As possibility; Said break-in transmission mechanism comprises first bevel gear of being fixed in the said rotating shaft and second bevel gear that is engaged with; Through being connected with a joggle of first bevel gear and second bevel gear, will be the rotation of second axis that intersects with first axle around the rotation transmission of first axle.
As another possibility, said break-in transmission mechanism comprises the worm gear that is fixed in the said rotating shaft and the worm screw that is engaged with, and through being connected with a joggle of worm gear and worm screw, will be the rotation with crossing second axis of first axle around the rotation transmission of axis.
Specifically, said mould fixed mechanism comprises a base and mould is fixed in the connecting bolt of base, thereby can the mould of different product replacedly be connected on the base through connecting bolt, and said base is fixed in said second bevel gear surface.
Said vinyl machine also comprises variable-speed controller, so that the velocity of rotation of mould is regulated.
Said mould comprises backform, bed die and mold closing mechanism, and the position that is connected of backform and bed die is provided with charging aperture and the blast pipe that is communicated with dies cavity and atmosphere.
Vinyl machine of the present invention adopts twin shaft interlock mode, and mould at the uniform velocity rotates around crossing diaxon simultaneously, can make the raw material in the mould mobile according to the shape of spinning of die cavity wall in the mould, to reach the purpose that evenly is paved with die cavity in the whole mould.

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 through first belt driver (belt pulley 111, belt 112, belt pulley 113).Through gearbox next joint pulley speed that slows down, and change transmission direction.
Being fixed with first bevel gear, 118, the second bevel gears 119 in the rotating shaft 117 is connected with a joggle in first bevel gear 118.Second bevel gear 119 and first bevel gear 118 constitute the break-in transmission mechanism, and first bevel gear 118 is followed rotating shaft 117 changes second axis that intersects with first axle into around the rotation of first axle rotation.In this example, second axis is the center line of second bevel gear 118, and itself and first axle intersect vertically.
The upper bottom surface of second bevel gear 119 is fixed with base 120, and mould 121 is connected and fixed on base 120 through bolt.
Fig. 2 has showed vinyl machine from another angle.Like Fig. 1, shown in Figure 2, mould 121 is in open mode, and it comprises backform, bed die and both are connected fixing mold closing mechanism etc.As shown in Figure 3, the connecting portion of backform and bed die is provided with charging aperture 122 and blast pipe 123, and charging aperture 122 is communicated with dies cavity and atmosphere with blast pipe 123.
Motor 110 is opened after belt 112 drives gearbox 114 and is carried out constant speed; Drive rotating shaft 117 (first axle) rotation by belt 115 after the constant speed around the axle center; Rotating shaft is rotated first bevel gear 118 is rotated; Through turning to of second bevel gear that being engaged with drive base and on mould be rotated counterclockwise, thereby the rotation that reaches around the first axle and second axis links.
Make a kind of ball of warding off with crust and interior material, its operating procedure is following:
(1) gets up charging aperture and blast pipe shutoff.Lacquer in the mould inner wall spray mould release mould injects the crust raw material.Send into the baking oven heating to vinyl machine behind the matched moulds.The frequency conversion rotary speed is 2800-3100 rev/min.Its duty is as shown in Figure 4.Liquefied mixture is along with mould 360 degree rotations are spread very thin one deck cortex, gel forming after 5-10 minute at the dies cavity wall surface equably.
(2) as shown in Figure 5, mould is rotated to and the horizontal plane vertical angle, blast pipe 123 and charging aperture 122 are made progress, unplug two exhaust stopples and secondary feeds stopple, under the mold closing state, carry out the material feeding second time (interior material).Shutoff mould material hole after the material feeding, the inactive state that keeps charging aperture to make progress.Chemical reaction takes place in raw material in mould, produce bubble, forms foam ring and constantly upwards assembles around die cavity wall, and gas broke and discharges to steam vent rapidly when bubble contacted with die wall.
(3) as shown in Figure 6, semi-finished product are taken out in die sinking.And as shown in Figure 7, fill out the sprue of warding off the ball surface.The products obtained therefrom section is as shown in Figure 8.
