Description

A kind of modularized non-metal water tap and manufacture method thereof

Technical field

The present invention relates to a kind of modularized non-metal water tap, also relate to the manufacture method of this modularized non-metal water tap.

Background technique

A kind of water tap has appearred in the market, it comprises leading main casing, mangetic core assembly, intake pipe and outlet pipe, valve seat is provided with cavity, mangetic core assembly is arranged in the cavity, also be provided with regulating handle on the tap main casing, be provided with inside liner in the body cavity of tap main casing and the fluid passage, the whole outer surface of this inside liner is enclosed with plastics, and this inside liner can adopt pottery or plastics or stainless steel etc. to make; But this water tap has following shortcoming 1, cost of material higher, above-mentioned inside liner must comprise the inside liner of valve seat cavity, intake tunnel and exhalant canal etc., and selecting for use of the material of inside liner had relatively high expectations, must meet requirements such as environmental protection, high temperature resistant, corrosion-resistant, high strength, so large size adopts this expensive material can improve cost of material; 2, the manufacturing process complexity, be difficult to operation, these inside liners can not directly insert in these cavitys and the passage, more feasible way is: A, valve seat cavity inside liner with split, intake tunnel inside liner and exhalant canal inside liner are mould, cooperate casting die, the injection material liquation is made leading main casing, B, with the valve seat cavity, the integral production of the inside liner of intake tunnel and exhalant canal is shaped, with integrally formed integral lining layer is mould, and cooperation casting die, inside liner and mould are surrounded form leading main casing shape, and injection material liquation, through obtaining having the leading main casing of inside liner after the demoulding, but be difficult to too much in casting die, locate owing to inside liner quantity in the A kind method, and the passage that inside liner comprises in the B kind method is too much, be difficult to make, run into have that bending helps secretly with the water tap of cold intake pipe and hot intake pipe the time, the manufacturing process of this inside liner is complicated more, especially must after making, be welded to each other respectively between each channel pattern, and this welding is very difficult, trouble; 3, the profile of manufactured good generally is not very attractive in appearance, the leading main casing of this water tap by plastics through an injection moulding postforming grade, because each position became uneven of leading main casing, and be subjected to the restriction of existing Shooting Technique, this its outer surface of product that obtains through an injection moulding generally all can be uneven, very influences attractive in appearance.

A kind of water tap has also appearred in the market, this water tap comprises inner structure main body and outer layer plastic layer, the inner structure main body comprises spool, valve seat, warm-cold inleting pipe and outlet pipe, plastic layer contains outlet pipe and warm-cold inleting pipe, but the position of this water tap cladding plastic layer is less, can't reduce cost significantly, the major component of its leading main casing still constitutes expensive materials such as the stainless steel of inner structure main body, and the parts that the inner structure main body comprises are more, and inner passage complexity, so also relative complex of manufacturing process.

Summary of the invention

Technical problem to be solved by this invention provides a kind of modularized non-metal water tap, and the manufacturing process of this modularized non-metal water tap is easy, helps socialization division of labor continuous productive process, and then can enhance productivity, and reduces production costs.The present invention also will provide the manufacture method of this blocking non-metal tap.

For this reason, modularized non-metal water tap provided by the invention comprises leading main casing, be provided with the flowing water passage in the tap main casing, the top of tap main casing also has valve seat, the tap main casing comprises the module that a plurality of nonmetallic material are made, and each module is cut apart by leading main casing longshore current water channel and formed, and each module all has the tube wall of flowing water passage, mate mutually on mating face between each module, and each module is docked the back mutually and constituted leading main casing on the mating face.

For this reason, the present invention also provides a kind of manufacture method of modularized non-metal water tap, and the module that it comprises A, will constitute leading main casing is made shaping respectively; B, with each module locate on its mating face mutual welding or bonding formation the tap main casing, the leading main casing of welding or bonding formation is positioned in the casting die, nonmetal liquation is injected the cavity that forms between leading main casing outer surface and the casting die internal surface, make between leading main casing and the casting die to form the nonmetal back-up coat that wraps up leading main casing outer wall fully, with cooled leading main casing together with the nonmetal back-up coat demoulding; C, the parts that will make in addition are installed on the leading main casing.

The present invention also provides a kind of manufacture method of modularized non-metal water tap for this reason, and the module that it comprises A, will constitute leading main casing is made shaping respectively; B, each module amalgamation is formed leading main casing, the leading main casing that pieces together directly is positioned in the casting die, make between the inwall of the outer surface of leading main casing and casting die and form nonmetal back-up coat; C, the parts that will make in addition are installed on the leading main casing.

Because the leading main casing of modularized non-metal water tap of the present invention is shaped in mating face amalgamation butt joint by a plurality of modules, therefore adding the module that to produce solid shape man-hour in enormous quantities, docking amalgamation then gets final product, in the whole production flow process, be separated from each other between each operation, can finely be connected again, the principle that very meets modernized continuous productive process, and when production has the non-metal tap that bending helps secretly, also the sidewall of passage can be included in respectively in the different modules, the amalgamation butt joint is shaped then, perhaps the nonmetal back-up coat of amalgamation butt joint casting gets final product, the bending that this production model has solved water tap in the production model of old non-metal tap help secretly can't be directly problem by casting forming, and need not with the flowing water channel pattern as liner, saved the cost of material of making the flowing water channel pattern, and need not a plurality of flowing water channel patterns are inserted and carry out loaded down with trivial details location in the casting die, can enhance productivity greatly.
