Description
Technical field
The present invention relates to a kind of preparation process of water tap.
Background technique
Water tap is extensive use of in daily life, and existing water tap is generally metal faucet, the water tap of making as copper product, stainless steel material.But because the metallic material price is more expensive, make that the cost of water tap is higher.At this problem, people have designed the water tap that adopts plastic materials to make.
The preparation process of a kind of water tap of prior art may further comprise the steps: steps A, the shape of the outlet pipe pipeline of the plastic faucet of Sheng Chaning processing embedding piece as required; Step B is positioned in the mould embedding piece in the die cavity of shaping outlet pipe by locating piece; Step C, injection molded; Step D, perforate on the tube wall of the outlet pipe of the plastic faucet base substrate after the shaping is extracted embedding piece out by instrument then from the hole, and extracting the space of reserving behind the embedding piece out is the pipeline of outlet pipe; Step e is with the perforate on the plug sealing outlet pipe tube wall.There is following defective in the preparation process of a kind of water tap of this kind prior art: because need perforate on the tube wall of the outlet pipe of the plastic faucet base substrate that is shaped, by instrument embedding piece is extracted out from the hole then, this process operation is difficulty quite, can reduce manufacturing efficiency, and this kind manufacture method can only be the plastic faucet of straight tube for the manufacture of outlet pipe generally, if outlet pipe is bend pipe, especially complex-shaped bend pipe, embedding piece just can't be extracted out from the hole, therefore, make that the shape of outlet pipe of plastic faucet is more single; Again owing to the perforate on the plug sealing outlet pipe tube wall, if sealing effect is bad between Sealing and the hole wall, water leakage phenomenon will occur, thereby can make troubles to the user.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, provide a kind of easy to process, can be used for processing water pipe and be the plastic faucet body of bend pipe, particularly complex-shaped bend pipe and the preparation process of a kind of water tap that the outlet pipe of the plastic faucet that is processed into can not leak.
To achieve these goals, the present invention adopts following technological scheme:
Technical solution of the present invention is, a kind of preparation process with a kind of water tap of following structure is provided, and it may further comprise the steps:
(1) metal insert that is provided with passage that matches with it according to the shape processing of the outlet pipe pipeline of the plastic faucet that will make;
(2) distinguish first plug and second plug beyond the Great Wall at the two ends of metal insert;
(3) metal insert that two ends is plugged with plug is positioned at by locating piece and is used in the die cavity of shaping outlet pipe in the mould, periphery wall on described metal insert one end and first plug are against first punch that is used for shaping plastic faucet outlet pipe water outlet in the mould, and described second plug is against second punch that is used for shaping plastic faucet valve core case cavity in the mould;
(4) injection molded is the plastic faucet base substrate;
(5) remove second plug on the metal insert end, the pipeline of metal insert is communicated with the cavity of valve core case, perforate on the wall between valve core case and the intake pipe simultaneously makes the valve core case cavity be communicated with intake pipe;
(6) periphery wall that is positioned at that end of outlet pipe water outlet at metal insert is left the water hole, and the pipeline in the metal insert is communicated with the water outlet of outlet pipe;
(7) at the internal thread of the inwall of the valve core case system of getting on the bus for the connection spool, plastic faucet body machines.
As a kind of improvement of the present invention, in (3) step, described locating piece and second plug are connected in one, and the lower end of this locating piece and second punch is located by connecting.This kind is designed to optimum implementation.
As another kind of improvement the of the present invention, the lower end of described locating piece and second punch is located by connecting and refers to, the lower end of described second punch is provided with positioning convex, and the upper end of described locating piece is provided with positioning groove, and described positioning convex is embedded in the described positioning groove.The relational structure that is located by connecting between this kind locating piece and second punch is simple, realizes easily.
Also have a kind of improvement as of the present invention, described metal insert is the inserts that stainless steel material is made.Because the stainless steel long service life, can polluted source, therefore, can prolong the working life of plastic faucet, nor can polluted source.
The present invention compared with prior art, its beneficial effect is:
(1) because metal insert of the present invention is the metal insert that is provided with pipeline, behind the injection molded, described metal insert is stayed in the outlet pipe, as long as remove second plug on the metal insert end, the periphery wall of end that is positioned at the water outlet of outlet pipe at metal insert is left the water hole, the pipeline of metal insert just is communicated with the cavity of valve core case and the water outlet of outlet pipe, compared with prior art, the preparation process of a kind of water tap of the present invention need not metal insert is taken out in outlet pipe, make processing very convenient, can enhance productivity, and can be bend pipe for the manufacture of outlet pipe, particularly the plastic faucet body of complex-shaped bend pipe makes that the shape of outlet pipe can be not dull; Again owing to do not have perforate on the outlet pipe by the produced plastic faucet body of the present invention, so outlet pipe water leakage phenomenon can not occur, thereby the user is without fear of an attack from the rear.
(2) preparation process of this kind water tap is easy to process, can be used for processing water pipe and be the plastic faucet body of bend pipe, particularly complex-shaped bend pipe and the outlet pipe of the plastic faucet that is processed into can not leak.
