Described the first cross gate is totally semicircle, the middle part of described sprue in semicircle the first cross gate, and two the first ingate sprue gates of described the first cross gate end are divided in gear box first half both sides.
Described the second cross gate is two formation V fonts, and two the second ingate sprue gates of the second cross gate end are in thick large part place, gear box bottom.
The cross section of described the first cross gate, the second cross gate is trapezoidal, and wherein, the end of the first cross gate trapezoid cross section is 2.6: 1 with the ratio of height; At the bottom of the second cross gate trapezoid cross section, it is 0.73: 1 with the ratio of height.
Described the first ingate sprue gate, the second ingate sprue gate are truncated cone-shaped, and the intracavity section at truncated cone-shaped sprue gate gradually becomes, and molten metal flows into end, and to flow out end cross-sectional area ratio with molten metal be 2.25: 1.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Filling time of the present invention is shorter, because running gate system of the present invention is step gating system, the first cross gate, the second cross gate are divided into two-layer up and down, molten metal bath divides two-layer injection cast model by the first cross gate sprue gate, the second cross gate sprue gate, filling time shortens, and thermal loss reduces.Because the present invention is step gating system, the first cross gate is provided with sprue gate in the both sides of the gear box first half, can reduce casing top shrinkage porosite shrinkage cavity defect; Two sprue gates of the second cross gate are distributed in thick large part place, gear box bottom, and its sectional dimension is larger, can well to bottom half, easily produce shrinkage porosite shrinkage cavity position and carry out feeding effect, greatly reduce shrinkage porosite shrinkage cavity defect, effectively improve casting quality.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention; Fig. 2 is gear box structural representation; Fig. 3 is application state schematic diagram of the present invention.
Number in the figure: 1 cup, 2 sprues, 3 first cross gates, 31 first ingate sprue gates, 4 second cross gates, 41 second ingate sprue gates, 5 gear boxes.
Below pass through the specific embodiment, and the invention will be further described by reference to the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1-3, the evaporative pattern running gate system of gear box of the present invention, on sprue 2, be communicated with successively from top to bottom cup 1, the first cross gate 3 and the second cross gate 4, the first cross gates 3 and the second cross gate 4 separately along the radial communication of sprue on sprue 2; And, at the first cross gate, the second cross gate, away from the end of sprue, be respectively equipped with the first ingate sprue gate 31, the second ingate sprue gate 41.
In specifically arranging, the first cross gate 3 be totally semicircle, the middle part of sprue in semicircle the first cross gate, and 31 points, two first ingate sprue gates of the first cross gate end are in gear box 5 first half both sides.
The second cross gate is two and the formation V font that length is different, and two the second ingate sprue gates 41 of the second cross gate end are in thick large part place, gear box bottom.
The cross section of the first cross gate 3, the second cross gate 4 is trapezoidal, and wherein, the end of the first cross gate trapezoid cross section is 2.6: 1 with the ratio of height; At the bottom of the second cross gate trapezoid cross section, it is 0.73: 1 with the ratio of height.
The first ingate sprue gate 31, the second ingate sprue gate 41 are truncated cone-shaped, and the intracavity section at truncated cone-shaped sprue gate gradually becomes, and molten metal flows into end, and to flow out end cross-sectional area ratio with molten metal be 2.25: 1.
In concrete application, when molten metal bath is flowed through step gating system of the present invention, molten metal bath flows into the first cross gate 3, the second cross gate 4 by sprue 2, and inject cast model by sprue gate separately, and filling time is shorter, and thermal loss reduces greatly, molten metal maintains good mobility, avoid the too early appearance of cold burden, can control preferably the molten metal temperature entering in die cavity, greatly improve casting quality.The first cross gate 3 and the second cross gate 4 have sufficient length the mobile direction of molten metal are controlled, and the first cross gate, the second cross gate are isolated mutually, are not interfere with each other, can effectively prevent that molten metal from forming turbulent flow, avoid in molten metal, being mingled with gas, and then effectively avoid foundry goods to produce shrinkage cavity.The cross sectional shape of the first cross gate 3, the second cross gate 4 is trapezoidal, because of the cross gate molten metal thermal loss of trapezoid cross section little, easy to process.And in the present invention, the second cross gate 4 sectional dimensions are greater than the sectional dimension of the first cross gate 3, can well to bottom half, easily produce shrinkage porosite shrinkage cavity position and carry out feeding, greatly reduce shrinkage porosite shrinkage cavity defect, improve casting quality.
