Through movable mounting ejector pin in the lower mould in this mould structure, carry out the compound die when last mould and lower mould, pour into the molten metal back into, the ejector pin stretches into the die cavity and forms the thin wall hole at end cover edge, and the pressure that produces when the ejector pin carries out the jacking can guarantee that the molten metal at die cavity edge carries out evenly distributed to form the thin wall hole smoothly.
Description
Technical Field
The utility model relates to a storage battery car end cover mould.
Background
Pressure casting, referred to as die casting, is a casting method in which molten alloy liquid is poured into a pressing chamber, a cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. The end cover 7 shown in fig. 2 and 3 is generally formed by die casting aluminum, thin-wall holes 71 are distributed at the edge of the end cover 7, in the currently used mold structure, a convex portion is mainly arranged at the lower mold for forming the thin-wall holes, and because the convex portion is smaller in thickness and is located at the edge of the cavity, the molten metal at the edge is easily unevenly distributed due to the existence of the convex portion, so that the forming of the thin-wall holes is affected.
SUMMERY OF THE UTILITY MODEL
To the weak point that exists in the above-mentioned problem, the utility model provides a storage battery car end cover mould.
In order to realize the above-mentioned purpose, the utility model provides a storage battery car end cover mould, including last mould, lower mould, go up the mould with the lower mould department of meeting forms the die cavity of end cover, go up the mould with lower mould edge connection department forms the discharge port, the lower mould is close to edge central symmetry processing and has the guiding hole to run through to the die cavity, install the ejector pin in the guiding hole, the ejector pin can along the guiding hole slides from top to bottom, ejector pin upper portion stretches into form in the die cavity the thin wall hole of end cover.
As the utility model discloses further improve, the ejector pin lower part is stretched out the guiding hole and is connected the lifter plate, climbing mechanism is connected to the lifter plate bottom.
As the utility model discloses further improve, it is equipped with the runner connection to go up the mould middle part the die cavity.
The utility model has the advantages that:
through movable mounting ejector pin in the lower mould in this mould structure, carry out the compound die when last mould and lower mould, after pouring into the molten metal at a high speed through the runner, the ejector pin stretches into the die cavity and forms the thin wall hole at end cover edge, and the pressure that produces when the ejector pin carries out the jacking can guarantee that the molten metal of die cavity edge carries out evenly distributed to form the thin wall hole smoothly.

In the figure: 1. an upper die; 11. a gate; 2. a cavity; 3. a lower die; 31. a guide hole; 4. a top rod; 5. a lifting plate; 6. a jacking mechanism; 7. an end cap; 71. a thin wall hole; 8. and (7) discharging the air.
Detailed Description
As shown in figure 1, a storage battery car end cover mould, including last mould 1, lower mould 3, go up mould 1 and 3 department of meeting of lower mould and form the die cavity 2 of end cover 7, it forms discharge port 8 to go up 3 edge connection departments of mould 1 and lower mould, it is equipped with runner 11 and connects die cavity 2 to go up 1 middle part of the mould, lower mould 3 is close to edge central symmetry and processes and has guiding hole 31 to run through to die cavity 2, installation ejector pin 4 in the guiding hole 31, ejector pin 4 can slide from top to bottom along guiding hole 31, ejector pin 4 upper portion stretches into the thin wall hole 71 that forms end cover 7 in the die cavity 2, ejector pin 4 lower part stretches out guiding hole 31 and connects lifter plate 5, jacking mechanism 6 is connected to lifter plate 5 bottom.
Through movable mounting ejector pin in the lower mould in this mould structure, carry out the compound die when last mould and lower mould, pour into the molten metal back into, the ejector pin stretches into the die cavity and forms the thin wall hole at end cover edge, and the pressure that produces when the ejector pin carries out the jacking can guarantee that the molten metal at die cavity edge carries out evenly distributed to form the thin wall hole smoothly.
When in specific use, the utility model is described with the attached drawings for the convenience of understanding;
as shown in fig. 2 and fig. 3, thin-walled holes 71 are symmetrically distributed at the edge of the end cover 7, and the end cover 7 is generally formed by aluminum die casting.
During the die-casting molding, the ejector pin is initially located at the low position of the cavity and is flush with the concave surface on the upper portion of the lower die (see fig. 4), the upper die and the lower die are assembled, molten metal is firstly filled into the cavity at a low speed and then filled into the cavity at a high speed through the pouring gate, a push rod is arranged in the pouring gate to pressurize the molten metal in the cavity, the molten metal is filled in the whole cavity, meanwhile, the jacking mechanism works, the lifting plate drives the ejector pin to move upwards along the guide hole, the upper portion of the ejector pin extends into the cavity until the top of the ejector pin is contacted with the upper die, so that a thin-wall hole is formed after die-casting, an upward jacking force is generated on the molten metal around the ejector pin in the lifting process of the ejector pin, the molten metal at the position is diffused around the ejector pin, and the molten metal around the thin-wall hole can be uniformly distributed.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
