Embodiment Construction
[0015] figure 1 Among them, the stepped aluminum alloy oil pan 1 includes a shallow cavity 2 of the stepped aluminum alloy oil pan and a deep cavity 3 of the stepped aluminum alloy oil pan.
[0016] figure 2 Among them, the step-shaped aluminum alloy oil sump casting mold is a semi-metal type and a half-sand type, including a metal type outer mold 4, a sand mold inner mold 9, and a top pouring pouring system. There is a concave part in the metal mold outer mold 4, the sand mold inner mold 9 is placed on the metal mold outer mold 4, and the bottom of the sand mold inner mold 9 is embedded in the concave part of the metal mold outer mold 4, forming a casting in the shape of a stepped aluminum alloy oil pan. type cavity. The inner mold 9 of the sand mold is in the shape of a thin shell, and a set of pouring systems are arranged on both sides of the small step portion 10 and the large step portion 11. The pouring system includes a sprue cup 5, a sprue 6, a runner 7 and an ingat...

The invention discloses a casting method and a special casting mold of a step-shaped aluminum alloy oil sump, the casting mold is semi metal semi sand type, a mold cavity of the step-shaped aluminum alloy oil sump shape is formed by a sand type inner die and a metal type outer die of the casting mold, the mold cavity of the step-shaped aluminum alloy oil sump shape is composed of a small step part and a big step part, top-pouring gating systems are arranged on the sand type inner die, and communicated with the mold cavity, the top-pouring gating systems are two sets, and are respectively arranged at the front end of the small step part and the back end of the big step part, and when in pouring, the production way is as follows: the top-pouring gating system arranged at the front end of the small step part first pours, and the top-pouring gating system arranged at the back end of the big step part delays to pour. According to the casting method, casting moulding is performed in a non-synchronous casting manner by double pouring systems, a gravity casting method and a special casting mold thereof aiming at a step-shaped aluminum alloy oil sump of a relatively small batch are provided, and have the characteristics of economy, good surface quality, high dimensional accuracy and high rate of finished product.
Description
technical field [0001] The invention belongs to the field of casting, and in particular relates to casting of a stepped aluminum alloy oil sump. Background technique [0002] The bottom plane of the step-shaped aluminum alloy oil pan is relatively large, and it is a large thin-walled flat casting. At present, the stepped oil pan with large batches is generally produced by high pressure casting, and the stepped oil pan with small batches is generally produced by sand casting, low pressure casting and gravity metal mold casting. Small batches of stepped aluminum alloy oil pans use high-pressure casting, which is expensive, and small batches are not economical; the dimensional accuracy and surface finish of sand casting products are poor; the bottom plates of products using low-pressure casting and gravity metal casting are prone to shrinkage and cracking. Yield is low. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned...
