Description

Technical Field

[0001] This utility model relates to overflow removal equipment, and more particularly to an automatic dry ice overflow removal equipment for metal powder injection molded parts. Background Technology

[0002] Conventionally, flash in metal powder injection molded parts is removed manually. The disadvantages of this method are that it is labor-intensive, physically demanding, and inefficient.

[0003] Application No. 202210211443.X discloses a device and method for removing overflow in semiconductor chip packaging, comprising a lower support and an upper support. A lower pressure block is movably mounted on the surface of the lower support, and pins are respectively placed on both sides of the lower pressure block above the lower pressure block. The pins are movably mounted to the lower support. An upper pressure block is placed on the surface of the lower pressure block. A driving cavity is formed in the inner wall of the upper support, and an anti-slip rod is movably mounted in the middle of the bottom end of the upper support. This invention provides anti-overflow baffles on both sides of the upper pressure block. By having the anti-overflow baffles adhere to both sides of the upper pressure block, during the process of the upper pressure block adhering to the lower pressure block, the extruded injection molding compound is output from the feed hole on the anti-overflow baffle. After processing is completed, the injection molding compound in the feed hole is broken, thus preventing excess injection molding compound from appearing on both sides of the upper pressure block, thereby protecting the pins from damage and ultimately achieving the purpose of removing overflow.

[0004] However, the aforementioned overflow removal device is applicable to the field of chip packaging technology, mainly for removing excess injection plastic residue on the pins on both sides of the chip after injection molding, and is not applicable to overflow removal of metal powder injection molded parts.
