Circulating convection cooling device for machining stamping die

Abstract

The invention provides a circulating convection cooling device for a machining stamping die. The circulating convection cooling device comprises a rectangular plate, an exhaust groove B and a water inlet pipe. Seven rectangular holes are formed on the front end face of the rectangular plate in a rectangular array shape, and a plurality of supporting blocks are welded to the front end face of the rectangular plate. The rear end face of the rectangular plate is fixedly connected with a rectangular base through bolts, two fan mounting holes used for mounting fans are symmetrically formed on the front end face of a rectangular base, and a layer of iron gauze is mounted on the fan mounting holes. According to the present invention, a rectangular clamping plate is arranged, and thirteen air outlet holes for exhausting air are formed on the front end surface of the rectangular clamping plate and are of the trapezoidal structures, so that the strength of the rectangular clamping plate is guaranteed while the air outlet efficiency of the air outlet holes is guaranteed; the front end face of the rectangular clamping plate makes contact with the die, part of heat on the die can be taken awayduring the circulation and exhaust process of air through the exhaust grooves B, so that the heat dissipation effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of mold cooling, and more specifically relates to a circulation type convection cooling device for machining stamping molds. Background technique [0002] In the process of mechanical processing, stamping is a commonly used processing method. In the process of stamping, the temperature of the mold is likely to rise due to friction, which affects the service life of the mold and the stamping accuracy. [0003] For example, the application number: CN201611212232.9, the invention discloses a mold cooling device, including a frame, a square mold is arranged on the frame, a frame is slid on the frame, and a first water storage chamber is slid in the frame, The second water storage chamber and the third water storage chamber, a connected water pump and a cooling water tank are connected between the first water storage chamber and the third water storage chamber, the frame is connected with the first connecting rod...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a circulating convective cooling device for machining stamping dies to solve the existing problem that the overall structure of the above application is relatively large, and it is necessary to arrange various matching parts around the die, which is clean and flexible. The performance is poor, and the volume cannot be reduced by holding and fixing the fixture of the mold to improve the overall cleanliness; moreover, the cooling effect is poor, and the device cannot be directly contacted with the outer surface of the mold for cooling, and it cannot be cooled by the wind. The method of combining cold and water cooling for synergistic cooling, the problem that the cooling speed is slow and the effect is not obvious
