Further, annotate material mechanism and include two piston bushes 4, the equal fixed mounting of two piston bushes 4 is on the inner wall of support frame 13, slidable mounting has the second piston board in two piston bushes 4, second piston board lower surface is connected with movable rod 7, movable rod 7 extends to 4 bottoms of piston bushes and the cover is equipped with first stopper 6, 7 outer wall covers of movable rod between first stopper 6 and the piston bush 4 are equipped with spring 18, the intercommunication has first connecting pipe between the die cavity in two piston bushes 4 and the shaping die cavity 23, install the inside first check valve of flow direction shaping die cavity 23 in the first connecting pipe.

When the screw 12 rotates to drive the connecting rod 25 to move upwards, and the connecting rod 25 contacts with the movable rod 7 and continues to move upwards, the interior of the piston sleeve 4 is in a compressed state, and the raw material can enter the molding die cavity 23 through the first connecting pipe.

Further, two raw material heating boxes 9 are fixed on the upper surface of the base plate 10, a second connecting pipe is connected between the two raw material heating boxes 9 and the two piston sleeves 4, and a second one-way valve flowing into the piston sleeves 4 is installed in the second connecting pipe.

When the screw 12 rotates and drives the connecting rod 25 to move downwards, the connecting rod 25 is separated from the movable rod 7, the movable rod 7 moves downwards under the action of the spring 18, so that the interior of the piston sleeve 4 is in a negative pressure state, and at the moment, the raw material of the raw material heating box 9 can enter the piston sleeve 4 through the second connecting pipe, so that the injection molding of the next process is facilitated.

Further, stop gear includes two stop collars 2 and two gag lever posts 21, and 2 fixed mounting of two stop collars are on the outer wall of erection column 22, and two gag lever posts 21 slidable mounting are in the bottom of mount 1, and 2 inside upwards extensions of gag lever post 21 top is passed the gag lever post, and gag lever post 21 bottom is connected with and is used for gag lever post 21 gliding drive mechanism from top to bottom.

Before the operation, the limiting rod 21 is inserted into the limiting sleeve 2 and extends upwards for a certain distance, the mounting column 22 is in a limiting and fixing state at the moment, when the screw 12 is rotated manually, the core inserting and die assembling process can be completed, when the limiting rod 21 is just separated from the limiting sleeve 2, the mounting column 22 loses the limiting effect and is released from fixing, and when the screw 12 is rotated continuously, the circular plate 28, the mounting column 22 on the upper portion of the circular plate and the forming die cavity 23 can be driven to rotate, so that the material injection and the integral centrifugal rotation of the forming die cavity 23 are realized.

Further, drive mechanism includes two racks 17, and two racks 17 fixed connection all install tooth 5 at the upper surface of diaphragm 8, and two gears 19 are installed through the fixed strip rotation in mount 1 bottom, and the meshing transmission between tooth 5, rack 17 and the gear 19.

The rack 17 on the transverse plate 8 moves upwards, and due to the meshing effect of the rack 17, the gear 19 and the teeth 5, when the rack 17 moves upwards, the limiting rod 21 can move downwards, and similarly, when the rack 17 on the transverse plate 8 moves downwards, the limiting rod 21 moves upwards.

The working principle is as follows: when the centrifugal automatic forming die for plastic processing is used, firstly, an injection molding raw material is poured into a raw material heating box 9, the raw material is quickly melted by the heating action of the raw material heating box 9, because the limiting rod 21 is inserted into the limiting sleeve 2 and extends upwards for a certain distance before the raw material heating box starts to work, the mounting column 22 is in a limiting and fixing state at the moment, and then the screw 12 is manually rotated, on one hand, the screw 12 rotates to drive the circular plate 28 to rotate, and because of the arrangement of the spiral groove, the limiting action of the V-shaped groove 30 and the movable block 31 in the mounting column 22 is matched with the V-shaped arrangement of the V-shaped groove 30, when the screw 12 drives the circular plate 28 to rotate, the two vertical rods 32 can move upwards while moving towards the middle, and the core inserting die assembly process can be completed by matching with the arranged core rod 29;

on the other hand, due to the threaded connection between the screw 12 and the rod sleeve 24, in cooperation with the limit installation of the second limit block 15 and the limit groove 14, when the screw 12 rotates, the limit groove 14 can be driven to move upwards in the second limit block 15, at this time, the rack 17 on the transverse plate 8 is driven to move upwards, due to the meshing action of the rack 17, the gear 19 and the teeth 5, when the rack 17 moves upwards, the limit rod 21 can move downwards, when the forming die cavity 23 completes die assembly, the limit rod 21 just breaks away from the limit sleeve 2, at this time, the mounting column 22 loses the limit function, fixation is released, when the screw 12 continues to rotate, on one hand, the circular plate 28 and the mounting column 22 and the forming die cavity 23 on the upper portion can be driven to rotate, and simultaneously, when the screw 12 rotates to drive the connecting rod 25 to move upwards, when the connecting rod 25 contacts with the movable rod 7 and continues to move upwards, the interior of the piston sleeve 4 can be in a compressed state, the raw material can enter the forming die cavity 23 through the first connecting pipe, in the process, the forming die cavity 23 is driven to integrally rotate centrifugally by injecting the material at the same time, and the raw material can be filled to each corner in the die cavity through the centrifugal action;

because the formed product is adhered to the surface of the core rod 29 during forming, after the product is formed, the screw rod 12 is rotated reversely, at this time, the limiting rod 21 is not inserted into the limiting sleeve 2, when the screw rod 12 drives the circular plate 28 to rotate, the mounting post 22 and the forming die cavity 23 thereon can be further driven to rotate, due to the fixing effect of the core rod 29, when the forming die cavity 23 drives the formed product to rotate, the core rod 29 and the formed product can be quickly separated, manual knocking is avoided, then, the screw rod 12 is continuously rotated, the limiting rod 21 is lifted and inserted into the limiting sleeve 2, so that the mounting post 22 can be in a limiting fixed state, at this time, the forming die cavity 23 can move in the opposite direction and simultaneously move downwards by rotating the screw rod 12 in the reverse direction, and die opening and die stripping can be realized;

through the suction mechanism who sets up, when screw rod 12 rotated and drives 24 upward movements of pole cover, can further drive connecting plate 16 upward movements, at this moment, make cooling tank 20 inside be in compression state, when diaphragm 8 constantly upward movement, can impress the inside coolant liquid of cooling tank 20 inside shaping die cavity 23 inside, can further improve product shaping speed, when screw rod 12 reverses, and when driving diaphragm 8 downward movement, connecting plate 16 downward movement this moment, cooling tank 20 inside is in the negative pressure state this moment, the coolant liquid alright flow back to inside cooling tank 20.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
