The working principle is as follows: as shown in fig. 1-2 and fig. 4, the general working process of the device is that the plastic particle material in the raw material tank 7 enters into the top material cylinder 10, then the material cylinder 10 is driven by the movable circular plate 6 to rotate to the vicinity of the nozzle guide pipe 4, the hot melted material can enter into the cavity between the movable mold 3 and the fixed mold 2 through the nozzle guide pipe 4, then the material cylinder 10 continues to rotate, after the water spray rod 22 sprays water for cleaning, the material cylinder rotates to the hot air pipe 25, after drying, the material cylinder rotates to the lower part of the raw material tank 7, thereby completing the four processes of the material cylinder 10, and the four used material cylinders 10 can complete the four processes in an intermittent cycle, thereby ensuring the continuity of plastic part processing and cleaning of the material cylinders 10.

The detailed working steps of the device are as follows:

firstly, as shown in fig. 2-3, the user can connect the oil filling pipe 13 to the hot oil supply device, the specific temperature of the hot oil should be comprehensively calculated according to the melting temperature of the plastic part raw material and the heat loss during the transportation, which are not described in detail in the prior art, the hot oil enters the channel in the cross bar 9 through the oil filling pipe 13, enters the cavity 92 through the oil inlet pipe 91, is discharged into the inner pipe 94 from the oil outlet pipe 93 after flowing in the cavity 92, enters the outer ring 96 through the communicating pipe 95 after reaching the left end of the inner pipe 94, and then returns to the hot oil supply device from the oil discharge pipe 14, and the hot oil heats the whole barrel 10 when flowing in the cavity 92, thereby facilitating the subsequent melting and heat preservation of the material by the barrel 10;

the method comprises the following steps: as shown in fig. 1-2 and 4-5, firstly one of the material cylinders 10 is located below the material cylinder 7, the second motor 17 operates to drive the connecting rod 16 to move up and down through the gear 162 and the rack 161, when the connecting rod 16 moves upwards, the top plate 15 at the top end of the connecting rod correspondingly contacts with the bottom end of the material cylinder 10 and lifts the material cylinder 10 upwards, the material cylinder 10 is driven to slide in the mounting ring 12, the material discharge pipe 8 at the bottom end of the material cylinder 7 penetrates into the block 101, the block 101 correspondingly slides towards the block groove 102, the bottom end of the material discharge pipe 8 is ensured to enter the material cylinder 10, the material is heated and melted by the hot oil after entering the material cylinder 10, after a certain time, the second motor 17 drives the gear 162 to rotate reversely, so that the top plate 15 and the material discharge cylinder 10 which has been connected with the material are moved to the initial state, and the material discharge pipe 8 is separated from the material cylinder 10, the blocking blocks 101 can be gathered together again under the resilience action of the first spring 103, so that the sealing effect is achieved;

step two: as shown in fig. 4 and fig. 6, the operation of the first motor 26 will drive the cross bar 9 and the movable circular plate 6 to rotate in the frame, since the oil filling pipe 13 and the outer ring 96 are both connected with the bearing of the cross bar 9, the whole rotation of the cross bar 9 will not affect the normal circulation of the hot oil, after the rotation, the charging barrel 10 containing the molten material will be transferred to the nozzle guide pipe 4, the first electric push rod 18 will drive the vertical plate 19 to move towards the charging barrel 10, the first push rod 20 will drive the charging barrel 10 to move towards the nozzle guide pipe 4, at this time, the guide pipe will gradually push the block 101 to the side along the inclined surface of the block 101 until the nozzle guide pipe 4 and the molten material inside the charging barrel 10 are communicated, at this time, the first electric push rod 18 will drive the vertical plate 19 to move continuously, the first push rod 20 and the charging barrel 10 can not move continuously under the block of the mounting ring 12, therefore, the vertical plate 19 drives the pushing rod 202 to move in the charging barrel 10 at this time, so as to push the material pushing plate 104 to move synchronously in the charging barrel 10, thereby achieving the purpose of extruding the material to flow from the charging barrel 10 to the nozzle guide pipe 4, and enabling the material to normally enter the nozzle and the mold cavity from the charging barrel 10;

step three: after the charging barrel 10 finishes receiving and melting and conveying the molten material, the charging barrel 10 will continue to rotate 90 degrees along with the movable circular plate 6 until the charging barrel 10 can be positioned right above the hot water pipe 21, when another charging barrel 10 on the same central line with the charging barrel 10 enters step one, the charging barrel 10 will correspondingly enter step three, the upward movement of the connecting rod 16 will not only drive the top plate 15 to move upward, but also drive the water spraying rod 22 to move upward synchronously, until the water spraying rod 22 pushes the block 101 to extend into the charging barrel 10, the hot water in the hot water pipe 21 will correspondingly enter the water spraying rod 22 and be sprayed from the water outlet 221 on the water spraying rod 22 to the inner wall part of the charging barrel 10 stained with the toner, because of the staying time of the toner, the washing standard can be achieved by directly using the high-temperature hot water, without using pp material again, and the design of the conical convex strip 222, when the plugging block 101 is attached to the water spray rod 22, the cleaned water flow can still flow out along the inclined surface of the inner surface of the plugging block 101 and the gap between the conical convex strips 222, so that the adverse effect of the subsequent process caused by water residue is avoided;

step four: after cleaning, the second motor 17 is used to move the connecting rod 16 and the water spraying rod 22 downwards again, the charging barrel 10 is rotated to the vicinity of the hot air pipe 25 together with the movable circular plate 6, the second electric push rod 23 correspondingly operates, the second push plate 24 pushes the charging barrel 10 to move towards the hot air pipe 25 until the hot air pipe 25 with the nozzle at the top end can enter the charging barrel 10, the inner wall of the charging barrel 10 is further cleaned in an air blowing mode, and therefore the charging barrel 10 can normally follow the rotation of the movable circular plate 6 and enter the first step again for repeated use.

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.
