How is the computer mold designed?
CAD is the abbreviation for computer aided design.In the literal sense, it USES computers to process the following design work.
1.The shape design of the part.
2.Using the shape of computer parts, it is transformed into mold design.
3.To print detailed engineering drawings with caption notes.
The computer needs to know the following information before operation.
1.The thermal properties of various metals and plastics.
2.The standard parts (such as DME, HASCO and other standard parts) are sold in the market.
Next, the designers use the keyboard input some pieces of information, such as pieces of plastic, injection mold material, the thickness of the cavity and a transverse area, such as CAD system and according to some hypothesis (for example, all the heat from the cooling system of melting away, cavity surface temperature is uniform, etc.), compute a series of relatively different cavity temperature of cooling time.Designers decided to adopt a cooling time, the computer and then to the coolant flow analysis, then computers require designers to provide cooling pipe diameter, the best position it arranged pipe.
After deciding the cooling system design, the next step is to select the appropriate thickness of the template.The computer system database has the size and price of each standard plate, from the known number of cavity and placement and the design of the runner system, the computer can select the appropriate die plate.
After the mold dimension is determined, the designer can further determine the size, number and position of other parts in the mold cavity.
Finally, the computer system displays the design of the full set of dies, prints the chart, lists the manufacturing cost of the mould, and stores the complete set of data.
Computer aided drawing system after launch, the old drawing equipment already was washed out gradually, the computer aided mapping can not only provide fast accurate drawing method, at the same time, more can easily on the engineering drawing with any form of interpretation, replace the drawing board is a computer screen, replace the other drawing instrument is tablet, input keyboard and computer
The program.
Computer aided drawing system for handling repetitive tasks, the most efficient in order to design the mould cavity more as an example, design staff only need to input a set of mold design, computer programs can be copied, but also the other standard parts of the graphics storage for later use, designers do not need to repeat input at a time.
Advantages of CAD: using CAD can bring a lot of advantages to mold designers, not only saving design time, but also improving accuracy.
CAD can save time depending on the mold size and complexity, design a simple set of mould, the CAD could not much faster than manual method, but with the increase of complexity of the mould, the CAD of comparative advantage is obvious.For example, CAD design a set of half - ton computer shell mold can be completed in 16 weeks, if the traditional method needs 24 weeks.
