Vent of injection mold
The vent of the injection mold is a grooved air outlet opened in the mold to discharge the original gas and the gas brought in by the molten material.When molten material is injected into the mold cavity, the air originally stored in the mold cavity and the gas brought in by the melt must be discharged from the mold through the exhaust port at the end of the material flow, otherwise, the products will have air holes, poor connection, mold filling dissatisfaction, or even the products will be burned due to high temperature accumulated air caused by compression.In general, the vent can be located at the end of the molten flow in the mold cavity, or on the parting surface of the mold.The latter is a deep 0 on the die side.03-0.2mm wide by 1.Shallow grooves of 5-6mm.During the injection, the vent will not have much molten material seeping out, because the molten material will cool and solidify in this place and block the passage.Do not open the vent to the operator to prevent accidental discharge of molten metal injury.In addition, may also use the ejector rod and the ejector hole matching clearance, the ejector block and off the template and core matching clearance to exhaust.
