Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a multifunctional integrated extension die. Background Art

[0002] A drawing die is a die element used in cold stamping processes, mainly used to stretch flat metal sheets into parts of various shapes, such as bowls, plates, cups, basins, etc. When designing a drawing die, several factors need to be considered to ensure processing quality and efficiency.

[0003] For example, in order to prevent burning, damage to the lubricating oil film and reduce ejection force, high-viscosity lubricating oil is usually applied to the die to reduce friction during the extension process and overcome the phenomenon of die sticking and bottom cracking. At the same time, the extension die will generate high temperature during use. In order to prevent early fracture or other defects caused by high temperature, appropriate cooling measures need to be taken.

[0004] However, when the stamping production mold needs to be replaced during the production process, the cooling water pipe and lubrication pipe on the mold need to be disassembled and installed on the new mold, resulting in the defect of inconvenient operation when replacing the mold.

[0005] Based on this, the utility model designs a multifunctional integrated extension die to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional integrated extension die to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a mounting block, a mounting hole is provided on the mounting block, a cooling groove is provided in the mounting hole, a water inlet and a water outlet are provided on the mounting block, and the water inlet and the water outlet are respectively connected to the cooling groove; a forming mold and a guide mold are plugged into the mounting hole, the forming mold is provided with a forming hole, the guide mold is provided with a guide hole, a through groove is provided on the side of the guide mold close to the forming mold, an injection groove is connected between the guide hole and the through groove, the injection groove is located on the side of the guide mold close to the forming mold, and the mounting block is provided with an injection hole; when the forming mold and the guide mold are plugged and arranged on the mounting block, the injection hole is connected to the through groove; a fixing hole is provided on the mounting block, and a plurality of fixing holes are provided.

[0008] By adopting the above technical solution, a forming die and a guide die are plugged into the mounting block, a cooling device is installed on the forming die, and a lubrication device is installed on the guide die, so that when the mold is replaced, only the forming die and the guide die need to be disassembled and assembled to complete the operation of replacing the mold.

[0009] Preferably, a lead seal is fixedly arranged in the cooling tank.

[0010] By adopting the above technical solution, the setting of the lead seal restricts the flow direction of water in the cooling tank, thereby avoiding insufficient water supply at the far end, which leads to a decrease in heat dissipation capacity and causes heat accumulation in the molding die.

[0011] Preferably, the lead seal is fixedly arranged on one side of the cooling tank close to the water inlet and the water outlet.

[0012] By adopting the above technical solution, the lead seal increases the range of cooling water flowing in the cooling groove, increases the contact area with the forming mold, and improves the heat dissipation capacity of the forming mold.

[0013] Preferably, a plurality of injection grooves are provided, and the plurality of injection grooves are evenly distributed circumferentially on the guide mold.

[0014] By adopting the above technical solution, the setting of multiple injection grooves allows the raw material to fully contact with the grease after passing through the guide hole of the guide die during stamping, thereby improving the surface quality of the molded workpiece and preventing extension fracture.

[0015] In summary, the present application has the following beneficial technical effects: a forming die and a guide die are plugged into the mounting block, so that during the stamping operation, under the action of the guide hole, the product raw material is guided into the die, and the extended product can be accurately deformed without being skewed; at the same time, a cooling device is installed on the forming die, and a lubrication device is installed on the guide die, so that when the mold is replaced, only the forming die and the guide die need to be replaced and disassembled to complete the operation of replacing the mold, avoiding the connection and complicated disassembly of various traditional pipelines, and has the advantage of simplifying the operation process when replacing the mold.
