Abstract
The utility model discloses a low-tension valve body casting mold which comprises a bottom mold, a left side mold, a right side mold and an upper mold, wherein the left and right side molds are detachably arranged on the bottom mold, the upper mold is detachably arranged on the left and right side molds, and a sprue bushing is arranged in the middle of the bottom mold and internally provided with a resistance heater. By adopting a low-tension casting mode to manufacture a valve body, the low-tension valve body casting mold can ensure that the manufactured finished valve is high in size precision, stable in quality, excellent in appearance quality, high in craft product yield, and low in cost; the sprue bushing is arranged in the middle of the bottom mold and communicated with high-temperature metal liquid in a holding furnace and a heating wire is arranged around the sprue bushing, thus being capable of ensuring the temperature of cast solution, and effectively solving the shrinkage cavity and shrinkage porosity defects; and an air cooling channel is arranged on a cavity of the valve body, thus being capable of effectively avoiding the shrinkage cavity, shrinkage porosity defects and the like in pouring process.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of valve body low pressure casting die.
Background technology
The valve body that is applicable to various vehicles adopts the sand mold gravitational casting usually; Its product of producing exists that dimensional accuracy is relatively poor, inherent quality is unstable (qualification rate is very low under pressure integrity test), low, the defect of high cost of product yield, and its presentation quality is also very poor simultaneously.
Therefore be necessary to develop a kind of novel Valve Block Mould, to overcome all disadvantages of sand mold gravitational casting.
The utility model content
In view of this, the purpose of the utility model provides a kind of valve body low pressure casting die, and it has dimensional accuracy height, steady quality, outstanding, the production efficiency advantages of higher of presentation quality.
The utility model valve body low pressure casting die; Comprise bed die, left side mould, right side mould and patrix; Said left side mould and right side mould are arranged on the bed die with detachable mode; Said patrix is arranged on left side mould and the right side mould with detachable mode, and said bed die middle part is provided with sprue bush, is provided with resistance heater in the said sprue bush.
Further, said resistance heater is a heater strip;
Further, the length of said heater strip is 800mm, and power is 2KW;
Further, said patrix is provided with the core of valve body, and said core is provided with the air cooling passage;
Further, also be provided with ejecting mechanism on the said patrix.
The beneficial effect of the utility model: the utility model valve body low pressure casting die, adopt the low pressure casting mode to make valve body, finished size precision height, the steady quality that can guarantee to make, presentation quality is outstanding, product yield is high, the while is with low cost; This mould is provided with sprue bush at the middle part of bed die, in sprue bush and the holding furnace high-temperature liquid metal communicate and sprue bush around have heater strip, the temperature of the liquation that can guarantee to cast can effectively solve shrinkage cavity, shrinkage defect; This mould offers the air cooling passage on the core of valve body, can effectively avoid in casting process, occurring defectives such as shrinkage cavity, shrinkage porosite.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.

The specific embodiment
Fig. 1 is the perspective view of the utility model valve body low pressure casting die; Fig. 2 is the perspective view of sprue bush; Fig. 3 is the valve body core perspective view that is arranged on the patrix.
As shown in the figure; Present embodiment valve body low pressure casting die; Comprise valve bed die 1, left side mould 2, right side mould 3 and patrix 4, said left side mould 2 is arranged on the bed die 1 with detachable mode with right side mould 3, and said patrix 4 is arranged on left side mould 2 and the right side mould 3 with detachable mode; Said bed die 1 middle part is provided with sprue bush 5, is provided with resistance heater 6 in the said sprue bush 5.The total resistance heater 6 of present embodiment is a heater strip, in practical implementation, also can adopt the resistance heater of other shapes certainly.
The length of the heater strip in the present embodiment is 800mm, and power is 2KW, the temperature of the liquation that can guarantee to cast.
As the improvement to this embodiment, said patrix 4 is provided with the core 7 of valve body, and said core 7 is provided with air cooling passage 8; Aborning, the air inlet 9 of air cooling passage 8 connects 0.4-0.6MPa compressed air, the gas outlet 9 and the atmosphere of air cooling passage 8.
In the present embodiment, also be provided with ejecting mechanism 10 on the said patrix 4.
The mould assembling action of the utility model valve body low pressure casting die: bed die 1 is fixed, closes earlier left side mould 2, right side mould 3 successively, and mould again closes.
The die sinking action of the utility model valve body low pressure casting die: open earlier left side mould 2, right side mould 3 successively, open patrix 4 again, product rises to certain height with patrix 4, and the ejecting mechanism 10 that is arranged on the patrix 4 just leaves mould with the product top.
The utility model valve body low pressure casting die adopts the low pressure casting mode to make valve body, and finished size precision height, the steady quality that can guarantee to make, presentation quality is outstanding, product yield is high, the while is with low cost; This mould is provided with sprue bush at the middle part of bed die, in sprue bush and the holding furnace high-temperature liquid metal communicate and sprue bush around have heater strip, the temperature of the liquation that can guarantee to cast can effective solution shrinkage cavity, shrinkage defect; This mould offers the air cooling passage on the core of valve body, can effectively avoid in casting process, occurring defectives such as shrinkage cavity, shrinkage porosite.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
