[0002] In today's construction, decoration, electronics, automobile manufacturing, and daily consumer goods industries, polymer materials have become indispensable key raw materials. Polymer materials, such as polyethylene (PE), acrylonitrile-butadiene-styrene copolymer (ABS), and polyvinyl chloride (PVC), have successfully replaced some traditional metals and inorganic materials, opening up a vast range of applications thanks to their excellent chemical stability, outstanding insulation properties, good plasticity, and relatively lightweight texture.
[0003] Injection molding, as a mainstream method for processing polymer materials, can efficiently and precisely shape granular or powdered polymer raw materials into products of various shapes and functions. In this process system, the injection mold is like the core "mold," firmly controlling the dimensional accuracy, appearance quality, and internal performance of the product.
[0004] However, the inconvenience of cleaning existing injection molds can affect production efficiency, prolong downtime, and increase maintenance costs. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a polymer material injection mold that is easy to clean, aiming to improve the problems in the prior art where inconvenient cleaning of injection molds affects production efficiency, prolongs downtime, and increases maintenance costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polymer material injection mold that is easy to clean, comprising a frame, a support cover fixedly connected to the top of the frame, a lower mold fixedly connected to the top of the frame, a cylinder fixedly connected to the top of the support cover, an installation plate fixedly connected to the output end of the cylinder, an upper mold fixedly connected to the bottom of the installation plate, and a cleaning mechanism fixedly connected inside the support cover.
[0007] The cleaning mechanism includes an electric slide rail, which is fixedly connected inside the support cover. A slider is slidably connected to the outside of the electric slide rail, and a fixing plate is fixedly connected to the outside of the slider. A motor is fixedly connected to the top of the fixing plate, and a cleaning roller is fixedly connected to the output end of the motor. An adjustment component is fixedly connected to the bottom of the fixing plate.
[0008] Furthermore, the adjustment assembly includes an electric push rod, which is fixedly connected to the bottom of the fixed plate. A second motor is fixedly connected to the output end of the electric push rod, and a cleaning roller is fixedly connected to the output end of the second motor.
[0009] Furthermore, a water tank is fixedly connected inside the frame, a water pump is installed outside the water tank, a delivery pipe is fixedly connected to the output end of the water pump, the end of the delivery pipe away from the water pump is fixedly connected to the outside of the lower mold, a cooling channel is opened inside the lower mold, a return pipe is fixedly connected to the side of the lower mold away from the delivery pipe, and the end of the return pipe away from the lower mold is fixedly connected to the inside of the water tank.
[0010] Furthermore, the water tank has an external water inlet, and a cooler is fixedly connected inside the water tank.
[0011] Furthermore, the bottom of the water pump is fixedly connected to the inside of the frame.
[0012] Furthermore, each of the mounting plates is fixedly connected to a guide rod, and the outer side of each guide rod is slidably connected to the inside of the support cover.
[0013] Furthermore, a guide rod two is fixedly connected inside the support cover, and a fixing plate is slidably connected outside the guide rod two.
[0014] Furthermore, both the conveying pipe and the return pipe are externally connected to the interior of the conveyor frame.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when two sets of molds need to be cleaned, the electric slide rail is first driven to move the slider, the fixed plate, and the cleaning devices on both sides. Once the fixed plate is positioned between the two sets of molds, the electric push rod at the bottom of the fixed plate is driven to move the second motor, which in turn drives the cleaning roller to rotate and clean the lower mold. Next, the cylinder is driven to move the upper mold, allowing the cleaning roller on the upper side of the fixed plate to enter the upper mold. Then, the first motor is driven to operate the cleaning roller. This improves cleaning efficiency and quality, reduces product defects caused by mold contamination, and ensures the quality of subsequent injection molding production.
[0017] 2. In this invention, when rapid cooling of the product is required after injection molding, the water pump starts, drawing cooling water from the water tank and sending it through a delivery pipe into the cooling channel of the lower mold. Because the mold is designed with a cooling channel, the cooling water can evenly cool the mold and the product. After absorbing heat, the water flows out from the other end of the cooling channel and returns to the water tank through a return pipe. The returned hot water is cooled to a suitable temperature by a chiller in the water tank and then drawn back into the mold cooling channel by the water pump. This closed-loop circulation maintains the mold temperature within an appropriate range, ensuring a stable injection molding process and product quality. Attached Figure Description

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.
[0025] Reference Figure 1-4This utility model provides an embodiment of a polymer material injection mold that is easy to clean, including a frame 1. A support cover 2 is fixedly connected to the top of the frame 1, and a lower mold 7 is fixedly connected to the top of the frame 1. A cylinder 3 is fixedly connected to the top of the support cover 2, and a mounting plate 5 is fixedly connected to the output end of the cylinder 3. An upper mold 6 is fixedly connected to the bottom of the mounting plate 5. A cleaning mechanism is fixedly connected inside the support cover 2. The cleaning mechanism includes an electric slide rail 15, which is fixedly connected inside the support cover 2. A slider 16 is slidably connected to the outside of the electric slide rail 15, and a fixing plate 17 is fixedly connected to the outside of the slider 16. A motor 19 is fixedly connected to the top of plate 17. A cleaning roller 22 is fixedly connected to the output end of motor 19. An adjustment assembly is fixedly connected to the bottom of plate 17. The adjustment assembly includes an electric push rod 21, which is fixedly connected to the bottom of plate 17. A motor 20 is fixedly connected to the output end of electric push rod 21. A cleaning roller 22 is fixedly connected to the output end of motor 20. Guide rods 4 are fixedly connected to the top of mounting plates 5. The outside of guide rods 4 is slidably connected to the inside of support cover 2. Guide rods 18 are fixedly connected to the inside of support cover 2. Plate 17 is slidably connected to the outside of guide rods 18.
[0026] When using this device, first drive the electric slide rail 15 to move the slider 16, the fixed plate 17 and the cleaning devices on both sides toward the mold. After the fixed plate 17 moves to the middle of the two sets of molds, it is ready to clean the lower mold 7. Then drive the electric push rod 21 at the bottom of the fixed plate 17 to make the motor 20 drive the cleaning roller 22 to rotate and clean the lower mold 7. At the same time, the cylinder 3 drives the upper mold 6 to move, so that the cleaning roller 22 on the upper side of the fixed plate 17 enters the interior of the upper mold 6. Then start the motor 19 to drive the cleaning roller 22 to rotate and clean the upper mold 6.
[0027] Reference Figure 1 , Figure 3 and Figure 4 A water tank 8 is fixedly connected inside the frame 1. A water pump 9 is installed outside the water tank 8. A delivery pipe 10 is fixedly connected to the output end of the water pump 9. The end of the delivery pipe 10 away from the water pump 9 is fixedly connected to the outside of the lower mold 7. A cooling channel 11 is opened inside the lower mold 7. A return pipe 12 is fixedly connected to the side of the lower mold 7 away from the delivery pipe 10. The end of the return pipe 12 away from the lower mold 7 is fixedly connected to the inside of the water tank 8. A water inlet 14 is opened outside the water tank 8. A cooler 13 is fixedly connected inside the water tank 8. The bottom of the water pump 9 is fixedly connected to the inside of the frame 1. The outside of the delivery pipe 10 and the return pipe 12 are both connected through the inside of the conveyor frame 1.
[0028] Secondly, when the injection molded product needs to be cooled quickly, the water pump 9 draws water from the water tank 8 and sends it to the cooling channel 11 of the lower mold 7 through the delivery pipe 10. After absorbing heat, the cooling water returns to the water tank 8 through the return pipe 12. The returned hot water is cooled to a suitable temperature by the cooler 13 (using refrigerant or other cooling media) in the water tank 8, and then drawn into the cooling channel 11 by the water pump 9, forming a closed loop circulation, stabilizing the mold temperature and ensuring the injection quality.
[0029] Working Principle: When using this device, firstly, the electric slide rail 15 is driven, which moves the slider 16 and the fixed plate 17 along the slide rail direction. This process causes the fixed plate 17 and the cleaning devices on both sides to move together, gradually approaching the mold position. When the fixed plate 17 moves to the middle position between the two sets of molds, the cleaning device is ready to start cleaning the lower mold 7. This process ensures proper alignment between the cleaning device and the mold. Next, the electric push rod 21 at the bottom of the fixed plate 17 is driven to move further, and the electric push rod 21 drives the second motor 20 to move in a certain direction. The movement of the second motor 20 drives the cleaning roller 22 to start rotating, thereby cleaning the lower mold 7. At the same time, the cylinder 3 drives the upper mold 6 to move towards the fixed plate 17. When the upper mold 6 enters the working area, the cleaning roller 22 on the upper side of the fixed plate 17 enters the interior of the upper mold 6. At this time, the cleaning device can start cleaning the upper mold 6. Finally, the drive motor 19 is started, and the motor 19 drives the upper cleaning roller 22 to rotate, thereby realizing the cleaning operation of the upper mold 6. The cleaning roller 22 contacts and rotates with the mold, effectively removing dirt from the surface of the mold.
[0030] Secondly, when rapid cooling of the injection-molded product is required, water pump 9 starts, drawing cooling water from water tank 8. The drawn cooling water is then sent through delivery pipe 10 into the cooling channel 11 of the lower mold 7. The mold design typically includes cooling channel 11 to ensure that water can uniformly cool the mold and the injection-molded product. The cooling water flows inside the mold, absorbing the heat generated by the mold and plastic product during the injection molding process, thus lowering the mold temperature. After heat exchange, the water flows out from the other end of cooling channel 11, enters return pipe 12, and returns to water tank 8. The returned hot water is cooled by cooler 13 in water tank 8. Cooler 13 typically uses refrigerant or other cooling media to cool the hot water to an appropriate temperature. The cooled water is then drawn back by water pump 9 and enters mold cooling channel 11, forming a closed-loop cycle that continuously maintains the mold temperature within an appropriate range, ensuring the stability of the injection molding process and product quality.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
