Abstract
The invention discloses one kind casting lower die structure, including lower mould body, ceramic insert and lower die briquetting, lower mould body is provided with cell body corresponding with ceramic insert, and the lower die briquetting fixes the ceramic insert.Beneficial effects of the present invention：Using above structure, during casting aluminium alloy wheel hub, make aluminium liquid smoothly full of mold cavity, will also play a part of feeding in blank solidification stages, to obtain the casting of dense internal organization.Mould is not perishable, does not glue aluminium, and more preferably, high temperature resistant is effectively guaranteed the temperature of Feeding channel to heat insulating ability, is the feeding for not influenceing casting after the intensity of cooling at other positions of casting is significantly improved, and production efficiency is improved significantly, and casting quality is obviously improved.
Description
Technical field
The present invention relates to casting technology field, more particularly to a kind of casting lower die structure.
Background technology
Statement in this part merely provides the background information relevant with present disclosure, thereby increases and it is possible to do not constitute
Prior art.
Requirement with the development and each demand business of foundry industry to low pressure casting properties of product and outward appearance is improved constantly,
During casting aluminium alloy wheel hub, just only by spraying, thermal insulation coatings protect mould to traditional mould but thermal insulation coatings easily take off in practice
From, the effect of protection mould is not had, while preventing product from good feeding, properties of product are reduced, and outside cast product
Sight is pulled, and cast product will polish, and cause environmental pollution.
Ceramics have fusing point high, and good heat conductivity, hardness is big, and chemically stable is good, does not hydrolyze, and high-temperature oxidation resistance is good, heat
The coefficient of expansion is small, anti-thermal shock and the advantages of strong chemical resistance, therefore in the fields such as national defence, machinery, chemical industry, metallurgy, electronics tool
There is extensive use, be always the focus of countries in the world material scholar's research.
Therefore prior art has much room for improvement and develops.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind and had both ensured that mould was protected, and also ensures product outsourcing and product
The casting lower die structure of moral character energy.
Technical solution of the invention is：One kind casting lower die structure, including lower mould body, mold insert and lower die briquetting,
Lower mould body is provided with cell body corresponding with mold insert, and the lower die briquetting fixes the mold insert.
Lower mould body material selection H13R or H13 (SKD-61).
Mold insert is formed using composite ceramic material composition sintering.
Lower mould body makes the groove of relative position according to moulding, and the groove in the relative position is tumbled in and meets right by ceramics are ready-made
The part of product structure is answered, then is fixed by lower die briquetting.
The mold insert is composite or the other materials composition with equal benefit.
Beneficial effects of the present invention：Using above structure, during casting aluminium alloy wheel hub, aluminium liquid is set smoothly to fill
Full mold cavity, will also play a part of feeding, to obtain the casting of dense internal organization in blank solidification stages.Mould not by
It is perishable, aluminium is not glued, more preferably, high temperature resistant is effectively guaranteed the temperature of Feeding channel to heat insulating ability, is the cold of other positions of casting
But the feeding of casting is not influenceed after intensity is significantly improved, production efficiency is improved significantly, and casting quality is obviously improved.

Specific embodiment
Embodiment：Refering to Fig. 1 to Fig. 5, the present invention discloses a kind of for wheel hub casting lower die structure, including main body 1, ceramics
Mold insert 2 and lower die briquetting 3, lower mould body 1 according to moulding, make relative position groove or other, in the groove of relative position or other edges
On by ceramics it is ready-made meet the part of corresponding product structure, then be fixed up by lower die briquetting 3 formed edge ceramics lower mould knot
Structure.
Finally realized during casting aluminium alloy wheel hub using said structure, aluminium liquid is smoothly full of mould type
Chamber, will also play a part of feeding, to obtain the casting of dense internal organization in blank solidification stages.Mould is not perishable,
Aluminium is not glued, more preferably, high temperature resistant is effectively guaranteed the temperature of Feeding channel to heat insulating ability, is the intensity of cooling at other positions of casting
The feeding of casting is not influenceed after significantly improving, production efficiency is improved significantly, and casting quality is obviously improved.
Specific method is, according to product-forming structure, the lower mould of casting mould design requirement design casting, the lower mould of casting according to
Product feature is chosen to be needed to do the module of ceramic insert 2.The material selection H13R of lower mould body 1, forges blank, by processing, heat
Treatment etc. processes the lower mould of casting, chooses the position for needing to make ceramics, makes the structure that can fill ceramic insert.Ceramic insert 2 is adopted
Sintered with composite ceramic material composition and form module, then processed by product feature；Connected using insertion or other structures
Connect ceramic insert.Both ensured that mould was protected, also ensured product outsourcing and properties of product.
In the description of this specification, the description of term " one embodiment " etc. means that combining the embodiment or example describes
Specific features, structure, material or feature be contained at least one embodiment of the invention or example.In this manual,
Schematic representation to above-mentioned term is not necessarily referring to identical embodiment or example.And, the specific features of description, knot
Structure, material or feature can in an appropriate manner be combined in one or more any embodiments or example.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
