Description

[0001] Die casting of finishing equipment [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post-processing apparatus for a die casting casting, and more particularly, to a post-processing apparatus for a die casting casting, in which die casting casting is rapidly cooled The present invention relates to a post-processing apparatus for a casting, and further, an improved invention of the applicant's pre-registered patent No. 10-0845768.

In general, die casting is also referred to as die casting, and molten metal (such as aluminum or magnesium) is injected into a steel mold die that is precisely machined to fully conform to the required cast shape The die cast casting (hereinafter referred to as "casting") is a precision casting method for obtaining the same casting as a mold

When a casting is produced by such die casting, a runner is integrally attached to the casting, and therefore, a work process for removing the runner by using a press device is inevitably required.

Here, when the runner is removed, the runner is not completely removed or the shape of the casting may be deformed when the pressing process is performed in a state where the casting is not completely solidified. Therefore, the casting is generally carried in a cooling water tank, So that a runner integrally attached to the casting is removed.

However, in the conventional cooling method using the cooling water, since the casting is carried by cooling the casting in the cooling water, the casting having a complicated structure has a problem in that the water penetrated into the casting is not discharged and kept inside .

Particularly, when moisture is present in the casting, the casting may be deformed or rusted and may be damaged. Therefore, there is a serious need for a method capable of solving such problems.

Therefore, in order to solve the above problems, the applicant of the present application proposed an air cooling type casting cooling apparatus for rapidly cooling a plurality of castings at one time without damaging the casting by using a blower of a casting mold as a patent registration No. 10-0845768 There is a bar.

The present invention relates to a casting machine, and more particularly, to a casting machine having a casting machine and a casting machine. The casting machine includes a main body frame, a rotation driving part provided at one side of the frame, A casting seating part on which the casting is placed on the rotary part, and a blower installed on one side of the frame and supplying cool air to the casting seating part.

Therefore, the casting seating portion of the rotating portion is rotated in an infinite track by the power of the rotary driving portion provided on the frame. The molded casting is carried in and out of the casting seating portion by a separate robot, Cooled by the wind supplied from the blower.

The above-mentioned prior art patent has the effect that is required in the prior art patent because the casting to be molded is placed on the casting seating part to cool it as a blower, but this has the effect of having only the cooling function as described above, .

On the other hand, the primary molded casting requires not only a process of removing the runner but also eliminates the burr and the corner generated on the surface of the casting, or the hole of a bolt hole or the like at a specific position It is inevitably required to perform a post-processing operation such as drilling.

For example, burrs generated in molding a casting are post-processed as a grinding method using a grinding stone, a brush, sandpaper, water or the like, or post-processed by drilling a hole in the surface of a casting formed by a drilling process. A variety of things can be done depending on the characteristics.

In the post-processing operation, the post-processing operation is performed separately from the runner removing operation, that is, after the cooling operation and the runner removing operation are sequentially performed, a separate post-operation operation is performed. There is a problem that the space is not good because the installation space of the post-processing machine is required.

It is an object of the present invention to provide a cooling function for cooling a casting produced by a die casting, and also to provide a cooling function for removing unnecessary burrs generated on the surface of the casting, And a post-processing function of the die casting casting.

Another object of the present invention is to provide a die casting casting which can simultaneously perform two different working processes as a single operation line by simultaneously forming a cooling device for cooling the casting in one device and a post- And to provide a post-processing apparatus.

Another object of the present invention is to provide a post-processing apparatus which is selected according to the characteristics of a product, such as a brush processing means using a brush tool, and a drilling means for drilling a hole of a fastening hole or the like, So as to improve ease of use and compatibility of the machine, as well as an improvement in workability.

In order to accomplish the above object, the present invention provides a method of continuously circulating a molded casting by using a mechanical device and cooling the molded casting as a blower, Thereby enabling post-processing to be performed.

The present invention relates to a casting machine comprising a frame constituting an entire body, a rotating part mounted on the frame and running in an infinite track manner, a casting seating part for placing a casting while a plurality of the casting parts are installed at a predetermined interval, A cooling part installed on one side of the frame for blowing wind, a casting part mounted on the casting seating part while being installed on the frame, And a cooling unit including a fixing unit for fixing the cooling unit to the cooling unit.

In addition, a brush processing means for removing or polishing burrs on the surface of the casting on the frame of the cooling device and a drilling means for drilling a hole in the surface of the casting are provided either singly or in combination so that the casting formed by die casting So that the cooling device and the post-processing device can be simultaneously performed in one apparatus.

The present invention can rapidly cool castings formed by die casting, and can simultaneously perform post-processing required for casting in a cooling process.

In other words, according to the present invention, a cooling device of a casting and a finishing device of a casting are simultaneously provided in one device, and these operations are performed organically so that the working time is shortened and the working efficiency is remarkably improved.

The present invention is configured such that a plurality of castings are circulated in an infinite track manner in a narrow space and cooled by using a separate blower so that the casting can be installed even in a narrow space of the room, The casting mold can be cooled.

In addition, it is also possible to perform post-processing of the casting necessary for the process of transferring the casting to the above-mentioned equipment, for example, brushing for removing or polishing the burr generated in the molded casting, drilling for drilling various holes such as a bolt hole on the casting It is possible to simultaneously perform post-processing including the above-mentioned post-processing.
