Description
Technical field
The utility model belongs to condom manufacture mould applications, is specifically related to a kind of polyurethane rubber latex condom manufacture mould.
Background technology
Sheath is current one of most widely used contraceptive device in the world.In prior art, the main raw material(s) manufacturing sheath is Heveatex, but natural latex condom also exists the risk of sensitization and nitrosamine cause cancer.Therefore, finding one more suitably raw material production sheath, is the inexorable trend of condom manufacture development.
Compared with natural latex condom, polyurethane condom have nontoxic, intensity is high, thermal conductivity good, without features such as allergic reactions, to heat, wet and ultraviolet light is insensitive, and ageing-resistant performance is good, the impact not by various oil lubricant in storage process.The barrier effect of polyurethane condom is high, can effectively practise contraception and filter AIDS virus, is a kind of use safety, comfortable sheath.
Sheath generally adopts the explained hereafter of straight dipping process, natural latex condom mold material general is at present generally glass, pottery and stainless steel etc., but polyurethane is extremely strong at above-mentioned material surface adhesive force, with die adhesion, there is the problem being difficult to crimping, demoulding.Publication number is adopt polytetrafluoroethylene (PTFE) material to solve release problems in the Chinese patent application of CN1285364A and CN 102107473 A, but polytetrafluoroethylene (PTFE) is expensive, density large and processing very difficulty.On a production line, the clamping of apparatus for mold clamping that mould need adopt, dismantles, installs extremely inconvenient, waste time and energy.
Utility model content
The utility model will for solve problem be the production that existing natural latex condom production mould (glass, stainless steel) can not adapt to polyurethane rubber latex sheath, a kind of polyurethane rubber latex condom manufacture mould is provided.
For solving the problems of the technologies described above, the utility model provides a kind of polyurethane rubber latex condom manufacture mould, comprise plush copper, cylinder and annulus mat, described plush copper is integrally formed in the front end of described cylinder, described cylinder comprises body and joint pin, described annulus mat is arranged between described body and joint pin, and described joint pin is formed with external screw thread.
Further, described polyurethane rubber latex condom manufacture mold integral adopts polyethylene or polypropylene material to make.Compared with glass, stainless steel, the adhesion of polyurethane laminate reduces greatly, effectively can solve the problem of crimping, demoulding difficulty.
Further, the total length of described polyurethane rubber latex condom manufacture mould is more than or equal to 300mm.
Further, the external diameter of described cylinder is 28 ~ 42mm.
Further, described cylinder is solid construction.
Further, described cylinder is hollow-core construction.
Further, the wall thickness of the cylinder of described hollow-core construction is 1 ~ 15mm.
Polyurethane rubber latex condom manufacture mould of the present utility model, the joint pin of annulus mat side is formed with external screw thread, be directly connected in impregnator mold base screwed hole, separately need not add apparatus for mold clamping, dismounting, install very convenient, employing condom production equipment, production technology can obtain polyurethane rubber latex sheath, are suitable for producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the structural representation of the polyurethane rubber latex condom manufacture mould of the solid construction that the utility model one embodiment provides;
Fig. 2 is the structural representation of the polyurethane rubber latex condom manufacture mould of the hollow-core construction that the utility model one embodiment provides.
Reference numeral is as follows:
1, plush copper; 2, cylinder; 21, body; 22, joint pin; 3, annulus mat; 4, external screw thread.
Detailed description of the invention
embodiment one
The polyurethane rubber latex condom manufacture mould that the present embodiment provides, as shown in Figure 1, comprise plush copper 1, cylinder 2 and annulus mat 3, described plush copper 1 is integrally formed in the front end of described cylinder 2, described cylinder 2 comprises body 21 and joint pin 22, described annulus mat 3 is arranged between described body 21 and joint pin 22, and described joint pin 22 is formed with external screw thread 4.
As shown in Figure 1, the polyurethane rubber latex condom manufacture mould that the present embodiment provides is solid construction, and namely cylinder 2 is solid construction.
In the present embodiment, described polyurethane rubber latex condom manufacture mold integral adopts polyethylene or polypropylene material to make.Compared with glass, stainless steel, the adhesion of polyurethane laminate reduces greatly, effectively can solve the problem of crimping, demoulding difficulty.
In the present embodiment, mould total length is 350mm, the external diameter 32mm of cylinder 2.
embodiment two
The polyurethane rubber latex condom manufacture mould that the present embodiment provides, as shown in Figure 2, comprise plush copper 1, cylinder 2 and annulus mat 3, described plush copper 1 is integrally formed in the front end of described cylinder 2, described cylinder 2 comprises body 21 and joint pin 22, described annulus mat 3 is arranged between described body 21 and joint pin 22, and described joint pin 22 is formed with external screw thread 4.
As shown in Figure 2, the polyurethane rubber latex condom manufacture mould that the present embodiment provides is hollow-core construction, and namely cylinder 2 is hollow-core construction.
In the present embodiment, described polyurethane rubber latex condom manufacture mold integral adopts polyethylene or polypropylene material to make.Compared with glass, stainless steel, the adhesion of polyurethane laminate reduces greatly, effectively can solve the problem of crimping, demoulding difficulty.
In the present embodiment, mould total length is 350mm, the external diameter 32mm of cylinder 2, and the wall thickness of cylinder is 1 ~ 15mm.
The polyurethane rubber latex condom manufacture mould of the utility model above-described embodiment, the joint pin of annulus mat side is formed with external screw thread, is directly connected in impregnator mold base screwed hole, separately need not adds apparatus for mold clamping, dismounting, install very convenient.And, polyurethane rubber latex condom manufacture polyethylene provided by the utility model or polypropylene material mould effectively can solve the problem that the material moulds such as existing glass, stainless steel are difficult to crimping, the demoulding, and have that quality is light, low price and advantage easy to process, employing condom production equipment, production technology can obtain polyurethane rubber latex sheath, are suitable for producing in enormous quantities.
The utility model is not limited to above-mentioned embodiment, every spirit and scope of the present utility model are not departed to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model also means that comprising these changes and modification.
