When making injection molds, should the sampling first reset mechanism be considered?

When making injection molds, due to the interference of core-pulling mechanisms such as item ejection devices and row positions determined by the product structure, the mold cannot be closed smoothly, and a reset mechanism needs to be installed. So under what circumstances should the sampling first reset mechanism be considered?

a. When the injection mold is pushed out with a movable insert or a movable die, it is convenient to place the movable insert and the die;

b. Avoid interference between the push rod and the side core;

c. Part of the molded parts are pressed together with the reset lever when the mold is closed to protect the molded parts;

d, to achieve multiple push actions.
