[0017] Working principle: When using this utility model, the fixed mold 2 is installed by aligning the four sets of insert pieces 5 of the fixed mold 2 with the insert slots 11 of the first side plate 7 and inserting them to the bottom; the first hydraulic cylinder 21 is activated, and its output end pushes the first connecting plate 19, which drives the transverse sliding rod 9 to move along the transverse sliding groove 8. The groove 10 of the transverse sliding rod 9 disengages from the boss 14, thereby pushing the longitudinal sliding rod 13 to move along the longitudinal sliding groove 12 until the longitudinal sliding rod 13 is inserted into the locking hole 6 of the insert piece 5, thus completing the locking of the fixed mold 2. The first hydraulic cylinder 21 is then closed, and the first spring 18 is in a compressed state. Installation of movable mold 3: Insert the lifting plate 24 and locking plate 28 inside the connecting box 4 into the connecting groove 22 on one side of the movable mold 3. Start the servo motor 30. Its power end drives the threaded rod 26 to rotate forward through the coupling. Since the upper and lower threads of the threaded rod 26 rotate in opposite directions, the two sets of lifting plates 24 move synchronously in opposite directions along the second guide rod 25, causing the locking plate 28 to be engaged in the locking groove 23 of the movable mold 3. Turn off the servo motor 30 to complete the fixation of the movable mold 3 and the connecting box 4. Overall debugging: Start the second hydraulic cylinder 32, and its output end pushes the connecting box 4 to move along the sliding rod 36 towards the fixed mold 2 until the positioning rod 33 of the fixed mold 2 is inserted into the positioning hole 34 of the movable mold 3, and the mold is completely closed. Check whether the injection channel is unobstructed and whether the push rod 38 is coaxial with the push hole 42. After confirming that there are no errors, the assembly is completed. The injection molding machine is turned on, and the plastic granules are heated and melted. The molten plastic liquid is injected into the cavity after the fixed mold 2 and the movable mold 3 are closed through the injection channel of the first side plate 7. The injection pressure is maintained. After the plastic liquid in the cavity cools and solidifies, the second hydraulic cylinder 32 is started. Its output end drives the connecting box 4 and the movable mold 3 to reset away from the fixed mold 2 along the guide sliding rod 36. When the movable mold 3 moves to the point where the second connecting plate 39 contacts the mounting rod 41, the mounting rod 41 blocks the second connecting plate 39 from moving further, while the movable mold 3 continues to reset. At this time, the second spring 40 is compressed, and the push rod 38 moves along the push hole 42 towards the cavity, pushing the molded plastic part out of the cavity of the movable mold 3. The plastic part falls naturally to the receiving device.
