Fig. 1 is an overall schematic view of the present invention.
Fig. 2 is a schematic view of a second thimble.
In the above drawings, an upper die body 1, a lower die body 2, a first ejector pin 3, a die hole 4, a linear blade 5, a second ejector pin 6, a workpiece to be machined 7, a square groove 8 and a second spring 10.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1 and fig. 2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
Example (b): as shown in fig. 1 and 2, a special die for manufacturing a slotted screw comprises an upper die body 1 and a lower die body 2, wherein a first thimble 3 which is vertically downward is arranged in the middle of the upper die body 1; vertical nib 4 has been seted up at the middle part of lower mould body 2, is provided with the ascending word blade of cutting edge 5 in the nib 4, and the below of a word blade 5 is provided with vertical ascending second thimble 6, and second thimble 6 movable from top to bottom sets up in nib 4, and square groove 8 has been seted up to the upper end of second thimble 6, and a word blade 5 sets up directly over square groove 8, and the degree of depth of square groove 8 is greater than the height of a word blade 5. When the mold is opened, the lower end of the second thimble 6 protrudes out of the lower mold body 2; when the mould is closed, the upper end of the second thimble 6 is higher than the straight blade 5.
The principle is as follows: as shown in fig. 1, firstly, a to-be-machined part 7 is put into a die hole 4 from above a lower die body 2, then the upper die body 1 drives a first ejector pin 3 to move downwards, the first ejector pin 3 enters the die hole 4, under the extrusion action of the first ejector pin 3, the to-be-machined part 7 is pressed into a linear blade 5 in the lower die body 2, and after a linear groove at the tail part of a screw is formed, the to-be-machined part is ejected out through a second ejector pin 6, and machining is completed.
