Abstract

The utility model provides a combined type faucet body structure. The combined type faucet body structure comprises an inner shell body and an outer shell body coated on the external surface of the inner shell body. The inner shell body is formed in a manner that two half shell bodies which are formed by die-casting an aluminum alloy material with a higher melting point are mutually assembled. The outer shell body is formed in a manner that a zinc alloy material with a lower melting point is coated on the inner shell body by using a die-casting manner again. According to the combined type faucet body structure, a two-time die-casting manner is adopted, so that the combined type faucet body structure can be used for producing products of streamlined appearances or other complicated appearances and has the advantages of reliability in manufacture, high speed and low cost.

Description

The compound tap body structure

Technical field

The utility model relates to a kind of water tap, relates in particular to a kind of frame one of being made by zinc alloy material and is coated on the formed compound tap body structure of the inner housing of being made by aluminum alloy material.

Background technique

Existing faucet body adopts copper metallic material casting mostly, and its shortcoming is that copper metallic material cost is high, and easily causes dust pollution after the core casting adopted of when casting.The casting flow process is tediously long, easily produces the sand hole phenomenon in the process, affects product yield.

Also have the part faucet body to adopt iron and steel or stainless steel material to make, to reduce cost.Wherein, ferrous materials easily produces corrosion, must at the surface-coated anticorrosive paint, easily come off but paint, thereby can't avoid corrosion fully.Adopt in addition and electroplate or the technology such as anode processing, chromium plating or coating glue material, easily be subject to pipe fitting length, volume, quantity and cost factor and limit.Although the stainless steel material rust resistance is higher, the high difficult processing of hardness therefore processing cost is high, needs with the lost wax casting moulding for the anomalous water road shape, and cost is more expensive.

The model utility content

Main purpose of the present utility model is to provide a kind of compound tap body structure, not only can simplify processing procedure, improves speed of production and yield, reduces cost, more can be in order to manufacture the product of sweeping appearance or other complicated appearances.

To achieve these goals, a kind of compound tap body structure that the utility model provides is characterized in that, comprising:

One inner housing is mutually docked by two and half housings of aluminum alloy material die cast and to form, and is formed with an inner flow passage, a water intake, a water outlet and a valve pool;

One frame is coated on the outer surface of described inner housing by zinc alloy material die cast and one.

Preferably, the inner housing of described compound tap body structure, two half housing is bilateral symmetry roughly.

Preferably, the inner housing of described compound tap body structure combines by at least one positioning pipe and the relative eye-splice of at least one locating column between two half inner walls.

The compound tap body structure that the utility model provides, owing to adopting the secondary die cast, therefore, compared to traditional copper product casting, not only processing procedure is significantly simplified, speed of production is fast, more can improve yield and reduce cost, can also be used to manufacture the product of sweeping appearance or other complicated appearances.

Embodiment

Further specify the technical solution of the utility model below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Shown in Fig. 1 to 2, the utility model provides a kind of compound tap body 1 structure, mainly comprises an inner housing 2 and a frame 3; Below be for the explanation of above-mentioned composition member division.

Described inner housing 2 is that two and half housings by the aluminum alloy material die cast mutually dock and form.

Described frame 3 is formed by zinc alloy material die cast and the outer surface that is coated on described inner housing 2.

Be formed with an inner flow passage 21 on the described inner housing 2, be communicated in a water intake 22, a water outlet 23 at described inner flow passage 21 two ends respectively, and one is communicated in inner flow passage 21 near the valve pool 24 at water intake 22 places.Described valve pool 24 can supply to install a control valve group (not shown), thereby by switch control current.

As shown in Figure 3, the making step of compound tap body 1 of the present utility model, comprise and purchase one first die casting mould 4, described the first die casting mould 4 inside are provided with left and right two

die cavitys

41,42, insert in above-mentioned mould 4 each

die cavity

41,42 and carry out die casting preparing the aluminum alloy material idiosome that roughly is half shelly in advance, can mold shown in Fig. 4 to 5 roughly symmetrical 1 the first half housing 201 and one the second half housing 202.

Described the first half housing 201 internal faces are provided with two positioning pipes 203, and described the second half housing 202 internal faces are relatively set with two locating columns 204; Accordingly, described the second half housings 202 can be positioned to make each other firmly to fit together, to form an internal component 20 as shown in Figure 6 in the first half housing 201 each relative positioning pipe 203 by its each locating column 204 relative intercalations; Wherein, these internal component 20 major parts are to consist of above-mentioned inner housing 2.

Then, as shown in Figure 7, purchase in addition one second die casting mould 5, described mould 5 inside are provided with a die cavity 51, above-mentioned internal component 20 is positioned in the pre-prepd roughly cylindrical zinc alloy material idiosome, insert together again in the die cavity 51 of above-mentioned mould 5 and carry out die casting, can go out an above-mentioned frame 3 these internal component 20 outside one are Overmolded, see outside forming as shown in Figure 8, at last, again with internal component 20 with respect to feed-water end, the position of waterexit end and valve pool cuts, to form respectively above-mentioned water intake 22, water outlet 23 and valve pool 24, so, can obtain rapidly compound tap body 1 structure of the utility model.

The compound tap body 1 that the utility model provides adopts the secondary die cast, utilizes copper metallic material casting mode compared to tradition, can significantly reduce cost, and manufacturing speed is fast, and yield is high, does not more have the problem of dust pollution.Adopt the manufacture of ferrous materials or stainless steel material compared to tradition, then do not have corrosion or be difficult for the problems such as processing, processing cost height, also can be used to make the product of sweeping appearance or other complicated appearances.
