Finally, designers also need to consider production efficiency and cost-effectiveness when drawing mold parts. They need to optimize the design of parts to reduce processing time and cost and increase production efficiency. This may involve using advanced CAD/CAM software to generate accurate part models, as well as selecting appropriate machining methods and equipment to achieve an efficient production process.
All in all, drawing mold parts is a task that requires great attention to detail and precision. Designers must carefully consider every detail, including aspects such as shape, size, function, material selection, assembly and operation, to ensure smooth manufacturing of molds and production of high-quality plastic parts. Through accurate drawings and optimized designs, designers can increase production efficiency and cost-effectiveness, thereby giving businesses a greater competitive advantage. Here are the key requirements for drawing all parts in mold design:
- Dimensional Accuracy: All part drawings must be dimensionally accurate, reflecting the exact specifications and tolerances as specified in the part design.

- Material Specifications: Specify the material to be used for each part, as different parts of the mold may require different materials based on their functions and operating conditions.
- Surface Finish: Indicate the required surface finish for each part, especially for cavity and core surfaces, to achieve the desired level of smoothness and part appearance.
- Draft Angles: Ensure that all parts in the mold design have appropriate draft angles to facilitate easy part ejection and prevent molding defects like undercuts.
- Tolerances: Clearly specify the tolerances for critical dimensions, ensuring that the mold maker can meet the required part accuracy.
- Parting Lines and Gates: Clearly indicate the parting lines and gate locations on the part drawings, as they are essential for determining the mold's layout and overall design.
- Ejection System: Detail the ejection system, including ejector pins, sleeves, and ejection methods, to facilitate part removal from the mold after molding.
- Cooling System: Include the design of the cooling system to efficiently control mold temperature during the molding process and ensure consistent part quality.
- Interference Checks: Perform interference checks between the different mold components to avoid clashes or collisions during the mold assembly.
- Material Selection: Choose appropriate materials for each part based on factors such as wear resistance, thermal conductivity, and corrosion resistance.
- CAD Software: Use advanced computer-aided design (CAD) software to create the part drawings, which allows for accurate modeling, simulation, and analysis of the mold components.
- Communication: Effective communication between the mold designer and mold maker is crucial to clarify any doubts or queries related to the part drawings and to ensure alignment throughout the mold manufacturing process.
By adhering to these requirements and providing comprehensive part drawings, mold designers can ensure a smoother and more efficient mold manufacturing process, leading to the production of high-quality plastic parts in the final product.
The sequence of drawing the part drawing from the general assembly drawing of the mold shall be: first inside then outside, first complex then simple, first molding parts, then structural parts.
1) Graphic requirements: be sure to draw according to the scale, and allow zooming in or out. The view selection is reasonable, the projection is correct, and the layout is appropriate. In order to make the processing patent number easy to understand and easy to assemble, the graphics should be consistent with the general assembly drawing as much as possible, and the graphics should be clear.
2) Dimensioning shall be unified, centralized, orderly and complete. The order of dimensioning is: first mark the size of the main parts and the die inclination, then mark the fitting size, and then mark all the dimensions. On the drawing of non major parts, the matching dimensions shall be marked first, and then all dimensions shall be marked.
3) Surface roughness. Mark the most applied roughness on the upper right corner of the drawing, such as "Other 3.2" Other roughness symbols shall be marked on each surface of the part.
4) Other contents, such as part name, mold drawing number, material trademark, heat treatment and hardness requirements, surface treatment, drawing proportion, machining accuracy of free size, technical description, etc., shall be filled in correctly.
Mold design is a fascinating yet intricate process that demands a high level of technical expertise and meticulous attention to detail. Among the many facets of this process, crafting accurate and comprehensive drawings for all mold components stands out as one of the most crucial tasks. In this article, we’ll delve into the essential requirements for creating these drawings in mold design.

It’s not just about the numbers; labeling these dimensions with appropriate tolerance values is vital to guarantee that the final mold operates as intended. Imagine the frustration of a misaligned part that could derail an entire production run!
Appropriate Views
Next, the drawing should encompass multiple views for each part, such as top, bottom, and side perspectives. Clearly labeling these views is essential to eliminate confusion during the manufacturing phase. Visualize how having a well-structured set of drawings can streamline the entire process, making it easier for everyone involved to understand their roles.
Material Specification
Equally important is specifying the material for each mold component. The choice of material can significantly impact the mold's performance and durability.
