injection mold, what is a high-precision plastic mold? What should I pay attention to when designing molds?
A high-precision plastic mold is a mold with high design requirements, and its design complexity is also higher than that of ordinary molds. Before confirming the start of construction, it is necessary to ensure that all processes have been determined to avoid problems during the machining process. When designing high-precision plastic molds, you need to pay attention to the following issues:
1. Precision injection mold design engineers should conduct feasibility analysis of plastic product drawings provided by customers, determine the mold structure, and strictly define the process of product design. This is the most important step in the design process, which needs to be completed carefully to save subsequent working hours.
2. Analyze according to the product expansion diagram and prepare various materials needed for precision injection mold design. By preparing materials, efficiency and accuracy can be improved and errors can be reduced, which is conducive to the rapid completion of design work.
3. Determine the opening direction and line position of the high-precision plastic mold. Each plastic product needs to determine the mold opening direction and split line at the beginning of the design to minimize the core slider mechanism and reduce the impact of the split line on the appearance.
4. After determining the direction of mold opening, select the appropriate split line to avoid inversion and improve the appearance and performance of the mold.
5. Adjust the drawing slope of the mold to avoid damage such as white edge, deformation, cracking, etc. on the top of the product. When designing deep cavity structure products, the slope of the outer surface should be greater than the slope of the inner surface to ensure uniform product wall thickness, while ensuring material strength and product opening time.
6. Different plastics have different wall thickness range. If the wall thickness exceeds a certain value, it will lead to long cooling time, shrinkage and other problems. It is necessary to consider changing the product structure. Uneven wall thickness can lead to surface shrinkage, pores and welding wires. Reasonable use of reinforcing bars can increase product stiffness and reduce deformation.
The design and manufacture of high-precision plastic molds is a highly technical project that requires the cooperation of professional mold design and development companies. In this regard, Donglai Mould Company can provide professional consulting and services. The design and manufacture of high-precision molds requires rigorous processes and expertise. Only in this way can we ensure that the quality and performance of the final product meet the requirements of customers.
