At this time, the lifting slider 52 will move the upper mold box 6 downward, and finally the pressing plate 61 is completely inserted into the profiling groove 41. At this time, the lower mold box 4 is in a tightly fitted state, which effectively ensures the sealing effect. Then the injection molding machine 3 is operated to inject the thermoplastic plastic slurry into the profiling groove 41 through the injection groove 62, so as to complete the injection molding production of the PCR plate in the cavity formed by the pressing plate 61 and the profiling groove 41.

[0032] Reference Figure 3 , Figure 5 , wherein the cooling mechanism includes a water-cooling groove 7, which is opened in the lower mold box 4, and a stirring rod 71 is rotatably connected in the water-cooling groove 7.

[0033] Through the arrangement of the above-mentioned structure, during the rotation of the lifting screw 51, the meshing relationship between the second bevel gear 74 and the first bevel gear 73 will cause the stirring rod 71 to rotate with the stirring impeller 72 in the water-cooling tank 7, so that the water in the water-cooling tank 7 can flow, and the water flows in various places in the water-cooling tank 7 can flow with each other, so that the water flows in various places can exchange heat with each other, avoiding the situation of uneven water flow temperature, ensuring the water cooling effect, avoiding the situation of cracking of the PCR plate caused by uneven cooling, and thus improving the production quality of the PCR plate.

[0034] Reference Figure 5-Figure 8, wherein the side wall of the lower mold box 4 is fixedly connected with a positioning plate 42, the top of the positioning plate 42 is fixedly connected with a positioning guide rod 421, the top of the positioning guide rod 421 passes through the lifting slider 52 and is fixedly connected to the bottom of the lifting platform 5; the recoil assembly includes a ventilation groove 8, the ventilation groove 8 is opened in the upper mold box 6, and both sides of the bottom of the ventilation groove 8 are provided with recoil grooves 81, a piston plate 82 is slidably connected in the recoil groove 81, a first spring 821 is fixedly connected between the bottom of the piston plate 82 and the recoil groove 81, a piston rod 822 is fixedly connected to the bottom of the piston plate 82, and a flushing hole 823 is commonly opened between the piston plate 82 and the piston rod 822; a steam groove 83 is opened in the positioning plate 42, and the steam groove 83 is communicated with the inner cavity of the water cooling groove 7, A lower air guide groove 831 is provided in the positioning guide rod 421, and a force storage groove 832 is provided in the lifting slider 52. The lower air guide groove 831 and the force storage groove 832 are movably connected, and the force storage groove 832 is connected to the ventilation groove 8 through the upper air guide groove 833, and a force storage mechanism is arranged in the force storage groove 832; the force storage mechanism includes a force storage rod 84, and a sealing slot 841 is provided in the force storage groove 832. The force storage rod 84 is slidably connected in the sealing slot 841, and the bottom end of the force storage rod 84 extends through to the bottom of the lifting slider 52 and is fixedly connected to a contact plate 842, and a second spring 843 is fixedly connected between the top of the contact plate 842 and the bottom of the lifting slider 52, and the second spring 843 is sleeved on the outer side of the force storage rod 84.

[0035] By setting the above structure, in the process of the upper mold box 6 and the lower mold box 4 being fitted together, the top of the positioning plate 42 will contact the contact plate 842, and in the process of the upper mold box 6 continuing to move downward, the contact plate 842 and the force storage rod 84 will be pushed to move upward, and the second spring 843 will be compressed, so that the force storage rod 84 is inserted into the bottom of the sealing slot 841, thereby sealing the upper air guide groove 833, and after the upper mold box 6 and the lower mold box 4 are fitted together, the lower air guide groove 831 will be in a state of being connected with the force storage groove 832; and in the injection molding process, the cooling water that is closer to the profiling groove 41 will be evaporated after absorbing the heat of the molten slurry, so that the air pressure in the water-cooling groove 7 increases, and the above-mentioned steam will enter the steam groove 83 under the action of the air pressure, and then enter the force storage groove 832 along the lower air guide groove 831. After completion, when the upper mold box 6 moves upward to reset, the force storage rod 84 will move downward under the rebound action of the second spring 843, thereby releasing the blockage of the upper air guide groove 833. At this time, the steam accumulated in the force storage groove 832 will enter the ventilation groove 8, and under the action of air pressure, push the piston plate 82 downward, so that the piston rod 822 passes through the recoil groove 81, so that the output end of the air hole 823 is connected to the outside world. At this time, the steam will be discharged along the air hole 823, thereby quickly generating a jet of air at the bottom of the pressing plate 61, giving the formed PCR plate a downward impact, effectively avoiding the PCR plate from sticking to the pressing plate 61, facilitating material removal, and improving production efficiency. In addition, the moisture in the air flow will cover the surface of the PCR plate, thereby cooling the surface of the PCR plate and improving the cooling efficiency.

[0036] Reference Figure 3-Figure 5 , wherein, an air box 75 is rotatably connected to the outer wall of the stirring rod 71, the bottom of the air box 75 is fixedly connected to the top of the processing table 1, and a guide blade 751 is fixedly connected to the outer wall of the stirring rod 71 located in the air box 75. A guide groove 752 is opened in the inner cavity of the stirring rod 71, one end of the guide groove 752 is connected to the inner cavity of the air box 75, and one end of the guide groove 752 passes through the stirring rod 71 and is connected to the outside world. The side wall of the air box 75 is fixed and connected with an air guide hose 753, the other end of the air guide hose 753 is connected to the inner cavity of the power storage groove 832, and a one-way valve is arranged in the air guide hose 753.

[0037] It should be noted that the one-way valve in the air guide hose 753 can only allow the airflow in the inflation box 75 to enter the power storage tank 832.

[0038] Through the arrangement of the above structure, the stirring rod 71 drives the guide blade 751 to rotate in the inflation box 75, so that the external airflow is sucked into the inflation box 75 along the guide groove 752, and the airflow will pass through the entire water cooling groove 7, thereby effectively reducing the temperature of the airflow, and then the airflow will enter the air guide hose 753, and after flushing the one-way valve in the air guide hose 753, it will enter the storage groove 832 along the air guide hose 753, and then continue to be discharged from the air flushing hole 823, thereby generating a cooler airflow effect on the top of the PCR plate, further improving the cooling efficiency and realizing efficient production.

[0039] Reference Figure 1-Figure 3 , wherein the transfer assembly includes a material moving screw 9, a bearing seat 91 is fixedly connected to the top of the processing table 1 and the side wall of the frame of the conveyor belt 2, the material moving screw 9 is rotatably connected between the bearing seats 91 on both sides, a material moving motor 92 is fixedly connected to the side wall of the bearing seat 91, the output shaft of the material moving motor 92 is fixedly connected to the end of the material moving screw 9, a sliding sleeve 93 is threadedly connected to the material moving screw 9, and a suction and discharge mechanism is arranged on the sliding sleeve 93, a guide slide bar 931 is fixedly connected between the bearing seats 91 on both sides, and the guide slide bar 931 passes through the side wall of the sliding sleeve 93; the material suction and discharge mechanism includes an electric telescopic rod 94, the electric telescopic rod 94 is fixed on the sliding sleeve 93, a suction plate 95 is fixedly connected to the bottom of the telescopic end of the electric telescopic rod 94, adsorption plates 951 are fixedly connected to both sides of the bottom of the adsorption plate 95, an air suction pump 952 is fixedly connected to the bottom of the adsorption plate 95, and the air suction end of the air suction pump 952 is connected to the inner cavity of the adsorption plate 951.

[0040] Through the arrangement of the above structure, after the PCR plate is cooled and shaped, the material moving motor 92 drives the material moving screw 9 to rotate, so that the adsorption plate 951 moves to the top of the PCR plate, and then the electric telescopic rod 94 is extended and retracted, so that the bottom end of the adsorption plate 951 is attached to the top of the PCR plate, and then the suction pump 952 starts to work, so that the PCR plate is fixed at the bottom of the adsorption plate 951, and then the material moving motor 92 continues to drive the material moving screw 9 to rotate, so that the sliding sleeve 93 moves the PCR plate to the conveyor belt 2. When the PCR plate moves to the top of the conveyor belt 2, the electric telescopic rod 94 first extends downward, and then the suction pump 952 stops working, so that the PCR plate is transported to the conveyor belt 2, and finally moves to the next process with the operation of the conveyor belt 2, realizing automated transportation, and effectively improving the automated production efficiency.

[0041] Reference Figure 1-Figure 8In the present invention, when in use, the lifting motor 53 is turned on to drive the lifting screw rod 51 to rotate. At this time, the lifting slider 52 will move the upper mold box 6 downward, and finally the pressing plate 61 is completely inserted into the profiling groove 41. At this time, the lower mold box 4 is in a tightly fitted state, which effectively ensures the sealing effect. Then the injection molding machine 3 is operated to inject the thermoplastic slurry into the profiling groove 41 through the injection groove 62, so as to complete the injection molding production of the PCR plate in the cavity formed by the pressing plate 61 and the profiling groove 41; and when the slurry enters the injection cavity, it will be affected by the water in the water cooling tank 7. The flow cooling effect allows for rapid cooling and shaping, thereby effectively increasing production efficiency. Furthermore, during the rotation of the lifting screw 51, the meshing relationship between the second bevel gear 74 and the first bevel gear 73 causes the stirring rod 71 to rotate with the stirring impeller 72 in the water cooling tank 7, thereby causing the water in the water cooling tank 7 to flow, and the water flows at various locations in the water cooling tank 7 to flow with each other, thereby allowing the water flows at various locations to exchange heat with each other, avoiding uneven water flow temperature, ensuring the water cooling effect, and avoiding cracking of the PCR plate caused by uneven cooling, thereby improving the production quality of the PCR plate.

[0042] When the upper mold box 6 and the lower mold box 4 are in contact with each other, the top of the positioning plate 42 will contact the contact plate 842, and when the upper mold box 6 continues to move downward, the contact plate 842 and the force storage rod 84 will be pushed upward, and the second spring 843 will be compressed, so that the force storage rod 84 is inserted into the bottom of the sealing slot 841, thereby sealing the upper air guide groove 833, and after the upper mold box 6 and the lower mold box 4 are in contact with each other, the lower air guide groove 831 will be in a state of communication with the force storage groove 832; and during the injection molding process, the cooling water that is closer to the profiling groove 41 will evaporate after absorbing the heat of the molten slurry, so that the air pressure in the water-cooling groove 7 increases, and the steam generated above will enter the steam groove 83 under the action of the air pressure, and then enter the force storage groove 832 along the lower air guide groove 831. When the injection molding is completed, the upper mold box 6 and the lower mold box 4 are in contact with each other. When the mold box 6 moves upward to reset, the force storage rod 84 will move downward under the rebound action of the second spring 843, thereby releasing the blockage of the upper air guide groove 833. At this time, the steam accumulated in the force storage groove 832 will enter the ventilation groove 8, and under the action of air pressure, push the piston plate 82 downward, so that the piston rod 822 passes through the recoil groove 81, so that the output end of the air hole 823 is connected to the outside world. At this time, the steam will be discharged along the air hole 823, thereby quickly generating a jet of air at the bottom of the pressing plate 61, giving the formed PCR plate a downward impact, effectively avoiding the PCR plate from sticking to the pressing plate 61, facilitating material removal, and improving production efficiency. In addition, the moisture in the air flow will cover the surface of the PCR plate, thereby cooling the surface of the PCR plate and improving the cooling efficiency. Subsequently, when the accumulated steam is exhausted, the lower air guide groove 831 and the power storage groove 832 will be disconnected, and the stirring rod 71 will drive the guide blade 751 to rotate in the inflation box 75, so that the external airflow is sucked into the inflation box 75 along the guide groove 752, and the airflow will pass through the entire water cooling groove 7, thereby effectively reducing the temperature of the airflow, and then the airflow will enter the air guide hose 753, and after opening the one-way valve in the air guide hose 753, it will enter the power storage groove 832 along the air guide hose 753, and then continue to be discharged from the air hole 823, thereby generating a cooler airflow effect on the top of the PCR plate, further improving the cooling efficiency and achieving efficient production.

[0043] After the PCR plate is cooled and shaped, the material moving motor 92 drives the material moving screw 9 to rotate, so that the adsorption plate 951 moves to the top of the PCR plate, and then the electric telescopic rod 94 is extended and retracted, so that the bottom end of the adsorption plate 951 is attached to the top of the PCR plate, and then the suction pump 952 starts to work, so that the PCR plate is fixed at the bottom of the adsorption plate 951, and then the material moving motor 92 continues to drive the material moving screw 9 to rotate, so that the sliding sleeve 93 moves the PCR plate to the conveyor belt 2. When the PCR plate moves to the top of the conveyor belt 2, the electric telescopic rod 94 first extends downward, and then the suction pump 952 stops working, so that the PCR plate is transported to the conveyor belt 2, and finally moves to the next process as the conveyor belt 2 runs, realizing automated transportation, effectively improving automated production efficiency.
