Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a processing mold for a bionic muscle prosthesis. Background Art

[0002] Most of the female adult products on the market use the method of installing a vibration motor inside the humanoid sexual organ muscles to make the humanoid sexual organ muscles produce periodic vibrations. Since the motor is a linear motor, it realizes the imitation of artificial muscles through linear motion. Therefore, the silicone rubber attached to the outside of the rotary to linear mechanism becomes thinner on a macro scale during movement and cannot become thicker. It can only move and stop (stall). The shape of the humanoid sexual organ muscles is fixed and cannot meet the user's needs for different shapes. In addition, the vibration and amplitude caused by the rotation of the motor are very small, and the noise generated is also loud, so the experience of this type of product is not good.

[0003] In the prior art, in theory, a bionic muscle prosthesis with a permanent magnet can be driven by an electromagnet to simulate the expansion and contraction of muscles and different forms of movement to meet more needs of users and solve noise problems. However, to prepare such a bionic muscle prosthesis with a permanent magnet, the permanent magnet needs to be placed in a mold and molded together with the injection molding material. However, on the one hand, the high temperature during molding may cause the permanent magnet to heat up and demagnetize. On the other hand, the pressure during injection molding may also cause the permanent magnet to shift in the mold. Therefore, it is difficult to ensure the magnetic properties of the permanent magnet in the processed product and to fix the permanent magnet in the required position. Summary of the invention

[0031] DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] The present invention proposes a processing mold 100 for a bionic muscle prosthesis 510, which aims to achieve normal filling of the permanent magnet 512 in the bionic muscle prosthesis 510 and avoid random displacement of the permanent magnet 512 in the mold due to heating and demagnetization when the permanent magnet 512 is molded together with the injection molded part and pressure during injection molding.

[0035] See also Figures 1 to 4 In one embodiment of the present invention, a processing mold 100 for a bionic muscle prosthesis 510 is provided, comprising: a mold base 110, a mold core 130 and a plurality of core rods 150; the mold base 110 is formed with a mold cavity 110a, the mold core 130 is arranged in the mold cavity 110a, the plurality of core rods 150 are respectively extended along the length direction of the mold core 130, and are circumferentially arranged in the mold cavity 110a around the mold core 130, and the mold base 110 is provided with an injection port 110b connected to the mold cavity 110a, which is used to inject injection plastic into the mold cavity 110a, so as to form a hollow bionic muscle prosthesis body 511 with a plurality of through holes 511a.

[0036] It should be noted that a cavity 110a is formed inside the mold base 110 for containing injection molding material, and the mold core 130 is placed in the cavity 110a so that the bionic muscle prosthesis 510 is hollow during molding, that is, there is a cavity in the middle that runs through the bionic muscle prosthesis body 511. A plurality of core rods 150 are extended along the length direction of the core mold 330 and arranged in the cavity 110a, that is, the direction of the core rods 150 is consistent with the direction of the core 130. At the same time, the core rods 150 are arranged in the cavity 110a around the circumference of the core 130, so that the bionic muscle prosthesis body 511 has a plurality of through holes 511a surrounding the cavity during molding, which are used to insert the permanent magnet 512, and the mold base 110 is provided with an injection port 110b connected to the cavity 110a for injecting the injection molding material. Specifically, the mold base 110 can be a single mold formed in one piece, or it can be a mold base 110 composed of multiple molds spliced ​​together. The mold core 130 and the core rod 150 can be inserted into the mold cavity 110a by opening an installation channel on the mold base 110, or the mold core 130 and the core rod 150 can be set on the inner wall of one side of the mold base 110, and an opening can be set on the other side to facilitate product demolding; at the same time, the spacing, size and number between the multiple core rods 150 can be adjusted according to the specific situation, the present invention is not limited to this, and the above methods are all within the protection scope of the present invention.

[0037] See also Figures 1 to 4 In one embodiment of the present invention, the mold base 110 has two adjacent surfaces, one of which is formed with a mold cavity 110a connected to the outside, and the other is formed with an injection port 110b, which is arranged above the mold cavity 110a. It should be noted that, among any two adjacent surfaces of the mold base 110, one of which is formed with a mold cavity 110a connected to the outside, and the other is formed with an injection port 110b connected to the mold cavity 110a, and the injection port 110b is located above the mold cavity 110a, so that the injection plastic can naturally flow into the mold cavity 110a during injection. Figures 1 to 4 In one embodiment of the present invention, a surface of the mold base 110 having the mold cavity 110a is provided with a plurality of assembly channels, the assembly channels penetrate the mold cavity 110a, and the plurality of core rods 150 are respectively installed in the mold cavity 110a through the plurality of assembly channels.

[0038] It should be noted that a plurality of assembly channels are also formed on the surface forming the mold cavity 110a, and the assembly channels are used to insert a plurality of core rods 150. The specific arrangement of the assembly channels corresponds to the mold core 130 and the plurality of core rods 150. While the assembly channel is interconnected with the mold cavity 110a, the assembly channel also runs through the mold cavity 110a, that is, a groove is formed on the inner wall of the mold cavity 110a opposite to the surface forming the assembly channel, and one end of the core rod 150 is placed inside the groove, which can prevent the pressure during injection molding from causing the core rod 150 to move inside the mold cavity 110a and cause deformation of the finished product.

[0039] See also Figures 1 to 4 In one embodiment of the present invention, the mold base 110 includes two templates arranged opposite to each other, and the surfaces of the two templates opposite to each other are concave to form a mold cavity 110a, and the two templates are movably connected to open or close the mold cavity 110a. It should be noted that the mold base 110 includes two templates arranged opposite to each other, and the surfaces of the two templates opposite to each other are respectively formed with a cavity. When the two templates are connected, the mold base 110 is formed, and the cavities formed by each are connected to each other to form the mold cavity 110a. When the two templates are connected, the mold cavity 110a is closed, and after molding, the two templates are opened to allow the product to be demolded. In this embodiment, an upper template 111 and a lower template 112 are provided, and an upper mold cavity 110a is formed on the bottom surface of the upper template 111, and an upper mold cavity 110a is formed on the top surface of the lower template 112. When the upper template 111 and the lower template 112 are pressed together, the upper mold cavity 110a and the lower mold cavity 110a are connected to form the mold cavity 110a; specifically, the two relative templates may be left and right templates, and the shapes of the two templates and the mold cavities 110a formed by each of them may also be different, which can be adjusted according to specific circumstances. The present invention is not limited to this, and the above methods are all within the protection scope of the present invention.

[0040] See also Figures 1 to 4 In one embodiment of the present invention, the template has two ends facing each other, one end of the two templates fits each other, and the other ends of the two templates are provided with a gap, so as to form a mold cavity 110a connected to the outside, and the mold core 130 is inserted in the mold cavity 110a. It should be noted that the two ends of the template facing each other refer to the two ends forming part of the surface of the mold cavity 110a. Taking the upper template 111 formed with the upper mold cavity 110a as an example, the two ends facing each other refer to the left and right ends of the upper template 111; in this embodiment, a notch is provided on the left side of the upper and lower templates 112. When pressed together, the right ends of the upper and lower templates fit each other, and the left ends cannot fit due to the notch, so as to achieve the effect of the gap setting, and the mold core 130 is inserted into the mold cavity 110a through the gap formed by the notch on the left side of the upper and lower templates 112. Specifically, the two ends facing each other will change according to the specific orientation of the template forming the mold base 110. When the left and right templates form the mold base 110, the upper and lower ends of the template become the two ends facing each other. Adjustments can be made according to specific circumstances, and the present invention is not limited thereto. The above methods are all within the scope of protection of the present invention.

[0041] See also Figures 1 to 4The present invention also provides a processing method of a bionic muscle prosthesis 510 using a processing mold 100 for a bionic muscle prosthesis 510, comprising the following steps: S110, closing the processing mold 100 of the bionic muscle prosthesis 510, injecting injection plastic into the injection port 110b, and molding and demolding to obtain a bionic muscle prosthesis body 511 with a hollow cavity 511b and a plurality of through holes 511a; S120, respectively inserting a plurality of permanent magnets 512 into the plurality of through holes 511a to obtain the bionic muscle prosthesis 510. It should be noted that the bionic muscle prosthesis 510 is a corresponding product of the processing mold 100 of the bionic muscle prosthesis 510. The specific manufacturing process is that after the upper and lower molds of the bionic muscle prosthesis 510 are molded, the injection plastic is injected into the processing mold 100 of the bionic muscle prosthesis 510 along the injection port 110b of the upper template 111 of the processing mold 100 of the bionic muscle prosthesis 510. The injection plastic can be a thermoplastic elastomer, solid silicone rubber, liquid silicone rubber, etc., and the corresponding molding method is also different according to the difference of the injected injection plastic. During molding, due to the restriction of the mold core 130 and a plurality of core rods 150 on the injection plastic, the bionic muscle prosthesis body 511 after demoulding molding will have a hollow cavity 511b and a plurality of through holes 511a that penetrate itself, and a plurality of permanent magnets 512 are respectively filled in the through holes 511a around the hollow cavity 511b, so that the bionic muscle prosthesis 510 can be obtained. The hollow cavity 511b is used for inserting the electromagnet 700 and cooperating with the permanent magnet 512 to control the expansion and contraction of the bionic muscle prosthesis 510, so as to simulate the movement of the muscle. Regarding the specific shape of the permanent magnet 512, a fan-shaped columnar permanent magnet 512 is used in this embodiment. Permanent magnets 512 of different shapes such as discs, rings, rectangles, squares and polygons can be selected according to actual conditions. The present invention is not limited to this, and the above are all within the protection scope of the present invention.

[0042] See also Figures 1 to 4The present invention also provides a method for manufacturing a composite bionic muscle prosthesis 500 applied to a mold set, comprising the following steps: S210, closing the processing mold 100, injecting injection plastic into the injection port 110b of the processing mold 100, performing injection molding, and demolding to obtain a hollow bionic muscle prosthesis body 511 with multiple through holes 511a; S220, sequentially inserting multiple permanent magnets 512 into the multiple through holes 511a of the bionic muscle prosthesis body 511, to obtain To the bionic muscle prosthesis 510; S230, multiple bionic muscle prostheses 510 are sequentially mounted on the core mold 330 of the core mold 300, the core mold 300 includes a bottom mold 350, a core mold 330 and a top mold 310, so that multiple bionic muscle prostheses 510 are arranged along its length; S240, injection molding is injected into the core mold 300 and vulcanized to form multiple bionic muscle prostheses 510 into an integrated structure, and a composite bionic muscle prosthesis 500 is obtained after demolding. It should be noted that in this method, the bionic muscle prosthesis 510 needs to be made first, and when the mold is used for making, the specific making method is the same as above, and no further description is given here. In some embodiments, the method for making the bionic muscle prosthesis 510 is to first make a strip or sheet bionic muscle prosthesis body 511, then place a plurality of permanent magnets 512 in one direction, cover another layer of bionic muscle prosthesis body 511 on the permanent magnets 512, and after gluing, curl the bionic muscle prosthesis 510 with permanent magnetic material sandwiched between the two layers of silicone rubber after molding into a tubular shape, and bond the interface, so as to make the bionic muscle prosthesis 510. In step S230, a plurality of bionic muscle prostheses 510 are first made, and the bionic muscle is sequentially sleeved on the core mold 330 through the hollow cavity 511b of the bionic muscle prosthesis 510. Different bionic muscle prostheses 510 can be connected or spaced from each other, and corresponding changes can be made according to specific needs, and the present embodiment is not limited thereto. The core mold 330 with the bionic muscle prosthesis 510 is placed between the top mold 310 and the bottom mold 350, and the top mold 310, the bottom mold 350, and the core mold 330 of the core mold 300 are molded together. The injection plastic consistent with the bionic muscle prosthesis 510 is injected into the top mold 310 of the core mold 300, so that the injection plastics molded twice can be better integrated together. Since the permanent magnet 512 is wrapped by the bionic muscle prosthesis 510, the bionic muscle prosthesis 510 has the support of the core mold 330, so when the core mold 300 is molded, the injected injection plastic will not cause the permanent magnet 512 to move due to the pressure generated during its own flow. At the same time, the permanent magnet 512 does not directly contact the injected injection plastic, and the bionic muscle prosthesis 510 has a certain heat insulation function. Therefore, even if the injection plastic that requires high temperature molding is injected, the permanent magnet 512 will not be demagnetized due to temperature rise during the molding process.After molding, demolding is performed to obtain a composite bionic muscle prosthesis 500, in which multiple bionic muscle prostheses 510 are composited. Compared with a single bionic muscle prosthesis 510, the composite bionic muscle prosthesis 510 has multiple different segments of permanent magnets 512 in the same direction. It can be understood that the control of the composite bionic muscle prosthesis 500 using the electromagnet 700 is more refined than that of a single bionic muscle prosthesis 510.

[0043] For details, see Figure 4 In this embodiment, a bionic muscle device is provided, which is processed using the above-mentioned bionic muscle prosthesis processing method or the composite bionic muscle prosthesis processing method, including: a composite bionic muscle prosthesis body that is formed into one piece with the injection molding material after multiple bionic muscle prosthesis bodies 511 undergo step S240, and does not contain a permanent magnet. The composite bionic muscle prosthesis body is an elastic columnar structure, and the end surface of the composite bionic muscle prosthesis body is recessed to form a receiving cavity; a permanent magnet 512, which is built into the cavity wall of the receiving cavity; an electromagnet 700, which is arranged in the receiving cavity; and a power supply module, which is electrically connected to the electromagnet 700. When powered on, the electromagnet 700 is magnetized to attract or repel the permanent magnet 512 to drive the composite bionic muscle prosthesis body to undergo elastic deformation. In this embodiment, the electromagnet 700 arranged in the accommodating cavity of the composite bionic muscle prosthesis body can attract and repel the permanent magnet 512 in the cavity wall when energized, thereby driving the composite bionic muscle prosthesis body to deform and move, stimulate the female reproductive organs, and meet the user's needs for prostheses of different shapes. In addition, this embodiment does not have the mechanical movement mechanism of traditional adult toys, which can reduce the noise generated when the mechanical mechanism of traditional adult toys is used.

[0044] In the present embodiment, the materials used to manufacture the composite bionic muscle prosthesis body include but are not limited to polymer materials, silicone and other thermosetting materials. The thermosetting materials can maintain high elastic deformation properties after thermal curing, and the thermosetting materials are also skin-friendly and not prone to allergies. The composite bionic muscle prosthesis body is hollow inside to form a accommodating cavity, and the outside is based on a columnar structure. The specific shapes of the outside include: cylinders, polygonal prisms, polygonal rounded prisms, curved columnar structures, male genital columnar structures and other special-shaped columnar structures. The composite bionic muscle prosthesis body does not strictly use the above shapes, but is improved on the basis of the above shapes to be more suitable for the appearance of female genitals. Optionally, a spherical end is expanded at the closed end of the composite bionic muscle prosthesis body. The electromagnet 700 is installed on a package, and the package has a through hole. The power supply module is electrically connected to the electromagnet through the through hole. The electromagnet 700 is placed as a whole in the accommodating cavity of the composite bionic muscle prosthesis body. The closed end of the composite bionic muscle prosthesis body is detachably connected to the package. The shape of the electromagnet 700 is determined according to the magnetization effect that can be achieved. The magnetization direction of the electromagnet 700 can be set according to actual needs, and a permanent magnet 512 is set in the cavity wall of the composite bionic muscle prosthesis body. When the power is on, the electromagnet 700 magnetizes to attract or repel the permanent magnet 512 in the cavity wall, driving the cavity wall to deform. Different magnetization directions and their corresponding permanent magnets enable the composite bionic muscle prosthesis body to obtain various shape deformations, meeting the user's needs for various shape deformations. Specifically, the electromagnet 700 has different magnetization directions by means of magnetization heads having multiple directions, the magnetization heads are rigidly connected to each other, or a positioning tube is arranged on the central axis of the composite bionic muscle prosthesis body, and the magnetization head is sleeved on the positioning tube, such as the magnetization head of the magnetization direction is arranged along the length direction of the composite bionic muscle prosthesis body, the magnetization head of the magnetization direction is arranged along the radial direction of the composite bionic muscle prosthesis body, or the magnetization head of the magnetization direction is arranged along a direction at a certain angle to the axis of the composite bionic muscle prosthesis body, and The permanent magnet 512 is arranged in the magnetization influence area of ​​these magnetization heads, and the permanent magnet 512 can deviate from the magnetization direction of the electromagnet 700, so that when the power is on, the permanent magnet 512 is attracted or repelled by the magnetization of the electromagnet 700 to drive the composite bionic muscle prosthesis body to bend and deform; the permanent magnet 512 can also be arranged in the magnetization direction of the electromagnet 700, so that when the power is on, the permanent magnet 512 is attracted or repelled by the magnetization of the electromagnet 700 to drive the composite bionic muscle prosthesis body to linearly deform. Of course, the embodiment of the present invention can adjust the spacing distance between the permanent magnet 512 and the electromagnet 700 so that the permanent magnet 512 is in the magnetization radiation area of ​​the electromagnet 700, thereby realizing the driving of the composite bionic muscle prosthesis body.In addition, the embodiment of the present invention can also be provided with a plurality of permanent magnets 512, and the plurality of permanent magnets 512 are respectively arranged in the magnetization direction of the electromagnet 700 or deviate from the magnetization direction of the electromagnet 700, so as to drive the composite bionic muscle prosthesis body to undergo linear deformation and bending deformation at the same time. The shape of the permanent magnet 512 in the embodiment of the present invention includes but is not limited to: rectangular, polygonal, circular, elliptical, irregular cake / sheet, and the thickness of the permanent magnet 512 does not exceed the thickness of the cavity wall of the composite bionic muscle prosthesis body, and can be covered by the cavity wall of the composite bionic muscle prosthesis body. The power supply module includes a DC power supply, an AC power supply or a DC-AC hybrid power supply, which enables the bionic muscle device 100 to be portable and use a charging power supply, or to be used in an AC plug-in mode, and can also have two modes at the same time. The electrical connection between the power supply module and the electromagnet 700 is a combination connection mode of all parallel or all series or partly series and partly parallel, which enables the power supply module to accurately control whether the magnetization head on the electromagnet 700 is magnetized, and then control the composite bionic muscle prosthesis body to undergo different shape deformation. The embodiments of the present invention are not limited thereto, and all of the above are within the protection scope of the embodiments of the present invention.

[0045] See also Figures 1 to 4 In one embodiment of the present invention, in the step of "sleeving a plurality of bionic muscle prostheses 510 in sequence on the core mold 330 of the core mold 300", the core mold 300 includes a bottom mold 350, a core mold 330 and a top mold 310, a molding cavity is provided between the bottom mold 350 and the top mold 310, the core mold 330 is provided in the molding cavity, and the top mold 310 is provided with a material injection port 310a connected to the molding cavity. It should be noted that the specific structure of the core mold 300 is similar to the structure of the processing mold 100 of the bionic muscle prosthesis 510, and has a top mold 310, a bottom mold 350 and a core mold 330. The core mold 330 is placed between the top mold 310 and the bottom mold 350 when the two are pressed together, and the shape and size of the core mold 330 are consistent with the hollow cavity 511b in the bionic muscle prosthesis 510, that is, the size is consistent with the mold core 130 in the processing mold 100 of the bionic muscle prosthesis 510. In this way, the bionic muscle prosthesis 510 can be inserted into the core mold 330 through the hollow cavity 511b to participate in the subsequent molding process. The top mold 310 of the core mold 300 is provided with an injection port 310a, which is connected to the molding cavity. The inner wall of the molding cavity is provided with three inner wall holes respectively connected to the injection port 310a, so as to achieve the connection between the injection port 310a and the molding cavity. It can be understood that when more injection plastic is injected, the design of multiple channels can accommodate more injection plastic by diversion, thereby speeding up the injection speed.

[0046] See also Figures 1 to 4In one embodiment of the present invention, in the step of "injecting plastic into the core mold 300 and performing vulcanization molding", the temperature during vulcanization molding is 130℃-160℃, and the pressure is 20atm-50atm. It should be noted that the vulcanization temperature is set in a relatively low temperature range, so that the demagnetization of the permanent magnet 512 due to excessive temperature during the vulcanization process can be better avoided. Atm is a unit of air pressure, which refers to the standard atmospheric pressure, that is, 101325Pa. Since the permanent magnet 512 has been wrapped inside the bionic muscle prosthesis 510, the bionic muscle prosthesis 510 is supported by the core mold 330, so setting a high pressure will not cause the permanent magnet 512 to move in the mold. Setting a higher pressure range can improve the various mechanical properties of the composite bionic muscle prosthesis 500.

[0047] See also Figures 1 to 4 In one embodiment of the present invention, in the step of "inserting multiple permanent magnets 512 into multiple through holes 511a of the bionic muscle prosthesis body 511 in sequence", the permanent magnets 512 are assembled in the through holes 511a of the bionic muscle prosthesis body 511 by bonding or interference fit. It should be noted that the permanent magnets 512 and the bionic muscle prosthesis 510 are bonded with glue to fasten the permanent magnets 512, so as to prevent the permanent magnets 512 from moving inside the bionic muscle prosthesis 510 when the electromagnet 700 attracts or repels the permanent magnets 512; at the same time, when using a mold to manufacture the bionic muscle prosthesis 510, the size of the core rod 150 in the processing mold 100 of the bionic muscle prosthesis 510 can be adjusted according to the size of the permanent magnets 512 to be inserted, so as to change the size of the bionic muscle prosthesis. The size of the through hole 511a in the body 510 is such that the through hole 511a is smaller than the permanent magnet 512. During insertion, the through hole 511a can still be temporarily enlarged to accommodate the permanent magnet 512 by the elasticity of the bionic muscle prosthesis 510. After the insertion is completed, since the initial shape of the through hole 511a is smaller than the permanent magnet 512, the through hole 511a will generate pressure on the permanent magnet 512 to tighten the permanent magnet 512 and prevent the permanent magnet 512 from moving in the bionic muscle prosthesis 510. The above two fastening methods for the permanent magnet 512 can be used simultaneously or separately, and the present invention does not limit this, and the above are all within the protection scope of the present invention.

[0048] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
