Description
Technical Field
The utility model relates to an area water-cooling technical field of aluminum alloy low pressure casting mould specifically is an aluminum alloy low pressure casting mould with regional water-cooling structure.
Background
Along with the development requirement of light weight of automobiles, more and more aluminum alloy products are developed and adopted. According to different structural characteristics of the aluminum alloy product, certain parts can generate heat junctions in the casting process, so that casting defects such as shrinkage porosity, shrinkage cavity and the like can be formed. The traditional method is feeding with a riser. However, riser feeding has disadvantages, which not only greatly reduce the process yield, but also can prevent some locations from feeding by risers due to structural reasons. For this purpose, we propose a low-pressure casting die of aluminum alloy with a zone water-cooling structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an aluminum alloy low pressure casting mould with regional water-cooling structure to solve the problem that provides among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an aluminum alloy low pressure casting mould with regional water-cooling structure, includes inserts, be equipped with on the mould body with insert matched with recess, insert and fix in the recess, be equipped with the water conservancy diversion pipeline in inserting, and insert one side that is located mould body edge and be equipped with the end of intaking and go out the water end with the water conservancy diversion pipeline intercommunication, it all is connected with the water pipe on end and the play water end to intake.
Preferably, the two ends of the insert are provided with cooling ends communicated with the flow guide channel.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a foundry goods of regional water-cooling structure mould production, foundry goods appearance quality is good, and tissue and mechanical properties are reliable and stable, and the rejection rate reduces, and the rising head feeding is efficient, and the foundry goods yield is high.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an aluminum alloy low pressure casting mould with regional water-cooling structure, includes 1 of inserting, be equipped with on the mould body with insert 1 matched with recess 2, 1 of inserting is fixed in recess 2, be equipped with the water conservancy diversion pipeline in 1 of inserting, and insert 1 one side that is located mould body edge and be equipped with the end 3 and the play water end 4 of intaking with the water conservancy diversion pipeline intercommunication, all be connected with water pipe 5 on the end 3 of intaking and the play water end 4.
The principle of water cooling of the die area is as follows:
normal temperature water flows in from the water inlet end 3 and flows out from the water outlet end 4, and the water circulates to take away the temperature of the area on the die through water flow, so that the aim of water cooling of the area is fulfilled.
And the two ends of the insert 1 are provided with cooling ends 6 communicated with the flow guide channel, so that the cooling effect is improved.
If casting defects such as shrinkage cavities, shrinkage porosity, air holes, slag holes and the like exist in the casting product, the defects can become stress sources in subsequent use, the mechanical property and the service life of the casting can be greatly reduced, and the casting can fail in advance in the service process. It has therefore been a goal of foundries to strive for defect-free castings.
In the aluminum alloy casting, the local area water cooling is adopted for the place where the hot spot is generated in the solidification process, the heat of the hot spot part is rapidly taken away by the flowing of circulating water, so that the hot spot part is rapidly cooled and solidified, and a casting is cooled to have a good temperature gradient. The chilled part of the casting has compact structure and no casting defects from the metallographic structure, thereby ensuring the due mechanical property and service life of the material.
With one configuration, an insert 1 is designed to correspond to the hot spot of the casting, and the mold is locally cooled by circulating fluid (typically water) in the insert 1.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
