Description

Technical Field

[0001] This utility model belongs to the field of cold heading technology, specifically relating to a heat dissipation type cold heading mold. Background Technology

[0002] Cold heading is a cold stamping process in which pressure is applied to metal at room temperature using a die to achieve plastic deformation. It is mainly used for forming the heads of fasteners such as screws, bolts, and rivets. Prolonged impact and pressure can generate a large amount of heat, affecting the forming effect of the die itself. Therefore, obtaining a heat-dissipating cold heading die is crucial. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a heat dissipation type cold heading die, comprising:

[0004] The heat dissipation base has several mounting grooves on it;

[0005] Several cold heading dies, at least part of the outer wall of which is adapted to the shape of the mounting groove, are detachably connected to the heat dissipation base by bolts;

[0006] Each of the mounting grooves has a first inlet and a first outlet on its placement surface. The cold heading mold has a spiral channel, and the two ends of the spiral channel extend to the bottom surface of the cold heading mold to form a second inlet that mates with the first inlet and a second outlet that mates with the first outlet, respectively.

[0007] The heat dissipation substrate is provided with a total inlet and a total outlet. The total inlet is connected to a number of first inlets, and the number of first outlets converges and connects to the total outlet.

[0008] The heat dissipation substrate has an avoidance channel for the operation of the mold ejector rod.

[0009] Through the above technical solution, the present invention has a simple structure, which includes several cold heading dies to adapt to cold heading production lines. Furthermore, since the cold heading dies and the heat dissipation base are detachable, different cold heading dies can be replaced as needed, making it more widely applicable.

[0010] Preferably, a first annular groove is formed on the circumference of the first inlet, and a first sealing ring is installed in the first annular groove; a second annular groove is formed on the circumference of the first outlet, and a second sealing ring is installed in the second annular groove.

[0011] Through the above technical solution, since the mounting groove and at least part of the outer wall of the cold heading mold are adapted, the positioning function can be realized, so that the first inlet and the second inlet can be adapted and positioned, and the sealing connection can be realized through the deformation of the first sealing ring and the second sealing ring to prevent water leakage.

[0012] Preferably, the total outlet and the total inlet are located on opposite sides of the width of the heat dissipation substrate.

[0013] With the above technical solution, the total outlet and the total inlet can be connected to water pipes respectively.

[0014] As a preferred embodiment, the spiral channel is replaced with a cylindrical channel, resulting in a larger heat dissipation area.

[0015] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and can dissipate heat during the cold heading process, preventing long-term processing from affecting the mold and the yield of the product. Attached Figure Description

[0035] Through the above technical solution, since the mounting groove 11 and at least part of the outer wall of the cold heading mold 2 are adapted to each other, the positioning function can be realized, so that the first inlet 12 and the second inlet 21 can be adapted and positioned, and the sealing connection can be realized through the deformation of the first sealing ring 24 and the second sealing ring 25 to prevent water leakage.

[0036] Preferably, the total outlet 15 and the total inlet 14 are located on both sides of the width direction of the heat dissipation substrate 1.

[0037] Through the above technical solution, the total outlet 15 and the total inlet 14 can be connected to water pipes respectively.
