Description
Technical field
The utility model is related to apparatus for casting field, specifically a kind of casting mould.
Background technology
In the casting process such as low pressure casting, counter-pressure casting, suction pouring, impurity is inevitably contained in topping, such as
Fruit impurity is entered in mold cavity, will form product dreg defect, influences properties of product and presentation quality.Therefore, exist
Before topping flows into spreader from the cast gate of bed die, by filter device, can so that topping flow velocity uniformly, steady, not volume gas, guarantor
Demonstrate,proving product has good purity and quality.
At present, common filter device is the filter screen of ceramic matrix.In use, due to ceramic matrix hardness compared with
Greatly, there is larger brittleness, after being contacted with the spreader and bed die of hard, ceramic matrix is easily broken up, and broken foam easily follows
Topping is flowed into mold, cannot not only be filtered the slag in topping, be generated additional ceramic slag in topping instead, seriously affect
Filter effect can not ensure product purity and quality.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of casting mould, can solve existing casting
The problem of filter device effect is bad during making, product purity is not high and quality is relatively low.
To achieve the above object, technical solution is as follows used by the utility model：Note including bed die, on bed die
Cast gate and the spreader above note cast gate, note and have been sequentially placed rigid filter net and flexible filter between cast gate and spreader
Net, it is online that spreader is pressed on flexible filter.
Flexible filter net is arranged between rigid filter net and spreader, avoids rigid filter by above-mentioned casting mould
Net is in direct contact the waste residue generated after collision with hard spreader, and flowing into molding die influences product quality, so as to improve production
The purity and quality of product.Flexible filter net and rigid filter net form dual filtering structure, further improve inflow shaping mould
The purity of topping after tool.
Wherein, above-mentioned flexible filter net is carbon fiber filter net.
Wherein, above-mentioned flexible filter net is metal filter screen.
Above-mentioned flexible filter net uses carbon fiber or metal material, has certain elasticity, in hard spreader and rigidity
Buffering transitional function is played in filter screen.Meanwhile above-mentioned material has certain hardness, easy knitting forming is filtered in topping
Impurity.Further, which has higher fusing point, and after ensure that topping flows through flexible filter net, flexible filter net is not
It can fail because of the temperature of topping.
Wherein, above-mentioned rigid filter net is ceramic matrix filter screen.
Above-mentioned rigid filter net uses ceramic matrix material, has stronger adsorptivity performance.
