Description

A kind of SMC low pressure mold

Technical field

The utility model relates to technology of die manufacturing field, specially a kind of SMC low pressure mold.

Background technique

Design to SMC automobile die structure not only will use quality requirement, load bearing work according to SMC product Article shape structure is determined as situation, and will be according to the reality of molding production, on each program in the process, each influence Factor carries out necessary analysis, tradeoff, and identified article construction is made to meet the technique requirement of molding manufacture.SMC mould structure Influence to later production process is mainly manifested in the implementation of the design difficulty or ease and the process conditions in mold process of mold.Reason The mechanograph structure thought should be able to easily design and manufacture shaping mould tool, and can successfully produce good SMC molding system Product.Therefore, when determining product external structure, its simple rule should be made as far as possible under the premise of meeting using quality.Carry out When the design of SMC molded article, influence of the product shape to craftsmanship should be given one's full attention to.SMC mold is that SMC molded article is set The basic link of meter mainly includes three temperature, pressure, time factors.Molding temperature has determined mold material into die cavity Heat transfer condition, have conclusive influence to the melting of material, flowing and curing proceeding.Molding pressure is during compression molding Effect, be to make mold tight closure and make material density, and promote low-molecular material volatilization in melt flowing and balance die cavity Generated pressure.Clamp time is between mold open, and material is heated the cured time in mould, and clamp time was forming Effect in journey mainly makes the molding for obtaining mold cavity shapes have time enough to complete solidification, and solidification refers to thermosetting plastics The forming process of three-dimensional-structure when molding.

The structure of SMC low pressure mold designs: the punch-pin and cavity plate fit structure form of key technology are typically include excessive formula Mould is compressed, do not overflow formula structure and structure semi-positive.Flash mould, punch and matrix are answered smooth without cooperation, punch and matrix contact surface It is smooth, but should not be too big, it is designed to wide 3~5mm annular surface, but annular surface rapid wear in this way.Its punch-die of formula structure that do not overflow cooperates Gap and engagement height are appropriate, and too small then exhaust problem, punch and matrix easily abrades, and too big then flash is serious, the removal of overlap difficulty. Structure semi-positive its because having lateral extrusion face, compressive plane width not Ying Tai little, to bear overbottom pressure all by compressive plane, it is necessary to If pressure block, the die press technology for forming of SMC material must satisfy the presentation quality of product, mechanical property and efficient productivity. Main ingredient is unsaturated-resin in SMC material, is pressed and molded temperature between 160 DEG C -165 DEG C, high and low temperature must be 5 Within DEG C, guarantee that being heated evenly for product just can guarantee that the presentation quality of product and mechanical property reach requirement.Hot-die at present Most of tool is all using electric heating and oil two kinds of modes of heating, and because automobile product shape is relative complex, electric heater unit cannot It follows shape of product to arrange well, therefore cannot be guaranteed mold temperature control within 5 DEG C.
