Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, in particular to a molding device used for diode processing. Background Art

[0002] A diode is an electronic component made of semiconductor material with two electrodes, namely the positive electrode (anode) and the negative electrode (cathode). The main feature of a diode is its unidirectional conductivity. Since the PN junction inside the diode (composed of a positive semiconductor and a negative semiconductor) has a special electronic structure and potential difference, current can only flow from the positive electrode to the negative electrode.

[0003] A molding device is required for the production and processing of diodes to mold them. Generally, a molding device uses two molds, which are assembled, and liquid is injected into the inside, and then left to cool. After molding, the workpiece needs to be removed with the help of auxiliary tools to lift or pull the workpiece out. This method may cause certain damage to the workpiece and reduce the good rate of molded products. At the same time, the liquid is left to cool, which takes a long time to produce and has low production efficiency. Utility Model Content
