Description

Technical Field

[0001] This utility model relates to the technical field of injection molding cooling devices, specifically a photovoltaic injection molding cooling device for medical device production. Background Technology

[0002] In medical device manufacturing, the cooling device for injection molds is crucial because it directly affects product quality and production efficiency. For example, a method for manufacturing a high-efficiency cooling device for medical device injection molds includes components such as an operating platform, support frame, electric telescopic rod, upper mold, cooling chamber, lower mold, circulating water pump, refrigerator, and cooling pipes. This device uses the combined use of the circulating water pump and refrigerator to circulate cooling water within the mold, thereby achieving efficient cooling of the injection mold.

[0003] Currently, there are many types of injection molding cooling devices. For example, Chinese patent number CN202122392850.9 describes a cooling device for injection molds used in medical reagent kits. This patent includes an injection mold and a cooling device. The injection mold includes an upper mold and a lower mold. The top of the lower mold has a mold groove, and a molding cavity is provided within the mold groove. The molding cavity is detachably mounted on the lower mold via a connector. A spiral coil is provided within the mold groove, surrounding the outside of the molding cavity. A serpentine coil is provided on the inner bottom wall of the mold groove, located at the bottom of the molding cavity. This solution uses cooling... The combination of the cooling device, tee pipe, spiral coil, and serpentine coil can cool the molding cavity, thereby accelerating the cooling and molding of the product inside the molding cavity. In addition, the molding cavity can be detachably installed on the lower mold through the connector, so the molding cavity is easy to disassemble and assemble. After the molding cavity is disassembled, the spiral coil and serpentine coil in the mold groove can be taken out for cleaning or replacement, thus ensuring the cooling effect. However, in actual use, since the cooling points of this device are all located on the left and right sides and the bottom of the mold box, while the top cannot perform any cooling work, this makes the product prone to defects after the mold is opened.

[0009] Furthermore, the two ports of the cooling pipe are connected to the water supply hose and the return hose, respectively.

[0010] Furthermore, both the cooling box and the upper sealing plate are provided with insertion slots adapted to the cooling pipes.

[0011] Furthermore, the upper fixing plate is fixedly connected to the right side of the upper sealing plate by two fixing bolts, and the lower fixing plate is fixedly connected to the right side of the cooling box by two fixing bolts.

[0012] Furthermore, the closing mechanism includes an adjusting frame. The adjusting frame is fixedly connected to the left side of the cooling box.

[0015] 1. This photovoltaic injection molding cooling device for medical device production, through the setting of a circulating cooling mechanism and circulating refrigeration components, firstly, a water pump delivers condensate from the water tank to the refrigerator for cooling. Then, the cooled condensate flows into two water supply hoses through the manifold connecting pipe and the first T-shaped tee, and then through the water supply hoses connected to the cooling pipes, allowing the condensate to enter the cooling box and the cooling pipes in the upper sealing plate respectively. At this time, the upper and lower mold boxes can be cooled simultaneously. Finally, through the connection of the cooling pipes and the return water hose, the condensate flows back to the return water hose when it reaches the end point in the cooling pipe. At the same time, because the joint of the two return water hoses is equipped with a second T-shaped tee, the condensate on the upper and lower sides will meet and return to the water tank through the manifold return water pipe, and so on. Thus, this mechanism can not only ensure cooling efficiency, but also maintain a consistent cooling rate between the upper and lower parts, making it highly practical. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-3In this embodiment, a photovoltaic injection molding cooling device for medical device production includes a cooling box 1. A cover mechanism 2 is provided on the left side of the cooling box 1. An upper sealing plate 3 adapted to the cooling box 1 is provided on the cover mechanism 2. A circulating cooling component 4 is provided on the right side of the cooling box 1. The circulating cooling component 4 is composed of a base plate 6, a cooler 7, a water pressure pump 8, and a water tank 9. A circulating cooling mechanism 5 extending into the cooling box 1 and the upper sealing plate 3 is provided on the left side of the circulating cooling component 4.

[0022] The circulating cooling mechanism 5 includes a fixed plate 501, a first T-shaped tee 505, and a second T-shaped tee 508. The right side of both the cooling box 1 and the upper sealing plate 3 is connected to a fixed plate 501. Each fixed plate 501 has two fixing bolts 502. A cooling pipe 503 is installed on the left side of each fixed plate 501. A water supply hose 504 and a return hose 507 are installed on the right side of both fixed plates 501. The two ends of the cooling pipe 503 are connected to the water supply hose 504 and the return hose 507, respectively. The two water supply hoses 504 are fixedly connected by a first T-shaped tee 505. A manifold connecting pipe 506 is fixedly connected to the right end of the first T-shaped tee 505, with the end of the manifold connecting pipe 506 away from the first T-shaped tee 505 fixedly connected to the water outlet of the chiller 7. The two return water hoses 507 are fixedly connected by a second T-shaped tee 508. A manifold return water pipe 509 is fixedly connected to the front end of the second T-shaped tee 508, with the manifold return water pipe 509 away from the second T-shaped tee 508. One end of the tube 508 is fixedly connected to the water tank 9. Firstly, the water pump 8 delivers the condensate from the water tank 9 to the cooler 7 for cooling. Then, the cooled condensate flows through the manifold 506 and the first T-shaped tee 505 into two water hoses 504. These hoses are connected to the cooling pipes 503, allowing the condensate to enter the cooling tank 1 and the cooling pipes 503 in the upper sealing plate 3 respectively. At this point, both the upper and lower mold boxes can simultaneously cool. The cooling process is completed via a cooling pipe 503 connected to a return water hose 507. This allows the condensate to flow back into the return water hose 507 after reaching the end point of the cooling pipe 503. Simultaneously, the two return water hoses 507 are connected by a second T-shaped tee 508, allowing the condensate from the upper and lower sides to meet and return to the water tank 9 via a converging return water pipe 509. This process is repeated continuously, ensuring not only efficient cooling but also consistent cooling rates at both ends, making it highly practical.

[0023] In the implementation of the case, both the cooling box 1 and the upper sealing plate 3 are provided with insertion slots that are compatible with the cooling pipe 503. At the same time, the upper fixing plate 501 is fixedly connected to the right side of the upper sealing plate 3 by two fixing bolts 502, and the lower fixing plate 501 is fixedly connected to the right side of the cooling box 1 by two fixing bolts 502. This design allows the mechanism to be freely disassembled and assembled as needed, which is convenient for maintenance and storage, and has strong practicality.

[0024] In the implementation of the case, the closing mechanism 2 includes an adjusting frame 201. The adjusting frame 201 is fixedly connected to the left side of the cooling box 1. A reciprocating servo motor 202 is fixedly installed on the top of the adjusting frame 201. Two bearings 203 are fixedly installed inside the adjusting frame 201. A threaded rod 204 connected to the output end of the reciprocating servo motor 202 is fixedly connected to the inner wall of the two bearings 203. A threaded sleeve 205 is threadedly connected to the outer wall of the threaded rod 204. A limiting guide plate 206 connected to the inner wall of the adjusting frame 201 is provided on the left side of the threaded sleeve 205. A connecting plate 207 connected to the left side of the upper sealing plate 3 is fixedly connected to the right side of the threaded sleeve 205. This design can effectively ensure the sealing between the upper sealing plate 3 and the cooling box 1, while also saving manpower and having strong practicality.

[0025] In the implementation of the case, a lower mold box 101 is provided inside the cooling box 1 and above the lower insertion slot, and an upper mold box 301 adapted to the lower mold box 101 is provided below the upper sealing plate 3. This design can further improve the sealing performance of the device and avoid product defects caused by incomplete cooling.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) First, the water pump 8 will transport the condensate in the water tank 9 to the refrigerator 7 for cooling;

[0028] 2) The cooled condensate can then flow into the two water hoses 504 through the combination of the manifold 506 and the first T-shaped tee 505;

[0029] 3) The water supply hose 504 is connected to the cooling pipe 503, so that the condensate can enter the cooling tank 1 and the cooling pipe 503 in the upper sealing plate 3 respectively;

[0030] 4) Finally, the cooling pipe 503 is connected to the return water hose 507, so that when the condensate flows to the end in the cooling pipe 503, it will flow back to the return water hose 507, and so on.

[0031] In summary, this photovoltaic injection molding cooling device for medical device production, through the setting of a circulating cooling mechanism 5 and a circulating refrigeration component 4, firstly, the water pump 8 delivers the condensate from the water tank 9 to the cooler 7 for cooling. Then, the cooled condensate flows into two water supply hoses 504 through the cooperation of the manifold connecting pipe 506 and the first T-shaped tee 505. The water supply hoses 504 are connected to the cooling pipes 503, allowing the condensate to enter the cooling tank 1 and the cooling pipes 503 in the upper sealing plate 3 respectively. At this time, the upper and lower mold boxes can be cooled simultaneously. Finally, the condensate is cooled through the cooling pipes 503 and the return hose. 507 are interconnected, allowing condensate to flow back into the return hose 507 when it reaches the end point in the cooling pipe 503. Simultaneously, because the two return hoses 507 are connected by a second T-shaped tee 508, the condensate from the upper and lower sides meets and returns to the water tank 9 through the confluence return pipe 509, repeating this process. This mechanism not only ensures cooling efficiency but also maintains a consistent cooling rate from top to bottom, making it highly practical. It solves the problem that the cooling points of the device are all located on the left and right sides and below the mold box, while the upper part cannot perform any cooling work, which leads to defects in the product after mold opening.
