Description

Technical Field

[0001] This invention relates to the field of condom production models, and in particular to a method for producing stainless steel model textures for condom production. Background Technology

[0002] Condom molds are important production tools in the condom manufacturing process. Condoms are made of materials such as latex and water-based polyurethane. After the mold is washed, it is immersed in a latex tank filled with liquid latex. After being baked at high temperature, it is immersed and dried again. This process is repeated three times. After demolding and inspection, the production of condoms is completed.

[0003] Currently, condom production molds are generally made of glass. However, many stages of condom production require heating. In the current context of energy conservation and green manufacturing, energy saving is a crucial demand and trend for the future development of enterprises. Metal sheet materials, on the other hand, offer stable dimensional accuracy, good thermal conductivity, corrosion resistance, and can be produced in various thicknesses. These characteristics perfectly meet the requirements of condom production. Large-particle condoms refer to condoms with granular or spiral-shaped protrusions on their surface. During use, they provide a more pronounced frictional stimulation, enhancing contact sensitivity and potentially preventing the spread of diseases to some extent. How to create metal molds to replace traditional glass molds and achieve a uniform texture on the surface of the metal molds is a pressing challenge that needs to be overcome. Summary of the Invention

[0004] In order to produce stainless steel models and form a uniform texture on the surface, this application provides a method for producing stainless steel model textures for condom production.

[0013] Optionally, the outer diameter of the positioning post is 0.05-1mm smaller than the inner diameter of the smooth semi-finished product.

[0014] Optionally, a support base is connected to the positioning column, the support base is vertically elastically connected to the base, and a return spring is provided between the base and the support base to connect the two, the return spring being used to drive the support base to move down and reset.

[0015] Optionally, the top wall of the textured portion is higher than the top wall of the washboard, and a recess is formed on the top wall of the washboard to allow the positioning post to move downward.

[0016] Optionally, it also includes an upper mold, on which a cutting tool is provided. The washboard and the cutting tool are provided with inclined surfaces for mutual contact. The cutting tool moves downward to drive the washboard to move horizontally. The washboard has a vertical surface on the side near the cutting tool.

[0035] The following is in conjunction with the appendix Figure 1-8This application will be described in further detail.

[0036] Example 1

[0037] A method for producing stainless steel model textures for condom production, such as Figure 1 As shown, it includes the following steps:

[0038] S1, Prepare the smooth semi-finished product 7 of the stainless steel model;

[0039] The stainless steel tube and the head of the deep-drawn part are welded together, and then polished to obtain a smooth semi-finished product with the basic shape of a condom.

[0040] In other embodiments, a smooth semi-finished product 7 with the basic shape of a condom can be obtained by spinning the head of a steel tube and then polishing it.

[0041] S2, a texture-making die is used to create a texture on the surface of the smooth semi-finished product 7;

[0042] The smooth semi-finished product 7 obtained in step S1 is placed into the texture mold to form a texture on the surface of the smooth semi-finished product 7.

[0043] S3, the finished product is completed and surface treatment is performed.

[0044] After the texture is formed, the product is polished or subjected to surface treatments such as sandblasting, vibratory grinding, and magnetic grinding to eliminate surface defects. Subsequent electroplating with nickel or chromium can also be performed to enhance the surface properties of the product.

[0045] like Figure 2 and Figure 3 As shown, the textured die includes a base 1 and an upper die 2. The upper die 2 is located directly above the base 1. A rubbing board 3 is horizontally slidably connected to the base 1. The rubbing board 3 has a textured part 4 for creating textures. A support base 5 is also provided on the base 1. A horizontal positioning post 6 is fixedly provided on the support base 5. The positioning post 6 is cylindrical and is used for fitting a smooth semi-finished product 7. The smooth semi-finished product 7 is a stainless steel model of a condom. The length direction of the positioning post 6 is perpendicular to the horizontal sliding direction of the rubbing board 3. Limiting wheels 8 are provided on both sides above the positioning post 6 on the support base 5. The limiting wheels 8 are rotatably connected to the support base 5 and are used to press against the surface of the smooth semi-finished product 7 to limit it to a certain extent.

[0046] In actual use, the outer diameter of the positioning post 6 is 0.05-1mm smaller than the inner diameter of the smooth semi-finished product 7. This results in a certain gap between the inner wall of the smooth semi-finished product 7 and the positioning post 6 when the smooth semi-finished product 7 is fitted onto the positioning post 6. This gap provides the smooth semi-finished product 7 with a certain deformation space. When the washboard 3 moves horizontally until the texture on the surface of the washboard 3 contacts the surface of the smooth semi-finished product 7, the surface of the smooth semi-finished product 7 undergoes a certain deformation along with the texture under the up-and-down action of the washboard 3 and the limiting wheel 8. Finally, a texture consistent with the texture on the washboard 3 is formed on the surface of the smooth semi-finished product 7.

[0047] like Figure 2 and Figure 3 As shown, a cutting tool 9 is provided on one side of the bottom of the upper mold 2, and an abutment block 10 is fixedly provided on one side of the washboard 3, located below the cutting tool 9 and used to contact it. The abutment block 10 and the cutting tool 9 have inclined surfaces 11 with the same inclination for mutual abutment. When the upper mold 2 moves down to close the mold, the cutting tool 9 moves down and drives the washboard 3 to move horizontally with the abutment of the inclined surface 11. The washboard 3 moves horizontally to complete the texture production process. During this process, no additional driving source is required to drive the washboard 3 to move horizontally. The structure is more simplified and simple, and the production cost is effectively reduced.

[0048] like Figures 2-3 As shown, the washboard 3 has a vertical surface 12 on the side near the insert 9. The insert 9 has a vertical surface 13 for abutting against the vertical surface 12. After the lower mold moves down to the point where the inclined surface 11 on the insert 9 abuts against the inclined surface 11 on the abutting block 10, the insert 9 continues to move down. At this time, the vertical surface 13 abuts against the vertical surface 12. This represents the completion of the horizontal movement stroke of the washboard 3. That is, when the vertical surface 13 abuts against the vertical surface 12, the insert 9 drives the washboard 3 to move horizontally to complete a stroke of one circumference of the smooth semi-finished product 7. This effectively controls the horizontal driving stroke of the washboard 3 and avoids the inaccurate horizontal movement position of the washboard 3 from affecting the final texture production effect.

[0049] like Figures 2-4 As shown, a return cylinder 14 is fixedly installed on one side of the base 1. The output end of the return cylinder 14 is connected to the washboard 3 to drive the washboard 3 to move horizontally and reset, so as to facilitate the production of texture on the next smooth semi-finished product 7 and achieve automatic reset of the washboard 3.

[0050] like Figures 2-5 As shown, a stripping cylinder 15 is provided on the support base 5 to drive the smooth semi-finished product 7 out of the positioning post 6. The output end of the stripping cylinder 15 is provided with a push ring 16 sleeved on the positioning post 6. By pushing the push ring 16 to move, the smooth semi-finished product 7 is pushed out of the positioning post 6 by means of the push ring 16, so as to realize the automatic stripping of the smooth semi-finished product 7 on the positioning post 6.

[0051] like Figures 2-5As shown, in this embodiment, the support base 5 is vertically elastically connected to the base 1. An installation groove 17 is provided on the base 1. A connecting post 18 extending into the installation groove 17 is fixed on the support base 5. A return spring 19 is provided between the connecting post 18 and the base 1 to connect the two. The return spring 19 is used to drive the support base 5 to move downwards and reset. Simultaneously, in this embodiment, the top wall of the textured part 4 is higher than the top wall of the washboard 3, i.e., a recessed part 20 is formed on the top wall of the washboard 3 for the positioning post 6 to move downwards. When the textured part 4 abuts against the smooth semi-finished product 7, the support base 5 is appropriately raised, and the return spring 19 is in a compressed state. The top of the finished product 7 abuts against the limiting wheel 8; after the washboard 3 moves horizontally to the limit position to complete the texture transfer, the recessed part 20 is located below the positioning post 6 and the smooth semi-finished product 7. Under the action of the return spring 19, the support seat 5 moves down to reset. At this time, the positioning post 6 and the smooth semi-finished product 7 move down appropriately, so that the top of the smooth semi-finished product 7 no longer abuts against the limiting wheel 8, which facilitates the smooth semi-finished product 7 to be removed from the positioning post 6; in addition, an inclined guide surface 21 is designed on the end of the washboard 3. The guide surface 21 facilitates the initial contact between the washboard 3 and the smooth semi-finished product 7, guiding it more smoothly to the texture part 4.

[0052] like Figure 6 As shown, in this embodiment, the textured part 4 on the washboard 3 consists of multiple evenly distributed protrusions 22. In other embodiments, the texture can also be a dragon pattern, flame pattern, rhombus pattern, or diamond pattern, or an alternating texture of large and small particles. In this way, concave points corresponding to the protrusions 22 are formed on the surface of the smooth semi-finished product 7. The edge R of the concave texture is greater than or equal to 0.2 mm, and the depth is greater than or equal to 0.5 mm. This design ensures that the test of the condom bursting is passed.

[0053] The working principle of the texture-printing mold: First, the smooth semi-finished product 7 is fitted onto the positioning post 6. Then, the upper mold 2 moves downward, and under the action of the inserter 9, the rubbing plate 3 moves horizontally until the textured part 4 on the rubbing plate 3 abuts against the surface of the smooth semi-finished product 7. At this time, the positioning post 6 and the support base 5 are appropriately raised, and the top surface of the smooth semi-finished product 7 abuts against the limiting wheels 8 on both sides. Under the combined action of the limiting wheels 8 and the rubbing plate 3, the surface of the smooth semi-finished product 7 is slightly deformed, realizing the transfer of the texture on the rubbing plate 3 to the surface of the smooth semi-finished product 7. The rubbing plate 3 is under the action of the inserter 9. After moving to its limit stroke under the action, the texture is created on the surface of the smooth semi-finished product 7. At this time, the recessed part 20 is located below the smooth semi-finished product 7 and the positioning post 6. Under the action of the return spring 19, the support seat 5 and the positioning seat move down appropriately, and the top of the smooth semi-finished product 7 disengages from the contact with the limit wheel 8. Then the ejector cylinder 15 works to remove the smooth semi-finished product 7 from the positioning post 6. After the upper mold 2 moves up and resets, the return cylinder 14 drives the washboard 3 to move horizontally and reset. This cycle can achieve the desired texture on the surface of the smooth semi-finished product 7.

[0054] Example 2

[0055] A method for producing stainless steel model textures for condom production, such as Figure 7 and Figure 8 As shown, the main difference between this embodiment and Embodiment 1 lies in the structure of the texture mold. In this embodiment, the texture part 4 of the rubbing board 3 includes a fixed part 23 and a movable part 24. The movable part 24 and the fixed part 23 are alternately distributed. The texture is set on the top wall of the movable part 24 and the fixed part 23. The movable part 24 is vertically slidably connected to the rubbing board 3. The rubbing board 3 has a groove 25 for the movable part 24 to rise and fall vertically. In addition, a lifting part 26 is protruding on the top wall of the base 1. The lifting part 26 is long and spaced apart. The lifting part 26 is arranged one-to-one with the movable part 24. The side of the lifting part 26 near the rubbing board 3 has a guide surface 27 with a gradually changing height. In actual use, when rubbing... During the horizontal movement of plate 3, the movable part 24 moves slightly upward under the action of the lifting part 26, so that the texture height of the top wall of the movable part 24 is different from that of the fixed part 23. This can form alternating textures of different depths on the circumference of the smooth semi-finished product 7, and thus the surface of the condom produced later will have textures of different degrees of protrusion, achieving better use effect and meeting the production needs of textures with different degrees of protrusion. The lifting part 26 and the base 1 are detachably connected by screws. In actual use, the lifting part 26 can be used or replaced with a lifting part 26 of different heights according to actual needs, so that the texture die can meet the needs of more application occasions and has better applicability.

[0056] In other embodiments, raised portions 26 of different heights can be spaced out, so that the texture height on each movable portion 24 will also be different, thus enabling the creation of more textures of different depths.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
