[0027] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] According to an embodiment of the utility model, a molding device for plastic products is provided.

[0029] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-9 As shown, a molding device for plastic products according to an embodiment of the utility model includes a workbench 1, a collecting box 2 is interspersed at the bottom end of the workbench 1, a molding mechanism 3 and an injection molding mechanism 4 are sequentially arranged at the top end of the workbench 1 in a direction away from the collecting box 2, and the molding mechanism 3 and the injection molding mechanism 4 are connected by a vortex tube 5.

[0030] With the aid of the above-mentioned technical scheme of the utility model, the utility model not only realizes the efficient production of plastic products through the coordinated arrangement of the molding mechanism 3, the injection molding mechanism 4 and the vortex tube 5, but also reduces the energy consumption of the independent heating and cooling steps in the traditional production, thereby ensuring the efficient use of energy and reducing the production cost of plastics.

[0031] In one embodiment, for the above-mentioned molding mechanism 3, the molding mechanism 3 includes a molding box 301 arranged at the top of the workbench 1, and the molding box 301 is provided with an electric telescopic rod 302, a mold mechanism 303 and a mold cover 304 in sequence along the direction close to the injection molding mechanism 4. The mold mechanism 303 is interspersed with an ejector mechanism 305, and the mold mechanism 303 is provided with a mold groove 306 at one end away from the electric telescopic rod 302; the ejector mechanism 305 includes a pressing column 30501 interspersed at the other end of the mold mechanism 303, and the pressing column 30501 is provided with a moving column 30502 at one end away from the electric telescopic rod 302, and the moving column 30502 is provided with a limiting column 30503 at one end close to the vortex tube 5. A pin 30504 is arranged at one end of the limiting column 30503 away from the electric telescopic rod 302, and a spring 30505 is arranged on the outside of the pin 30504. A slot 30506 matching with the pressing column 30501, the moving column 30502, the limiting column 30503 and the spring 30505 is provided inside the pin mechanism 305. The contacting ends of the pressing column 30501, the moving column 30502 and the limiting column 30503 are all inclined surfaces; under the action of the contraction of the electric telescopic rod 302, the pressing column 30501 can be squeezed, thereby pushing the pin 30504 to eject the cooled and formed plastic from the mold groove 306, thereby realizing the rapid demolding of the formed plastic and improving the production efficiency of plastic products.

[0032] In addition, it should be noted that the above-mentioned electric telescopic rod 302 is composed of an electric motor, a reduction gear set, a telescopic rod body, a door positioning sensor, a limit switch, a control unit and a power supply. The working principle of the electric telescopic rod 302 is to convert the rotational motion into a linear driving force through the reduction gear set, thereby pushing the pipe sections inside the telescopic rod body to extend or retract sequentially. The composition and working principle of the electric telescopic rod 302 are existing technologies and will not be elaborated in detail here.

[0033] Working principle of the molding mechanism 3: After the plastic product in the mold groove 306 is cooled and formed, the mold mechanism 303 is driven to move away from the mold cover 304 by the action of the electric telescopic rod 302 contracting, until the electric telescopic rod 302 squeezes the pressing column 30501, so that the pressing column 30501 squeezes the moving column 30502, so that the moving column 30502 moves in the direction of the limiting column 30503, and squeezes the limiting column 30503 and the ejector pin 30504 to move in the direction of the mold groove 306, so that the ejector pin 30504 pushes the cooled and formed plastic out of the mold groove The mold mechanism 303 is pushed toward the mold cover 304 by the extension of the electric telescopic rod 302 until it cannot move, so that the mold mechanism 303 forms a closed space close to the mold cover 304, so that the injection molding mechanism 4 can inject molten plastic into the mold mechanism 303, and at the same time, the compressed spring 30505 restores the ejector mechanism 305 to its original state under the elastic action.

[0034] In one embodiment, for the above-mentioned vortex tube 5, the vortex tube 5 includes an air pipe 501 inserted and arranged at one end of the molding mechanism 3 close to the injection molding mechanism 4, and the interior of the air pipe 501 is sequentially provided with a separation pipe 502, a turbine pipe 503, a threaded pipe 504 and a hot gas end regulating valve 505 in a direction away from the molding mechanism 3. An air intake duct 506 is inserted and arranged on the outer side of the air pipe 501 close to the turbine pipe 503, and an air compressor 507 is arranged at one end of the air intake duct 506 away from the air pipe 501; a plurality of turbine blade slots 508 are opened at one end of the turbine pipe 503 away from the molding mechanism 3; a stopper 509 is arranged inside the hot gas end regulating valve 505; the plurality of turbine blade slots 508 are evenly arranged and circular. The air compressor 507 is used to pass high-pressure air through the turbine tube 503, so that the air can flow through the turbine tube 503 to form a high-speed rotating airflow, and generate hot air under the action of the hot air end regulating valve 505, which is passed into the injection molding mechanism 4 to heat and melt the plastic. At the same time, cold air is generated through the separation tube 502, and is passed into the molding mechanism 3 to cool the molded plastic, thereby reducing the energy consumption of independent heating and cooling steps in traditional production, improving resource utilization, and reducing the production cost of plastics.

[0035] In addition, it should be noted that the above-mentioned air compressor 507 is composed of an electric motor, a piston, a cylinder, a crankshaft, a connecting rod, an end cover, a cooling system, a lubrication system, and a control system. The working principle of the air compressor 507 is that the crankshaft rotates to drive the connecting rod, causing the piston to reciprocate in the cylinder, and the air is compressed. At this time, the exhaust valve opens, and the compressed air is discharged into the air storage tank. The composition and working principle of the air compressor 507 are existing technologies and will not be elaborated on here.

[0036] The working principle of the vortex tube 5 is as follows: under the action of high-pressure air introduced by the air compressor 507, air can flow through the turbine tube 503, thereby forming a high-speed rotating airflow, and under the action of the block 509 to block the airflow, the air pipe 501 is passed into one end of the injection molding mechanism 4 to separate the hot airflow, and then passed into the injection molding mechanism 4 to heat and melt the plastic. At the same time, the blocking effect of the separation tube 502 makes the other end of the air pipe 501 generate cold air, which is passed into the molding mechanism 3 to cool the molded plastic, thereby reducing the energy consumption of the independent heating and cooling steps in traditional production, improving resource utilization, and reducing the production cost of plastics.

[0037] In one embodiment, for the above-mentioned injection molding mechanism 4, the injection molding mechanism 4 includes a heating tube 401 arranged at one end of the molding mechanism 3, and the interior of the heating tube 401 is sequentially provided with an injection molding tube 402 and a threaded column 403 along the circumferential center direction, and a motor 404 is provided at the end of the threaded column 403 away from the molding mechanism 3; a feeding tank 405 is interspersed on the outer side of the injection molding tube 402 close to the motor 404; the threaded column 403 can be driven to rotate under the rotation of the output shaft of the motor 404, thereby driving the molten plastic in the injection molding tube 402 to be transmitted to the molding mechanism 3.

[0038] The working principle of the injection molding mechanism 4 is as follows: by adding plastic raw materials into the feeding tank 405, and under the action of hot air passing from the vortex tube 5 to the heating tube 401, the plastic raw materials are melted, and under the rotation of the output shaft of the motor 404, the threaded column 403 is driven to rotate, thereby driving the molten plastic in the injection molding tube 402 to be transferred to the molding mechanism 3 for cooling and molding of the plastic.

[0039] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0040] In actual application, the operator adds plastic raw materials to the injection molding mechanism 4, and at the same time, introduces hot air into the injection molding mechanism 4 through the vortex tube 5 to heat and melt the plastic. At the same time, introduces cold air into the molding mechanism 3 to cool the molded plastic, and ejects the molded plastic to fall into the collection box 2. This not only realizes the efficient production of plastic products, but also reduces the energy consumption of independent heating and cooling steps in traditional production, ensures efficient use of energy, and thus reduces the production cost of plastics.

[0041] In summary, with the aid of the above technical solution of the utility model, through the coordinated arrangement of the molding mechanism 3, the injection molding mechanism 4 and the vortex tube 5, not only the efficient production of plastic products is achieved, but also the energy consumption of the independent heating and cooling steps in the traditional production is reduced, the efficient utilization of energy is ensured, and the production cost of plastics is reduced; by setting the ejector mechanism 305, the pressing column 30501 can be squeezed under the action of the contraction of the electric telescopic rod 302, so as to push the ejector 30504 to eject the cooled and molded plastic from the mold groove 306, thereby realizing the rapid removal of the molded plastic. The vortex tube 5 is provided so that the air can flow through the turbine tube 503 under the action of the high-pressure air introduced by the air compressor 507, thereby forming a high-speed rotating airflow, and generating hot air under the action of the hot air end regulating valve 505, which is introduced into the injection molding mechanism 4 to heat and melt the plastic. At the same time, cold air is generated through the action of the separation tube 502, which is introduced into the molding mechanism 3 to cool the molded plastic, thereby reducing the energy consumption of the independent heating and cooling steps in the traditional production, improving the resource utilization rate, and reducing the production cost of the plastic.
