What is the failure analysis and troubleshooting method for injection mold vent blocking?
In the design of die structure, the structure design of vent hole is very important. If the structure is not properly designed, it will cause obstruction.
1. Set the exhaust groove on the parting surface, preferably the shallow groove with a width of 20mm and a depth of 0.02mm, not the structure of the groove.A semicircular ring groove with a diameter of 3mm can be set around the parting surface at 2.5mm away from the shallow groove, and the ring groove should be connected with the outside world.The clearance of the ejector rod in the ejection device can also be used for exhaust.
2. The gap between the general exhaust groove or the exhaust outlet is less than an hour, which is often blocked by the residual material or mold release agent in the cavity.For this, the lotion should be cleaned thoroughly.
