Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a stamping mold. Background Art

[0002] A stamping die is a special process equipment used in cold stamping to process metal or non-metal materials into parts. Its working principle is to use a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.

[0003] In the production of automobile parts, stamping dies are mostly used for stamping. When the stamping die is performing stamping operations, the high-frequency stamping of the dynamic die and the static die will generate a lot of heat. If the heat is not dissipated in time, it will affect the production quality of the parts. For example, the utility model patent: A stamping die with cooling function (Announcement No.: CN219093374U) discloses a water tank, a water pump and a hose. When the temperature of the upper die and the lower die is high, the water pump can be started to spray coolant to cool the upper die and the lower die. The baffle and the guide hole are set so that the coolant can flow back into the water tank for reuse. The first filter plate and the second filter plate are set so that the iron filings and impurities in the refluxed coolant can be adsorbed. However, the structure of this stamping die that plays a cooling and heat dissipation role needs to occupy a large layout space, which is not convenient for installing the stamping die on a press for application.

[0004] In view of the above problems, the present invention makes improvements. Utility Model Content

[0024] Specifically, the cooling copper bar 32 is provided with a plurality of water holes 3211 which penetrate the cooling copper bar 32 along the length direction of the cooling copper bar 32. The ports of adjacent water holes 3211 are connected via a transfer tube 3212, so that the water holes 3211 are connected with the transfer tube 3212 to form a cooling water path 321. The transfer tube 3212 and the water receiving pipe 322 are connected to the ports of the water holes 3211 by screwing. The above structure facilitates the processing and forming of the cooling water path 321, and after the transfer tube 3212 is removed from the ports of the water holes 3211, it is convenient to clean the cooling water path 321.

[0025] In the above embodiment, the fixing frame 31 is fixedly connected to the movable template 1 or the static template 2 by the cooperation of the fixing bolts 34 respectively located above and below the side ends of the movable template 1 or the static template 2 and abutting against the movable template 1 or the static template 2, so that the cooling copper bar 32 is fixed to the side end surface of the movable template 1 or the static template 2 with the fixing frame 31 and keeps in contact with the movable template 1 or the static template 2. When using this stamping die, the static template 2 and the movable template 1 fixedly connected with the cooling assembly 3 are directly set on the press, and the water pipe 322 is connected to the external coolant pumping device through a hose. The coolant is pumped for circulation in the cooling water path 321 by the pumping device, and the movable template 1 is under the action of the press.
