By adopting the technical scheme, the processing piece is hollow, because the hollow section has stronger bending resistance and stronger compression bending resistance than the solid section under the condition of the same cross section area of the column, the structural strength of the processing piece is enhanced, then the processing piece is provided with the first core bar, the second core bar and the third core bar, because the triangle has the best stability, the first core bar, the second core bar and the third core bar are arranged in a triangular mode and are mutually communicated and connected through the first rubber tube, and the first core bar, the second core bar and the third core bar are respectively connected with the inner wall of the processing piece through the second rubber tube, so that rubber flexible connections are formed between the core bars and between the three core bars and the processing piece, the rubber flexible connection structure has high internal density, can bear higher pressure, has good elastic deformation effect, further enhances the structural strength of the processing piece, and ensures that the processing piece is not easy to bend, the purpose that the strength of the magnetic core processing die is higher is achieved.

The utility model discloses further set up to: the base is provided with a fixing groove for inserting one end of a workpiece, the end, inserted into the fixing groove, of the workpiece is provided with three blind holes, the hole wall of each blind hole is provided with internal threads, the three blind holes are respectively opposite to the first core rod, the second core rod and the third core rod, the three blind holes respectively extend into the first core rod, the second core rod and the third core rod, and one side, far away from the workpiece, of the base is provided with a screw rod inserted into the blind hole.

Through adopting above-mentioned technical scheme, keep away from one side of machined part with the screw rod by the base and insert to the blind hole in, for ordinary single screwed connection, the screw rod all is fixed in the base with first core bar, second core bar and third core bar, and is more firm, has reached the more firm purpose of magnetic core processing mould. But when the user uses this product and damages the machined part, only need not hard up the screw and pull down the machined part, change new machined part can, more economic environmental protection.

The utility model discloses further set up to: the blind hole bottom is equipped with the dead lever, and the external screw thread has been arranged to the dead lever outer wall, and the one end that the screw rod was inserted to the blind hole is equipped with the locking hole, and the downthehole internal thread that is arranged of locking, dead lever insert to the locking downthehole.

Through adopting above-mentioned technical scheme, dead lever and blind hole bottom body coupling, when the user inserts the screw rod in the blind hole, not only the outer wall and the blind hole inner wall of screw rod pass through threaded connection fixedly, and the locking hole in the screw rod passes through threaded connection fixedly equally with the dead lever, and for the outer wall and the blind hole inner wall threaded connection that only singly pass through the screw rod, more firm has reached the more firm purpose of magnetic core mold processing.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 4.

The utility model discloses a concrete structure does: the utility model provides a high strength and high fastness magnetic core mold processing, includes mould 1 and bed die, goes up mould 1 and includes base 11 and two machined parts 12, machined part 12 is hollow, is equipped with first core bar 2, second core bar 3 and third core bar 4 in the machined part 12, between first core bar 2 and the second core bar 3, between second core bar 3 and the third core bar 4, all be connected through first rubber tube 5 between third core bar 4 and the first core bar 2, second core bar 3 and third core bar 4 all are connected with machined part 12 inner wall through second rubber tube 6, first rubber tube 5 and second rubber tube 6 all arrange along the equal distance of machined part 12 length direction.

Be equipped with on the base 11 and supply the 12 one end male fixed slots 7 of machined part, the one end that machined part 12 inserted fixed slots 7 is equipped with three blind hole 8, and the blind hole 8 pore wall is equipped with the internal thread, and three blind hole 8 is relative with first core bar 2, second core bar 3 and third core bar 4 respectively, and in three blind hole 8 extended first core bar 2, second core bar 3 and third core bar 4 respectively, one side that machined part 12 was kept away from to base 11 was equipped with the screw rod 9 of inserting to in the blind hole 8.
