Abstract
The utility model discloses a kind of vermicular cast iron brake drum running gate system, comprise the sprue longitudinally arranged, the left and right sides, sprue lower end is respectively equipped with left bend pipe, right straight tube, left bend pipe, right straight tube are provided with filter screen near sprue junction, left bend pipe, right straight tube end are communicated with cross gate, cross gate be multiple tracks spaced apart and mutually the semi-circular groove of UNICOM form, cross gate is linked with multiple tracks ingate spaced apart, and ingate pushes down the edge of vermicular cast iron brake drum.The utility model adopts the mode of dispersion thermal center to arrange pouring technology, extends cross gate length, arranges many to ingate, utilize three dimensional design running gate system, by simulation, according to molten iron by ingate quantity, change cross gate area of section, thus realize each ingate and enter the amount of molten iron and the uniformity of time, accomplish that product heats unanimously everywhere, spread heat, realizes heat energy-saving position and solidifies simultaneously, avoid the appearance of product shrinkage cavity and porosity, realize the object of producing premium casting.
Description
technical field:
The utility model relates to the casting of automobile brake drum product, particularly relates to a kind of vermicular cast iron brake drum running gate system.
background technology:
Vermicular cast iron shrinkage porosite tendency is between spheroidal graphite cast-iron and casting pig, and current employing method mainly arranges or do not arrange rising head, and cross gate is shorter, through test, to this series products, due to structure restriction, batch production on production, rising head is difficult to realize feeding, and product exists shrinkage cavity and porosity in various degree.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of vermicular cast iron brake drum running gate system, according to molten iron by ingate quantity, change cross gate area of section, thus realize each ingate and enter the amount of molten iron and the uniformity of time, accomplish that product heats unanimously everywhere, spread heat, realize heat energy-saving position to solidify simultaneously, avoid the appearance of product shrinkage cavity and porosity, realize the object of producing premium casting.
The technical solution of the utility model is as follows:
Vermicular cast iron brake drum running gate system, it is characterized in that: comprise the sprue longitudinally arranged, the left and right sides, sprue lower end is respectively equipped with left bend pipe, right straight tube, left bend pipe, right straight tube are provided with filter screen near sprue junction, left bend pipe, right straight tube end are communicated with cross gate, cross gate be multiple tracks spaced apart and mutually the semi-circular groove of UNICOM form, cross gate is linked with multiple tracks ingate spaced apart, and ingate pushes down the edge of vermicular cast iron brake drum.
Described vermicular cast iron brake drum running gate system, is characterized in that: the quantity of described cross gate is 2 ~ 12 roads, and the outer wall of cross gate is also provided with metallographic test block.
Described vermicular cast iron brake drum running gate system, is characterized in that: the inwall of described vermicular cast iron brake drum is provided with the air-out needle along annular spread.
Described vermicular cast iron brake drum running gate system, is characterized in that: the quantity of described ingate is 4 ~ 12 roads, and the two ends of ingate are flare.
The utility model has the advantages that:
The utility model novel in structural design, adopts the mode of dispersion thermal center to arrange pouring technology, extends cross gate length, arrange and arrive ingate more, utilize three dimensional design running gate system, by simulation, according to molten iron by ingate quantity, change cross gate area of section, thus realize each ingate and enter the amount of molten iron and the uniformity of time, accomplish that product heats unanimously everywhere, spread heat, realize heat energy-saving position to solidify simultaneously, avoid the appearance of product shrinkage cavity and porosity, realize the object of producing premium casting.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
See accompanying drawing:
Vermicular cast iron brake drum running gate system, comprise the sprue 1 longitudinally arranged, the left and right sides, sprue 1 lower end is respectively equipped with left bend pipe 2, right straight tube 3, left bend pipe 2, right straight tube 3 are provided with filter screen 4 near sprue junction, left bend pipe 2, right straight tube 3 end are communicated with cross gate 5, cross gate 5 be multiple tracks spaced apart and mutually the semi-circular groove of UNICOM form, cross gate 5 is linked with multiple tracks ingate spaced apart 6, and ingate 6 pushes down the edge of vermicular cast iron brake drum 7.
