Description

Technical Field

[0001] This utility model relates to the field of foam mold cooling technology, specifically a rapid cooling device for automotive foam part molds. Background Technology

[0002] In the mold industry, molds are various molds and tools used in injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods to obtain the desired products. A mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. Polyurethane foaming technology is widely used in the production of automotive interior parts, commonly including seat foam, armrest foam, headrest foam, dashboard foam, and door panel trim foam. Automotive foam part molds need to be cooled after use.

[0003] In the prior art, a rapid cooling device for an automotive foaming part mold, with publication number "CN214820247U", includes a bottom cooling box, a water storage tank fixedly connected to the upper surface of the bottom cooling box, a support rod fixedly connected to the upper surface of the water storage tank, a cooling box fixedly connected to the top of the support rod, a water-proof mechanism fixedly connected to one side of the inner surface of the cooling box, and a telescopic rod fixedly connected to the other side of the inner surface of the cooling box. A side push plate is fixedly connected to the movable end of the telescopic rod. During use, this device ensures that the foaming mold is completely immersed in cooling water for cooling, ensuring cooling efficiency while avoiding uneven cooling.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] When the cooling box in the above-mentioned device cools the foaming mold, the water flow rate is relatively slow, which causes the water near the mold to heat up rapidly. The cold water cannot reach the mold in time, thus affecting the rapid cooling of the mold. In addition, the cold water is generally at the bottom and the hot water is at the top, which easily leads to uneven cooling. As a result, the molten raw materials in the cavity cannot be cooled evenly, affecting the quality of the foamed parts. Utility Model Content

[0006] The purpose of this invention is to provide a rapid cooling device for automotive foam molds to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rapid cooling device for automotive foam part molds includes a cooling box, a drive box fixedly installed below the cooling box, a cooling chamber fixedly installed below the drive box, a partition fixedly installed inside the cooling chamber to divide the cooling chamber into a water storage chamber and a ventilation chamber, a ventilation net fixedly installed on the side of the ventilation chamber away from the partition, and two water pipes connecting the cooling box and the water storage chamber, one of which is connected to a circulating water pump fixedly installed outside the cooling chamber;

[0009] The cooling tank and drive box are equipped with a stirring mechanism to stir the cooling water inside the cooling tank.

[0010] The ventilation chamber is equipped with a cooling mechanism to cool the water storage chamber.

[0011] Preferably, the stirring mechanism includes a low-speed motor fixedly installed in the drive box, a rotating shaft fixedly connected to the low-speed motor, the end of the rotating shaft away from the low-speed motor rotating through the cooling box, and a blade fixedly installed at one end of the cooling box.

[0012] Preferably, the cooling mechanism includes a drive shaft rotatably disposed in a drive box and a ventilation chamber, a first pulley fixedly disposed in the drive box, a second pulley fixedly disposed in the drive box, belts sleeved on the first and second pulleys, a support plate fixedly disposed inside the ventilation chamber, a driven shaft rotatably disposed between the support plate and the inner wall of the ventilation chamber, a fan fixedly disposed on the driven shaft, a first bevel gear fixedly disposed in the ventilation chamber, a second bevel gear fixedly disposed on the driven shaft and meshing with the first bevel gear, and a plurality of heat-absorbing tubes fixedly disposed in the water storage tank, the two ends of the heat-absorbing tubes being connected to the outside of the ventilation chamber and the cooling box, respectively.

[0013] Preferably, the rotating shaft is fitted with a waterproof bearing at the cooling box.

[0014] Preferably, four synchronous electric telescopic rods are fixedly installed at the bottom of the cooling box, and a perforated support plate is fixedly installed on each synchronous electric telescopic rod.

[0015] Preferably, a sealing cover is movably provided on the top of the cooling box, and a threaded rod is rotatably provided in the middle of the sealing cover. A top plate is fixedly provided at one end of the threaded rod, and a turntable is fixedly provided at the other end of the threaded rod outside the cooling box.

[0016] Preferably, a U-shaped copper pipe is fixedly installed inside the water storage tank, a chiller connected to the U-shaped copper pipe is fixedly installed outside the cooling box, and several buckles are provided on the side walls of the cooling box and the sealing cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a stirring mechanism, a low-speed motor drives the paddles in the cooling tank to rotate, which can push the lower-temperature cooling water to the upper layer, accelerate the contact between the lower-temperature cooling water and the mold, prevent the water temperature around the mold from getting too high, and thus accelerate the cooling of the mold. At the same time, it can make the cooling water in the cooling tank flow quickly, and the cooling water temperature at different heights in the cooling tank is the same, which can make the mold cool evenly and improve the quality of the foamed parts in the mold.

[0019] 2. While the low-speed motor is rotating, the cooling mechanism causes the fan in the cooling box to rotate. The fan allows outside air to continuously pass through the heat absorption pipe, thereby carrying away the heat on the wall of the heat absorption pipe and further cooling the circulating cooling water in the water storage tank. This reduces the energy consumption of the chiller and accelerates the cooling of the cooling water in the water storage tank. The cooled cooling water is then pumped back into the cooling box, which further accelerates the cooling of the mold.

[0020] 3. The cooling water used for cooling the mold can be recycled by the circulating water pump, reducing the waste of water resources. In addition, there will be residual residue on the foaming mold. The water in the water storage tank is cooled by the chiller and heat absorption pipe instead of the cooling water directly, which can prevent the residue from clogging the chiller.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] Example 1:

[0031] A rapid cooling device for automotive foam part molds includes a cooling box 1 into which the mold is placed for cooling. A drive box 2 is fixedly installed below the cooling box 1, and a cooling box 3 is fixedly installed below the drive box 2 for rapidly cooling the circulating cooling water. A partition 4 is fixedly installed inside the cooling box 3 to divide the cooling box 3 into a water storage tank 5 and a ventilation tank 6. The water storage tank 5 can store and cool the cooling water used for cooling. A ventilation net 7 is fixedly installed on the side of the ventilation tank 6 away from the partition 4, allowing outside air to enter the ventilation tank 6 through the ventilation net 7 and preventing workers or debris from entering the ventilation tank 6, thus ensuring the safety of workers and the safe operation of the device.

[0032] Two water pipes 8 connect the cooling tank 1 and the water storage tank 5. One of the water pipes 8 is connected to a circulating water pump 9 fixedly installed on the outside of the cooling tank 3. After the circulating water pump 9 is working, it can send the cooling water in the water storage tank 5 into the cooling tank 1 through the water pipe 8 to cool the mold in the cooling tank 1. The cooling water in the cooling tank 1 will flow back to the water storage tank 5 through the other water pipe 8. A U-shaped copper pipe 29 is fixedly installed inside the water storage tank 5. A chiller 30 connected to the U-shaped copper pipe 29 is fixedly installed outside the cooling tank 3. When the chiller 30 is working, it cools the cooling water in the water storage tank 5 through the U-shaped copper pipe 29 and then reuses it.

[0033] Four synchronous electric telescopic rods 23 are fixedly installed at the bottom of the cooling box 1. A perforated support plate 24 is fixedly installed on each of the synchronous electric telescopic rods 23. Raising the support plate 24 via the four synchronous electric telescopic rods 23 allows the mold to be easily placed on it. Lowering the support plate 24 allows the mold to be placed into the cooling box 1. A sealing cover 25 is movably installed on the top of the cooling box 1. Several clips 31 are provided on the side walls of the cooling box 1 and the sealing cover 25 to seal the sealing cover 25 against the top of the cooling box 1, preventing cooling water from overflowing. A threaded rod 26 is rotatably installed in the middle of the sealing cover 25. A top plate 27 is fixedly installed at one end of the threaded rod 26 in the cooling box 1, and a turntable 28 is fixedly installed at the other end of the threaded rod 26 outside the cooling box 1. When the support plate 24 is lowered to its lowest position, the sealing cover 25 is closed. Rotating the turntable 28 moves the threaded rod 26 downwards, and the top plate 27 fixes the mold to the support plate 24, preventing the mold from moving.

[0034] The cooling tank 1 and the drive tank 2 are equipped with a stirring mechanism to stir the cooling water inside the cooling tank 1. The stirring mechanism includes a low-speed motor 10 fixedly installed in the drive tank 2. A rotating shaft 11 is fixedly connected to the low-speed motor 10. The end of the rotating shaft 11 away from the low-speed motor 10 rotates and passes into the cooling tank 1. A blade 12 is fixedly installed at one end of the cooling tank 1. A waterproof bearing 22 is sleeved on the rotating shaft 11 at the cooling tank 1. When the low-speed motor 10 rotates, the rotating shaft 11 drives the blade 12 to rotate below the support plate 24, which can push the low-temperature cooling water in the lower layer of the cooling tank 1 to the upper layer, so that the mold can be cooled down quickly.

[0035] Example 2:

[0036] The ventilation chamber 6 is equipped with a cooling mechanism to cool the water storage chamber 5. The cooling mechanism includes a drive shaft 13 rotatably mounted within the drive box 2 and the ventilation chamber 6. A pulley 14 is fixedly mounted on the drive shaft 13 within the drive box 2, and a pulley 15 is fixedly mounted on the shaft 11 within the drive box 2. A belt 32 is fitted onto both pulleys 14 and 15. The diameter of pulley 14 is smaller than that of pulley 15, resulting in a speed difference; pulley 14 rotates faster than pulley 15. A support plate 16 is fixedly mounted inside the ventilation chamber 6. A driven shaft 17 rotatably mounts between the support plate 16 and the inner wall of the ventilation chamber 6. A fan 18 is fixedly mounted on the driven shaft 17. A bevel gear 19 is fixedly mounted on the drive shaft 13 within the ventilation chamber 6. A bevel gear 20 is fixedly installed on the 7, meshing with bevel gear 19. When the low-speed motor 10 rotates, the rotating shaft 11 drives the pulley 2 15 to rotate, which drives the transmission shaft 13 to rotate through the belt 32 and pulley 14. Then, through bevel gear 19 and meshing bevel gear 20, the driven shaft 17 rotates on the support plate 16, thereby driving the fan 18 to rotate. Several heat-absorbing tubes 21 are fixedly installed in the water storage tank 5. The heat-absorbing tubes 21 are made of copper or other materials that easily absorb heat, such as semiconductors. The two ends of the heat-absorbing tubes 21 are connected to the outside of the ventilation chamber 6 and the cooling box 3, respectively. When the heat-absorbing tubes 21 absorb heat from the cooling water in the water storage tank 5, the fan 18 continuously blows air into the inside of the heat-absorbing tubes 21, thereby carrying away and dissipating the heat on the heat-absorbing tubes 21.

[0037] Working principle: First, the support plate 24 is raised by four synchronous electric telescopic rods 23, and the foam mold is placed on the support plate 24. Then, the support plate 24 is lowered to the lowest position, the sealing cover 25 is closed, and the buckle 31 is locked to seal the cooling box 1. Then, the turntable 28 is rotated, and the top plate 27 is pressed against the mold by the rotation of the threaded rod 26. Then, the circulating water pump 9, the chiller 30 and the low-speed motor 10 are started in sequence.

[0038] The circulating water pump 9 can pump the cooling water in the water storage tank 5 to the cooling box 1. At the same time, the cooling water in the cooling box 1 flows back to the water storage tank 5 through the water pipe 8, thus recycling the water. The high-temperature cooling water flowing back from the cooling box 1 to the water storage tank 5 is cooled by the chiller 30 using the U-shaped copper pipe 29 in the water storage tank 5.

[0039] Meanwhile, the low-speed motor 10 drives the blade 12 to rotate below the support plate 24 via the rotating shaft 11. When the rotating shaft 11 rotates, it drives the transmission shaft 13 to rotate via the pulley 14, the pulley 15 and the belt 32. The transmission shaft 13 then drives the driven shaft 17 to rotate via the bevel gear 19 and the meshing bevel gear 20, causing the fan 18 to rotate. The air generated by the fan 18 blows towards the heat absorption pipe 21, which cools it down quickly, thereby accelerating the cooling of the cooling water in the water storage tank 5, and thus accelerating the cooling of the high-temperature mold in the cooling box 1.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
