Description
Technical field
The utility model belongs to Technology of EPC field, and in particular to a kind of negative pressure lost foam for triple valve is cast
Make structure.
Background technology
At present, for the casting of triple-valve body, using clay sand mold or resin sand casting it is all very difficult, due to product outside
Shape is small, and many curved surfaces in inner chamber, core pulling is extremely difficult, and core cleaning difficulty is big during post processing, low production efficiency, product qualified rate less than
70%。
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems, a kind of and negative-pressure los mould casting for triple valve of proposition
Structure.
Main technical schemes of the present utility model：The negative-pressure los mould casting structure of triple valve, includes the triple valve of shaping
The white module of body, it is characterised in that the white module of triple-valve body is bonded successively by tetrameric white mould to be constituted：According to triple valve
Planform, is divided into Part I, Part II, Part III and Part IV, each part by valve body according to architectural feature
Each self-forming of white mould, wherein Part IV includes the same white mould of two planforms；The Part I is in valve body
Section, Part II and Part III are the epimere of valve body, the leading portion and back segment for valve body of Part IV.
Usually, the special glue sticking of commercially available lost foam casting is passed through between the white mould of each several part.
The utility model when in use, generally comprises following steps：The white mould sectional forming of valve body, is segmented white mould bonding group
Type, the white die coating material of valve body is coated with；Moulding is poured into a mould and cleared up.
The utility model instead of the form of unselected clay sand mold or resin sand casting manufacture part, simplify founder
Skill, yield rate is up to more than 96%, and cost is low, and environmental protection economy.

Embodiment
The utility model is described in detail in reference to embodiment and accompanying drawing.
Embodiment：The negative-pressure los mould casting structure of triple valve referring to accompanying drawing 5, including shaping the white module of triple-valve body,
It is that the white module of triple-valve body is bonded and constituted successively by tetrameric white mould that it, which is mainly improved,：, will according to the planform of triple valve
Valve body is divided into Part I 1, Part II 2, Part III 3 and Part IV 4 according to architectural feature（Referring to accompanying drawing 1-4）, often
Each self-forming of white mould of individual part, wherein Part IV 4 include the same white mould of two planforms；The Part I 1 is
The stage casing of valve body, Part II 2 and Part III 3 are the epimere of valve body, the leading portion and back segment for valve body of Part IV 4.
In embodiment, pass through the special glue sticking of commercially available lost foam casting between the white mould of each several part.
Embodiment is used in the negative-pressure los mould casting of triple-valve body, comprises the steps of：The white mould of triple-valve body is segmented into
Type；The white mould bonding group type of triple-valve body;The white die coating material of triple-valve body is coated with；Moulding is poured into a mould and cleared up.
Each section of white mould portion is molded respectively, and the white mould various pieces of the triple-valve body after shaping are with commercially available lost foam casting special glue
The bonding composition white module group type of triple-valve body, the bonding white membrane module of rear valve body is coated with commercially available paint specially for disappearing cast mold, is coated with
The hydrops in time control dry type intracavitary portion, in case piling, is put into after being dried in 40 ~ 55 DEG C of baking rooms after being coated with, by above-mentioned side
Method is coated with second throughout the 3rd time, be put into 40 ~ 55 DEG C of baking rooms dry it is stand-by.
Moulding uses rain type sand injection manner, shakes consolidation 50 ~ 52HZ of frequency, and vibrations total time is 10 ~ 12 minutes.Cast
Temperature control pours into a mould 0.020 ~ 0.025MPa of negative pressure at 1480 ~ 1500 DEG C, and the dwell time is 10-20 minutes after cast.
Cleared up after cast extremely easily, inner chamber is without scab phenomenon.
Embodiment instead of the form of unselected clay sand mold or resin sand casting manufacture part, simplify casting technique, into
Product rate height can be up to more than 96%, and cost is low, and environmental protection economy.
