Abstract
The utility model relates to a high-scale open-type gating system for an aluminum alloy casting. The high-scale open-type gating system comprises a gating system consisting of a pouring cup, a sprue, a cross gate, an ingate and a casting, wherein a communication position between the sprue and the cross gate is provided with a buffering pit; the sprue is arranged in the middle part of the cross gate; the cross gate is of an integrated structure that an upper cross gate and a lower cross gate are communicated end to end up and down; the sprue is arranged at the upper part of the lower cross gate in the middle of the cross gate; a ratio of the cross section area S2 of the cross gate to the cross section area S1 of the sprue is not less than 2; and a ratio of the cross section area S3 of the ingate to the cross section area S2 of the cross gate is not less than 1.7. According to the high-scale open-type gating system, the defect of slag inclusion of the casting is overcome, and impact of molten aluminum alloy on a cavity is reduced when the molten aluminum alloy is injected into the cavity, so that sand is prevented from entering the casting; and the high-scale open-type gating system is beneficial to preventing included slag in the molten aluminum alloy from entering the casting, reducing the casting cost and improving the casting reliability and pass percent of the casting.
Description
Technical field
The utility model belongs to the running gate system technical field of aluminium alloy castings, is specifically related to a kind of vast scale unchoked running system that is applied to aluminium alloy castings.
Background technology
Aluminium alloy castings adopts the sand mold gravity foundry technology very general at home; Running gate system has important effect to casting quality; The high-voltage switch gear product is used aluminium alloy castings, and the overwhelming majority all can adopt sand mold-gravity foundry technology, and the running gate system of foundry goods is very crucial; Directly influence many casting flaws such as pore, slag inclusion, shrinkage cavity shrinkage porosity of foundry goods, and the ratio design of the sprue of running gate system, cross gate, ingate is also relatively more chaotic.
Summary of the invention
The purpose of the utility model is to solve the problem that exists in the prior art and a kind of aluminium alloy castings that is applied to is provided, and can solve the vast scale unchoked running system of the aluminium alloy castings of foundry goods slag inclusion problem.
The technical scheme of the utility model is achieved in that a kind of vast scale unchoked running system of aluminium alloy castings; Comprise the running gate system that cup, sprue, cross gate, ingate and foundry goods constitute; Sprue is communicated with the position and has the buffering nest with cross gate; Sprue is arranged on the middle part of cross gate; Described cross gate is connected to end up and down by mo(u)ld top half cross gate and mo(u)ld bottom half cross gate and constitutes integrative-structure, and this mo(u)ld top half cross gate is arranged on the top of mo(u)ld bottom half cross gate, and described sprue is arranged on the mo(u)ld bottom half cross gate top in the middle of the cross gate.
Described ingate is separately positioned on the mo(u)ld bottom half cross gate at cross gate both ends.
The ratio of the cross-sectional area S2 of described cross gate and the cross-sectional area S1 of sprue is not less than 2, and the ratio of the cross-sectional area S2 of the cross-sectional area S3 of ingate and cross gate is not less than 1.7.
The cross section of described sprue is round-shaped.
The good effect of the utility model:
By former explained hereafter, be difficult to prevent the defective of foundry goods slag inclusion class in the past, and after this technology enforcement, prevented the defective of foundry goods slag inclusion, when aluminum alloy melt injects die cavity, reduced the impact of aluminum alloy melt, in order to avoid sand gets into foundry goods to die cavity; Help preventing that the slag inclusion in the aluminum alloy melt from getting into foundry goods; Reduce the casting cost, improve foundry goods reliability and casting qualified rate.

The specific embodiment
As shown in Figure 1; The 8P3.148.036 cylinder body aluminium alloy castings of ZF12-126 (L) product that the diagram foundry goods is used for the high-voltage switch gear industry; The utility model comprises the running gate system that cup 1, sprue 2, cross gate 3, ingate 4 and foundry goods 5 constitute; Sprue 2 is communicated with the position and has buffering nest 6 with cross gate 3; Sprue 2 is arranged on the middle part of cross gate 3, and described cross gate 3 is connected to end up and down by mo(u)ld top half cross gate 7 and mo(u)ld bottom half cross gate 8 and constitutes integrative-structure, and this mo(u)ld top half cross gate 7 is arranged on the top of mo(u)ld bottom half cross gate 8; Described sprue 2 is arranged on the mo(u)ld bottom half cross gate top in the middle of the cross gate 3, and ingate 4 is separately positioned on the mo(u)ld bottom half cross gate at cross gate 3 both ends.The ratio of the cross-sectional area S2 of cross gate 3 and the cross-sectional area S1 of sprue 2 is not less than 2, and the ratio of the cross-sectional area S2 of the cross-sectional area S3 of ingate 4 and cross gate 3 is not less than 1.7.The cross section of sprue 2 is round-shaped.
According to the difference of running gate system medium casting structure, the ratio of the sectional area of the ratio of the sectional area of its cross gate and the sectional area of sprue, the sectional area of ingate and cross gate is also different.
