Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1 and Figure 2, the embodiment of the present invention mainly comprises core 1, die cavity (not shown), thimble (not shown), ejector retainner plate 3, thimble fixed head 4, mould pin 2, lower compound plate 5, air sparging piece 6.
Particularly, core 1 is positioned at die cavity below, and thimble is fixed on thimble fixed head 4, ejector retainner plate 3 and thimble fixed head 4 is stacked is integrated, mould pin 2 is connected between core 1 and lower compound plate 5, and ejector retainner plate 3 and thimble fixed head 4 can be located between core 1 and lower compound plate 5 up or down.For another example shown in 3-Fig. 7, air sparging piece 6 is cylindricality, is provided with along its length air duct 60 in inside, and outer face is provided with the air intake 600 being communicated with air duct 60, and inner face is provided with an outstanding valve 63 for injecting pressure-air to die cavity.The side of core 1 is provided with groove 10, and air sparging piece 6 embeds in groove 10, and 63 of valves stretch in die cavity.
As Fig. 2, the present embodiment is for the production of the working of plastics 9 shown in Fig. 8, Fig. 9, and can produce two simultaneously.Every corresponding two air sparging pieces 6 of product, the valve 63 of every two air sparging pieces 6 is corresponding with the two ends, edge of working of plastics 9, makes its edge be hollow structure, therefore, has four grooves 10 around core 1.
For stable air injection block 6 and after working of plastics 9 injection mouldings complete, be convenient to the demoulding, the present embodiment also comprises briquetting 7, slide block 8 and inclination guide pillar 81.Wherein, briquetting 7 is elongated, is two, embeds in groove 10, and is pressed on respectively air sparging piece 6 upper surface both sides.The two side of groove 10 inside is stepped simultaneously, and air sparging piece 6 is positioned at bottom, and briquetting 7 parts are pressed and put on air sparging piece 6, and another part is pressed and put on the upper strata step of groove 10 sidewalls.Slide block 8 is fixed on die cavity, and its upper surface is provided with two screws 800, can be fixed in by this screw 800 the lower surface lateral margin of die cavity.In groove 10, slide block 8 is positioned at the centre of two briquettings 7 and is pressed on the upper surface of air sparging piece 6.Air sparging piece 6 is provided with an outward-dipping circular hole 610, and slide block 8 is provided with consistent with circular hole 610 incline directions and mutual corresponding limiting hole 80, and the upper end of inclination guide pillar 81 is arranged in limiting hole 80, and insert in circular hole 610 lower end of inclination guide pillar 81.In addition, also have deep hole (not shown) corresponding with circular hole 610 and that incline direction is consistent on the bottom surface of groove 10, insert the lower end of being convenient to guide pillar 81.
