Description

Low-defect lost foam casting system for producing automobile stamping die

Technical Field

The utility model relates to an automobile stamping die casting field especially relates to a low defect disappearance mould casting system for producing automobile stamping die.

Background

The furan resin lost foam casting is a technological method for directly molding a foam model with the size similar to that of a product and obtaining a target casting through pouring, and the method can improve the dimensional precision of the casting, simplify the molding process and the like. The lost foam casting male die has extremely high technical requirements as important equipment for producing the stamping die, and in the past, in the manufacturing process, the surface and near-surface defects are formed by slag involved in the pouring process, so that the product is scrapped, the delivery time of the whole car and the time of selling the product are influenced, and huge losses are brought to a casting factory and a whole car manufacturer.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims at providing a low defect disappearance mould casting system for producing car stamping die, its characterized in that includes terrace die, sprue, filtration, ingate, the filtration is installed to the sprue downside, another section sprue is installed to the filtration downside, this sprue downside and ingate connection, the discharge gate terrace die bottom contact of ingate; the filtration comprises shell, filter screen, interface, shell internally mounted has the filter screen, the shell both sides are equipped with the interface, the interface top is equipped with the hang plate, ann's picture peg is installed to the hang plate upside.

The sprue gate is characterized in that the inner sides of two ends of the sprue are of inclined structures, an inserting groove is formed in each inclined structure, an inserting plate is inserted into the inserting groove, and a sprue gate is installed at the top end of the sprue gate.

The shell, the filter screen and the interface are of an integrated structure.

The filtering structure is made of ceramic materials.

And the inclined structures on the inner sides of the two ends of the sprue are matched with the inclined plates of the filtering structure interface.

The utility model has the advantages that: the utility model discloses a guarantee to produce the lost foam casting terrace die of low defect, special design uses the sprue as getting into the main canal, and the production technology of filter screen is used in the cooperation of ingate, produces the lost foam casting terrace die that has characteristics such as low defect, high performance. The utility model firstly eliminates the previous huge male die casting system and the previous huge runner system, and reduces the channels and paths for foreign matters to enter the male die, thereby reducing the occurrence of male die defects and greatly improving the qualification rate of male die products; on the other hand, the production efficiency of the lost foam casting male die is improved by simplifying a pouring system of the male die, the manufacturing period of the casting male die is shortened, the energy consumption and the data consumption required in the production process are greatly reduced, and the social and economic effects are good. The utility model discloses an inboard slope structure in sprue both ends and the hang plate cooperation on filtration's interface top avoid the molten iron to leak.

Detailed Description

As shown in the figure, it is right that the utility model discloses expound:

example 1

The utility model relates to a low defect disappearance mould casting system for producing car stamping die, its characterized in that includes terrace die, sprue, filtration, ingate, and the filtration is installed to the sprue downside, and another section sprue is installed to the filtration downside, and this sprue downside and ingate are connected, and the discharge gate terrace die bottom of ingate contacts; the filter structure comprises shell, filter screen, interface, and shell internally mounted has the filter screen, and the shell both sides are equipped with the interface, and the interface top is equipped with the hang plate, and ann's picture peg is installed to the hang plate upside. The inner sides of the two ends of the sprue are of inclined structures, an inserting groove is formed in each inclined structure, an inserting plate is inserted into the inserting groove, and a pouring gate is installed at the top end of the sprue. The filter structure comprises shell, filter screen, interface, and shell internally mounted has the filter screen, and the shell both sides are equipped with the interface, and the interface top is equipped with the hang plate. The shell, the filter screen and the interface are of an integrated structure.

Example 2

When the automobile stamping die is cast, firstly, the male die is fixed on a molding platform of the sand box, then sand is buried, then the sand box is overturned, the ingate and the filtering structure are installed at the bottom position of the male die, after the sand is buried, the pouring system is fixed at a fixed position in the sand box, the male die is prevented from displacing in the processes of moving, casting and the like, and the system is damaged. The filtering structure can well reduce the channel and the path of foreign matters entering the male die, thereby reducing the defects of the male die and greatly improving the qualification rate of male die products.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
