Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and particularly relates to a cooling device for an injection mold used in injection molding processing. Background Technique

[0002] Injection molding is a method for manufacturing industrial product shapes. Products usually use rubber injection molding and plastic injection molding. Injection molding can be divided into injection molding, compression molding, and die-casting methods. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a variety of flower patterns and colors, the shape can range from simple to complex, the size can range from large to small, and the product size is precise, the product is easy to update, and it can form parts with complex shapes. During the injection molding process, the mold needs to maintain a specific temperature range to ensure that the workpiece can be successfully formed and have good surface quality and mechanical properties. Even after the workpiece is demolded, the temperature control of the mold still needs to continue for the next injection molding cycle.

[0003] The prior art (publication number: CN 218906216 U) discloses a cooling device for injection mold processing, including an upper mold, a lower mold, and a plurality of positioning rods installed between the upper mold and the lower mold. Grooves are provided on the top surface of the upper mold and the bottom surface of the lower mold. The grooves are filled with thermal conductive silicone, and a cover plate is movably installed at the opening position in the grooves through a plurality of springs. A water cooling mechanism and a heat dissipation mechanism are arranged in the grooves.

[0004] Although the above patent absorbs the heat in the mold through the arrangement of grooves, thermal conductive silicone, cover plates, a water cooling mechanism, and a heat dissipation mechanism, and the water cooling mechanism can export some of the heat in the thermal conductive silicone, and the plurality of heat conduction plates in the heat dissipation mechanism can also disperse and conduct some of the heat in the thermal conductive silicone, there are the following drawbacks. When in use, after the workpiece is demolded, only the inside of the mold can be cooled, and the surface of the mold cannot be effectively cooled, resulting in a continuously high surface temperature, which will increase the cooling time of the workpiece and extend the cycle of each injection molding cycle, thereby reducing production efficiency. Therefore, further improvement is needed. For this reason, we propose a cooling device for an injection mold used in injection molding processing. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a cooling device for an injection mold used in injection molding processing, which can effectively solve the problem of being unable to dissipate heat from the inside and surface of the mold simultaneously.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An injection mold cooling device for injection molding processing, including an injection molding machine, there are two molds arranged on the injection molding machine, a cross plate is installed at the rear end of the injection molding machine, a vertical plate is installed in the middle of the upper end of the cross plate, a temperature reduction component is installed at the rear part of the upper end of the cross plate, a chute is opened in the middle of the rear end of the vertical plate, a motor is installed at the left part of the rear end of the vertical plate, a drying component is installed at the upper part of the rear end of the vertical plate, a rack is slidably connected in the chute, the output end of the motor is fixedly connected with a gear, and the temperature reduction component extends to the front end of the rack.

[0008] Preferably, the cross plate includes a pump body, the pump body is installed at the upper end of the cross plate, the drainage end of the pump body is connected with a first spiral hose, the front end of the first spiral hose movably penetrates through the rear side of the vertical plate and is connected with a hollow plate, and a number of atomizing nozzles distributed in a linear array are inserted and connected to both the left end and the right end of the hollow plate, and the hollow plate is installed at the front end of the rack.

[0009] Preferably, the drying component includes a high-pressure blower, the high-pressure blower is installed at the front end of the vertical plate, the exhaust end of the high-pressure blower is connected with a second spiral hose, the front end of the second spiral hose movably penetrates through the rear side of the vertical plate and is connected with a hollow block, and a number of exhaust holes distributed in a linear array are opened at both the left end and the rear end of the hollow block.

[0010] Preferably, the hollow block is installed at the front end of the hollow plate.

[0011] Preferably, the gear is meshed with the rack, and the rack extends to the front side of the vertical plate.

[0012] Preferably, water pipes are inserted and connected to both the front end and the rear end of the two molds, and the hollow plate and the hollow block are located between the two molds.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting the temperature reduction component, the surface of the mold can be cooled. During use, the pump body is connected with a water tank, the pump body transports cold water into the hollow plate through the first spiral hose, and then sprays out from the atomizing nozzles and sprays onto the surface of the mold, which can quickly absorb heat, thereby cooling the surface of the mold, enabling the inside and the outer surface of the mold to be cooled simultaneously, reducing the temperature difference between the surface and the inside of the mold, avoiding the continuous high temperature of the mold surface, reducing the cooling time of the workpiece and thus the cycle of each injection molding cycle, and improving the production efficiency;

[0015] 2. By setting up a drying component, the water mist ejected by the cooling component can be dried. During use, the power supply of the high-pressure blower is turned on. The high-pressure blower transports hot air through the second spiral hose into the hollow block, and then discharges it from the exhaust holes, blowing towards the surface of the mold, accelerating the evaporation of water, preventing the influence of water droplets on subsequent processes, ensuring the continuity and stability of the production process, improving the reliability of the process. At the same time, when the water evaporates, it can absorb the heat on the surface of the mold, further reducing the temperature of the mold surface and improving the cooling efficiency.
