 221 and lower mold 222 are opened. The formed shoe can be easily removed without manual force from the shoe cavity, saving time and effort. The cooperation of multiple protrusions and concave parts allows gas to enter the concave parts through the protrusions, which helps to push the shoe parts more evenly and synchronously, thereby improving the stability and safety when removing the shoe and reducing the possibility of damage during the process. This also makes it easier and faster to remove the formed shoe, reducing the possibility of damage to the bottom of the shoe or even the separation of the bottom and top due to excessive force, or the inability to remove the shoe due to insufficient force. By using gas to evenly push out the formed shoe, the pass rate of the shoe is further improved, and the scrap rate is greatly reduced, thereby improving work efficiency.

[0122] Optionally, in some embodiments, please refer to Figure 1 The adjustment mechanism 33 includes a power component 331 and an adjustment shaft 332. The power component 331 is disposed on the inner side wall of the housing 10, located on one side of the auxiliary outer mold 21. One end of the adjustment shaft 332 is connected to the power output shaft of the power component 331, and the other end of the adjustment shaft 332 is connected to the mounting part 224. The power component 331 is used to drive the molding inner mold 22 to rotate within the receiving space via the adjustment shaft 332 to adjust the position of the molding inner mold 22.

[0123] It is understood that the power component 331 can be a component capable of driving the adjusting shaft 332 to rotate and thus rotating the molding inner mold 22, such as a rotary motor, but not limited to this. The adjusting shaft 332 can be a shaft-like structure capable of driving the molding inner mold 22 to rotate under the drive of the power component 331, but not limited to this. For example, the vent 22201 and the suction vent 21101 may differ by a certain angle clockwise (which may be greater than 0° and less than 360°) or a certain angle counterclockwise (which may be greater than 0° and less than 360°). For example, the direction and angle values ​​may be preset values, and when the power component 331 works, it will drive according to the preset angle and direction, but not limited to this. The adjusting shaft 332 may be capable of rotating by a certain angle (which may be greater than 0° and less than 360°) under the drive of the power component 331. For example, multiple locking parts 3321 on the adjusting shaft 332 may be circumferentially spaced around the axis of the adjusting shaft 332 (there may be 4 of them, and they may be perpendicular to the height direction of the housing 10). Multiple bayonet parts 2241 (the number of bayonet parts 2241 can be 4) correspond one-to-one with multiple bayonet mating parts 3321, etc., but not limited to this.

[0124] With this configuration, when the molded shoe needs to be demolded, the upper mold 221 and the lower mold 222 are engaged, and the upper connecting part 2211 of the upper mold 221 and the lower connecting part 2221 of the lower mold 222 are engaged to form the mounting part 224. The adjusting shaft 332 is then mounted on the mounting part 224. One end of the adjusting shaft 332 is connected to the power output shaft of the power component 331. At this time, the power component 331 drives the adjusting shaft 332 to rotate according to the preset value and preset direction. Since the other end of the adjusting shaft 332 is connected to the mounting part 224, the mounting part 224 is also driven to rotate. At this time, the upper mold 221 and the lower mold 222 rotate within the accommodating space. The lower mold 222 drives the vent 22201 to rotate and connects the vent 22201 with the air extraction hole 21101 on the first half mold 211 to perform air extraction. When the inner mold 22 is not demolded, the power component 331 does not drive the adjustment component to move. The vent 22201 and the air extraction hole 21101 are offset. The outer side wall of the lower mold 222 is in contact with the inner side wall of the first half mold 211. The vent 22201 and the air extraction hole 21101 are not connected. At this time, the holes are in a sealed state. The inner mold 22 is rotated by the power component 331 and the adjustment component. The cooperation of the power component 331 and the adjustment component makes the vent 22201 and the air extraction hole 21101 more accurately connected or offset. When not demolded, this prevents external gas from entering the inner mold 22, thereby reducing the possibility of defects on the surface of the shoe or causing unevenness in the structure of the shoe. This improves the integrity of the shoe mold opening, enhances the safety of the environment before demolding, further improves the stability of the shoe structure, and increases the pass rate of the shoe.

[0125] Optionally, in some embodiments, please refer to Figure 3 and Figure 6 The mounting part 224 has multiple bayonet portions 2241. These bayonet portions 2241 are circumferentially spaced around the axis of the mounting part 224. The adjustment mechanism 33 also includes multiple bayonet mating portions 3321. These bayonet mating portions 3321 are circumferentially spaced around the axis of the adjustment shaft 332. Each bayonet portion 2241 corresponds to one of the multiple bayonet mating portions 3321.

[0126] It is understood that the bayonet portion 2241 can be a structure capable of mounting the adjustment shaft 332 onto the mounting portion 224, such as a groove or a protrusion, but is not limited thereto. The bayonet mating portion 3321 can be a structure capable of connecting and securely connecting with the mounting portion 2241 via the bayonet portion 2241, such as a protrusion or a recess, but is not limited thereto. For example, when multiple bayonet portions 2241 and multiple bayonet mating portions 3321 mate, a "click" sound can be emitted, indicating that the multiple bayonet portions 2241 and multiple bayonet mating portions have completed their mating and that the adjustment shaft 332 is accurately installed within the mounting portion 224.

[0127] For example, the bayonet mating part 3321 may include a mating part body and a reset member. The adjusting shaft 332 has a groove, which corresponds one-to-one with the bayonet part 2241. One end of the reset member is fixedly disposed on the bottom of the mating part body, and the other end of the reset member is fixedly disposed on the bottom wall of the groove on the adjusting shaft 332. When the adjusting shaft 332 needs to be installed on the mounting part 224, the mating part body has not yet entered the bayonet part 2241. At this time, the mating part body is subjected to a compressive force, which compresses the reset member. The mating part is squeezed into the groove on the adjusting shaft 332. When the mating part body is located at the bayonet part 2241 (the mating part body corresponds to the bayonet part 2241), the mating part body is no longer subjected to a compressive force, and the reset member is no longer compressed. The reset member pushes the mating part body out of the groove on the adjusting shaft 332 and pushes it into the bayonet part 2241 on the mounting part 224 to complete the connection. The reset member may be a spring, etc., but is not limited to this.

[0128] With this configuration, when the molded shoe needs to be demolded, the upper mold part 221 and the lower mold part 222 interlock, forming an installation part 224 by interlocking the upper connecting part 2211 of the upper mold part 221 and the lower connecting part 2221 of the lower mold part 222. The installation part 224 has multiple locking parts 2241, and multiple locking mating parts 3321 are circumferentially spaced around the axis of the adjusting shaft 332, corresponding one-to-one with the multiple locking parts 2241. One side of the adjusting shaft 332 (the side with the locking mating parts 3321) is installed on the installation part 224, so that each locking mating part 3321 is located within a locking part 2241. The adjusting shaft 332 is locked in place, making it an integral part of the forming inner mold 22. Then, the power component 331 drives the adjusting shaft 332 and the forming inner mold 22 to rotate within the accommodating space. Through the cooperation of the locking part 2241 and the locking mating part 3321, the stability of the forming inner mold 22 during rotation within the accommodating space is improved, and the connection stability between the mounting part 224 and the adjusting shaft 332 is enhanced. The forming inner mold 22 can be automatically adjusted to the required position by the power component 331 and the adjusting shaft 332, reducing manual operation steps, greatly improving the accuracy of angle and position, saving a lot of manpower and time, and enhancing work efficiency.

[0129] Optionally, in some embodiments, please refer to Figure 1 The auxiliary device 40 includes a first auxiliary component 41 and a second auxiliary component 42, wherein:

[0130] The first auxiliary component 41 is located within the first space 1101 and is disposed on the inner top wall of the housing 10. The first auxiliary component 41 faces the second half mold 212.

[0131] The second auxiliary component 42 is located within the second space 1102 and is disposed on the inner bottom wall of the housing 10. The second auxiliary component 42 extends partially into the first space 1101 and faces the first half mold 211; the first auxiliary component 41 and the second auxiliary component 42 are disposed facing each other.

[0132] In the first retracted state, the first auxiliary component 41 is used to clamp the upper mold component 221; in the second retracted state, the second auxiliary component 42 is used to support the lower mold component 222.

[0133] It is understood that the first auxiliary component 41 can be such that when the upper mold 221 is removed, the force applied by the first auxiliary component 41 can contact the top of the upper mold 221, for example, its internal structure can be a structure that evenly clamps the upper mold 221, but it is not limited to this. The second auxiliary component 42 can be such that it can contact the bottom of the lower mold 222, and the force can be evenly distributed on the first auxiliary component 41 when the lower mold 222 is opened, for example, its internal structure can be a structure that supports and lifts the upper mold 221, but it is not limited to this. For example, the shape of the second auxiliary component 42 can be a semi-cylindrical structure that matches the shape of the bottom of the lower mold 222, but it is not limited to this.

[0134] With this configuration, when the first movable rod 3112 switches from the first working state to the first retracted state, the first movable rod 3112 drives the second half mold 212 to move, and the second half mold 212 moves upward away from the first half mold 211 until it is parallel to the side wall of the housing 10; when the second movable rod 3122 switches from the second working state to the second retracted state, the second movable rod 3122 drives the first half mold 211 to move, and the first half mold 211 moves downward away from the second half mold 212 until it is parallel to the side wall of the housing 10; at this time, the inner mold 22 is exposed, and after the fasteners 223 are loosened to less than the preset value, the second auxiliary component 42 located in the second space 1102 moves upward and moves to the position of the lower mold component 222, so that the second auxiliary component 42 contacts the lower mold component 222 to support the lower mold component 222 and keep it stable. At this time, the first auxiliary component 41 located in the first space 1101 moves downward and to the position of the upper mold component 221, clamping the upper mold component 221 and driving it upward. At the same time, the lower mold component 222 also moves downward under the action of the second auxiliary component 42, so that the upper mold component 221 and the lower mold component 222 separate, thereby automatically removing the shoe from the upper mold component 221 and the lower mold component 222. This greatly reduces the force on the shoe during demolding, improves the stability of the structure, prevents damage to the shoe during demolding, reduces the tedious steps and instability of manual demolding, and improves the flow and accuracy of the demolding process by using the first auxiliary component 41 and the second auxiliary component 42 to demold the shoe, greatly reducing demolding errors, thereby reducing the scrap rate of the shoe and enhancing work efficiency.

[0135] Optionally, in some embodiments, please refer to Figure 1 The first auxiliary component 41 includes a first power unit 411, a first telescopic part 412, and a first auxiliary part 413. The first power unit 411 is disposed on the inner top wall of the housing 10. One end of the first telescopic part 412 is connected to the power output end of the first power unit 411. The first auxiliary part 413 is connected to the other end of the first telescopic part 412. The first auxiliary part 413 faces the second half mold 212. In the first retracted state, the first telescopic part 412 is used to drive the first auxiliary part 413 downward to the position of the upper mold 221, so that the first auxiliary part 413 can clamp the upper mold 221.

[0136] It is understood that the first power unit 411 can be a component capable of driving the first telescopic part 412 to extend and retract vertically. The telescopic part can be a component capable of driving the first auxiliary part 413 to extend downward and move upward. For example, the first power unit 411 may include a telescopic motor and a moving rod (rod-shaped structure), with the moving rod connected to the power output end of the telescopic motor, and the telescopic motor driving the moving rod to move, etc., but not limited to this. The first auxiliary part 413 can be a component capable of clamping the upper mold 221, and can be an automatic clamp, gripper, or clamp, etc. It can include a clamping execution component and a clamping drive component for driving the clamping execution component to clamp or release the upper mold 221. For example, the clamping execution component may include two clamping parts (which may be rod-shaped or plate-shaped structures) that are arranged opposite to each other and can be opened and closed relative to each other. The clamping drive component drives the two clamping parts to move closer to each other to clamp the upper mold 221 or to open relative to each other to release the upper mold 221. The clamping drive component may include a cylinder, a motor, etc., but not limited to this.

[0137] With this configuration, when the first movable rod 3112 switches from the first working state to the first retracted state, the first movable rod 3112 drives the second half mold 212 to move, and the second half mold 212 moves upward away from the first half mold 211 until it is parallel to the side wall of the housing 10; when the second movable rod 3122 switches from the second working state to the second retracted state, the second movable rod 3122 drives the first half mold 211 to move, and the first half mold 211 moves downward away from the second half mold 212 until it is parallel to the side wall of the housing 10; at this time, the molding inner mold 22 is exposed, and after the fasteners 223 are loosened to equal to the preset value, the second auxiliary component 42 located in the second space 1102 moves upward and moves to the position of the lower mold component 222, so that the second auxiliary component 42 contacts the lower mold component 222 to support the lower mold component 222 to keep it stable, and the first power unit 411 located in the first space 1101 drives the first telescopic part 412 to move downward. 412 drives the first auxiliary part 413 to move. The first auxiliary part 413 moves to the position of the upper mold 221, so that the first auxiliary part 413 contacts the upper mold 221. The first auxiliary part 413 will clamp the two side walls of the upper mold 221 in the width direction to clamp the upper mold 221. After clamping, the second auxiliary part 42 supports the lower mold 222, and the lower mold 222 remains stable. At this time, the upper mold 221 is clamped by the first auxiliary part 413 and moves upward. The lower mold 222 moves downward under the drive of the second auxiliary part 42, thereby automatically separating the shoe from the molding inner mold 22. This greatly reduces the force on the shoe during demolding, makes it convenient and quick to demold the shoe, protects the shoe from damage by force, reduces the possibility of defects on the surface of the shoe, improves the aesthetics of the shoe, enhances the structural stability of the shoe, prevents damage to the shoe during demolding, improves demolding accuracy, and increases demolding speed and demolding qualification rate.

[0138] Optionally, in some embodiments, please refer to Figure 1 The second auxiliary component 42 includes a second power unit 421, a second telescopic part 422, and a second auxiliary part 423. The second power unit 421 is disposed on the inner bottom wall of the housing 10. One end of the second telescopic part 422 is connected to the power output end of the second power unit 421. The second auxiliary part 423 is connected to the other end of the second telescopic part 422. The second auxiliary part 423 faces the first half-mold 211. In the second retracted state, the second telescopic part 422 is used to drive the second auxiliary part 423 upward to the position of the lower mold part 222, so that the second auxiliary part 423 can support the upper mold part 221.

[0139] It is understood that the second power unit 421 can be a component capable of driving the second telescopic part 422 to extend and retract vertically. The second telescopic part 422 can be a component capable of driving the second auxiliary part 423 to extend upward and retract downward. For example, the second power unit 421 can be a telescopic motor, and the second telescopic rod can be a rod-shaped structure connected to the telescopic shaft of the telescopic motor, etc., but is not limited to this. The second auxiliary part 423 can be a component capable of supporting the lower mold 222, for example, it can be a plate-shaped structure, etc., but is not limited to this. The shape of the second auxiliary part 423 can be a shape that matches the lower mold 222, etc., but is not limited to this.

[0140] With this configuration, when the first movable rod 3112 switches from the first working state to the first retracted state, the first movable rod 3112 drives the second half mold 212 to move, and the second half mold 212 moves upward away from the first half mold 211 until it is parallel to the side wall of the housing 10; when the second movable rod 3122 switches from the second working state to the second retracted state, the second movable rod 3122 drives the first half mold 211 to move, and the first half mold 211 moves downward away from the second half mold 212 until it is parallel to the side wall of the housing 10. At this time, the inner mold 22 is exposed. After the fasteners 223 are loosened to the preset value, the second power unit 421 in the second space 1102 drives the telescopic part to move upward. The second telescopic part 422 drives the second auxiliary part 423 to move upward as well, and moves the second auxiliary part 423 to the position of the lower mold 222, so that the second auxiliary part 423 contacts the lower mold 222 to support the lower mold 222 and keep it stable. The first power unit 411 in the first space 1101 moves downward. The first telescopic part 412 drives the first auxiliary part 413 to move downwards and to the position of the upper mold 221, so that the first auxiliary part 413 contacts the upper mold 221. The first auxiliary part 413 will clamp the two side walls of the upper mold 221 to clamp the upper mold 221. At this time, the first power part 411 drives the first telescopic part 412 to move upwards, the first auxiliary part 413 drives the upper mold 221 to move upwards, and the second power part 421 drives the second telescopic part 422 to move downwards. The second telescopic part 422 drives the second auxiliary part 423 to move downward. The lower mold part 222 moves downward under the drive of the second auxiliary part 423, thereby automatically separating the shoe from the molding inner mold 22. With the support of the second auxiliary part 423, the force on the lower mold part 222 when it is removed is reduced, so as to protect the shoe from damage. As a result, the surface of the shoe is smooth and flawless, thereby improving the aesthetics of the shoe, enhancing the structural stability of the shoe, increasing the demolding speed and demolding qualification rate, and further enhancing work efficiency.

[0141] Please refer to the following: Figures 1 to 6This application also provides a shoe forming method, using the shoe forming apparatus 100 of any of the above embodiments. The shoe forming method includes:

[0142] When the shoe is demolded, the shoe demolding device 30 inside the housing 10 first rotates the inner mold 22 in the accommodating space. The inner mold 22 drives the vent 22201 on the lower mold 222 to rotate, so that the vent 22201 is connected to the air extraction hole 21101 on the first half mold 211, and the gas in the inner mold 22 is discharged.

[0143] After the first half mold 211 and the second half mold 212 are separated by the shoe demolding device 30, the upper mold 221 and the lower mold 222 are opened by the auxiliary device 40 to remove the shoe from the shoe cavity.

[0144] With this configuration, when the molded shoe needs to be demolded, the upper mold 221 and the lower mold 222 interlock, forming a mounting part 224 by the upper connecting part 2211 of the upper mold 221 and the lower connecting part 2221 of the lower mold 222. The adjusting shaft 332 is then mounted onto the mounting part 224. One end of the adjusting shaft 332 is connected to the power output shaft of the power component 331. The power component 331 then rotates the adjusting shaft 332 according to a preset value and direction. Since the other end of the adjusting shaft 332 is connected to the mounting part 224, the mounting part 224 is also rotated. At this time, the upper mold 221 and the lower mold 222 rotate within the accommodating space. The rotation of the lower mold 222 causes the vent 22201 to rotate. The hole 22201 is rotated to the air extraction hole 21101, so that the exhaust hole 22201 is connected to the air extraction hole 21101. At this time, the air extraction branch pipe 323 is connected to the exhaust hole 22201. Since one end of the connector 322 is connected to the air extraction machine 321 and one end of the air extraction branch pipe 323 is connected to the other end of the connector 322, the air extraction machine 321 is connected to the air extraction branch pipe 323 through the connector 322. When the air extraction branch pipe 323 is working, the air extraction machine 321 extracts the gas in the molding inner mold 22. The gas in the molding inner mold 22 is extracted from the exhaust hole 22201 of the lower mold part 222, and then through the air extraction hole 21101 of the first half mold 211 to the air extraction branch pipe 323, and then input into the air extraction machine 321 through the connector 322, thereby extracting the gas in the molding inner mold 22.

[0145] Once gas extraction is complete, the first movable rod 3112 needs to be switched from the first working state to the first retracted state. At this time, the first fixed rod 3111 drives the first movable rod 3112 to rotate upwards, and the first movable rod 3112 drives the second half-mold 212 to move upwards, moving it away from the first half-mold 211 until it is parallel to the side wall of the housing 10. Additionally, the second movable rod 3122 needs to be switched from the second working state to the second retracted state. The second fixed rod 3121 drives the second movable rod 3122 to rotate downwards, and the second movable rod 3122 drives the first half-mold 211 to move. Therefore, the second half-mold 212... The first half mold 211 moves downwards until it is parallel to the side wall of the housing 10; the first half mold 211 is in the first retracted state and the second half mold 212 is in the second retracted state. Under the action of the first processing component 311 and the second processing component 312, the first half mold 211 and the second half mold 212 can be opened conveniently and quickly. Then, the fasteners 223 on each of the first fastening holes and each of the second fastening holes are loosened. The multiple fasteners 223 are connected to the multiple first fastening holes and the multiple second fastening holes in a one-to-one correspondence. Therefore, the fasteners 223 on both sides away from the middle fastener 223 are loosened diagonally first, and then the middle fastener 223 is loosened.

[0146] When the fasteners 223 on each of the first and second fastening holes are loosened, the second power unit 421 located in the second space 1102 drives the telescopic part to move upward. The second telescopic part 422 drives the second auxiliary part 423 to move upward as well, and moves the second auxiliary part 423 to the position of the lower mold 222, so that the second auxiliary part 423 contacts the lower mold 222 to support the lower mold 222 and keep it stable. The first power unit 411 located in the first space 1101 moves downward. The first telescopic part 412 drives the first auxiliary part 413 to move downward and moves the first auxiliary part 413 to the position of the upper mold 221, so that the first auxiliary part 413 contacts the upper mold 221. The first auxiliary part 413 will clamp the two side walls of the upper mold 221 to clamp the upper mold 221. At this time, the first power unit 411 drives the second auxiliary part 423 to move upward. A telescopic part 412 moves upward, a first auxiliary part 413 drives the upper mold 221 to move upward, a second power part 421 drives the second telescopic part 422 to move downward, the second telescopic part 422 drives the second auxiliary part 423 to move downward, and the lower mold 222 moves downward under the drive of the second auxiliary part 423, thereby automatically separating the shoe from the molding inner mold 22. This allows the shoe to be demolded quickly and easily, preventing gas from entering the shoe cavity in the molding inner mold 22 and causing defects on the shoe surface. This improves the surface quality and structural stability of the shoe, makes the force more uniform during demolding, reduces excessive or uneven force, increases the pass rate of the shoe, reduces resource waste, and further improves the demolding speed and smoothness of the shoe, thus improving the quality and work efficiency of the shoe.

[0147] As can be seen from the above, when the shoe mold 20 provided in this application needs to be demolded, the shoe demolding device 30 drives the inner mold 22 in the first space 1101 to rotate within the accommodating space; when the lower mold 222 rotates, it can drive the vent 22201 to rotate, and the lower mold 222 drives the vent 22201 to rotate to the air extraction hole 21101, so that the vent 22201 and the air extraction hole 21101 are connected, which can facilitate the gas in the shoe cavity to be discharged through the vent 22201, enhance the structural uniformity of the shoe after demolding, and reduce the defects on the surface of the shoe caused by the gas generated in the shoe cavity; when the vent 22201 rotates, it can drive ... inner mold 22201 to rotate, and drive the inner mold 22201 to rotate to the air extraction hole 21101, so that the gas in the shoe cavity can be discharged through the vent 22201, enhance the structural uniformity of the shoe after demolding, and reduce the defects on the surface of the shoe caused by the gas generated in the shoe cavity; when the vent 22201 rotates, it can drive the inner mold 22201 to rotate, and drive the inner mold 22201 to rotate, and drive the inner mold 22201 to rotate, and drive the inner mold 22201 to rotate, and drive the inner mold 22201 to After the venting is completed at hole 22201, the first half mold 211 and the second half mold 212 are opened by the shoe demolding device 30. Finally, the upper mold 221 and the lower mold 222 are separated by the auxiliary device 40 to remove the molded shoe. The first half mold 211 and the second half mold 212 can protect the upper mold 221 and the lower mold 222 to maintain stability, thereby reducing the possibility of damage to the shoe due to structural instability. The separation of the upper mold 221 and the lower mold 222 by the auxiliary device 40 improves the uniform force during demolding, thereby improving the surface of the demolded shoe without defects, further improving the pass rate of the shoe and improving work efficiency.

[0148] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
