Description

Technical Field

[0001] This utility model relates to a heat dissipation device for a plastic cover, and more particularly to a rapid heat dissipation device for processing plastic covers, which is applied in the field of heat dissipation devices. Background Technology

[0002] In the injection molding process of plastic caps, after molten plastic is injected into the mold cavity, it must be cooled and solidified to set its shape and finally eject. The cooling time directly determines the production cycle and efficiency, and the "rapid heat dissipation device" is a series of technologies and equipment designed to minimize this time while ensuring product quality.

[0003] Chinese patent CN213797849U discloses an injection mold for processing plastic parts that can be rapidly cooled, including a cooling box, a water inlet, a crossbar, a slide, and a box opening. Through the design of a heat dissipation rack that can move up and down, the injection mold can switch back and forth between being in water and outside water, optimizing the cooling structure of the injection mold. This allows water to cover the entire surface of the injection mold, reducing the temperature of the injection mold more evenly, thereby accelerating the curing speed of the plastic inside the injection mold, ensuring the efficiency of the injection mold, and improving the curing efficiency and stability of the injection mold.

[0004] Chinese patent CN222387498U discloses an active heat dissipation injection mold, belonging to the field of mold equipment, including an upper mold base, a lower mold base, a heat dissipation mechanism, and a limiting mechanism; the upper mold is fixedly installed at the bottom of the upper mold base, and the lower mold is fixedly installed at the top of the lower mold base; it accelerates the cooling and molding of the injection molded part, improves the heat dissipation efficiency, and the cooled injection molded part is ejected by an ejector pin after molding, which facilitates material collection.

[0005] Existing heat dissipation methods are mostly focused on mold cooling during the injection molding process. Coolant is introduced through the water channels inside the mold to initially cool the cover. However, for thickened cover plates, due to their greater thickness, more heat accumulates and the heat dissipation path is longer. The cooling inside the mold can only dissipate surface and shallow heat, resulting in a higher overall temperature when the material is discharged. If it is directly put into the next process or stacked for storage, the slow release of heat can easily cause secondary shrinkage, resulting in problems such as cover warping and edge deformation. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing heat dissipation methods are mostly concentrated on mold cooling during the injection molding process. Cooling liquid is introduced into the mold through the water channel to initially cool the cover. However, for thickened cover plates, due to their large thickness, more heat accumulates and the heat dissipation path is long. The cooling inside the mold can only dissipate surface and shallow heat, resulting in a higher overall temperature when the material is discharged. If it is directly put into the next process or stacked for storage, the slow release of heat can easily cause secondary shrinkage, resulting in problems such as cover warping and edge deformation.

[0007] To address the aforementioned problems, this utility model provides a rapid heat dissipation device for plastic cap processing, comprising an injection molding machine body. The injection molding machine body has a pair of matching cap templates installed at its inner end. A material conveying device is fixedly connected to the side end of the injection molding machine body. The material conveying device includes an electric conveyor belt. A multi-dimensional electric guide rail is provided on the right side of the electric conveyor belt. A heat dissipation assembly is fixedly connected to the outer side of the electric conveyor belt. The heat dissipation assembly includes a first intelligent heat dissipation frame and a second heat dissipation frame arranged side-by-side. Two second air-cooled heat dissipation plates are fixedly connected to the side of the first intelligent heat dissipation frame near the electric conveyor belt. Two first air-cooled heat dissipation plates are fixedly connected to the end of the second heat dissipation frame near the electric conveyor belt. Multiple evenly distributed air outlets are fixedly connected to the ends of the first and second air-cooled heat dissipation plates near the material handling arm. Temperature sensors are fixedly connected to multiple positions on the outer side of the second air-cooled heat dissipation plates.

[0008] In the aforementioned rapid heat dissipation device for plastic cap processing, this solution is an integrated system consisting of injection molding, material conveying and heat dissipation components, which can efficiently complete air cooling. By replacing components, it can flexibly adapt to the cooling requirements of workpieces of different thicknesses, without the need for separate equipment configuration, thus reducing production investment.

[0009] As a further improvement of this application, multiple air outlets are connected to external drive fans via pipes, and two drive fans are respectively installed on heat sink bracket two and intelligent heat sink bracket one.

[0010] As a further improvement to this application, a material-picking arm is installed at the output end of the multi-dimensional electrical guide rail, and the lower end of the material-picking arm holds the plastic cover body.

[0011] As a further improvement of this application, the discharge end of the electric conveyor belt is fixedly connected with an inclined guide plate, and the temperature sensor and the plastic cover body cooperate with each other.

[0012] As another improvement of this application, the first and second air-cooled heat sinks located on the lower side extend into the interlayer of the electrical conveyor belt, and the first and second air-cooled heat sinks located on the upper side are located directly above the electrical conveyor belt.

[0013] As a further improvement to this application, an auxiliary component is fixedly connected to the outer end of the electric conveyor belt, the auxiliary component including a plurality of protruding granules formed on the outer side wall of the electric conveyor belt.

[0014] As a further improvement to this application, the outer wall of the electric conveyor belt is fixedly connected with multiple strip grooves, and the multiple strip grooves and protruding particles are arranged at equal intervals.

[0015] In summary, this integrated system, consisting of injection molding, material feeding, and heat dissipation components, can efficiently achieve air cooling. The top-and-bottom enveloping heat dissipation layout can fully cover the workpiece surface. Combined with real-time temperature monitoring and dynamic airflow adjustment, it avoids local deformation caused by delayed heat dissipation in thick-walled structures, quickly locks in product dimensions, and ensures molding accuracy. For thinner workpieces, the auxiliary components serve as replaceable structures. Through the flow gaps formed by surface grooves and protrusions, they enhance air convection during natural cooling, which can avoid material stress damage caused by excessive air cooling and reduce the risk of adhesion during stacking. It is suitable for the heat dissipation and heat dissipation requirements of thin and light workpieces. By replacing components, it can flexibly adapt to the cooling requirements of workpieces of different thicknesses without the need for separate equipment, thus reducing production investment.

[0018] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] First implementation method: Figures 1-5This invention discloses a rapid heat dissipation device for processing plastic caps, comprising an injection molding machine 1, which includes an injection molding machine body 100. A pair of matching cap templates 101 are mounted on the inner end of the injection molding machine body 100. A material conveying device 2 is fixedly connected to the side end of the injection molding machine body 100. The material conveying device 2 includes an electric conveyor belt 200 (model Y80M1-4). A multi-dimensional electric guide rail 201 is provided on the right side of the electric conveyor belt 200. After receiving a signal, the multi-dimensional electric guide rail 201 drives the picking arm 202 at its output end to lift and move. The picking arm 202 is first precisely positioned to the opening and closing area of ​​the cap template 101, and then, through a lowering and raising mechanism at its end, it securely clamps the newly formed thickened plastic cap body 203. Subsequently, driven by the multi-dimensional electric guide rail 201, it moves horizontally, transferring the cap to the feeding end of the electric conveyor belt 200 and placing it on the conveyor belt. Above, a heat dissipation assembly 3 is fixedly connected to the outer side of the electric conveyor belt 200. The heat dissipation assembly 3 includes a first intelligent heat dissipation frame 300 and a second heat dissipation frame 301 arranged side by side. The first intelligent heat dissipation frame 300 integrates a controller. Two second air-cooled heat dissipation plates 303 are fixedly connected to the side of the first intelligent heat dissipation frame 300 near the electric conveyor belt 200. Two first air-cooled heat dissipation plates 302 are fixedly connected to the end of the second heat dissipation frame 301 near the electric conveyor belt 200. Multiple evenly distributed air outlets 306 are fixedly connected to the ends of the first air-cooled heat dissipation plate 302 and the second air-cooled heat dissipation plate 303 near the material picking arm 202. Temperature sensors 304 are fixedly connected to multiple positions on the outer side of the second air-cooled heat dissipation plate 303. The controller is electrically connected to the temperature sensors 304 and the drive fan 305 to receive temperature signals and adjust the output power of the fan accordingly.

[0020] Multiple air outlets 306 are connected to external drive fans 305 via pipes. The model can be SF50-11. Two drive fans 305 are respectively installed on heat sink 2 301 and intelligent heat sink 1 300. The output end of the multi-dimensional electric guide rail frame 201 is equipped with a material picking arm 202. The lower end of the material picking arm 202 clamps the plastic cover body 203. The discharge end of the electric conveyor belt 200 is fixedly connected to an inclined guide plate 204. The temperature sensor 304 and the plastic cover body 203 cooperate with each other. The air-cooled heat sink 1 302 and air-cooled heat sink 2 303 located on the lower side extend into the interlayer of the electric conveyor belt 200. The air-cooled heat sink 1 302 and air-cooled heat sink 2 303 located on the upper side are located directly above the electric conveyor belt 200.

[0021] Figures 1-5After the injection molding machine body 100 of the injection molding equipment 1 completes the injection molding of the thickened plastic cap through a pair of matching cap templates 101, the material conveying equipment 2 starts to operate. The multi-dimensional electrical guide rail frame 201 drives the material picking arm 202 at the output end to move to the cap template 101, clamps the newly formed thickened plastic cap body 203 and transfers it to the electrical conveyor belt 200. During this process, the heat dissipation component 3 on the outside of the electrical conveyor belt 200 starts simultaneously: the intelligent heat dissipation frame 1 300 and the heat dissipation frame 2 301 are arranged side by side. Two air-cooled heat dissipation plates 2 303 are fixed on the side of the intelligent heat dissipation frame 1 300 near the conveyor belt, and two air-cooled heat dissipation plates 1 302 are fixed at corresponding positions on the heat dissipation frame 2 301. The lower air-cooled heat dissipation plates 1 302 and 2 303 extend into the interlayer of the electrical conveyor belt 200, while the upper... The side is located directly above the conveyor belt, forming an upper and lower enclosed heat dissipation area. The air-cooled heat dissipation plate 1 302 and air-cooled heat dissipation plate 2 303 have multiple evenly distributed air outlets 306 at the end near the material picking arm 202. They are connected to the drive fan 305 on the heat dissipation frame 2 301 and the intelligent heat dissipation frame 1 300 through pipes, continuously outputting high-intensity cold air. The temperature sensor 304 installed on the outside of the air-cooled heat dissipation plate 2 303 monitors the initial temperature of the thickened plastic cover body 203 in real time (80-120℃) and feeds the data back to the control system, dynamically adjusting the wind force of the drive fan 305 to ensure that the temperature is reduced to the critical temperature of 40-60℃ within 30-60 seconds. After cooling, the thickened plastic cover body 203 is conveyed to the next process through the discharge end of the electric conveyor belt 200 and the inclined guide plate 204.

[0022] Second implementation method: Figures 6-7 A rapid heat dissipation device for processing plastic caps is shown. An auxiliary component 4 is fixedly connected to the outer end of an electric conveyor belt 200. The auxiliary component 4 includes a plurality of protruding granules 401 formed on the outer side wall of the electric conveyor belt 200. A plurality of strip grooves 400 are fixedly connected to the outer side wall of the electric conveyor belt 200. The plurality of strip grooves 400 and the protruding granules 401 are arranged at equal intervals.

[0023] This embodiment is an independent replacement component, namely auxiliary component 4, suitable for thin plastic caps with a thickness ≤1mm. When processing thin plastic caps, the heat dissipation component 3 in embodiment one can be left unactivated. After the thin plastic cap body 203 is transferred to the electric conveyor belt 200 by the picking arm 202, the protruding granules 401 slightly lift the cap body, so that the bottom of the cap body forms a gap of 0.5-1mm with the surface of the conveyor belt; the strip groove 400 serves as an air circulation channel, accelerating the heat exchange between the cap body and the ambient air, and achieving natural cooling. Since the thin plastic cover has a small heat capacity and an initial temperature of 60-80℃, the natural air flowing through the gap can reduce the temperature to below 40℃ within 20-40 seconds, avoiding warping of the cover due to excessive air cooling. After cooling, the thin plastic cover body 203 is conveyed to the next process through the discharge end of the electric conveyor belt 200 and the inclined guide plate 204. The injection molding equipment 1 and the material conveying equipment 2 in the two embodiments have the same basic structure, and the adaptation of workpieces of different thicknesses is achieved only by whether or not heat dissipation components 3 or auxiliary components 4 are installed.

[0024] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
