Description

Bimetal integrated molding faucet manufacturing method and finished product thereof

The invention relates to a faucet manufacturing method and a finished product thereof, in particular to a faucet manufacturing method and a finished product thereof, which have a bi-metal integrated molding with good structural strength and high texture characteristics.

Conventional general faucets are usually produced by turning sand into a copper material. However, such a faucet integrally formed by sand casting is inevitably suffering from many defects such as blisters, lack of materials, cracks, etc., and the inner surface of the product is relatively rough, and it is easy to leave particulate impurities such as sand core, thereby causing water plugging and dirt accumulation. In addition, in general, copper materials contain toxic lead. In order to avoid lead poisoning caused by users, the current faucets are mostly made of high-cost lead-free copper, which leads to the manufacture of such sand casting and integral molding. The method has the problems of high production cost and low market competitiveness of products.

Therefore, a manufacturer has designed a faucet consisting of a main body of the pipe and an outer cover. The main system of the pipe is formed by assembling a plurality of plastic pipes or metal pipes, and is installed in the outer cover. The cover achieves the effect of covering. However, although the faucet can reduce the production cost, regardless of whether the main body of the pipeline is made of a plastic tube or a metal tube, it has the disadvantages of being non-weatherable and not resistant to water pressure, and the plastic tube or the metal tube is leaking and leaking when it is easy to use, and The faucet structure which uses the cover to cover the main body of the pipe has a stable structure, a poor appearance and a texture, and is difficult to attract consumers' attention and purchase interest.

The present inventors have the disadvantages of poor quality, high production cost, durability, and poor texture, respectively, in view of the conventional faucets, and are based on the ideas of creation and trials, and have been tested and tried several times. After the improvement, the present invention is finally introduced.

The invention provides a bimetal integrally formed faucet manufacturing method and a finished product thereof, the manufacturing method of which is to prepare a pipeline main body having a pipeline, a tank chamber and a lock interface by a first metal which is not rust-free and non-toxic, and the pipe body is prepared The lock interface of the main body of the road is closed and closed by a cover, placed in the mold for positioning, and then the second metal is formed by die casting, casting or injection into the mold, so that the second metal is formed into a coating layer integrally formed The outer side of the main body of the pipe made of metal, the cover body is completely covered by the lock main body except the lock interface and the cover, and then the cover is removed, thereby forming a double metal integrally formed faucet.

The manufacturing method of the present invention can also prepare a pipeline main body having a pipeline, a tank chamber and a lock interface by using a first metal which is not rust-free and non-toxic, and the lock interface of the pipeline main body is covered and closed by a cover, and then adopted. In the precision dewaxing method, the second molten metal forming coating layer is integrally formed on the outer side of the pipe body made of the first metal, and the coating body completely completes the part of the pipe main body except the lock interface and the cover. Cover, then remove the cover, you can make a bi-metal integrated faucet.

The faucet finished product of the invention comprises: a pipeline body and a coating layer, the pipeline main system is made of a first metal, has a pipeline, a tank chamber and a lock interface, and the coating layer is composed of a second metal , integrally formed on the outside of the main body of the pipeline, completely covering the main part of the pipeline except the lock interface.

The main purpose of the invention is that the faucet made thereof has not only low production cost, but also has the characteristics of no rust, non-toxicity, good structural strength and high texture, and the product market competitiveness is improved.

In the following, the preferred embodiment of the present invention will be described in detail with reference to the drawings:

The method for manufacturing a bimetal integrally formed faucet according to the first, second, third, fourth, fifth, sixth and seventh figures comprises the following steps:

(2) closing and closing the lock interface B with the cover, and closing and closing the lock interface 13 of the pipe body 1 with the cover 2 to achieve isolation and protection;

(3) placing the positioning C in the mold, and positioning the pipe main body 1 covering the cover 2 into a mold 3, so that the entire pipe main body A is suspended in the mold 3, and only the cover 2 is restricted. Position reached;

(4) metal forming the second metal coating layer D, and then injecting the second metal (which may be a zinc alloy, an aluminum alloy, etc.) different from the first metal of the pipe main body 1 into the mold 3 by die casting, casting or injection. In the middle molding type, since the entire pipe main body A is suspended, the second metal forming coating layer 4 is integrally formed on the outer side of the pipe body 1 made of the first metal, by the second metal The coating layer 4 completely covers the pipe body 1 except the lock interface 13 and the cover 2, and then removes the cover 2, thereby forming the finished faucet of the bimetal integrally formed;

(5) Surface processing E, and finally the finished product of the faucet integrally formed by bimetal can be polished or plated according to requirements, and the surface is beautifully processed.

In addition, the eighth, the ninth, the tenth, the eleventh, the thirteenth, the thirteenth, the fourteenth and the fourteenth and fourteenth and the sixth and seventh figures are combined, and the bimetal integrated faucet manufacturing method of the invention comprises the following steps:

(1) prefabricating the pipe main body A1, the first metal (not lead-free copper, stainless steel, etc.) which is not rust-free and non-toxic, and the pipe main body 1 having the pipe 11, the tank chamber 12 and the lock interface 13 is prepared in advance;

(2) closing and closing the lock interface B1 with a cover, and closing and closing the lock interface 13 of the pipe body 1 with the first cover 2a to achieve isolation and protection;

(3) placing the positioning C1 in the mold, positioning the pipe main body 1 covering the first cover 2a into a mold 3a, so that the entire pipe main body 1 is suspended in the mold 3a, only the first The cover 2a limits the position to reach the position;

(4) Forming wax mold D1, the wax material melt is injected into the mold 3a, and the whole pipeline main body 1 is suspended, so that the wax material is integrally formed on the outer side of the pipe body 1 made of the first metal. a wax mold 5, by which the pipe body 1 is completely covered except for the lock interface 13 and the first cover 2a;

(5) Replace the cover E1, remove the original first cover 2a, and replace the second cover 2b of different materials;

(6) Dewaxing the second metal coating layer F1, and then covering the pipe main body 1 of the second cover 2b with the wax mold 5, grouping the tree F11, dipping and sanding F12, dewaxing F13, sintering F14, casting F15 and cutting the F16 to obtain a precision dewaxing method, forming a second metal casting F15 different from the first metal of the pipe body 1, so that the second metal forming coating layer 4 is integrally formed in the first The outer side of the pipe body 1 made of metal is completely covered by the second metal coating layer 4 except the lock interface 13 and the second cover 2b, and then the second cover is removed. Cover 2b, which is a finished faucet made of bimetal integrally formed;

(7) Surface processing G1, the final bi-metal integrated faucet finished product, can be polished or electroplated according to requirements, and the surface is beautifully processed.

As shown in the sixth and seventh figures, the faucet product of the present invention comprises: a pipe body 1 and a coating layer 4, the pipe body 1 is made of a first metal, having a pipe 11, a tank chamber 12 and the lock interface 13, the covering layer 4 is made of a second metal, integrally formed on the outside of the pipe body 1, and completely covers the pipe body except for the lock interface 13.
