Description
Technical Field
[0001] This utility model relates to the field of cooling equipment technology, specifically a cooling device for injection molding production of plastic thermos bottle shells. Background Technology
[0002] The outer shell of a plastic thermos flask is a crucial component, typically made of plastic. It protects the internal insulation layer and provides aesthetic and structural stability to the entire product. The main functions of the outer shell include temperature maintenance, durability, protection, and aesthetic design. The cooling process in injection molding primarily involves using a cooling medium to remove heat from the mold and the product's forming cavity, allowing the molten plastic to solidify and cool. Because the melting temperature of plastics is typically high, the design and operation of the cooling system are critical to controlling product quality.
[0003] Existing injection-molded thermos bottles mostly use fixed molds in production, which leads to reduced efficiency during demolding due to the mold sticking to the product. Furthermore, the slow cooling of the thermos bottle shell during injection molding has many negative impacts on production, including reduced production efficiency, product quality issues, and mold wear. To address these problems, the inventor proposes a cooling device for the injection molding production of plastic thermos bottle shells. Utility Model Content

By incorporating a template injection assembly, a movable template allows for rapid demolding. The movable template enables a portion of the mold to automatically move or open after injection molding, facilitating easier removal of the molded product. Furthermore, the inclusion of a plastic cooling assembly rapidly cools the injection-molded thermos bottle, improving production efficiency, reducing deformation and stress concentration, enhancing product quality, increasing dimensional accuracy, and controlling material shrinkage and deformation.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. In this utility model, by setting a template injection molding component, a movable template is used to enable rapid demolding. The movable template allows a part of the mold to move or open automatically after injection molding, making it easier to remove the molded product from the mold and reducing demolding difficulties caused by excessive friction or mold sticking. The movable template can help the injection molded product cool more evenly through fine adjustment or multiple segmented movements during the injection molding process. Using a movable template makes product demolding smoother, thereby reducing the time required for demolding, shortening the molding time each time, and thus improving overall production efficiency.
[0016] 2. In this utility model, by setting up a plastic cooling component, the insulated outer bottle after injection molding can be cooled quickly. The efficient cooling component can quickly cool the insulated outer bottle after injection molding, which can not only improve production efficiency, reduce deformation and stress concentration, but also improve product quality, increase dimensional accuracy, control material shrinkage and deformation. By shortening the cooling time, the cycle efficiency of the production line can be improved. Rapid cooling helps to reduce the mold cycle time, thereby increasing the production speed. With effective cooling control, the plastic can better maintain the shape and size requirements of the mold during the curing process, thereby ensuring the dimensional accuracy and surface quality of the insulated outer bottle.

[0031] A fixed support rod 207 is fixedly installed on the outside of the cooling device 2. A first fixed block 202 is fixedly installed on the outside of the fixed support rod 207. A third motor 210 is fixedly installed on the outside of the first fixed block 202. A first threaded rod 204 is rotatably connected to the outside of the third motor 210. A second sliding block 203 slides on the outside of the cooling device 2. The first threaded rod 204 is threadedly connected to the second sliding block 203.

[0034] By adopting the above technical solution, the injection molding template 303 and the template extrusion block 109 are attached together, which makes the product demolding smoother, thereby reducing the time required for demolding, shortening the time of each molding, and thus improving the overall production efficiency.
[0035] The first rotating shaft 103 rotates outside the second fixed block 102. The third right angle gear 112 is fixedly installed outside the first rotating shaft 103. The second rotating shaft 104 is rotatably connected to the second fixed block 102. The fourth right angle gear 113 is fixedly installed outside the second rotating shaft 104.

The first right angle gear 110 meshes with the second right angle gear 111.
[0036] By adopting the above technical solution, the meshing of right angle gear 113 and right angle gear 112, and the meshing of right angle gear 110 and right angle gear 111, can drive the rotation of shaft 103 to rotate shaft 105.
[0037] The cooling device 2 is externally fixed with a circular air outlet 201, and a filter screen 206 is externally fixed with the circular air outlet 201.

[0038] By adopting the above technical solution, a cooling fan 205 is connected to the external rotation of the No. 1 motor 209, which can quickly cool the injection-molded insulated outer bottle.
[0039] A transmission device 101 is fixedly installed on the outside of the equipment support plate 1. There are two sets of transmission devices 101 and two sets of template extrusion blocks 109, which are symmetrically distributed.
[0040] By adopting the above technical solution, since the number of transmission device 101 and template extrusion block 109 are both two sets and symmetrically distributed, the sliding of template extrusion block 109 can make a part of the mold move or open automatically after injection molding, thereby making it easier to remove the molded product from the mold.
[0041] Working principle: When a cooling device for injection molding production of a plastic thermos bottle shell is required, the transmission device 101 drives the first rotating shaft 103 to rotate. The rotation of the first rotating shaft 103 drives the second rotating shaft 104 to rotate. The rotation of the second rotating shaft 104 drives the third rotating shaft 105 to rotate. Finally, the rotation of the third rotating shaft 105 drives the second sliding rod 107 to slide outside the first sliding block 106. The movement of the second sliding rod 107 drives the template extrusion block 109 to move and make the template extrusion block 109 and the glue dispensing fixing block 302 fit together. Further, the injection molding device 3 introduces plastic from the connecting pipe 301 into the glue dispensing fixing block 302, and at the same time, the plastic covers the outside of the injection molding template 303. The movable template allows for quick demolding. The movable template allows part of the mold to move or open automatically after injection molding, making it easier to remove the molded product from the mold and reducing demolding difficulties caused by excessive friction or mold adhesion.
[0042] After the outer cylinder of the thermos bottle is covered with plastic, the No. 3 motor 210 drives the No. 1 threaded rod 204 to rotate. The rotation of the No. 1 threaded rod 204 drives the No. 2 sliding block 203 to move downward. The downward movement of the No. 2 sliding block 203 drives the outer shell of the thermos bottle outside the injection molding template 303 to move downward. The heat-absorbing iron sheet 211 absorbs the heat inside the equipment. Furthermore, the No. 1 motor 209 drives the cooling fan 205 to rotate. The rotation of the cooling fan 205 can quickly cool the injection-molded thermos bottle. The efficient cooling components can quickly cool the injection-molded thermos bottle, which can not only improve production efficiency, reduce deformation and stress concentration, but also improve product quality, increase dimensional accuracy, control material shrinkage and deformation, and improve the cycle efficiency of the production line by shortening the cooling time.
