A kind of side pressure core casting process of side wall outer cover of automobile mould

Abstract

The invention discloses a side pressure core casting process for an automobile mould's side wall and outer cover. A base matched with the model is provided to fix and place the model to locate three reference planes of XYZ, so as to improve the deformation control of subsequent casting; From the EPS foam model machining stage, the method control of model forming deformation detection, to the process quality control, so that the body deformation detection after unboxing and forming of castings, and machining are solved. Under the control of this process, the problem of single The deformation control of slender castings is remarkable.

Description

technical field [0001] The invention relates to the technical field of automobile castings, in particular to a side pressure core casting process for an automobile mold side wall outer cover. Background technique [0002] At present, in the production of automobile molds, especially the side wall castings, long side pressure cores are used to shape the door frame. This part plays the role of flanging and shaping in the car side wall mold, which directly affects the appearance quality of the car door frame. The side press core has a special structure, which is thin, long, single-structured, and the end is suspended without plane support. It is easy to deform during the production process of the lost foam. At present, there is no deformation control in the production process of this kind of side press core in the industry. It is a very good and effective method, which has a great impact on the quality control of the casting box and product molding process. [0003] Thin model...

[0002] At present, in the production of automobile molds, especially the side wall castings, long side pressure cores are used to shape the door frame. This part plays the role of flanging and shaping in the car side wall mold, which directly affects the appearance quality of the car door frame. The side press core has a special structure, which is thin, long, single-structured, and the end is suspended without plane support. It is easy to deform during the production process of the lost foam. At present, there is no deformation control in the production process of this kind of side press core in the industry. It is a very good and effective method, which has a great impact on the quality control of the casting box and product molding process.

[0003] Thin models generally have a length of about 3000mm, a width of only about 400mm, and a height of 600-700mm. This kind of thin model is easily deformed during the casting stage, and the model does not have a uniform reference plane. It is very difficult, the deformation of castings in the later period exceeds the tolerance range, and there is a risk of scrapping. Therefore, it is particularly important to solve such problems
