Technical Field

[0001] The utility model relates to the field of heat sink production, in particular to a forming die used for heat sink production. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer uses a fairly large heat sink, as do the power tubes, line tubes, and amplifier tubes in a TV. Generally, a heat sink should be coated with a layer of thermal conductive silicone grease on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the components can be more effectively transferred to the heat sink, and then dissipated to the surrounding air through the heat sink.

[0003] In the prior art, the production of heat sinks requires the use of copper sheets or aluminum sheets which are then formed by die stamping.

[0004] However, after the heat sink is formed, the worker needs to manually take out the formed heat sink in the device, and needs to repeatedly put his hands in the working range of the device, which can easily cause damage to the worker's hands when the machine is working, which has low safety and low practicality.
