Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1.

The application discloses forming die of metal rubber coating sealing member includes:

the mold core 1 is provided with a lower insert 5 which provides a stress base and is provided with a through hole in the middle;

the mold core comprises a core 1 arranged on a lower insert 5, wherein the interior of the core 1 is a hollow forming space 11, a mounting table 12 is integrally formed and fixed on the periphery of the core 1, and the core 1 is arranged on the lower insert 5 through the mounting table 12;

an operation part 13 is integrally formed and fixed at the top of the core 1, a groove 14 which is convenient for operating the operation part 13 is arranged on the operation part 13, and the groove 14 is annularly arranged at the periphery of the operation part 13 of the core 1.

When the core 1 is separated from the lower insert 5, the core 1 is rapidly separated from the lower insert 5 through the operation part 13 under the force applied by the groove 14, so that the problem that the separation operation is not performed under the force when the core 1 with the smooth conical surface at the top end of the core 1 is separated from the lower insert 5 is solved.

The lower insert 5 is in contact with the core 1 with a tapered surface.

Still include lower bolster 4, the lower bolster 4 middle part is equipped with the through-hole, and lower insert 5 is installed in the through-hole in the middle part of

lower bolster

4, and 5 upper portion spacing cards of lower insert are at the lower bolster 4 top.

The mold core is characterized by also comprising an upper insert 2 with a through hole in the middle, wherein the upper insert 2 is correspondingly installed with the installation platform 12 of the mold core 1; the upper insert 2 is in contact with the core 1 with a tapered surface, and the core 1 is pressed against the lower insert 5 by the upper insert 2.

The mold also comprises an upper template 3 with a through hole in the middle, and the upper template 3 is pressed on the periphery of the upper insert 2; the upper template 3 is positioned and assembled with the lower template 4 through the positioning pin 6, the upper insert 2, the lower insert 5 and the core 1 form a whole die by the upper template 3 and the lower template 4, and metal encapsulation molding of the metal piece in the molding space 11 inside the core 1 at the later stage is facilitated.
