Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to a water cooling device for plastic molds. Background Technology

[0002] A plastic mold is a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes in the mold's punch, die, and auxiliary molding systems allow for the production of a range of plastic parts of different shapes and sizes. Water cooling facilitates rapid molding of products within the plastic mold.

[0003] A search revealed patent number CN219058641U, which discloses a water cooling device for plastic molds. This device uses a magnet, inner tube, square tube, filter tube, and filter element to magnetize the water entering the mold before filtration, preventing scale buildup and ensuring good cooling performance. However, this device directly contacts the plastic product for cooling, which can negatively impact the appearance and finish of the molded product. Therefore, we propose a water cooling device for plastic molds. Utility Model Content

[0004] The purpose of this invention is to provide a water cooling device for plastic molds.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a water cooling device for plastic molds, comprising a base, a lower mold mounted on the upper end of the base, a heat-conducting plate disposed on the inner side of the lower mold, a heat dissipation plate disposed on the lower end of the heat-conducting plate, a circulation pipe mounted on the lower side of the heat dissipation plate, a circulation pump disposed on the left side of the inner side of the circulation pipe, a support plate mounted on the lower end of the circulation pipe, a water tank mounted on the right side of the inner side of the base, a dustproof plate mounted on the lower end of the base, and sliding boxes mounted on both sides of the upper end of the base.

[0006] Preferably, a mounting bracket is fixedly connected to the center of the inner side of the base, and a cooling fan is fixedly connected to the inner side of the mounting bracket.

[0007] Preferably, a water inlet pipe is fixedly connected to the right side of the water tank, and the water inlet pipe passes through the base.

[0008] Preferably, a drain pipe is fixedly connected to the lower end of the water tank, and a solenoid valve is fixedly connected to the drain pipe.

[0009] Preferably, an upper mold is installed at the upper end of the lower mold, fixing blocks are installed on both sides of the upper mold, connecting blocks are installed on both sides of the lower mold, a first threaded rod is provided through the front of the fixing block, a first nut is installed on the first threaded rod, a connecting plate is installed at the upper end of the upper mold, a second threaded rod is provided through the left side of the connecting plate, a second nut is installed on the second threaded rod, and a hydraulic telescopic mechanism is provided at the upper end of the connecting plate.

[0010] Preferably, the lower sides of both ends of the lower mold are fixedly connected to sliding plates, and the sliding plates are slidably connected to the sliding box.

[0011] Preferably, an injection tube is provided through the center of the upper end of the upper mold, and the first threaded rod passes through the connecting block.

[0012] Using the above technical solution, the heat from the lower mold is guided to the heat sink through the cooperation of the heat conduction plate and the heat sink. Then, the circulation pump is started, which draws water from the water tank into the circulation pipe and circulates the water. During the circulation process, the water carries away the heat from the heat sink, thus cooling the heat sink. The heat sink and heat conduction plate can continue to dissipate heat from the lower mold. In addition, the cooling fan can accelerate the cooling of the water in the circulation pipe, allowing the water in the circulation pipe to cool the heat sink again. Then, the water in the water tank can be quickly replaced through the cooperation of the inlet and outlet pipes. The water cooling device for plastic molds can dissipate heat without contacting the plastic product inside the lower mold, preventing the water from directly contacting the plastic product and resulting in better molding effect of the plastic product.

[0013] Using the above technical solution, the connecting block and connecting plate are connected to the fixed block and the upper mold respectively through the cooperation of the first and second threaded rods. Then, the hydraulic telescopic machine is started, which drives the upper mold and the lower mold to rise, causing the sliding plates on both sides of the lower mold to slide out of the sliding box, thus eliminating the connection between the lower mold and the base. Then, the first nut is rotated, which eliminates the connection between the connecting block and the fixed block, and the lower mold is removed. Then, the second nut is rotated again, which eliminates the connection between the connecting plate and the upper mold, and the upper mold is removed. The replaced upper mold is then reconnected to the connecting plate through the second threaded rod, and the replaced lower mold is connected to the fixed block through the cooperation of the connecting block and the first threaded rod. Then, the hydraulic telescopic machine is started, which drives the lower mold to descend, causing the sliding plate to engage in the sliding box. This water cooling device for plastic molds can quickly load and unload the lower mold and the upper mold, facilitating the installation of different plastic molds according to actual conditions.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: a water cooling device for plastic molds, including a base 1, a lower mold 2 installed on the upper end of the base 1, a heat-conducting plate 3 arranged on the inner side of the lower mold 2, a heat dissipation plate 4 arranged on the lower end of the heat-conducting plate 3, a circulation pipe 5 installed on the lower side of the heat dissipation plate 4, a circulation pump 6 arranged on the left side of the inner side of the circulation pipe 5, a support plate 7 installed on the lower end of the circulation pipe 5, a water tank 10 installed on the right side of the inner side of the base 1, a dustproof plate 25 installed on the lower end of the base 1, and sliding boxes 13 installed on both sides of the upper end of the base 1.

[0022] A mounting bracket 8 is fixedly connected to the center of the inner side of the base 1, and a cooling fan 9 is fixedly connected to the inner side of the mounting bracket 8.

[0023] A water inlet pipe 11 is fixedly connected to the right side of the water tank 10, and the water inlet pipe 11 passes through the base 1.

[0024] A drain pipe 12 is fixedly connected to the lower end of the water tank 10, and a solenoid valve is fixedly connected to the drain pipe 12.

[0025] In use, water is injected into the water tank 10 through the water inlet pipe 11. When the plastic product inside the lower mold 2 is being produced, a large amount of heat is generated inside the lower mold 2. At this time, the heat-conducting plate 3 located on the inner side of the lower mold 2 absorbs the heat inside the lower mold 2 and transfers it to the heat sink 4. Then, the circulation pump 6 and the cooling fan 9 are started, so that the circulation pump 6 and the cooling fan 9 run together, thereby drawing water from the water tank 10 into the circulation pipe 5 and circulating the water inside the circulation pipe 5. During the circulation process inside the circulation pipe 5, the water carries away the heat from the heat sink 4, thereby cooling the heat sink 4, so that the heat sink 4 and the heat-conducting plate 3 can continue to cool the lower mold. 2. Heat dissipation is achieved by the cooling fan 9 generating airflow to cool the water inside the upper circulation pipe 5. The second threaded rod 20 below the cooling fan 9 also blocks external dust and debris while the cooling fan 9 is cooling the circulation pipe 5. When water needs to be replaced, the solenoid valve and circulation pump 6 are opened, allowing the water inside the water tank 10 to be discharged through the drain pipe 12. Under the operation of the circulation pump 6, the water inside the circulation pipe 5 also flows into the water tank 10 and is discharged. The water cooling device used for plastic molds can dissipate heat without contacting the plastic product inside the lower mold 2, preventing water from directly contacting the plastic product and resulting in better molding of the plastic product.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a water cooling device for plastic molds, wherein an upper mold 14 is installed on the upper end of the lower mold 2, and fixing blocks 16 are installed on both sides of the upper mold 14, and connecting blocks 15 are installed on both sides of the lower mold 2. A first threaded rod 17 is provided through the front of the fixing block 16, and a first nut 18 is installed on the first threaded rod 17. A connecting plate 19 is installed on the upper end of the upper mold 14, and a second threaded rod 20 is provided through the left side of the connecting plate 19. A second nut 21 is installed on the second threaded rod 20, and a hydraulic telescopic mechanism 22 is provided on the upper end of the connecting plate 19.

[0028] Slide plates 23 are fixedly connected to the lower sides of both ends of the lower mold 2, and slide plates 23 are slidably connected to sliding boxes 13.

[0029] An injection tube 24 is provided through the center of the upper end of the upper mold 14, and the first threaded rod 17 passes through the connecting block 15.

[0030] Specifically, when it is necessary to replace the lower mold 2 and the upper mold 14, the first threaded rod 17 and the second threaded rod 20 are inserted into the fixing block 16 and the upper mold 14, respectively. Then, the first nut 18 and the second nut 21 are rotated, so that the connecting block 15 and the connecting plate 19 are connected to the fixing block 16 and the upper mold 14, respectively. Then, the hydraulic telescopic machine 22 is started, so that the hydraulic telescopic machine 22 drives the upper mold 14 to rise. At this time, the lower mold 2, which is connected to the upper mold 14, will also rise with the upper mold 14, so that the sliding plates 23 on both sides of the lower mold 2 slide out of the sliding box 13, thereby eliminating the connection between the lower mold 2 and the base 1. Then, the first nut 18 is rotated, so that the first nut 18 loses its fixation on the first threaded rod 17. Then, the first threaded rod 17 is pulled out, so that the connecting block 15... The connection between the lower mold 2 and the fixed block 16 is removed. Then, the lower mold 2 is removed. The second nut 21 is rotated again to remove the fixation of the second nut 21 to the second threaded rod 20. The second threaded rod 20 is then pulled out to remove the connection between the connecting plate 19 and the upper mold 14. The upper mold 14 is then removed. The replaced upper mold 14 is then reconnected to the connecting plate 19 via the second threaded rod 20. The replaced lower mold 2 is then connected to the fixed block 16 via the connecting block 15 and the first threaded rod 17. The hydraulic telescopic machine 22 is then started to drive the lower mold 2 to descend, thereby causing the slide plate 23 to engage in the sliding box 13. This plastic mold water cooling device can quickly load and unload the lower mold 2 and the upper mold 14, making it convenient to install different plastic molds according to actual conditions.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
