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

Abstract

The invention relates to a method for parameterized assembly design of three-dimensional mold structure and automatic dimensioning of two-dimensional drawings. ; Determine the distance between the finished product, the mold core and the template; Step 2: Design the mold sub-structure, respectively execute the instructions of the slider structure, inclined pin structure, cooling circuit, small entry structure, and ejection structure of the main components of the mold, through the computer Calculate, generate slider, inclined pin, cooling circuit, small entry sub, thimble components; Step 3: Execute the command of the assembly drawing to generate a two-dimensional assembly drawing; Step 4: Change the design requirements, and repeat the instructions of Step 2 and Step 3; Step 5: Output the official 2D final assembly drawing; Step 6: Output the 2D part processing drawing with automatic dimensioning. The present invention makes the mold structure design more convenient and the flow more reasonable, improves the mold design quality, shortens the total mold design man-hour, and reduces human errors.

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
