Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Fig. 4, a kind of manufacturing mold that is used for cup-rod type cold extruded part is installed above a press table 1 with top cylinder 2 as a whole, including:

a fixed part, the fixed part includes a lower template 3 arranged above the press table 1,

A large mold frame 4, a die 5, and a pressing plate 6 are sequentially arranged above the lower template 3; a die cavity 7 is formed between the die 5 and the large die frame 4; a mold core 8 is also vertically arranged , the upper end of the mold core 8 is connected to the press plate 6, and the lower end is placed inside the large mold frame 4;

The moving part includes an upper slider A10, the upper mold 12 and the upper slider B11 are sequentially connected under the upper slider A10, and a punch 13 is installed under the upper mold 12, and the lower end of the punch 13 passes through the The above slider B11.

A fixing sleeve 14 is provided below the upper template 12, and the punch 13 is fixed below the upper template 12 by the fixing sleeve 14; the lower end of the punch 13 passes through the exposed part of the upper slider B11 A punch cover 15 is provided, and the punch cover 15 and the punch 13 can slide up and down relative to each other.

A support plate 16 is arranged horizontally in the middle of the large mold frame 4, and a ejector pin 9 perpendicular to the support plate 16 and capable of upward ejection is provided through the support plate 16, and the die cavity 7 is above the ejector pin 9. , when the jack cylinder 2 is pushed out upwards, it can drive the ejector rod 9 to move upwards.

The specific implementation is divided into the following steps:

Step 1: The upper slider A10 and the upper slider B11 go down as a whole;

Step 2: After the punch 13 touches the blank in the die cavity 7, the upper slider A10 and the upper slider B11 still move downward as a whole;

Step 3: After the punch 13 presses the blank to the predetermined position, the upper slider B11 rises to the designated position;

Step 4: After the upper slider B11 rises to the position, the upper slider A10 and the upper slider B11 go down as a whole, and the punch 13 presses the blank to press the column hole. At this time, only the punch 13 presses the blank, and the punch set 15 does not exert pressure on the billet;

Step 5: After the column hole pressing is completed, the upper slider A10 and the upper slider B11 go up;

Step 6: After the upper slider A10 and the upper slider B11 move up to the position as a whole, the upper slider B11 moves down to the original position, and the ejector cylinder 2 moves upward through the ejector pin 9 to eject the workpiece in the die cavity 7 .

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
