Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present invention, a mold for rapidly changing a mold for a step roller includes a base 1, a ring of blank ring 3 is disposed inside the base 1, a blank column 4 is disposed at the center inside the base 1, an annular container is formed between the blank ring 3 and the blank column 4, a connection column 6 is fixed on the base 1, the connection column 6 is slidably connected to a gland 2, the gland 2 and the annular container can form a closed space, a filling opening 5 is disposed on the gland 2, and the filling opening 5 is communicated with the annular container through a plurality of material distribution openings 51.

In this embodiment, the side of the gland 2 is provided with a coolant inlet 7, the side of the base 1 is provided with a coolant outlet 8, and after the gland 2 is attached to the base 1, the coolant inlet 7 is communicated with the coolant outlet 8. The blank in the base 1 can be cooled by circulating a cooling fluid through the cooling fluid inlet 7 and the cooling fluid outlet 8.

In this embodiment, the blank ring 3 is rotatably connected to the base 1, and the blank pillar 4 is rotatably connected to the base 1. The embryo body can be quickly separated from the base 1 by rotating the embryo ring 3 and the embryonic column 4.

In this embodiment, base 1 is equipped with knob 9 in the front, knob 9 is connected with screw rod 10 in the base 1, fixed cover is equipped with helical gear 11 on the plumule 4, helical gear 11 and screw rod 10 threaded connection can drive the plumule 4 through rotatory knob 9 and rotate.

In this embodiment, a central gear 12 is further fixedly sleeved on the embryonic column 4, the central gear 12 is meshed with a transmission gear 13, the transmission gear 13 is meshed with a first driven gear 14, a second driven gear 15 is coaxially and fixedly connected with the first driven gear 14, a ring of gear ring 16 is fixed outside the embryonic ring 3, and the gear ring 16 is meshed with the second driven gear 15. That is, when the pillars 4 rotate, the ring 3 is synchronously driven to rotate, and the rotation directions of the pillars 4 and the ring 3 are opposite, so that the inner and outer parts of the embryo body are rapidly separated from the base 1 by the reverse torque.

In this embodiment, a plurality of cooling water channels 31 are distributed on the circumference of the sidewall of the blank ring 3, the cooling water channels 31 are vertically through, a circle of injection groove 71 is formed below the gland 2, the injection groove 71 is communicated with the cooling liquid inlet 7, a circle of discharge groove 81 is formed on the base 1, the discharge groove 81 is communicated with the cooling liquid outlet 8, and the injection groove 71 and the discharge groove 81 correspond to the cooling water channels 31.
