Plastic Injection Mold Design about 3D parting and 2D alignment

After the product study is finished, the plastic injection mold design begins. Using the appropriate software, the mold’s structure is estimated based on the product’s many structural properties.

Mold design primarily refers to 3D parting and 2D alignment in today’s modern processing conditions, and is the primary responsibility of mold designers.

3D-Parting Plastic Injection Mold Design

Parting, sometimes referred to as mold removal, is the process of dividing the mold (blank) into the fixed and mobile molds that make up the mold cavity using plastic injection mold design software. Particularly, the product is divided into fixed/movable mold insert, lifter, slider, insert, etc. using 3D software (such as Pro/E, UG, etc.) after the 3D model of the product has been shrunk.

The main task in the entire Plastic Injection Mold Design process is 3D splitting. The moving/fixed mold core and other relevant components of the products generated in the mold cannot be designed before parting, and the data file cannot be made available for further part processing until parting.

Not just software processes are included in 3D parting. You would be mistaken to believe that understanding 3D parting alone makes you an expert in plastic injection mold design. Back then, the items were fairly basic, computers weren’t widely used, and molds could be created using simple machine tools and human calculations. But as product needs are continuously improved, product structures are growing more and more complicated, making it impossible to create a mold using human calculations and standard machine equipment.

For instance, different complicated surface components of the product can no longer be manufactured manually using calculations and machine tool shaking: instead, numerical control machining is required. But when employing CNC machining. A toolpath program must be compiled, and to do so, a part model must first be acquired. This part model represents the 3D component of the mold that was created automatically by computer splitting. Therefore, it is simply impossible to design and process molds without 3D splitting for today’s mold processing.

Even while the 3D splitting is carried out automatically with the aid of software, the software is not all-powerful, it is unable to determine which structure to apply where. Software’s sole purpose is to take the place of the human brain in mathematical computations and program simplification. Designers must be knowledgeable in the design of mold structures before using software to operate and communicate design concepts. Both the processing ability of the divided components and the logic of the organization are up for debate.

Mold CAD/CAE/CAM technology is now widely used since it has shrunk so much. It doesn’t need a lot of manual calculations to design Plastic Injection Mold pieces. It could be created using software (like Pro/E UG, etc).

2D-Alignment Plastic Injection Mold Design

Although it also includes drawn parts, wire cutting drawings, electrical discharge machining drawings, etc., the 2D assembly drawing mostly refers to the drawn mold assembly drawing. Drawings are crucial for processing molds. Drawings are still necessary for the majority of processing organizations, even under digital processing settings.

In most cases, the designer must create a 2D assembly drawing and perform a 2D ranking for the usage of the processing masters in each step of the processing workshop after finishing the 3D mold removal. 2D assembly drawings must be drawn, comprehensively, and correctly.

Comparable to 3D separating is 2D alignment. It is polished. Drawing does not require the use of AutoCAD, and 2D alignment can only be completed by someone who is knowledgeable about the design of mold structures and is a specialist at utilizing plastic injection mold design software. It requires constant practice to become proficient in the many nuances and sketching techniques that are essential to representing the structure of the mold when it comes to specific locations.
