Embodiment Construction

[0010] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0011] Depend on figure 1 It can be seen that the present invention includes: a pressure chamber 1; the pressure chamber 1 is divided into two channels; the shape of the two channels is "fan" type, passing through the first sprue 2, the first runner 4 and the second The two sprues 3 and the second runner 5 are connected with the first casting body A and the second casting body B; the first runner 4 divides into five ways and enters the first gate of the first casting body A respectively 6. The second gate 7, the third gate 8, the fourth gate 9 and the fifth gate 10; the second runner 5 is divided into five ways to enter the sixth gate of the second casting body B 11. The seventh gate 12, the eighth gate 13, the ninth gate 14 and the tenth gate 15;...

Abstract

The invention relates to a sprue device of magnesium alloy front-end support pressure castings. The sprue device comprises a pressure chamber and is characterized in that the pressure chamber is divided into two paths; the two paths are each in a fan shape, one path is connected with a first casting body through a first straight pouring gate and a first transverse pouring gate, and the other path is connected with a second casting body through a second straight pouring gate and a second transverse pouring gate; the first transverse pouring gate is divided into five paths to enter a first sprue, a second sprue, a third sprue, a fourth sprue and a fifth sprue of the first casting body correspondingly; and the second transverse pouring gate is divided into five paths to enter a sixth sprue, a seventh sprue, an eighth sprue, a ninth sprue and a tenth sprue of the second casting body correspondingly. The sprue device has the beneficial effects that after the magnesium alloy pressure castings are used for replacing sheet iron stamping parts, the weight is reduced, mechanical performance is not reduced, oil consumption is reduced due to the fact that the weight is reduced, and strength is guaranteed; and production efficiency is improved due to the fact that two products are produced through one mold.

Description

technical field [0001] The invention relates to a magnesium alloy front bracket die casting, in particular to a gate device of the magnesium alloy front bracket die casting. Background technique [0002] In the prior art, the car front bracket is a structural part product, originally using 0.5-0.8mm thin iron sheet stamping parts, because the weight of the thin iron sheet stamping parts is 5kg / piece, so it has an impact on gasoline consumption. [0003] In the prior art, it is changed to a magnesium alloy material for one-time die-casting, with a weight of 2kg / piece. However, the heat capacity of the magnesium alloy material is small, and the thick-walled area where the front bracket is fixed and installed is prone to gas shrinkage or looseness, resulting in a decrease in strength. [0004] Therefore, it is necessary to design a gate device for die castings of magnesium alloy front brackets. Contents of the invention [0005] The technical problem to be solved by the pre...
