1. First, select the manufacturing mold for the corresponding shoe mold.
2. Close the upper and lower molds, melt the proportioned rubber sole and inject it into the sole mold.
3. Cool and shape, finish production and remove the completed injection mold.
4. Remove the outer cover of the mold after cooling.
5. Aim the solution spray gun toward the gap in the mold and pull the wrench along the path.
6. Remove the loose shoe mold from the mold.
7. Continue to use the solution spray gun to spray the space between the inner mold and the outer mold of the shoe mold, and pull the wrench along the trajectory.
8. Carefully separate the outer mold and inner mold with your hands.
9. The outer mold effect of the shoe mold is as shown below.
10. The internal casting effect of the shoe mold is as shown below.
11. Place the shoe mold into the mold engraving machine and set the data.
12. Wait for the machine to finely process the shoe mold.
13. The final completed shoe mold is as shown below.
Nature is the best teacher. Academician Yu Shuhong's team from the University of Science and Technology of China has developed an imitation lotus that can be used for surgical sutures. phenomenon of “broken and connected lotus roots”. Silk bacterial cellulose hydrogel fibers. This fiber suture has significant benefits in protecting damaged tissue, promoting wound healing, and reducing adverse effects.
Researchers used a detailed bionic spiral structure to give the material similar elasticitye to that of human skin. When the wound is deformed by force, BHF can effectively buffer and absorb energy, and achieve synchronous deformation with human tissues. avoids secondary injuries due to cuts. Compared with traditional cotton or polymer threads, hydrogel fiber sutures have the characteristics of high biocompatibility, high water content, low irritation and low friction resistance. They can protect damaged tissues, promote wound healing and reduce adverse reactions. , so it is expected to become the next generation of new high-end surgical sutures, laying a good foundation for its application in the field of high-end surgical sutures. In addition, the porous structure of the nanofiber hydrogel also allows BHF to absorb antibiotics or anti-inflammatory drugs, etc., andrelease them continuously at the wound level, thus playing an anti-inflammatory role and accelerating healing. Currently the corresponding patent. for this material has been reviewed and approved.
Besides creating bionic surgical sutures inspired by lotus roots, what other success stories do our scientists have? Flies and spaceships, a very peculiar little gas analyzer has been imitated from the boring fly. It was installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin. The leeward ears of jellyfish are modeled on the structure and function of jellyfish ears. Jellyfish Ear Storm Predictor is designed to predict storms 15 hours in advance, which is of great importance for the safety of shipping and fishing. Colorful butterflies are brilliant colors, such as double moon swallowtail, brown-veined monarch, etc., especiallyer the fluorescent-winged swallowtail, whose wings sometimes turn gold, sometimes emerald green, and sometimes change from purple to blue in the Scientists have studied sunlight. The study of butterfly colors has brought great benefits to military defense. After it was proposed to use the colors of butterflies to make them less conspicuous among flowers, military installations were covered with camouflage resembling butterflies . Therefore, based on the same principle, camouflage uniforms were later produced.
