The invention aims to provide an ultrathin soft magnetic iron oxide magnetic core forming die which is put into use and solves the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: an ultrathin soft magnet oxidation magnetic core forming die comprises a whole die formed by splicing two half dies, wherein a pair of symmetrically arranged grooves are correspondingly formed in the binding surfaces of the two half dies, a metal rod is inserted into the inner side of each groove, supporting rods are rotatably arranged on the inner walls of the grooves, the other ends of the supporting rods are rotatably connected with the metal rods, the two half dies have two states,

firstly, the metal rod moves towards the upper end of the whole mold, and the support rod deflects to prop open the mold opening state of the half mold;

secondly, the metal rod moves towards the lower end of the whole mold, and the support rod deflects to pull the closed mold state of the half mold folding;

and a positioning structure is arranged between the bottom of the whole die and the metal rod.

Preferably, the positioning structure is composed of a support plate which is fixedly arranged at the lower end of the metal rod and is parallel to the lower end of the whole die, a pressing bolt which is in threaded connection with the middle of the support plate, and a first U-shaped reinforcing plate which is rotatably arranged at the lower end of the pressing bolt, and when the two half dies are closed, the first U-shaped reinforcing plate clamps two sides of the lower end of the whole die.

Preferably, the supporting rod is U-shaped, and the middle cross rod part of the supporting rod is rotatably connected with the side surface of the supporting rod.

Preferably, a second U-shaped reinforcing plate is fixedly mounted at the upper end of the metal rod, and when the two half molds are closed, the second U-shaped reinforcing plate clamps both sides of the upper end of the whole mold.

The invention has the technical effects and advantages that: this ultra-thin type soft magnet oxidation magnetic core forming die through promoting the motion of metal pole in the recess to thereby it realizes two half module concatenations or separation state to drive the branch relative deflection of both sides, the operation of the realization die sinking of more convenient quick, labour saving and time saving avoids because the condition of die sinking difficulty is caused to the molecule packing force between inner chamber wall and the material, and the practicality is strong, also avoids dragging two half modules at the external force and causes its problem of damaging.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides an ultrathin soft magnetic iron oxide magnetic core forming die as shown in figure 1-2, which comprises a whole die 2 formed by splicing two half dies 1, wherein a pair of symmetrically arranged grooves 3 are correspondingly arranged on the binding surfaces of the two half dies 1, a metal rod 6 is inserted into the inner side of each groove 3, supporting rods 5 are rotatably arranged on the inner walls of the grooves 3, the other ends of the supporting rods 5 are rotatably connected with the metal rods 6, the two half dies 1 have two states,

firstly, a metal rod 6 moves towards the upper end of the whole die 2, and a support rod 5 deflects to expand the die opening state of the half die 1;

secondly, the metal rod 6 moves towards the lower end of the whole die 2, and the support rod 5 deflects to pull the die half 1 to be closed;

and a positioning structure 4 is arranged between the bottom of the whole die 2 and the metal rod 6.

Before the whole die 2 is filled, the metal rod 6 is pulled to move from top to bottom in the groove 3, so that one end of the supporting rod 5 is driven to descend, meanwhile, the other end of the supporting rod 5 pulls the two half dies 1 to be close to the metal rod 6, so that the two half dies 1 are pulled to be folded and spliced to form the whole die 2, the position of the metal rod 6 is fixed through the positioning structure 4, the metal rod 6 is prevented from relatively moving, and the connecting strength of the two half dies 1 is ensured;

the configured mixed material is poured into the inner cavity of the whole die 2 for compression molding, the locking of the fixing mechanism to the relative position between the support rod 5 and the whole die 2 is firstly released, the metal rod 6 is pushed to move from bottom to top in the groove 3, so that one end of the support rod 5 is pushed to move from bottom to top, the other end of the support rod 5 pushes the two half dies 1 to be away from each other, the rapid die parting is realized, the condition that the die opening is difficult due to the molecular pressing force between the inner cavity wall and the material is avoided, and the practicability is strong.

The positioning structure 4 is composed of a supporting plate 41 which is fixedly arranged at the lower end of the metal rod 6 and is parallel to the lower end of the whole die 2, a pressing bolt 42 which is in threaded connection with the middle of the supporting plate 41, and a first U-shaped reinforcing plate 43 which is rotatably arranged at the lower end of the pressing bolt 42, when the two half dies 1 are closed, the first U-shaped reinforcing plate 43 clamps two sides of the lower end of the whole die 2, the upper end of the metal rod 6 is fixedly provided with a second U-shaped reinforcing plate 7, and when the two half dies 1 are closed, the second U-shaped reinforcing plate 7 clamps two sides of the upper end of the whole die 2. When carrying out the compound die, metal pole 6 downstream in recess 3, the both sides of whole mould 2 lower extreme are held to first U type gusset plate 43 through the metal pole 6 upper end, consolidate the support reinforcing compressive capacity to the upper end of whole mould 2, and through rotatory housing bolt 42, make its second U type gusset plate 7 that drives one end be close to towards the bottom of whole mould 2, thereby the both sides of whole mould 2 upper end are held to second U type gusset plate 7, strengthen the bottom of whole mould 2, thereby realize the reinforcing of the whole compressive capacity of whole mould 2, avoid receiving the circumstances of impact back separation.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
