What are the technical requirements of the mold general assembly drawing?

A mold’s general assembly drawing is a vital document that provides an overview of how all mold components fit together to create a complete mold assembly. For moldmakers, it is a blueprint that guides their work during the process of making and assembling molds.

This general assembly drawing shows the various components of the mold in detail, including the mold base, mold base, mold core, mold cavity, etc. By carefully studying this drawing, the manufacturer can clearly understand the shape, size, and location of each component, as well as their relative relationship to each other. This helps ensure that no errors or omissions occur during the manufacturing and assembly process.

In addition, the general assembly drawing also marks the fit and connection between various components. For example, it might show how bolts, screws, or other fasteners are used to hold various components together. These details are very important to manufacturers because they determine the stability and reliability of the mold.

In addition to providing detailed component information, general assembly drawings may also contain notes and instructions to help the manufacturer better understand and implement the requirements on the drawing. These notes may include guidance on material selection, surface preparation, processing requirements, etc.

In summary, a mold’s general assembly drawing is an essential document that provides the manufacturer with the details and guidance needed to build and assemble the mold. By carefully studying and following this drawing, manufacturers can ensure the quality and performance of the mold as expected and minimize errors and issues during the manufacturing process. Here are the technical requirements of a mold general assembly drawing:

  1. Accurate Representation: The general assembly drawing should accurately represent the final mold assembly, including the placement and orientation of all mold components.
  2. Scale: The drawing should be drawn to scale, allowing the mold maker to interpret the dimensions and proportions accurately.
  3. Part Identification: Each individual mold component should be clearly labeled with a part number or description for easy identification during fabrication and assembly.
  4. Exploded View: An exploded view can be included to show how the various mold components fit together, indicating the order of assembly.
  5. Bill of Materials (BOM): The general assembly drawing should include a comprehensive bill of materials, listing all the mold components, materials, and quantities required for assembly.
  6. Assembly Sequence: Provide clear instructions on the sequence of assembly, highlighting any critical steps or components that need to be installed in a specific order.
  7. Fit and Tolerance: Specify the fit and tolerance requirements for mating parts to ensure proper alignment and functionality.
  8. Fastening and Connection Details: Include details of how the mold components are fastened and connected, such as screws, bolts, or other fastening methods.
  9. Ejection System: Show the ejection system in the assembly drawing, indicating the location and type of ejector pins, ejector plates, and other ejection components.
  10. Cooling System: Depict the cooling system layout, highlighting the placement and configuration of cooling channels for effective mold temperature control.
  11. Mold Base: Clearly indicate the mold base and its dimensions, as it provides the foundation for the mold assembly.
  12. Annotations and Notes: Include relevant annotations and notes to provide additional information or instructions to the mold maker.
  13. Revision Control: Ensure proper revision control to keep track of any changes or updates to the general assembly drawing.
  14. Compliance with Standards: The general assembly drawing should comply with relevant industry standards, such as ISO, DIN, or ANSI.
  15. CAD Software: Utilize advanced computer-aided design (CAD) software to create the assembly drawing, enabling easy modification and accurate representation of the mold assembly.

By meeting these technical requirements, the mold general assembly drawing becomes an indispensable reference for the mold maker, contributing to the efficient and accurate fabrication of the mold assembly.


Technical requirements for general assembly drawing of mould:


1) Performance requirements for some die systems. For example, assembly requirements for ejection system and sliding block core pulling structure.
2) Requirements for die assembly process. For example, after the mold is assembled, the fitting clearance of the fitting surface of the parting surface shall not be greater than the parallelism requirements of the upper and lower parts of the mold, and the size determined by the assembly and the requirements for this size shall be indicated.
3) Mold use, assembly and disassembly methods.
4) Anti oxidation treatment, mold number, lettering, marking, oil seal, storage and other requirements.
5) Requirements for mold testing and inspection.

The mold general assembly drawing is a critical document in the mold manufacturing process. It provides detailed instructions for assembling the different components of the mold and helps ensure that the final product meets the required specifications. In this article, we will discuss the technical requirements of the mold general assembly drawing.

Firstly, the mold general assembly drawing should provide a detailed view of the mold assembly, including all the different components and their locations. This view should be easy to understand and should clearly show the orientation and position of each component.

Secondly, the drawing should specify the materials used in each component and their specific characteristics. This information is important to ensure that the mold is made using the correct materials and that the final product meets the required quality standards.

Thirdly, the drawing should include dimensions and tolerances for each component. These dimensions and tolerances help ensure that each component fits together correctly and that the mold functions as intended.

Fourthly, the drawing should provide detailed assembly instructions, including the order in which the components should be assembled, the tools and equipment required for assembly, and any other relevant information.

Finally, the drawing should include a bill of materials, which lists all the different components required for the mold assembly. This information is critical for ordering and tracking the different components required for the mold assembly.

In conclusion, the mold general assembly drawing is an essential document in the mold manufacturing process. It provides critical information on the different components required for the mold assembly, their materials and characteristics, and the assembly instructions. By meeting the technical requirements of the mold general assembly drawing, manufacturers can ensure that the mold meets the required quality standards and produces high-quality parts.
