Problems solved by technology

[0002] At present, ordinary casting molds mainly include wooden molds and metal molds. Although wooden molds have the advantage of low material cost, wooden molds need special skilled workers to make them manually. Not only the manufacturing efficiency is low, but also it is difficult to manufacture molds with complex shapes. Metal molds require complex CNC machining and manufacturing, because of high cost, it is not suitable for the production of small batch products

Embodiment Construction

[0023] [Example 1] When the maximum size of the casting mold is smaller than the maximum printing size of the 3D printer, the overall printing of the mold is carried out according to the following steps.

[0024] Step 1. Use 3D mechanical design software to design the casting mold, including the determination of casting slope, casting shrinkage, machining allowance, parting surface and other parameters. After the design is completed, generate an STL format model that can be accepted by the 3D printing slicing software document.

[0025] Step 2: Use 3D printing slicing software to slice the model file of the casting mold, including parameters such as printing temperature, outer layer thickness, and internal filling rate, and generate a general print file in GCODE format acceptable to the 3D printer after processing.

[0026] Step 3, import the general print file into the 3D printer for casting mold printing.

[0027] Step 4, the surface treatment of the casting mold, first rem...

Abstract

The invention discloses a manufacturing method of a casting mold. The manufacturing method comprises the steps of 1, designing a casting mold by using three-dimensional mechanical design software; 2,evaluating the size and the shape of the casting mold, and if necessary, carrying out segmentation design; 3, generating a model file which can be accepted by 3D printing slicing software, 4, carryingout slicing processing on the model file by using the 3D printing slicing software, and generating a printing file; 5, printing the casting mold or partitioning by using a 3D printer; 6, if the moldis segmented, assembling each printed block or base plate; and 7, carrying out surface treatment on the casting mold, removing surface defects, conducting gap and pit filling and smooth polishing so as to complete the manufacturing. By means of the casting mold manufactured according to the method, the manufacturing process can be remarkably simplified, the cost is very low, a mold with the relatively complex appearance can be easily manufactured, and the method can become a brand-new choice in mechanical casting mold manufacturing.

Description

technical field [0001] The invention belongs to the field of mechanical casting mold manufacturing. Background technique [0002] At present, ordinary casting molds mainly include wooden molds and metal molds. Although wooden molds have the advantage of low material cost, wooden molds need special skilled workers to make them manually. Not only the manufacturing efficiency is low, but also it is difficult to manufacture molds with complex shapes. Metal molds require complex CNC machining and manufacturing is not suitable for the production of small batch products due to high cost. Contents of the invention [0003] Aiming at the above problems, the present invention adopts the newly-appearing 3D printing technology to manufacture casting molds. Manufacturing casting molds with the present invention can significantly simplify the manufacturing process, and can easily manufacture casting molds with relatively complex shapes. The manufactured casting molds not only have the c...
