Description

Technical Field

[0001] This utility model relates to the technical field of oven-type rotational molding machines, and in particular to a cooling station for an oven-type rotational molding machine. Background Technology

[0002] An oven-type rotational molding machine is a heating device used in rotational molding processes. Its core feature is that the rotational molding mold is placed in a heating chamber similar to an oven for heating, so that the plastic raw material melts in the mold and adheres evenly to the inner wall of the mold, thereby forming a hollow plastic product. After the product is made using the oven-type rotational molding machine, it needs to be transferred to a cooling station to cool down.

[0003] However, the cooling station of existing oven-type rotational molding machines relies solely on natural cooling or simple air cooling during operation. The heat exchange efficiency between the cooling medium and the rotational molding mold is limited, resulting in excessively long cooling times. This not only reduces production efficiency but may also affect the production cycle and capacity of rotational molded products. Especially in large-scale production, slow cooling speed can become a bottleneck in the entire production process. To address these issues, we propose a cooling station design for oven-type rotational molding machines. Utility Model Content

[0004] The purpose of this invention is to provide a cooling station for an oven-type rotational molding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cooling station of an oven-type rotational molding machine includes a base plate, four support blocks are fixedly connected to the outer surface of the base plate, a cooling box is fixedly connected to the outer surface of the four support blocks, two air-cooling mechanisms are provided on the outer surface of the cooling box, a liquid-cooling mechanism is provided inside the cooling box, and a placement mechanism is provided inside the cooling box.

[0006] In a further embodiment, the air-cooling mechanism includes a vent and a mounting bracket, and a drive motor is fixedly mounted on the outer surface of the mounting bracket.

[0007] In a further embodiment, a rotating rod is fixedly connected to the output end of the drive motor, and a plurality of fan blades are fixedly connected to the outer surface of the rotating rod, with each fan blade located inside a ventilation opening.

[0008] In a further embodiment, the liquid cooling mechanism includes a liquid storage tank, and a liquid pump is fixedly installed on the outer surface of the liquid storage tank.

[0009] In a further embodiment, the output end of the infusion pump is fixedly connected to a return pipe, one end of which is fixedly connected to the interior of the storage tank, and a cooling coil is fixedly connected to the outer surface of the storage tank. One end of the cooling coil passes through the cooling tank and extends to the outside of the cooling tank, and the other end of the cooling coil is fixedly connected to the input end of the infusion pump.

[0010] In a further embodiment, the placement mechanism includes two first slides and two second slides, with a placement plate slidably connected to the interior of the two first slides and the interior of the two second slides.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device significantly improves the heat exchange efficiency between the cooling medium (air) and the rotational molding mold through the synergistic effect of the air-cooling mechanism and the liquid-cooling mechanism. The air-cooling mechanism directly accelerates the airflow on the mold surface, while the liquid-cooling mechanism circulates low-temperature coolant through cooling coils. The combination of the two achieves dual cooling, effectively reducing the mold temperature and significantly shortening the cooling time. The mounting mechanism supports flexible adjustment of the mounting plate position or replacement with mounting plates of different specifications to adapt to rotational molding molds of different sizes and shapes, enhancing the versatility and applicability of the equipment and solving the problem of low cooling efficiency caused by traditional natural cooling or single air cooling.

[0019] 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.

[0020] Please see Figure 1-4In this utility model, a cooling station of an oven-type rotational molding machine includes a base plate 1. Four support blocks 2 are fixedly connected to the outer surface of the base plate 1. A cooling box 3 is fixedly connected to the outer surface of the four support blocks 2. Two air-cooling mechanisms 4 are provided on the outer surface of the cooling box 3. The air-cooling mechanism 4 includes a vent 401 and a mounting frame 402. A drive motor 403 is fixedly installed on the outer surface of the mounting frame 402. A rotating rod 404 is fixedly connected to the output end of the drive motor 403. Several fan blades 405 are fixedly connected to the outer surface of the rotating rod 404. Each fan blade 405 is located inside the vent 401. When the fan blades 405 are located inside the vent 401, they draw in external cold air into the cooling box 3 when rotating. At the same time, the fan blades 405 at the other end draw out the air inside the cooling box 3, thereby expelling the internal hot air and accelerating the airflow on the surface of the rotational molding mold.

[0021] The cooling tank 3 is equipped with a liquid cooling mechanism 5, which includes a liquid storage tank 501. A liquid pump 502 is fixedly installed on the outer surface of the liquid storage tank 501. The output end of the liquid pump 502 is fixedly connected to a return pipe 503. One end of the return pipe 503 is fixedly connected to the inside of the liquid storage tank 501. A cooling coil 504 is fixedly connected to the outer surface of the liquid storage tank 501. One end of the cooling coil 504 passes through the cooling tank 3 and extends to the outside of the cooling tank 3. One end of the cooling coil 504 is fixedly connected to the input end of the liquid pump 502. The surface of the cooling coil 504 is covered with thermally conductive adhesive. The cooling pipe contacts the rotational molding mold. Heat is conducted to the cooling pipe through the thermally conductive adhesive. The coolant carries away the heat and returns to the coolant storage tank through the coolant recovery device and recovery pipe.

[0022] The cooling box 3 is equipped with a placement mechanism 6, which includes two first slides 601 and two second slides 602. The interior of the two first slides 601 and the interior of the two second slides 602 are slidably connected to a placement plate 603. The placement plate 603 can be easily moved by the staff through the first slides 601 and the second slides 602, so that the rotational molding mold above the placement plate 603 can make stable contact with the thermally conductive adhesive on the surface of the cooling coil 504.

[0023] The working principle of this utility model is as follows: In use, firstly, the base plate 1 is fixed in a suitable position through the mounting holes. The heated and plasticized rotational molding mold is placed on the mounting plate 603. The mounting plate 603 is slidably pushed into the cooling box 3 through the first sliding groove 601 and the second sliding groove 602 on both sides, completing the fixing and positioning of the mold and making it contact the cooling coil 504, ensuring that the mold is within the coverage of air cooling and liquid cooling. Then, the drive motor 403 and the infusion pump 502 are started through the controller. The drive motor 403 starts, driving the rotating rod 404 to rotate. The multiple fan blades 405 on the rotating rod 404 rotate at high speed, forcibly delivering high-speed airflow into the cooling box 3 through the ventilation port 401. The high-speed airflow directly blows on the mold surface, accelerating the airflow on the mold surface. The cooling coil 504 removes heat from the mold surface, achieving initial cooling. The infusion pump 502 starts, drawing coolant from the cooling coil 504 and returning it to the storage tank 501. The cooling coil 504 is distributed around the inside of the cooling tank 3. As the low-temperature coolant flows through the coil, it absorbs the heat emitted by the mold. The coolant, after its temperature rises, returns to the storage tank 501 through the return pipe 503, completing the cycle. The storage tank 501 can maintain the low temperature of the coolant through an external refrigeration system, ensuring continuous and efficient heat absorption capacity. When the mold temperature reaches the process requirements, the drive motor 403 and the infusion pump 502 stop running. The mounting plate 603 slides out of the cooling tank 3 through the slide groove. The operator takes out the cooled mold and proceeds to the next production stage.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
