Inner surface smoothness it is high, substantially reduce Resistance of opening mould, it can make the casting well and casting of big belt wheel die for processing
It makes in the lid of cave and is not provided with pattern draft, solve the problems, such as cannot there is pattern draft when manufacturing big belt wheel using casting method.
Preferably, the feeding-passage includes charging main channel and charging subchannel, the charging main channel and described point
Flow cone connection, the charging subchannel are connected to the charging main channel and casting cave lid.Further, the charging branch is logical
Road and charging main channel vertical connection.In this way, keeping charging subchannel vertical with main channel is fed, can avoid because of casting metal
Liquid directly pours in casting well through charging main channel causes the big belt wheel of casting bad and uneven because of two sides filling, to keep away
There are the quality problems of volume gas or peeling etc in the big belt wheel for exempting from casting.
Preferably, the quantity of the casting well is even number, and pairs of casting well is symmetricly set on the charging
The two sides of main channel.In this way, not only facilitating charging main channel to shunt in casting process, but also mold can be made main logical positioned at charging
The spot temperature variation of road two sides is consistent, facilitates cooling control.
Preferably, it is provided with cooling tube in the moving-mould-core, which includes the cooling branch pipe of spreader and two chargings
Channel cools down branch pipe, and the cooling branch pipe of the spreader is connected to the cooling branch pipe of the feeding-passage, and two feeding-passages
Cooling branch pipe is symmetricly set on the two sides of the charging main channel and, the spreader cooling branch parallel with the charging main channel
The close spreader of pipe is simultaneously vertical with the charging main channel.Further, the cooling branch pipe of the feeding-passage is located at described
Cast the top of cave lid.In this way, using the cooling branch pipe of spreader to the position in big belt wheel die for processing close to spreader
It is cooled down, to charging main channel close in big belt wheel die for processing and casts well using the cooling branch pipe of feeding-passage
Position is cooled down, and then effectively improves cooling effect, and then improves the cold and hot balance quality of the big belt wheel die for processing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cover half core in the utility model big belt wheel die for processing；
Fig. 2 is the structural schematic diagram of the moving-mould-core in the utility model big belt wheel die for processing.
Specific embodiment
In the following, the utility model big belt wheel die for processing is described in detail in conjunction with Fig. 1 and 2.
As illustrated in fig. 1 and 2, the utility model big belt wheel die for processing includes cover half core 1, moving-mould-core 2 and spreader 3.
The top of cover half core 1 is provided with casting well 11, is provided with tooth slot structure on the side wall of the casting well 11.2 gland of moving-mould-core
At the top of cover half core 1, the bottom of moving-mould-core 2 is provided with casting cave lid 21 corresponding with casting 11 position of well.Moving-mould-core 2
Bottom is provided with feeding-passage 22, which is connected to spreader 3 and casting cave lid 21, the i.e. connection of feeding-passage 22 casting
Well 11 and spreader 3.It casts well 11 and casts the roughness of the inner surface of cave lid 21 within Ra0.2.Such big band
Die for processing is taken turns, casting well 11 and the smoothness for the inner surface for casting cave lid 21 are high, substantially reduce Resistance of opening mould
So as to be not provided with pattern draft in the casting well of big belt wheel die for processing and casting cave lid, solve using casting method system
Cannot there are problems that pattern draft when making big belt wheel.Preferably, feeding-passage 22 includes that charging main channel 221 and charging branch are logical
Road 222, charging main channel 221 are connected to spreader 3, charging subchannel 222 connection charging main channel 221 and casting cave lid 21.
Preferably, charging subchannel 222 and charging 221 vertical connection of main channel.In this way, making to feed subchannel 222 and feeding main channel
221 is vertical, can avoid directly pouring in casting well 11 big belt wheel for leading to casting through charging main channel 221 because of casting metal liquid
Because of two sides, filling is bad and uneven, so that the big belt wheel of casting be avoided the quality problems of volume gas or peeling etc occur.It is preferred that
Ground, the quantity of casting well 11 is even number, and pairs of casting well 11 is symmetricly set on the two sides of charging main channel 221.
In this way, not only facilitating charging main channel 221 to shunt in casting process, but also mold can be made to be located at charging 221 two sides of main channel
Spot temperature variation is consistent, facilitates cooling control.Preferably, it is provided with cooling tube in moving-mould-core 2, which includes spreader
Cooling branch pipe (not shown) and the cooling branch pipe 231 of two feeding-passages, the cooling branch pipe of spreader and the cooling branch of feeding-passage
Pipe 231 is connected to, and the cooling branch pipe 231 of two institute's feeding-passages is symmetricly set on the two sides of charging main channel 221 and leads with charging
Channel 221 is parallel, and the cooling branch pipe of spreader is close to spreader 3 and vertical with main channel 221 is fed.Preferably, feeding-passage is cold
But branch pipe 231 is located at the top of casting cave lid 21.In this way, using the cooling branch pipe of spreader to being leaned in big belt wheel die for processing
The position of nearly spreader 3 is cooled down, and is led in big belt wheel die for processing close to charging using the cooling branch pipe 231 of feeding-passage
Channel 221 and the position for casting well 11 are cooled down, and then effectively improve cooling effect, and then improve big belt wheel processing
With the cold and hot balance quality of mold.The surface of cover half core 1 and moving-mould-core 2 is provided with PST permeable formation (not shown), and should
