Description
Technical field
The utility model relates to a kind of technical field of mold, particularly relates to a kind of lamp cap cover shell compaction forming die.
Background technology
Compression molding is a kind of important technical matters in processing and forming, has a wide range of applications, play an important role in the life of people in industrial production, industrial processes.Compression molding is the abbreviation of compression molding, also known as compression moulding.Plastics or rubber size are shaped to plastic processing (being also the rubber processing) method of goods in closed mould cavity by heating, pressurizeing.Generally by powdery, granular, Tuan Lizhuan, sheet, even first be made the material base with goods similar shape, be placed in the die cavity of the mould of heating, then mold closing pressurization, make it shaping and solidification or sulfuration, obtain goods (see figure) through the demoulding again, this method is specially adapted to the processing and forming of thermosetting plastics (see thermosetting resin).Shortcoming is that the production cycle is long, and efficiency is low, and product's dimensional precision is poor.
Capital equipment has press and mould.The effect of press is to apply pressure by mould to plastics.In rubber processing, press is called vulcanizing press.The major parameter of press comprises nominal tonnage, pressing plate size, impulse stroke and diameter of plunger, these indexs decide press can the area of pressing, height or thickness, and the maximum norm pressure pressure that can reach.Mould, by the feature of its structure, can be divided into excessive formula, excessive formula and half overflows formula three kinds, wherein with the most use with formula of partly overflowing.Technical process is divided into reinforced, mold closing, exhaust, solidification, the demoulding and mold cleaning etc., if goods have inserts to need to enclose when mold pressing, then inserts should be placed before reinforced.The process conditions of major control are pressure, mold temperature and clamp time.In addition, also have a kind of mould pressing method of special shape, namely first by powdered plastic compacting, then from mould, take out material base, be placed in stove and be heated to fusing point, make plastic grain be fused into an entirety, after cooling, obtain goods or semi-finished product.This method claims sinter molding, is mainly used in the shaping of polytetrafluoroethylene (PTFE).
It is shaping that application is mainly used in thermosetting plastics (see thermosetting resin), as plastics such as phenolic aldehyde, melamino-formaldehyde, ureaformaldehydes, also adds the reinforced plastics goods of glass fibre for the manufacture of unsaturated polyester (UP) and epoxy resin.Thermoplastic (see thermoplastic resin) also has this method of employing shaping, as polyvinyl chloride disc.But during thermoplastic mold pressing, mould must cool before article removal, before next product is shaping, mould must be reheated again, therefore production efficiency is very low.Die pressing is also a kind of epochmaking forming method in rubber industry, sizing material is cut out or is die-cut into simple shape, adds in heating mould, and sulfuration while shaping, goods are also the demouldings while hot.Many rubber cast goods such as sealing gasket, anti-vibration article (as cushion rubber, offset plate) etc. are all produced by this method.
The existing compaction forming die complex structure for lamp cap cover shell at present, install inconvenient, working (machining) efficiency is low, and heating rod is shorter for service life, and processing stability is poor.
