injection mold. What are the rules for designing injection molds?
1. The outer bottom cut (injection mold)
The cavity half protrudes or dents on the outside of the mold, and the mold manufacturing in the Moon Lake area can cause problems when the mold separates the parts, and adjust your parting line to adapt to this.
2. Internal bite edge
Similar to the outer undercut, the raised or recessed mold is half of the inner core.
The problem in a mold, the angle is not always flush, it is almost impossible to force the plastic product to have a perfect angle, the result will appear messy and amateur, not to mention the strength of the parts may be greatly reduced, so all corners To maximize the aesthetics and durability.
The draft is a small angle, usually one or two degrees perpendicular to the dividing line, applied to the face on the mold, which will easily remove the piece from the injection mold, not applied to the draft in the injection molding plant design, will This means that the injection molding machine will not operate the automatic injection system.
The ribs are part of the structural elements of the mold, the plastic mold manufacturing company, for overall stability control. They are thin-walled protrusions that extend vertically from the wall or plane. Adding ribs instead of thicker walls provides greater structural support.
If your mold contains a thread, always arrange it for vertical parting, which will ensure that the vulnerable thread is not damaged. If possible, don't have a thread in your design. Simplifying your design will reduce the chance of a mess.
7. Wall thickness
The wall thickness components are directly proportional to match the components to the required cooling time. By reducing the thickness of the component walls, large mold manufacturing companies can reduce the impact of these two factors, thereby reducing cycle time and thus reducing production costs. If the walls of your parts are too thick or inconsistent, the problem may involve sinking and warping, resulting in scrap and expensive redesigns, ensuring that the wall thickness matches the machine.
