[0036] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purposes, the specific embodiments of the present application are described in detail below in combination with the drawings and preferred embodiments.

[0037] Please refer to Figure 1 , Figure 2 , Figures 5 to 7 The present embodiment provides an injection mold for the heating seat of an electronic cigarette, which comprises a lower mold 1 and an upper mold 2 arranged above the lower mold 1. A mold core structure 3 is arranged on the lower mold 1. The mold core structure 3 comprises a first slider 31 and a second slider 32 arranged oppositely, and a plurality of mold cores 33 arranged between the first slider 31 and the second slider 32. The first slider 31, the second slider 32 and the mold cores 33 combine to form a plurality of mold cavities 34. When injecting, the injection nozzle on the upper mold 2 injects glue into the mold cavities 34, and a plurality of plastic parts 20 are formed in the mold cavities 34, as shown in Figure 3 and Figure 4 . At the same time, a plurality of protrusions (310, 320) are formed at the ends of the first slider 31 and the second slider 32, respectively. The plurality of protrusions (310, 320) and the mold cores 33 combine to form the internal shape of the mold cavities 34. When injecting glue into the mold cavities 34, the plastic parts 20 with the required shape are obtained. For example, the plurality of protrusions (310, 320) on the ends of the first slider 31 and the second slider 32 correspond to the hole structure on the plastic part 20 formed by injection molding.

[0038] In the present embodiment, the plastic part 20 is formed on the metal conductive needle 101 on the material belt 10. After the plastic part 20 is formed, it is combined with the metal conductive needle 101 to form a whole, as shown in Figure 15 . In order for the material belt 10 with the metal conductive needle 101 to enter the mold cavity 34 smoothly without interfering with each other, the bending angle of the metal conductive needle 101 on the material belt 10 entering the injection mold is usually 95°-100°, and the bending angle of the metal conductive needle 101 of the final product is 90°. Therefore, a plurality of angle adjustment push blocks 311 are arranged in the first slider 31 towards the side of the mold core 33, as shown in Figure 6 , which are used to adjust the bending angle of the metal conductive needle 101 to 90°, so that the bending angle of the metal conductive needle 101 on the material belt 10 meets the product requirements.

[0039] Specifically, asFigure 7 and Figure 8 As shown, two limiting grooves 331 for inserting metal guide pins are formed on the side of the core 33. A pushing inner guide slope 3311 is formed on the inner walls of each of the two limiting grooves 331. When the strip 10 enters the lower mold 1 of the injection mold, the two metal guide pins 101 are inserted into the two limiting grooves 331. Simultaneously, as... Figure 9 As shown, two pushing parts 3111 are formed at the end of the angle adjustment push block 311. On each side of these two pushing parts 3111, an outer pushing guide slope 3112 is formed, matching the inner pushing guide slope 3311. The pushing part 3111 at the end of the angle adjustment push block 311 directly pushes the metal conductive needle 101, causing the pushing part 3111 to embed into the limiting groove 331 and directly act on the metal conductive needle 101. Under the combined action of the inner pushing guide slope 3311 of the limiting groove 331 and the outer pushing guide slope 3112 of the pushing part 3111, the bending angle of the metal conductive needle 101 is pushed to 90°. The power source for the angle adjustment push block 311 is the first slider 31, and the angle adjustment push block 311 slides together with the first slider 31. When the first slider 31 slides towards the core 33, the angle adjustment push block 311 also slides towards the core 33, thereby applying force to the metal conductive pin 101. Through the special structural design of the angle adjustment push block 311 in conjunction with the core 33, the bending angle of the metal conductive pin 101 on the material strip 10 is adjusted, ensuring that the bending angle of the metal conductive pin 101 on the material strip 10 meets product requirements. The entire process is smooth, fast, stable, and efficient.

[0040] For the opening and closing control of the mold core structure 3, this embodiment provides an opening and closing drive structure 4 connected to the mold core structure 3 on the lower mold 1, such as... Figure 4 As shown, at the same time, Figure 10 As shown, an opening and closing pin structure 5 is provided on the lower end face of the upper mold 2, facing the opening and closing driving structure 4. The opening and closing pin structure 5 drives the movement of the opening and closing driving structure 4 to control the sliding of the first slider 31 and the second slider 32, thereby realizing the opening and closing between the first slider 31 and the second slider 32.

[0041] Specifically, such as Figure 10 As shown, the opening and closing pin structure 5 includes several opening and closing pins 51 disposed on the lower end face of the upper mold 2, which are inclined from top to bottom toward the outer side of the mold core structure 3. Meanwhile, as... Figure 4As shown, the opening and closing driving structure 4 includes a first opening and closing driving block 41 slidably arranged on the lower mold 1 and connected to the first sliding block 31, and a second opening and closing driving block 42 slidably arranged on the lower mold 1 and connected to the second sliding block 32, wherein at least one insertion hole (410, 420) for the opening and closing pin 51 is formed on the first opening and closing driving block 41 and the second opening and closing driving block 42, respectively. When injection molding, the upper mold 2 is closed to the lower mold 1, so that the opening and closing pin 5 is inserted into the insertion hole (410, 420) on the corresponding first opening and closing driving block 41 and second opening and closing driving block 42. Since the opening and closing pin 5 is inclined from top to bottom to the outside of the mold core structure 3, when the opening and closing pin 5 is gradually inserted into the insertion hole (410, 420), the first opening and closing driving block 41 and the second opening and closing driving block 42 are forced to move towards the mold core 33, thereby driving the first sliding block 31 and the second sliding block 32 to slide towards each other, so that the first sliding block 31, the second sliding block 32 and the mold core 33 form a plurality of mold cavities 34, and then the plastic is injected into the mold cavity 34 to perform injection molding operation to form the plastic part 20 on the metal conductive needle 101 of the material belt 10. At the same time, the sliding of the first sliding block 31 drives the angle adjusting push block 311 to slide towards the mold core 33 synchronously, so as to realize the angle adjusting push block 311 adjusting the bending angle of the metal conductive needle 101 on the material belt 10. After the injection molding is completed, the upper mold 2 is removed from the lower mold 1, that is, the mold is opened. Since the opening and closing pin 5 is inclined from top to bottom to the outside of the mold core structure 3, when the opening and closing pin 5 is gradually extended out of the insertion hole (410, 420), the first opening and closing driving block 41 and the second opening and closing driving block 42 are forced to move away from the mold core 33, thereby driving the first sliding block 31 and the second sliding block 32 to slide away from each other, and finally the first sliding block 31 and the second sliding block 32 are away from the injection molded part 20, which is convenient for subsequent demolding operation.

[0042] By combining the opening and closing driving structure 4 with the opening and closing pin structure 5 with special structure design, the movement of the opening and closing driving structure 4 is driven by the opening and closing pin structure 5, so as to control the sliding of the first sliding block 31 and the second sliding block 32, and realize the opening and closing between the first sliding block 31 and the second sliding block 32. Therefore, it is not only convenient to complete the injection molding operation and demolding operation, but also convenient to adjust the bending angle of the metal conductive needle 101 on the material belt 10 by the angle adjusting push block 311 driven by the first sliding block 31. The cooperation between the structures is close, and the realization of each function is orderly, smooth, fast, stable, efficient, which is conducive to significantly improving the injection molding processing efficiency.

[0043] In this embodiment, as shown in Figure 11As shown, a product demolding mechanism 6 is arranged below the lower mold 1, which includes a tape ejection demolding assembly 61 for ejecting the tape 10 and an injection molded part ejection demolding assembly 62 arranged below the tape ejection demolding assembly 61 for ejecting the plastic part 20, thereby completing the demolding operation.

[0044] Specifically, the tape ejection demolding assembly 61 includes an upper top plate 611 and a plurality of ejector rods 612 arranged on the upper top plate 611 and towards the side edges of the tape 10. By controlling the upward movement of the upper top plate 611, the plurality of ejector rods 612 can be driven to move upward, thereby ejecting the tape 10 upward by the plurality of ejector rods 612. Meanwhile, the injection molded part ejection demolding assembly 62 includes a lower top plate 621 arranged below the upper top plate 611 and a plurality of ejector pins 622 arranged on the lower top plate 621 and movable through the core 33 and towards the lower end of the injection molded part 20. By controlling the upward movement of the lower top plate 621, the plurality of ejector pins 622 can be driven to move upward, thereby ejecting the plastic part 20 upward by the plurality of ejector pins 622.

[0045] In order to better install the ejector pins 622, the lower top plate 621 of the present embodiment mainly consists of a middle top plate 6211 arranged below the upper top plate 611 and a bottom plate 6212 arranged below the middle top plate 6211, wherein the lower part of the ejector pins 622 is clamped between the middle top plate 6211 and the bottom plate 6212.

[0046] As for the power source of the upper top plate 611 and the lower top plate 621, the present embodiment is provided with a lower fixed plate 63 at the lower end surface of the lower top plate 621, which is provided with a demolding driving rod 64 connected to the upper top plate 611, as shown. Figure 12 The demolding driving rod 64 of the present embodiment is directly driven by the driving cylinder inside the injection mold. When the driving cylinder drives the demolding driving rod 64 to move upward, the upper top plate 611 and the lower top plate 621 can be driven to move upward by the demolding driving rod 64, thereby completing the demolding operation.

[0047] In order to more smoothly and quickly demold the tape 10 and the plastic part 20, the present embodiment is provided with at least one segmented ejection mechanism 7 on the side of the product demolding mechanism 6, as shown. Figure 11 、 Figure 13 and Figure 14As shown, the sectional ejection mechanism 7 comprises a linkage vertical rod 71 connected to the upper platen 611, a disengaging guide rod 72 connected to the lower mold 1 and located at the side of the linkage vertical rod 71, and a sectional ejection linkage assembly 73 connected to the lower platen 621, wherein the sectional ejection linkage assembly 73 comprises a mounting base 731 connected to the lower platen 621 and surrounding the linkage vertical rod 71 and the disengaging guide rod 72, a linkage slider 732 movably arranged in the mounting base 731 and facing the linkage vertical rod 71 and the disengaging guide rod 72, and a spring 733 arranged between the inner wall of the mounting base 731 and the linkage slider 732; a side groove 711 for the linkage slider 732 to be inserted is recessed on the side of the linkage vertical rod 71 facing the linkage slider 732, and a disengaging guide inclined surface 721 is formed on the side of the disengaging guide rod 72 facing the linkage slider 732, and a side sliding guide inclined surface 7321 matching the disengaging guide inclined surface 721 is formed on the end surface of the linkage slider 732 close to the disengaging guide rod 72.

[0048] When the disengaging driving rod 64 on the lower fixed plate 63 drives the upper platen 611 to move upward, the plurality of jacks 612 are driven by the upper platen 611 to move upward, so that the plastic part 20 is lifted upward by the plurality of jacks 612; at the same time, the upward movement of the upper platen 611 hooks the linkage slider 732 of the sectional ejection linkage assembly 73 upward through the side groove 711 of the linkage vertical rod 71, thereby driving the lower platen 621 to move upward synchronously, and driving the plurality of ejector pins 622 to move upward, so that the plastic part 20 is lifted upward by the plurality of ejector pins 622. When the lower platen 621 moves upward with the upper platen 611 by a stroke, the plastic part 20 is disengaged from the cavity 34; then, the side sliding guide inclined surface 7321 on the linkage slider 732 contacts the disengaging guide inclined surface 721 of the disengaging guide rod 72, and the linkage slider 732 is guided by the disengaging guide inclined surface 721 to move away from the linkage vertical rod 71, thereby compressing the spring 733 until the linkage slider 732 is disengaged from the side groove 711 of the linkage vertical rod 71, and then the lower platen 621 is disengaged from the upper platen 611, the upward movement of the lower platen 621 stops, and the lower platen 621, the plurality of ejector pins 622 and the sectional ejection linkage assembly 73 move downward synchronously to reset, and the linkage slider 732 is reset by the elastic restoring force of the spring 733; at the same time, the upper platen 611 continues to move upward, driving the tape 10 to continue to move upward, and the plastic part 20 combined with the tape 10 moves upward synchronously, so that the plastic part 20 is disengaged from the ejector pins 622, and finally the tape 10 and the plastic part 20 are disengaged from the lower mold 1, and the disengaging operation is completed.

[0049] By matching the sectional ejection mechanism 7 with the product demolding mechanism 6, sectional demolding operation is realized, and the synchronous demolding of the material belt 10 and the plastic part 20 is finally completed. The action of each structure is closely matched, each process is orderly, smooth, fast, stable and efficient, and the demolding efficiency is significantly improved; after demolding, the material belt 10 and the plastic part 20 are not damaged, and the product quality is guaranteed.

[0050] In order to position the material belt 10 and prevent it from moving to affect injection molding, a material belt positioning mechanism 8 is arranged on the lower mold 1, as shown in Figure 11 The material belt positioning mechanism 8 includes a plurality of positioning seats 81 arranged on the lower mold 1 and penetrating the second sliding block 32, at least one first material belt positioning needle 82 arranged in the positioning seat 81 and penetrating the upper end surface of the positioning seat 81, and at least one second material belt positioning needle 83 connected to the lower top plate 621 and penetrating the positioning seat 81, wherein a plurality of upper positioning clamping grooves 811 are formed on the upper end surface of the positioning seat 81, and a plurality of accommodation openings 321 are formed on the second sliding block 32 for the positioning seat 81 to penetrate, so that the positioning seat 81 is not affected when the second sliding block 32 slides, as shown in Figure 5 The positioning of the material belt 10 is realized by the combination of the plurality of positioning seats 81, the first material belt positioning needle 82 and the second material belt positioning needle 83.

[0051] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application.
