Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter stamping die technology, and in particular to a cooling structure for metal stamping dies. Background Technology

[0002] Photovoltaic inverters are key technical equipment in photovoltaic power generation systems. They convert the direct current (DC) electricity generated by photovoltaic panels into alternating current (AC) electricity, which can then be safely supplied to the power grid or for residential and commercial use. Stamping dies used in the machining of photovoltaic inverter parts are crucial tools for producing the various metal components within the inverter.

[0003] The cooling structure of the stamping dies used in the traditional processing of photovoltaic inverter parts is usually a single heat dissipation structure with limited heat dissipation capacity, resulting in low heat dissipation efficiency of the die plate.

[0004] Therefore, those skilled in the art have provided a cooling structure for metal stamping dies to solve the problems mentioned in the background art. Utility Model Content

After heat exchange, the cooling water is sent back to the water tank 3 after heat exchange through the heat exchanger 5, and the cycle continues. At the same time, the heat dissipation plate 2 at the bottom of the fixed template 1 increases the contact area with the air, thereby improving the heat dissipation effect.

After the stamping is completed, the compressed workpiece is sent into the fixing groove 16 through the air passage 17 by the operation of the air pump 15, thereby compressing the return spring 20 and pushing the push rod 18 upward. The ejector plate 19 ejects the workpiece. This structural design can realize the automatic demolding process of the workpiece, making it convenient for the operator to remove the workpiece from the mold cavity of the fixed template 1. Fixing blocks 12 are designed in the middle of both sides of the fixed template 1 and the middle of both sides of the heat sink 2. Two fixing blocks 12 on the same side are connected by connecting bolts 13. Bolts 13 are used for connection to facilitate the connection between the fixed template 1 and the heat sink 2.

At the same time, the heat dissipation plate 2 at the bottom of the fixed mold plate 1 increases the contact area with the air, thereby improving the heat dissipation effect.

After the stamping is completed, the compressed workpiece is sent into the fixed slot 16 through the air passage 17 by the air pump 15, thereby compressing the return spring 20 and pushing the push rod 18 to move upward. The ejector plate 19 ejects the workpiece. After the workpiece is removed, the rebound force of the return spring 20 causes the ejector plate 19 to return to its original position. This part of the structural design can realize the automatic demolding process of the workpiece, making it convenient for the staff to remove the workpiece from the mold cavity of the fixed mold plate 1.
