A estrutura funcional do sistema de molde de plástico é composta principalmente por seis sistemas: sistema de vazamento, sistema regulador de temperatura, formando sistema de peças, sistema de exaustão, sistema de orientação e sistema de ejeção. O sistema de vazamento e as peças formadoras são as peças em contato direto com os plásticos, e mudar com plásticos e produtos. Eles são as peças mais complexas e mais mutáveis no molde de plástico. É necessário processar as peças com a mais alta suavidade e precisão.
- Sistema de portas:
The pouring system refers to the runner part of the plastic before it enters the cavity from the nozzle, incluindo o corredor principal, the cold material hole, the shunt runner and the gate, etc.
- Molding parts system:
The forming part system refers to the combination of various parts which constitute the shape of the product, including the movable die, the fixed die, a cavidade (concave die), the core (soco), the forming rod and so on. The core forms the inner surface of the product, and the cavity (die) forms the outer surface shape of the product. After closing, the core and cavity form the cavity of the die. According to the process and manufacturing requirements, sometimes the core and die are composed of several pieces, sometimes they are made into a whole. Inserts are used only in the parts that are easy to be damaged and difficult to be machined.
- Temperature control system:
Temperature control system is to meet the requirement of injection process for mould temperature. Temperature control system is needed to adjust the temperature of the mould. For injection moulds for thermoplastics, cooling systems are mainly designed to cool the moulds (or to heat the moulds). The common method of mould cooling is to set up cooling water passage in the mould and use circulating cooling water to take away the heat of the mould; besides using cooling water to pass hot water or hot oil, the heating of the mould can also install electric heating elements inside and around the mould.
- Exhaust system:
The exhaust system is set up to exclude the air in the cavity and the gas produced by the melting of plastic into the outside of the mould during the injection moulding process. When the exhaust is not smooth, the surface of the product will form bad gas marks (gas lines), burning and so on. The exhaust system of the plastic mould is usually a groove-shaped air outlet opened in the mould to discharge the original type. The air in the chamber and the gas brought in by the melt.
Quando o fundido é injetado na cavidade, the air in the cavity and the gas brought in by the melt must be discharged out of the die through the exhaust port at the end of the material flow. Por outro lado, the product will have air holes, poor connection, unsatisfactory filling, and even the accumulated air will burn the product due to high temperature caused by compression. Em geral, the exhaust holes can be located at the end of the melt flow in the cavity or on the parting surface of the plastic mould.
The latter is a shallow groove with a depth of 0.03-0.2 mm and a width of 1.5-6 mm on the side of the die. During the injection, the exhaust holes will not have a lot of melt seepage, because the melt will cool and solidify there and block the passage. The opening position of the exhaust outlet should not be directed at the operator in order to prevent accidental ejection of molten material from hurting people. Além disso, the matching clearance between ejector rod and ejector hole, and the matching clearance between ejector block and ejector template and core can also be used to exhaust gas.
5, Guidance system:
The guiding system is set up to ensure that the moving and fixing die can be accurately aligned in the die. The guiding parts must be set up in the die. In injection moulds, four groups of guide pillars and guide bushes are usually used to form guide parts. As vezes, the internal and external cones which coincide with each other are set on the dynamic and fixed moulds to assist in positioning.
- Sistema de ejeção:
Ejection system generally includes: ejection pin, front and rear ejection pin plate, ejection pin guide rod, ejection pin reset spring, ejection pin plate locking screw and other parts. When the product is cooled in the mould, the front and rear die of the mould are separated and opened, and the plastic product and its condensate in the runner are pushed out or pulled out by the ejector pin driven by the ejector rod of the injection machine, so as to carry out the next injection molding working cycle.
