Description
Technical field
The present invention relates to a kind of non-metal tap, especially, also relate to the manufacture method that this has the non-metal tap of warm-cold inleting pipe with the non-metal tap of warm-cold inleting pipe.
Background technique
The non-metal tap of the band warm-cold inleting pipe of Xiao Shouing generally comprises leading main casing in the market, have intake tunnel and exhalant canal in the tap main casing, also be provided with mangetic core assembly in the tap main casing, the tap main casing is provided with regulating handle, the leading main casing of this water tap, regulating handle, decorating spiral cover and fixed block etc. all is to make with more expensive metals such as copper, make this water tap beautiful shape, the leading main casing of water tap, handle also need be made certain shape with the decoration spiral cover, again through plating metal layer after the processing such as surface finish, so not only to expend a large amount of metals, and electroplate the pollution that can cause environment again; And contain harmful matters such as lead in the alloying metals such as cast copper, the coarse inwall of adding intake tunnel and exhalant canal adheres to dirt easily, therefore is difficult to meet high-level water hygienic requirements; The deep inside of this water tap also has complicated dark form grid slotted eye in addition, the mechanical processing difficulty of dark form grid slotted eye is very big, increase the manufacture cost of water tap greatly, simultaneously dark form grid easily causes the pore leak when casting, and makes its difficult quality control; In addition, the manufacturing process complexity of ceramic tap is produced and is renderd a service lowly, breaks easily in especially using.
Also has a kind of water tap made of plastic in the market, its leading main casing adopts casting forming, the inner flowing water passage of this water tap is more straight or curved, it can directly be loosed core with the mould of loosing core and form the flowing water passage, but the structure of this water tap can't be applicable to inside and be provided with the water tap that a plurality of complex-shaped bendings are helped secretly that the plastic faucet that for example has hot and cold intake pipe just can't be made in this way.
Summary of the invention
Technical problem to be solved by this invention provides a kind of non-metal tap with warm-cold inleting pipe, the manufacturing process of this water tap is easy, and its structure is particularly useful for warm-cold inleting pipe and the comparatively manufacturing of the flowing water passage of complicated non-metal tap of passage.Technical problem to be solved by this invention is the manufacture method that a kind of non-metal tap of above-mentioned band warm-cold inleting pipe also will be provided.
For this reason, the non-metal tap of band warm-cold inleting pipe provided by the invention comprises leading main casing, the tap main casing comprises valve seat, cold intake pipe, hot intake pipe and outlet pipe, valve seat is provided with cavity, be mounted with mangetic core assembly in the cavity, also be provided with regulating handle on the tap main casing, the leading main casing that comprises valve seat, cold intake pipe, hot intake pipe and outlet pipe is integrally formed, offer through hole on the sidewall of the flowing water passage of close leading main casing outer side surface, through hole communicates with the external world, is plugged with blocking on the through hole.
For this reason, the manufacture method of the non-metal tap of band warm-cold inleting pipe provided by the invention, comprise steps A, the prefabricated long strip mould of loosing core is inserted and secured on injection mold cavity inside, each adjacent long strip mould of loosing core is adjacent to mutually, with the loose core model of the flowing water passage in the leading main casing of mould of each long strip, make loose core mould and casting die of each long strip surround the shape that forms leading main casing; B, the nonmetallic material liquation is injected the loose core periphery of mould of inner each long strip of casting die die cavity; C: at first will have the loose core leading main casing of mould of long strip after the cooling and from casting die, deviate from, the long strip that to vertically the place mould of loosing core is extracted out from the above and below respectively then, the long strip of laterally the placing mould of loosing core is extracted out by through hole from the side, and with the blocking plug in through hole; D: the remainder that will make in addition is installed on the leading main casing.
Owing to all offer on the sidewall of the flowing water passage of the non-metal tap of band warm-cold inleting pipe provided by the invention and the extraneous through hole that communicates, through hole can be aimed at and help secretly, the manufacturer can be by through hole to originally can't be by helping secretly directly by the formation of loosing core of loosing core and form, the back through hole blocking beyond the Great Wall of loosing core, this manufacture method is simple, and the problem that can't directly loose core and obtain is helped in the bending that has solved the water tap of band warm-cold inleting pipe cleverly secretly.In addition, in the manufacture method of the non-metal tap of band warm-cold inleting pipe provided by the invention, mould cooperates the just manufacturing of the non-metal tap of the above-mentioned band warm-cold inleting pipe of full implementation with casting die but long strip is loosed core.
