The technical scheme is as follows: a thin wall dysmorphism mold insert structure, including mold insert top, mold insert base and cooling water course, the mold insert top semicircular in shape sets up on the mold insert base perpendicularly, the mold insert top becomes convex with the mold insert base on same horizontal plane, the cooling water course spanes and sets up inside mold insert top and mold insert base, the import and the export of cooling water course all are located mold insert base bottom.
Preferably, the top end of the insert and the base of the insert are in a circular arc shape on the same horizontal plane and matched with a water cooling groove of the motor end cover.
Preferably, the cooling water channel is of a special-shaped structure, and the cross section of the cooling water channel is circular, square, oval or special-shaped.
Preferably, the cooling channels do not pass through the insert tip and the fillets and corners inside the insert base.
Preferably, the insert base and the insert tip are both made of H13 hot work die steel with high hardenability and low heat treatment deformation rate.
Preferably, the insert top end, the insert base and the cooling water channel are integrally printed and formed by adopting a 3D printing technology.
Preferably, the insert base is provided with a screw mounting hole for rapidly mounting the thin-wall special-shaped insert structure on a motor end cover die.
Has the advantages that: this application prints technique integrated into one piece through 3D, and external structure is simple, and inside complicated cooling water course is easily realized through the mode that 3D printed, cools down the mold insert structure through establishing the inside cooling water course on mold insert top and mold insert base simultaneously, and then makes near the aluminium liquid of mold insert structure solidify preferentially, can solve die casting die shaping gas pocket and porosity problem to the yield of die-casting motor end cover has further been improved.

Detailed Description
The present application is further illustrated with reference to the following specific examples.
As shown in fig. 1-2, which is a schematic structural diagram of the present application, in this embodiment, the insert includes an insert top end 1, an insert base 2, and a cooling water channel 3, where the insert top end 1 is semicircular and vertically disposed on the insert base 2, and the insert top end 1 and the insert base 2 are formed in an arc shape on the same horizontal plane, and the formed arc shape matches with a water cooling groove 4 in a motor end cover.
In this embodiment, cooling water course 3 strides to set up inside mold insert top 1 and mold insert base 2, wholly become the dysmorphism structure, wherein the import and the export of cooling water course 3 all are located the bottom of mold insert base 2, the cross-section of cooling water course 3 can adopt circularly, squarely, ellipse or other dysmorphism, adopt circular cross-section in this embodiment, avoid the fillet and the too early fracture of corner of mold insert top 1 or mold insert base 2 to leak simultaneously, cooling water course 3 does not pass through inside fillet and the corner of mold insert top 1 and mold insert base 2.
In this embodiment, the insert base 2 is further provided with a screw mounting hole 5 for quickly mounting the thin-walled special-shaped insert structure on a motor end cover mold.
In the present embodiment, in order to improve the strength and the service life of the entire insert structure, the insert base 1 and the insert tip 2 are both made of H13 hot-work die steel with high hardenability and low heat treatment deformation rate, and are directly printed and formed integrally by a 3D printing technology together with the cooling water channel 3.
This embodiment is at the during operation, install on the die casting die normal water cooling groove position of motor end cover through screw mounting hole 5 fast, A department in figure 3, inject high-pressure cooling water into cooling water channel 3 when the pressure boost is accomplished to the pressure casting production pressure, ensure that the motor end cover is solidifying when in the twinkling of an eye, the whole quick cooling of mold insert structure is cooled off through the high-pressure cooling water of cooling water channel 3, and then make the aluminium liquid of mold insert structure annex solidify preferentially, thereby reach the purpose of eliminating the sealed face of normal water cooling groove 4 and the side gas shrinkage cavity of inner chamber in the motor end cover, the yield with the motor end cover has finally improved more than 15%.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent embodiments without departing from the scope of the present invention, but all the technical matters of the present invention are within the scope of the present invention.
