Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. A blanking die is a type of mold that separates sheet metal along a closed contour line, with the material within the contour line being used as a blanking part. This process is called blanking, and it completes the blanking process.

[0003] However, it still has the following drawbacks in practical use:

[0004] When using existing blanking dies, the sheet metal needs to be placed on the upper part of the lower die. Usually, the upper die moves downward to close the die, thereby separating the sheet metal along the contour line. When the sheet metal is placed crookedly on the upper part of the lower die, the sheet metal cannot be fully separated along the contour line, resulting in waste of sheet metal and increased production costs.

[0005] Therefore, a new mold is proposed to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a mold to solve the problem mentioned in the background art that when using existing blanking molds, the sheet material needs to be placed on the upper end of the lower mold, and the upper mold usually moves downward to close the mold, thereby separating the sheet material along the contour line. When the sheet material is placed crookedly on the upper end of the lower mold, the sheet material cannot be fully separated along the contour line, resulting in waste of sheet material and increased production costs.

[0008] Technical solution

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a mold, comprising:

[0011] Mold assembly, including the lower mold;

[0012] Positioning assembly; the positioning assembly includes a turntable fixedly connected to the outer side of the upper end of the lower mold, a rotating shaft fixedly connected to the inner side of the turntable, a limiting tube fixedly connected to the outer surface of the center of the rotating shaft, a sleeve threadedly connected to the outer surface of the rotating shaft, a positioning plate fixedly connected to the upper end of the outer side of the sleeve, and a rotating cylinder rotatably connected to the center of the upper end of the positioning plate.

[0013] The detachable component is fixedly connected to the upper part of the lower mold.

[0014] Furthermore, the mold assembly also includes a pressure column fixedly connected to the upper end of the lower mold and an upper mold placed above the lower mold.

[0015] Furthermore, the outer surface of the rotating shaft is provided with a threaded structure, and the two sets of sleeves have opposite threaded structures inside.

[0016] Furthermore, the positioning plate and the rotating cylinder are located on both sides of the upper end of the lower mold, and the positioning plate has an L-shaped structure.

[0017] Furthermore, the separation assembly includes a first fixing plate fixedly connected to the outer side of the lower mold, a second fixing plate fixedly connected to the outer side of the first fixing plate, a support rod fixedly connected to the inner side of the second fixing plate, a first slide rail fixedly connected to the upper end of the support rod, a guide rail fixedly connected to the upper end of the lower mold, a second slide rail fixedly connected to the upper end of the guide rail, a first slider slidably connected to the upper end of the guide rail, and a second slider slidably connected to the side of the guide rail.

[0020] Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] I. This utility model, by setting a positioning component, fixes both sides of the plate with positioning blocks and rotating cylinders at both ends of the lower mold, ensuring that the plate will not be tilted when placed. At the same time, the rotation of the turntable drives the rotating shaft to rotate, and the rotating shaft drives the sleeves at both ends to move through the threaded structure, thereby positioning plates of different widths.

[0023] Second, based on the first beneficial effect, by setting up a separation component, when the waste sheet material is moved outward after the mold is closed, the processed parts and waste sheet material can slide outward from the upper end of the first slide and the second slide respectively. Since the first slide and the second slide are intersected, the parts and waste sheet material on the first slide are separated, eliminating the need for manual sorting.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] Example 1

[0036] Please see Figure 1-3 As shown, this embodiment is a mold, including:

[0037] Mold assembly 1 includes a lower mold 11;

[0038] Positioning assembly 2; Positioning assembly 2 includes a turntable 21 fixedly connected to the outer side of the upper end of the lower mold 11, a rotating shaft 22 fixedly connected to the inner side of the turntable 21, a limiting tube 23 fixedly connected to the outer surface of the center of the rotating shaft 22, a sleeve 24 threadedly connected to the outer surface of the rotating shaft 22, a positioning plate 25 fixedly connected to the upper end of the outer side of the sleeve 24, and a rotating cylinder 26 rotatably connected to the center of the upper end of the positioning plate 25;

[0039] The turntable 21 is used for hand-held rotation. The rotating shaft 22 rotates under the drive of the turntable 21. The limiting tube 23 can limit the minimum distance between the sleeves 24. The sleeves 24 are used to drive the positioning plate 25 to move. The positioning plate 25 is used to limit the two sides of the plate. When the plate moves, it can drive the rotating drum 26 to rotate.

[0040] The mold assembly 1 also includes a pressure column 12 fixedly connected to the upper end of the lower mold 11 and an upper mold 13 placed above the lower mold 11;

[0041] The pressure column 12 is used to separate the sheet metal, and the upper mold 13 and the lower mold 11 can be closed.

[0042] The outer surface of the rotating shaft 22 is provided with a threaded structure, and the two sets of sleeves 24 have opposite threaded structures inside;

[0043] When the rotating shaft 22 rotates, it drives the two sets of sleeves 24 to move towards each other or in opposite directions through the thread mechanism;

[0044] The positioning plate 25 and the rotating cylinder 26 are located on both sides of the upper end of the lower mold 11, and the positioning plate 25 has an L-shaped structure;

[0045] The lower end of the positioning plate 25 is used to support the sheet material, and the side of the positioning plate 25 is used to limit the position of the sheet material.

[0046] Working principle: When the sheet metal needs to be processed, the sheet metal is placed on the upper end of the lower mold 11, and a rotational force is applied to the turntable 21 to make the turntable 21 rotate. The rotation of the turntable 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the sleeve 24 to move through the threaded structure. When the sleeve 24 moves, it drives the positioning plate 25 and the rotating cylinder 26 to move. When the positioning plate 25 moves to the side and contacts the side of the sheet metal, the outer surface of the rotating cylinder 26 is tangent to the sheet metal. The rotating cylinder 26 and the positioning plate 25 can then position the sheet metal and drive the sheet metal to move through the rotation of the rotating cylinder 26 for placing or removing the sheet metal.

[0047] Example 2

[0048] Please see Figure 3 As shown, this embodiment, based on embodiment 1 above, further includes:

[0049] Separation component 3 is fixedly connected to the upper end of the lower mold 11;

[0050] The separation assembly 3 includes a first fixing plate 31 fixedly connected to the outer side of the lower mold 11, a second fixing plate 32 fixedly connected to the outer side of the first fixing plate 31, a support rod 33 fixedly connected to the inner side of the second fixing plate 32, a first slide rail 34 fixedly connected to the upper end of the support rod 33, a guide rail 35 fixedly connected to the upper end of the lower mold 11, a second slide rail 36 fixedly connected to the upper end of the guide rail 35, a first slider 37 slidably connected to the upper end of the guide rail 35, and a second slider 38 slidably connected to the side of the guide rail 35.

[0051] The second fixing plate 32 is fixed to the outer side of the first fixing plate 31 by bolts. The second fixing plate 32 is used to support the support rod 33. The support rod 33 is used to support the first slide rail 34. The first slide rail 34 is used to slide the part. The guide rail 35 is used to support the second slide rail 36. The second slide rail 36 is used to slide the sheet metal. The first slider 37 and the second slider 38 are used to fix the second slide rail 36 and the guide rail 35.

[0052] The first slider 37 is fixedly connected to both sides of the second slide rail 36, and the second slider 38 is fixedly connected to the bottom of the second slide rail 36, with the first slide rail 34 and the second slide rail 36 intersecting each other;

[0053] The first slider 37 fixes both sides of the second slide rail 36, and the second slider 38 fixes the lower end of the second slide rail 36;

[0054] The first slide rail 34 is collinear with the pressure column 12, and the second slide rail 36 is located on both sides of the pressure column 12;

[0055] The part slides from the top of the pressure column 12 through the first slide rail 34, and the material slides through the second slide rail 36.

[0056] Working principle: When the upper mold 13 closes downwards, the sheet metal is separated and pulled outwards. At this time, the waste sheet metal slides through the second slide rail 36. The part moves from the upper end of the pressure column 12 to the upper end of the first slide rail 34 and slides under the action of the waste sheet metal. Since the part and the sheet metal are separated by the pressure column 12, the part moves downwards from the outer end of the first slide rail 34, and the waste sheet metal moves outwards from the second slide rail 36, thus separating the part and the waste sheet metal.
