Abstract
The utility model discloses a modified casting mold cooling device comprises water annulus (3), need not the direct -cooled water annulus that refrigerated hub window region (1) is corresponding and sets up area segmentation heat dam (4), groove depth 1mm -3mm to with baffle (5) welding shutoff. The utility model discloses make the key cooling wheel spoke of water course regional, has realized the more accurate part of direct -cooled water annulus and executed the cold, simultaneously can be better utilize the advantage that direct -cooled intensity of cooling is big, for the directional solidification of hub creates better distribution of temperature environment, reached elimination casting defects, improve hub quality and production efficiency's purpose.
Description
Technical field
The utility model relates to mould, relates to a kind of low pressure casting die specifically.
Background technology
In Low Pressure Die Casting of Aluminum Wheel Hub field, direct water-cooling technology with its obvious advantage at home and abroad automotive hub enterprise obtain Study and appliance more and more widely.With traditional air-cooled compared with, the obtained Technique of Casting Microstructure of direct-cooled technology is finer and close, and surface state is more excellent, and percentage elongation and intensive properties can obtain and significantly promote.Water channel is directly processed on mould by direct-cooled mode, by the circulation of cooling water, takes away the heat that mould is unnecessary, to realize mould fast cooling and finally to reach the thermally equilibrated state of casting system.Consider from the actual processing and fabricating angle of water channel, what direct Cooling Design nearly all at present all adopted is this water annulus, and its processing is simple, and water pipe is quick for installation; But found by long-term production practices, there is certain drawback in this water channel design, cooling water flow can not be excessive, otherwise be easy to occur casting flaw; Analyzing its reason is: water annulus is except cooling the position of needs cooling, unwanted region is cooled equally, and intensity of cooling is consistent, it can not realize accurate region refrigeration, and this is also exactly exactly the advantage place of traditional air-cooled design.
Therefore, in actual production, want the popularization and application realizing direct-cooled technology, just need to carry out certain improvement to existing, to realize the reasonable cooling of water channel to mould zones of different, create appropriate Temperature Distribution environment, improve comprehensive quality and the production efficiency of wheel hub.
Summary of the invention
The purpose of this utility model is to provide a kind of low pressure casting die cooling device of improvement, this structure can realize needing the die part of cooling to carry out accurately local refrigeration, and don't affect the profiling temperatures of adjacent domain, thus realize the reasonable set of wheel hub, reach elimination defect, improve the quality of products and the object of production efficiency.
The technical solution of the utility model is: for the water channel not needing the foundry goods window region cooled, flume floor arranges heat dam, groove depth 1mm-3mm, and weld shutoff with baffle plate; Though such cooling water is still annular flow, the die part without the need to cooling is carried out effectively separating, has achieved and the specific aim of mould is cooled, more reasonably temperature distribution state can have been formed like this, be beneficial to the consecutive solidification of hub cast.
The utility model advantage is: the direct-cooled channel structure of this improvement effectively solves the excessive drawback of existing water annulus cooled region, the position of mould without the need to cooling has been carried out reasonably dodging, achieve mould more accurate region refrigeration, thus create the Temperature Distribution being more conducive to wheel hub consecutive solidification, ensure that the high-accuracy shaping of foundry goods.
Accompanying drawing explanation
Fig. 1 is the casting mould cooling device schematic diagram of a kind of improvement of the utility model.
Fig. 2 is the schematic diagram of the casting mould cooling device partial enlargement of a kind of improvement of the utility model.
In figure: 1-window region, 2-spoke district, 3-water annulus, 4-heat dam, 5-baffle plate.
Detailed description of the invention
As shown in the figure, the casting mould cooling device of a kind of improvement of the utility model, is made up of water annulus 3, and the direct-cooled water annulus without the need to wheel hub window region 1 correspondence of cooling arranges band segmentation heat dam 4, groove depth 1mm-3mm, and welds shutoff with baffle plate 5.
The utility model is by water channel emphasis cooling spoke region, achieving the more accurate local of direct-cooled water annulus executes cold, can better utilize the advantage that direct-cooled intensity of cooling is large simultaneously, for the consecutive solidification of wheel hub creates better Temperature Distribution environment, reach elimination casting flaw, improve the object of wheel hub quality and production efficiency.
