Refer to fig. 1-5.

The utility model provides a material jumping prevention structure of a die, which comprises an upper die base 1, a slotting tool clamping plate 2, a stripper plate 3, a female die 4, a lower backing plate 5 and a lower die base 6 which are sequentially arranged from top to bottom, wherein the slotting tool clamping plate 2 is fixedly connected at the bottom of the upper die base 1, a first slotting tool 7 and a second slotting tool 8 are fixedly connected on the slotting tool clamping plate 2, the lower backing plate 5 is fixedly connected at the top of the lower die base 6, the female die 4 is fixedly connected at the top of the lower backing plate 5, the stripper plate 3 is fixedly connected at the top of the female die 4, a first side punching head 9 and a second side punching head 10 which are oppositely arranged are arranged on the stripper plate 3 in a sliding way, the first side punching head 9 and the second side punching head 10 both comprise a sliding table 90 and a tool bit 91 which is arranged at one side of the sliding table 90 in an extending way, a sliding inclined plane 900 is arranged on one side of the sliding table 90, an inclined plane knife edge 910 which is obliquely arranged is arranged on the inner side of the knife head 91, the outer side surfaces of the bottom ends of the first slotting tool 7 and the second slotting tool 8 are respectively provided with a slotting tool inclined plane 80 which is matched with the sliding inclined plane 900, the top of the female die 4 is provided with a processing groove 40 which is used for positioning the section bar, waste holes 41 are formed in the female die 4 and are positioned on two sides of the processing groove 40 in a penetrating mode, a knife head side punching groove 42 which is communicated with the processing groove 40 and the waste holes 41 is formed in the top of the female die 4 in a penetrating mode, and when the section bar is subjected to side punching through the first side punching head 9 and the second side punching head 10, the inclined plane knife edge 910 moves along the knife head side punching groove 42 and pushes waste materials punched from the section bar into the waste holes 41.

The specific use principle is as follows: after the section is placed on the processing groove 40, the upper die holder 1 is pushed downwards to move towards the lower die holder 6 side to close the die, the slotting tool inclined planes 80 of the first slotting tool 7 and the second slotting tool 8 respectively approach to the sliding inclined planes 900 on the first side punch 9 and the second side punch 10, when the slotting tool inclined planes 80 abut against the sliding inclined planes 900, the slotting tool inclined planes 80 move along the sliding inclined planes 900 and cause the first side punch 9 and the second side punch 10 to move outwards, the inclined plane knife edge 910 moves along the knife edge side punching groove 42 and punches the section, and the waste materials punched out of the section are pushed into the waste material hole 41 by the inclined plane knife edge 910 and are discharged. Because the inclined plane knife edge 910 which is arranged obliquely punches the section bar, the waste material is clamped between the inclined plane knife edge 910 and the female die 4 when the waste material is subjected to side punching and then is pushed into the waste material hole 41, and the problems that the waste material is stuck to a punch head and the waste material is jumped can be effectively avoided after the side punching.

Based on the above embodiment, both sides of the top of the lower padding plate 5 are fixedly connected with the supporting blocks 11, the material removing back plate 12 is fixedly connected between the top ends of the two supporting blocks 11, and the material removing plate 3 is fixedly connected to the bottom of the material removing back plate 12. When the mold clamping is carried out, when the slotting tool clamping plate 2 abuts against the stripping back plate 12, the slotting tool clamping plate 2 stops moving, the mold clamping is completed, and the limiting effect is achieved.

Based on the above embodiment, the bottom of the stripper plate 3 is provided with the punch movable groove 30, the first side punch 9 and the second side punch 10 are movably arranged on the punch movable groove 30, one end of each of the first side punch 9 and the second side punch 10 is provided with the return spring 13 abutted against the end wall of the punch movable groove 30, and one end of each of the first side punch 9 and the second side punch 10 is abutted against the elastic force of the return spring 13. Initially, one end of the first side punching head 9 and one end of the second side punching head 10 are abutted under the elastic force of the return spring 13; when the die is closed, the slotting tool inclined plane 80 moves along the sliding inclined plane 900, the first side punching punch 9 and the second side punching punch 10 move outwards and compress the return spring 13 to perform side punching on the section bar; when the die is opened, the first side punching head 9 and the second side punching head 10 are reset under the elastic force of the reset spring 13.

The above embodiments are only described as preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
