  • Description: During the injection moulding of the Dustbin Mould(FURNITUREMOULD) https://www.furnituremould.com/ , the gate sometimes sticks to the gate bushing and is not easy to come out. Crack damage to the product during mould opening. The operator must use the tip of the copper rod to knock out the nozzle to loosen the broken plastic before demolding, which seriously affects production efficiency. The main reason for this failure is that the tapered bore surface of the sprue bush has a poor finish and sometimes the bore has a knife mark in the circumferential direction. Secondly, if some of the injection moulding material is too soft, the small end of the tapered hole of the dustbin mould will be deformed or damaged after a period of use. If the nozzle curvature of the gate casing is too small, the gate feed will create a rivet head there. The taper of the gate bushing is difficult to machine. Standard parts should be used whenever possible. If you need to handle it yourself, you can also use or purchase a special reamer. The guide post is mainly used to fix and guide the dustbin mould to ensure that the core and cavity forming parts of the dustbin mould do not collide with each other under any circumstances, but the guide post must not be used as a force point or to position the dustbin mould. portion. For example, when moving and fixing the mould, a large lateral biasing force is generated: when the wall thickness of the plastic member is uneven, the flow rate of the material passing through the thick wall is large, and the pressure is large. Generated here; if the sides of the plastic part are asymmetrical, such as a mould with a stepped profile, the opposing pressures on opposite sides of the dustbin mould are not equal.
