Parametered assembly and design of three-dimensional mould structure and automatic dimension labeling method for two-dimensional figure

Abstract

The related auto size marking method for 3D / 2D mold parameters assembly design comprises: 1. designing mold frame, determining all of the member size, mold nest and core quantity, distance among product, nest and template; 2. designing secondary structure by receiving computer command and calculating to generate slide block, slope pin, cooling loop, and other assembly; 3. executing whole assembly diagram command to generate 2D diagram; 4. alternating request, repeating step 2-3; 5. outputting the formal 2D diagram; 6. outputting the 2D member processing diagram. This invention has more reasonable process, improves design quality, and reduces manual error.

Description

technical field [0001] The invention relates to a mold design method, in particular to a three-dimensional mold structure parameterized assembly design and a two-dimensional drawing automatic dimensioning method. Background technique [0002] See figure 1 As shown, there are multiple 3D mold design software currently available on the market. The prior art uses a computer-aided 3D mold design method, which includes the following steps: [0003] Step 1: Establish the existing mold standard parts, standard formwork database and user interface for accessing standard parts; [0004] Step 2: 3D finished product segmentation; [0005] 2.1 Import other systems to complete the 3D model; [0006] 2.2 Make up the imported 3D model to make it the solid model of the system; [0007] 2.3 Modify the draft angle; check the draft angle of this model, if it does not meet the mold opening requirements, you must modify the model; because the R angle on the appearance of these models has bee...

Problems solved by technology

[0056] The purpose of the present invention is to solve many defects in the existing 3D mold structure design method, and to provide a method for parametric assembly design of three-dimensional mold structure and automatic dimensioning of two-dimensional drawings. The parameters of the mold can be automatically adjusted to make the mold structure design more reasonable and effectively improve the quality of mold design; in the design process, 3D mold structure design and 3D parting can be carried out simultaneously, which can shorten the total working hours of mold design by 50%; The general assembly drawing automatically generates a 2D general assembly drawing, and can automatically mark the size that meets the standard; it can automatically produce a 2D part processing drawing and automatically mark the size of the 3D parts to meet the requirements of production and processing
