The implementation principle of the sheath plastic dip molding machine in the embodiment of the application is as follows: the screw rod 10 is driven to rotate by the forward and reverse rotation motor 11, and the mounting frame 7 is driven by the screw rod 10 to drive the mold 8 to move from the collection box 61 to the oven 5. At this time, the coating roller 27 is driven by the first driving motor 29 to rotate the coating layer 28, and the release agent on the surface of the coating layer 28 is applied to the blocks on the lower end surface of the die 8. The mold 8 is then passed into an oven 5 for preheating.

Subsequently, the mounting frame 7 drives the mold 8 to move towards the impregnation box 42, and when the dovetail bar 14 slides into the dovetail groove 38, the guide slope 242 drives the adjusting column 241 to drive the driving rod 181 and the driving block 182 to vertically slide downwards under the interference of the side wall of the mounting block 13. Subsequently, the two mounting rings 20 are driven by the respective return springs 22 to move the locking rods 16, and the locking rods 16 are disengaged from the respective locking grooves 17, thereby unlocking the mold 8. Then, the air cylinder 12 drives the mounting block 13 to drive the dovetail strip 14 and the die 8 to vertically move downwards, and then the module on the lower end face of the die 8 enters the dip dyeing box 42. Subsequently, the molten material in the dip tank 42 covers the module on the lower end face of the mold 8, thereby realizing the dipping operation.

Then, the air cylinder 12 drives the mounting block 13 to drive the dovetail strip 14 and the die 8 to reset, the forward and reverse rotating motor 11 drives the screw rod 10 to rotate reversely, and the screw rod 10 drives the mounting frame 7 to drive the die 8 to move towards the oven 5. At this time, the guide slope 242 is disengaged from the dovetail groove 38, and then the driving block 182 is moved upward by the elastic force of the return spring 23. Subsequently, two locking bars 16 are inserted into the respective locking grooves 17 under the urging of the side walls of the driving block 182, thereby achieving the locking of the mold 8. The installation frame 7 continues to drive the mold 8 to move, the mold 8 enters the oven 5, and then the oven 5 can be used for baking the molten raw material, so that the molten raw material is formed into the sheath.

As the mounting frame 7 continues to move the mold 8, the second drive motor 35 drives the cleaning roller 33 to move the bristles 34 as the mold 8 moves over the collection box 61. The bristles 34 exert a vertically downward force on the sheath, thereby enabling the sheath to be quickly removed from the mold 8. Meanwhile, air is delivered to the nozzle 37 through the air pump 36, and then the air is sprayed out through the nozzle 37 and blows the air to the sheath, so that the temperature of the sheath is reduced. At the same time, it is also possible to blow the sheath off the mould 8 and to let the sheath fall into the collection box 61, thus achieving the collection of the sheath.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
