Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to a cooling mechanism for a low wind resistance spoiler forming mold. Background Technique

[0002] At present, an automobile spoiler refers to a component installed on the rear trunk lid of a sedan, similar to an inverted aircraft tail wing. Some automobiles are equipped with a front spoiler, commonly known as an air dam. Some automobiles are equipped with side skirts on the side, which are also a type of spoiler. The rear spoiler is actually also called the "automobile tail wing"; on the one hand, it adds a sense of motion to the sedan's appearance; on the other hand, its more important role is to effectively reduce the air resistance generated when the vehicle is driving at high speed, which not only saves fuel but also improves the driving stability of the vehicle.

[0003] The production of spoilers mostly uses injection molds. The injection molds for spoilers are generally large in volume. After injection molding, it is necessary to wait for natural cooling. However, the natural cooling method is very time-consuming, and it is impossible to continue producing spoilers during the waiting for cooling process, resulting in a long production cycle for a single spoiler, which greatly affects the production effect of the spoiler.

[0004] Therefore, we have designed a cooling mechanism for a low wind resistance spoiler forming mold. Content of the Utility Model

[0013] Beneficial effects

[0014] The utility model provides a cooling mechanism for a low wind resistance spoiler forming mold, which has the following beneficial effects:

[0015] The cooling mechanism of the low wind resistance spoiler forming mold cools and dissipates heat from the formed mold by arranging the first cooling water pipe and the second cooling water pipe.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 5 , the present invention provides a technical solution: including a lower mold 1 and an upper mold 3. An installation groove is opened in the lower mold 1. The installation groove is provided with a first cooling water pipe 13 and a second cooling water pipe 14 for cooling the molding mold. The first cooling water pipe 13 is arranged in a serpentine shape. The second cooling water pipe 14 is spirally wound above the first cooling water pipe 13, and the first cooling water pipe 13 is hermetically connected to the second cooling water pipe 14. It should be noted that the first cooling water pipe 13 is arranged in a serpentine shape below the molding cavity of the lower mold 1, and the second cooling water pipe 14 is spirally wound around the molding cavity of the lower mold 1. The cross sections of the first cooling water pipe 13 and the second cooling water pipe 14 are both rectangular. The purpose is to increase the contact area between the cold water and the molding cavity of the lower mold 1 and improve the heat dissipation speed. If a large water tank is directly opened, the large cross-sectional area of the water tank will affect the flow rate of the cold water; a water tank 6 for providing cold water for the first cooling water pipe 13 and the second cooling water pipe 14 is fixedly connected to the lower mold 1.

[0024] A plurality of positioning holes 2 are opened at the top of the lower mold 1. A plurality of positioning pins 4 are fixedly connected to the bottom of the upper mold 3. The plurality of positioning pins 4 are respectively adapted to the plurality of positioning holes 2. Two pull rings 5 are fixedly connected to the top of the upper mold 3. By setting the pull rings 5, it is convenient for the staff to lift the upper mold 3 from the lower mold 1, which is convenient for demolding. During use, the positioning pins 4 on the upper mold 3 are inserted into the positioning holes 2 of the lower mold 1, and then the spoiler is injection molded.

[0025] The top of the water tank 6 is provided with a first connection port 11 and a second connection port 12. The end of the first cooling water pipe 13 is sealedly connected with the water inlet pipe 9, which is inserted into the first connection port 11 and is sealedly connected to the water tank 6; the end of the second cooling water pipe 14 is sealedly connected with the water outlet pipe 10, which is inserted into the second connection port 12 and is sealedly connected to the water tank 6; one end of the water inlet pipe 9 inserted into the water tank 6 is sealedly connected with a connecting pipe 17, and a water pump 18 is provided in the water tank 6, and the water pump 18 is connected to the connecting pipe 17. Sealed connection, a water pump 18 is provided with a pumping pipe; a water chiller 19 for cooling warm water is provided in the water tank 6. It should be noted that the purpose of providing the water chiller 19 is to convert the warm water that absorbs heat into cold water for subsequent recycling. The water chiller 19 is a prior art and will not be elaborated on here; the side wall of the water tank 6 is sealedly connected with a water injection pipe 7, and a valve 8 is provided on the water injection pipe 7; an electric hydraulic rod 15 is fixedly connected to the lower mold 1, and the output end of the electric hydraulic rod 15 is fixedly connected to the top plate 16.

[0026] When in use, the staff opens the valve 8 and injects cold water into the water tank 6 through the water injection pipe 7. After the spoiler is injection molded, the water pump 18 is started to pump the cold water in the water tank 6 into the water inlet pipe 9. The cold water in the water inlet pipe 9 circulates through the first cooling water pipe 13 and the second cooling water pipe 14. During the circulation process, the cold water takes away the heat in the molding cavity of the mold 1, so that the mold after molding is quickly cooled. Finally, the water that absorbs the heat enters the water tank 6 through the outlet pipe 10, and is cooled by the chiller 19 to finally realize the cold water circulation, so as to water-cool the molding mold. The cooling time of the molding mold is shortened by water cooling, and the production cycle of a single spoiler is shortened, thereby greatly improving the production efficiency of the spoiler. It should be noted that an external power supply is connected to the water pump 18, and the line connection is waterproofed. Line waterproofing is an existing mature technology. The external power supply includes a battery for providing power to the water pump 18 and a control switch for controlling the start and stop of the water pump 18. The external power supply is an existing technology and will not be elaborated on here.

[0027] Working principle: open valve 8 and inject cold water into water tank 6 through water injection pipe 7. After the spoiler is injection molded, start water pump 18 to pump cold water in water tank 6 into water inlet pipe 9. Cold water in water inlet pipe 9 flows through first cooling water pipe 13 and second cooling water pipe 14. During the circulation process, cold water takes away the heat in the molding cavity of mold 1, so that the mold after molding is cooled quickly. Finally, the water that absorbs heat enters water tank 6 through outlet pipe 10, and is cooled by chiller 19 to finally realize cold water circulation so as to cool the molding mold by water.
