[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a vacuum forming machine with rapid demolding effect, including a device base plate 1, a vacuum forming mold 2 fixedly installed on the top of the device base plate 1, a vacuum pump 3 fixedly installed on one side of the vacuum forming mold 2, and a cooling adjustment mechanism 4 provided on the top of the device base plate 1.

[0025] The cooling adjustment mechanism 4 includes a first slide groove 401. The first slide groove 401 is formed on one side of the top of the device base plate 1. A first motor 402 is fixedly installed on one inner wall of the first slide groove 401. A protective stop 403 is fixedly installed on the output shaft end of the first motor 402. A threaded rod 404 is fixedly installed on one side of the protective stop 403. A support block 405 is fixedly installed on the inner wall of the first slide groove 401 on the other side away from the first motor 402. The side of the threaded rod 404 away from the protective stop 403 is rotatably connected to one side of the support block 405. A positioning screw block 406 is threadedly connected to the outer end of the threaded rod 404. A second slide groove 407 is formed on the other side of the top of the device base plate 1 away from the first slide groove 401. A support guide rod 408 is fixedly installed inside the second slide groove 407. A support slider 409 is movably sleeved on the outer end of the support guide rod 408. A mounting support rod 410 is fixedly installed on the top of the positioning screw block 406 and the top of the support slider 409. A protective housing 411 is fixedly installed in the middle of the support rod 410. A mounting bracket 412 is fixedly installed inside the protective housing 411. A second motor 413 is fixedly installed in the middle of the mounting bracket 412. A fan blade 414 is fixedly installed at the output shaft end of the second motor 413. A semiconductor cooling chip 415 is fixedly installed inside the protective housing 411. The heating end of one side of the semiconductor cooling chip 415 extends to the outer end of the protective housing 411. An air outlet mesh 416 is opened at the bottom end of the protective housing 411. When the first motor 402 is started, it drives the threaded rod 404 to rotate, causing the positioning screw block 406 to move linearly on the threaded rod 404, thus moving the protective housing 411. When the second motor 413 and the semiconductor cooling chip 415 are started, the second motor 413 drives the fan blade 414 to rotate at high speed. The low temperature of the cooling end of the semiconductor cooling chip 415 combines with the airflow generated by the fan blade 414, and the cold air is blown out through the air outlet mesh 416 at the bottom end of the protective housing 411.

[0026] An L-shaped bracket 5 is fixedly installed at the top of the base plate 1 of the device. A hydraulic cylinder 6 is fixedly installed at the top of the L-shaped bracket 5. An adjusting push rod 7 is fixedly installed at the output end of the hydraulic cylinder 6. The adjusting push rod 7 extends to the bottom end of the L-shaped bracket 5. A connecting plate 8 is fixedly installed at the bottom end of the adjusting push rod 7. A heating plate 9 is fixedly installed at the bottom end of the connecting plate 8. A heating wire 10 is fixedly installed inside the heating plate 9. When the hydraulic cylinder 6 is activated, the output end of the hydraulic cylinder 6 pushes the adjusting push rod 7 down. The adjusting push rod 7 drives the connecting plate 8 and the heating plate 9 to move downward.

[0027] Working principle: The plastic sheet is placed above the vacuum forming mold 2. The hydraulic cylinder 6 is activated, and its output pusher 7 descends. The pusher 7 moves the connecting plate 8 and heating plate 9 downwards, bringing the heating plate 9 closer to the plastic sheet. The heating wire 10 heats the heating plate 9, transferring heat to the plastic sheet and softening it. Then, the vacuum pump 3 is activated. The vacuum pump 3 extracts air from between the mold and the plastic sheet through the vents on the vacuum forming mold 2, creating a negative pressure environment. Under this negative pressure, the softened plastic sheet adheres to the surface of the vacuum forming mold 2, forming the desired plastic product shape. The vacuum pump 3 uses a LEMC150 model. After the plastic product is formed, rapid cooling is required for quick demolding, causing the connecting plate 8 to rise. Then, the vacuum pump 3 is activated. The first motor 402 is activated, which drives the threaded rod 404 to rotate, causing the positioning screw block 406 to move linearly on the threaded rod 404. This moves the protective housing 411, thereby moving the support slider 409 on the support guide rod 408, improving the stability of the protective housing 411. The second motor 413 and the semiconductor cooling chip 415 are then activated. The second motor 413 drives the fan blades 414 to rotate at high speed, forming an airflow inside the protective housing 411. The low temperature at the cooling end of the semiconductor cooling chip 415 combines with the airflow generated by the fan blades 414, and the cold air is blown out through the air outlet mesh 416 at the bottom of the protective housing 411. This cools the plastic products at different positions on the thermoforming mold 2, accelerates their curing speed, improves cooling efficiency, and enhances demolding efficiency.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
