Description

Technical Field

[0001] The present invention belongs to the technical field of 3D molding machines, and particularly relates to a 3D molding machine capable of automatically changing molds. Background Art

[0002] Hairpin permanent magnet synchronous motors (hairpin motors) are being gradually and widely applied in the domestic drive motor market. Compared with traditional wound motors, due to the flat characteristics of hairpin copper wires, at the same power, the motor has a smaller volume and higher power, which is the development direction of the next-generation new energy drive motors. During the copper wire forming process, 3D molding dies are required to shape the copper wires. Since there are more than a dozen wire types on the stator, different shapes need to be formed at the hairpin ends of the copper wires to meet the requirements of different wire type production.

[0003] Currently, a Chinese patent with the publication number CN218855482U discloses a 3D forming mechanism for hairpin motor flat copper wires, including a workbench. A forming part is arranged on the workbench, and the forming part can realize 3D forming of different wire types of copper wires. A wire transfer part is arranged on the workbench, and the wire transfer part can transfer the copper wire into the forming part. A wire fixing part located on the workbench is arranged on one side of the forming part for fixing the copper wire. When in use, different molds are installed on the forming part, and according to the position of the mold moving to the fixing part, different 3D forming structures can be switched and formed. After the switching is completed, the wire transfer part moves the copper wire into the forming part, and the first cylinder claw clamps and fixes the copper wire. The forming part performs 3D forming on the copper wire. After the 3D forming of the copper wire, the wire transfer part moves the formed copper wire out and then clamps and takes a new copper wire and puts it into the forming part. However, when this technical solution is used, all the molds will work, and after long-term use, the molds themselves may be damaged, thus affecting the service life of the molds. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a 3D molding machine capable of automatically changing molds.

[0005] The technical solution of the present invention is as follows:

Detailed Description of the Preferred Embodiment

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 7 shown, a 3D molding machine capable of automatically changing molds includes a support tooling and a mold tooling 5 slidably disposed within the support tooling. The support tooling can drive the mold tooling 5 to move up and down. A 3D molding assembly 3 is disposed on one side surface of the support tooling. A plurality of mold plates 38 are horizontally slidably disposed within the mold tooling 5. The 3D molding assembly 3 is provided with a positioning cylinder 36 capable of inserting into the mold plate 38, so that the mold plate 38 is limited and fixed within the 3D molding assembly 3.

[0030] An automatic mold changing assembly 6 is disposed on the side surface of the support tooling facing away from the 3D molding assembly 3. The automatic mold changing assembly 6 is provided with a clamping block 65. The mold plate opens a T-shaped through groove 30. The through groove 30 can be slidably inserted up and down onto the clamping block 65. The automatic mold changing assembly 6 can drive the mold plate 38 to slide into the 3D molding assembly 3 through the clamping block 65.

[0031] During use, copper wires are placed into the 3D molding assembly 3 for 3D extrusion molding. When the mold needs to be replaced, the output end of the positioning cylinder 36 retracts, and the mold plate 38 is no longer limited. The mold plate 38 in the 3D molding assembly 3 is taken out and slid into the mold tooling 5 through the automatic mold changing assembly 6. Then, the support tooling drives the mold tooling 5 to move up and down, so that the corresponding mold plate 38 is aligned with the 3D molding assembly 3. During the up and down movement of the mold tooling 5, the through groove 30 passes through the clamping block 65, and the through groove 30 is inserted into the clamping block 65 when the corresponding mold plate 38 is aligned with the 3D molding assembly 3. At this time, the automatic mold changing assembly 6 drives the mold plate 38 to move through the clamping block 65, so that the mold plate 38 moves into the 3D molding assembly 3. Then, the output shaft of the positioning cylinder 36 extends and inserts into the mold plate 38, and the mold plate 38 is limited and fixed within the 3D molding assembly 3. Then, 3D molding can be carried out according to the above process.

[0032] Among them, it should be noted that the mold is disposed on the mold plate 38, or the mold plate 38 can be directly replaced with the mold, where the mold includes an upper mold and a lower mold.

[0033] In this embodiment, the 3D molding assembly 3 includes a fixed shell and two mold sliders 37 slidably connected up and down between two vertical plates 32. Opposite side surfaces of the two mold sliders 37 are both provided with sliding grooves 33 for the mold plate 38 to slide.

[0034] Servo cylinders II 35 are fixed to both the upper and lower sides of the fixed housing. The servo cylinders II 35 are fixedly connected to the adjacent die sliders 37.

[0035] There are two positioning cylinders 36, which are respectively and fixedly installed on the die sliders 37. Each group of die plates 38 consists of two and is respectively slidably connected in the chute 33.

[0036] The fixed housing includes a lower plate 34 fixed to the support tooling, two vertical plates 32 symmetrically fixed to the lower plate 34, and an upper plate 31 fixed to the tops of the two vertical plates 32. The servo cylinders II 35 are respectively fixed to the opposite side faces of the upper plate 31 and the lower plate 34.

[0037] During use: The servo cylinders II 35 drive the corresponding die sliders 37 to displace relatively or away from each other. The die sliders 37 drive the upper and lower dies of the corresponding die plates 38 to displace, so that the dies on the die plates 38 extrude the copper wire to achieve the purpose of 3D stamping forming.

[0038] When replacement is needed, the servo cylinders II 35 drive the die sliders 37 to displace away from each other, so that the distance between the two die plates 38 is large enough for the clamping block 65 to be inserted. Then the automatic die-changing assembly 6 moves the clamping block 65 between the two die plates 38. Then, the servo cylinders II 35 drive the die sliders 37 to displace along the chute 33 until they are aligned with the card slots 55 on the die clamping block 53. At this time, the through slot 30 is inserted into the clamping block 65. Then the output shafts of the positioning cylinders 36 retract. The automatic die-changing assembly 6 drives the die plate 38 into the die tooling 5 through the clamping block 65. Then the die tooling 5 displaces the die plate 38 to be replaced until it can slide into the chute 33. Then the automatic die-changing assembly 6 drives the die plate 38 into the chute 33 through the clamping block 65. Then the positioning cylinders 36 reset and limit the die plate 38. The servo cylinders II 35 drive the two die plates 38 to displace away from each other, so that the clamping block 65 can be disengaged from the through slot 30 and reset under the action of the automatic die-changing assembly 6, and the die change is completed.

[0039] In this embodiment, the die tooling 5 includes two vertical slide plates 52 and a plurality of die clamping blocks 53. The vertical slide plates 52 are fixed with a plurality of sliders 51 that are slidably connected in the support tooling. The vertical slide plates 52 are provided with a plurality of grooves that are fixedly matched with the die clamping blocks 53. Both the upper and lower side faces of the die clamping blocks 53 are provided with card slots 55 for the die plates 38 to slide. The card slots 55 can be mutually connected with the chute 33. The die clamping blocks 53 are provided with through slots 56 for the clamping blocks 65 to pass through.

[0040] During use, under the action of the support tooling, the vertical slide plates 52 displace up and down. The vertical slide plates 52 drive the card slots 55 on the die clamping blocks 53 to be mutually connected with the chute 33. Then the die plate 38 can be replaced, which is convenient for replacing the die plate 38.

[0041] Through the setting of the through slot 56, when the mold clamping block 53 moves up and down, it is convenient for the clamping block 65 to pass through the mold clamping block 53, ensuring that the corresponding mold plate 38 is driven to move.

[0042] In this embodiment, the automatic mold changing assembly 6 includes a mounting plate 63 fixed to the side of the support tooling, a cylinder 62 fixed to the mounting plate 63, and a push rod 61 slidably disposed on the mounting plate 63. The cylinder 62 is connected to the push rod 61, and the clamping block 65 is fixedly installed on the push rod 61.

[0043] During use, the clamping block 65 is driven to move by the cylinder 62 and the push rod 61, thereby ensuring that the corresponding mold plate 38 moves.

[0044] In this embodiment, a joint 64 is installed at the output end of the cylinder 62, and the joint 64 is fixedly connected to the upper side wall of the push rod 61;

[0045] In this embodiment, the support tooling includes two symmetrically arranged L-shaped support seats 4, a top plate 2 fixed to the tops of the two L-shaped support seats 4, and a servo cylinder 1 fixed to the top plate 2. The mounting plate 63 and the lower plate 34 are both fixed to the two L-shaped support seats 4. The slider 51 is slidably connected to the inner sides of the two L-shaped support seats 4. The output end of the servo cylinder 1 passes through the top plate 2 and is fixedly connected to the vertical slide plate 52;

[0046] During use, the vertical slide plate 52 is driven to move up and down by the servo cylinder 1, facilitating the alignment of different card slots 55 with the sliding grooves 33;

[0047] Among them, the through slot 30, the through slot 56, and the clamping block 65 are aligned. When the servo cylinder 1 drives the vertical slide plate 52 to move up and down, the clamping block 65 passes through the through slot 56 on the mold clamping block 53 and can be engaged with the through slot 30 on the mold plate 38 that needs to be reconfigured, preparing for subsequent reconfiguration.

[0048] In this embodiment, the mold plate 38 is provided with a positioning hole 381 for inserting the positioning cylinder 36.

[0049] During use, the positioning cylinder 36 is inserted into the positioning hole 381 so that the mold plate 38 is limited and fixed, preventing the mold plate 38 from shifting during the stamping process, resulting in misalignment of the copper wire stamping and obtaining unqualified 3D formed copper wires, ensuring the stability of stamping.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
