Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] In the description of the present invention, it should be understood that terms such as "forward", "backward", "front", "rear", "side", etc. indicating orientation or positional relationship are based on the orientation shown in the drawings Or positional relationship is only for the purpose of describing the present invention or simplifying the description, but does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present invention.

[0017] Such as Figure 1 to Figure 2 In the illustrated lost foam casting mold for the axle housing, each movable block of the white mold 2 is sequentially assembled in the pouring cavity formed by the upper mold assem...

Abstract

The invention relates to a full mold casting mold for an axle shell. The full mold casting mold for the axle shell comprises an upper mold assembly, a lower mold assembly and a lost foam pattern assembly which is located in a pouring cavity formed by the upper mold assembly and the lower mold assembly; and a pouring pipe and a plurality of air outlet pipes are arranged on the top of the upper mold assembly. According to the casting mold, a traditional mold core is replaced with a full mold, the requirement of a high-complicated product can be met, the problem that in traditional sand casting, because the sand core size is not accurate or the lower core position is not accurate, the wall thickness of a casting is not uniform is avoided, the pollutant emission amount is small, and investment and the production cost are reduced.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a lost foam casting mold for an axle housing. Background technique [0002] Traditional medium and large castings generally adopt clay sand casting process, which has poor precision and high energy consumption. Most of modern precision casting adopts lost foam casting (also known as solid casting) technology. The above technology is to bond and combine paraffin or foam models similar in size and shape to castings to form model clusters. After brushing and drying refractory coatings, they are buried in Vibration molding in dry quartz sand, pouring under negative pressure, vaporizes the model, liquid metal occupies the position of the model, solidifies and cools to form a new casting method, which has high precision and high efficiency. Lost Foam Casting is a new technology with nearly no allowance and precise molding. This technology does not need to take molds, has no ...
