Abstract
The utility model discloses a kind of for 465Q motor cylinder block casting mold, comprise pouring basin, sprue, cross gate and ingate; Pouring basin is that infundibulate accepts outside molten metal of toppling over, and sprue connects pouring basin and cross gate and molten metal is introduced casting mold inside; Cross gate connects sprue and distributes molten metal, and cross gate is two; Ingate connects cross gate and inculcates molten metal to casting mold die cavity; This utility model scheme due to cross gate cross section large, molten metal flow velocity in cross gate reduces, and makes liquid alloy steadily be full of casting mold, not impingement wall and core, does not produce eddy current splash, and non-involvement gas is conducive to outside the air in die cavity and other gas discharge types, stop that field trash enters die cavity, and running gate system is simple, account for sandbox machine long-pending few, volume is little, be conducive to reducing rising head volume, save aluminium alloy and molding sand, improve sandbox utilization rate, facilitate moulding.
Description
Technical field
The utility model relates to a kind of motor cylinder block casting mold, especially for a kind of casting mold being applied to 465Q motor cylinder block.
Background technology
Casting system is for liquid metal being introduced casting mold die cavity and the passage offered in casting mold, comprising: the sprue cup cup 1. accepting molten metal, also claim pouring basin; 2. pouring basin and runner gate is connected, by molten metal by the sprue introducing casting mold inside outside casting mold; 3. the cross gate that sprue distributes molten metal is connected; 4. molten metal inculcated by ingate from cross gate to casting mold die cavity is connected;
The speed that running gate system controls molten metal filling casting mold and the time be full of needed for casting mold, molten metal is made to enter casting mold reposefully, avoid turbulent flow and washing away casting mold, slag and other field trashes are stoped to enter die cavity, non-involvement gas during cast, and the principle meeting consecutive solidification when making foundry goods cool as far as possible.Wherein, the total sectional area of the total sectional area of ingate, the total sectional area of runner gate and down gate is the important parameter of running gate system.Different according to the ratio of the respective total sectional area of ingate, runner gate, down gate, running gate system is divided into open, closed, semi-enclosed three kinds.The runner gate of unchoked running system or the total sectional area of down gate are less than the total sectional area of ingate, and in casting process, molten metal can not be full of running gate system completely, and this running gate system only adopts at special process.The runner gate of positive-pressure gating system or the total sectional area of down gate are greater than the total sectional area of ingate, and after cast starts, whole running gate system is filled with molten metal soon, are conducive to stoping slag and field trash to enter die cavity.Semiclosed running gate system is that sprue discharge area is less than cross gate sectional area summation, but is greater than ingate sectional area summation, and this type of running gate system is more much smaller than positive-pressure gating system to washing away of casting mold, and pushing off the slag effect is then good than open.
The mould adopted when present 465Q motor cylinder block is produced is divided in running gate system: ingate 4 (S1 represents ingate sectional area), cross gate 4 (S2 represents cross gate sectional area), sprue 1 (S3 represents sprue sectional area), present running gate system situation is S2>S1>S3, close to unchoked running system running gate system principle, do not meet the design principle of middle-size and small-size casting moulding system, product is easy to occur cold shut defects and product yield is lower.
Utility model content
In order to reduce 465Q motor cylinder block cold shut defects, improve the product yield of product, the utility model provides a kind of casting mold for 465Q motor cylinder block, comprises the sprue cup accepting molten metal; Connect pouring basin and cross gate, molten metal is introduced the sprue of casting mold inside; Connect the cross gate that sprue distributes molten metal; Connect molten metal inculcated by ingate from cross gate to casting mold die cavity, and cross gate is two.
Further, the ingate that connection cross gate inculcates molten metal to casting mold die cavity is at least 2.
For the drawback of the casting mold of existing 465Q motor cylinder block, adopt the method reducing cross gate area, reduce 2 cross gates and water inlet, make cross gate cross-sectional area S2> sprue cross-sectional area S3> ingate cross-sectional area S1, meet the design principle of enlarged running system, pouring pressure increases, molten iron can quick and stable be full of die cavity, be applicable to the production of middle-size and small-size foundry goods, cold shut defects is reduced to 0 by 5% ~ 10%, cast qualification rate brings up to about 99% by about 85%, product yield brings up to 88.67% by 84.25%, save production cost.

Detailed description of the invention
The utility model is a kind of for 465Q motor cylinder block casting mold, comprises pouring basin, sprue, cross gate and ingate.Pouring basin is that infundibulate accepts outside molten metal of toppling over, and sprue connects pouring basin and cross gate and molten metal is introduced casting mold inside; Cross gate connects sprue and distributes molten metal, and cross gate is two; Ingate connects cross gate and inculcates molten metal to casting mold die cavity.Further design, the ingate that connection cross gate inculcates molten metal to casting mold die cavity is at least two.
To the transformation of 465Q motor cylinder block casting mold, at original two ingates and two cross gates that remove sprue offside in base plate core mold, feed liquor mode is made to change into and enter die cavity for entering die cavity from four ingates from two ingate positions.After original 465Q motor cylinder block removes 2 ingates, remaining sectional area is S1 is 278.4mm
2, after removing two cross gates, remainder crosses water cross-sectional area S2 is 720mm
2, sprue is crossed water sectional area S3 and is become 452mm
2.After transformation, cross gate sectional area S2> sprue sectional area S3> ingate sectional area S1, meets the enlarged running system design principle of middle-size and small-size foundry goods.
Adopt this utility model scheme, choked flow cross section is maximum in cross gate cross section, and in cast, running gate system can be full of, and has certain pushing off the slag ability.Because cross gate cross section is large, molten metal flow velocity in cross gate reduces, and makes liquid alloy steadily be full of casting mold, not impingement wall and core, do not produce eddy current splash, non-involvement gas is conducive to, by outside the air in die cavity and other gas discharge types, stopping that field trash enters die cavity.And running gate system is simple, account for sandbox machine long-pending few, volume is little, is conducive to reducing rising head volume, saves aluminium alloy and molding sand, improve sandbox utilization rate, facilitates the manufacture of moulding, cleaning and running gate system apperance.
