Abstract
The utility model discloses a die-casting mold, in particular to a motorcycle wheel hub die-casting mold. The utility model provides the motorcycle wheel hub die-casting mold capable of enhancing the molten metal flowing property. The motorcycle wheel hub die-casting mold comprises a fixed mold and a movable mold, wherein a movable mold die cavity and a movable mold slag bag are arranged in the movable mold, the movable mold slag bag is surrounded around the movable mold die cavity, the motorcycle wheel hub die-casting mold also comprises an exhaust block, and the exhaust block is arranged on the movable mold and is positioned on the same parting surface as the movable mold die cavity. After the adoption of the exhaust block, the original air in the die cavity can be easily exhausted after being pressed into the molten metal, so the flowing resistance of the molten metal is reduced, the flowing performance of the molten metal is enhanced, the molten metal can smoothly reach each position of the die cavity, the die casting formed products cannot easily generate defects, and the quality of the product is improved.
Description
Technical field
The utility model relates to a kind of die casting, especially a kind of hub of motorcycle die casting.
Background technology
In die casting was produced, the structure of foundry goods and projected area often were subject to the marginal ability of equipment, and the marginal ability for can better compatible equipment adopts skinny device to produce the production cost that relatively large foundry goods can effectively reduce die casting.
At present when adopting the bigger foundry goods of skinny device production; Because the pressure that little die casting can bear is limited; Therefore when die casting, just can not adopt bigger pressure, less pressure can not guarantee that motlten metal can arrive each corner of mold cavity, and promptly molten metal flow property is relatively poor; This has just caused the border of the die-cast product of producing defective to occur, influences product quality.
The utility model content
The utility model technical problem to be solved provides a kind of hub of motorcycle die casting that increases the motlten metal mobile performance.
The utility model solves the hub of motorcycle die casting that its technical problem adopted; Comprise fixed half and moving half; Be provided with dynamic model die cavity and dynamic model cinder ladle in the said dynamic model; Said dynamic model cinder ladle is looped around around the said dynamic model die cavity, also comprises the exhaust piece, and said exhaust piece is arranged on the said dynamic model and with said dynamic model die cavity and is positioned at same die joint.
Further be, also comprise the guiding sluice way, said guiding sluice way is communicated with said dynamic model cinder ladle and said exhaust piece.
Further be that said exhaust piece is arranged on the both sides up and down of said dynamic model die cavity.
Further be, said exhaust piece is provided with one at the upside of said dynamic model die cavity, is provided with two at the downside of said dynamic model die cavity.
The beneficial effect of the utility model is: after adopting the exhaust piece; Original air just can be discharged after being pressed into motlten metal easily in the die cavity; This has just reduced the molten metal flow resistance, has increased molten metal flow property, thereby makes motlten metal can arrive each position of die cavity smoothly; The product of die cast is not easy to occur defective thus, has increased the quality of product.Between exhaust piece and dynamic model cinder ladle, the guiding sluice way can also be set, thereby make the air in the die cavity better to discharge.The exhaust piece can be arranged on the both sides up and down of said dynamic model die cavity, so just can not stop the side core-pulling operation, is convenient to the entire arrangement of mould.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Parts, position and numbering among the figure: dynamic model 1, dynamic model die cavity 2, guiding sluice way 3, exhaust piece 4, dynamic model cinder ladle 5.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The utility model comprises fixed half and moving half 1; Be provided with dynamic model die cavity 2 and dynamic model cinder ladle 5 in the said dynamic model 1; Said dynamic model cinder ladle 5 is looped around around the said dynamic model die cavity 2, also comprises exhaust piece 4, and said exhaust piece 4 is arranged on the said dynamic model 1 and with said dynamic model die cavity 2 and is positioned at same die joint.Usually the exhaust of mould all utilizes the slit of mould structure to carry out exhaust, and for example exhaust is come in the die joint gap between dynamic model 1 and the cover half, and its exhaust capacity of such exhaust mode is limited.4 need of the exhaust piece of the utility model are arranged on same die joint with dynamic model die cavity 2 and get final product, and can a plurality of exhaust pieces 4 be set according to the complexity of dynamic model die cavity 2 and arrange accordingly, like this in press casting procedure; Motlten metal is after getting into die cavity; Original gas in the die cavity will enter into exhaust piece 4, thereby exhaust has smoothly so just reduced exhaust resistance; Motlten metal just can flow to each corner of die cavity smoothly; When die casting, also need not to adopt bigger pressure, so both realized the big foundry goods of little die production, also guaranteed the quality of producing.
In order better to carry out exhaust, as shown in Figure 1, also comprise guiding sluice way 3, said guiding sluice way 3 is communicated with said dynamic model cinder ladle 5 and said exhaust piece 4.Because dynamic model cinder ladle 5 is around being arranged on around the dynamic model die cavity 2; Therefore the gas that when die casting, overflows in the die cavity will preferentially get into dynamic model cinder ladle 5; Be incorporated into gas in the exhaust piece 4 through guiding sluice way 3 and discharge this moment; So in fact improved the efficient of exhaust, better improved the drainage effect in the die cavity, the product that makes die casting produce has better quality.
Specifically, as shown in Figure 1, said exhaust piece 4 is arranged on the both sides up and down of said dynamic model die cavity 2.Usually die casting can relate to the side core-pulling structure, and therefore, exhaust piece 4 just can be arranged in both sides up and down; Both sides up and down about promptly being with the side core-pulling structure; Just can not hinder the side core-pulling structure in use thus, it is more reasonable that entire die is arranged, when safeguarding, is more prone to.
Concrete, as shown in Figure 1, said exhaust piece 4 is provided with one at the upside of said dynamic model die cavity 2, is provided with two at the downside of said dynamic model die cavity 2.
