Description

Technical Field

[0001] This invention relates to the field of computer-aided design technology, specifically to a parametric mold drawing method, system, device, and storage medium. Background Technology

[0002] In the mold manufacturing industry, mold design is a crucial preliminary step. Currently, design work heavily relies on the manual experience and operation of engineers. Because different customers and even different product lines often employ their own independent design standards, engineers must manually review, verify, and convert a large number of standard parameters when designing each new mold—a tedious and error-prone process. Even when using general-purpose software with parametric capabilities, engineers must manually create and associate all dimensional parameters and geometric shapes for each mold, essentially repeating the basic modeling work "from zero to one." This method has a high professional threshold, a large initial setup workload, low design efficiency, and makes it difficult to quickly reuse existing design experience for new projects.

[0003] Therefore, in mold design, especially in the core stage of mold base design—which has a relatively high degree of standardization and complex parameter relationships—there is an urgent need for a dedicated solution that can solidify design specifications and lower the operational threshold. This solution needs to guide users to quickly complete the input of key parameters and automatically generate accurate structural diagrams, thereby freeing engineers from repetitive, error-prone low-level drafting work and allowing them to focus on creative and optimization tasks. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The present invention aims to solve the problem of low efficiency in the design of molds (mold frames) in the prior art due to reliance on manual operation of general software or self-built parametric models.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Firstly, this invention provides a parametric mold drawing method. Its core lies in guiding the user to input parameters through a series of graphical configuration interfaces, each with labeled schematic diagrams, and automatically driving the drawing engine to generate the drawing based on these parameters. This method transforms the originally discrete and tedious manual drawing steps into a coherent, intuitive, and automated parameter-driven process.

[0009] Secondly, the present invention provides a system for implementing the above-described method.

[0010] In the third and fourth aspects, the present invention also provides corresponding electronic devices and storage media to ensure the complete protection of the technical solution.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Lower the professional threshold: Guide users to input through an interface with labeled diagrams.

[0014] 2. Improve initial design efficiency: Automatic generation via parametric methods avoids manual drawing from scratch.

[0015] 3. Ensure basic accuracy: Parameter-driven approach ensures consistent dimensions.

[0016] 4. Easy to modify: The graph can be updated simply by changing the parameters. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1:

[0024] Reference Figure 1 This embodiment provides a parametric mold drawing method, including the following steps:

[0025] S101: The system starts up, and the user can select or specify a machine model on the main interface. The system automatically retrieves the corresponding standard mold parameters from the preset parameter library based on the model.

[0026] S102: The system displays as follows Figure 3The "Part Parameters" interface is shown below. The left side of the interface displays a schematic diagram of the part, and the right side is the parameter input area. Users can refer to the schematic diagram to input these parameters.

[0027] S103: The user switches to the "Mold Base Parameters" settings. For example... Figure 4 As shown, the system displays the "Front Side of Mold Base" interface. The left side of the interface displays a detailed front view of the mold base, with key dimensions of each component marked with identifiers. The right side displays a list of corresponding parameters. The system automatically fills in the initial values ​​obtained from S101. Users refer to the diagram to understand the physical meaning of each parameter and input or confirm it. Subsequently, users can switch to the "Side Side of Mold Base" interface for similar operations, which also provides a marked side view.

[0028] One of the key innovations of this invention is that each parameter configuration interface is equipped with a schematic diagram with parameter identifiers that strictly correspond to its function. This design ensures the intuitiveness and accuracy of the input process, solidifying professional mold knowledge into visual interactive logic.

[0029] S104: After confirming all interface parameters, the user clicks the "Generate Drawing" command.

[0030] S105: The system enters the automatic drawing stage. (Refer to...) Figure 5 The core of this stage is:

[0031] S1051: The parameter processing module integrates all parameters input from the interface.

[0032] S1052: The drawing engine driver module parses the parameter set based on the internally predefined parameter-geometric mapping rule library. For example, the rule library defines: the part length X plus dimension A1 is the length of the mold core, the part width Y plus dimension A1 is the width of the mold core, the length and width of the mold core plus A2 are the length and width of the template, and A3 is the width of the mold foot.

[0033] S1053: For 2D engineering drawings, the module is invoked through the application programming interface (API) provided by the drawing engine. For example, when the drawing engine is AutoCAD, it can be driven through its provided AutoLISP, ObjectARX, or .NET API; when the drawing engine is ZWCAD, it can be driven through its compatible LISP or ZRX API. The system converts mold parameters into corresponding API call instructions according to predefined parameter-geometric mapping rules (e.g., calling the command function in AutoLISP to execute the "-LINE" command and passing in the calculated coordinate points), thereby automatically generating accurate two-dimensional contour graphics.

[0034] S1054: For 3D assembly models, the module calls the APIs of software such as SolidWorks and UG to automatically create 3D features such as extrusion and mirroring based on geometric properties, and completes the assembly.

[0035] S1055: Finally, generate mold structure drawings or models that conform to engineering standards.

[0036] S106: Users can save all parameters of this assignment as a named template (such as "XXT-XX template diagram") for direct use in the future, realizing the accumulation and reuse of design knowledge.

[0037] Example 2:

[0038] Reference Figure 2 This embodiment provides a parametric mold drawing system 200 for implementing the above method, including:

[0039] User interaction module 210 is used to provide Figure 3 , Figure 4 The core feature of graphical interfaces is that each interface integrates and displays a schematic diagram with identifiers.

[0040] The parameter processing module 220 is used to integrate and verify parameters and manage the parameter-geometry mapping rule base.

[0041] The drawing engine driver module 230 is used to control the external drawing engine 240 to perform graphics generation based on parameter instructions.

[0042] The parameter initialization module 250 (optional) is used to automatically fill in the initial parameters according to the machine model selected by the user.

[0043] Storage module 260 is used to store parameter library, rule library, templates and generated drawings.

When the program is read and executed, it enables a computer device to perform all or part of the steps of the method described in Embodiment 1.
