Abstract
The invention discloses a die casting feeding barrel. The die casting feeding barrel comprises a barrel body used for being fixedly connected with a die. The barrel body is provided with a pushing chamber used for containing a die casting punch. The barrel body is provided with a feeding port. An exhaust structure used for exhausting gas is arranged at the upper portion, corresponding to the metal liquid level, of the barrel body. The exhaust structure is at least one exhaust hole communicating with the pushing chamber. The exhaust hole is located in the side, opposite to the die, of the feeding port. The die casting feeding barrel can effectively exhaust air in the die casting die, and the quality of a die casting product is guaranteed.
Description
Technical field
The present invention relates to a kind of metal casting instrument, more specifically, it relates to a kind of die casting enters
Barrel.
Background technology
Being provided with die casting chamber in traditional die casting, the cylinder of feeding cylinder arranges promotion room,
Cylinder is fixing with mould to be connected, and cylinder and die casting chamber communicate, and cylinder arranges plup inlet and conveniently adds
Enter molten metal.The pressure chamber degree of filling of traditional moulds design technology be ten five ten to five 3 percent it
Between, such as pressure chamber degree of filling is designed as 40 percent, there remains the space of 60 percent,
Gas in the space of 60 percent to enter mould together along with molten metal.At present, whole
Individual Die Casting Industry uses product tail end venting method (die venting method), i.e. design from mould
Overflow launder discharge, this will cause interiors of products because of gas be detained cause pin hole, pore, gas
The internal flaws such as bubble, leakage.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide a kind of die casting pan feeding
Cylinder, its interior air can effectively be discharged by this kind of feeding cylinder, it is ensured that the quality of die-cast product.
For achieving the above object, the technical scheme is that
A kind of die casting feeding cylinder, including for fixing the cylinder being connected with mould, described cylinder sets
Being equipped with the promotion room for placing diecasting punching head, described cylinder is provided with feeding mouth, described cylinder pair
Answer the exhaust structure being arranged over for discharging gas of metal bath surface, described exhaust structure be to
A few steam vent connected with promotion room, described steam vent is positioned at the one of feeding mouth opposing mold
Side.
Further improvement as technique scheme:
Described steam vent is tilted to set towards feeding mouth by the outer wall of the inwall of promotion room to promotion room
Put.
Described steam vent is arranged towards mold tilt by the outer wall of the inwall of promotion room to promotion room.
The method for exhausting of a kind of above-mentioned die casting feeding cylinder, irrigates when starting working in feeding mouth
Molten metal, then promotes diecasting punching head, during diecasting punching head promotion liquid level to mould, and gas
Body is gradually discharged in steam vent, when diecasting punching head continues to advance until tying after its closed grate hole
Bundle aerofluxus, exhaust work completes.
By using technique scheme, exhaust structure is set at promotion room so that people are in pressure
Directly just air can be discharged at promotion room when of casting product, allow air from least one
Steam vent in discharge；Steam vent is arranged on cylinder rather than mould, mainly considers
Air is difficult to be discharged in once entering into die casting chamber along with molten metal, and is arranged on cylinder
In, air can rise, molten metal along with the drive being increasingly towards the diecasting punching head that mould advances
Liquid level as well as rising, air the most thereon is discharged in steam vent, effectively
Ensure die-cast product quality.

Detailed description of the invention
Referring to figs. 1 through Fig. 2, die casting feeding cylinder embodiment of the present invention is described further.
As it is shown in figure 1, be the die casting feeding cylinder installation diagram with mould of the present invention, including
Mould 1, cylinder 2 and diecasting punching head 6, be provided with die casting chamber 11, institute in described mould 1
Stating cylinder 2 and arrange promotion room 21, described cylinder 2 is fixing with mould 1 to be connected, described cylinder 2
Communicate with die casting chamber 11, described diecasting punching head 6 one end constitute in being located at promotion room 21 for
Advancing the propelling end of molten metal 4, described cylinder 2 is provided with feeding mouth 5, and described cylinder 2 is corresponding
The exhaust structure being arranged over for discharging gas of molten metal 4, described exhaust structure be to
A few steam vent 3 connected with promotion room 21, described steam vent 3 is positioned at feeding mouth 5 phase
Side to mould 1.
By using technique scheme, exhaust structure is set at promotion room 21 so that people
Directly just air can be discharged at promotion room 21 die-cast product when, allow air from
Discharge in the steam vent 3 of at least one；Steam vent 3 is arranged on cylinder 2 rather than mould,
Be difficult in mainly once entering into die casting chamber 11 along with molten metal 4 in view of air by
Discharging, and be arranged in cylinder 2, air can be along with being increasingly towards the die casting punching that mould 1 advances
The drive of 6 and rise, the liquid level of molten metal 4 is as well as rising, the most gradually by it
Air discharge in steam vent 3.
In order to prevent molten metal 4 from discharging in promotion room 21, preferably described steam vent 3 by
The inwall of promotion room 21 is obliquely installed to the outer wall of promotion room 21 towards feeding mouth 5, then phase
Answer, set described steam vent 3 and be in one end of promotion room 21 outer wall as aerofluxus tail end 31,
The one end being in promotion room 21 inwall is aerofluxus head end 32, and aerofluxus tail end 31 is preferably provided at
Outside the head plate of mould, so useless have part metals liquid or drift oil or drift granule etc. to remain
During thing rubbish blocking steam vent 3, staff can clean out quickly and easily, it is ensured that die casting
The normal exhaust of mould.
Outside described steam vent 3 can certainly be allowed by the inwall of promotion room 21 to promotion room 21
Wall is obliquely installed towards mould 1.This kind of method will cause four diffusings of molten metal 4 to drop down and wave
Take, and when there being the refuse rubbish blocking steam vent 3 of the residuals such as drift oil or drift granule, work
Make personnel can not clean out quickly and easily.
When steam vent 3 is set, when the pack completeness of gear die casting chamber reaches 100%, diecasting punching head
Position in feeding cylinder is set as initial value, then towards charging on the basis of this initial value
Mouth retreats the aperture position of the aerofluxus head end 32 that 20-50 millimeter is optimal steam vent 3.
The method for exhausting with the die casting feeding cylinder of exhaust structure utilizing the present invention is as follows: start
In feeding mouth 5, irrigate molten metal 4 during work, then promote diecasting punching head 6, diecasting punching head
6 promote liquid levels to during die casting chamber 11, and gas is gradually discharged in steam vent 3,
When diecasting punching head 6 continues to advance until terminating aerofluxus after its closed grate hole 3, and exhaust work is complete
Become.
The above is only the preferred embodiment of the present invention, protection scope of the present invention not only
Being confined to above-described embodiment, all technical schemes belonged under thinking of the present invention belong to the present invention's
Protection domain.It should be pointed out that, for those skilled in the art, do not taking off
Some improvements and modifications under principle of the invention premise, these improvements and modifications also should be regarded as this
The protection domain of invention.
