Abstract
The utility model discloses an aluminum alloy wheel hub die. The die comprises a large die core and a small die core which are oppositely arranged, the large die core is provided with a first drum portion, and the small die core is provided with a second drum portion. The die makes burrs influencing the appearance of a product move downward through the shift of the connection position of the large and small die cores, so the burrs can be conveniently removed by a later-stage processing lathe.
Description
Technical field
The utility model relates to the maching of Al wheel equipment technical field, is specifically related to a kind of mould that can effectively reduce aluminium alloy wheel hub tympanic part burr.
Background technology
At present, in the aluminium alloy wheel hub industry, the product burr mainly is to rely on the later process polishing, reach the purpose of quality assurance, rest on the primitive method that adopts the manual single-piece polishing, so since efficient low, labour intensity large and cost is higher, dust is many during manual polishing.In the prior art, adopt large small mould core to cooperate the Birmasil wheel hub, as shown in Figure 1, big mould core 1 place forms place, blank location, and small mould core 2 is provided with outstanding tympanic part 21, and large small mould core cooperates thus, forms the tympanic part of aluminium alloy wheel hub during casting.Owing in the prior art large small mould core joint portion is set on the big mould core face, the slit of this joint portion can form burr in casting cycle, remove cumbersome during post-production.
The utility model content
The utility model is intended to address the above problem to a certain extent.
Goal of the invention of the present utility model is that the defective that overcomes prior art provides a kind of mould that makes things convenient for post-processed aluminium alloy wheel hub burr.
For achieving the above object, the utility model adopts following technical scheme, a kind of aluminium alloy wheel hub mould, described mould comprises big mould core and the small mould core that is oppositely arranged, be provided with the first tympanic part on the described big mould core, be provided with the second tympanic part on the described small mould core, the position skew that the utility model connects by big or small mould, the burr that affects product appearance is moved down, make things convenient for post-production to remove burr with lathe.
The utility model further improves and is that the chamfering place of the second tympanic part on the described small mould core is circular-arc, further reduces burr.
The beneficial effects of the utility model are,
(1) by the skew of large and small core rod points of engagement, the burr at the outer chamfering of aluminium alloy wheel hub counterdie drum place is moved down;
(2) after the burr of tympanic part moved down, a location in the time of can not affecting metal working and add was easy to the burr that moves down simultaneously processing and disposes.
Description of drawings
Fig. 1 is the fiting relation figure of mould in the prior art.
Fig. 2 is mould fiting relation figure in the utility model.
The specific embodiment
Accompanying drawing only is used for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in the accompanying drawing some known configurations and explanation thereof may to omit be understandable.
Below in conjunction with accompanying drawing, describe structure of the present utility model and principle in detail.
As shown in Figure 2, aluminium alloy wheel hub mould shown in the utility model, this mould comprises big mould core 10 and the small mould core 20 that is oppositely arranged, be provided with the first tympanic part 101 on the big mould core 10, be provided with the second tympanic part 201 on the small mould core 20, form the tympanic part of aluminium alloy wheel hub between big mould core 10 and the small mould core 20.
Better mode is that the chamfering place of the second tympanic part 201 on the described small mould core 20 is circular-arc.
The utility model can make the burr at the outer chamfering of aluminium alloy wheel hub counterdie drum place is moved down by the skew of large and small core rod points of engagement, is convenient to remove in the next procedure this burr.
Describe position relationship in the accompanying drawing and only be used for exemplary illustration, can not be interpreted as the restriction to this patent.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.All any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the utility model claim.
