[0034] refer to Figure 1 and Figure 2 The finished product cooling molding equipment for manufacturing plastic products also includes a fan 11 and a heat sink 12. The fan 11 is installed on the front of the injection molding machine 2 and the upper part of the movable mold 5. The fan 11 at the front of the injection molding machine 2 is used to dissipate the heat of the cooling water in the serpentine tube 86, and the fan 11 is installed with a heat sink 12.

[0035] Initially, the movable mold 5 is in an open mold state, and the cooling pipe 81, the hose 82, the connecting pipe 83, the bent pipe 84, the cavity 61, the straight pipe 85 and the serpentine pipe 86 are filled with an appropriate amount of cooling water. The block 1 842 does not block the upper end of the U-shaped portion 841, and the block 1 842 is in an open state. The block 2 851 blocks the left end of the serpentine pipe 86, and the block 2 851 is in a closed state.

[0036] First, cooling water is introduced into the water inlet pipe 90, and the electric slide rail 4 is controlled to drive the movable mold 5 to move leftward to close the mold. For details on the closing state, refer to Fig. 9 and Fig.10 When the left side of the movable mold 5 contacts the right side of the sliding member 7, the movable mold 5 continues to move left, and the movable mold 5 pushes the sliding member 7 to move left. The push plate 98 moves left with the sliding member 7, and the compression spring 72 is compressed. When the push plate 98 contacts the connecting plate 97, the push plate 98 pushes the connecting plate 97 to move left, driving the slider 9, the cooling nozzle 10, the thin rod 91, the piston block 92 and the sliding cylinder 95 to move left, and the return spring 96 is stretched. When the piston block 92 leaves the thick cylinder 93, the cooling water in the water inlet pipe 90 flows into the channel 32, and the cooling water then flows into the thin cylinder 94 through the thick cylinder 93.

[0037] When the push plate 98 moves to the left and blocks the right end of the channel 32, the push plate 98, the slide 7 and the movable mold 5 stop moving to the left. At this time, the cooling nozzle 10 enters the channel 32, and a cavity 51 is formed between the movable mold 5 and the fixed mold 3. The injection molding machine 2 is controlled to inject, so that the raw material is injected into the cavity 51 through the injection hole 31. When the injection molding machine 2 completes the injection, the electric slide rail 4 is controlled to drive the movable mold 5 to move to the right to open the mold. For details on the mold opening state, refer to Figure 6 and Figure 7 , the compression spring 72 is restored, driving the sliding member 7 and the push plate 98 to move rightward and reset, the push plate 98 that moves rightward will separate from the connecting plate 97, the return spring 96 is restored, driving the piston block 92, the thin rod 91, the slider 9, the sliding cylinder 95 and the cooling nozzle 10 to move rightward and reset, the cooling nozzle 10 extends from the channel 32, the reset piston block 92 will enter the thick cylinder 93, the piston block 92 squeezes the cooling water in the thick cylinder 93, so that the cooling water in the thick cylinder 93 flows to the cooling nozzle 10 through the thin cylinder 94, so that the cooling nozzle 10 can spray The cooling water is supplied to the inner surface of the finished product. For finished products such as hollow containers or cylinders, a faster cooling speed can be achieved. At the same time, the fan 11 on the movable mold 5 is controlled to blow air toward the finished product. The finished product is cooled with the cooperation of the heat sink 12. The cooling water in the cooling pipe 81 can absorb the heat of the finished product under the action of heat conduction. The cooling pipe 81 is spiral in shape, which can increase its contact area with the movable mold 5. Thus, the finished product can be cooled by the cooling nozzle 10, the fan 11 and the cooling pipe 81, with a fast cooling speed and a good cooling effect.

[0038] After absorbing heat, the cooling water in the cooling pipe 81 increases in temperature, and part of the cooling water vaporizes. The high-temperature liquid and steam in the cooling pipe 81 enter the cavity 61 through the hose 82, the connecting pipe 83 and the bent pipe 84 on the rear side. When the movable mold 5 is closed again, similarly, the annular portion 71 of the sliding member 7 will move to the left, the volume of the cavity 61 will decrease, the annular portion 71 squeezes the high-temperature liquid and steam in the cavity 61, and the pressure in the cavity 61 increases. Under the action of pressure, the block 1 842 will move upward, and the block 1 842 will block the upper end of the U-shaped portion 841. The block 1 842 is closed, and the block 2 851 will move forward. The block 2 851 no longer blocks the left end of the serpentine tube 86, and the block 2 851 is opened, so that the high-temperature liquid and steam in the cavity 61 enter the serpentine tube 86, and the serpentine tube 86 is cooled by the liquid cooling box 88. The temperature is lowered to lower the temperature of the high-temperature liquid and steam in the serpentine tube 86, and the fan 11 at the front of the injection molding machine 2 is controlled to blow air, and the cooling is assisted with the cooperation of the heat sink 12 to accelerate the cooling speed; when the movable mold 5 is opened again, the annular portion 71 of the sliding member 7 will move to the right and reset, the volume of the cavity 61 will increase, and the pressure in the cavity 61 will decrease. The block 1 842 and the block 2 851 are both reset by the reset spring 1, the block 1 842 is opened and the block 2 851 is closed. The function of the throttle valve 87 is to throttle the saturated liquid under the condensation pressure in the serpentine tube 86 to the evaporation pressure and evaporation temperature. At the same time, according to the change of load, the water flow entering the cooling tube 81 is adjusted, so that the cooling water in the serpentine tube 86 flows back to the cooling tube 81, and the cooling water in the cooling tube 81 can play a cooling role again.

[0039] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 and Fig.14 The finished product cooling and molding equipment for manufacturing plastic products also includes a tensioning mechanism, which includes a fixed frame 101, a translation block 102 and a tensioning wheel 103. The front and rear parts of the base 1 are welded with fixed frames 101, and a pair of translation blocks 102 with opposite sliding directions are slidably connected to the fixed frames 101. A return spring 2 is fixedly connected between the translation block 102 and the fixed frame 101. The translation block 102 is rotatably connected to the tensioning wheel 103. Fig.14 The two hoses 82 are respectively wound around two tensioning wheels 103 on the same side.

[0040] Initially, the second reset spring is in a stretched state. When the movable mold 5 is closed, the cooling tube 81 moves to the left along with the movable mold 5, and the second reset spring is restored, driving the two tensioning wheels 103 on the same side to move away from each other, so that the hose 82 is kept in a tensioned state under the action of the tensioning wheel 103, avoiding bending of the hose 82 and ensuring normal circulation of cooling water.
