Abstract
The invention discloses an improved exhaust mode for a pressure casting die. The improved exhaust mode comprises broadening the caliber of an exhaust passage, increasing the diameters of an exhaust plug and the exhaust passage, and applying active cooling on the exhaust plug when casting media overflows along the exhaust passage. The invention further discloses an exhaust device for the pressure casting die. A mold cavity is provided with the exhaust plug, the diameters of the exhaust plug and the exhaust passage range from 1 mm to 2 mm, and the exhaust plug is provided with a cooling device.
Description
Technical field
The present invention relates to a kind of casting mould exhaust mode and device, relate to specifically die casting die exhaust mode and device.
Background technology
In the compression casting field, die venting effect quality directly affects casting quality.Exhaust does not freely cause the die cavity back-pressure, causes the defectives such as misrun, volume gas, particularly in compression casting, the Mold Making precision is high, foundry media is filled mold cavity under certain pressure, die venting needs unobstructed, guarantees that again foundry media can not leak outside by gas extraction system simultaneously.So in die casting die, generally adopt the slight gap structures such as venting plug, exhaust line to carry out exhaust, such exhaust structure can only slightly weaken the die cavity back-pressure, exhaust is slow, particularly embodies obviously in high-pressure casting or low pressure massive casting.
Summary of the invention
The problem that the present invention solves is to provide a kind of die casting die exhaust mode and device with refrigerating function, exhaust passage smoothly can be provided, simultaneously foundry media can not leak outside again, and exhaust is slow to solve, mold cavity back-pressure, foundry media leak outside etc. affects the problem of casting quality.
The improved pressure mould exhaust mode of the present invention is: widen the exhaust passage bore, increase venting plug exhaust passage diameter, when foundry media in-line arrangement gas passage is excessive, apply active cooling on venting plug.
The improved pressure mould device of the present invention is: mold cavity arranges venting plug, venting plug exhaust passage diameter is 1mm-2mm, and venting plug arranges cooling device, when foundry media in-line arrangement gas passage is excessive, cooling device prevents that with the foundry media cooled and solidified foundry media from overflowing.
As the preferred embodiment of the present invention: the exhaust passage comprises exhaust input hole, exhaust delivery outlet, and the exhaust input hole directly is communicated with mold cavity, and the exhaust delivery outlet directly is communicated with peripheral atmosphere, and the diameter of exhaust input hole, exhaust delivery outlet is 1mm-2mm.Cooling device comprises cooling input cavity, cooling output cavity, exhaust cavity, cooling tube, cooling input cavity is connected by taper pipe thread with cooling output cavity, cooling output cavity is connected by taper pipe thread with the exhaust cavity, cooling tube is connected with cooling input cavity by welding, and cooling tube is deep in the exhaust cavity.
Directly connect by taper pipe thread between cooling input cavity, cooling output cavity, exhaust cavity, effectively avoid cooling medium leakage problem under high temperature, simplify simultaneously attended operation.The exhaust cavity can keep the relative low temperature state under the cooling medium of cooling tube input is cooling, like this, the diameter of exhaust input hole can be much larger than the gap of conventional venting plug in die casting die, diameter is got 1mm to 2mm, make the smooth and easy eliminating of gas of mold cavity, can lower the temperature rapidly during the exhaust of high temperature foundry media contact simultaneously input hole and solidify, effectively avoid foundry media to leak outside, and then can effectively improve the casting flaw of freely not being with due to die venting, promote the quality of foundry goods and the stability of castings production.
Benefit of the present invention is, can provide the venting plug structure that a kind of exhaust is smooth and easy efficiently, foundry media does not leak outside for die casting die, reduces the casting flaw that casting process freely is not with due to die venting, promotes the quality of foundry goods and the stability of castings production.

The specific embodiment
The improved pressure mould exhaust mode of the present invention is: widen the exhaust passage bore, increase venting plug exhaust passage diameter, when foundry media in-line arrangement gas passage is excessive, apply active cooling on venting plug.
The improved pressure mould device of the present invention is: mold cavity arranges venting plug, venting plug exhaust passage diameter is 1mm-2mm, and venting plug arranges cooling device, when foundry media in-line arrangement gas passage is excessive, cooling device prevents that with the foundry media cooled and solidified foundry media from overflowing.
As the preferred embodiment of the present invention: this is shown in Figure 1, the exhaust passage comprises exhaust input hole 5, exhaust delivery outlet 6, exhaust input hole 5 directly is communicated with mold cavity, and exhaust delivery outlet 6 directly is communicated with peripheral atmosphere, and the diameter of exhaust input hole 5, exhaust delivery outlet 6 is 1mm-2mm.Cooling device comprises cooling input cavity 1, cooling output cavity 2, exhaust cavity 3, cooling tube 4, cooling input cavity 1 is connected by taper pipe thread with cooling output cavity 2, cooling output cavity 2 is connected by taper pipe thread with exhaust cavity 3, cooling tube 4 is connected with cooling input cavity 1 by welding, and cooling tube 4 is deep in exhaust cavity 3.
