Description

Technical Field

[0001] This utility model relates to the field of injection mold cooling, and more specifically, to an external cooling system for injection molds. Background Technology

[0002] In injection molding, mold temperature control is crucial to product quality and production efficiency. Traditional built-in cooling channels are complex to design and manufacture, prone to uneven cooling due to space constraints within the mold, and inconvenient and costly to maintain and replace. As industry demands for quality and efficiency increase and mold structures become more complex, traditional methods are no longer sufficient. Against this backdrop, external cooling systems for injection molds have emerged, providing a new solution for injection molding production by incorporating cooling mechanisms outside the mold.

[0003] Traditional injection molds use built-in cooling channels, which have several drawbacks. Firstly, the design and fabrication of built-in cooling channels are complex, requiring customization based on the specific shape and structure of the mold, increasing manufacturing difficulty and cost. Secondly, the limited internal space of the mold restricts the layout and size of the cooling channels, leading to uneven cooling and affecting the dimensional accuracy and surface quality of the molded products. Furthermore, when the mold needs repair or the cooling channels need replacement, the entire mold must be disassembled, resulting in cumbersome operations, high maintenance costs, and reduced production efficiency.

[0004] Therefore, we have made improvements to this by proposing an external cooling system for injection molds. Utility Model Content

[0035] To address the technical problems in the background section, the following external cooling system for injection molds is provided:

[0036] Combination Figure 1 - Figure 6 As shown, the present invention provides an external cooling system for injection molds, including a base box 1. An operating table 2 is fixedly installed on the upper surface of the base box 1, and a groove 3 is formed on the upper surface of the operating table 2. A mold body 4 is placed inside the groove 3, and cooling mechanisms 5 are provided on both sides of the mold body 4. A swing mechanism 6 is provided between the cooling mechanism 5 and the operating table 2. A drain hole 7 is formed on the surface of the groove 3. A filter mechanism 8 is provided inside the base box 1, and a heat exchanger 9 is fixedly installed inside the base box 1 below the filter mechanism 8. The cooling mechanism 5 includes a water outlet pipe 501, and there are two water outlet pipes 501. The two water outlet pipes 501 are respectively provided on both sides of the mold body 4. A connecting block 502 is fixedly installed on one end of the water outlet pipe 501, and a nozzle 503 is fixedly installed on one side of the connecting block 502.

[0037] In this embodiment: the base box 1 serves as a supporting foundation, containing cooling water. An operating platform 2 is mounted on its upper surface, with a groove 3 on the platform 2 for placing the mold body 4. Cooling mechanisms 5 are located on both sides of the mold body 4. Through the coordinated action of the water outlet pipe 501, connecting block 502, and nozzle 503, water is sprayed from the nozzles to cool the mold. Simultaneously, a swing mechanism 6 is provided between the cooling mechanism 5 and the operating platform 2, allowing the nozzle 503 to swing flexibly, expanding the cooling range. Furthermore, drainage holes 7 are provided on the surface of the groove 3 to facilitate the recovery of the cooling medium back to the base box 1. After filtration by the filter mechanism 8 and heat exchange by the heat exchanger 9 within the base box 1, the medium is recycled, making it both environmentally friendly and energy-saving.

[0038] In a preferred embodiment, a submersible pump 504 is fixedly installed inside the bottom box 1, and a water pump pipe 505 and a drain pipe 506 are fixedly installed on both sides of the submersible pump 504, respectively. A connecting tee 507 is fixedly installed at the other end of the drain pipe 506, and the other ends of the two water outlet pipes 501 extend into the bottom box 1. The two ends of the upper side of the connecting tee 507 are respectively connected to the water outlet pipes 501 on both sides.

[0039] In this embodiment: the submersible pump 504 is placed in the cooling water inside the base tank 1, with a water intake pipe 505 and a water outlet pipe 506 connected to its two sides respectively. The water intake pipe 505 can quickly and in large quantities draw cooling water, providing sufficient power for the cooling circulation; the water outlet pipe 506 delivers the drawn cooling water to the connecting tee 507. The connecting tee 507 divides the water flow in two, distributing the cooling water to the two outlet pipes 501, thereby providing a continuous and stable cooling medium for the cooling of both sides of the mold, ensuring the consistency and efficiency of the mold cooling effect.

[0040] In a preferred embodiment, the swing mechanism 6 includes a fixed box 601, which is fixedly installed on the upper surface of the operating table 2. A rotating rod 602 is rotatably connected inside the fixed box 601, and the top end of the rotating rod 602 is fixedly connected to the lower surface of the connecting block 502. A connecting piece 603 is fixedly installed on the outside of the lower end of the rotating rod 602.

[0041] In this embodiment: a rotatable rotating rod 602 is cleverly set inside the fixed box 601. The top end of the rotating rod 602 is tightly fixedly connected to the lower surface of the connecting block 502, so that the rotation of the rotating rod 602 can directly drive the connecting block 502 and the nozzle on it to move synchronously. A connecting piece 603 is fixedly installed on the lower end of the rotating rod 602. The swing of the connecting piece 603 drives the nozzle 503 to swing, thereby meeting the cooling requirements of the mold.

[0042] In a preferred embodiment, a mounting plate 604 is fixedly installed inside the fixing box 601, and a motor 605 is fixedly installed on the lower surface of the mounting plate 604. The output end of the motor 605 is fixedly connected to a rotating disk 606, and a protrusion 607 is fixedly installed on the outer side of the upper surface of the rotating disk 606. The protrusion 607 is slidably connected to the connector 603.

[0043] In this embodiment: The mounting plate 604 is securely installed inside the fixed box 601, providing a reliable mounting platform for the motor 605. The motor 605, which is fixedly installed on the lower surface of the mounting plate 604, serves as a power source. When the motor 605 starts, it can drive the rotating disk 606 to rotate stably. During the rotation, the protrusions 607 on the surface of the rotating disk 606 will slide along the groove on the surface of the connector 603, thereby pushing the connector 603 to drive the rotating rod 602 to swing back and forth, ultimately enabling the nozzle 503 to swing flexibly, which can effectively expand the cooling range and improve the cooling effect of the mold.

[0044] In a preferred embodiment, the filter mechanism 8 includes a fixing strip 801, and two fixing strips 801 are provided on the inner walls of both sides of the bottom box 1. An installation frame 802 is slidably connected between the upper and lower fixing strips 801, and a filter screen 803 is fixedly installed inside the installation frame 802. A handle 804 is fixedly installed on one side surface of the installation frame 802.

[0045] In this embodiment, the upper and lower sets of fixing bars 801 are parallel and oppositely distributed, providing a stable sliding track for the mounting frame 802. The mounting frame 802 can be easily pushed into or pulled out of the base box 1 through the sliding connection with the fixing bars 801. The filter screen 803 fixedly installed inside the mounting frame 802 can effectively intercept impurities and particulate matter in the cooling medium, preventing them from entering key components such as water pumps and heat exchangers, avoiding equipment wear and blockage, and extending the service life of the equipment. The handle 804 fixedly installed on one side surface of the mounting frame 802 facilitates easy movement of the mounting frame 802.

[0046] In a preferred embodiment, the surface of the mold body 4 is provided with a plurality of holes 10, and the interior of the mold body 4 is provided with a plurality of flow grooves 11, which are connected to the holes 10.

[0047] In this embodiment, several holes 10 are carefully formed on the surface of the mold body 4, and several flow channels 11 are cleverly designed inside the mold body 4, with these flow channels 11 connected to the holes 10. When cooling water is sprayed onto the mold surface through the nozzle, some of the cooling water can flow into the flow channels 11 through the holes 10, allowing the cooling water to penetrate deep into the mold and cool it from multiple dimensions. This greatly increases the contact area between the cooling water and the mold, effectively improving cooling efficiency and ensuring that the temperature of all parts of the mold decreases uniformly, thereby helping to improve the molding quality and production efficiency of injection molded products.

[0048] Specifically, the working principle of this solution is as follows:

[0049] In use, the base box 1 serves as a supporting foundation and is filled with cooling water. The submersible pump 504 is placed inside and draws cooling water through the water pumping pipe 505. The water is then transported through the drain pipe 506 to the connecting tee 507, and then split to the water outlet pipes 501 on both sides. Finally, the water is sprayed out by the nozzle 503 on the connecting block 502 to cool the mold body 4 placed in the groove 3 of the operating table 2.

[0050] To expand the cooling range, a swing mechanism 6 is provided between the cooling mechanism 5 and the operating table 2. The motor 605 is mounted on the mounting plate 604 inside the fixed box 601. After starting, it drives the rotating disk 606 to rotate. The protrusion 607 on the rotating disk 606 slides along the connector 603, which can push the connector 603 and the rotating rod 602 to swing back and forth, thereby driving the nozzle 503 to swing flexibly, increasing the spray range and improving the cooling effect.

[0051] The cooled water flows back to the bottom tank 1 through the drain holes 7 on the surface of the groove 3. It first passes through the filtration mechanism 8, where the filter screen 803 inside the mounting frame 802 intercepts impurities, preventing equipment wear and clogging. The mounting frame 802 can be pulled out for maintenance via the handle 804. The filtered water then undergoes heat exchange in the heat exchanger 9 to lower its temperature, achieving recycling. Furthermore, holes 10 are opened on the surface of the mold body 4, with a flow channel 11 inside, and the two are connected. Cooling water can flow into the flow channel 11 through the holes 10, penetrating deep into the mold for multi-dimensional cooling, improving cooling efficiency, ensuring uniform temperature reduction in all parts of the mold, and improving the molding quality and production efficiency of injection molded products.

[0052] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0053] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
