In order to ensure the normal operation of the plastic mold, the concave and convex mold inserts can cooperate with each other. When designing, the dimensions and tolerances must be strictly formulated according to the requirements for manufacturing. The verticality of the insert surface and the cutting edge cannot exceed 0.01 mm, and there is no reverse taper, looseness up and down, and the insert seams cannot cross and overlap.
Unless there is a requirement to allow welding of the fixed part of the insert and the cutting edge during design, it is not allowed in principle, because some inserts need to be surface treated later.
It is best to mark the position of the concave and convex molds, the fixing plate, and the mounting plate with the part number. The edge line of the waste cutting edge is determined by the size of the part. There should be no gap between the two working surfaces of the open key and the dark key and they can cooperate with each other.

There are requirements for the parallelism of the key after insertion and the two insertion surfaces. The specific value needs to be determined according to the type and characteristics of the plastic mold.
The coaxiality of the guide post hole and the guide sleeve hole of the upper and lower base plates shall not exceed 0.01 mm. The installation position of the working parts on the base plate shall not have cracks or looseness. The burrs on the lifting platform need to be removed in time. The chamfer size of the upper and lower base plates is set according to the overall size of the mold.
