FIG. 2 is a schematic view of the main pipeline structure of the present invention;

FIG. 3 is a schematic view of the structure of the auxiliary pipeline of the present invention;

the objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.

Detailed Description

The hot and cold water tap main body casting structure that this embodiment provided, refer to fig. 1 to fig. 3, and the main body casting sets up to a tube structure, including trunk line 1, the symmetry install in two auxiliary pipe 2 of trunk line 1 both sides, trunk line 1 side be equipped with respectively with two the connection port 11 that auxiliary pipe 2 is connected, connection port 11 is equipped with an annular boss 12, auxiliary pipe 2 be equipped with the annular groove 21 of annular boss 12 joint, annular boss 12 side still is equipped with an at least location boss 13, annular groove 21 side seted up with the location recess 22 of the corresponding adaptation of location boss 13, trunk line 1 with auxiliary pipe 2's concatenation department welded fastening.

It should be noted that, in this embodiment, the process for manufacturing the faucet main body casting is improved, the castings are separately cast, then the split castings are welded together by argon arc welding, then the welding seams are ground, the casting welding parts are shaped, the castings are machined, the surface of the castings is polished, and finally the manufacturing is completed by a closed water pressure test.

Specifically, according to the product requirements and the requirements of an investment precision casting process, a casting is divided into a main pipeline 1 and two auxiliary pipelines 2, the main pipeline 1 and the auxiliary pipelines 2 are clamped and connected through an annular boss 12 and an annular groove 21, and are positioned through a positioning boss 13 and a positioning groove 22, so that mould staggering is prevented, wherein in the embodiment, the positioning groove 22 and the positioning boss 13 are arranged into a group and are arranged into a rectangular structure; therefore, a complex main casting is changed into three relatively simple castings which are respectively cast, the production process of the castings is simple, and the quality is easy to guarantee. Furthermore, in the embodiment, the two secondary pipelines 2 have the same structure and are symmetrically arranged on two sides of the main pipeline 1, so that two sets of dies are only needed to be opened for the die, and the dies respectively correspond to the main pipeline 1 and the two secondary pipelines 2, after three castings are processed, the three castings are placed in a welding forming die, firstly, the two sides are respectively fixed by spot welding, then, welding wires (made of the same material as the castings) are added for overlaying welding connection gaps, and the fusion depth is ensured to be more than 2mm and cannot be weakened; after the welding is finished, the welding seam is polished to be flat and smooth by an abrasive belt machine so as to be conveniently placed into a machining fixture, and the threaded structure is machined to be connected with an external pipeline, a water tap and the like. And then carrying out surface polishing treatment, and sealing the casting to carry out a hydrostatic test, so that the water leakage is avoided.

Further, the structure of main pipeline 1 and auxiliary pipeline 2 can change according to actual demand, in this embodiment, main pipeline 1 sets up to a straight tube structure, two auxiliary pipeline 2 all sets up to 90 degrees bent pipe structures.

Further, the main pipeline 1 and the auxiliary pipeline 2 are both of a structure made of 304 stainless steel materials, and the service life of the whole casting is prolonged.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
