The Daily Necessities Mould has six systems, and the guide system is set up to ensure that the moving mould and the fixed mould can be accurately centred when closing the mould. The guide components must be set up in the daily necessities mould. Four sets of guide posts and guide sleeves are usually used to form guide parts in injection moulds for daily necessities. Sometimes, the movable mould and the fixed mould need to be respectively provided with mutually matched inner and outer conical surfaces to assist in positioning.

The guide pillar mainly plays a guiding role in the daily necessities mould to ensure that the moulding surfaces of the core and the cavity do not touch each other under any circumstances, and the guide pillar cannot be used as a force bearing member or a positioning member. How to deal with the damage of the guide pillar during the use of the injection mould for daily necessities?

In several cases, when injecting, the moving and fixed dies will produce huge lateral deflection force. When the wall thickness of the plastic parts is not uniform, the flow rate through the thick wall is high, resulting in greater pressure. The sides of the plastic parts are asymmetrical, such as the daily necessities mould with stepped parting surface, and the opposite two sides are subjected to unequal back pressures.

In order to produce a set of high-quality injection daily necessities mould, injection mould factories need to understand every detail in the design, manufacture and moulding of each set of moulds and understand the use of each part in daily necessities mould. Knowing the important role of the guide pillar in the daily necessities mould and the harm that the damage of the guide pillar brings to the entire daily necessities mould will better pay attention to such problems in subsequent use, not only an excellent plastic products be better manufactured, but also the service life of the injection daily necessities mould is greatly prolonged.
