Referring to fig. 4 and 5, an insulation paper hot press shaping jig comprises a machine table 1, a machine frame 2, a shaping assembly 4 and two groups of first ejection assemblies 3. Wherein, two sets of first ejector components 3 are installed on board 1, and shaping subassembly 4 is located on frame 2. In this embodiment, the frame 2 is fixed on the machine 1.

Referring to fig. 5 and 6, specifically, the first ejector assembly 3 includes a first ejector block 301, and the first ejector block 301 is located on the top surface of the machine 1. The first ejector block 301 includes a first ejector surface 301b and a bearing surface 301a, the two first ejector surfaces 301b being mutually oriented and spaced apart in the second direction to form a molding passage 3a between the two first ejector surfaces 301 b. In this embodiment, the second direction is the front-rear direction, i.e. the Y-axis direction in the figure. The bearing surface 301a is a top surface of the first pushing block 301, and is used for supporting the insulating paper a. When the insulating paper a is folded and overlapped, the insulating paper a is firstly placed on the bearing surface 301a of the first pushing blocks 301, and the insulating paper a is simultaneously supported by the two first pushing blocks 301, and further, the areas of the insulating paper a on the two first pushing blocks 301 are consistent.

Referring to fig. 5 and 6, the molding assembly 4 includes a molding block 401 and a molding driving member 402, where a fixed end of the molding driving member 402 is fixed on the frame 2 by a bolt, and the driving end of the molding driving member 402 is fixed with the molding block 401 by a bolt to drive the molding block 401 to move in a third direction, in this embodiment, the third direction is a vertical direction, that is, a Z-axis direction in the drawing. The molding block 401 is located above the molding passage 3a, and as the molding block 401 descends, the molding block 401 protrudes into the molding passage 3a.

Referring to fig. 2, 6-9, when the insulating paper a is folded, the insulating paper a is first transplanted onto the bearing surface 301a by the external suction cup, and the insulating paper a is supported by the two first pushing blocks 301. The molding block 401 is driven by the molding driving member 402 to descend into the molding channel 3a, so that the insulating paper a is pushed into the molding channel 3a by the portion of the insulating paper a above the molding channel 3a, and the insulating paper a is pressed into the molding channel 3a. Finally, the molding block 401 presses a portion of the insulating paper a against the top surface of the machine 1, and the remaining portions of the insulating paper a are respectively attached to both side walls of the molding passage 3a, so that the insulating paper a has a slot bottom shielding portion a1 shielding the slot bottom of the iron core b mounting slot b1 and two slot wall shielding portions a2 shielding the two slot walls of the iron core b mounting slot b1.

In this embodiment, the length direction of the molding passage 3a is set along a first direction, which is the left-right direction, i.e., the X-axis direction in the drawing. The height of the molding passage 3a is in the third direction, and in the vertical direction, i.e., in the Z-axis direction in the drawing. The width direction of the molding passage 3a is the second direction, and the front-rear direction, that is, the Y-axis direction in the drawing.

Referring to fig. 5 and 6, the length direction of the molding block 401 is consistent with the length direction of the molding channel 3a, and the length of the bottom surface of the molding block 401 is consistent with the length of the molding channel 3a, so as to contact with the insulation paper a extending into the molding channel 3a to the maximum extent, increase the contact surface area with the insulation paper a, facilitate the uniform bending of the insulation paper a, and improve the folding quality of the insulation paper a.

Referring to fig. 8-10, further, the first ejector assembly 3 further includes a first ejector driving member 302, and the first ejector driving member 302 is mounted on the machine table 1 and is in driving connection with the first ejector block 301. The two first pushing blocks 301 are respectively driven by the two first pushing driving members 302 to approach or move to each other, so as to reduce or enlarge the width of the forming channel 3a. In this embodiment, the first ejector driver 302 includes an air cylinder. When the molding block 401 descends to abut against the top surface of the machine 1, the two first pushing blocks 301 approach each other to abut against the opposite side surfaces of the molding block 401.

In this way, after the insulating paper a is pressed on the top surface of the machine 1 by the forming block 401, the two first pushing blocks 301 are close to each other, and the insulating paper a is fully folded by pressing the portions of the insulating paper a on the opposite sides of the forming block 401 on the forming block 401. It will be appreciated that the insulating paper a has one slot bottom shielding portion a1 and two slot wall shielding portions a2 after being folded, the slot bottom shielding portion a1 is located between the forming block 401 and the machine table 1, and the slot wall shielding portion a2 is located between the forming block 401 and the first pushing block 301. The molding block 401 abuts against the machine table 1, and the first pushing block 301 abuts against the molding block 401, so that the shape of the insulating paper a is shaped conveniently, and the possibility that the insulating paper a returns due to self elastic force is reduced.

Referring to fig. 5 and 6, further, the first ejection surfaces 301b are disposed at an acute angle to the receiving surface, so that the molding passage 3a formed between the two first ejection surfaces 301b is in a shape of narrow top and wide bottom. Correspondingly, the side surface of the molding block 401, which is matched with the first pushing surface 301b, is also inclined relative to the horizontal plane, and is matched with the first pushing surface 301b, and the first pushing surface 301b can be completely adhered to the side surface of the molding block 401.

Referring to fig. 2 and 5, the two first push blocks 301 are disposed so as to approach each other and abut on the molding block 401, and then the groove wall shielding portion a2 formed by folding the insulating paper a is disposed at an acute angle to the groove bottom shielding portion a1, and the two groove wall shielding portions a2 are disposed in an inner buckle shape. The insulating paper a formed by folding is not easy to return due to self elasticity, so that the folded state of the insulating paper a is maintained conveniently, and the folding forming quality of the insulating paper a is improved.

Further, the molding assembly 4 further includes a heating module integrated into the molding block 401 to heat the bottom surface of the molding block 401. In this embodiment, the heating module includes an electric heating wire or tube. By heating the bottom surface of the molding block 401, when the heated molding block 401 contacts the insulating paper a, the insulating paper a is heated to soften the insulating paper a, so that the insulating paper a is easily bent.

Referring to fig. 5 to 9, optionally, the insulation paper hot press shaping jig further includes a supporting component 5, where the supporting component 5 is used for supporting a suspended portion of the insulation paper a above the shaping channel 3a. Specifically, the supporting component 5 includes a supporting member 501, where the supporting member 501 vertically penetrates through the machine 1 and is elastically connected to the machine 1. The part of the supporting member 501 extending above the machine 1 is located between the two first pushing blocks 301, the supporting member 501 includes a supporting surface 501a, and when the supporting surface 501a is at the highest position, the supporting surface 501a is flush with the bearing surface 301a, so as to support the insulating paper a. When the supporting surface 501a is at the lowest position, the supporting surface 501a is flush with the top surface of the machine 1, and does not interfere with the travel of the molding block 401.

Referring to fig. 5 to 9, in the present embodiment, the molding block 401 and the supporting member 501 are disposed vertically opposite to each other, and after the molding block 401 descends, the insulating paper a is pressed against the supporting member 501, and at this time, the insulating block is clamped between the molding block 401 and the supporting member 501. As the forming block 401 further descends, the supporting member 501 is brought down elastically, and thus the clamped portion of the insulating paper a is also entered into the forming passage 3a simultaneously. Since the middle part of the insulating paper a is clamped, namely the bottom shielding part a1 of the insulating paper a is clamped, the insulating paper a is not easy to shift when the insulating paper a is bent, and therefore the folding precision of the insulating paper a is improved.

In this embodiment, the support assembly 5 further comprises a connection plate and a plurality of spring guide rods. The connecting plate is fixed with the support 501, and the connecting plate is located the bottom of board 1, stretches to the height above board 1 through the support 501 of connecting plate restriction. The plurality of spring guide rods are fixed with the machine 1, and the elastic movable ends of the plurality of spring guide rods are fixed with the connecting plate, so that the elastic connection between the supporting piece 501 and the machine 1 is realized.

Referring to fig. 5, further, the supporting surface 501a of the supporting member 501 is provided with an adsorption structure, which communicates with an external negative pressure device. After the insulating paper a is placed on the supporting surface 501a, the adsorbing structure adsorbs the insulating paper a to limit displacement of the insulating paper a when the molding block 401 is pressed down.

Referring to fig. 5-9, the first ejector assembly 3 further includes two first limiting blocks 303, where the first limiting blocks 303 are fixed on the bearing surface 301a and are disposed away from edges of the bearing surface 301a and the first ejector surface 301 b. It is understood that the two first stoppers 303 are disposed at intervals in the second direction. The supporting component 5 further comprises two second limiting blocks 502, the two second limiting blocks 502 are fixed on the supporting surface 501a and are respectively arranged close to two opposite edges of the supporting surface 501a, and the second limiting blocks 502 are located outside the forming channel 3a. It is understood that the two second limiting blocks 502 are disposed at intervals in the first direction.

Referring to fig. 5-9, in this embodiment, after the insulating paper a is placed on the bearing surface 301a, the length direction of the insulating paper a is set along the second direction, the width direction is set along the first direction, the distance between the two first limiting blocks 303 is equal to the length of the insulating paper a, and the distance between the two second limiting blocks 502 is equal to the width of the insulating paper a, so that the two first limiting blocks 303 and the two second limiting blocks 502 respectively abut against four circumferential sides of the insulating paper a, so as to position the feeding position of the insulating paper a, ensure that the feeding position of the insulating paper a is consistent each time, the folding position of the insulating paper a is consistent each time, and ensure the folding consistency of the insulating paper a.

In this embodiment, the insulation paper a to be folded includes a groove bottom shielding portion a1, two groove wall shielding portions a2, and four side wall shielding portions a3 as shown in fig. 2. The folded insulating paper a is shown in the figure, wherein the middle part of the insulating paper a is folded twice to form a groove bottom shielding part a1 and two groove wall shielding parts a2, and two sides of the two groove wall shielding parts a2 are folded to form a side wall shielding part a3.

The distance between the two second ejector blocks 601 is greater than the length of the forming channel 3a, after the two second ejector blocks 601 descend along with the forming block 401, the two second ejector blocks 601 are located outside the forming channel 3a, and the two second ejector blocks 601 are located on two opposite sides of the first ejector blocks 301 respectively, specifically, when the distance between the two first ejector blocks 301 is minimum, the projections of the two first ejector blocks 301 in the first direction are partially located on the side surface of the second ejector blocks 601 facing the first ejector blocks 301, and it can be understood that the second ejector blocks shield the opening of the forming channel 3a in the first direction.

Referring to fig. 5 and 8 to 11, when the insulating paper a is folded, the insulating paper a is placed on the carrying surface 301a, and the width of the insulating paper a is greater than the length of the forming channel 3a. When the insulating paper a is pushed by the molding block 401, the second pushing blocks 601 are respectively pressed against both ends of the groove bottom shielding portion a1 of the insulating paper a. After the insulating paper a extends to the forming channel 3a, the four side wall shielding parts a3 of the insulating paper a are all located outside the forming channel 3a, and along with the descending of the second pushing block 604, the four side wall shielding parts a3 of the insulating paper a located outside the forming channel 3a are all pushed by the second pushing block 604 to be folded.

As the first ejector pad 301 moves toward the molding pad 401, the first ejector pad 301 pushes the sidewall shielding portion a3 to move toward the second ejector pad 601, thereby further folding the sidewall shielding portion a3 with respect to the groove wall shielding portion a2, and thus completing the folding molding of the sidewall shielding portion a3.

By the arrangement, the first pushing block 301 and the second pushing block 601 are matched, so that the side wall shielding part a3 is formed by folding while the groove wall shielding part a2 is formed, and the efficiency of folding and forming the insulating paper a is improved. In addition, the side wall shielding part a3 can shield the side wall of the iron core b, so that the possibility that the coil directly contacts the iron core b is further reduced.

In this embodiment, the second ejector driver 602 includes a cylinder.

The second ejector pad 601 is elastically connected with the forming block 401 to ensure that the distance between the two second ejector pads 601 is maximum, and at this time, when the second ejector pad 601 descends together with the forming block 401, the second ejector pad 601 is ensured not to collide with the first ejector pad 301. In this embodiment, the second pushing block 601 is connected to the molding block 401 through a spring rod to achieve elastic connection of the two.

Referring to fig. 2 and 8-11, when the molding block 401 extends to the molding passage 3a, the second pushing block 601 pushes the slot wall shielding portion a2 of the insulating paper a beyond the end of the molding passage 3a synchronously, so that the slot wall shielding portion a2 is folded into a side wall shielding portion a3 beyond the end of the molding passage 3a. The driving end of the second pushing driving piece 602 drives the second pushing blocks 601 to abut against the two first pushing blocks 301, and finally the second pushing driving piece 602 drives the second pushing blocks 601 to abut against the first pushing blocks 301, so that the side wall shielding part a3 is clamped between the first pushing blocks 301 and the second pushing blocks 601, and the side wall shielding part a3 is shaped conveniently, so that the folding quality is improved.

Referring to fig. 5 and 12, in the embodiment, since the supporting surface 501a is provided with the second limiting block 502, in order to avoid the second pushing block 601 from descending and colliding with the second limiting block 502, a space avoiding groove 601a is formed in the bottom surface of the second limiting block 502. When the second pusher 601 descends, the bottom surface of the second pusher 601 and the molding block 401 simultaneously contact the insulating paper a on the supporting surface 501 a.

When the molding block 401 abuts the insulating paper a on the top surface of the machine 1, the groove bottom shielding portion a1 of the insulating paper a is pressed by the molding block 401, and the portions of the insulating paper a on two opposite sides of the molding block 401 are folded to form groove wall shielding portions a2.

Referring to fig. 7 to 11, when the second ejector pad 601 is pushed down with the molding pad 401, the second ejector pad 601 pushes the insulating paper a beyond the bearing surface 301a, that is, the end of the slot wall shielding portion a2 of the insulating paper a is folded, so that the side wall shielding portion a3 is folded and molded at the end of the slot wall shielding portion a2.

In addition, as the first push block 301 moves toward the molding block 401, the first push block 301 smoothes the side wall shielding portion a3 between the first push block 301 and the second push block 601 to improve the folding quality.

Referring to fig. 7 to 11, finally, the second push block 601 moves toward the first push block 301 to press the sidewall shielding portion a3 against the side surface of the first push block 301 to deepen the crease of the sidewall shielding portion a3 and the groove wall shielding portion a2, and shape the state of the insulating paper a.
