Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cooling injection molded parts, and in particular relates to a cooling device for injection molded parts. Background Art
[0002] Many common items in life are obtained through injection molding, and this processing method is widely used. Demolding of injection molded parts is one of the more important steps in the processing process. For this step, if the cooling work is not done well, it will seriously affect the quality of the injection molded parts. Under normal circumstances, the temperature of the plastic injected into the mold is about 200 degrees, and the temperature of the injection molded parts when taken out of the mold cavity after molding is below 60 degrees. After the injection molded parts are ejected from the mold, they will be directly conveyed to the storage box by the conveyor for temporary stacking, and then assembled or packaged for transportation. In this process, since the temperature of the injection molded parts that have just been ejected has not completely dropped to room temperature, when the injection molded parts are stacked together, it is easy to accumulate heat, causing the overall temperature to rise too high. When they are transported and transferred later, they are prone to deformation due to the force during the transportation process when the temperature is too high, especially some injection molded parts with thicker side walls. Do a good job of cooling the injection molded parts after they are ejected from the mold, in fact, it is to allow the plastic products to be solidified and have a certain rigidity, so as to ensure that the injection molded parts will not easily deform, etc., which is also considered part of the quality. Insufficient cooling will cause problems in some parts of the injection molded parts, and the overall detailed workmanship will basically fail to meet customer requirements. Such injection molded parts are undoubtedly unqualified products. Existing cooling methods mainly include air cooling and water cooling. Air cooling is mainly affected by the ambient temperature. When the room temperature is too high, the corresponding heat dissipation effect is slow and unsatisfactory, while water cooling is prone to leakage risks and pollutes the workshop environment. Therefore, the utility model proposes an injection molded part cooling device, which can quickly further cool down the injection molded parts that have just been demolded to prevent deformation, while avoiding being affected by excessive ambient temperature and improving the cooling efficiency of the injection molded parts after demolding.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In this embodiment, through the cooling principle of the vortex tube 2, the cold air is reduced in speed by means of the wind tube 12, the diffuser 5 and the baffle 6, and the area of the cold air is expanded to cool the injection molded parts on the surface of the conveyor.
[0017] In order to facilitate fixing on the conveyor frame, in this embodiment, as a preferred technical solution of the utility model, the fixer includes a fixing shell 8, and a fixing bolt 9 is threadedly connected to one side of the fixing shell 8.
[0018] In order to concentrate the area where the cold air is blown, in this embodiment, as a preferred technical solution of the utility model, the air duct 12 is in an arc-shaped structure, and one end of the delivery pipe 4 is connected to the top center of the air duct 12.
[0019] In order to reduce the wind speed, relatively concentrate and expand and limit a certain cooling area, in this embodiment, as a preferred technical solution of the utility model, the wind diffuser 5 is an overall outward expansion structure, and the cross-section of the baffle 6 is an arc-shaped structure.
