Description

Technical Field

[0001] This utility model relates to the field of microneedle mold technology, specifically a magnetic microneedle positioning and forming mold. Background Technology

[0002] Microneedle molds are tools or devices used to manufacture microneedle arrays, widely used in the biomedical field, such as drug delivery, skin care, and medical diagnostics. Microneedles are miniaturized needles, only tens of micrometers to a few millimeters in length, capable of easily penetrating the skin's surface without touching nerve endings, resulting in virtually painless use. The design and fabrication of the microneedle mold are crucial to the quality of the microneedles. Manufacturing involves filling the mold with the selected microneedle material, such as a soluble polymer or metal, then curing it through heating or ultraviolet light. Finally, the microneedle array can be easily removed, completing the fabrication process.

[0003] For example, patent CN209478729U discloses a microneedle mold and a mold itself. This microneedle mold has a microneedle forming hole and a drainage channel. One end of the drainage channel is connected to the microneedle forming hole, and the other end is connected to a negative pressure generator. Through this connection, during the microneedle forming process, the negative pressure generator can apply negative pressure to the drainage channel, allowing any air bubbles that may be generated in the microneedle to escape through the drainage channel, preventing air bubble residue in the microneedle, and ensuring that the microneedle preparation liquid smoothly fills the microneedle forming hole. The microneedle mold has a simple structure, is easy to operate, highly efficient, and has low operating costs.

[0004] The aforementioned microneedle mold still has certain defects:

[0005] Because the microneedles produced by current microneedle molds are extremely small, with delicate structures and subtle dimensions, the adhesion between the microneedles and the mold surface is greater, making it more difficult to demold the microneedles and hindering production efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a magnetic microneedle positioning molding die, making demolding simpler and more convenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetic microneedle positioning and forming mold, including a lower mold, a support plate installed on the top of the lower mold, grooves provided on both sides inside the support plate, an upper mold installed on the top of the support plate, ejection components fixedly connected to both ends of both sides of the support plate, and fixing components slidably connected to both ends of both sides of the upper mold.

[0008] Furthermore, the ejection assembly includes a support rod and an elastic element. Both ends of the lower mold and the upper mold are provided with receiving grooves. The support rod is slidably connected inside the receiving groove. The end of the support rod away from the support plate is fixedly connected to the elastic element, and the other end of the elastic element is fixedly connected to the end of the receiving groove.

[0009] Furthermore, the cross-section of the support rod is T-shaped.

[0010] Furthermore, the fixing component includes a slider and a fixing plate. Slide grooves are provided at both ends of the top sides of the upper mold. A slider is slidably connected inside the slide groove, and a fixing plate is fixedly connected to the top of the slider.

[0011] Furthermore, a magnetic block is fixed to the lower end of the fixing plate near the lower mold, and the magnetic block attracts the lower mold.

[0012] Furthermore, the end of the slider is trapezoidal.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] After production is completed, the fixing component of this magnetic microneedle positioning molding die can be opened. Under the action of the ejection component, the upper die and the tray will move upward by themselves, thereby lifting the finished product from the lower die so that the finished product can be taken out.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 A magnetic microneedle positioning and forming mold includes a lower mold 1, a support plate 2 installed on the top of the lower mold 1, grooves 4 on both sides inside the support plate 2, an upper mold 3 installed on the top of the support plate 2, ejection components fixedly connected to both ends of both sides of the support plate 2, and fixing components slidably connected to both ends of both sides of the upper mold 3.

[0022] In this utility model, the magnetic microneedle positioning and forming mold can open the fixing component after the microneedles have solidified. Under the action of the ejection component, the upper mold 3 and the support plate 2 will move upward on their own. Since the support plate 2 has grooves 4 on both sides, part of the microneedles will be in the grooves 4. When the support plate 2 moves upward, it will lift the microneedles from the lower mold 1, so that the production personnel can take out the finished product. In addition, the structure of the lower mold 1 in this utility model is similar to a microneedle mold and mold structure disclosed in the patent with patent authorization announcement number CN209478729U, so it will not be described in detail here.

[0023] like Figures 1 to 4 As shown, the ejection assembly includes a support rod 6 and an elastic element 7. Both ends of the lower mold 1 and the upper mold 3 are provided with a receiving groove 5. The support rod 6 is slidably connected inside the receiving groove 5. The end of the support rod 6 away from the support plate 2 is fixedly connected to the elastic element 7, and the other end of the elastic element 7 is fixedly connected to the end of the receiving groove 5.

[0024] Specifically, after the fixing component is opened, the elastic element 7 will unfold on its own without being restricted, thereby pushing the tray 2 and the upper mold 3 upward, so that the tray 2 and the upper mold 3 can be moved upward, making it easier for the operator to take out the finished product.

[0025] like Figure 3 As shown, the support rod 6 has a T-shaped cross-section. The T-shaped support rod 6 is less likely to detach from the storage groove 5.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing component includes a slider 9 and a fixing plate 10. Both ends of the top sides of the upper mold 3 are provided with grooves 8. The slider 9 is slidably connected inside the grooves 8, and the fixing plate 10 is fixedly connected to the top of the slider 9.

[0027] Specifically, after the lower mold 1, the support plate 2 and the upper mold 3 are closed, the slider 9 on the fixing plate 10 can be aligned with the slide groove 8, and then the slider 9 can be inserted into the slide groove 8, thereby fixing the lower mold 1, the support plate 2 and the upper mold 3 through the fixing plate 10 to prevent the support plate 2 and the upper mold 3 from unfolding on their own.

[0028] like Figure 4 As shown, a magnetic block 11 is fixed to the lower end of the fixed plate 10 near the lower mold 1, and the magnetic block 11 and the lower mold 1 attract each other.

[0029] Specifically, after the slider 9 is fully inserted into the groove 8, the magnetic block 11 on the fixing plate 10 will attract each other to the lower mold 1, thereby fixing the fixing plate 10 and preventing the fixing plate 10 from detaching from the lower mold 1.

[0030] like Figure 4 As shown, the end of slider 9 is trapezoidal. The trapezoidal slider 9 is not easily disengaged from above the groove 8.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
