Detailed description of the invention:
The shaping mould structure of a kind of compressed air as shown in the figure, thermoplastic plastic plate is first fixed on mould to be heated to softening temperature by the present invention, then the air in die cavity is taken away, it is shaping that pressure by air makes sheet material be close in die cavity, deviates from plastic part after cooling by compressed air in mould.Be provided with type cutter (9), after product is shaping, can be excised by unnecessary plastics on mould, heating plate (2) is as a part for mould structure in addition, and heating plate (2) plastic plate (12) is heated simultaneously.Adopt this formed in mould advantage to be that molding cycle is short, plastic part quality is good.The mould structure that a kind of compressed air is shaping, its technical process is: be illustrated in figure 1 die sinking situation, Figure 2 shows that matched moulds situation, after matched moulds, plastic plate (12) is heated, now in die cavity, pass into micro-compressed air, make plastic plate (12) can be heated and improve heat transfer efficiency, heating plate place (2) are in exhaust condition [as Suo Shi first arrow (13)] simultaneously; Figure 3 shows that completed state, after plastic plate (12) heating, stop sending into micro-compressed air in die cavity (10), and by passing into the preheated air [as Suo Shi 3rd arrow (15)] that pressure is 0.5-0.8Mpa above mould, plastic plate (12) is fitted on die cavity (10) inner surface shaping under pressure.Figure 4 shows that shaping after state, product is in die cavity (10) after cooling and shaping, and heating plate (2) declines a bit of distance, excises unnecessary plastics.It is the state ejecting plastic part by compressed air shown in Fig. 5.Below in conjunction with accompanying drawing, the operating principle of this mould is described in detail, known as shown in Figure 6, electrically heated rod (1) is provided with in heating plate (2), compressed air makes plastic plate (12) die cavity (10) in shaping through hot air chamber (3) through the airport (5) on plate by compressed air hose (11), and the clout of plastic plate (12) cuts off by type cutter (9).During shaping work, first be that the mould manufactured is arranged on special equipment, after connecting compressed air hose, mould is opened, input plastic plate (12), matched moulds after in mould is input at plastic plate (12), after matched moulds, plastic plate (12) is heated, in this course, the compressed air [as Suo Shi second arrow (14)] of trace is passed in die cavity (10), make plastic plate (12) that heating can be obtained and improve heat-transfer effect, heating plate (2) is in and discharges air condition [as Suo Shi first arrow (13)] simultaneously, when after plastic plate (12) heating, stop the micro-compressed air of input in die cavity (10), at this moment pass into by the compressed air hose (1) above mould the preheated air that pressure is 0.5-0.8Mpa, under the pressure effect of preheated air, plastic plate (12) is the shape of product to the interior mold cavity surface assembly of die cavity (10), after being shaped to product shape, product is cooling and shaping in die cavity (10), after product cooling and shaping, at this moment heating plate (2) and panel (4) decline and collide with the type cutter (9) be arranged on base plate (6), so the power that panel (4) and type cutter (9) are collided is plastics unnecessary for plastic plate (12) excision (as shown in Figure 4), after product cooling and shaping and excision Unneeded plastic, when product ejects, pass into compressed air from breather pipe (7) the interior mold cavity surface of product from die cavity (10) is deviate from, after product is separated with die cavity (10), at this moment compressed air pushes the precalculated position [as Suo Shi 5th arrow (17)] outside mould from mould side product.This mould structure is simple, die cost is low, meets the condition of molding of large thin-wall goods, and the product molding cycle is short, and production efficiency is high, and quality of item is graceful, saves a large amount of production cost.
