Further, the water cooler 20 and the circulating water pump 21 are fixedly arranged on one side of the fixed die 12, the water cooler 20 is connected with the circulating water pump 21 through a connecting pipe 2001, the water cooling pipe 22 surrounds the inner concave die periphery side in the fixed die 12, two ends of the water cooling pipe 22 are respectively connected with the water cooler 20 and the circulating water pump 21 through circulating water pipes 2201, so that the water cooler 20 is used for providing a water cooling source, water in the water cooling pipe 22 is pumped back through the circulating water pump 21, water circulation between the water cooler 20 and the water cooling pipe 22 is realized, cold water is introduced into the water cooling pipe 22, and the fixed die 12 is cooled.

The working principle is as follows: when using, injection moulding device reaches the condition of moulding plastics after, through controller control, start step motor 802, step motor 802 output shaft rotates, and drive through pivot 901 and rotate mounting bracket 9 and rotate 8 tops in the fixed bolster, make and rotate mounting bracket 9 and be in the horizontality, rotate the end of moulding plastics 7 that end 1's injection moulding nozzle 7 is aimed at to injection moulding on the cover half 12 of mounting bracket 9 one end promptly, and promote through second hydraulic push rod 502 among thrust unit 5 and mould plastics end 1 and remove to shaping end 2, utilize end 1 bottom of moulding plastics through slide rail 6 in brace table 3 sliding connection, under thrust unit 5's promotion, end 1 of moulding plastics can slide on brace table 3, and will mould plastics nozzle 7 and stretch into in the interface 1201 of moulding plastics.

Then, the electric push rod 803 on the supporting plate 801 on one side of the fixing support 8 is used for pushing the limit push rod 804, so that the limit push rod 804 extends out of the top of the fixing support 8 and is located above the rotating installation frame 9 in a horizontal state, the rotating installation frame 9 is fixed, and the phenomenon that the rotating installation frame 9 shakes during injection molding is avoided.

Then, a first hydraulic push rod 16 is started, a linkage plate 15 is pushed by the first hydraulic push rod 16 fixed to the middle of the surface of the rotary mounting frame 9, a movable die 13 is pushed through a connecting rod 14, the movable die 13 can slide on the fixed slide rod 11, the first hydraulic push rod 16 is controlled to contract or stretch, the movable die 13 is attached to the fixed die 12 until the movable die 13 and the fixed die 12 are completely attached, then the controller 301 is used for controlling injection molding equipment to perform injection molding, cold water is injected into a water cooling pipe 22 in the fixed die 12 by starting a water cooling machine 20 and a circulating water pump 21, and the injection molding part is cooled in an accelerated manner.

And then after injection molding is finished and injection molding is stopped, the second hydraulic push rod 502 is contracted to pull the injection molding end 1 to leave the molding end 2, so that the injection molding nozzle 7 leaves the injection molding interface 1201, the electric push rod 803 is controlled to contract, the limit push rod 804 is withdrawn, the stepping motor 802 is started again to drive the rotating mounting frame 9 to continue rotating for 180 degrees, the combined movable mold 13 and the fixed mold 12 rotate to the other end, the water cooling pipe 22 continuously carries out water cooling on the injection molding part and the fixed mold 12 in the process, and the time for waiting for cooling is saved.

After one end of injection molding is far away from the injection molding end 1, the previous injection molding work is repeated again, when the first hydraulic push rod 16 pushes the linkage plate 15, so that the movable mold 13 close to the injection molding end 1 is merged towards the fixed mold 12, the movable mold 13 at the other end of the mounting frame 9 starts to be separated from the fixed mold 12, meanwhile, the fixed ejector pins 17 are fixed on the side surface of the mounting vertical plate 10, when the movable mold 13 moves towards the mounting vertical plate 10, the fixed ejector pins 17 prop against the movable ejector pins 19 through the springs 18, when the movable ejector pins are firstly propped, the compression degree of the springs 18 is small, the elasticity of the movable ejector pins 19 is small, the movable ejector pins 19 are not easy to prop, the movable ejector pins 13 gradually approach the mounting vertical plate 10, the elasticity is slowly strengthened, and then the movable ejector pins 19 move forwards, so that an injection molding part is ejected.

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.
