Technical Field

[0001] The utility model relates to the technical field of heat pipe forming, in particular to a heat pipe forming die. Background Art

[0002] Common heat pipes have a flattened setting. Flattened heat pipes can improve heat dissipation performance, reduce size or facilitate installation according to specific application requirements, thereby better meeting engineering design requirements.

[0003] However, the current flattened heat pipe forming mold has certain disadvantages. After the heat pipe is flattened in the groove of the flattening mold, it is inconvenient to remove the flattened heat pipe due to changes in shape and volume, which brings trouble to the staff in removing the material. For this reason, the present application proposes a heat pipe forming mold. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a heat pipe forming die.

[0005] The embodiment of the utility model provides a heat pipe forming mold, comprising:

[0009] Furthermore, four guide columns are fixed to the upper end of the lower die, and four guide grooves are provided at the bottom of the upper die, and the guide columns are arranged in coordination with the guide grooves.

[0010] Furthermore, the thickness of the die convex strips and the flat blocks are the same.

[0011] Furthermore, the thickness of the die convex strip is smaller than the depth of the die concave groove.

[0012] Furthermore, the length of the flat groove is greater than the width of the die groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] According to the utility model, when the heat pipe is flattened, the end of the heat pipe is located in the flat groove, but there is still space at both ends, which is convenient for removing the flattened heat pipe. In this way, the simple flat groove not only solves the disadvantage of removing the flattened heat pipe, but also has a simple structure and does not affect the flattening of the heat pipe.

[0018] In the above drawings: 1 base, 2 support column, 3 mounting plate, 4 hydraulic cylinder, 5 upper die, 6 lower die, 7 control button, 8 guide column, 9 die groove, 10 flat groove, 11 die convex strip, 12 flat block, 13 guide groove. DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a heat pipe forming mold, comprising:

[0021] Base 1;

[0022] Mold assembly; the mold assembly includes a lower mold 6 installed on the base 1, and a die groove 9 is provided on the lower mold 6. A flat groove 10 is provided on the lower mold 6 and is located at the end of the die groove 9 and is connected to the die groove 9. The length of the flat groove 10 is greater than the width of the die groove 9. Therefore, when the heat pipe is flattened, the end of the heat pipe is located in the flat groove 10, but there is still space at both ends. This space is convenient for removing the flattened heat pipe. In this way, the simple flat groove 10 not only solves the disadvantage of removing the flattened heat pipe, but also has a simple structure and does not affect the flattening of the heat pipe.

[0023] An upper mold 5 that can move up and down is provided above the lower mold 6, and four support columns 2 are installed on the base 1. A mounting plate 3 is fixed to the upper ends of the four support columns 2, and a hydraulic cylinder 4 is installed on the mounting plate 3. The output end of the hydraulic cylinder 4 is fixedly connected to the upper end of the upper mold 5, and the upper mold 5 can be driven to move up and down by the hydraulic cylinder 4; wherein, two control buttons 7 are installed on the base 1, and pressing the two control buttons 7 at the same time can control the hydraulic cylinder 4 to work, which is safer to use.

[0024] The upper mold 5 is provided with a mold convex strip 11 that cooperates with the mold groove 9, and a flat block 12 that cooperates with the flat groove 10 is fixed at the end of the mold convex strip 11. The thickness of the mold convex strip 11 and the flat block 12 are the same, and the thickness of the mold convex strip 11 is less than the depth of the mold groove 9. In this way, when the upper mold 5 and the lower mold 6 are abutted, the mold convex strip 11 is located in the mold groove 9, and the space between the mold convex strip 11 and the mold groove 9 is the space after the heat pipe is flattened.

[0025] In order to ensure that the upper mold 5 and the lower mold 6 are stably facing each other, that is, to ensure that the die convex strip 11 is facing the die groove 9, four guide columns 8 are fixed to the upper end of the lower mold 6, and four guide grooves 13 are provided at the bottom of the upper mold 5, and the guide columns 8 and the guide grooves 13 are arranged in cooperation with each other; as the upper mold 5 moves downward, the guide grooves 13 at the bottom of the upper mold 5 are sleeved on the guide columns 8, so that the guide grooves 13 cooperate with the guide columns 8 to ensure the stable and facing movement of the upper mold 5 and the lower mold 6.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
