Abstract

The utility model discloses a feed cylinder is gone into in die -casting, include the barrel that is used for with mould fixed connection, the barrel is provided with the propulsion room that is used for placing the die -casting drift, the barrel is equipped with the pan feeding mouth, the top that the barrel corresponds the metal bath surface is equipped with the exhaust structure who is used for exhaust gas, the exhaust hole that exhaust structure is at least one and impels the room intercommunication, exhaust hole site in one side of the relative mould of pan feeding mouth. This kind of feed cylinder is gone into in die -casting can be effectual with the air escape in the die casting die, guarantee the quality of die -casting product.

Description

Die casting feeding cylinder

Technical field

This utility model relates to a kind of metal casting instrument, more specifically, it relates to a kind of pressure It is cast into 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.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is to provide a kind of die casting Feeding cylinder, its interior air can effectively be discharged by this kind of feeding cylinder, it is ensured that die-cast product Quality.

For achieving the above object, this utility model provides following technical scheme:

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.

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, this utility model die casting feeding cylinder embodiment is described further.

As it is shown in figure 1, be the installation diagram of die casting feeding cylinder of the present utility model and mould, wherein Including mould 1, cylinder 2 and diecasting punching head 6, in described mould 1, it is provided with die casting chamber 11, Described cylinder 2 arranges promotion room 21, and described cylinder 2 is fixing with mould 1 to be connected, described cylinder Body 2 and die casting chamber 11 communicate, and described diecasting punching head 6 one end is constituted 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, described cylinder 2 The exhaust structure being arranged over for discharging gas of corresponding molten metal 4, described exhaust structure The steam vent 3 connected with promotion room 21 at least one, described steam vent 3 is positioned at feeding mouth 5 The side of opposing mold 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.

Utilize the method for exhausting with the die casting feeding cylinder of exhaust structure of the present utility model as follows: In feeding mouth 5, irrigate molten metal 4 when starting working, then promote diecasting punching head 6, die casting Drift 6 promotes liquid level to during die casting chamber 11, and gas is gradually arranged in steam vent 3 Go out, when diecasting punching head 6 continues to advance until terminating aerofluxus, aerofluxus work after its closed grate hole 3 Complete.

The above is only preferred implementation of the present utility model, protection model of the present utility model Enclosing and be not limited merely to above-described embodiment, all technical schemes belonged under this utility model thinking are equal Belong to protection domain of the present utility model.It should be pointed out that, the ordinary skill for the art For personnel, without departing from the some improvements and modifications under this utility model principle premise, these Improvements and modifications also should be regarded as protection domain of the present utility model.
