[0024] The following is combined with Figure 1-8 This application is described in further detail.

[0025] Example 1 A method for producing stainless steel mold textures for condom production, such as Figure 1 As shown, the following steps are included: S1, preparing a smooth semi-finished product 7 of a stainless steel model; A stainless steel tube is welded to the head of a deep-drawn part, and then polished to obtain a smooth semi-finished product 7 in the basic shape of a condom.

[0026] In other embodiments, the smooth semi-finished product 7 in the basic shape of a condom can be obtained by spinning the steel pipe head and then polishing it.

[0027] S2, using a texture rubbing mold to make a texture on the surface of the smooth semi-finished product 7; The smooth semi-finished product 7 obtained in step S1 is placed in a texture rubbing mold to form a texture on the surface of the smooth semi-finished product 7.

[0028] S3, the finished product is completed and surface treated.

[0029] The textured products are ground and polished or subjected to surface treatments such as sandblasting, vibration grinding, magnetic grinding, etc. to eliminate surface defects of the products; subsequent nickel plating and chromium plating can also be performed to enhance the surface properties of the products.

[0030] like Figure 2 and Figure 3 As shown, the texture rubbing mold includes a base 1 and an upper mold 2, the upper mold 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 texture portion 4 for making textures, a support seat 5 is also provided on the base 1, a horizontal positioning column 6 is fixedly provided on the support seat 5, the positioning column 6 is cylindrical and is used for the smooth semi-finished product 7 to be socketed, the smooth semi-finished product 7 is specifically a stainless steel model of a condom, the length direction of the positioning column 6 is perpendicular to the horizontal sliding direction of the rubbing board 3, and limiting wheels 8 are provided on both sides above the support seat 5 corresponding to the positioning column 6, the limiting wheels 8 are rotatably connected to the support seat 5, and the limiting wheels 8 are used to press the surface of the smooth semi-finished product 7 to limit it to a certain extent.

[0031] In actual use, the outer diameter of the positioning column 6 is 0.05-1mm smaller than the inner diameter of the smooth semi-finished product 7, so that when the smooth semi-finished product 7 is sleeved on the positioning column 6, there is a certain distance between the inner wall of the smooth semi-finished product 7 and the positioning column 6, and this distance gives the smooth semi-finished product 7 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 due to the up and down action of the washboard 3 and the limiting wheel 8, and finally a texture consistent with the texture on the washboard 3 is formed on the surface of the smooth semi-finished product 7.

[0032] like Figure 2and Figure 3 As shown, a plunger 9 is provided on one side of the bottom of the upper mold 2, and a contact block 10 located below the plunger 9 and used for contacting the plunger 9 is fixedly provided on one side of the washboard 3. The abutment block 10 and the plunger 9 have inclined surfaces 11 with the same inclination and used for abutting each other. When the upper mold 2 moves downward for mold closing, the plunger 9 moves downward and drives the washboard 3 to move horizontally by abutting the inclined surface 11, and the washboard 3 is moved horizontally to complete the texture making process simultaneously. During this period, 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.

[0033] like Figure 2-Figure 3 As shown, the washboard 3 has a vertical surface 12 on one side close to the inserting knife 9, and the inserting knife 9 has a vertical surface 13 for abutting against the vertical surface 12. After the lower mold moves down to the inclined surface 11 on the inserting knife 9 and completes the abutment with the inclined surface 11 on the abutting block 10, the inserting knife 9 continues to move downward. At this time, the vertical surface 13 abuts against the vertical surface 12, which 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 inserting knife 9 drives the washboard 3 to move horizontally to complete a stroke of a circumference of the smooth semi-finished product 7, effectively realizing the control of the horizontal driving stroke of the washboard 3, and avoiding the inaccurate horizontal movement position of the washboard 3 affecting the final texture production effect.

[0034] like Figure 2-Figure 4 As shown, a return cylinder 14 is fixedly arranged on one side of the base 1, and 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 the texture on the next smooth semi-finished product 7, and realize the automatic reset of the washboard 3.

[0035] like Figure 2-Figure 5 As shown, a stripping cylinder 15 for driving the smooth semi-finished product 7 to disengage from the positioning column 6 is provided on the support seat 5, and a push ring 16 sleeved on the positioning column 6 is provided at the output end of the stripping cylinder 15. By pushing the push ring 16 to move, the smooth semi-finished product 7 is pushed to disengage from the positioning column 6 with the help of the push ring 16, thereby realizing automatic stripping of the smooth semi-finished product 7 on the positioning column 6.

[0036] like Figure 2-Figure 5As shown, in this embodiment, the support seat 5 is vertically elastically connected to the base 1, and a mounting groove 17 is opened on the base 1. A connecting column 18 extending into the mounting groove 17 is fixed on the support seat 5, and a reset spring 19 connecting the connecting column 18 and the base 1 is arranged between the two, and the reset spring 19 is used to drive the support seat 5 to move down and reset; at the same time, the top wall of the texture part 4 of this embodiment is higher than the top wall of the washboard 3, that is, a sunken part 20 for the positioning column 6 to move down is formed on the top wall of the washboard 3, and when the texture part 4 abuts against the smooth semi-finished product 7, the support seat 5 is appropriately lifted, the reset spring 19 is in a compressed state, and the smooth semi-finished product 7 is in a state of compression. The top of the finished product 7 abuts the limiting wheel 8; when the washboard 3 moves horizontally to the extreme position to complete the texture transfer, the sunken portion 20 is located below the positioning column 6 and the smooth semi-finished product 7. Under the action of the reset spring 19, the support seat 5 moves down and resets. At this time, the positioning column 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 the limiting wheel 8, which facilitates the smooth semi-finished product 7 to escape from the positioning column 6; in addition, an inclined guide surface 21 is designed on the end of the washboard 3, and the guide surface 21 facilitates the washboard 3 to abut against the smooth semi-finished product 7 for the first time and guide it to the texture portion 4 more smoothly.

[0037] like Figure 6 As shown, the texture portion 4 on the washboard 3 in this embodiment is a plurality of evenly distributed convex points 22. In other embodiments, the texture may also be dragon pattern, flame pattern, rhombus pattern, diamond pattern, etc., or may be an alternating texture of alternating distribution of large particles and small particles. In this way, concave points corresponding to the convex points 22 are formed on the surface of the smooth semi-finished product 7, and the edge R of the concave point texture is greater than or equal to 0.2 mm, and the depth is greater than or equal to 0.5 mm. Such a design ensures that the condom inflation and bursting test passes.

[0038] The working principle of the rubbing texture mold is as follows: first, the smooth semi-finished product 7 is sleeved on the positioning column 6, and then the upper mold 2 is moved downward and the rubbing board 3 is driven to move horizontally under the action of the inserting knife 9 until the texture part 4 on the rubbing board 3 abuts against the surface of the smooth semi-finished product 7. At this time, the positioning column 6 and the supporting seat 5 are properly lifted, and the top surface of the smooth semi-finished product 7 abuts against the limiting wheels 8 on both sides. Under the joint action of the limiting wheels 8 and the rubbing board 3, the surface of the smooth semi-finished product 7 is slightly deformed, so that the texture on the rubbing board 3 is transferred to the surface of the smooth semi-finished product 7. The rubbing board 3 is inserted in the inserting knife 9. After moving to the limit stroke under the action, the texture on the surface of the smooth semi-finished product 7 is completed. At this time, the sunken part 20 is located below the smooth semi-finished product 7 and the positioning column 6. Under the action of the reset spring 19, the support seat 5 and the positioning seat move down appropriately, and the top of the smooth semi-finished product 7 is separated from the abutment with the limiting wheel 8. Then the stripping cylinder 15 works to separate the smooth semi-finished product 7 from the positioning column 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 realize the production of the required texture on the surface of the smooth semi-finished product 7.

[0039] Example 2 A method for producing stainless steel mold textures for condom production, such as Figure 7 and Figure 8 As shown, the difference between this embodiment and embodiment 1 mainly lies in the different structures of the rubbing texture mold. In this embodiment, the texture portion 4 of the rubbing board 3 includes a fixed portion 23 and a movable portion 24. The movable portion 24 and the fixed portion 23 are alternately distributed at intervals. The textures are all arranged on the top walls of the movable portion 24 and the fixed portion 23. The movable portion 24 is vertically slidably connected to the rubbing board 3. The rubbing board 3 is provided with a slide groove 25 for the movable portion 24 to be vertically lifted and lowered. In addition, a lifting portion 26 is convexly provided on the top wall of the base 1. The lifting portion 26 is in the shape of a long strip and is distributed at intervals. The lifting portion 26 is arranged one by one with the movable portion 24. The side of the lifting portion 26 close to the rubbing board 3 has a guide surface 27 with a gradually changing height. In actual use, when rubbing During the horizontal movement of the plate 3, the movable part 24 will move up slightly 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. In this way, textures with alternating depths can be formed on the circumference of the smooth semi-finished product 7, and then the surface of the condoms produced subsequently will form textures with different degrees of protrusions, thereby achieving better use effects and meeting the production of textures with different degrees of protrusions. The lifting part 26 is detachably connected to the base 1 by screws. In actual use, the lifting part 26 can be used or replaced according to actual needs, so that the texture rubbing mold can meet the needs of more usage occasions and has better applicability.

[0040] In other embodiments, the lifting parts 26 with different heights can be distributed at intervals so that the texture heights on the movable parts 24 will also be different, thereby achieving more textures with different depths.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
