Embodiment Construction

[0018] The present invention will be further described below.

[0019] A kind of mold casting method of automobile cover part of the present invention, comprises the following steps:

[0020] (1) The polystyrene foam model of the required shape and size processed by CNC milling machine;

[0021] (2) After weighing the polystyrene foam model, estimate the weight of the mold insert, paint and prepare the sand-making box;

[0022] (3) Use 40-60 mesh molding sand, tamp the sand, pierce the air holes on the sand mold, CO 2 Gas blowing for 8 minutes to fully harden the molding sand;

[0023] (4) Use molding sand to make the upper box, pierce air holes on the compacted molding sand, and then blow CO 2 Gas for 8 minutes, until the molding sand is fully hardened;

[0024] (5) Add pig iron, scrap steel, ferrochrome, ferromanganese, ferromolybdenum, ferrovanadium, and ferrosilicon to a 200 kg induction furnace to melt for 55 minutes in turn, then use a slag accumulator to gather slag...

Abstract

The invention relates to a casting method for an automobile covering part mold. The casting method comprises the following steps: (1) machining a mold; (2) estimating the weight of a mold insert afterweighing the mold, brushing a coating, and preparing a sand making box; (3) using 40-60-mesh molding sand, ramming and tamping the molding sand, and stabbing pores on the sand mold; (4) making an upper box by using the molding sand till the molding sand is fully hardened; (5) adding pig iron, steel scrap, ferrochromium, ferromanganese, ferromolybdenum, ferrovanadium and silicon iron into a 200kginduction furnace to be melted, carrying out drossing, carrying out deoxidation by pure aluminum, carrying out tapping and lip-pouring of a ladle, and carrying out pouring and cooling to obtain a near-net-shape casting; and (6) after pouring, carrying out knockout cleaning after cooling. By means of work such as selecting a casting pattern, the molding sand, the coating, metal liquid components, acasting process scheme is optimized, and a novel automobile covering part mold casting is produced finally.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a mold casting method for an auto cover part. Background technique [0002] The R&D and production of automobile panel molds is one of the core technologies for automobile companies to develop new models. At present, high-strength plates used in automobile panels are mainly formed by forging dies. In the production process of traditional forging dies, there are disadvantages such as high raw material prices, high processing costs, complex production procedures, long manufacturing cycles, low assembly and installation accuracy, serious edge wear, poor welding repairability, and short life. When processing molds with large and complex forming surfaces, the material consumption is large and the production is limited [0003] system. The solid casting mold has the characteristics of good near-net formability, low production cost, short processing time, high wear resistance, fa...
