Abstract
The utility model discloses a die with a nitrogen flushing device. The die comprises a die body, wherein a die cavity is formed in the center of the die body; gas channels are formed at the periphery of the die cavity in the die body; a gas inlet which extends inwards and is communicated with the gas channels is formed in the outer side of the die body; ventilation holes which extend outwards and are communicated with the gas channels are formed in the wall of the die cavity; a nitrogen nozzle is sleeved on the gas inlet; and a gas inlet of the nitrogen nozzle is connected with a nitrogen source through a pressure reduction gauge. According to the die, the gas channels are formed in the die body and provided with the gas inlet communicated with the external world and the ventilation holes communicated with the die cavity, and the nitrogen nozzle is sleeved on the gas inlet and connected with the nitrogen source through the pressure reducing gauge, so that nitrogen can be charged into the die cavity, air in the die cavity can be expelled, a phenomenon that a formed product reacts with oxygen in the air can be effectively avoided, and the quality of the formed product can be effectively improved.
Description
Technical field
The utility model relates to a kind of production mould, relates in particular to a kind of mould with nitrogen blowing device.
Background technology
Press the difference of the material of institute's moulding, mould can be divided into metal die and nonmetal mould, wherein metal die is divided into again: casting mould, diel and forging mold etc., no matter the mould that is what type all can produce heat in shaped article, if the untimely quality that can affect product of leading away of these heats, in addition, in the situation that high temperature, if the mould the inside has a large amount of air, product meeting and airborne oxygen react, and cause the Quality Down of product.
The utility model content
The purpose of this utility model is to provide a kind of mould with nitrogen blowing device, to solve in prior art the problem because existing product quality that air causes to descend in die cavity.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of mould with nitrogen blowing device, comprise mold, the centre of mold has die cavity, be provided with air flue in the periphery of described die cavity in described mold, offer the air inlet that extends internally and be communicated with described air flue on the lateral surface of mold, offer the blow vent that stretches out and be communicated with air flue on the chamber wall of described die cavity, be inserted with the nitrogen nozzle on described air inlet, the air inlet of nitrogen nozzle is connected with the nitrogen source of the gas by decompression table.
Described air flue comprises the first annular air channel and the second annular air channel, two annular air channels arrange with one heart and the first annular air channel is in the outer ring, be provided with the communicating passage that both are communicated with between two annular air channels, described air inlet by with the first annular air channel between be communicated with described air flue and be communicated with, described blow vent by with the second annular air channel between be communicated with described air flue and be communicated with.
Described nitrogen source of the gas is the nitrogen gas cylinder.
Be provided with air flue in mold of the present utility model, air flue has the air inlet that is in communication with the outside and the blow vent that is communicated with die cavity, be inserted with the nitrogen nozzle on air inlet, the nitrogen nozzle is connected with the nitrogen source of the gas by decompression table, can be filled with nitrogen in die cavity like this, air in die cavity is driven away, can prevent effectively that the product and the airborne oxygen that form out from reacting, and can effectively improve by the quality of shaped article.
In addition, constantly be blown into cold nitrogen in air flue, the heat that produces in the time of can taking away a part of moulding is conducive to cooling by shaped article.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
The specific embodiment
A kind of embodiment with mould of nitrogen blowing device, in Fig. 1, its mold 1 integral body is cylindrical, is provided with die cavity 5 in the centre of mold 1.Be provided with air flue in mold 1, air flue is in the periphery of die cavity.The air flue here is divided into the first annular air channel 2 and the second annular air channel 3, two annular air channels arrange with one heart, and wherein the first annular air channel 2 is in the outer ring, and namely the length of the first annular air channel 2 is longer than the length of the second annular air channel 3.Be communicated with between the first annular air channel 2 and the second annular air channel 3 and be provided with four communicating passage 10, one end of these four communicating passage 10 is communicated with the first annular air channel 2, the other end is communicated with the second annular air channel 3, four communicating passage 10 are uniform in a circumferential direction, offer air inlet on the lateral surface of mold 1, air inlet extends internally and is communicated with the first annular air channel 2.Offer the blow vent 9 that stretches out and be communicated with the second annular air channel 3 on the wall of the chamber of die cavity 5.The die cavity here is square die cavity, and blow vent 9 one has 8, and wherein four blow vents are in the middle part of four sidewalls of die cavity, and other four blow vents are in the place, four angles of die cavity sidewall.Be inserted with nitrogen nozzle 8 on air inlet, the air inlet of nitrogen nozzle 8 is connected with the outlet of decompression table 6 by pipeline 7, and the import of decompression table 6 is connected with the outlet of nitrogen gas cylinder 4.
Air flue in the present embodiment is that the form of air flue also only is confined to above-mentioned form in practice, also can be rectangle due to the air flue of the concrete form of two annular air channels compositions, oval or annular air channel.
Nitrogen source of the gas in the present embodiment is the nitrogen gas cylinder, can be also other forms of source of the gas.
