Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing, specifically to an air-cooled structure for injection molding in plastic processing. Background Technology
[0002] Plastic processing is a molding method for plastic products. Molten plastic is injected into a mold under pressure, and then cooled and solidified to obtain various plastic parts. There are special machines for injection molding, such as injection molding machines. The most commonly used plastics are polyethylene, polypropylene, ABS, PA, and polystyrene. Injection molding is a process in which thermoplastic plastic is put into an injection molding machine, heated and melted by the machine, and then extruded into the mold cavity by a screw under pressure, and then cooled and solidified.
[0003] Existing air-cooled structures for injection molding in plastic processing still have certain drawbacks. Traditional air-cooled structures are usually installed inside the injection mold. This structure can only be used when the plastic product is not separated from the injection mold. When the plastic product is removed from the injection mold, it cannot achieve a cooling effect. The plastic product easily retains some residual heat, which can lead to deformation. In addition, the plastic product will produce a certain odor after injection molding, which is not good for the physical and mental health of injection molding personnel. Utility Model Content
[0004] The purpose of this utility model is to provide an air-cooled structure for injection molding in plastic processing, in order to solve the problem that the traditional air-cooled structures mentioned in the background art are usually arranged inside the injection mold. This structure mode can generally only be adapted to the situation where the plastic product and the injection mold are not separated. When the plastic product is separated from the injection mold, the cooling effect cannot be achieved. The plastic product is prone to retaining some residual heat, which leads to deformation of the plastic product. In addition, the plastic product will produce a certain odor after injection molding, which is not conducive to the physical and mental health of injection molding personnel.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-cooled structure for injection molding in plastic processing, comprising a moving injection mold, a fixed injection mold, a left-end wind-cooling frame, and a right-end wind-cooling frame. A moving mold cold water inlet is located above one side of the moving injection mold, and a fixed mold cold water inlet is located above one side of the fixed injection mold. Hot water outlets are located below the other sides of both the moving and fixed injection molds. The left-end wind-cooling frame is located on the bottom surface of the moving injection mold, and the right-end wind-cooling frame is located on the bottom surface of the fixed injection mold. The frame has a left air cooler inside, with a first cold water outlet on the upper side of one side of the left air cooler. The right half of the air-cooled frame has a right air cooler inside, with a second cold water outlet on the upper side of one side of the right air cooler. Both the left and right air coolers have cold water inlets on the lower side of the other side. Both the left and right air coolers have cooling pipes inside. The rear end of the left air cooler has a fan cover, and the fan cover has an air-cooling fan inside. The rear end of the fan cover has a sealing cover, and the sealing cover has an exhaust pipe.
[0006] In a further embodiment, the moving mold cold water inlet and the first cold water outlet are fixedly connected by a first connecting pipe, and the first cold water outlet and the cooling pipe are connected by welding.
[0007] In a further embodiment, the fixed mold cold water inlet and the second cold water outlet are fixedly connected by a second connecting pipe, and the second cold water outlet is connected to the cooling pipe by welding.
[0008] In a further embodiment, the left half of the air-cooling frame is fixedly connected to the injection molding moving mold by a first internal hexagonal bolt, and the left air cooler is fixedly connected to the left half of the air-cooling frame by a second internal hexagonal bolt.
[0009] In a further embodiment, the fan cover is connected to the left half of the air-cooling frame by an inlay, and the sealing cover is fixedly connected to the fan cover by a thread.
[0010] In a further embodiment, both the front ends of the left and right air coolers are provided with protective nets, and the right air cooler is connected to the right half of the air cooling frame by welding.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, cooling pipes can be installed inside both the left and right air coolers. This installation structure can increase the area of the cooling pipes, thereby expanding the cooling range. It not only cools the injection-molded products inside the mold, but also cools the plastic products after demolding, giving it a dual cooling effect and improving the cooling efficiency. Furthermore, an air-cooling fan is installed inside the rear end of the left air cooler. The air-cooling fan can serve two purposes: first, it can accelerate the cooling speed of the left air cooler; second, it can extract the irritating odors generated during injection molding, effectively preventing the injection molding personnel from inhaling the irritating odors, thus protecting the physical and mental health of the injection molding personnel and improving the safety of the working environment.
