Battery Door Cover Plastic injection Mould

 

In fact, spring angle lifter is designed using the principle of spring elastic deformation, so the use of steel is the first key point and the second is the shape of the angle lifter. As long as the two keys are mastered, the design of spring angle lifter is much more simple. The steel used in spring angle lifters must have excellent properties, the most commonly used is special spring steel.

 

Figure a) is the state that Spring angle lifter has not been assembled into the mold after the angle lifter processing is completed, figure b) is the state that Spring angle lifter has been assembled into the mold after the angle lifter processing is completed, and figure c) is the trend comparison of the elastic deformation before and after the angle lifter assembly. It can be seen that the angle lifter has an angle change before and after assembly.

   

                                                                                                                                        

 

When the angle lifter is ejected together with the product, the angle lifter is restored to the original state under the action of elastic deformation and the change of angle, thus taking the undercuts of Battery Cover Plastic Product. This angle is not constant, which is determined by the mold designer according to the depth of undercuts design. The minimum deformation space and deformation distance at this angle must be greater than the depth of undercuts.

You also need to design the spring angle lifter with the following main issues:

A) Ejector Pins must be arranged around the angle lifters, because the spring angle lifter can not withstand a greater force.

B) The spring angle lifter is inmovable on the ejector pin plates, it`s unlike the usual angle lifters.

C) The thickness W could not even bigger, normally it`s designed 2-3mm is fine which is determined by the size of angle lifter.

Spring angle lifter is a bit simple processing, easy to use, usually used in the case of very small space, the disadvantage is only suitable for the case of shallow product undercuts, when the undercut is larger than 3mm, it should be cautious use. Because when the undercut is deep, the angle that needs to change is also more larger, the elasticity of angle lifter is easy to fatigue, and the working action is easy to fail.
