Technical Field

[0001] This utility model relates to the field of night light production technology, and in particular to a cooling and molding device for night light production. Background Technology

[0002] The nightlight production cooling and molding device is a key piece of equipment in the nightlight production process. It rapidly cools and fixes the shape of the injection-molded or die-cast nightlight components to achieve a qualified product form. Through the coordinated operation of various parts, this device ensures that the nightlight components are cooled and molded efficiently and with high quality, meeting the needs of large-scale nightlight production and ensuring stable and consistent product quality.

[0003] Existing technologies, such as the utility model patent with publication number CN208992932U, disclose a cooling and forming device for LED bead production. This patent uses a base, with support seats bolted to the four corners of the base's bottom outer wall, and anti-slip pads adhered to the bottom outer walls of the four support seats. Electric push rods are bolted to the two outer walls of the top of the base, and top plates are bolted to the extension rods of the two electric push rods. A support column is welded to the middle outer wall of the top of the base, and a mounting steel plate is bolted to the top outer wall of the support column. Limit blocks are bolted to the two outer walls of the support column. Two electric slide rails are bolted to the top outer wall of the base on the side near the two limit blocks, and sliders are slidably connected to the bottom outer walls of the four electric slide rails. This invention solves the problems that existing cooling and forming devices for LED bead production are mostly complex in structure, occupy a large area, produce poor-quality LED beads, have low work efficiency, and are also costly.

[0004] In the process of producing nightlights using injection molds, there is a problem that existing injection molds often use water cooling for cooling. As the cooling medium carries away the heat from the mold through the cooling water channels, when the cooling medium enters from the injection port, it is gradually poured into the water channels. This gradual pouring can cause errors in the cooling time of different areas, resulting in temperature differences in the mold and a reduction in the quality and precision of the processed products. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where, when the cooling medium enters from the filling port, it is gradually poured into the water channel.

[0011] Preferably, the water inlet connector is connected to the interior of the storage chamber and the water inlet connector is connected to the interior of the first water distribution drain. Through the cooperation of the water inlet connector and the first water distribution drain, the water pumped by the cooling medium pumping mechanism can be evenly injected into different storage chambers, so that the cooling medium can contact the heat dissipation fins and assist the heat dissipation fins in heat dissipation.

[0012] Preferably, the water outlet connector is connected to the interior of the storage chamber and the interior of the second water distribution drain. Through the cooperation of the water outlet connector and the second water distribution drain, the cooling medium in the storage chamber can be sent out so that the cooling medium can flow back to the cooling structure of the pumping mechanism, thereby realizing the recycling of the cooling medium.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a cooling and forming device for the production of night lights, including a first mold 1 and a second mold 2. The second mold 2 is located on the left side of the first mold 1. A guide rod 3 is installed on the inner wall of the first mold 1. The second mold 2 is slidably connected to the surface of the guide rod 3. Cooling components 4 are provided on the inner walls of both the first mold 1 and the second mold 2.

[0024] In this embodiment: the cooling assembly 4 includes a heat-conducting plate 42. The inner walls of mold 1 and mold 2 are both provided with mounting cavities 41. The heat-conducting plate 42 is fixedly connected to the inner wall of the mounting cavity 41. Heat dissipation fins 43 are fixedly connected to the outer side of the heat-conducting plate 42. A sealing frame 44 is fixedly connected to the side surface of the heat dissipation fins 43. A storage cavity 415 is formed at the connection between the sealing frame 44 and the heat dissipation fins 43. A water inlet connector 45 is fixedly connected to the upper end of the sealing frame 44 on the side away from the heat-conducting plate 42. A water distribution drain 46 is installed on the surface of the water inlet connector 45. A water outlet connector 47 is fixedly connected to the lower end of the sealing frame 44 on the side away from the inlet plate. A water distribution drain 48 is installed on the surface of the water outlet connector 47.

[0025] A housing 49 is mounted on the upper surface of the heat sink 43. A rotor 410 is fixedly connected to the upper inner wall of the housing 49. A fan 411 is mounted on the drive end of the rotor 410.

[0026] Specifically, both mold 1 and mold 2 have air inlets 412 on their upper surfaces. The air inlets 412 are connected to the interior of the mounting cavity 41. Both mold 1 and mold 2 have filters 413 fixedly connected to the inner walls of the air inlets 412. The filters 413 can block the air inlets 412 to filter the air entering the air inlets 412, thereby reducing the amount of dust in the air entering the air inlets 412 and adhering to the inside of the air inlets 412, which can cause the air inlets 412 to become clogged after long-term use.

[0027] Specifically, both mold 1 and mold 2 have air outlet holes 414 on their lower surfaces, and the air outlet holes 414 are connected to the interior of the mounting cavity 41.

[0028] In this embodiment, the air after heat exchange can be discharged through the air outlet 414 to improve the air flow efficiency and thus increase the heat dissipation effect of the equipment.

[0029] Specifically, the heat dissipation fins 43 are located inside the mounting cavity 41, and the sealing frame 44 is fixedly connected to the outer surface of the heat conduction plate 42. The heat dissipation fins 43 can increase the contact area between the heat conduction plate 42 and the air, thereby improving the heat exchange efficiency between the heat conducted by the heat conduction plate 42 and the air, and thus increasing the heat dissipation efficiency of the cooling structure.

[0030] In this embodiment: the water inlet connector 45 is connected to the interior of the storage cavity 415, and the water inlet connector 45 is connected to the interior of the water distribution drain 46.

[0031] In this embodiment: by cooperating with the water inlet connector 45 and the water distribution outlet 46, the water source pumped by the cooling medium pumping mechanism can be evenly injected into different storage chambers 415, so that the cooling medium can contact the heat dissipation fins 43 and assist the heat dissipation fins 43 in heat dissipation.

[0032] Specifically, the water outlet connector 47 is connected to the interior of the storage chamber 415 and the interior of the water distribution drain 48. Through the cooperation of the water outlet connector 47 and the water distribution drain 48, the cooling medium in the storage chamber 415 can be sent out so that the cooling medium can flow back to the cooling structure of the pumping mechanism, thereby realizing the recycling of the cooling medium.

[0033] Specifically, the housing 49 is connected to the interior of the air inlet 412, the housing 49 is connected to the interior of the mounting cavity 41, and the fan 411 is located inside the housing 49.

[0034] In this embodiment, the fan 411, driven by the rotor 410, draws outside air into the mounting cavity 41 and increases the airflow speed to increase the heat exchange efficiency between the air and the heat dissipation fins 43.

[0035] Working Principle: During processing, the raw material is injected into the molding cavity formed by the closed mold 1 and mold 2 using an injection molding machine. After injection molding is completed and the molds have cooled, mold 1 and mold 2 are opened, and the workpiece can be removed. Before using the equipment, the inlet and outlet of the pumping mechanism on the injection molding machine are installed on the water distribution drain 46 and water distribution drain 48, respectively. Then, when the equipment is working, the heat-conducting plate 42, together with the heat dissipation fins 43, evenly dissipates the heat from mold 1 and mold 2. At the same time, the injection molding machine controls the rotor 410 to rotate, and the rotor 410 drives the fan 411. The fan 411 rotates and draws outside air into the mounting cavity 41 through the air inlet 412. The air entering the mounting cavity 41 passes through the heat dissipation fins 43 and is discharged through the air outlet 414. When the air passes through the heat dissipation fins 43, it heats the heat-conducting plate 42. The heat is exchanged with the heat dissipation fins 43, thereby improving the heat dissipation efficiency of the heat conduction plate 42 and the heat dissipation fins 43. At the same time, the pumping mechanism on the injection molding machine works to pump the cooling medium to the first water distribution outlet 46. The first water distribution outlet 46, in conjunction with the water inlet connector 45, injects the cooling medium into the storage chamber 415. When the cooling medium passes through the storage chamber 415, it exchanges heat with the heat conduction plate 42 and the heat dissipation fins 43. Then, the cooling medium carrying the heat flows back to the cooling structure of the pumping mechanism through the water outlet connector 47 and the second water distribution outlet 48 to realize the recycling of the cooling medium. By setting the cooling component 4, the equipment can be cooled by a combination of air cooling and water cooling to reduce the problem of uneven cooling when using water cooling, which leads to a decrease in product quality, and further improves the molding effect of the equipment.
