Description

Disposable barb bending mould

Technical field

[0001] The utility model relates to the field of metal mold structures, and more particularly to a disposable barb bending forming mold.

Background technique

[0002] With the advancement of science and technology, the various tools and products used in our daily production and life are closely related to the mold. In the production process of some products, the barb bending process needs to be performed on the product. The existing barb bending process is divided into two parts: first forming L-curve, then forming barb bending, and using this method to produce 吋 requires two sets of dies , two stamping personnel and two presses, the cost of mold and labor and the use of stamping equipment are higher.

technical problem

The technical problem to be solved by the present invention is to provide a one-time barb bending forming mold for the above-mentioned drawbacks of the prior art.

Problem solution

Technical solution

[0004] A disposable barb bending forming mold is characterized in that: a clamping plate fixing block, a lower mold sliding block and a lower mold pushing block; wherein the clamping plate fixing block is provided with an upper mold sliding block; The upper die block includes an upper half portion and a lower half portion, the upper half portion has a blind hole laterally, and the blind hole is provided with a return spring fixed at one end of the blind hole; the lower half portion One end of the blind hole is provided with a protrusion for bending the product to be processed, and the other end is provided with a slope corresponding to the bending direction of the product to be processed; the lower mold block is located on the upper mold slide a lower side of the block is adjacent to the convex side, and is provided with a lobe that is in close contact with the curved back surface of the product to be processed; the lower mold pushing block is located below the inclined surface, and is provided to cooperate with the inclined surface The faceted.

[0005] The disposable barb bending molding die of the present invention, wherein the upper die slider is fixedly connected to the clamping plate slider fixing block by a pressure plate.

[0006] The disposable barb bending molding die of the present invention, wherein the cutting surface and the lower die push block The top joint surface is curved.

[0007] The disposable barb bending molding die of the present invention, wherein the protrusions form a curved surface of the product.

[0008] The disposable barb bending forming mold of the present invention, wherein a surface connecting surface of the inclined surface and the upper mold slider is a curved surface.

Advantageous effects of the invention

Beneficial effect

[0009] When the mold is closed, the protrusion of the upper mold slider first contacts the product to be processed, and the product to be processed is shaped into an L curve. When the inclined surface of the upper mold slider contacts the cut surface of the lower mold push block, the upper mold slide will The direction of the cut surface is moved, and the curved shape is formed into a barb to achieve the purpose of one-time barb bending and molding, thereby reducing the use of the mold process and the punching equipment, reducing the labor cost, and the structure is simple, the space is small, and the production efficiency is improved. Brief description of the drawing

DRAWINGS

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, in which:

1 is a schematic view showing the implementation of a disposable barb bending molding die according to a preferred embodiment of the present invention;

2 is a schematic structural view of an upper mold slider according to a preferred embodiment of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION

[0013] The preferred embodiment of the present invention, the disposable barb bending molding die shown in Figure 1, see also Figure 2, including the cleat slider fixed block 1, the lower die block 3 and the lower die push block 4; The upper block slider 2 is provided with an upper die block 2; the upper die block 2 includes an upper half 21 and a lower half 22, the upper half 21 has a blind hole 211 laterally, and one end is provided in the blind hole 211 a return spring 6 fixed to the bottom of the blind hole 211; a lower half 22 of the blind hole 211 is provided with a protrusion 221 for bending the product to be processed 5 at the end of the blind hole 211, and the other end is provided with a bending direction of the product 5 to be processed. The lower mold slider 3 is located below the upper mold slider 2 near the protrusion 221 - side, and is provided with a lobe 31 which is in close contact with the curved surface of the product to be processed 5; the lower mold push block 4 is located at the inclined surface 222 Below, and provided with a cutting surface 41 matching the inclined surface 222; when the mold is closed, the protrusion 2 of the upper mold slider 2 21, the product 5 to be processed is first contacted, and the product 5 to be processed is formed into an L curve. When the inclined surface 222 of the upper die block 2 contacts the cut surface 41 of the lower die push block 4, the upper die block 2 moves in the direction of the cut surface 41. The L-curve is formed into a barb to achieve the purpose of one-time barb bending, which reduces the use of the mold process and the punching equipment, reduces the labor cost, and has the advantages of simple structure, small space occupation, and improved production efficiency.

As shown in FIG. 1 and FIG. 2, the upper mold block 2 is fixed to the clamp slider fixing block 1 by a press plate connection, thereby enhancing the strength of the mold itself and prolonging the service life of the mold.

[0015] As shown in FIG. 1, the top surface connecting surface of the cutting surface 41 and the lower mold pushing block 4 is a curved surface, and the upper mold slider 2 is in contact with the lower mold pushing block 4, thereby preventing the contact point from being too sharp. Mold damage.

As shown in FIG. 1 and FIG. 2, the protrusion 221 is curved to form a curved surface of the product, which prevents the contact point from being too sharp and causes the product 5 to be burred.

[0017] As shown in FIG. 1 and FIG. 2, the surface connection surface of the inclined surface 222 and the upper mold slider 2 is a curved surface, which prevents mold damage caused by the contact point being too sharp.

[0018] It is to be understood that those skilled in the art can devise modifications or variations in accordance with the above description, and all such modifications and changes are intended to be included within the scope of the appended claims.
