The specific embodiment
As shown in Figure 1, be vinyl machine of the present invention, it comprises support, mould, mould fixed mechanism, drive system, transmission device.
Drive system mainly comprises motor 110.Gearbox 114 is transmitted in motor output shaft by the first belt driver (belt pulley 111, belt 112, belt pulley 113).Slowing down by gearbox, next saves pulley speed, and changes transmission direction.
In rotating shaft 117, being fixed with the first bevel gear 118, the second bevel gears 119 is connected with a joggle in the first bevel gear 118.The second bevel gear 119 and the first bevel gear 118 form direction-changing drive mechanism, the first bevel gear 118 are followed to rotating shaft 117 and changes into around the rotation of first axle the rotation of second axis crossing with first axle.In this example, the second axis is the center line of the second bevel gear 118, and itself and first axle intersect vertically.
The upper bottom surface of the second bevel gear 119 is fixed with base 120, and mould 121 is bolted and is fixed on base 120.
Fig. 2 has shown vinyl machine from another angle.As shown in Figure 1 and Figure 2, mould 121 is in open mode, and it comprises backform, bed die and mold closing mechanism that both are connected and fixed etc.As shown in Figure 3, be provided with charging aperture 122 and blast pipe 123 on the connecting portion of backform and bed die, charging aperture 122 is communicated with dies cavity and atmosphere with blast pipe 123.
Motor 110 drives gearbox 114 to carry out constant speed through belt 112 after opening, after constant speed, drive rotating shaft 117 (first axle) rotation around axle center by belt 115, rotating shaft is rotated the first bevel gear 118 is rotated, through turning to of the second bevel gear of being engaged with drive base and on mould be rotated counterclockwise, be connected thereby reach around the rotation of first axle and the second axis.
Make a kind of ball of warding off with crust and interior material, its operating procedure is as follows:
(1) charging aperture and blast pipe shutoff are got up.Paint in mould inner wall spray mould release mould, injects crust raw material.After matched moulds, vinyl machine is sent into baking oven heating.Frequency conversion rotary speed is 2800-3100 rev/min.Its duty as shown in Figure 4.Liquefied mixture is along with mould 360 degree rotations are spread thin layer cortex at dies cavity wall surface, gel forming after 5-10 minute equably.
(2) as shown in Figure 5, by mould rotation to horizontal plane vertical angle, make blast pipe 123 and charging aperture 122 upwards, unplug two exhaust stopples and secondary feeds stopple, under mold closing state, carry out material feeding for the second time (Inner material).Shutoff mould material hole after material feeding, keeps charging aperture inactive state upwards.There is chemical reaction in raw material, produce bubble in mould, forms foam ring and constantly upwards assemble around die cavity wall, and when bubble contacts with die wall, gas breaks and discharges to steam vent rapidly.
(3) as shown in Figure 6, die sinking, takes out semi-finished product.And as shown in Figure 7, fill out the sprue of warding off ball surface.Products obtained therefrom section as shown in Figure 8.
