Embodiment Construction

[0027] The present invention provides a method for preparing a sand mold by using a reverse mold and a sand mold preparation method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The invention provides a method for preparing sand molds by using reverse moulds, which is suitable for preparing sand molds with complex structures and many ravines.

[0029] Specifically, the method for preparing a sand mold using a reverse mold comprises the following steps:

[0030] a. On the three-dimensional model of the sand mold, add the processing quantity to obtain the three-dimensional model of the sand blank with the processing quantity; wherein, the three-dimensional model of the sand mold is as follows fi...

Abstract

The invention discloses a method for preparing a sand mold by using a reverse mold and a sand mold preparation method. The method for preparing the sand mold by using the reverse mold comprises the following steps: manufacturing a simple reverse mold by using a material which can be easily processed, preparing a sand blank with processing margin by using the reverse mold in a sand turning manner, and finally performing digital milling processing, thereby obtaining the sand mold. The method is particularly applicable to preparation of sand molds which are complex in structure and relatively rich in groove, the cutting workload can be greatly reduced, and the preparation efficiency of the sand mold can be improved.

Description

technical field [0001] The invention relates to the field of sand mold casting, in particular to a method for preparing a sand mold by using a reverse mold and a sand mold preparation method. Background technique [0002] Sand casting refers to the casting method that uses sand molds to produce castings. Cast steel, cast iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, and the sand mold is easy to manufacture, it can be adapted to single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. [0003] There are mainly three kinds of existing sand mold preparation methods, one is to use mold foundry molding (suitable for mass production), the other is to use 3D printing method to accumulate molding (suitable for single piece and small batch production), and the other is to use It is processe...
