Description

A kind of minute surface light plastics extrusioning shaping mould
The (1) technical field: the utility model relates to the improvement technology of plastic products mould, especially a kind of minute surface light plastics extrusioning shaping mould.
The (2) background technology: the plastic extruding forming mould is of many uses, is one of important means of present plastic products processing.The extrusion molding plastic products extensively be distributed in we the life around, mould view material or the like like plastic-steel door and window, all types of plastic tubing, all kinds of decoration material, all kinds of wood, all be unable to do without the application of plastics extrusion die.The expansion of application market, competition must be upgraded.In order to adapt to market; In keen competition, obtain leading position; People are also just increasingly high to the quality requirement of plastic products, and the direct presentation quality of product is required the most important thing especially, and the important contents that presentation quality requires is exactly the form accuracy and the surface effect of extruded product.
At present, domestic plastics extrusion die manufacturing enterprise is various, but the technological innovation situation falls behind mostly, and the process for machining and manufacturing of mould is tradition comparatively, and competition is also very fierce.The plastic products external form deviation that the plastics extrusion die of most of enterprise production is produced is bigger, and deviation range reaches ± more than the 0.5mm.The product surface effect is more undesirable, and color and luster is gloomy, even tangible aberration occurs or shrink vestige, has had a strong impact on the presentation quality of goods, can't improve the market competitiveness of goods.The analysis reason is: the conventional plastic extrusion die all is the vacuum suction mode that the pin hole of employing adds air chamber; Cooling water channel is processed with vacuumizing with pin hole dislocation intersection; Formation can coefficient vacuum suction system and but shaping system of water-cooled, with moulding shaping plastic goods.But traditional production method exists certain problem, and we know vacuum suction and cooling and shaping, and the two must work simultaneously.Principle is through the vacuum suction ability air of plastic products of extruding and shaping mould inwall to be found time; Like this under atmospheric effect; Plastic products will fit tightly on the inwall of shaping mould; In the extrusion of material, cooling system can be taken away the high temperature plastics material temperature of extruding continuously, with plastic products cooling and shaping under the restriction of the inner die cavity of shaping mould.What we stressed here is that vacuum suction and cooling and shaping must work simultaneously, and whole vacuum suction and cooling and shaping ability have only been considered in designing and producing of conventional plastic extrusion die, have but ignored the key of first section shaping mould import.General traditional moulds often all has only cooling effect but to ignore the cooperation of vacuum suction ability at this position, be after the distance of entering from die orifice about 30mm, just to begin plastics materials is carried out vacuum suction basically.So just lost the best opportunity of plastic products being carried out surface treatment and profile control, the plastic products quality of production also can decline to a great extent.
The (3) summary of the invention: the purpose of the utility model is exactly that will to solve the product surface effect of existing plastics extrusioning shaping die production undesirable; Color and luster is gloomy; Even tangible aberration occurs or shrink vestige; Have a strong impact on the problem of the presentation quality of goods, a kind of minute surface light plastics extrusioning shaping mould is provided.
The concrete scheme of the utility model is: improve to existing plastics extrusioning shaping mould; It has the main body mould that some laminates are formed; Main body mould disposes cover plate and base plate up and down, offers die cavity in the main body mould, and in the die body that cover plate, main body mould, base plate are formed, is provided with vacuum suction system and cooling and shaping system; It is characterized in that: inlet one end in main body mould disposes two bright plate of symmetric arrangement up and down; The bright plate middle inside offers groove for vacuumizing air chamber, also offers in the bright plate along long cooling water channel to layout, and cooling water channel and vacuum room's staggered floor are arranged; The said air chamber that vacuumizes is communicated with the concentrated air chamber in the vacuum suction system, and said cooling water channel one end is communicated with the concentrated tank in the cooling and shaping system, and the logical bright plate of the other end is outside.
Vacuumize the width of air chamber width described in the utility model on the bright plate greater than die cavity.
Bright plate described in the utility model is to adopt bolt and alignment pin to be contained in main body mould inlet end.
The arrival end of main body mould described in the utility model has low groove, and bright plate is to be inlaid in the groove.
The improvement of the utility model has realized first section common raising and effect simultaneously of going into the vacuum suction and the cooling and shaping ability at die orifice place of shaping mould.When high-temperature fusion plastics materials one got into the utility model die orifice, the vacuum suction system of die orifice bright plate in time was adsorbed on shaping mould die orifice place with material, and the cooling and shaping system carries out chilling processing by force with the high temperature plastics material simultaneously.Under the effect of extruding of extruder; Plastics materials and shaping mould inwall are accurate fits and the generation friction; Under function of friction, the high polishing surface of shaping mould inwall will rub the plastic products outer surface bright as minute surface, level and smooth as polishing processing.Simultaneously; Because the vacuum suction effect of the very first time; The high temperature plastics material very first time of extruding is adsorbed in the interior die cavity of shaping mould of accurate processing, has limited the free shrink and the distortion of plastics materials, thereby has improved the profile extrusion molding precision of plastic extrusion products.
The utility model is simple in structure, and is easy to use, and the shaped article surface quality is good, can make the surface of plastic products light extruded, level and smooth like minute surface, the deviation of appearance and size can be controlled in ± 0.1mm in.
