Description

Trimming mold with automatic product ejection function "

The present invention relates to a trimming mold, and more particularly, to a trimming mold having a function of taking out a product when the process is completed while performing a punching process and a burr removing process.

A trimming mold used in the process of processing a steel product using a forging process is a process for processing a hole in a molded product. In general, a trimming mold uses an upper mold and a lower mold in which an upper die and a lower die are respectively formed To fix the product, to machine the hole with a punch, or to remove the burr formed during the forging process.

After the precise manufacturing process, the product is fixed to the mold so that the punch hole that determines the punching position of the workpiece is matched, and the punch is pressed down through the press to process the hole in the product.

Prior art related to such a trimming mold includes Application Nos. 10-2006-0085000, 10-1996-0028166, 10-2008-0137684 filed in the Korean Intellectual Property Office.

However, the conventional trimming molds have problems in that they are combined in a state in which the product is inserted into the punch after the trimming process, or that it is difficult to separate the mold from the product due to the pressure of the trimming process.

It is an object of the present invention to provide a trimming mold having an automatic product take-out function according to the present invention which simultaneously removes burrs in the trimming process, and makes it easy to take out products after trimming.

A trimming mold having an automatic product take-out function according to the present invention includes an upper work table connected to a press device, a plurality of upper cylinder parts installed in a downward direction of the upper work table, An upper die fixed to the upper work table and formed on an outer side of the upper die to guide movement of the upper die; and an upper die fixed to the upper work table, A lower work table provided below the upper work table, a plurality of lower cylinder portions fixed to the upper side of the lower work table, a lower mold installed at an upper end of the lower cylinder portion and moved up and down, And a lower die coupled to the inside of the lower mold and fixed to the lower work table .

The upper mold removes a burr formed at an edge of the product placed on the lower die.

Further, the upper cylinder portion uses a nitrogen cylinder, and the lower cylinder portion uses an air cylinder.

The trimming mold having the automatic product takeout function according to the present invention has an advantage that the product can be conveniently taken out after the trimming process through the upper cylinder portion and the lower cylinder portion which are respectively provided in the upper mold and the lower mold.

1 is a cross-sectional view showing a trimming mold having an automatic product take-out function according to a preferred embodiment of the present invention.
2 to 7 are sectional views showing the operation of a trimming mold having an automatic product take-out function according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a sectional view showing a trimming mold having an automatic product take-out function according to a preferred embodiment of the present invention.

The trimming mold having the automatic product takeout function according to the present invention includes an upper work table 100, an upper cylinder 110, an upper mold 120, a punch 130, an upper die 140, a lower work table 200, A cylinder 210, a lower mold 220, and a lower die 230.

The upper work bench 100 is connected to the press apparatus and is moved up and down and is located on the upper side of the lower work bench 200 where the upper cylinder unit 110 and the upper mold 120 are fixed.

A plurality of upper cylinder units 110 are installed on the upper work bench 100 and upper dies 140 are installed on the lower end of the upper cylinder unit 110 and are moved up and down.

Here, it is preferable that the upper cylinder part 110 uses a nitrogen cylinder.

An upper mold 120 is formed on the outer side of the upper die 140 to guide movement of the upper die 140. The punch 130 is fixed to the upper work bench 100, And the upper die 140 through the through-hole.

That is, even if the upper die 140 is vertically moved by the upper cylinder 110, the punch 130 remains fixed to the upper work table 100, and as shown in FIG. 1, the punch 130 ) May be installed in a plurality of units depending on the product to be processed.

Next, the lower work bench 200 is installed below the upper work bench 100, and a plurality of lower cylinder parts 210 are installed on the lower work bench 200.

A lower die 220 is installed at an upper end of the lower cylinder 210 and is moved up and down. A lower die 230 is coupled to the lower mold 220, The die 230 is coupled with the upper die 140 to form the shape of the product.

Here, it is preferable that the lower cylinder 210 uses an air cylinder.

Here, the inner end of the upper mold 120 is coupled to remove the burr formed at the edge of the product placed on the lower die 230.

For a more detailed description, an operation procedure of a trimming mold having an automatic product take-out function according to the present invention will be described.

2 to 7 are sectional views showing a trimming mold having an automatic product take-out function according to a preferred embodiment of the present invention.

2, the lower mold 220 is moved vertically downward by the lower cylinder 210, and the lower die 230 for supporting the product in the trimming process after the movement is projected .

Here, a plurality of guide pins for supporting the product may be provided.

Next, as shown in FIG. 3, the worker places the product D to be trimmed on the lower die 230.

When the product is lifted, the operator operates the press as shown in FIG. 4 to move the entire upper work bench 100 in the vertical downward direction.

5, the upper die is contacted with the product D placed on the lower die 230, and the upper die part 110 is compressed while the upper die part 140 is compressed Is pushed upward, and the punch 130 fixed to the upper work table 100 processes the hole in the product.

At this time, the upper mold 120 removes the burr generated in the forging process of the product placed on the lower die 230.

When the trimming process is completed, the upper work bench 100 is vertically moved upward as shown in FIG. 6, and the compressed upper cylinder 110 pushes the upper die 140 downward .

Therefore, even if the product is coupled to the punch 130 in the trimming process, the product can be taken out by the upper cylinder 110.

Finally, as shown in FIG. 7, the lower cylinder portion 210 pushes the lower mold 220 upward to take out the bur.

As described above, the present invention provides a trimming mold having an automatic product takeout function as a main technical idea, and since the above-described embodiment is only one embodiment with reference to the drawings, It should be determined by the range.
