Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] An electromagnetic mold preheating machine, comprising:

[0032] Preheater body 1;

[0033] The support frame 3 is fixedly connected to the surface of the preheater body 1;

[0034] The sliding assembly includes a sleeve 6, a first sliding plate 7, a second sliding plate 8, a second sleeve 9, a heating wire 25, a third sleeve 26, and a third sliding plate 27. Two sleeves 6, two first sliding plates 7, and two second sliding plates 8 are provided. Multiple heating wires 25 are provided. The second sleeve 9 is fixedly connected to the upper end of the preheater body 1. Both second sliding plates 8 are slidably connected to the inner wall of the second sleeve 9. Two sleeves 6 are respectively fixedly connected to the upper ends of the two second sliding plates 8. Two first sliding plates 7 are respectively slidably connected to the inner walls of the two sleeves 6. The third sleeve 26 is fixedly connected to the upper end of one of the first sliding plates 7. The third sliding plate 27 is slidably connected to the inner wall of the third sleeve 26 and fixedly connected to the upper end of the other first sliding plate 7. Multiple heating wires 25 are respectively disposed within the third sleeve 26, the third sliding plate 27, the two sleeves 6, and the two first sliding plates 7.

[0035] The drive assembly includes a first drive component, a second drive component, and a third drive component, wherein the first drive component is provided in two sets.

[0036] In a specific embodiment of this utility model, by retracting the two first sliding plates 7 and sliding them toward the inner walls of the two sleeves 6, the height of the heating wire 25 from the heating mold is adjusted; by adjusting the two second sliding plates 8 and sliding them toward the inner wall of the second sleeve 9, the third sliding plate 27 will be driven to slide toward the inner wall of the third sleeve 26. By using this device, when the electromagnetic mold preheater heats the mold, due to different mold specifications, the sliding components are controlled to adjust the distance of each heating wire 25 to the mold to be the same, so that the mold surface is heated evenly, which can reduce product defects caused by temperature difference, reduce the defect rate, and improve production efficiency.

[0037] Please refer to the details. Figures 1-7 Each drive assembly includes a fourth gear 17, a toothed belt 18, and a second motor 19. The second motor 19 is fixedly connected to the surface of the sleeve 6. The output end of the second motor 19 passes through the inner wall of the sleeve 6 and the first sliding plate 7. The fourth gear 17 is fixedly connected to the output end of the second motor 19. The toothed belt 18 is fixedly connected to the inner wall of the first sliding plate 7. The toothed belt 18 meshes with the fourth gear 17.

[0038] In this embodiment: the surface of the first sliding plate 7 is provided with a sliding groove. When the second motor 19 rotates, it drives the fourth gear 17 to rotate. At this time, the toothed belt 18 that meshes with the fourth gear 17 will move up and down.

[0039] Please refer to the details. Figures 1-7 The second driving component includes a third motor 20, a bidirectional screw 21, a second fixing block 22, a fifth gear 23, and a sixth gear 24. There are two second fixing blocks 22. The third motor 20 is fixedly connected inside the preheater body 1. The sixth gear 24 is fixedly connected to the output end of the third motor 20. The bidirectional screw 21 is rotatably connected to the inner wall of the support frame 3. The fifth gear 23 is fixedly connected to the middle of the circumferential surface of the bidirectional screw 21. The two second fixing blocks 22 are respectively fixed to the lower ends of the two second sliding plates 8. The two second fixing blocks 22 are threadedly connected to the bidirectional screw 21.

[0040] In this embodiment: the third motor 20 drives the sixth gear 24 to rotate, and the sixth gear 24 drives the meshing fifth gear 23 to rotate. At this time, the bidirectional screw 21 will rotate together. Because the bidirectional screw 21 is a bidirectional screw with opposite threads from the middle to both ends, the two second fixing blocks 22 will move inward or outward at the same time when the bidirectional screw 21 rotates.

[0041] Please refer to the details. Figures 1-7 The surface of the preheater body 1 is equipped with a switch 4, and support legs 2 are fixed at the four corners of the lower end of the preheater body 1.

[0042] In this embodiment: switch 4 controls the operation of the equipment, and support leg 2 supports the equipment.

[0043] Please refer to the details. Figures 1-7 The upper end of the second sleeve 9 is rotatably connected to a storage tray 5.

[0044] In this embodiment, the tray 5 serves to hold the mold.

[0045] Please refer to the details. Figures 1-7 The third driving component includes a first gear 12, a fixed block 13, a second gear 14, a connecting rod 28, a third gear 15, and a first motor 16. There are two first gears 12. The first motor 16 is fixedly connected to the surface of the second sleeve 9. The second gear 14 is fixedly connected to the output end of the first motor 16. The fixed block 13 is fixedly connected to the upper end of the second sleeve 9. The connecting rod 28 is rotatably connected to the inner wall of the fixed block 13. The two first gears 12 are respectively fixedly connected to the two ends of the connecting rod 28. The third gear 15 is fixedly connected to the circumferential surface of the tray 5. One of the first gears 12 meshes with the second gear 14, and the other first gear 12 meshes with the third gear 15.

[0046] In this embodiment: the rotation of the second gear 14 drives one of the first gears 12 to rotate, and the connecting rod 28 drives another first gear 12 to rotate, which in turn drives the third gear 15 meshing with the first gear 12 to rotate, thereby causing the tray 5 to rotate, which helps the mold to be heated evenly.

[0047] It should be noted that the specific models of the second motor 19, the third motor 20, and 16 used shall be selected by those skilled in the art, and the above-mentioned second motor 19, third motor 20, and 16 are all existing technologies, which will not be elaborated in this solution.

[0048] The working principle and usage process of this utility model are as follows: The second motor 19 rotates, driving the fourth gear 17 to rotate. At this time, the toothed belt 18 meshing with the fourth gear 17 moves up and down, causing the two first sliding plates 7 to slide. By retracting the two first sliding plates 7, they slide towards the inner walls of the two sleeves 6, adjusting the height of the heating wire 25 from the heating mold. The third motor 20 drives the sixth gear 24 to rotate, which in turn drives the meshing fifth gear 23 to rotate. At this time, the bidirectional screw 21 rotates along with it. Because the bidirectional screw 21 is a bidirectional screw with opposite threads from the middle to both ends, the two first... When the bidirectional screw 21 rotates, the two fixed blocks 22 can move inward or outward simultaneously. Then, the two second sliding plates 8, which are fixedly connected to the two second fixed blocks 22 respectively, will slide towards the inner wall of the second sleeve 9. At this time, the third sliding plate 27 will slide towards the inner wall of the third sleeve 26 to adjust the distance between the heating line 25 and the heating mold. By using this device, when the electromagnetic mold preheater heats the mold, the distance between each heating line 25 and the mold can be adjusted to be the same due to different mold specifications. This makes the mold surface heat up evenly, which can reduce product defects caused by temperature difference, reduce the defect rate, and improve production efficiency.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
