Description

Technical Field

[0001] This utility model relates to the field of air conditioner fin processing technology, and in particular to a cooling mechanism and forming mold. Background Technology

[0002] The forming process of air conditioner fins typically involves 5 to 10 steps of forming protrusions. During production, the mold is used to simultaneously form several or dozens of rows of fins, and the stamping speed is generally above 250 to 300 times per minute. The aluminum foil material deforms and flows along the direction of force at the upward forming point, thus forming a protruding structure. The aluminum foil material protrusion forming structure is as follows... Figure 8 As shown.

[0003] During this process, high-strength stamping oil is needed to lubricate the punch and die to promote material flow, reduce friction, and enable the forming bulge to reach a higher value. It can also prevent material scratches during the stretching process, which would affect the quality of the fins. At the same time, a lot of heat is generated during the stamping process. If the heat cannot be dissipated quickly, the mold temperature will rise significantly, affecting the mold size. In severe cases, it can cause misalignment of the punch and die, resulting in chipping of the cutting edge. In addition, the increased temperature will also accelerate the wear of the punch and die, affecting the service life of the mold. Utility Model Content

At the same time, stamping oil can increase lubrication, reduce wear on the packing punch 220 and die, and increase the service life of the die. It can also prevent scratches on the aluminum foil flow surface, which would affect the fin forming quality. In addition, because stamping oil is volatile, it generates a lot of heat during the stamping process, which helps to reduce the temperature of the packing punch 220 and die, playing a cooling role and improving the service life of the die.

At the foil initiation point, the material flow is promoted during the forming process, which helps to maximize the forming bulge and solves the problem of insufficient high flange amount, ensuring smooth forming of aluminum foil material. At the same time, the stamping oil can increase lubrication, reduce wear on the packing punch 220 and the die, and increase the service life of the mold. It can also prevent scratches on the aluminum foil flow surface, which would affect the fin forming quality. In addition, because the stamping oil is volatile, it generates a lot of heat during the stamping process, which helps to reduce the temperature of the packing punch 220 and the die, thus playing a cooling role and improving the service life of the mold.

The elastic member 260 can drive the stripper plate 250 to move away from the lower template 210. After the aluminum foil is convexly formed, the upper mold base will move away from the lower mold base 230. At this time, the elastic force of the elastic member 260 drives the stripper plate 250 away from the lower template 210, thereby completing the separation of the aluminum foil from the packing punch 220 and completing the unloading of the aluminum foil.

[0090] Specifically, the lower template 210 is provided with guide posts 215, and the unloading plate 250 is provided with guide holes 251. The guide posts 215 and the guide holes 251 cooperate to ensure that the unloading plate 250 can be raised and lowered on the lower template 210.
