Description

Technical Field

[0001] This utility model relates to the field of therapeutic plate mold technology, specifically a mold for an acupoint massage device used in a myopia foot acupoint therapeutic plate. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In other words, molds are tools used to make shaped items. These tools are composed of various parts, and different types of molds are composed of different parts.

[0003] Product molds are specialized tools used for mass production of products. A product mold consists of massage blocks, acupoints, filling blocks, and a base plate. By stimulating acupoints and reflex zones on the soles of the feet and in areas related to myopia, it unblocks meridians, regulates internal organs, improves eye refractive accommodation, and helps prevent the development and progression of myopia.

[0004] This product is based on traditional Chinese medicine meridian and acupoint therapy. It is designed to treat myopia in children and adolescents by selecting acupoints according to syndrome differentiation. The product is placed in sports shoes and walked normally to massage and stimulate acupoints, thereby achieving the purpose of unblocking meridians, regulating internal organs, improving refractive accommodation, and preventing myopia.

[0005] The product consists of a positioning base plate, reflex zone massage blocks, reflex zone supplement blocks, and acupoints. The base plate of the combination plate is made of polyurethane and color powder (or color particles); the base plate of the fixing plate is made of modified silicone rubber and color powder (or color particles); the massage blocks, supplement blocks, and acupoints are made of modified silicone rubber and color powder (or color particles).

[0006] During production, materials (such as modified silicone rubber, nano antibacterial powder, far-infrared powder composite materials) are placed into a mold. Through heating, pressurization (such as injection molding, hot pressing) or pouring, the materials are formed and solidified in the mold cavity. Finally, the molded products are demolded to obtain instruments with consistent shapes that meet the design requirements.

[0007] Currently, there are generally two methods for manufacturing treatment panels: 3D printing and injection molding. 3D printing technology is mature and simple to operate, but it requires certain professional skills and is time-consuming for mass production. The process of changing between different models of treatment panels is cumbersome, and the printing materials are mostly nylon, EVA plastic, polyurethane foam, ABS plastic and other materials. These materials have high hardness, which makes the treatment panels less comfortable and not suitable for long-term use. Injection molding, on the other hand, is mostly a one-piece molding process, so the treatment panels produced are made of the same material. It is not possible to injection mold multiple sets of treatment panels with different materials on the same treatment panel. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example 1

[0023] like Figure 1-6As shown, the device includes two sets of template components for the left and right feet. Each template component consists of a bottom mold template, a partition template, and a top cover template that work together. The bottom mold template is first used in conjunction with the partition template through die casting or injection molding to initially form the upper layer of the acupoint treatment board 40. This bottom mold template can form various types of raised dots, which correspond to acupoints at different locations on the foot. During walking, the user can massage the acupoints on their feet through these raised dots. Then, the partition is removed, and the top cover template is used in conjunction with the bottom mold template to form the lower layer of the acupoint treatment board 40 through injection molding. This increases the thickness of the acupoint treatment board 40 at different locations, making it more closely fit the user's sole. Since different acupoints on the sole of the foot require different stimulation intensities, the thickness can be adjusted to regulate the distribution of the user's foot weight. For example, a thicker thickness at the heel shifts the overall center of gravity of the foot towards the toes, resulting in greater pressure on the toes. This is similar to how most of the body's force is concentrated at the toes when wearing high heels, thus adjusting the stimulation intensity of the raised dots on the treatment board.

[0024] The bottom mold template includes a left bottom mold base 10 and a right bottom mold base 11. Positioning protrusions are also provided on the left bottom mold base 10 and the right bottom mold base 11. A groove is provided inside the bottom mold template, and a foot model protrusion is provided in the groove. Several concave points and dividing ridges are provided on the foot model protrusion. The concave points are composed of three types: massage points, secondary acupoints, and primary acupoints. The concave points are set in areas by dividing ridges. The acupoints corresponding to each area can correspond to human organs. Stimulating the corresponding acupoints can achieve the purpose of treating the human organs. Since most users cannot confirm the location of the acupoints corresponding to the organs, it is difficult to select. However, the product produced in this application distinguishes each area, making it convenient for users to choose.

[0025] The left and right feet of the upper cover template are mirror symmetrical, both including an upper cover base 20. The upper cover base 20 is provided with a raised upper cover protrusion seat 201 and an upper cover positioning groove, which cooperate with the positioning protrusion to ensure the positioning accuracy between the two templates. An upper cover inner groove 202 is opened in the upper cover protrusion seat 201. Several upper cover protrusions 203 and protruding pillars are provided in the upper cover inner groove 202. The protruding pillars are located at the forefoot, and the protruding pillars can be used for ventilation at the forefoot.

[0026] The left and right feet of the partition template are mirror symmetrical and both include a partition base 30. The partition base 30 is provided with a raised partition protrusion seat 301 and a partition positioning groove. The partition protrusion seat 301 is provided with a partition inner groove 302. The partition inner groove 302 is provided with a multi-area partition block 303.

[0027] The left bottom mold base 10 has a left bottom mold groove 101 inside, which cooperates with the upper cover protrusion 201 to form a sealed space, which can form a treatment plate. The left bottom mold groove 101 contains a protruding left acupoint model 102. The left acupoint model 102 has several left massage points 1021, left secondary acupoints 1022, and left primary acupoints 1023. These points are all in the form of a combination of cylindrical and hemispherical grooves, with the radius of each point in the order: left massage point 1021 < left secondary acupoint 1022 < left primary acupoint 1023. Furthermore, the height of the left massage points 1021 is lower than that of the left secondary acupoints 1022 and left primary acupoints 1023, allowing the treatment plate to primarily utilize the left secondary acupoints 1022 and left primary acupoints 1023 to stimulate acupoints. The left massage points 1021 are distributed across the entire surface of the left acupoint model 102. Figure 2 As shown, the left auxiliary acupoint 1022 is distributed on the thumb, sole, and heel of the left point model 102, with a total of 12 acupoints. The left primary acupoint 1023 is distributed on the thumb and sole of the left point model 102, with a total of two acupoints. The approximate distribution is as follows: there are six left auxiliary acupoints 1022 and one left primary acupoint 1023 on the thumb; five left auxiliary acupoints 1022 and one left primary acupoint 1023 on the sole; and one left auxiliary acupoint 1022 on the heel.

[0028] The right bottom mold base 11 has a right bottom mold groove 111 inside, and a raised right point model 112 is set in the right bottom mold groove 111. The right point model 112 has several right massage points 1121, right secondary acupoints 1122, and right primary acupoints 1123, all of which are combinations of cylindrical and hemispherical grooves, and their radii are in the order of right massage point 1121 < right secondary acupoint 1122 < right primary acupoint 1123. Figure 3 As shown, the right massage point 1121 is distributed across the entire surface of the right point model 112. The right secondary acupoints 1122 are distributed on the thumb, sole, and heel of the right point model 112, totaling 14 acupoints. The left primary acupoints 1023 are distributed on the thumb and sole of the left point model 102, totaling three acupoints. They are roughly distributed as follows: five right secondary acupoints 1122 and one right primary acupoint 1123 on the thumb, six right secondary acupoints 1122 and two right primary acupoints 1123 on the sole, and three right secondary acupoints 1122 on the heel. By massaging different acupoints on the left and right feet, this mold product achieves the purpose of treating myopia. Example 2

[0029] like Figure 7 and Figure 8As shown, based on Example 1, the left auxiliary acupoints 1022 are distributed on the sole and heel, totaling 10 acupoints, and the left primary acupoints 1023 are distributed on the thumb, totaling one acupoint. The approximate distribution is one left primary acupoint 1023 on the thumb, six left auxiliary acupoints 1022 on the sole, and four left auxiliary acupoints 1022 on the heel.

[0030] The right secondary acupoint 1122 is distributed on the sole and heel, totaling 12 acupoints. The right primary acupoint 1123 is distributed on the big toe, totaling one acupoint. The approximate distribution is one right primary acupoint 1123 on the big toe, seven right secondary acupoints 1122 on the sole, and five right secondary acupoints 1122 on the heel. The acupoints of this mold product can help relieve myopia.

[0031] Therefore, in summary, the molds can be divided into children's sizes (shoe sizes) 31, 32, 33, 34; women's sizes 35, 36, 37, 38, 39, 40; and men's sizes 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, totaling 20 product molds. These molds can independently complete the production of products to specific specifications. Furthermore, each size mold can be designed with various types of mold plates based on the different therapeutic functions of acupoints, targeting the treatment of different diseases.

[0032] Therefore, this mold can be used to die-cast the preliminary shape of the protrusions of the treatment plate through the cooperation of the bottom mold template and the partition template. This is the manufacturing of the base plate of the product fixing plate, acupoints, massage blocks and filling blocks. The injection molding material here is modified silicone rubber and color powder. After the material here is initially cured, the protrusions, base plate and bottom mold template are kept unchanged. The partition template is removed and the upper cover template is used to cooperate with the bottom mold template to die-cast the overall thickness and final shape of the treatment plate, which is the base plate of the product's combination plate. The injection molding material here is polyurethane and color powder. After the product is completely cured, the product can be completely demolded. Therefore, according to the alternating cooperation of the three template components, multiple materials can be integrally injected into the same product to adapt to the material limitations of different positions of the product.

[0033] Working principle: During use, raw materials are injected into the bottom mold template through the control equipment on the production line. Then, the bottom mold template is first matched with the partition template to directly form the upper layer of the acupoint treatment board 40 through die casting, so that the treatment board has various types of protrusions, which correspond to acupoints at different locations on the feet. During the user's walking, the acupoints on the feet can be massaged through the protrusions. After the upper layer of the acupoint treatment board 40 has initially cooled and formed, the partition is removed, the top cover template is matched with the bottom mold template, and then another raw material is injected to form the lower layer of the acupoint treatment board 40, increasing the thickness of the acupoint treatment board 40 at different locations. The two layers are completely fused to form a complete treatment board, and finally, demolding is performed. Example 3

[0034] like Figure 9 and Figure 10 As shown, based on Embodiment 1, a counterweight plate 12 is slidably arranged inside the left bottom mold base 10. Several protrusion modules 13 are fixed on the counterweight plate 12. The sliding of the counterweight plate 12 will drive the protrusion modules 13 to slide together. The protrusion modules 13 replace the concave points of the secondary acupoints. That is, after the secondary acupoints are molded in Embodiment 1, their material is the same as that of the treatment plate base (the massage block, the supplementary block, the acupoints and the base of the fixing plate are made of the same material). By replacing the secondary acupoints with protrusion modules 13, the height of the protrusions at the secondary acupoints can be significantly higher than the other two types of protrusions. Moreover, their material is also different from the other two types of protrusions. The material here is a harder plastic and different colored particles than the other two types of protrusions. This makes it easier to distinguish the different positions of the protrusions. The harder and higher protrusions at the secondary acupoints will increase the stimulation of the acupoints and increase the effect of acupoint massage.

[0035] The bottom of the raised dot module 13 has at least two notches, and the top of the raised dot module 13 is fixed with a raised dot injection port 131. The raised dot injection port 131 is connected to an external injection molding equipment through a pipe. Different types of materials are injected into the raised dot module 13 through injection molding. Due to the poor adhesion between different materials, in order to increase the stability of the raised dots at the acupoints, the raised dot module 13 is designed to be elongated. During the die casting of the treatment plate, part of the raised dot module 13 will be completely inserted into the treatment plate, so that the molten material of the raised dot module 13 inside the treatment plate mixes with the molten fixing plate, and does not affect the material of the part of the raised dot module 13 outside the treatment plate. Therefore, it is ensured that the raised dot is completely fused with the treatment plate fixing plate to form a whole, and it is also ensured that the material of the raised dot generated by the raised dot module 13 is different from that of the other two types of raised dots. Nowadays, if it is necessary to increase the stability of the raised dot, it needs to be integrally molded with the treatment plate, but the material is the same at this time. If different materials are required, the raised dot is mostly cast separately and then glued to the treatment plate. This not only has a large workload, but the raised dot is also easy to fall off.

[0036] Working principle: Based on Example 1, raw material is injected into the bottom mold template. The bottom mold template and the partition template are first matched and die-cast. At this time, the bottom mold template needs to be on top, that is, the left bottom mold base 10 is on top. At this time, under the action of the weight of the counterweight plate 12, it will drive the protrusion module 13 into the molten raw material. Other materials are introduced into the protrusion module 13 through external injection molding equipment to squeeze out the raw material that entered the protrusion module 13 due to the die molding. This makes the part of the protrusion module 13 near the counterweight plate 12 contain only injection molding material, while the injection molding material and the die-casting raw material in the part away from the counterweight plate 12 can be fused together. Then, wait for cooling and perform preliminary solidification (incomplete solidification).

[0037] Then remove the partition template and inject another material into the top cover template to match the bottom mold template. At this time, the bottom mold template needs to be at the bottom, that is, the left bottom mold base 10 is at the bottom. At this time, the counterweight plate 12 will move the protrusion module 13 into the left bottom mold base 10 under its own weight. The molten material will fill the gap caused by the movement of the protrusion module 13, so that the protrusion module 13 is completely integrated into the two materials of the treatment plate, making it as an integral part of the treatment plate, which greatly increases its stability. In the case that the material of the protrusion produced by the protrusion module 13 is different from the material of other parts, it also avoids the problem of poor adhesion caused by different materials, which would cause the protrusion to fall off easily. After the treatment plate is completely cured, demolding can be performed.
