Flattening mould with cooling cycle system

Abstract

The invention discloses a flattening mould with a cooling cycle system. The flattening mould with the cooling cycle system comprises an upper mould holder connected with a punch press upper slider, a lower mould holder mounted on a punch press workbench, a punch fixing plate mounted under the upper mould holder, an unloading plate mounted under the punch fixing plate, a flattening punch fixed onto the punch fixing plate, and a cavity mould plate above the lower mould holder. The flattening mould with the cooling cycle system is characterized in that the unloading plate is provided with an unloading insert, and a water circulation system is formed inside the insert and connected with a cooling water circulation system. The flattening mould with the cooling cycle system can rapidly cool the mould and the punch through the build-in cooling cycle system to avoid uneven flattening thickness due to heating of the punch; the water circulation channel is arranged on the unloading plate without direct contact with the mould, thereby reducing the possibility of water leakage and fault of the mould, facilitating disassembly and cleaning and greatly prolonging the service life of the mould.

Description

technical field [0001] The invention relates to a stamping die, in particular to a flattening die with a cooling circulation system. Background technique [0002] On stamping molds such as flattening dies, due to the large amount of flattening of the material, the punch and the product will heat up severely, which will cause the flattened thickness to be unstable. By cooling the mold, the mold can be kept at an appropriate temperature, which is beneficial to ensure the quality of the molded product and improve the efficiency of mold molding. The traditional cooling method is to use gas cooling technology to process air holes and air on the mold. The cooling gas is sprayed onto the surface of the workpiece to realize the gas quenching effect on the workpiece. This type of mold has a complex structure and high cost, and there are many inconveniences in the preparation, storage, and transportation of the cooling gas during use. Another method is water cooling technology. A wat...

[0002] On stamping molds such as flattening dies, due to the large amount of flattening of the material, the punch and the product will heat up severely, which will cause the flattened thickness to be unstable.

By cooling the mold, the mold can be kept at an appropriate temperature, which is beneficial to ensure the quality of the molded product and improve the efficiency of mold molding. The traditional cooling method is to use gas cooling technology to process air holes and air on the mold. The cooling gas is sprayed onto the surface of the workpiece to realize the gas quenching effect on the workpiece. This type of mold has a complex structure and high cost, and there are many inconveniences in the preparation, storage, and transportation of the cooling gas during use.

Another method is water cooling technology. A water tank is set in the die seat, and the quenching of the parts is realized by directly contacting the cooling water with the mold components. This method is prone to water leakage, because both the mold and the parts belong to metal tools. , if the water leakage is not cleaned up in time, the service life and production efficiency of the mold and parts will be greatly reduced, and the maintenance will be difficult
