By adopting the technical scheme, the gap can be plugged in the injection molding process by arranging the template, the spring, the movable insert, the aluminum piece and the clamping groove, so that the gap position forms a smooth angle, and the situation of burrs is avoided.
The utility model is further provided with: the surface of the movable insert is in sliding connection with the inside of the die core, and the bottom end of the movable insert is in clamping connection with the aluminum piece.
By adopting the technical scheme, through the surface of movable inserts and the inside sliding connection of mould benevolence, the bottom and the aluminum part joint of movable inserts play with the aluminum part contact, have shutoff clearance avoided moulding plastics can appear the condition of deckle edge.
The utility model is further provided with: the bottom of the spring is bolted with the template through a spring fixing piece, and the bottom of the spring is bolted with the movable insert through a spring fixing piece.
By adopting the technical scheme, the movable insert is pushed to be clamped with the aluminum piece downwards through the arrangement of the springs.
The utility model is further provided with: the inside of template has seted up the mounting groove, the spring is located the inside of mounting groove.
By adopting the technical scheme, the spring is installed through the setting of mounting groove, also is used for accomodating the spring simultaneously.
The utility model is further provided with: an injection molding hole is formed in one side of the die core.
By adopting the technical scheme, the plastic products are injected into the mold core through the arrangement of the injection holes.
In summary, the utility model has the following beneficial effects:
according to the utility model, the movable insert is manufactured in the die core, the die plate with the spring is arranged at the top of the movable insert, the movable insert can be ejected out by the spring, so that the bottom end of the movable insert is tightly attached to the aluminum piece, and then injection molding is carried out, so that the burr phenomenon caused by gaps in the injection molding process can be avoided, and the yield and quality of products are improved.
