[0040] The working process of the present invention is as follows:

[0041] The cooling mold 3 is in the open mold state through the mold clamping mechanism 2. When the product on the mandrel of the injection blow hollow molding machine rotates to the demolding station, the translation mechanism 1 moves forward towards the demolding station, and at the same time drives the mold clamping mechanism 2 forward. After reaching the position, the product on the mandrel of the injection blow hollow molding machine descends and falls into the cooling mold 3. At the same time, the mold clamping mechanism 2 performs a mold clamping action. After the mold clamping is in place, it is locked by the cylinder for a certain period of time. The product is further cooled and shaped in the cooling mold 3. After completion, the horizontal mechanism 1 drives the mold clamping mechanism 2 to retreat together, so that the product is separated from the mandrel and retreats to the final position. Then the product clamping mechanism 4 moves horizontally from the side, so that each bottle picking head is aligned with the center of the product. Then the horizontal mechanism 1 advances a certain distance, so that the bottle picking head enters the interior of the product. Then the mold clamping mechanism 2 opens the mold, and the product clamping mechanism 4 rises, drives the product to move horizontally to the original position, and rotates 90°, so that the product falls into the bottle separating mechanism 6. The bottle separating mechanism 6 drives the product to move downwards and places the product on the conveyor line 5. The product is moved to the designated position through the conveyor line 5.

[0042] The translation motor 1-18 drives the motor synchronous pulley 1-17 to rotate, drives the lead screw synchronous pulley 1-15 through the synchronous belt 1-16, and further drives the lead screw 1-19 to rotate. At the same time, the lead screw nut 1-12 and the horizontal nut seat 1-27 move forward, and the slider 1-28 drives the horizontal support plate 1-11 and the lower mold base 2-6 to move forward. After reaching the position, the mold clamping cylinder 2-24 acts, and the upper mold base 2-22 is clamped under the action of the mold clamping cylinder 2-24. The upper mold 3-1 of the cooling mold moves towards the lower mold 3-2 of the cooling mold. After the mold clamping is in place, the cylinder maintains a certain pressure. After the product cooling and shaping is completed, the translation motor 1-18 rotates in the reverse direction to make the cooling mold retreat. After retreating to the position, the mold clamping cylinder 2-24 acts to drive the upper mold base 2-22 to open the mold, and the upper mold 3-1 of the cooling mold moves upward, and the mold opens.

[0043] The clamping translation servo motor 4-24 drives the clamping translation reducer 4-23, the clamping translation driving wheel 4-28, and the clamping translation synchronous belt 4-15 to rotate, drives the clamping translation slider top plate 4-22 to move horizontally through the clamping translation slider 4-16, and makes the bottle picking suction head 4-8 move forward. After reaching the position, the rodless cavity of the lifting cylinder 4-7 intakes air, and the bottle picking suction head 4-8 rises a certain distance. The clamping translation servo motor 4-24 rotates in the reverse direction to make the bottle picking suction head 4-8 retreat to the original position. The rodless cavity of the lifting cylinder 4-7 intakes air again and rises to the position. The rotating cylinder 4-1 intakes air to make the bottle picking suction head 4-8 rotate 90°. When the product falls into the bottle sleeve, the rotating cylinder 4-1 rotates in the reverse direction to return to the original position, and the rodless cavity of the lifting cylinder 4-7 intakes air, and the bottle picking suction head 4-8 descends to the original position.

[0044] After the product falls into the bottle sleeve 6-4, the rodless cavity of the bottle separating and lifting cylinder 6-1 is filled with air, driving the bottle separating slider seat 6-6 to move downward. At the same time, the product also moves downward by a certain distance. When it moves to the switch position, the rodless cavity of the baffle cylinder 6-15 is filled with air, and the baffle 6-5 retracts. The product falls from the bottle sleeve 6-4 onto the conveyor line 5. At this time, the rod cavity of the bottle separating and lifting cylinder 6-1 is filled with air, driving the bottle separating slider seat 6-6 and the bottle sleeve 6-4, etc. to move upward to the original position. Then, the rodless cavity of the baffle cylinder 6-15 is filled with air, and the baffle 6-5 extends to block directly below the bottle sleeve. The product is conveyed along the conveyor line 5 to the designated position.
