[0002] 3D printed shoes refer to personalized shoes made through high-precision 3D printing technology. Unlike traditional shoemaking techniques, 3D printing technology can directly transform digital designs into physical products without the need for molds or complex production processes. This means that designers can give full play to their creativity and create shoes of various shapes and functions to meet the personalized needs of consumers.

[0004] Nowadays, shoe manufacturers commonly use various molds and tools for injection molding, extrusion, die-casting and other methods to obtain the required products. When shoes need to be manufactured, the material is first injected into the mold, and then the mold cover is covered and the mold is closed. The material quickly fills every corner of the mold under high temperature and high pressure. However, the existing molds are usually exposed to the external environment, which leads to a series of problems. First, the mold is exposed to the air for a long time and is easily corroded by pollutants such as dust and water vapor, which in turn affects the production quality of the shoes. The accumulation of dust will not only increase the difficulty of cleaning the mold, but may also mix into the material during the injection molding process, resulting in defects on the surface of the shoe. In addition, the mold cover may not be sealed enough, and the intrusion of water vapor may cause rust inside the mold, reducing the durability and precision of the mold. Summary of the invention

[0023] 1. The present application solves the problem that the mold is exposed to the air for a long time and is easily corroded by pollutants such as dust and water vapor, thereby affecting the production quality of shoes by providing a chassis mechanism, a chassis, a mold outer box, and a top plate mechanism. The accumulation of dust will not only increase the difficulty of cleaning the mold, but may also mix into the material during the injection molding process, resulting in defects on the surface of the shoe. Specifically, when making shoes, the motor is started, and the irregular toothed disc is driven to rotate through the transmission device, and then the mold box connecting disc is driven to rotate, so that the mold outer box body is aligned with the rectangular groove of the top plate.

The nozzle device has been installed on the fixed block, and the material is extracted through the feed pipe and injected into the inner wall of the mold box. BRIEF DESCRIPTION OF THE DRAWINGS

A push-pull plate 1114 is rotatably connected to the right side of the second rotating rod 1113 away from the hinged rod 1112. Push rods 1115 are fixedly connected to the front and rear sides of the inner wall of the push-pull plate 1114 respectively. The outer wall bottoms of the two push rods 1115 are slidably connected to the front and rear sides of the inner wall of the sliding rod connecting plate 1119 respectively. The mold outer box 12 includes a mold outer box main body 121, and push rod grooves 122 are respectively provided on both sides of the bottom of the inner wall of the mold outer box main body 121. The inner wall of the mold outer box main body 121 slides A mold box 123 is connected, and a mold cover 124 is movably connected to the top of the mold box 123.

A top plate rectangular groove 22 is opened on the left side of the top of the top plate body 21. A motor bottom plate 25 is fixedly connected to the right side of the top of the top plate body 21. The inner sides of the two connecting rods 23 on the right are fixedly connected with connecting cross bars 24. The inner sides of the two connecting cross bars 24 are fixedly connected to the front and rear sides of the left connecting block 117. The top of the motor bottom plate 25 is fixedly connected with a motor 26.The output end of the motor 26 is fixedly connected to a transmission disc 27, the outer wall of the transmission disc 27 is covered with a crawler 28, and the inner wall of the crawler 28 away from the transmission disc 27 is covered with a second transmission disc 29, and the left side of the second transmission disc 29 is fixedly connected to the right end of the transmission disc connecting rod 1118;

[0039] When it is necessary to make shoes, the motor 26 is first started. The rotation of the motor 26 drives the crawler belt 28 to rotate through the transmission disc 27, and then drives the second transmission disc 29 to rotate. Since the second transmission disc 29 is fixedly connected to the transmission disc connecting rod 1118, this rotation action drives the transmission disc connecting rod 1118 and the irregular toothed disc 118 connected thereto to rotate together;

[0040] The rotation of the irregular toothed disc 118 makes the tooth block on the front side of its outer wall mesh with the irregular gear 119. Due to the design of the irregular gear 119, when the non-tooth block surface of the irregular toothed disc 118 fits with the arc groove surface of the irregular gear 119, the rotating rod 1110 stops rotating. When the irregular toothed disc 118 continues to rotate, the irregular toothed disc 118 presses the push rod 1117 by rotating the pressing rod 1116, so that the push rod 1117 drives the irregular gear 119 to continue rotating and the irregular gear 119 meshes with the tooth block surface of the irregular toothed disc 118 again.

[0041] The rotation of the irregular toothed disc 118 drives the rotating rod 1120 to rotate, and the rotating rod 1120 drives the second conical teeth 116 to rotate and engage the conical teeth 115 to drive the mold box connecting disc rotating rod 112 to rotate, so that the mold box connecting disc 113 at the top of the mold box connecting disc rotating rod 112 rotates, and the mold box connecting disc 113 rotates to drive the mold outer box body 121 fixed to the inner wall of the mold box connecting groove 114 to rotate and align with the top plate rectangular groove 22 opened on the top of the top plate body 21;

[0042] At the same time, when the irregular toothed disc 118 is meshed with the irregular gear 119, the irregular gear 119 rotates to drive the rotating rod 1110, and the rotating rod 1110 rotates to drive the rotating rod 1111 to rotate and pull the second rotating rod 1113 to rotate through the hinge rod 1112, and the second rotating rod 1113 rotates downward, thereby pushing the push-pull plate 1114 to drive the two push rods 1115 on the inner wall to move upward, and the two push rods 1115 on the inner wall of the push-pull plate 1114 move upward, thereby passing through the two push rod grooves 122 opened at the bottom of the mold outer box body 121, and pushing the mold box 123 upward on the inner wall of the mold outer box body 121 to push the mold box 123 to the top outer wall of the top plate body 21. At this time, the mold cover 124 on the top of the mold box 123 is opened and the material is injected The material is then covered with the mold cover 124, and then the motor 26 is restarted, and the whole system enters the next working cycle. At this time, the continuous rotation of the motor 26 continues to drive the meshing movement between the irregular toothed disc 118 and the irregular gear 119 through the transmission device, and the mold outer box body 121 is pulled to the bottom of the mold box connecting disc 113 through the mold box connecting disc 113, and at the same time, the mold box connecting disc rotating rod 112 continues to rotate the mold outer box body 121 on the inner wall of the mold box connecting groove 114 on the other side to the top plate rectangular groove 22 opened on its top plate body 21. This design cleverly utilizes the characteristics of irregular tooth shape, realizes intermittent power transmission and conversion, and ensures that the mold box 123 injects and solidifies the material at the correct time and position.

[0043] See also Fig. 9 The material injection mechanism 3 includes a material box 31, a transmission column 32 is fixedly connected to the left side of the material box 31, the material box 31 and the bottom of the transmission column 32 are fixedly connected to the top of the top plate body 21, the front and rear sides of the left side of the transmission column 32 are respectively fixedly connected to the sliding rod 33, the left side of the front side of the transmission column 32 is fixedly connected to the rack rod 34, the left side of the transmission column 32 is slidably connected to the nozzle fixing block 35, the front and rear sides of the right side of the nozzle fixing block 35 are respectively fixedly connected to the fixing block slide plate 36, the inner sides of the two fixing block slide plates 36 are respectively slidably connected to the two sliding rods 33 On the outside, the front side of the front fixed block slide plate 36 is fixedly connected to a gear motor connecting plate 37, the right side of the gear motor connecting plate 37 is fixedly connected to an L-shaped motor placement plate 38, the front side of the L-shaped motor placement plate 38 is fixedly connected to a gear motor 39, the output end of the gear motor 39 extends to the rear side of the L-shaped motor placement plate 38 and is fixedly connected to a gear 310, the outer wall of the gear 310 engages one side of the rack rod 34, the top of the nozzle fixing block 35 is fixedly connected to a material passing pipe 311, and the side of the material passing pipe 311 away from the nozzle fixing block 35 is fixedly connected to the top of the material box 31;

[0044] When it is necessary to inject material, the gear motor 39 is first started. As the output end of the gear motor 39 rotates, the gear 310 begins to mesh with the rack rod 34. This design cleverly utilizes the transmission principle of the gear and the rack to convert the rotational motion of the motor into linear motion. As the gear 310 gradually moves on the rack rod 34, the L-shaped motor placement plate 38 fixedly connected to the gear motor 310 and the gear motor connection plate 37 in front also move accordingly.

[0045] Since the fixed block slide plates 36 are respectively slidably connected to the outer sides of the slide rods 33, this structural design ensures the stability and accuracy of the nozzle fixed block 35 during horizontal movement. As the nozzle fixed block 35 slides smoothly on the left side of the transmission column 32, the feed pipe 311 connected to the top of it also moves synchronously, and the nozzle fixed block 35 is close to the mold box 123 on the surface of the top plate main body 21. At this time, the corresponding nozzle device has been installed on the nozzle fixed block 35, and the material on the inner wall of the material box 31 is extracted through the feed pipe 311 and injected into the inner wall of the mold box 123 through the nozzle device installed on the nozzle fixed block 35.

[0046] In addition, the present invention also relates to a manufacturing mold and a manufacturing method of shoes based on 3D printing, comprising the following steps:

[0047] Step 1: First, place the mold box 123 on the inner wall of the mold outer box body 121 and ensure that the mold box 123 and the mold outer box body 121 are accurately positioned without deviation or tilt, and then tightly close the mold cover 124 on the top of the mold box 123;

[0048] Step 2: Start the motor 26, which drives the meshing movement of the irregular toothed disc 118 and the irregular gear 119 through the transmission device. As the irregular toothed disc 118 rotates, the mold box connecting disc 113 rotates the mold box connecting disc rotating rod 112 to accurately align the mold outer box body 121 and the internal mold box 123 to the top plate rectangular groove 22 of the top plate body 21. In this step, the characteristics of the irregular tooth shape ensure the intermittent and accurate power transmission, so that the mold box can accurately reach the specified position;

[0049] Step three: After the mold box 123 is aligned with the rectangular groove 22 of the top plate, the material injection mechanism 3 starts to work, and the gear motor 39 starts. Through the meshing movement of the gear 310 and the rack rod 34, the nozzle fixing block 35 is smoothly moved to the top of the mold box 123. At this time, the nozzle device on the nozzle fixing block 35 starts to work, and the material in the material box 31 is extracted through the material pipe 311 and injected into the inner wall of the mold box 123. During the injection process, it is necessary to ensure the uniform distribution and sufficient amount of the material to ensure the quality and integrity of the product.

[0050] Step 4: After the material is injected, the mold cover 124 continues to remain tightly closed to allow the material to solidify in the mold box 123. The solidification time depends on the characteristics and requirements of the material. It is necessary to ensure that the material is fully solidified to form a stable product structure.

[0051] Working principle: when it is necessary to make shoes, the motor 26 is first started. The rotation of the motor 26 drives the crawler belt 28 to rotate through the transmission disc 27, and then drives the second transmission disc 29 to rotate. Since the second transmission disc 29 is fixedly connected to the transmission disc connecting rod 1118, this rotation action will drive the transmission disc connecting rod 1118 and the irregular toothed disc 118 connected thereto to rotate together. Since the rotation of the irregular toothed disc 118 drives the rotating rod 1120 to rotate, the rotating rod 1120 drives the second conical teeth 116 to rotate and engage the conical teeth 115 to drive the mold box connecting disc rotating rod 112 to rotate, so that the mold The mold box connecting plate 113 at the top of the tool box connecting plate rotating rod 112 rotates, and the mold box connecting plate 113 rotates to drive the mold outer box body 121 fixed to the inner wall of the mold box connecting groove 114 to rotate and align with the top plate rectangular groove 22 opened on the top of the top plate body 21. At the same time, when the irregular toothed plate 118 is engaged with the irregular gear 119, the irregular gear 119 rotates to drive the rotating rod 1110, and the rotating rod 1110 rotates to drive the rotating rod 1111 to rotate and pull the second rotating rod 1113 to rotate through the hinge rod 1112, and the second rotating rod 1113 moves downward. The two push rods 1115 on the inner wall of the push-pull plate 1114 move upward, and the two push rods 1115 on the inner wall of the push-pull plate 1114 move upward, so as to push the mold box 123 upward to the top outer wall of the top plate body 21 through the two push rod grooves 122 opened at the bottom of the mold outer box body 121. At this time, the mold cover 124 on the top of the mold box 123 is opened and the material is injected, and then the mold cover 124 is covered, and then the motor 26 is restarted, and the whole system enters the next working cycle. At this time, the continuous rotation of the motor 26 is transmitted through the transmission The device continues to drive the meshing movement between the irregular toothed disc 118 and the irregular gear 119, and pulls the mold outer box body 121 to the bottom of the mold box connecting disc 113 through the mold box connecting disc 113, and at the same time, the mold box connecting disc rotating rod 112 continues to rotate the mold outer box body 121 on the inner wall of the mold box connecting groove 114 on the other side to the top plate rectangular groove 22 opened on its top plate body 21. This design cleverly utilizes the characteristics of the irregular tooth shape to achieve intermittent power transmission and conversion, ensuring that the mold box 123 is injected and cured at the correct time and position;

[0052] When it is necessary to inject material, the gear motor 39 is first started. As its output end rotates, the gear 310 begins to mesh with the rack rod 34. This design cleverly utilizes the transmission principle of the gear and the rack to convert the rotational motion of the motor into a linear motion. As the gear 310 gradually moves on the rack rod 34, the L-shaped motor placement plate 38 fixedly connected thereto and the gear motor connecting plate 37 in front also move accordingly. Since the fixed block slide plate 36 is respectively slidably connected to the outer side of the slide rod 33, this structural design ensures the stability and accuracy of the nozzle fixing block 35 during the horizontal movement. As the nozzle fixing block 35 slides smoothly on the left side of the transmission column 32, the feed pipe 311 connected to the top of it also moves synchronously. The nozzle fixing block 35 is close to the mold box 123 on the surface of the top plate body 21. At this time, the corresponding nozzle device has been installed on the nozzle fixing block 35. The material on the inner wall of the material box 31 is extracted through the feed pipe 311 and injected into the inner wall of the mold box 123 through the nozzle device installed on the nozzle fixing block 35.
