The mold is drilled with small holes for vacuum adsorption of heated hard plastic sheets to form blister products. During the production process of blister molds, high temperatures will form inside. The continuous rise in temperature will affect the molding efficiency of the mold products, and most of the processing is cooled by a water pool, which will cause secondary pollution to the product quality.

The patent transports heat into the inside of the heat pipe through the copper plate, and the heat pipe can transport heat into the inside of the heat exchange plate, which can provide preliminary cooling during the working process.

In order to improve work efficiency, it is necessary to actively cool down, and a cooling mechanism is arranged on the front of the shell 1. The cooling mechanism includes a circulating cooling pipe 3 and a water pump 5. The circulating cooling pipe 3 is fixedly installed on the inner wall of the shell 1, and the circulating cooling pipe 3 is set to be S-shaped. The circulating cooling pipe 3 is in contact with the plastic suction mold body 2. When coolant flows inside the circulating cooling pipe 3, the plastic suction mold body 2 can be quickly cooled down. The water pump 5 is fixedly installed on the right side of the shell 1, and the water pump 5 is connected to the circulating cooling pipe 3 through the delivery pipe 4. The water pump 5 provides power to circulate the coolant inside the delivery pipe 4, which is beneficial to improve the cooling effect.

[0033] Reference Figure 2 - Figure 3 The cooling mechanism also includes a cooling box 6, which is fixedly mounted on the front of the shell 1. A protective cover 61 is hinged on the top of the cooling box 6 to prevent external debris from entering the cooling box 6. A handle is fixedly connected to the top of the protective cover 61 for the convenience of the staff to open the protective cover 61. The cooling box 6 is connected to the water pump 5 through the delivery pipe 4. The water pump 5 provides power to make the coolant inside the cooling box 6 flow. The cooling mechanism also includes heat-conducting fins 8, which are fixedly mounted on the front of the cooling box 6. The heat-conducting fins 8 have good heat conduction performance. A cooling fan 7 is fixedly connected to the front of the heat-conducting fins 8. When the cooling fan 7 rotates, the airflow will flow, thereby taking away the heat of the heat-conducting fins 8, which is beneficial to improving the heat dissipation efficiency.

[0034] Reference Figure 3 - Figure 5 The cooling mechanism also includes a mounting plate 9, a slot 10 is provided on the inner wall of the cooling box 6, the mounting plate 9 is plugged into the inner wall of the slot 10, the number of mounting plates 9 is set to be multiple, and the mounting plate 9 is set to be a hollow plate. The cooling mechanism also includes a positioning rod 11, the positioning rod 11 is slidably mounted on the inner wall of the mounting plate 9, the sliding direction of the positioning rod 11 is forward and backward sliding, and an arc-shaped surface is provided at one end of the positioning rod 11 away from the center of the mounting plate 9, the positioning rod 11 is elastically connected to the inner wall of the mounting plate 9 through a spring 12, and the spring 12 is provided so that the positioning rod 11 has a tendency to move away from the center of the mounting plate 9, and a positioning groove 13 matching the positioning rod 11 is provided on the inner wall of the slot 10.

[0035] Reference Figure 5 - Figure 6The cooling mechanism also includes a guide box 14 and a heat exchange plate 15. The guide box 14 is fixedly installed on the left side of the mounting plate 9. The number of guide boxes 14 is set to be multiple. The heat exchange plate 15 is clamped on the upper and lower sides of the guide box 14. The number of heat exchange plates 15 is set to be multiple groups. A metal mesh with good heat conduction performance is arranged inside the heat exchange plate 15. By arranging multiple groups of heat exchange plates 15, the contact area between the coolant and the heat exchange plate 15 is increased, thereby improving the efficiency of heat exchange, and then improving the efficiency of cooling and cooling. The cooling mechanism also includes a rotating rod 16, and the rotating rod 16 rotates Installed on the inner wall of the heat exchange plate 15, the circumferential surface of the rotating rod 16 is fixedly connected with a control plate 18 arranged in a long strip shape, and the outer wall of the rotating rod 16 is elastically connected to the inner wall of the heat exchange plate 15 through a torsion spring 17. By setting the torsion spring 17, the control plate 18 has a torque that rotates away from the center direction of the heat exchange plate 15. The upper and lower sides of the inner wall of the guide box 14 are provided with control grooves 19 that match the control plate 18. The control plate 18 is initially inserted into the inside of the control groove 19, so that the heat exchange plate 15 is stably fixed on the upper and lower sides of the guide box 14.

[0036] Working principle: When in use, by starting the power supply of the water pump 5 and the cooling fan 7, the water pump 5 drives the coolant inside the cooling box 6 to move, and the coolant circulates through the delivery pipe 4 and the circulating cooling pipe 3. The circulating cooling pipe 3 and the blister mold body 2 are in contact for heat exchange, so as to achieve the purpose of continuously and rapidly cooling the blister mold body 2, so that the temperature of the blister mold body 2 will not continue to rise. At the same time, the cooling fan 7 drives the airflow to take away the heat of the coolant inside the cooling box 6, and further improves the cooling effect.

[0037] Open the protective cover 61 by the handle, then pull the mounting plate 9 upwards to take the mounting plate 9 out from the interior of the cooling box 6. When the mounting plate 9 moves upwards, the edge of the positioning groove 13 will squeeze the arc-shaped surface of the positioning rod 11, so the positioning rod 11 will overcome the elastic force of the spring 12 and move toward the center of the mounting plate 9. Therefore, the positioning rod 11 will not hinder the upward displacement of the mounting plate 9. At the same time, the positioning rod 11 inserted into the positioning groove 13 can improve the stability of the mounting plate 9 when it is inserted into the slot 10 and is stationary, thereby ensuring the stable heat exchange.

[0038] By rotating the rotating rod 16, the rotating rod 16 will overcome the elastic force of the torsion spring 17 and rotate toward the center of the heat exchange plate 15, thereby driving the control plate 18 to disengage from the inside of the control groove 19, and then the heat exchange plate 15 can be removed from the upper and lower sides of the guide box 14, making it convenient to clean and replace the heat exchange plate 15.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
