Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] use as figure 1 The manufacturing method of a steel casting forming process casting mold shown in the figure uses furan resin sand molding to produce product model: ZB2.5-75-001-MP, name: rear bearing body, material: 35CrMo steel casting product 15 pieces, it includes the following steps:

[0034] Step 1. Three-dimensional process modeling: Designers use SolidWorks three-dimensional modeling software to carry out three-dimensional process modeling on the casting process of steel castings. The basic process elements of the three-dimensional process model include shrinkage rate, self-hardening resin sand core Negative number, lower core slope, machining allowance, pouring system, cold iron, core bone, air outlet and concession materials, when the casting mold of steel castings needs to be formed by sand mold and multiple sand cores, it is necessary to ...

Abstract

The invention discloses a manufacturing method of a casting mold for a steel casting molding process. By applying SolidWorks three-dimensional modeling software and UG (Unigraphics NX) digital modeling software and employing the processing technology of a digital pattern-less casting precision molding machine, corresponding positions of process elements: a gating and riser system, a chilling block, a core iron and a deformability material and the like, included in the steel casting molding process are processed and reserved; then, a steel brick tube, a thermal insulation bush required by a riser, the chilling block, the corn iron and the deformability material are put into a processed sand mold, and are assembled and fixed, and casting is performed to obtain a product. Compared with a traditional production mode of manufacturing a pattern according to a traditional casting molding process and manufacturing the sand mold by utilizing the pattern to form the casting mold, the productionmode of the manufacturing method disclosed by the invention does not need to manufacture a solid pattern and does not need to consider the factors: the drafting angle and the like, so that the dimensional precision of the casting is increased; the billet weight of the casting can be reduced by 3 % to 5 %; and meanwhile, the problem that a traditional pattern for new product development and new process verification is long in manufacturing period and high in cost is solved.

Description

technical field [0001] The invention relates to the technical field of casting technology, in particular to a manufacturing method of a steel casting molding technology casting mold manufactured by digital moldless molding technology. Background technique [0002] The traditional casting production mode is to make a pattern according to the casting molding process, and use the pattern to make a sand mold to form a casting mold. The pattern production cycle is long and the cost is high, which seriously restricts the output progress of casting products. New product trial production and new process verification are difficult to advance quickly, which affects market development. [0003] Digital moldless molding technology has been applied in the field of casting molding process casting mold manufacturing. It is characterized by changing the traditional casting production mode and saving the pattern production in the early stage of casting forming process, which shortens the pr...
