  Undoubtedly, mold maintenance actually originated from the design department, when the core features of the mold mechanism were worked out. Moreover, they in turn are reflected in the way of operation, wear and stress, and the complete ability of the tool to withstand the responsibilities it assumes.

 

  The mold designer can put in some considerations, and can also make some predictions about the possible working conditions that a particular design will eventually encounter. By providing simple modifications, many small obstacles in construction and operation can be foreseen and prevented. It is relatively easy to get a job in the first stage.

 

  Mold designers with extensive and up-to-date workshop experience will be able to visualize the entire construction method of manufacturing and operation before transferring any of their design details to paper. He will establish a purely psychological temporary design outline, depicting all the different parts, with their respective functions, mutual movements, and how each part will be constructed and produced.

 

  If the designer has useful machining knowledge applied to the manufacture of plastic molds, he will be more capable of evaluating the degree and influence of the stress, wear and pressure that may be applied to each part of the mold during use, and sometimes in the various manufacturing processes. This process is equally important.

 

  It often happens that some precision mold parts are over-tensioned or weakened by the machining operations performed on them before they are assembled in place and exposed to working conditions.

 

  Therefore, among other important matters, he will have a good understanding of the power required to remove the sliding core, or the power required to operate the ejector mechanism, the effect of pressure, heat or moisture on the various metals used in the sliding core. Die, theoretically difficult to calculate.

 

  With this knowledge in the initial stage of mold design, designers will be able to better foresee the many operational difficulties that may occur in the future, so that they can adapt to any design project to ensure the maximum service life and efficiency.

 

  Much has been written about the subject of satisfactorily linking the characteristics of mold design to the optimal molding and operating requirements required in various molding processes. A large number of illustrations show the selected mold structures and the reasons for their preference over other types, while providing practical advantages from their applications.

 

  From these illustrations, we can see how important the designer's role is in the process of creating the mold structure. These mold structures can best ensure the least maintenance workload and the greatest applicability to the required finished products.

 

  Certain well-defined construction methods will be noted, and these methods have been repeatedly proven in actual work practices to provide the most satisfactory operation and products.

 

  The examples of these designs and methods will be limited to some special units or functions of the plastic mold in each aspect, such as cores, jets, gates, pins, etc., in the entire range of traditional mold components.
