Example 1

A core pulling structure with a straight ejection and elastic mechanism comprises a movable die 1, wherein a sliding groove is formed in the movable die 1, a straight ejection block 4 slides in the sliding groove, a sliding cavity 2 is formed in the straight ejection block 4, a drawing needle 3 slides in the sliding cavity 2, and the drawing needle 3 extends out of the sliding cavity 2 to a buckling position 6 of a product 5;

an elastic device is fixed on the drawing needle 3; the other end of the elastic device is fixed in the sliding cavity 2, and a limiting mechanism for limiting the sliding stroke of the drawing needle 3 is further fixed in the sliding cavity 2.

The sliding cavity 2 and the straight jacking block 4 are obliquely arranged on one side of the spring 8. The sliding cavity 2 and the straight top block 4 are inclined obliquely upwards towards the ejection direction of the draw pin 3.

The end of the drawing pin 3 remote from the spring 8 is also arranged obliquely. The straight ejector block 4 moves upwards, and because the distance between the inclined end face of the straight ejector block 4 and the inclined end face of the sliding cavity 2 is gradually increased, the spring 8 works, the spring 8 applies elasticity to the drawing needle 3, and the drawing needle 3 pops out, so that the tripping action is completed.

The limiting mechanism comprises a limiting block 7, the limiting block 7 is fixed on one side of the sliding cavity 2 through a bolt, a flat position 10 is arranged on the pull needle 3, and the flat position 10 is matched with the limiting block 7 to limit the sliding stroke of the pull needle 3. When the drawing needle 3 moves towards one end far away from the spring 8 and moves for a certain distance, the flat position 10 on the drawing needle 3 props against the limiting block 7, so that the drawing needle 3 cannot move continuously under the action of the elasticity of the spring 8. If the extraction needle 3 extends out of the straight ejection block 4 too long, the extraction needle 3 can not be reset, and if the extraction needle 3 extends out of the straight ejection block 4 too short, the extraction needle 3 can not complete the tripping action.

The drawing needle 3 comprises a main body portion 12 and a core pulling portion 11 fixedly connected with the main body portion 12, a flat position 10 is arranged on the main body portion 12, the core pulling portion 11 is sleeved with a spring 8, one end of the spring 8 abuts against the main body portion 12, and the other end of the spring abuts against the inner wall of the sliding cavity 2.

The device is characterized by further comprising a push rod 9 for driving the straight push block 4 to move, the push rod 9 is fixedly connected with the straight push block 4, a guide groove 13 is formed in the movable die 1, and the push rod 9 is arranged in the guide groove 13 in a sliding mode. The ejector rod 9 drives the straight ejector block 4 to move upwards or downwards in the guide groove 13, and the structure of the guide groove 13 is adopted, so that the movement stability of the ejector rod 9 is improved.

The drawing needle 3 is made of SKD 61.

The working principle is as follows: the ejector rod 9 moves in the guide groove 13 to drive the straight ejector block 4 to move upwards, the straight ejector block 4 moves upwards, the distance from one end, far away from the spring 8, of the straight ejector block 4 to one end, far away from the spring 8, of the sliding cavity 2 is larger and larger, and at the moment, the drawing needle 3 moves towards the direction far away from the spring 8 under the action of the spring 8. When the withdrawing needle 3 moves towards one end far away from the spring 8 and moves for a certain distance, the flat position 10 on the withdrawing needle 3 props against the limiting block 7, so that the withdrawing needle 3 cannot move continuously under the action of the elastic force of the spring 8, and the core-pulling part 11 of the withdrawing needle 3 finishes tripping action at the moment.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
