Description

Technical Field

[0001] The present application relates to the technical field of mold line grinding of plastic parts, and in particular to a vibration grinding structure for the mold line of a square injection molded part. Background Art

[0002] The parting line of injection molded parts is also called the overflow line. It is the visible mark left after the overflow is cut off when excess plastic flows out of the mold joint. It is because the plastic is pressurized to fill the mold during injection. No matter how tight the mold is, the plastic will still form a gap where the mold is separated or combined, and will be squeezed into this gap to a greater or lesser extent. When the molded product is taken out of the mold, it will leave a mark on this gap. This is the parting line. For the beauty and sealing of the plastic part, it is usually necessary to grind it off.

[0003] In the prior art, after the plastic parts are stitched, the staff uses a handheld grinding device to grind the mold line and remove excess burrs on it, thereby improving the precision and aesthetics of the plastic parts. Usually, the plastic parts are fixed by a clamp and then polished by a grinding disc. When polishing some square plastic parts, the position where the plastic parts are fixed by the clamp cannot be polished, so they need to be replaced and fixed after half of the grinding, which results in low efficiency.

[0004] Therefore, a vibration grinding structure for the mold line of square injection molded parts is needed. Utility Model Content
