Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for an injection mould of an automobile decorative plate. Background Art

[0002] Injection molding refers to a method in which a heated and molten material is injected into a mold cavity at a high temperature, high pressure and high speed, and a plastic product is obtained after cooling and solidification. Automobile trim is one of the main interior parts of a car. It is installed on the side body or door of the driving space to decorate the car body and provide sound insulation and noise reduction while protecting the passengers. The existing automobile injection molding trim is generally made of plastic material, and the overall surface is generally hard.

[0003] After searching, the Chinese patent with patent announcement number CN109483838B discloses an injection mold for automobile parts with cooling function, including a lower mold, a fan, a telescopic cylinder and a slot, an inner cavity is provided inside the side of the lower mold, the bottom of the inner cavity is connected to the top of the air inlet, a first through hole is provided at the bottom of the lower mold, the push plate is located below the lower mold, the support frame is fixed to the bottom of the lower mold, the slot is provided at the top of the lower mold, a groove is provided inside the block, the other end of the limit rod is located inside the limit groove, a second through hole is provided at the top of the slot, the upper end of the control rod is located above the upper mold, and the top of the control rod is connected to the upper end surface of the upper mold through a second elastic element. The injection mold for automobile parts with cooling function is convenient for the installation and disassembly of the upper mold and the lower mold, and can avoid cracking during the ejection process of the molding mold, thereby ensuring the quality of the molding mold.

[0004] However, the above design still has some shortcomings. In the above design, the wind generated by the rotation of the fan blows toward the injection molded part, thereby accelerating the cooling of the injection molded part. However, as the injection molded part gradually cools down, the temperature around the injection molded part will gradually become higher. The rotation of the fan alone will greatly extend the time required for cooling the injection molded part, resulting in a slow cooling speed and poor cooling effect. Utility Model Content

[0025] Specifically, Figure 1 and Figure 2 As shown, when in use, after the injection molding of the injection molded part is completed, the air in the working chamber 11 can be cooled by the refrigerator 12, and the cold air in the working chamber 11 is pumped into the nozzle 16 by the air pump 10 and sprayed out through the nozzle 16, so as to cool the injection molded part, which solves the problem that the wind force generated by the rotation of the fan blows toward the injection molded part, thereby accelerating the cooling of the injection molded part. However, as the injection molded part is gradually cooled down, the temperature around the injection molded part will gradually become higher. The rotation of the fan alone will greatly extend the time required for cooling the injection molded part, resulting in a slow cooling speed and poor cooling effect.

[0026] A connected air inlet 3 is provided on the other side of the working chamber 11, a filter screen plate 2 is movably provided inside the air inlet 3, a fixing mechanism 9 is provided at both ends of the filter screen plate 2, the fixing mechanism 9 includes a mounting cavity 902, and the mounting cavity 902 is provided on the outer walls at both ends of the filter screen plate 2, a spring 905 is provided inside the mounting cavity 902, and the ends of the two springs 905 that are away from each other are fixedly connected to a movable plate 901, and the ends of the two movable plates 901 that are away from each other are provided with a limiting groove 903, and a limiting block 904 is movably provided inside the limiting groove 903, and the limiting block 904 is fixedly connected to the movable plate 901;

[0027] Specifically, Figure 2 and Figure 3 As shown, when in use, the filter screen plate 2 can be used to filter dust in the air entering through the air inlet 3 to prevent dust from entering the working chamber 11 with the air flow. At the same time, when the filter screen plate 2 needs to be disassembled and cleaned after a long period of use, the limit blocks 904 in the two limit grooves 903 can be pressed to make the limit blocks 904 move in a direction away from the limit grooves 903 and close to the installation chamber 902. When the limit blocks 904 move to a suitable position, the filter screen plate 2 is pulled along the outside until the filter screen plate 2 is detached from the air inlet 3, thereby completing the disassembly of the filter screen plate 2. After cleaning and drying, place the filter screen plate 2 at the opening of the air inlet 3 and press the two limit blocks 904 again. When the limit blocks 904 move to the appropriate position, push the filter screen plate 2 toward the inside of the air inlet 3, and the movement of the filter screen plate 2 drives the limit blocks 904 to move. When the limit blocks 904 move to the connecting point between the installation cavity 902 and the limit groove 903, the spring 905 is no longer subjected to external force, and will drive the limit blocks 904 to be inserted into the limit groove 903, thereby completing the fixation of the filter screen plate 2. By facilitating the disassembly and assembly of the filter screen plate 2, the filtering effect of the filter screen plate 2 can be effectively guaranteed.

[0028] Working principle: In the present application, after the injection molding of the injection molded part is completed, the air in the working chamber 11 can be cooled by the refrigerator 12, and the cold air in the working chamber 11 can be pumped into the nozzle 16 by the air pump 10 and sprayed out through the nozzle 16, so as to cool the injection molded part. Secondly, the filter plate 2 can be used to filter the dust in the air entering through the air inlet 3 to prevent the dust from entering the working chamber 11 with the air flow. At the same time, when the filter plate 2 needs to be disassembled and cleaned after a long period of use, the limit block 904 in the two limit grooves 903 can be pressed to make the limit block 904 move in the direction away from the limit groove 903 and close to the installation chamber 902. When the limit block 904 moves to a suitable position, it moves along the outer side. Pull the filter screen plate 2 until the filter screen plate 2 is disengaged from the air inlet 3, thereby completing the disassembly of the filter screen plate 2. After the filter screen plate 2 is cleaned and dried, place the filter screen plate 2 at the opening of the air inlet 3 and press the two limit blocks 904 again. When the limit blocks 904 move to the appropriate position, push the filter screen plate 2 toward the inside of the air inlet 3, and the movement of the filter screen plate 2 drives the limit blocks 904 to move. When the limit blocks 904 move to the connecting point between the installation cavity 902 and the limit groove 903, the spring 905 is no longer subjected to external force, and will drive the limit blocks 904 to be inserted into the limit groove 903, thereby completing the fixation of the filter screen plate 2. By facilitating the disassembly and assembly of the filter screen plate 2, the filtering effect of the filter screen plate 2 can be effectively guaranteed.
