Rapid flow groove mold design is a complex and meticulous process, in which cavity arrangement is a crucial link. When determining the number of cavities and their arrangement, it is necessary to comprehensively consider the geometric structure characteristics of the plastic parts, dimensional accuracy requirements, batch size, mold manufacturing difficulty and mold cost. For small parts, a single cavity mold is often used, while for large parts, multiple cavities are required for efficient production. In multi-cavity molds, the arrangement of cavities can be arranged in different layouts according to the shape, size and production requirements of the plastic parts, such as in-line, staggered, rotary, etc. Flow groove mold
In addition to the cavity arrangement, the determination of the parting surface of the rapids groove mold is also crucial. The position of the parting surface should be conducive to mold processing, venting, demoulding and molding operations, and ensure the surface quality of plastic parts. In the design of the parting surface, it is necessary to consider how to ensure the strength and stiffness of the mold, and how to easily install and disassemble the mold parts.
In addition, determining the gating system and exhaust system is also an important part of the rapids groove mold design. The gating system should ensure that the plastic melt flows evenly into the cavity and avoids eddy currents and dead spaces. The exhaust system should be able to effectively remove the gas from the cavity and avoid defects such as porosity and charring.
When choosing an ejection method, the shape, size and production requirements of the plastic part need to be considered. For the selection of the concave treatment method, the geometry and production requirements of the plastic part need to be considered. The choice of core-pulling method needs to be determined according to the shape and size of the plastic part.
Finally, deciding the cooling and heating method, the shape and position of the heating cooling groove, and the installation position of the heating element are also a non-negligible part of the rapid flow groove mold design. Proper cooling and heating design can effectively control the mold temperature, improve production efficiency and ensure the quality of plastic parts.
