Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a direction-changing material cutting structure mainly used in a stamping die for a product which is complicated and difficult to cut out. Background Art

[0002] In stamping die technology, the upper size of the product is larger than the lower size. When the punch is punching from top to bottom, the punch will collide with the upper part of the product, causing the product to deform and unable to separate the product. Usually, the product is turned over with the small part facing up and the large part facing down, thus avoiding the punch contacting the upper part of the product and preventing product deformation.

[0003] We now use new technology and a new mold structure to separate products, thereby not changing the characteristics of the original products, and use directional motion punching to achieve product cutting. Utility Model Content

The cutting block is provided with a cutting groove for the cutter to move when the cutter floats, an oblique floating structure arranged in the lower mold is provided at both ends of the cutter, and a push rod for lifting the oblique floating block is provided in the lower mold below the oblique floating structure. The cutter is pushed downward by the punch and guided by the oblique floating structure to change direction for cutting materials. The push rod lifts the oblique floating block to drive the cutter upward, so that the material does not interfere with the position of the cutter when it moves forward.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: the punch is driven by the upper die, so that the punch pushes the cutter to move, and under the action of the oblique floating structure and the push rod, the cutter can move left and right and up and down to cut off the product. Through the power of the punch and the oblique floating structure, the cutter changes the cutting direction, avoids colliding with the upper part of the product during the downward cutting process, effectively enters the product cutting position to realize the separation of cutting and product, and can effectively realize the cutting of the product.

In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0014] See also Figures 1 to 5 The present embodiment provides a direction-changing cutting structure in a mold, which includes a punch 1 driven by an upper mold, a floating cutter 2 arranged in a lower mold and pushed by the punch 1 to gradually change direction and approach the material, and a cutting block 3 arranged in the lower mold and cooperating with the cutter 2 to cut materials. The cutting block 3 is provided with a cutting groove 30 for the cutter 2 to move when the cutter 2 floats, and both ends of the cutter 2 are provided with an oblique floating structure 4 arranged in the lower mold. A push rod 5 for lifting the oblique floating block 41 is provided in the lower mold below the oblique floating structure 4. By arranging the punch 1, the cutter 2, the oblique floating structure 4 and the push rod 5 to cooperate with each other and transmit the up, down, left and right movements to each other to realize the punching and separation of the product, and the cutting block 3 is provided, so that the cutter 2 can effectively separate the product from the residual material. At the same time, the push rod 5 is provided to lift the cutter 2 to avoid interference with the position of the cutter 2 when the material moves forward, so that the product can pass from under the cutter 2 and be discharged smoothly.

[0015] In this embodiment, the oblique floating structure 4 includes a fixed block 40, an oblique floating block 41 and a connecting block 42. The fixed block 40 is arranged in the lower mold, and the fixed block 40 is provided with an oblique groove. The oblique floating block 41 is slidably installed in the oblique groove. The oblique floating block 41 is provided with a slot. The connecting block 42 is installed in the slot, and one end of the connecting block 42 extends to the outside of the slot. The connecting block 42 extending to the outside of the slot is provided with a connecting port 420 connected to the cutter 2. The two ends of the cutter 2 are connected to the connecting blocks 42 on both sides, so that the punch 1 can push the cutter 2, and the oblique floating block 41 slides along the oblique groove, so that the cutter 2 changes direction and gradually approaches the product cutting position. When the cutter 2 cuts off the product and the residual material, the cutter 2 is inserted into the cutting groove 30, and the oblique floating block 41 is pushed by the push rod 5. The oblique floating block 41 drives the cutter 2 to move upward, providing a movable gap for the product, so that the product passes from under the cutter 2.

[0016] In this embodiment, the cutter 2 includes a downward pressing connection end 20 which is horizontally arranged and connected to the connecting blocks 42 on both sides, and a cutting protrusion 21 which is arranged in the middle section of the downward pressing connection end 20 and along the thickness direction of the downward pressing connection end 20. Stop blocks 22 are arranged on both sides of the downward pressing connection end 20 away from the cutting protrusion 21. When the two ends of the downward pressing connection end 20 are inserted into the connecting port 420, the end faces of the stop blocks 22 contact the end faces of the oblique floating blocks 41. By setting the stop blocks 22, the downward pressing connection end 20 can be prevented from moving left and right due to the extrusion force when the cutting protrusion 21 is cutting, and the cutting protrusion 21 can be prevented from colliding with the cutting block 3, thereby playing a positioning role and ensuring the safety during cutting.

[0017] Preferably, in order to facilitate installation and disassembly and maintenance, a fool-proof groove 401 is provided on one side wall of the fixed block 40 of the inclined groove, and a slip-off flange 410 that slides in cooperation with the fool-proof groove 401 is provided on the side of the inclined floating block 41.

[0018] To sum up, in the utility model, the punch 1 is driven by the upper die, so that the punch 1 pushes the cutter 2 to move, and under the action of the oblique floating structure 4 and the push rod 5, the cutter 2 can move left and right and up and down to cut the product. Through the power of the punch 1, in conjunction with the oblique floating structure 4, the cutter 2 changes the cutting direction, avoids colliding with the upper part of the product during the downward cutting process, effectively enters the product cutting position to realize the separation of the cutting product, and can effectively realize the cutting of the product.
