At present, for discoid foundry goods running gate system as shown in Figure 1: comprise pouring basin 1, straight channel 2, runner 3, ingate 4, die cavity 5, mould 6, cinder ladle 7 and exhaust duct 8, described ingate 4 is one, be arranged on the axis direction of straight channel 2, and ingate 4 is right angle (as shown in Figure 2) with the angle a of die cavity 5 lateral wall, molten metal pours in die cavity 5 by ingate 4 with the right angle flow direction, so that cause kinetic energy and thermal loss larger, and be easily mixed into air, cause volume gas or inspiratory phenomenon, cause interiors of products pore many, product wall is coarse, die wear is serious, in addition, ingate 3 and the junction cutting of die cavity 5 difficulty of polishing is larger, not only affect product percent of pass, and have a strong impact on production efficiency and mold use life-span.
Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of running gate system for discoid foundry goods, to improve the product percent of pass of discoid foundry goods and to extend the mold use life-span.
For achieving the above object, the utility model adopts following technical scheme:
A kind of running gate system for discoid foundry goods, comprise pouring basin, straight channel, runner, ingate, die cavity, mould, cinder ladle and exhaust duct, it is characterized in that: between straight channel and runner, be provided with crossing current road, lightening hole is provided with at the axis direction in crossing current road, described ingate is two fan gates, is symmetricly set on the both sides of described lightening hole.
As a kind of embodiment, described running gate system comprises a pouring basin, straight channel, two crossing current roads, the one end in each crossing current road and described straight channel vertical connection, lightening hole is equipped with at the axis direction in each crossing current road, all be symmetrically arranged with two ingates in the both sides of described lightening hole, described ingate is connected with die cavity.
Preferably, the angle of described ingate and die cavity lateral wall is obtuse angle.
As further preferred version, the angle of described ingate and die cavity lateral wall is 155 ~ 165 degree.
Compared to prior art, Advantageous Effects of the present utility model is:
Adopt the running gate system that the utility model provides, kinetic energy and thermal loss can be reduced, effective minimizing volume gas or inspiratory phenomenon, the distance that molten metal can be made to arrive each position of die cavity from ingate is close, fill type flow process the shortest, avoid the many defects flung existing for die cavity of the prior art, make interiors of products pore be improved significantly, product percent of pass can improve 20% ~ 30%, especially the wearing and tearing to mould can be reduced, the mold use life-span can be made to bring up to 60,000 moulds by 1.5 ten thousand moulds, production efficiency is not only made to be improved significantly, and make production cost obtain conspicuousness reduction, relative to prior art, there is conspicuousness progress.
