[0035] Embodiment 1

[0036] Refer to Figures 1 to 5, this embodiment mentions a slider structure, including a slider insert 11. The slider insert 11 is located between the upper die core 2 and the lower die core 3. After the mold is closed, the slider insert 11, the upper die core 2 and the lower die core 3 can be combined together to jointly enclose and form a molding cavity for the hair clipper blade 4. The molding cavity matches the overall shape of the hair clipper blade 4. The front end of the hair clipper blade 4 is arc-shaped. At the corresponding position of the front end of the hair clipper blade 4 on the slider insert 11, a first molding part 111 matching the shape of the front end of the hair clipper blade 4 is provided. The molding shape of the front end of the hair clipper blade 4 is controlled by the first molding part 111 to form a fully enclosed molding, changing the position of the mold closing line and moving the mold closing line down to other parts, so that there is no longer any flash on the product, improving work efficiency. At the same time, there is no flash on the mold, reducing the number of repairs and extending the service life of the mold. Again, when there is a problem with the tooth-shaped surface of the mold, it can be solved by directly replacing the slider insert or the slider structure without worrying about the problem of repeated precision.

[0037] Embodiment 2

[0038] On the basis of the above embodiments, as an optional implementation manner, the slider structure further includes a slider body 12 and a slider cam 13. The slider body 12 is connected to the slider insert 11. The connection here is preferably a bolt connection, which is convenient for disassembly and assembly. When the slider insert 11 reaches its service life or its structure is damaged, it is easier to replace the slider insert 11 separately, saving costs. A cam groove 121 is formed on the slider body 12, and the slider cam 13 is inserted into the cam groove 121. The slider cam 13 and the cam groove 121 cooperate with each other. According to the basic principle of the cam structure, when the slider cam 13 moves relative to the cam groove 121, it can drive the slider body 12 to move in different directions, with a higher degree of automation. Specifically, when the slider cam 13 moves downward under the action of an external force, it can drive the slider body 12 to move toward the upper die core 2 and the lower die core 3. A spring-back structure 122 is provided on the slider body 12. When the external force on the slider cam 13 is removed and it moves upward, the spring-back structure 122 is activated to drive the slider body 12 to move away from the upper die core 2 and the lower die core 3. Thus, by the movement of the slider cam 13, the slider body 12 and the slider insert 11 can move relatively closer to or away from the upper die core 2 and the lower die core 3. Since the first forming portion 111 on the slider insert 11 can control the forming shape of the front end of the hair clipper blade 4 and form a state of wrapping the front end of the hair clipper blade 4, it also has a certain limiting function to limit the formed hair clipper blade 4. Therefore, before forming, the slider insert 11 is moved relatively closer to the upper die core 2 and the lower die core 3, so that the upper die core 2, the lower die core 3, and the slider insert 11 form the above-mentioned forming cavity to form the hair clipper blade 4. After forming, the slider insert 11 is moved relatively away from the upper die core 2 and the lower die core 3, so that the part of the slider insert 11 wrapping the front end of the hair clipper blade 4 is unwrapped, and at the same time, it is equivalent to removing the limit on the front end of the hair clipper blade 4, facilitating its removal.

[0039] Embodiment III

[0040] On the basis of the above embodiments, as an alternative implementation, the resilient structure 122 includes a movable slot 1221 and a spring 1222. A movable slot 1221 is formed on the slider body 12. The number of movable slots 1221 is at least one. One end of each spring 1222 is connected to one movable slot 1221. In the mold-closed state, the slider body 12 abuts against the upper mold core 2. Therefore, the other end of the spring 1222 is located outside the movable slot 1221 in the natural state and abuts against the upper mold core 2. In the mold-closed state, the spring 1222 is compressed. In the mold-open state, the spring 1222 resets, driving the slider body 12 to move away from the upper mold core 2 and the lower mold core 3. The spring 1222 has good elasticity, which is beneficial to the resilience of the slider body 12. In this embodiment, the number of movable slots 1221 is preferably two. Therefore, the number of springs 1222 is also two, and they are symmetrically arranged to balance the force.

[0041] Embodiment Four

[0042] On the basis of the above embodiments, as an alternative implementation, the slider cam 13 includes a vertical portion 131 and an inclined portion 132 which are integrally connected. The inclined portion 132 is inserted into the cam slot 121. The slope of the inclined portion 132 is the same as the slope of the cam slot 121. The moving directions of the slider body 12 and the slider insert 11 are perpendicular to the length direction of the vertical portion 131. And with the inclined portion 132 and the cam slot 121 having the same slope, when the inclined portion 132 moves relative to the cam slot 121, it can drive the slider body 12 and the slider insert 11 to move in a direction perpendicular to the moving direction of the slider body 12, realizing the movement of the slider body 12 and the slider insert 11 in a limited space, and better reducing the volume of the device and saving space.

[0043] Embodiment Five

[0044] On the basis of the above embodiments, as an alternative implementation, the outer surface of the first molding portion 111 is continuous and has a smooth transition. The continuous and smooth outer surface can ensure the formed shape at the front end of the hair clipper blade 4, change the position of the original mold joint line, move the mold joint line down to other parts, so that no flash is generated on the product.

[0045] Embodiment Six

[0046] Based on the above embodiments, as an alternative implementation, a second forming portion 112 continuous with the first forming portion 111 is provided at the lower part of the slider insert 11. The first forming portion 111 is mainly used for forming the front end of the hair clipper blade 4, and the second forming portion 112 is mainly used for forming the top surface of the hair clipper blade 4. The continuity of the first forming portion 111 and the second forming portion 112 enables a natural transition between the top surface and the front end of the hair clipper blade 4. A third forming portion 21 is provided at the lower part of the upper die core 2. The third forming portion 21 is also used for forming the top surface of the hair clipper blade 4, but only responsible for forming a small part of it. It cooperates with the second forming portion 112 to form the complete top surface of the hair clipper blade 4. A fourth forming portion 31 is provided at the upper part of the lower die core 3. The fourth forming portion 31 is mainly used for forming the bottom surface of the hair clipper blade 4. The first forming portion 111, the second forming portion 112, the third forming portion 21, and the fourth forming portion 31 enclose a forming cavity for the hair clipper blade 4, which is beneficial for injecting raw materials into the forming cavity later, and injection molding is carried out under the cooperation of the first forming portion 111, the second forming portion 112, the third forming portion 21, and the fourth forming portion 31.

[0047] Embodiment Seven

[0048] Referring to Figures 1 to 7 , this embodiment also mentions a forming mold for a hair clipper blade, including an upper die core 2, a lower die core 3, and the above-mentioned slider structure. The slider structure includes a slider insert 11. The slider insert 11 is located between the upper die core 2 and the lower die core 3. The slider insert 11, the upper die core 2, and the lower die core 3 can be combined together after mold closing to jointly enclose a forming cavity for the hair clipper blade 4. The forming cavity matches the overall shape of the hair clipper blade 4. The front end of the hair clipper blade 4 is arc-shaped. A first forming portion 111 matching the shape of the front end of the hair clipper blade 4 is provided at the corresponding position of the slider insert 11 at the front end of the hair clipper blade 4. The forming shape of the front end of the hair clipper blade 4 is controlled by the first forming portion 111 to form a fully enclosed forming, changing the position of the mold closing line and moving the mold closing line to other areas, so that there is no longer any flash on the product, improving work efficiency. At the same time, there is no flash on the mold, reducing the number of repairs and extending the service life of the mold. Again, when there is a problem with the tooth-shaped surface of the mold, it can be solved by directly replacing the slider structure without worrying about the problem of repeated precision.

[0049] Embodiment Eight

[0050] Based on the above embodiments, as an alternative implementation, it further includes an upper die body 5 and a lower die body 6. An upper die core 2 is arranged inside the upper die body 5, and a lower die core 3 is arranged inside the lower die body 6. A sliding groove 7 is jointly opened between the upper die body 5 and the lower die body 6. The size of the sliding groove 7 matches the cross-sectional size of the slider body 12 along its length direction. The sliding groove 7 provides a specific sliding space for the slider body 12 and the slider insert 11 and determines the moving direction. The slider body 12 can slide in the sliding groove 7 to drive the slider insert 11 to move simultaneously. At the same time, a set of heating devices are respectively arranged on the upper die body 5 and the lower die body 6 to ensure the temperature of the upper die body 5 and the lower die body 6 when the dies are closed. In addition, a feeding structure is arranged on the upper die body 5, and raw materials are injected into the synthesis cavity through the feeding structure for synthesis. The heating device and the feeding structure are both relatively conventional existing technologies, so no specific expansion will be made here.

[0051] Embodiment Nine

[0052] Based on the above embodiments, as an alternative implementation, the upper die body 5 is respectively provided with a set of first limiting parts 51 on both sides of the sliding groove 7. The first limiting parts 51 are detachably connected to the upper die body 5, and the installation of the slider structure can be realized by disassembling and assembling the first limiting parts 51, which is beneficial to the replacement of the slider structure. Therefore, when the first limiting parts 51 are installed on the upper die body 5, the first limiting parts 51 can prevent the slider body 12 from separating from the upper die body 5 in the vertical direction. Here, the vertical direction refers to the direction perpendicular to the moving direction of the slider body 12 itself.

[0053] Embodiment Ten

[0054] Based on the above embodiments, as an alternative implementation, a set of second limiting parts 52 are arranged on the upper die body 5. The second limiting parts 52 can prevent the slider body 12 from separating from the sliding groove 7 in the horizontal direction. Here, the horizontal direction refers to the moving direction of the slider body 12 itself. The second limiting parts 52 are preferably a bolt, which is bolted to the upper die body 5 and is located in the moving direction of the slider body 12. When the slider body 12 moves to the extreme position farthest from the upper die core 2 and the lower die core 3, it can be blocked by the bolt of the second limiting part 52, so that the slider body 12 does not separate from the sliding groove 7.

[0055] The above are only the specific implementation manners of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
