Detailed Description
Referring to fig. 1 and 2, the present invention provides a sealing ring forming mold, including: an upper template 2 and a lower template 1;
the bottom surface of the upper template 2 is provided with a plurality of second ring grooves 21, the plurality of second ring grooves 21 are sleeved layer by layer, and the inner diameter of the second ring grooves 21 is gradually increased from inside to outside;
a pouring gate is arranged at the position, corresponding to each second ring groove 21, on the top surface of the upper template 2, and a pouring gate 22 connected with the corresponding second ring groove 21 is arranged on the bottom surface of the pouring gate;
the top surface of the lower template 1 is provided with a plurality of first ring grooves 11, the first ring grooves 11 are sleeved layer by layer, and the inner diameter of the first ring grooves 11 is gradually increased from inside to outside;
the plurality of first ring grooves 11 and the plurality of second ring grooves 21 are arranged in a one-to-one correspondence manner, and after the upper template 2 and the lower template 1 are matched, the first ring grooves 11 and the corresponding second ring grooves 21 form an annular cavity for forming a sealing ring.
When the die is used specifically, the upper die plate 2 and the lower die plate 1 are matched, so that the casting material can be poured into a cavity with the required production size from a corresponding pouring gate and a pouring channel 22; and after the pouring is finished and the sealing ring is cooled or is cooled for a period of time by an external cooling device, the upper template 2 and the lower template 1 are opened to obtain the sealing ring with the required size. The utility model can produce sealing rings with different specifications on the same die, thereby greatly reducing the production cost of large-size sealing rings.
In this embodiment, the difference between the inner and outer diameters of the first ring grooves 11 is equal.
In this embodiment, the upper template 2 and the lower template 1 are correspondingly provided with a positioning pin hole 23, and the positioning pin hole 23 is used for realizing the stacking and fastening of the upper template 2 and the lower template 1.
Referring to fig. 3, in the present embodiment, a dead head 24 is connected between the runner 22 and the corresponding second annular groove 21. Therefore, the liquid can be conveniently supplemented, and the feeding efficiency can be improved.
In a further embodiment, the runner 22 comprises a sprue disposed at the bottom of the gate and a runner 221 connected between the sprue and the blank holder 24.
In this embodiment, the blank-holding riser 24 is in a shape of a circular truncated cone with a small top and a large bottom, the top end of the blank-holding riser 24 extends above the upper mold plate 2, and the bottom end of the blank-holding riser 24 and the top of the corresponding second ring groove 21 are partially overlapped in the vertical direction to form a liquid inlet channel for communicating the two.
