For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 8 As shown, a lateral core pulling device according to a preferred embodiment of the present invention includes a first mold body 10, a second mold body 20, a slider 30 and a driving member 40;

[0038] The first mold body 10 and the second mold body 20 are arranged to slide relative to each other. The first mold body 10 is provided with a sliding groove 11 and an injection cavity 12 on the side facing the second mold body 20. The injection cavity 12 and the driving member 40 are arranged on both sides of the sliding groove 11. The second mold body 20 is provided with an injection port 21, which is connected to the injection cavity 12.

[0039] The slider 30 includes a slider body 31 and a cover 36. The cover 36 is detachably connected to the slider body 31. The slider body 31 is slidably connected to the sliding groove 11. The slider body 31 is provided with a positioning opening 32 and a cover opening 33 that are interconnected. The positioning opening 32 faces the injection cavity 12, and the cover opening 33 faces the second mold body 20. The cover 36 covers the cover opening 33 to form a positioning groove 34.

[0040] The driving member 40 is connected to the first mold body 10 , and the driving member 40 is in transmission connection with the slider body 31 .

[0041] In the lateral core pulling device of the present invention, the slider 30 includes a slider body 31 and a cover 36. By providing the slider 30 in a split configuration, the slider body 31 and the cover 36 are both open structures, which reduces the difficulty of manufacturing the slider 30. When the driving member 40 drives the slider body 31 to the injection molding position, the slider body 31 is then assembled with the copper busbar 50, reducing the number of relative sliding movements between the connecting end 52 of the copper busbar 50 and the slider 30, thereby reducing the risk of surface damage to the copper busbar 50. When the copper busbar 50 and the slider 30 are assembled before injection molding, the slider body 31 is in an open state, and the connecting end 52 of the copper busbar 50 is placed into the positioning groove 34 through the cover 33. One end of the connecting end 52 extends out of the injection molding cavity 12 from the positioning groove 32. After the connecting end 52 is positioned, the copper busbar body 51 is placed into the injection molding cavity 12, and the cover body 36 is then placed on the cover 33 so that the connecting end 52 is surrounded by the positioning groove 34, thereby avoiding the risk of mold compression caused by the insertion position of the copper busbar 50 not being consistent with the center of the positioning groove 34. At the same time, since there is no risk of mold compression, there is no need to enlarge the size of the positioning groove 34. The shape of the positioning groove 34 corresponds to the shape of the connecting end 52 of the copper busbar 50. The connection between the positioning groove 34 and the connecting end 52 of the copper busbar 50 is highly matched, thereby avoiding the problem of flashing at the sealing of the copper busbar 50 after injection molding.

[0042] As one embodiment, the inner peripheral wall of the positioning groove 34 is in contact with the outer peripheral surface of the connecting end 52 of the copper busbar 50 .

[0043] Furthermore, the cover 36 is connected to the slider body 31 via a magnet, which is easy to operate and helps to improve the injection molding efficiency.

[0044] Further, such as Figures 3 and 4As shown, the slider 30 has the copper bar 50 placed. When the slider 30 is in the copper bar 50 assembly state, the driving member 40 drives the slider body 31 to move toward the injection cavity 12, so that the slider 30 actively moves to the injection position, facilitating the placement of the connecting end 52 of the copper bar 50 and the positioning of the connecting end 52 at the injection position. The cover 36 is separated from the slider body 31 to facilitate the placement of the connecting end 52 of the copper bar 50 into the positioning groove 34 through the cover opening 33, avoiding relative movement between the slider 30 and the connecting end 52, avoiding the risk of compression molding, and reducing the risk of scratching the surface of the copper bar 50.

[0045] Further, such as Figures 1 to 4 As shown, the slider 30 further includes a base 39, a plurality of slider bodies 31 are provided, and the sides of the plurality of slider bodies 31 facing away from the positioning groove 34 are connected to the base 39, and the driving member 40 is connected to the base 39. The plurality of slider bodies 31 are connected by the base 39 to form an integral slider 30. The driving member 40 is connected to the base 39, driving the plurality of slider bodies 31 to move synchronously, and can perform injection molding on a copper busbar 50 having a plurality of connection ends 52.

[0046] Further, such as Figures 1 to 4 As shown, the extension direction of the seat body 39 is perpendicular to the sliding direction of the slider body 31, and multiple slider bodies 31 are arranged at intervals along the extension direction of the seat body 39 to meet the injection molding processing requirements of the copper busbar 50 with multiple connection ends 52.

[0047] Further, such as Figures 1 to 4 As shown, the cover 36 includes a cover portion 37 and a connecting portion 38. One end of the cover portion 37 is connected to the connecting portion 38, and both sides of the connecting portion 38 protrude from the cover portion 37. The slider body 31 is provided with a connecting groove 35. The cover portion 37 is covered on the cover opening 33 and is snapped into the connecting groove 35. The cover portion 37 is covered on the cover opening 33 and forms a positioning groove 34 with the slider body 31 for accommodating the connecting end 52 of the copper busbar 50. The connecting portion 38 is located at the end of the cover 36 away from the injection cavity 12, and the connecting groove 35 is located at the end of the slider body 31 away from the injection cavity 12. The connecting portion 38 is snapped into the connecting groove 35 to position the cover 36 on the connecting groove 35 and achieve connection with the slider body 31. When the driving member 40 drives the slider body 31 to slide, the cover 36 can move synchronously with the slider body 31.

[0048] As one embodiment, Figures 1 to 4 As shown, the extension direction of the positioning groove 34 is the same as the sliding direction of the slider 30, the extension direction of the connecting groove 35 is perpendicular to the sliding direction of the slider 30, and the connecting portion 38 is clamped in the connecting groove 35 to limit the connecting portion 38 in the sliding direction, thereby realizing that the slider 30 drives the cover body 36 to move synchronously when sliding.

[0049] As one embodiment, Figures 1 to 4 As shown, a first magnet is provided on the side of the connecting portion 38 facing the connecting groove 35, and a second magnet is provided on the side of the connecting groove 35 facing the connecting portion 38. The first magnet and the second magnet are magnetically connected, thereby improving the connection convenience between the connecting portion 38 and the sliding body. Of course, in addition to magnetic connection, other detachable connection methods are also possible, such as threaded connection or snap connection.

[0050] As one embodiment, Figures 2 to 5 As shown, the sliding groove 11 is provided with a first limiting portion 13, which is located on the side of the sliding groove 11 facing the injection cavity 12. The first limiting portion 13 protrudes toward the second mold body 20, and the seat body 39 protrudes toward the first mold body 10 to form a second limiting portion 391. The limiting portion slides in the sliding groove 11. When the slider 30 slides to the injection position, the second limiting portion 391 abuts against the first limiting portion 13 on the side facing the injection cavity 12. The first limiting portion 13 and the second limiting portion 391 are arranged to limit the slider body 31 to the injection position, improving the connection and fit between the slider body 31 and the connecting end 52.

[0051] A processing method for a lateral core pulling device, such as Figures 1 to 8 As shown, a copper busbar 50 is injection molded by a lateral core pulling device, wherein the copper busbar 50 includes a copper busbar body 51 and a connecting end 52, one end of the connecting end 52 is connected to the copper busbar body 51 to form a whole. The outer periphery of the copper busbar body 51 is injection molded to form a plastic layer 53, including the following steps:

[0052] The assembly steps of the copper busbar 50 and the slider 30 are as follows: before injection molding the copper busbar 50, the first mold body 10 and the second mold body 20 are separated, and the driving member 40 drives the slider body 31 to move toward the injection cavity 12 to the injection position. The slider body 31 is in an open state, and the connecting end 52 is placed into the positioning groove 34 from the cover 33. One end of the connecting end 52 extends out of the positioning opening 32 into the injection cavity 12. The copper busbar body 51 is placed in the injection cavity 12, and the cover body 36 is covered on the cover 33. The assembly of the copper busbar 50 and the slider 30 before injection molding is completed.

[0053] In the processing method of the lateral core pulling device of the present invention, the first mold body 10 is separated from the second mold body 20 so as to provide assembly space for the slider body 31 and the copper busbar 50 after the slider body 31 moves to the injection molding position. The driving member 40 drives the slider body 31 to move back and forth in the sliding groove 11 toward or away from the injection molding cavity 12. When the slider body 31 moves toward the injection molding cavity 12 to the injection molding position, the slider body 31 is in an open state, the cover 33 faces the second mold body 20, and the connecting end 52 can be placed into the positioning groove 34 from the cover 33 and accommodated in the positioning groove 34 to realize the positioning of the connecting end 52. Since the connecting end 52 and the copper busbar body 51 are an integral whole, one end of the connecting end 52 extends out of the injection molding cavity 12 from the positioning opening 32, and the copper busbar body 51 is placed in the injection molding cavity 12. The cover body 36 is covered on the cover 33 to complete the assembly of the copper busbar 50 and the slider 30 before injection molding. During the assembly process, the connection end 52 is prevented from sliding relative to each other in the positioning groove 34 of the slider body 31, the number of relative sliding between the connection end 52 of the copper busbar 50 and the slider 30 is reduced, and the risk of scratching the surface of the copper busbar 50 is reduced. The connection end 52 of the copper busbar 50 is placed into the positioning groove 34 from the cover 33. The connection end 52 is first positioned in the positioning groove 34 and then the copper busbar body 51 is placed in the injection molding cavity 12, thereby avoiding the risk of die stamping due to the inconsistency between the insertion position of the copper busbar 50 and the center of the jack. At the same time, since there is no die stamping risk, there is no need to enlarge the size of the positioning groove 34. The shape of the positioning groove 34 corresponds to the shape of the connection end 52 of the copper busbar 50. The connection between the positioning groove 34 and the connection end 52 of the copper busbar 50 is highly matched, thereby avoiding the problem of burrs at the sealing part of the copper busbar 50 after injection molding.

[0054] Furthermore, after the copper busbar 50 and the slider 30 are assembled, the copper busbar 50 is also molded. The first mold body 10 and the second mold body 20 are moved relatively close together to close the mold. Raw material for the plastic layer 53 is injected through the injection port 21. The raw material enters the injection cavity 12 and forms the plastic layer 53 around the outer periphery of the copper busbar body 51, completing the injection molding of the copper busbar 50. The first mold body 10 and the second mold body 20 are moved relatively close together to close the injection cavity 12. Raw material is injected from the injection port 21 into the injection cavity 12 so that the raw material forms a plastic layer 53 on the copper busbar body 51.

[0055] Furthermore, after the copper busbar 50 injection molding step, a mold opening step is also included, in which the first mold body 10 and the second mold body 20 are moved away from each other to open the injection cavity 12, and the driving member 40 drives the slider body 31 and the cover body 36 to move in a direction away from the injection cavity 12, so that the connection end 52 is disengaged from the positioning groove 34, and the cover body 36 is removed from the slider body 31. The cover body 36 is connected to the slider body 31, so that the driving member 40 drives the slider body 31 to move, and the slider body 31 drives the cover body 36 to move synchronously. As the slider body 31 moves away from the injection cavity 12, the connection end 52 is disengaged from the positioning groove 34. Since the inner peripheral wall of the positioning groove 34 is in contact with the outer peripheral wall of the connection end 52, the assembly matching degree of the positioning groove 34 and the connection end 52 is high, and the edge area of ​​the plastic layer 53 facing the positioning opening 32 does not insert into the positioning opening 32, thereby avoiding the problem of flashing at the sealing part of the copper busbar 50 after injection molding.

[0056] Furthermore, after the mold opening step, a product removal step is also included, such as Figure 7 As shown, the first mold body 10 has an ejector pin 41 that can move up and down along the height direction of the first mold body 10. One end of the ejector pin 41 is located below the corresponding copper bar 50. The ejector pin 41 moves toward the copper bar body 51 to eject the copper bar body 51, and then the ejector pin 41 returns to its original position. The ejector pin 41 ejects the copper bar body 51, making it easier to remove the copper bar 50 after injection.

[0057] As one embodiment, the ejector pin 41 can be driven to move up and down by a cylinder.

[0058] In summary, the embodiments of the present invention provide a lateral core pulling device and a processing method thereof. The slider 30 includes a slider body 31 and a cover body 36. By providing the slider 30 in a split configuration, the slider body 31 and the cover body 36 are both open structures, which reduces the processing difficulty of the slider 30. When the driving member 40 drives the slider body 31 to move to the injection molding position, the slider body 31 is then assembled with the copper busbar 50, reducing the number of relative sliding movements between the connecting end 52 of the copper busbar 50 and the slider 30, thereby reducing the risk of surface damage to the copper busbar 50. When the copper busbar 50 and the slider 30 are assembled before injection molding, the slider body 31 is in an open state, and the connecting end 52 of the copper busbar 50 is placed into the positioning groove 34 through the cover 33. One end of the connecting end 52 extends out of the injection molding cavity 12 from the positioning groove 32. After the connecting end 52 is positioned, the copper busbar body 51 is placed into the injection molding cavity 12, and the cover body 36 is then placed on the cover 33 so that the connecting end 52 is surrounded by the positioning groove 34, thereby avoiding the risk of mold compression due to the insertion position of the copper busbar 50 not being consistent with the center of the jack. At the same time, since there is no risk of mold compression, there is no need to enlarge the size of the positioning groove 34. The shape of the positioning groove 34 corresponds to the shape of the connecting end 52 of the copper busbar 50. The connection between the positioning groove 34 and the connecting end 52 of the copper busbar 50 is highly matched, thereby avoiding the problem of flashing at the seal of the copper busbar 50 after injection molding.

[0059] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
