Detailed description of the invention
For can technical characteristic of the present utility model and effect be described in detail, and can realize according to the content of this description, below in conjunction with accompanying drawing, embodiment of the present utility model be further illustrated.
Fig. 1 shows a kind of die casting exhaust apparatus of the present utility model, comprises body 1 and flow guiding structure.In the lump see Fig. 3 and Fig. 4, body 1 is Split type structure, it the second matrix 12 comprising the first matrix 11 and coordinate with this first matrix 11.The surface that first matrix 11 coordinates in opposite directions with the second matrix 12 has groove 111, the bottom surface of groove 111 has some along its first laterally extending lug boss 1111, these first lug bosses 1111 are adjacent formation the first groove portion 1112 between two, and groove 111 is at a sidewall tool breach 1113 of the first matrix 11.Second matrix 12 surface corresponding with the groove 111 of the first matrix 11 has the second lug boss 121, these second lug bosses 121 between two adjacent form the second groove portion 122.First lug boss 1111, first groove portion 1112 coordinates with the second groove portion 122, second lug boss 121 one_to_one corresponding and leaves gap each other respectively and forms corrugated exhaust passage 13, the breach 1113 of groove 11 and the second matrix 12 corresponding site form air inlet 131, air inlet 131 is for being communicated with the die cavity of die casting, exhaust passage 13 has the exhaust outlet 132 of being discharged by the fluid (molten metal of HTHP molten and/or gas) in it, and exhaust passage 13 is for discharging the gas in the die cavity of die casting.The elbow 3 that flow guiding structure comprises joint 2 that one end is communicated with exhaust outlet 132, one end is communicated with the other end of joint 2 and one end are communicated with the other end of elbow 3 and the other end points to first drainage tube 4 on ground downwards, like this, flow guiding structure is communicated with exhaust outlet 132, can the fluid (molten metal of HTHP molten and/or gas) in exhaust passage 13 be guided into ground, it can be avoided directly to spray and hurt sb.'s feelings.That end that first drainage tube 4 points to ground is perpendicular to the ground, to make the fluid in exhaust passage 13 (molten metal of HTHP molten and/or gas) be drawn towards ground completely as far as possible, improves protection effect.
In addition, body 1 adopts above-mentioned Split type structure, even if the first matrix 11 coordinates the gap size of the exhaust passage 13 formed not control well with the second matrix 12, such as gap is little or large (comparatively speaking, its value reality is less) affect workpiece quality, also by adjusting the first matrix 11 and the second matrix about 12 (for convenience of description, left and right only refers to the left and right shown in Fig. 1 herein, instead of restriction the utility model can only according to position shown in Fig. 1 carry out arrange use) relative movement to change the gap size of exhaust passage 13, with exhaust requirements during satisfied construction.Simultaneously due to exhaust passage 13 undulate, the hysteresis of first and second lug boss 1111,121 is subject to from the golden molten metal of the HTHP molten of air inlet 131 inflow, the amount flowing into the molten metal of exhaust passage 13 seldom and flow velocity reduce, it will soon cool down and can not flow, and can prevent liquid metal spraying from going out to hurt sb.'s feelings further.
Fig. 2 shows the another kind of die casting exhaust apparatus of the utility model, die casting exhaust apparatus difference shown in it and Fig. 1 is, its flow guiding structure is that one end is communicated with exhaust outlet 132 and the other end points to second drainage tube 5 on ground downwards, that end that this second drainage tube 5 points to ground is perpendicular to the ground, and the die casting exhaust apparatus shown in other even structure with Fig. 1 is identical.
See Fig. 1 and Fig. 2, there is in body 1 the drainage cavity 14 be communicated with exhaust passage 13, between drainage cavity 14 and exhaust passage 13, there is certain angle, such as 90 °, the molten metal of HTHP molten and/or gas flow to aforementioned angular can change direction and the volume of drainage cavity 14 is larger, the molten metal of HTHP molten in this drainage cavity 14 of inflow and/or the pressure of gas are reduced greatly, greatly can reduce the molten metal of HTHP molten or the jet velocity of gas, reduce the risk of hurting sb.'s feelings.
But, it should be noted that, the body 1 of the Split type structure that the utility model Fig. 1 to Fig. 4 presents is only one in numerous structure and can not be interpreted as it is restriction scope of the present utility model, also any other suitable structures known can be adopted, such as integral structure, also or more fraction block structure.The one in numerous structure that to be waveform be also only in exhaust passage 13 and can not be interpreted as it is restriction scope of the present utility model, also can adopt other suitable structures, as labyrinth channel etc.
The utility model also describes a kind of die casting, comprises the die casting exhaust apparatus of said structure.
It should be noted that, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any applicable mode.In order to avoid unnecessary repetition, the utility model is no longer described various possible combination.
Being described in detail the utility model above with reference to embodiment, is illustrative and not restrictive, in the change do not departed under the utility model general plotting and amendment, all within protection domain of the present utility model.
