Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1, a kind of gray cast iron running gate system, including be sequentially communicated pouring basin 1, sprue 2, the first running channel 3,
Second running channel 4, third running channel 5, the 4th running channel 6, ingate component 7 and casting type chamber 8, pouring basin 1 have sprue 2, directly
The first running channel 4 is communicated with below running channel 2, sprue 2 and the first running channel 4 are vertical setting, between the first running channel 4 and sprue 2
Equipped with filter 3, third running channel 5 is circumferentially positioned at 4 outside of the second running channel, and the 4th running channel 6 is circumferentially positioned at outside third running channel 5
Side, ingate group 8 include multiple ingates 81, and the 4th running channel 7 is connected to by multiple ingates 81 with casting type chamber 9.
In addition, the second running channel 5 is the running channel of 1/4 chondritic.
