Summary of the invention
At problems of the prior art, the object of the present invention is to provide a kind ofly increases cooling Yun Shui and logical compressed air is accelerated the cooling of hot mouth and blown disconnected initial stage wire drawing near hot mouth, thereby prevents that effectively mould that the phenomenon of wire drawing takes place from advancing glue point and preventing the wire drawing quick-break device.
The present invention is achieved in that it is included near the cooling that is provided with the hot mouth and inserts, and cooling is inserted and is provided with two kinds of anti-wire drawing quick-break technical schemes:
First kind is: described cooling is inserted and is provided with the air blowing piece, or is connected with the air blowing piece, and the air inlet pipe in an end of air blowing piece and the mould is communicated with, and the air blowing direction of the gas hole of air blowing piece is corresponding with the position of the outlet of hot mouth;
Second kind is: be provided with the fortune water pipe in described cooling is inserted, fortune water pipe one end is communicated with water inlet pipe in the mould, and the interior outlet pipe of the other end and mould is communicated with, and transports water pipe and is arranged near hot mouth exports.
The combination of preferably above-mentioned two kinds of technical schemes is provided with the fortune water pipe in described cooling is inserted, and described cooling is inserted and is provided with the air blowing piece, or is connected with the air blowing piece.
The gas hole of described air blowing piece cooling insert below, the air blowing direction of gas hole faces the gate portions of the product after the die sinking, the bottom face that cooling is inserted and the die face level of this mould, and another mould is provided with groove, during matched moulds, the gas hole of air blowing piece falls in the described groove.
