Product: Earphone Clip
Material: PC
Number of holes: 1X1
Product features: Simple shape, complex structure, minimize clamping line.

1. First, perform slope analysis. From Figure 1, it can be seen that this mold has 4 undercuts.

2. From Figure 2, it can be seen that this set of molds has 3 undercuts, and a total of 7 undercuts.

3. Through thickness analysis, it can be obtained that basic wall thickness of product is 2.3mm.

4. Confirm that two small sliders (slider 1 and slider 2) are made at undercut 1 and undercut 6.

5. Undercut 2 and undercut 5 are inside product, so they can only be made into inner sliders, and mold frame is added with a support plate for secondary ejection.

6. Undercut 4 and undercut 7 are confirmed to be ejected with sliders 5 and 6.

7. Slider 7 has no undercut, and it is made into a slider to meet need to reduce clamping line.

8. Undercut 3 is ejected by an lifter. Since there are sliders all around, clamping force is small, and ejection is borne by this lifter.

Looking at this mold as a whole, conclusion is as follows: This is a very simple product, but structure is not simple. A total of 7 sliders and one lifter are used.
