Description
Technical Field
The invention relates to a pouring cup capable of containing molten metal and a mold thereof, in particular to an aluminum liquid pouring cup applied to a turnover type gravity casting external mold and a mold assembly applied to the aluminum liquid pouring cup.
Background
The engine cylinder cover casting is an important component in the casting pouring process, the aluminum liquid has the main function of providing aluminum alloy materials for various cylinder cover castings, and the temperature of the aluminum liquid in the cylinder cover pouring process is the most important ring for ensuring that the produced castings do not have casting defects such as shrinkage cavities and shrinkage porosity. In the casting process of the aluminum liquid temperature, the more stable the aluminum liquid temperature is, the less the temperature loss is, and the less casting defects such as shrinkage cavities and shrinkage porosity of products are generated. At present, the most common aluminum liquid pouring cup on the metal outer mold of the cylinder cover is a casting cup of a founding part or a pouring cup directly welded by a thick steel plate, and the structural form of a pouring cup inner container is not adopted. Therefore, the temperature of the aluminum liquid must be increased to meet the requirement of product filling type, but the temperature of the aluminum liquid is increased, so that energy is wasted, and the risk of shrinkage cavity and shrinkage porosity defects of the product quality is increased; and the casting cup is cooled quickly, so that a very thick and large number of alumina skins are generated, and the cost of the cylinder cover casting is increased.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides the heat-preservation pouring cup for the turnover gravity casting external mold and the stamping mold assembly applied by the heat-preservation pouring cup, which have the advantages of energy conservation, good heat-preservation effect, reduction of aluminum cost, simple manufacturing process and improvement of product quality.
The purpose of the invention is realized by the following technical scheme: the heat-preservation pouring cup for the turnover gravity casting external mold comprises a shell, wherein a pouring cup inner container is arranged in the shell through a heat-preservation asbestos layer, and a supporting plate is arranged at the edge of the top of the shell.
The shell and the supporting plate are arranged at the inlet of aluminum liquid on the applied metal outer mold through a connecting plate.
The stamping die assembly applied to the heat-preservation pouring cup for the turnover gravity casting external die comprises an upper die and a lower die, wherein a liner core is arranged on the lower die, a lower movable die plate is arranged on the lower die and penetrates through the liner core, the lower movable die plate is connected with a top plate through a guide post penetrating through the lower die, an upper die forming plate is arranged below the upper die, and upper die forming inner cavities corresponding to the liner core are formed in the upper die and the upper die forming plate.
After the structure of the invention is adopted, the pouring cup is formed by combining a pouring cup inner container (stainless steel material) as an inner layer, a heat-preservation asbestos layer as a middle layer, a shell (steel material) as an outer layer and the like in three layers, and the heat-preservation pouring cup is arranged at an aluminum liquid inlet of a riser of a metal external mold and is fixed on a connecting plate. Pouring the aluminum liquid into the heat-preservation pouring cup by a mechanical arm or a manual work, and slowly turning over the metal external mold installation machine table to allow the aluminum liquid to flow into the cavity of the metal external mold. Because of the effective heat preservation effect of the inner container of the pouring cup and the heat preservation asbestos layer, the temperature of the aluminum liquid in the heat preservation pouring cup is stable, the heat dissipation is less, the surface of the aluminum liquid possibly has a very small amount of alumina cortex, and the alumina cortex can be blown into the casting riser by using the air flow for light blowing, so that the useless alumina cortex can not be generated. Compared with the prior art, the invention has the advantages of high efficiency, energy saving, good heat preservation effect of the aluminum liquid, product cost reduction, low investment cost of the pouring cup, one-step forming of punching and manufacturing of the inner container of the pouring cup, simple and practical process and improvement of the yield of produced casting products.

FIG. 1 is a schematic structural view of the present invention in which a thermal cup is integrally mounted on a metal outer mold.
FIG. 2 is a schematic structural view of a one-shot forming type pouring cup liner stamping die assembly applied to the heat preservation pouring cup of the present invention.
Detailed Description
Referring to fig. 1, the heat-preservation pouring cup for the turnover gravity casting external mold comprises a shell 1 (a welding part), a pouring cup liner 2 is arranged in the shell 1 through a heat-preservation asbestos layer 5, namely the heat-preservation asbestos layer 5 is arranged between the periphery of the pouring cup liner 2 and the inner wall of the shell 1, and a support plate 3 (a molten aluminum inlet 7 close to a metal external mold 6) is arranged at the top edge of the shell 1. The shell 1 and the supporting plate 3 are arranged at an aluminum liquid inlet 7 on an applied metal outer die 6 through a connecting plate 4 (which is beneficial to accurate casting and has good stability).
The heat-preservation pouring cup has good heat preservation, the mold can be directly poured after being heated without heating again, the original pouring cup needs to be heated for 20-30 minutes, otherwise the temperature loss of the aluminum liquid is large (each cylinder cover uses less aluminum liquid about 150 grams), the temperature of the aluminum liquid is more stable, the temperature loss is less, the casting defects such as shrinkage cavity and shrinkage porosity of the product are less, and the manufacturing cost of the heat-preservation pouring cup is low.
As shown in fig. 2, the one-step forming type pouring cup liner stamping die assembly for manufacturing a pouring cup liner of the heat preservation pouring cup comprises an upper die 201 (the upper die is connected with a stamping power source punch), a lower die 206 (arranged on a lower die foot 207 and a lower die foot plate 208), a liner core 204 arranged on the lower die 206, a lower movable die plate 205 arranged on the lower die 206 and penetrating through the liner core, the lower movable die plate 205 connected with a top plate 210 (the top plate is connected with an upper top power source cylinder) through a guide post 209 penetrating through the lower die, an upper die forming plate 203 arranged below the upper die 201, and an upper die forming cavity 202 corresponding to the liner core 204 are arranged in the upper die 201 and the upper forming die plate 203.
First, the lower die plate 205 is raised above the liner core 204 and below the upper die forming plate 203, and the top plate 210 is placed close to the lower die 206, and the stainless steel plate is laid on the lower die plate and above the liner core. Then, the punch press driven by the punching power source drives the upper mold 201 and the upper mold forming plate 203 to press the lower mold plate, and presses the lower mold plate, the guide post and the top plate downward, so that the top plate is gradually separated from the lower mold, and the stainless steel plate is pressed into the upper mold forming cavity 202 formed in the upper mold 201 and the upper mold forming plate 203 by the inner container core 204 to be formed, thereby the finished product of the inner container of the pouring cup is manufactured by punching. And finally, the upper die and the upper die forming plate are lifted upwards to be separated from the liner core, the upper jacking power source oil cylinder drives the top plate upwards and then enables the lower movable die plate to be lifted through the guide post, so that the finished product of the inner container of the pouring cup is lifted upwards to be separated from the liner core, and finally the finished product of the inner container of the pouring cup is taken down.
