Mold Design Drawing Management
A comprehensive framework for efficient organization, version control, and retrieval of critical documents in mold injection design processes.
In the mold design and production process, drawing management is a core环节 ensuring research and development efficiency and reducing communication errors. A unified drawing naming convention serves as the foundation for standardized management. A scientific naming system enables quick file localization, version iteration tracking, and clear identification of drawing types, providing clear guidance for team collaboration, production对接, and later maintenance. This page details the naming conventions and management essentials for mold design drawings, integrating industry practices with modern mold injection design principles.
Effective document control in mold injection design environments requires meticulous attention to structure and consistency. By implementing the guidelines outlined here, organizations can significantly improve their operational efficiency while reducing costly errors in the production cycle.
Core Value of Drawing Naming
Mold design involves multi-dimensional information such as product structure, mold base parameters, and part details, with various drawing types (e.g., assembly drawings, part drawings,塑件 drawings provided by customers) that undergo multiple version iterations. Without unified naming conventions, problems such as file duplication, version confusion, and difficulty in finding files easily arise.
This is particularly critical in mold injection design where precision and accuracy are paramount. In multi-team collaboration or cross-departmental对接, inconsistent naming can lead to production errors, wasted resources, and delayed timelines.
Therefore, standardized naming is key to achieving "one drawing, one code; one code, complete identification." It can significantly improve file retrieval efficiency – industry statistics show that standardized naming can reduce drawing查找时间 by more than 60%.
Additionally, it lays the foundation for the integrated application of ERP systems and PDM (Product Data Management) systems, which are essential components of modern mold injection design workflows.
Efficiency Improvement with Standardized Naming in Mold Injection Design
Composition Structure and Analysis of Naming Conventions
The naming of mold drawings should include "core information fields + format identification," forming a structured code connected by separators. Taking the example "1008-01-01-A-1.dwg," its composition logic from left to right is: Product Number - Mold Number - Drawing Number - Drawing Type Code - Version Number. File format. Each field's meaning is as follows:
Product Number
Usually a 4-6 digit number/letter combination representing the corresponding plastic part product model, uniformly compiled by the enterprise according to product series. For example, "1008" can represent a product code for a home appliance shell. This number must strictly correspond to the enterprise product ledger to ensure uniqueness in mold injection design projects.
Mold Number
2-3 digits used to distinguish different molds for the same product (e.g., single-cavity mold vs. multi-cavity mold, different batches of molds). In the example, "01" represents the first set of molds for the product. If a modified version of the mold is developed later, it can be numbered "02", "03", etc., which is crucial for tracking variations in mold injection design.
Drawing Number
2-3 digits used to identify different drawings of the same mold. For example, "01" can represent the general assembly drawing, "02" the cavity part drawing, "03" the gating system drawing, etc. The numbering rules must be unified within the enterprise (it is recommended to prepare a "Drawing Number Compilation Instructions Table" for reference in mold injection design documentation).
Drawing Type Code
A single letter identifying the drawing type, which must strictly match the drawing content to avoid confusion. This classification is essential for organizing documents in complex mold injection design projects.
| Code | Type |
|---|---|
| A | Assembly |
| L | Layout (Sketch) |
| P | Product (In-house) |
| Z | Product (Customer) |
| M | Mold Base |
| D | Detail (Part) |
Version Number
Identifies the number of iterations of the drawing, which can be represented by numbers (1, 2, 3...) or letters (A, B, C...). In principle, the first release is "1" or "A", and increments sequentially after modifications. For example, "1008-01-01-A-2.dwg" indicates the second version of the assembly drawing. Modifications should be noted within the drawing (e.g., "20250802 corrected cavity fillet dimensions") to maintain clarity in mold injection design revisions.
File Format
Determined according to the design software type, common formats include .dwg (AutoCAD), .prt (Pro/E), .step (general exchange format), etc. Ensuring compatibility is vital as these files need to be accessible to downstream departments (e.g., processing workshops, quality inspection departments) involved in the mold injection design and production process.
Distribution of Drawing Types in Typical Mold Injection Design Projects
Practical Examples and Considerations
Example 1: Part Drawing
This represents the first version (1) of a detail part drawing (D) for the 3rd component (03) in the first mold set (01) of product number 1008, saved in AutoCAD format (.dwg). This type of precise identification is crucial for tracking individual components in complex mold injection design projects.
Example 2: Customer Product Drawing
This represents the third version (3) of a customer-provided product drawing (Z) for the first drawing (01) in the second mold set (02) of product number 2156, saved in AutoCAD format (.dwg). Maintaining clear references to customer-provided documents is essential in mold injection design workflows.
Management Considerations in Mold Injection Design
Uniqueness Principle
Each drawing (including different versions) for the same mold must ensure unique numbering throughout its lifecycle to avoid conflicts with historical files. This is especially critical in mold injection design where precision is paramount.
Relevance Principle
Drawing numbers must correspond to part numbers in the mold BOM (Bill of Materials). For example, "01-03" corresponds to the code for "cavity plate" in the BOM, creating a seamless integration between design and production in mold injection design processes.
Traceability Principle
Version number changes must be recorded in the "Drawing Version Change Table" with notes on the modifier, time, and reason, facilitating problem tracking. This audit trail is essential for quality control in mold injection design.
Adaptability Principle
If enterprise products are complex (e.g., automotive panel molds), fields can be expanded (such as adding "process code"), but the entire company must update the rules simultaneously to maintain consistency across all mold injection design projects.

Conclusion
The standardized naming of mold drawings is a fundamental project for enterprise digital management. Its core lies in transmitting the entire chain of information from "product - mold - drawing type - version" through structured coding. This systematic approach is especially valuable in the complex field of mold injection design where precision and collaboration are essential.
Enterprises must formulate specific rules based on their own product characteristics (such as home appliance molds, automotive molds, precision stamping molds) and ensure unified implementation across design, process, production, and other departments. Training programs should be implemented to ensure all team members understand and adhere to these conventions in their mold injection design work.
Only by achieving "every drawing can be traced, every number has meaning" can enterprises improve collaboration efficiency and reduce management costs in the rapidly iterating manufacturing environment. This level of organization is particularly critical in mold injection design where errors can lead to significant financial losses and production delays.
