Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a 3D molding machine capable of automatic mold changing. Background Technology

[0002] With the rapid development of modern manufacturing, 3D molding technology has been widely used in industrial production. Existing 3D molding machines, as important manufacturing equipment, play a crucial role in various fields such as automobiles, aerospace, medical devices, and electronic products. However, under current technological levels, mold changing for 3D molding machines still mainly relies on manual operation, a traditional method that presents significant technical bottlenecks and practical problems.

[0003] In existing technologies, when it is necessary to change molding dies of different specifications or shapes, operators must stop the machine and manually complete the entire replacement process. This process typically includes: first, disconnecting the power supply to ensure safety; then, using specialized tools to remove the fixing bolts and carefully removing the old mold; next, installing the new mold and adjusting its position; and finally, retightening the connecting parts and restoring the equipment to operation. The entire replacement process often takes several hours or even longer, which not only consumes a lot of manpower but also seriously affects production efficiency.

[0004] In addition, manual mold changing has many other problems: operators need to have professional skills and experience, resulting in high training costs; manual operation is prone to installation errors, affecting product quality; frequent disassembly and assembly operations increase the risk of equipment wear and safety accidents; at the same time, the complex replacement process also limits the flexibility of the production line, making it difficult to adapt to the modern production needs of small batches and multiple varieties.

[0005] Therefore, there is an urgent need for 3D molding machines that can automatically change molds to solve the above problems. Summary of the Invention

[0055] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0056] like Figures 1 to 10As shown, this embodiment provides a 3D molding machine capable of automatic mold changing. This machine includes a mold tray 1, a mold positioning platform 2, a storage container 3, and a transfer mechanism 4. The mold tray 1 is used to set the mold 100. The mold positioning platform 2 includes a first positioning component 21 and a second positioning component 22 spaced apart along a first horizontal direction X. The first positioning component 21 and the second positioning component 22 can respectively support both sides of the mold tray 1 along the first horizontal direction X. The storage container 3 and the mold positioning platform 2 are arranged along a second horizontal direction Y. The storage container 3 includes a lifting mechanism 32 and a transfer mechanism 4. Two support frames 31 are spaced apart in the first horizontal direction X. The two support frames 31 can support the mold pallet 1 on both sides along the first horizontal direction X respectively. The lifting mechanism 32 is used to drive the two support frames 31 to lift synchronously. The transfer mechanism 4 includes a drive assembly 41 and a fork 42. The drive assembly 41 drives the fork 42 to move along the second horizontal direction Y so that the fork 42 can move between the first positioning assembly 21 and the second positioning assembly 22 and between the two support frames 31. The drive assembly 41 can also drive the fork 42 to move along the vertical direction Z. The first horizontal direction X and the second horizontal direction Y are perpendicular. Initially, the mold pallet 1 carrying the mold 100 is placed in the storage warehouse 3. When it is necessary to move the mold 100 to the mold positioning platform 2, the drive assembly 41 drives the fork 42 to move along the second horizontal direction Y to below the two support frames 31. At this time, the lifting mechanism 32 drives the two support frames 31 to move synchronously along the vertical direction Z towards the ground, thereby causing the fork 42 to lift the mold pallet 1 from the two support frames 31. Subsequently, the drive assembly 41 can drive the fork 42 to move along the second horizontal direction Y to above the mold positioning platform 2. The drive assembly 41 drives the fork 42 to move along the vertical direction Z towards the ground, thereby enabling the first positioning assembly 21 and the second positioning assembly 22 to support the mold pallet 1 on both sides along the first horizontal direction X, thereby realizing the transfer of the mold 100 from the storage warehouse 3 to the mold positioning platform 2. Similarly, the transfer mechanism 4 can also transfer the mold 100 on the mold positioning platform 2 to the storage warehouse 3. This 3D molding machine with automatic mold changing capability achieves fully automatic mold changing, which not only reduces labor costs and improves work efficiency, but also improves installation accuracy and product quality.

[0057] Optionally, the 3D molding machine capable of automatic mold changing also includes a 3D pressing mechanism 5. The 3D pressing mechanism 5 is arranged vertically Z above the mold positioning platform 2, thereby actuating the mold 100 on the mold tray 1. The actuation of the mold 100 by the 3D pressing mechanism 5 is prior art and will not be described in detail here.

[0058] Optionally, the support frame 31 includes a connecting plate 311 and a plurality of support plates 312 spaced apart along the vertical direction Z on the connecting plate 311. The plurality of support plates 312 on one support frame 31 correspond one-to-one with the plurality of support plates 312 on another support frame 31. One support plate 312 on one support frame 31 and the corresponding support plate 312 on the other support frame 31 are used to support the mold tray 1 on both sides along the first horizontal direction X, respectively. In this embodiment, on the two support frames 31, each pair of opposite support plates 312 forms a placement position, thereby forming multiple placement positions along the vertical direction. Each placement position can be equipped with a mold tray 1, so that a storage warehouse 3 can hold multiple molds 100 of different models. The height of the two support frames is adjusted by the lifting mechanism 32, thereby allowing the forks 42 to move below different placement positions in the storage warehouse 3.

[0059] Optionally, the lifting mechanism 32 includes two slide rails 321, two lead screws 322, two nuts 323, and a drive assembly 41. The two support frames 31, two slide rails 321, two lead screws 322, and two nuts 323 correspond one-to-one. The slide rails 321 are spaced apart along the first horizontal direction X and extend along the vertical direction Z. The connecting plate 311 slides in cooperation with the corresponding slide rail 321. The lead screws 322 extend along the vertical direction Z. The nuts 323 are screwed to the corresponding lead screws 322 and connected to the corresponding connecting plate 311. The power assembly 324 is used to drive the two lead screws 322 to rotate synchronously. In this embodiment, each of the two connecting plates 311 is provided with a sliding groove, and the slide rail 321 slides in the corresponding sliding groove, thereby enabling the two support frames 31 to slide on the corresponding two slide rails 321. The two connecting plates 311 are respectively connected to two nuts 323. When the drive assembly 41 drives the two lead screws 322 to rotate synchronously and in the same direction, the two nuts 323 move synchronously on the two lead screws 322, thereby driving the two support frames 31 to slide synchronously on the corresponding two slide rails 321.

[0060] Optionally, the power assembly 324 includes a motor 3241, a coupling 3242, and two commutators 3243. The first output shafts of the two commutators 3243 are respectively connected to two lead screws 322. The two ends of the coupling 3242 are respectively connected to the second output shaft of one commutator 3243 and the input shaft of the other commutator 3243. The motor 3241 is connected to the input shaft of one commutator 3243. In this embodiment, the motor 3241 transmits power to one commutator 3243. The commutator 3243 connected to the motor 3241 transmits the power of the motor 3241 to one lead screw 322 and the coupling 3242 respectively. The coupling 3242 transmits the received power to the other commutator 3243, thereby driving the other lead screw 322 so that the two lead screws 322 can rotate synchronously. The commutator 3243 is used to change the direction of power transmission, and the coupling 3242 is used to connect the two commutators 3243 in a transmission connection.

[0061] Optionally, the lifting mechanism 32 also includes two leveling components 325, and the two support frames 31, two nuts 323 and two leveling components 325 are arranged in a one-to-one correspondence; the leveling component 325 includes a connecting block 3251 and a lifting block 3252, the connecting block 3251 is connected to the corresponding nut 323, the connecting block 3251 and the lifting block 3252 are detachably connected, and the lifting block 3252 is fixedly connected to the corresponding support frame 31. In this embodiment, during the assembly of the lifting mechanism 32, due to manufacturing and assembly errors of various components, the two nuts 323 may not be at the same height along the vertical direction Z. To solve this problem, the connecting block 3251 and the lifting block 3252 corresponding to any one nut 323 can be disconnected. Then, the nut 323 is rotated so that it and the other nut 323 are at the same height along the vertical direction Z. The connecting block 3251 and the lifting block 3252 corresponding to the nut 323 are then reconnected, thus completing the adjustment of the error of the two nuts 323 along the height direction.

[0062] Optionally, the leveling assembly 325 further includes a floating block 3253 and a limiting shell. The limiting shell is detachably disposed on the lifting block 3252 and forms a limiting groove with the lifting block 3252. The floating block 3253 is disposed in the limiting groove and can move in the limiting groove along the first horizontal direction X and the second horizontal direction Y. The limiting shell restricts the floating block 3253 from rotating around the axis of the lead screw 322. The connecting block 3251 is detachably connected to the floating block 3253. In this embodiment, due to the horizontal error between the slide rail 321 and the support frame 31 and the position error of the lead screw 322, this setting can effectively improve the problem of the lifting mechanism 32 being unable to be installed and difficult to install. Specifically, the limiting shell includes two L-shaped plates, each L-shaped plate including a first plate 3254 and a second plate 3255. The two first plates 3254 are spaced apart from the lifting block 3252 along the second horizontal direction Y, and the two second plates 3255 are spaced apart from the lifting block 3252 along the vertical direction Z. The floating block 3253 is located between the two first plates 3254 and between the second plate 3255 and the lifting block 3252. The floating block 3253 has protruding locking protrusions 3257 on both sides along the second horizontal direction Y. Both first plates 3254 are provided with locking holes 3256. The locking protrusions 3257 are inserted into the corresponding locking holes 3256. The two first plates 3254 are in clearance fit with the floating block 3253. The locking protrusions 3257 are in clearance fit with the inner wall of the corresponding locking hole 3256 along the first horizontal direction X. This allows the floating block 3253 to adjust its position relative to the lifting block 3252 along the first horizontal direction X and the second horizontal direction Y, but it cannot rotate around the axis of the lead screw 322, which facilitates the installation of the lifting mechanism 32.

[0063] Optionally, the first positioning component 21 includes a first positioning plate 211 with a first limiting groove 2111; the second positioning component 22 includes a second positioning plate 221 with the first limiting groove 2111; the support plate 312 has a second limiting groove 3121; the mold tray 1 has a limiting protrusion 11; when the first positioning plate 211 and the second positioning plate 221 support the mold tray 1 along both sides of the first horizontal direction X, the limiting protrusion 11 is inserted into the first limiting groove 2111 in a one-to-one correspondence; when the two corresponding support plates 312 on the two support frames 31 support the mold tray 1 along both sides of the first horizontal direction X, the limiting protrusion 11 is inserted into the second limiting groove 3121 on the corresponding two support plates 312 in a one-to-one correspondence. In this embodiment, this arrangement can achieve the initial positioning of the mold tray 1 on the first positioning plate 211 and the second positioning plate 221, and similarly, it can achieve the initial positioning of the mold tray 1 on the two corresponding support plates 312.

[0064] Optionally, the first positioning plate 211 is provided with two first guide blocks 2112 at intervals along the second horizontal direction Y, and the second positioning plate 221 is provided with two first guide blocks 2112 at intervals along the second horizontal direction Y; the support plate 312 is provided with two second guide blocks 3122 at intervals along the second horizontal direction Y; when the first positioning plate 211 and the second positioning plate 221 support the mold tray 1 on both sides along the first horizontal direction X, the two first guide blocks 2112 on the first positioning plate 211 are located on both sides of the mold tray 1 along the second horizontal direction Y, and the two first guide blocks 2112 on the second positioning plate 221 are located on both sides of the mold tray 1 along the second horizontal direction Y; when the two corresponding support plates 312 on the two support frames 31 support the mold tray 1 on both sides along the first horizontal direction X, the two second guide blocks 3122 on the support plate 312 are located on both sides of the mold tray 1 along the second horizontal direction Y. In this embodiment, the surface of the first guide block 2112 opposite to the mold tray 1 is inclined, which can guide the mold tray 1 and facilitate the insertion of the limiting protrusion 11 of the mold tray 1 into the corresponding first limiting groove 2111; the surface of the second guide block 3122 opposite to the mold tray 1 is inclined, which can guide the mold tray 1 and facilitate the insertion of the limiting protrusion 11 of the mold tray 1 into the corresponding second limiting groove 3121.

[0065] In this embodiment, two follower bearings are provided on each of the two side walls of the mold tray 1 along the second horizontal direction Y. During the process of placing the mold tray 1 on the first positioning plate 211 and the second positioning plate 221, the four follower bearings abut against the four first guide blocks 2112 respectively. During the process of placing the mold tray 1 on the corresponding two support plates 312, the four follower bearings abut against the four second guide blocks 3122 respectively.

[0066] Optionally, the mold tray 1 has a positioning groove 12 recessed on one side wall along the first horizontal direction X; the first positioning assembly 21 also includes a first limiting member 212, which is disposed on the first positioning plate 211 and is opposite to the positioning groove 12 along the first horizontal direction X. The limiting pin 2121 of the first limiting member 212 can extend into the positioning groove 12 along the first horizontal direction X, and the limiting pin 2121 abuts against the two side walls of the positioning groove 12 along the second horizontal direction Y. In this embodiment, the first limiting member 212 is a telescopic cylinder. The telescopic part of the telescopic cylinder is fixedly connected to the limiting pin 2121 and drives the limiting pin 2121 to move along the first horizontal direction X, thereby causing the limiting pin 2121 to be inserted into the positioning groove 12. Since the limiting pin 2121 abuts against the two side walls of the positioning groove 12 along the second horizontal direction Y, the mold tray 1 is limited along the second horizontal direction Y.
