How is the easy damage of the injection mold at the molding stage?
Injection mold refers to the process of processing a mold through injection molding, but if the process is not well grasped, the material will be easily damaged; and if the injection mold tool is used for a long time without careful maintenance, it is also prone to damage. The company caused losses, so what are the reasons for the damage?
So, why is the injection molding mold damaged? Everyone knows the injection mold when assembling, there is not much force applied from the outside, but once installed in the injection molding machine, the injection molding will be subjected to various external forces and cause damage to the injection mold. Therefore, the injection mold must have enough The strength to withstand various external forces.
Generally, the molten resin will flow to the gate, and then the cavity will be filled. However, the injection strength must be large enough to make the material flow into the gate. The pressure will generally be maintained for about 1s, but it will still cause damage to the mold. It's a tiny shock.
In addition, the push rod of the injection mold can also push out shaped products under the action of the push plate. If the push rod is not smooth enough, the operator will usually apply more force to complete the human action, which also requires the push rod to have a certain pressure-bearing capacity.
