2. Mold and Sliders Design 

a.     As the size is big, so we can only make 1*1 cavity;

b.    We can only make 3 plates mold or hot runner;

c.     Based on 3 plates mold, we designed 6 gates, one side with 2 gates, other sides with 4 pin 

     gates transfer to subgate;

d.    There are two undercuts on the top side, we design two sliders;For four sides, we have to

     make 5 sliders, all of the 5 sliders on core (punching mold)

f.      We have to use 4 big eject pin to drive the sliders.

3. About Sliders Design on Core Mold

    The fiver sliders on the foures sides of the plastic part are all core mold sliders. Due to the high

    height of the plastic part, the corresponding slider height is also high. The sliders are all driven 

    by inclined guide columns, and the bottom of the sliders is guided by T-shaped grooves, as 

    shown in picture blow. The wear plates of the core die sliders are all designed on the slope of 

    the sliders, and the whole wedge is opened on the A plate. The mold locking force can 

    effectively resist the lateral separation force of the 5 sliders. Because the sliders is very high, the

    inclined guide column must be designed at the lower part of the tail of the slider to make the 

    slider move smoothly. The three large sliders are very wide, and the three inclined guide 

    columns are designed respectively. The installation of the inclined guide columns adopts a  

    fixed block to extend the wedge, and after pressing the slider, it acts as backhoe. This installtion 

    scheme has a simple structure and is convenient for mold processing. The positioning of the 

    slider adopts out-of-mold spring positioning. If the spring is designed at the front end of the 

    slider, the failure of the spring is not not easy to detect, and it is easy to cause and injection 

    accident.

4. About the deisgn for the Eject Pin, water system 

    The ejection pin of plastic parts adopts 4 inclined tops and ejector pins. The cooling system of 

    the mold adopts the front mold to directly transport water, and the core mold is cooled by a pool.

    The large slider also adopts straight-throught water transportation, which effectively improves 

    the cooling efficiency.In terms of the mold structure, for large molds, if a three plate mold is 

    designed, it is not enough to reply on nylon buckles when opening the mold. A spring must be 

    added between the runner push plate and A plate to assist in opening the mold to ensure that 

    the runner condensate is in the first place. It was pulled off during the second parting.
