Description

Technical Field

[0001] This utility model belongs to the field of diamond tool tip production technology, and more specifically, it relates to a hot pressing mold and assembly tooling for forming diamond tool tips. Background Technology

[0002] In the production process of diamond cutting tools, a cutting tool blank is first made, then assembled with a hot pressing mold, and finally placed on a hot pressing sintering machine for hot pressing. Existing hot pressing molds include a mold frame and multiple extrusion groups, which are arranged horizontally within the mold frame. Each extrusion group includes an upper pressure head and a lower pressure head. The space between the upper and lower pressure heads is used to place the cutting tool blank, and the upper and lower pressure heads work together to extrude the cutting tool blank. A partition is also provided between adjacent extrusion groups to prevent adjacent diamond cutting tools from sticking together after hot pressing. Due to the limited space within the mold frame, the placement of partitions reduces the number of extrusion groups that can be placed, resulting in a smaller number of diamond cutting tools that can be hot-pressed in a single operation. Utility Model Content

[0003] The purpose of this utility model is to provide a hot pressing mold and assembly fixture for forming diamond cutter heads, which aims to solve the problem that the number of diamond cutter heads formed in one hot pressing is relatively small due to the limited space inside the mold frame and the placement of partitions.

[0004] In a first aspect, this utility model provides a hot pressing mold for forming diamond cutting tips, including a mold frame and an extrusion unit. The mold frame is horizontally arranged. The extrusion unit is disposed within the mold frame and includes a plurality of first extrusion groups and a plurality of second extrusion groups arranged in a crisscross pattern. Each of the first extrusion group and the second extrusion group includes a first pressure head and a second pressure head. A placement space for placing a cutting tip blank is formed between the first pressure head and the second pressure head. The first pressure head in the first extrusion group is located above the second pressure head, and the first pressure head in the second extrusion group is located below the second pressure head, so that any two adjacent placement spaces are spaced apart in the vertical direction.

[0005] Compared with the prior art, the solution shown in this application embodiment places the cutter blank in all placement spaces after the mold is assembled, and then the extrusion unit is hot-pressed to form the cutter blank into a cutter head. Since any two adjacent placement spaces are spaced apart in the vertical direction, the cutter heads formed without the use of partitions will not stick together. Therefore, it avoids the problem that the number of diamond cutter heads formed in one hot pressing is small due to the limited space in the mold frame and the use of partitions.

[0006] In conjunction with the first aspect, in one possible implementation, the hot press mold for forming diamond cutting tips further includes two first baffles, a first extrusion bolt, two second baffles, and a second extrusion bolt. The two first baffles are respectively located on both sides of the extrusion unit along a first horizontal direction. The screw of the first extrusion bolt penetrates the sidewall of the mold frame and is threadedly connected to the mold frame, and the first extrusion bolt abuts against one of the first baffles. The two second baffles are respectively located on both sides of the extrusion unit along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction. The screw of the second extrusion bolt penetrates the sidewall of the mold frame and is threadedly connected to the mold frame, and the second extrusion bolt abuts against one of the second baffles.

[0007] In conjunction with the first aspect, in one possible implementation, the first compression bolt is provided with at least two.

[0008] In conjunction with the first aspect, in one possible implementation, the second compression bolt is provided with at least two.

[0009] In conjunction with the first aspect, in one possible implementation, the two first baffles and the two second baffles form a receiving space, the upper and lower ends of which are located above and below the mold frame, respectively.

[0010] In conjunction with the first aspect, in one possible implementation, both the first pressure head and the second pressure head are partially inserted into the receiving space.

[0011] Secondly, this utility model embodiment also provides an assembly fixture for assembling the aforementioned hot press mold for forming diamond cutting heads, including a base plate. The base plate is horizontally arranged and used to support the mold frame, and the upper surface of the base plate is provided with a first receiving groove, the bottom wall of the first receiving groove being used to support the first baffle and the second baffle.

[0012] Compared with the prior art, the solution shown in this application places the mold frame on the base plate, and then places two first baffles and two second baffles on the bottom wall of the first receiving groove. In this way, the positional relationship between the first baffles and the second baffles and the mold frame in the vertical direction can be positioned, so that the upper end and the lower end of the receiving space are respectively located above and below the mold frame.

[0013] In conjunction with the second aspect, in one possible implementation, the bottom wall of the first receiving groove is provided with a second receiving groove, which is used to support the second pressure head in the first extrusion assembly.

[0014] In conjunction with the second aspect, in one possible implementation, the assembly fixture further includes a plurality of spacers. The spacers are arranged at intervals along the first horizontal direction, and the spacers are perpendicular to the first horizontal direction. The spacers are positioned between two adjacent spacers to allow the second pressure head in the first extrusion assembly to pass through.

[0015] In conjunction with the second aspect, in one possible implementation, the spacer plate and the two sidewalls of the second receiving groove located in the second horizontal direction have gaps. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0035] Please refer to the following: Figures 1 to 7 The hot pressing mold for forming diamond cutting tools provided by this utility model will now be described. The hot pressing mold for forming diamond cutting tools includes a mold frame 1 and an extrusion unit 2. The mold frame 1 is horizontally arranged. The extrusion unit 2 is disposed inside the mold frame 1 and includes a plurality of first extrusion groups 21 and a plurality of second extrusion groups 22 arranged in a crisscross pattern. Each of the first extrusion group 21 and the second extrusion group 22 includes a first pressure head 201 and a second pressure head 202. A placement space 2011 for placing a cutting tool blank 9 is formed between the first pressure head 201 and the second pressure head 202. The first pressure head 201 in the first extrusion group 21 is located above the second pressure head 202, and the first pressure head 201 in the second extrusion group 22 is located below the second pressure head 202, so that any two adjacent placement spaces 2011 are spaced apart in the vertical direction.

[0036] The hot pressing mold for forming diamond cutting heads provided by this utility model, compared with the prior art, places cutting head blanks 9 in all placement spaces 2011, and then hot presses the extrusion unit 2 to form the cutting head blanks 9 into cutting heads. Since any two adjacent placement spaces 2011 are spaced apart in the vertical direction, the cutting heads formed without the need for partitions will not stick together. Therefore, it avoids the problem that the limited space in the mold frame 1 leads to a smaller number of diamond cutting heads formed in one hot pressing due to the placement of partitions.

[0037] In existing technology, the bottom surface of the upper pressure head and the top surface of the lower pressure head are both arc-shaped surfaces, and the arc-shaped surfaces of the upper and lower pressure heads respectively match the two arc-shaped surfaces of the formed cutter head. In this embodiment, the surface of the first pressure head 201 facing the second pressure head 202 and the surface of the second pressure head 202 facing the first pressure head 201 are also arc-shaped surfaces, and the arc-shaped surfaces of the first pressure head 201 and the second pressure head 202 respectively match the two arc-shaped surfaces of the formed cutter head.

[0038] In some embodiments, see Figure 1 and Figure 8 The hot press mold for forming diamond cutting tools also includes two first baffles 3, a first extrusion bolt 4, two second baffles 5, and a second extrusion bolt 6. The two first baffles 3 are located on opposite sides of the extrusion unit 2 along a first horizontal direction. The screw of the first extrusion bolt 4 penetrates the side wall of the mold frame 1 and is threadedly connected to the mold frame 1, and the first extrusion bolt 4 abuts against one of the first baffles 3. The two second baffles 5 are located on opposite sides of the extrusion unit 2 along a second horizontal direction, which is perpendicular to the first horizontal direction. The screw of the second extrusion bolt 6 penetrates the side wall of the mold frame 1 and is threadedly connected to the mold frame 1, and the second extrusion bolt 6 abuts against one of the second baffles 5. When the first extrusion bolt 4 extrudes one of the first baffles 3, the other first baffle 3 will extrude the mold frame 1 along the first horizontal direction, and the two first baffles 3 clamp the extrusion unit 2 along the first horizontal direction; when the second extrusion bolt 6 extrudes one of the second baffles 5, the other second baffle 5 will extrude the mold frame 1 along the second horizontal direction, and the two second baffles 5 clamp the extrusion unit 2 along the second horizontal direction. Thus, the extrusion unit 2 and the mold frame 1 are assembled together. In this embodiment, the first baffle 3 is perpendicular to the first horizontal direction, the second baffle 5 is perpendicular to the second horizontal direction, the first extrusion bolt 4 is arranged along the first horizontal direction, and the second extrusion bolt 6 is arranged along the second horizontal direction. The first pressure head 201 and the second pressure head 202 have the same length along the second horizontal direction.

[0039] In some embodiments, see Figure 1 The first extrusion bolt 4 is provided with at least two bolts, thereby increasing the reliability of the extrusion unit 2 after it is assembled with the mold frame 1.

[0040] In some embodiments, see Figure 1 The second extrusion bolt 6 is provided with at least two bolts, thereby increasing the reliability of the extrusion unit 2 after it is assembled with the mold frame 1.

[0041] In some embodiments, see Figure 3 and Figure 8The two first baffles 3 and the two second baffles 5 form a receiving space 503, with the upper and lower ends of the receiving space 503 located above and below the mold frame 1, respectively. Thus, the limiting effect of the first baffles 3 and the second baffles 5 prevents the mold frame 1 from being squeezed, thereby preventing damage to the mold frame 1.

[0042] In some embodiments, see Figures 3 to 5 The first pressure head 201 and the second pressure head 202 are both partially inserted into the receiving space 503. In this way, the extrusion unit 2 can be hot-pressed in the vertical direction.

[0043] Based on the same inventive concept, see [link to inventive concept] Figure 2 , Figure 9 , Figure 10 and Figure 12 This application embodiment also provides an assembly fixture for assembling the aforementioned hot press mold for forming diamond cutting heads, including a base plate 7. The base plate 7 is horizontally arranged and used to support the mold frame 1. The upper surface of the base plate 7 is provided with a first receiving groove 71, and the bottom wall of the first receiving groove 71 is used to support the first baffle 3 and the second baffle 5.

[0044] Compared with the prior art, the solution shown in this application embodiment places the mold frame 1 on the base plate 7, and then places the two first baffles 3 and the two second baffles 5 on the bottom wall of the first receiving groove 71. In this way, the positional relationship between the first baffles 3 and the second baffles 5 and the mold frame 1 in the vertical direction can be positioned, so that the upper end and the lower end of the receiving space 503 are located above and below the mold frame 1, respectively.

[0045] In some embodiments, see Figures 9 to 11 The bottom wall of the first receiving groove 71 is provided with a second receiving groove 72. The second receiving groove 72 is used to support the second pressure head 202 in the first extrusion group 21, thereby positioning the first extrusion group 21 in the vertical space.

[0046] In some embodiments, see Figure 2 The assembly fixture also includes multiple spacers 8. The multiple spacers 8 are arranged at intervals along the first horizontal direction. The spacers 8 are perpendicular to the first horizontal direction. The spacers 8 are used to insert the second pressure head 202 of the first extrusion group 21 between two adjacent spacers 8, thereby preventing the second pressure head 202 from tipping over. The second pressure head 202 of the second extrusion group 22 is placed on the spacers 8, thereby positioning the second extrusion group 22 in the vertical space.

[0047] In this embodiment, after the second pressure head 202 in the first extrusion group 21 is inserted between two adjacent spacers 8, the second pressure head 202 is higher than the spacers 8.

[0048] In some embodiments, see Figure 2There is a gap between the two side walls of the partition plate 8 and the second receiving groove 72 in the second horizontal direction. When the second pressure head 202 in the first extrusion group 21 is inserted between two adjacent partition plates 8, the second pressure head 202 slides and fits against the two side walls of the second receiving groove 72 in the second horizontal direction, so that it can be clamped by the two second baffles 5.

[0049] When using this assembly fixture, the mold frame 1 is placed on the base plate 7, and a second pressure head 202 from the first extrusion group 21 is inserted between every two adjacent partition plates 8, so that the second pressure head 202 is placed on the bottom wall of the second receiving groove 72. Two first baffles 3 and two second baffles 5 are placed on the bottom wall of the first receiving groove 71. A second pressure head 202 from the second extrusion group 22 is placed on each partition plate 8. The cutter blank 9 and the first pressure head 201 from the first extrusion group 21 are placed on the second pressure head 202 in the first extrusion group 21 in turn. The second extrusion bolt 6 causes the two second baffles 5 to initially clamp the assembled first pressure head 201 and second pressure head 202. After flipping the entire assembly, the tooling can be removed, or the assembled parts of the mold can be detached from the assembly tooling and flipped. The first extrusion bolt 4 causes the two first baffles 3 to initially clamp the assembled first pressure head 201 and second pressure head 202. Then, the cutter blank 9 and the first pressure head 201 of the second extrusion group 22 are placed on the second pressure head 202 in the second extrusion group 22. Then, the first extrusion bolt 4 and the second extrusion bolt 6 cause the two first baffles 3 and the two second baffles 5 to tighten the extrusion unit 2 with a certain clamping force. Of course, the usage steps of this tooling can be adjusted, deleted, or other steps can be added according to the operator's habits.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
