Description
Technical Field
The utility model relates to a pre-buried copper nut positioning mechanism.
Background
The pre-embedded injection molding is a process of placing a copper nut on a positioning insert and then carrying out die assembly injection molding, and the copper nut is fully wrapped by plastics after injection molding is finished so as to achieve the matching of the copper nut and a product. When the mold is moved for closing the mold, the copper nut can slide on the insert pin due to inertia, and in addition, due to the clearance fit of the copper nut and the insert pin, the copper nut can move up and down on the insert pin due to overlarge injection pressure in the injection molding process. The copper nut moves relative to the insert pin, so that a gap is formed between the copper nut and the sealing glue surface, plastic liquid can enter the gap during injection molding and flows into the inside or the surface of the copper nut, a central hole of the copper nut is plugged by plastic after injection molding is finished, a bolt cannot be normally inserted, and an injection molding product is scrapped.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pre-buried copper nut positioning mechanism, its is rational in infrastructure, has effectively improved the pre-buried stability of copper nut, prevents that the copper nut from taking place the displacement at the in-process of moulding plastics to be favorable to promoting product quality.
In order to achieve the purpose, the technical scheme of the utility model is to design a pre-buried copper nut positioning mechanism, which comprises an upper die and a lower die, wherein the upper die and the lower die are matched to form a cavity in a die closing state; still include iron and insert and magnet, the bottom of going up the mould is equipped with first mounting hole, the setting that iron was inserted and can be got and put is equipped with the connection projection in first mounting hole, and the bottom that this iron was inserted is equipped with the connection projection, should connect the projection and be located the die cavity, and should connect and be equipped with on the projection and be used for the screw hole matched with external screw thread with the copper nut, the top of going up the mould is equipped with the second mounting hole, and this second mounting hole is located the top of first mounting hole, the fixed setting of magnet is in the second mounting hole, and magnet is used for adsorbing fixed iron and inserts.
Preferably, the axial length of the connecting convex column is equal to that of the threaded hole of the copper nut.
Preferably, the top end of the first mounting hole is communicated with the bottom end of the second mounting hole.
Preferably, the aperture of the second mounting hole is larger than that of the first mounting hole, and a step surface is formed between the second mounting hole and the first mounting hole.
Preferably, a sealing cover plate is arranged above the second mounting hole and detachably fixed to the top of the upper template through screws.
The utility model has the advantages and the beneficial effects that: the utility model provides a pre-buried copper nut positioning mechanism, its is rational in infrastructure, has effectively improved the pre-buried stability of copper nut, prevents that the copper nut from taking place the displacement at the in-process of moulding plastics to be favorable to promoting product quality.
