Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a blister box mold structure. Background Technology

[0002] Currently, molds are used in industrial production to create various molds and tools for obtaining desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. Vacuum forming molds refer to the molds used in vacuum forming production. When using a vacuum forming mold, the flat vacuum forming plastic is heated until it softens, and then vacuum-adhered to the surface of the mold to cool and solidify.

[0003] However, existing thermoforming molds have poor heat dissipation. Because the heat of the thermoforming plastic is absorbed by the mold, when the heat on the mold cannot be dissipated in time, the heat accumulates gradually during use, resulting in inconsistent molding quality of the subsequently formed thermoformed products, leading to rework or scrap. Furthermore, the disassembly and disassembly of thermoforming molds on the machine is cumbersome and inconvenient, failing to meet user needs and limiting its applicability.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0037] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0038] A blister box mold structure includes a base 10, a mold body 20, a cooling mechanism 30, and an ejection mechanism 40; wherein: the mold body 20 is detachably mounted on the upper end of the base 10;

[0039] The cooling mechanism 30 includes a cooling pipe 31, a liquid storage tank 32, and a liquid delivery device 33. The cooling pipe 31 is arranged in a serpentine shape on the base 10. The base 10 has a positioning groove 111 for positioning the cooling pipe. The cooling pipe 31 is placed on the positioning groove 111 and sandwiched between the mold body 20 and the base 10. The outer side of the base 10 has two first clearance openings 112 that communicate with the positioning groove. The two ends of the cooling pipe 31 extend out of the base 10 from the two first clearance openings 112 and are respectively connected to the liquid delivery device 33 and the liquid storage tank 32. The liquid delivery device 33 and the liquid storage tank 32 are connected by a pipe 34.

[0040] The ejection mechanism 40 includes a rod 41 and a driving device (not shown in the figure). The rod 41 is movably mounted on the base 10 and is located on one side of the positioning groove. The driving device is connected to the rod so that the rod pushes the mold body upward and separates it from the base. Specifically, the base has a cavity with an upper opening, and the positioning groove is located on the inner end face of the cavity. The lower end of the mold body extends into the cavity. In this way, through the design of each component, the heat of the mold body is absorbed and dissipated by the cooling pipe, and the coolant is circulated on the cooling pipe by the liquid delivery device, thereby improving the heat dissipation effect of the mold body and ensuring the stable and consistent quality of the thermoformed product. With the setting of the ejection mechanism, the mold body is pushed upward out of the base, so as to facilitate the disassembly and replacement of the mold body, thereby meeting the thermoforming needs of different types of molds and satisfying the user's needs. It has good usability and a wide range of applications.

[0041] In this embodiment, a heat-conducting plate 12 is provided between the cooling pipe 31 and the mold body 20. The upper end face of the cooling pipe 31 contacts the heat-conducting plate 12, and the upper end face of the heat-conducting plate 12 contacts the mold body 20. A second clearance opening 123 is provided on the heat-conducting plate 12 corresponding to the rod body. The upper end of the rod body 41 passes through the second clearance opening 123 and contacts the mold body 20. Specifically, two heat-conducting plates 12 are provided and arranged vertically. The two heat-conducting plates 12 are connected and fixed by an adhesive layer. The heat-conducting plate 12 located on the upper side contacts the mold body 20, and the heat-conducting plate 12 located on the lower side contacts the cooling pipe 31. Preferably, the heat-conducting plate 12 is a thermally conductive silicone plate. In this way, the setting of the heat-conducting plate avoids the cooling pipe from directly contacting the mold body, and uses the heat-conducting plate to conduct the heat of the mold body into the cooling pipe, which improves the stability of the cooling pipe. At the same time, the setting of two heat-conducting plates serves as a buffer contact between the mold body and the base and is assembled on the base, ensuring the stability of the mold body on the base.

[0042] Specifically, a reinforcing rib 121 is provided between the two heat-conducting plates 12, and an mounting groove 122 is provided on the heat-conducting plate 12. The mounting grooves 122 of the two heat-conducting plates 12 are arranged opposite to each other. The upper and lower ends of the reinforcing rib 121 are respectively connected to the mounting grooves 122 of the two heat-conducting plates 12. In this way, the setting of the reinforcing rib improves the structural strength between the two heat-conducting plates, thereby improving the service life of the two heat-conducting plates. At the same time, the setting of the mounting groove facilitates the assembly and connection of the reinforcing rib between the two heat-conducting plates.

[0043] Furthermore, the base 10 is provided with a positioning step 113, which is arranged in a ring shape. The lower edge of the heat-conducting plate 12 is constrained by the positioning step 113, which facilitates the positioning and connection of the heat-conducting plate on the base.

[0044] Furthermore, a protective sleeve 21 is provided on the outer side of the mold body 20. The outer wall of the protective sleeve 21 contacts the inner wall of the cavity 11. Preferably, the surface of the protective sleeve 21 is coated with a wear-resistant layer 211, which is polyurethane wear-resistant paint. In this way, the protective sleeve is provided to ensure the connection between the mold body and the base, and to prevent the mold body from shifting on the base due to external impacts, thus ensuring the use of the mold body. At the same time, the wear-resistant layer improves the wear resistance of the protective sleeve, thereby increasing the service life of the protective sleeve.

[0045] The key design feature of this utility model is that it utilizes the design of each component to absorb and dissipate heat from the mold body through cooling pipes, and uses a liquid delivery device to achieve self-circulation of coolant on the cooling pipes, thereby improving the heat dissipation effect of the mold body and ensuring the stable and consistent quality of the thermoformed products. In conjunction with the ejection mechanism, the mold body is pushed upwards out of the base to facilitate the disassembly and replacement of the mold body, meeting the user's needs, with excellent usability and wide applicability.

[0046] Secondly, the heat-conducting plate avoids direct contact between the cooling pipe and the mold body, and uses the heat-conducting plate to transfer the heat of the mold body to the cooling pipe, improving the stability of the cooling pipe. At the same time, the two heat-conducting plates serve as a buffer between the mold body and the base and are assembled on the base, ensuring the stability of the mold body on the base. Furthermore, the reinforcing ribs improve the structural strength between the two heat-conducting plates, thereby increasing the service life of the two heat-conducting plates.
