Abstract

The utility model relates to a pouring gate for a magnesium alloy vehicle door die-casting die. The pouring gate comprises a pouring gate body connected with a pressure chamber and flow gates connected to the pouring gate body. The pouring gate body comprises a left pouring gate and a right pouring gate, the left pouring gate and the right pouring gate are connected in parallel to the outer side of the pressure chamber so that an m shape can be formed by the left pouring gate and the right pouring gate, the pressure chamber is located at the bottom end of the middle of the m shape, the flow gates are continuously distributed at the edge of the outer side of the left pouring gate and the edge of the outer side of the right pouring gate, and the overall length of the pouring gate body is not smaller than 1000 mm. The pouring gate body is located in the middle of a product frame and is of the m shape, the pressure chamber is located at the bottom end of the middle of the m shape, molten magnesium enters the left pouring gate and the right pouring gate at the same time in a center feeding mode, the filling time is shortened, and the length of the pouring gate body is not smaller than 1000 mm, so that the length and the area of each flow gate outside the pouring gate body are increased along with the increase of the length of the pouring gate body, the molten magnesium enters a cavity more rapidly, and the filling time is greatly shortened. The pouring gate can be suitable for die-cast formation of a magnesium alloy vehicle door.

Description

A kind of running channel of magnesium alloy car door die casting
Technical field
The utility model relates to a kind of running channel, particularly relates to a kind of running channel of magnesium alloy car door die casting.
Background technology
Magnesium alloy door lock striker plate as shown in Figure 1, this door lock striker plate size is larger, and its length exceedes 1 meter, and width exceedes 800mm, and therefore great majority are by punch forming sheet metal component.But punch forming has the unfavorable factor such as the difficulty of manufacture, many, the complex process of operation, can have a strong impact on production efficiency.For this reason, technical staff wishes to produce door lock striker plate with die cast, its utilization be die cast dimensional accuracy high, complex-shaped part is processed to feature easily, production efficiency is improved.
For this super-huge thin-wall part of door lock striker plate, because magnesium liquor ratio aluminium liquid is more easily oxidized, how to shorten filling flow process, be exactly the die casting key issue to be solved of magnesium alloy door lock striker plate.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is to provide a kind of running channel of magnesium alloy car door die casting, and this running channel has shortened the filling time of magnesium liquid greatly, makes die casting be applied to the moulding of door lock striker plate.
The technical scheme that the utility model adopts is:
A kind of running channel of magnesium alloy car door die casting, comprise the running channel body that is connected with pressure chamber, be connected to the ingate on running channel body, described running channel body comprises left running channel and right running channel, described left running channel is connected in pressure chamber outside in parallel with right running channel makes running channel become class " m " font, pressure chamber is positioned at the bottom at " m " word middle part, described ingate is along the outer ledge continuous distributed of left running channel and right running channel, and the overall length of described running channel body is not less than 1000mm.
As the further improvement of technique scheme, the cross section of described pressure chamber is circular, and this circular diameter is 100~200mm, and the area of described ingate is 1600mm~2500mm.The area of ingate is larger, and the amount that magnesium liquid flows out from ingate is simultaneously more, can effectively shorten the filling time, shortens the time of contact of magnesium liquid and air, reduces the generation of oxide, improves product surface quality.And the area of pressure chamber and ingate can reduce ingate flow velocity within the scope of certain proportion, minimizing is washed away mould, guarantees the life-span of mould.
As the further improvement of technique scheme, the difference of the length of described left running channel and right running channel is not more than 100mm, makes magnesium liquid within the roughly the same time, be full of two running channels, keeps the synchronism of cast.
The beneficial effects of the utility model are: running channel body of the present utility model is positioned at the middle part of product framework and is class " m " type, pressure chamber is positioned at the bottom at " m " word middle part, the mode of this central feeding makes magnesium liquid can enter left running channel and right running channel simultaneously, shorten the filling time, and the length of running channel body is not less than 1000mm and makes at the length of the ingate in running channel body outside and area also thereupon elongated and become large, it is faster that magnesium liquid enters the speed of die cavity, filling time shortens greatly, has solved the magnesium liquid defect that easily oxidation brings product quality in press casting procedure.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the schematic diagram of door lock striker plate;
Fig. 2 is top view of the present utility model;
Fig. 3 is axonometric drawing of the present utility model;
Fig. 4 is casting schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, in the present embodiment, the door lock striker plate appearance and size of the casting of: 1203 mm × 844mm × 172mm, wall thickness is 2mm only, and foundry goods single-piece only weighs 2.65 Kg, is especially big automobile die casting thin-walled parts, adopts magnesium alloy materials.
In order to cast this door lock striker plate, use the running channel of magnesium alloy car door die casting as shown in Figure 2, Figure 3 and Figure 4.Comprise the running channel body that is connected with pressure chamber 1, be connected to the ingate 2 on running channel body, running channel body comprises left running channel 3 and right running channel 4, left running channel 3 is connected in pressure chamber 1 outside in parallel with right running channel 4 makes running channel become class " m " font, pressure chamber 1 is positioned at the bottom at " m " word middle part, and ingate 2 is along the outer ledge continuous distributed of left running channel 3 and right running channel 4.The overall length of running channel body is not less than 1000mm.
Magnesium liquid is divided into two-way after flowing out from pressure chamber 1 and enters left running channel 3 and right running channel 4 simultaneously, when magnesium liquid is full of after running channel body, from entering in die cavity cooling with the roughly the same ingate 2 of running channel body length.Because the running channel body adopting is longer, can reduce the consumption of magnesium material.
In the present embodiment, the long 770mm of left running channel 3, the long 750mm of right running channel 4, the difference of both length is not more than 100mm, make magnesium liquid within the roughly the same time, be full of two running channels on the one hand, keep the synchronism of cast, on the other hand, can effectively reduce the loss of heat, be conducive to fill the magnesium liquid maintenance higher temperature of the die cavity of entering.
Because ingate 2 is along the outer ledge continuous distributed of left running channel 3 and right running channel 4, making foundry goods 3/4 region is on shorter the filling distance, and this is extremely beneficial to filling.
In the present embodiment, the cross section of pressure chamber 1 is circular, pressure chamber 1 diameter is 160mm, and ingate 2 areas are 2150mm2, the filling time can be pressed in 1.5s, shorten the time of contact of magnesium liquid and air, reduce the generation of oxide, improve product surface quality, and reduced ingate 2 speed, minimizing is washed away mould, guarantees the life-span of mould.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
