Description

Technical Field

[0001] The utility model relates to the technical field of release agent recovery, in particular to a device for recycling release agent. Background Art

[0002] A release agent is a functional substance between a mold and a finished product. The release agent has heat resistance and stress properties, is not easily decomposed or worn, adheres to the mold without transferring to the processed workpiece, and does not interfere with painting or other secondary processing operations.

[0003] In the existing release agent recovery device, the release agent in the recovery process is often drained through an inclined deflector. Since most deflectors are designed as U-shaped grooves with a flat bottom, this greatly increases the contact area between the release agent and the deflector during the recovery process, thereby affecting the flow rate of the release agent on the deflector. On the other hand, due to the increase in the contact area between the release agent and the deflector, more release agent will adhere to the bottom of the deflector during the recovery process. If the staff does not clean the release agent adhering to the bottom of the deflector in time after the release agent recovery work is completed, the release agent adhering to the bottom of the deflector will dry up and adhere to the bottom of the deflector, further affecting the drainage rate of the deflector when draining the release agent next time, and the actual use effect of the device is not good;

[0004] On the other hand, there are great difficulties in the current recovery of release agents. On the one hand, the chemical components of release agents are complex and difficult to separate. On the other hand, the physical and chemical properties of release agents are prone to change in the die-casting environment, and impurities such as aluminum chips and dross on the surface of die-castings are easily washed down and mixed with the release agent. This leads to the need to filter the used release agent through a filter plate before recovering the release agent. Since there are many impurities such as aluminum chips and residues mixed in the release agent, a large amount of aluminum chips and residues often accumulate on the filter plate for filtering the release agent, causing the filter plate to be blocked. If the staff cannot timely detect the blockage of the filter plate and clean the residues on the filter plate, the blocked filter plate will affect the normal recovery of the release agent, and the practical effect of the device is poor;

[0005] Moreover, during the recovery process of the release agent, due to the contact of the release agent with the mold cavity, the guide rail of the die-casting machine, and the body of the die-casting machine during use, it often contains components such as miscellaneous oil and particulate impurities. Most filter plates can only filter the particulate impurities mixed in the release agent and cannot effectively treat the miscellaneous oil. This results in the miscellaneous oil being mixed in the release agent and entering the release agent sedimentation tank for sedimentation. If the staff cannot effectively treat the miscellaneous oil mixed in the release agent, the miscellaneous oil mixed in the release agent is extremely likely to enter the next recovery process during the pumping and transportation of the release agent, affecting the recovery quality of the release agent.

[0006] For this reason, we design a demoulding agent recycling device to provide another technical solution to the above technical problems. Content of the Utility Model

Specific embodiments

[0035] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] Embodiment

[0037] Referring to Figures 1-9 , a demolding agent recycling device, including the main body 1 of the injection molding machine, a demolding agent recycling mechanism and a demolding agent utilization mechanism. The demolding agent recycling mechanism is arranged at the bottom of the main body 1 of the injection molding machine. The main body 1 of the injection molding machine is provided with a first installation groove 2 facilitating the installation of the demolding agent recycling mechanism. A sedimentation tank 3 is fixedly arranged inside the first installation groove 2. One side of the sedimentation tank 3 is respectively connected with a miscellaneous oil storage barrel 4 and a demolding agent purification barrel 5. The demolding agent utilization mechanism is arranged on one side of the demolding agent recycling mechanism and is communicated with the demolding agent purification barrel 5. The main body 1 of the injection molding machine is provided with a liquid injection port 6 for delivering the demolding agent to the sedimentation tank 3.

[0038] Through the design of the demolding agent recycling mechanism, the used demolding agent is recycled and multi-layer purified, effectively improving the purity of the demolding agent after filtration. On the other hand, one side of the sedimentation tank 3 is designed in a transparent glass shape. Through this design, the staff can observe the scraping situation of the miscellaneous oil inside the sedimentation tank 3 outside, ensuring the normal operation of the demolding agent recycling mechanism.

[0039] Referring to Figures 3-5, the demoulding agent recovery mechanism includes a diversion plate 7 inclined at the bottom of the injection molding machine body 1. A plurality of fixing rods 8 for fixing are fixedly arranged on the outer side of the diversion plate 7. The top ends of the fixing rods 8 are fixedly connected to the inner wall of the injection molding machine body 1. A transfer frame 9 matching the diversion plate 7 is arranged at the top end of the sedimentation tank 3. The diversion plate 7 is fixedly arranged on the transfer frame 9. A cleaning component for cleaning the inside of the diversion plate 7 is arranged inside the diversion plate 7;

[0040] The cleaning component includes a cleaning scraper 10 slidably arranged inside the diversion plate 7 and designed in a semi-circular shape. A magnetic block 101 for adsorbing the cleaning scraper 10 is arranged on the inner side of the top end of the diversion plate 7. Guide blocks 11 are fixedly connected to both sides of the cleaning scraper 10. A plurality of first balls 12 are rotatably connected to the bottom ends of the guide blocks 11. Guide grooves 13 matching the guide blocks 11 and the first balls 12 are formed on the diversion plate 7. One end of the guide block 11 near the outside is fixedly connected to an L-shaped control rod 14. A strip-shaped groove 15 matching the L-shaped control plate is arranged on the injection molding machine body 1. Specifically, in the present utility model, through the design of the diversion plate 7 and the transfer frame 9, the used demoulding agent is guided and collected, so that the subsequent filtering component can uniformly filter the demoulding agent, ensuring the normal operation of the demoulding agent recovery mechanism. Through the design of the cleaning component, it is convenient for the staff to clean the demoulding agent attached to the bottom of the diversion plate 7 in time after the recovery, thereby avoiding the phenomenon that the demoulding agent adheres to the bottom of the diversion plate 7 due to drying, effectively ensuring the drainage rate of the diversion plate 7 when draining the demoulding agent next time, and improving the actual use effect of the device;

[0041] It should be noted that in the present utility model, the diversion plate 7 is designed in a U-shaped tubular shape. Through this design, while ensuring the normal drainage of the demoulding agent, it avoids excessive contact between the demoulding agent and the bottom of the diversion plate 7, effectively improving the flow rate of the demoulding agent on the diversion plate 7. On the other hand, the cleaning scraper 10 is made of cast iron material that can be adsorbed by the magnetic block 101. Through this design, it is ensured that when the cleaning scraper 10 is not working, it can always be located inside the top end of the diversion plate 7, thereby avoiding the cleaning scraper 10 from affecting the diversion work of the diversion plate 7 and ensuring the normal operation of the demoulding agent recovery work. Moreover, through the design of the first balls 12, the movement resistance of the cleaning scraper 10 moving inside the diversion plate 7 is effectively reduced, effectively improving the smoothness of the cleaning scraper 10 when cleaning the diversion plate 7 and improving the practical performance of the device.

[0042] When it is necessary to clean the mold release agent attached to the deflector 7, the staff only needs to pull the L-shaped control rod 14 along the strip groove, which can drive the cleaning scraper 10 to perform a downward scraping movement in the deflector 7, so as to clean the mold release agent attached to the deflector 7. During the cleaning process, the staff can place a collection box at the end of the deflector 7 to collect the mold release agent scraped from the deflector 7. At the same time, the collection box can also not be placed, so that the mold release agent scraped from the deflector 7 directly falls on the first filter plate 20, and the staff can clean the first filter plate 20 later.

[0043] Referring to Figure 6 , a filtering component for filtering the mold release agent is provided on the bottom side of the precipitation tank 3. The filtering component includes a filtering insertion plate 16 movably inserted at the top end of the precipitation tank 3. One end of the filtering insertion plate 16 is fixedly connected with a first magnetic strip 17, and the other end of the filtering insertion plate 16 is fixedly connected with a handle 18 convenient for pulling. A first slot 19 matching the filtering insertion plate 16 and the first magnetic strip 17 is provided on the injection molding machine main body 1 and the precipitation tank 3. A first filter plate 20 and a second filter plate 21 are movably inserted on one side of the filtering insertion plate 16 close to the transfer frame 9. One end of the first filter plate 20 and the second filter plate 21 is fixedly connected with a second magnetic strip 22, and the other end of the first filter plate 20 and the second filter plate 21 is fixedly connected with a handle 23. A second slot 24 matching the second magnetic strip 22 and the handle 23 is provided on the filtering insertion plate 16;

[0044] One side of the second slot 24 is communicated with a shunt input pipe 25. The end of the shunt input pipe 25 away from the second slot 24 is communicated with a detection bottle 26. The shunt input pipe 25 is threadedly connected to the detection bottle 26 through a pipe joint. The detection bottle 26 is fixedly arranged on one side of the injection molding machine main body 1. A third filter plate 27 for filtering the mold release agent is arranged inside the detection bottle 26. An observation window 28 convenient for observation is opened on one side of the detection bottle 26. The bottom end of the detection bottle 26 is fixedly connected with a shunt output pipe 29. One end of the shunt output pipe 29 penetrates through the injection molding machine main body 1 and is communicated with the precipitation tank 3. Specifically, in the present utility model, through the design of the filtering component, while ensuring the normal filtration of impurities such as aluminum chips and scum mixed in the mold release agent, it is convenient for the staff to timely discover the blockage of the filter plate and clean it, effectively improving the practical effect of the device;

[0045] It should be noted that in the present utility model, the contact positions of the filter insert 16, the first filter plate 20 and the second filter plate 21 with the first magnetic strip 17 and the second magnetic strip 22 are made of magnetic metal materials. Through this design, the stability of the filter insert 16, the first filter plate 20 and the second filter plate 21 after placement is ensured, and unnecessary movement of the filter insert 16 under the impact of the release agent or the vibration of the machine operation is avoided. At the same time, the stability of the first filter plate 20 and the second filter plate 21 placed inside the filter insert 16 is ensured, and the phenomenon that the first filter plate 20 and the second filter plate 21 are separated from the filter insert 16 during the process of removing the filter insert 16 from the sedimentation tank 3 is avoided, thereby improving the stability during the operation of the device;

[0046] During specific use, most of the release agent filtered by the first filter plate 20 flows into the sedimentation tank 3 through the second filter plate 21, and a small part of the release agent flows into the detection bottle 26 through the shunt input pipe 25. At this time, the staff can observe the release agent flowing into the detection bottle 26 through the observation window 28. If multiple visible particles are shown in the release agent, it proves that the first filter plate 20 located at the top of the filter insert 16 is damaged and needs to be replaced. At this time, the unfiltered release agent in the detection bottle 26 can still be filtered by the third filter plate 27 and flow into the sedimentation tank 3 through the shunt output pipe 29, effectively improving the practical performance of the device.

[0047] Refer to Figures 7-9 As shown in the figure, an oil scraping assembly for scraping the miscellaneous oil inside the release agent is provided inside the sedimentation tank 3. The oil scraping assembly includes a plurality of chain wheels 30 rotatably connected to one side of the sedimentation tank 3. A chain 31 is engaged outside the plurality of chain wheels 30. A driving motor 32 for driving the chain wheel 30 is fixedly connected to the middle of one of the chain wheels 30. The driving motor 32 is fixedly arranged on the outer wall of the injection molding machine main body 1. The output end of the driving motor 32 penetrates the side walls of the injection molding machine main body 1 and the sedimentation tank 3 and is fixedly connected to the middle of the chain wheel 30. A plurality of pin shafts 33 are fixedly connected to the side of the chain 31 away from the driving motor 32. Oil scraping plates 34 for scraping the miscellaneous oil are fixedly connected to the bottom ends of the plurality of pin shafts 33. One end of the oil scraping plate 34 away from the pin shaft 33 is fixedly connected to a guiding slider 35. Ball bearings two 36 are rotatably connected to the upper and lower ends of the guiding slider 35. An annular sliding groove 37 matching the guiding slider 35 and the ball bearings two 36 is opened inside the sedimentation tank 3. The annular sliding groove 37 matches the movement track of the chain 31;

[0048] One side of the precipitation tank 3 is provided with an oil storage tank 38 that cooperates with the oil scraping plate 34. An electric cylinder 39 is embedded in the oil storage tank 38. The output end of the electric cylinder 39 penetrates through the oil storage tank 38 and is connected to an L-shaped baffle 40 for blocking the release agent. The bottom end of the oil storage tank 38 is provided with an oil delivery pipe 41 connected to the miscellaneous oil storage barrel 4. The oil inlet end of the miscellaneous oil storage barrel 4 is provided with a liquid suction pump 42 for sucking the miscellaneous oil stored in the oil storage tank 38. The oil delivery pipe 41 is communicated with the input end of the liquid suction pump 42. Specifically, in the present utility model, through the design of the oil scraping assembly, the miscellaneous oil mixed in the release agent is processed, effectively solving the influence of the miscellaneous oil following the release agent into the next recycling process on the recycling quality of the release agent, and further improving the actual use effect of the device. Through the design of the guiding slider 35, the second ball 36 and the annular chute 37, while ensuring that the oil scraping plate 34 moves in a circular motion in the precipitation tank 3, the movement resistance of the oil scraping plate 34 moving in the precipitation tank 3 is effectively reduced, making the entire oil scraping process of the oil scraping assembly smoother and effectively improving the actual use effect of the device. Through the design of the electric cylinder and the L-shaped baffle 40, in cooperation with the oil scraping plate 34, the floating oil floating on the top end inside the precipitation tank 3 is scraped off, effectively avoiding too much release agent being scraped out of the precipitation tank 3 by the oil scraping plate 34 during the scraping of the miscellaneous oil, and improving the practicability of the device;

[0049] It should be noted that in the present utility model, the oil scraping plate 34 is designed in a rhombus shape. Through this design, during the process of scraping the floating oil on the top end of the precipitation tank 3 by the oil scraping plate 34, the floating oil can be gradually pushed by the inclined surface at the top end of the oil scraping plate 34 to be higher than the liquid level height of the release agent liquid in the precipitation tank 3 and be pushed into the oil storage tank 38 by the oil scraping plate 34, completing the separation of the release agent and the floating oil. On the other hand, a liquid level sensor for detecting the liquid level height of the release agent is provided inside the precipitation tank 3, and the liquid level sensor is electrically connected to the electric cylinder 39 inside the precipitation tank 3 through a controller. Through this design, the L-shaped baffle 40 fixedly connected to the output end of the electric cylinder 39 can be adjusted accordingly according to the real-time change of the liquid level height of the release agent, so that it is always slightly higher than the liquid level height of the release agent, effectively ensuring the normal operation of the oil scraping assembly.

[0050] Refer to Figure 8 , the oil scraping assembly further includes a barrier plate 43 provided at the top end of the filtering assembly and blocking the filtering assembly. One side of the barrier plate 43 is fixedly connected to an electric cylinder 44. An installation groove 45 matching the electric cylinder 44 and the barrier plate 43 is provided inside the precipitation tank 3. Specifically, in the present utility model, through the design of the barrier plate 43, the electric cylinder and the installation groove 45 and in cooperation with the transfer frame 9, the subsequent release agent flowing into the precipitation tank 3 is blocked in a timely manner, thereby ensuring the normal precipitation of the release agent in the precipitation tank 3 and ensuring the normal operation of the release agent recycling mechanism.

[0051] When cleaning the miscellaneous oil mixed in the mold release agent, the staff starts the electric cylinder two 44 to make the baffle plate 43 extend outwards to block the mold release agent in the transfer frame 9. Then, the mold release agent is left standing in the sedimentation tank 3 for a period of time, so that the miscellaneous oil mixed in the mold release agent floats to the top of the sedimentation tank 3. Then, the staff starts the drive motor 32 to make the oil scraping plate 34 move in a circular motion in the sedimentation tank 3 and push the floating oil on the top of the sedimentation tank 3, so that it is placed in the oil storage tank 38 opened on one side of the sedimentation tank 3, and rotates multiple times to scrape the floating oil on the top of the sedimentation tank 3. Then, the drive motor 32 stops. At this time, the liquid level of the mold release agent in the sedimentation tank 3 gradually drops during the scraping of the floating oil. After the liquid level sensor inside the sedimentation tank 3 senses the drop in the liquid level, the electric cylinder one 39 is started through the controller, so that the L-shaped baffle plate 40 fixedly connected to the output end of the electric cylinder one 39 moves downwards, so that it is always slightly higher than the liquid level height of the mold release agent. Then, after the mold release agent is left standing for the second time, the staff restarts the drive motor 32 to make the oil scraping plate 34 scrape the floating oil on the top of the sedimentation tank 3 for the second time, and repeats the above operations in turn. During the operation of the oil scraping assembly, the staff can observe the scraping situation of the floating oil inside the mold release agent through the sedimentation tank 3 at any time. When the floating oil is completely scraped off, the staff controls the drive motor 32 and the electric cylinder one 39 to stop, and starts the liquid suction pump one 42 to pump the miscellaneous oil accumulated in the oil storage tank 38 into the miscellaneous oil storage barrel 4, so as to complete the cleaning of the miscellaneous oil inside the mold release agent. After the mold release agent in the sedimentation tank 3 is completely used up or all sucked into the mold release agent storage barrel 46, the staff starts the electric cylinder two 44 to drive the baffle plate 43 to retract, so that the mold release agent stored in the transfer frame 9 flows back into the sedimentation tank 3 through the filter assembly again, and the continuous recovery of the mold release agent can be completed.

[0052] Refer to Figure 1, the mold release agent utilization mechanism includes a mold release agent storage barrel 46 for storing unused mold release agent. The top of the mold release agent purification barrel 5 is fixedly connected and communicated with a second liquid suction pump 47 for sucking the mold release liquid inside the precipitation tank 3. The input end of the second liquid suction pump 47 is fixedly connected with an infusion pipe 48. The end of the infusion pipe 48 away from the second liquid suction pump 47 is communicated with the precipitation tank 3. One side of the mold release agent storage barrel 46 opposite to the mold release agent purification barrel 5 is connected by a pipeline with a two-position three-way solenoid valve 49. The output end of the two-position three-way solenoid valve 49 is connected by a pipeline with a third liquid suction pump 50. The output end of the third liquid suction pump 50 is connected by a pipeline with a spray gun 51 for spraying the mold release agent. A hook 52 for conveniently hanging the spray gun 51 is provided on the injection molding machine main body 1. Specifically, in the present utility model, through the design of the mold release agent utilization mechanism, the recycled mold release agent is rationally utilized according to the different molding qualities of the produced products, so that the device can, while meeting the demolding qualities of different products, maximize the use of the recycled mold release agent, thereby effectively reducing the production cost of the products and improving the practical performance of the device;

[0053] In the present utility model, the recycled mold release agent is used according to three different situations:

[0054] 1. Directly utilize the recycled mold release agent, which is applicable to products with relatively rough molding and low requirements for product quality.

[0055] 2. Mix the recycled mold release agent with pure mold release agent for use, which is applicable to products with certain requirements for molding quality.

[0056] 3. Do not use the recycled mold release agent, and only use unused pure mold release agent to demold the products, which is applicable to products with high requirements for demolding quality.

[0057] During specific use, the staff only needs to control the two-position three-way solenoid valve 49 to close or open the corresponding valve ports according to different product production requirements, and the third liquid suction pump 50 sucks the mold release agent liquid corresponding to the port of the two-position three-way solenoid valve 49 into the spray gun 51, and the spray gun 51 sprays it. When spraying the mold release agent on products with certain requirements for molding quality, the flow rate of the mold release agent liquid in the mold release agent storage barrel 46 and the mold release agent purification barrel 5 entering the third liquid suction pump 50 can be controlled by the two-position three-way solenoid valve 49, so as to complete the mixing between the used mold release agent and the unused mold release agent and ensure the normal use of the mold release agent utilization mechanism.

[0058] The use process of a mold release agent recycling and utilization device provided by the present utility model is as follows:

[0059] When the mold release agent recycling mechanism is working, the used mold release agent flows into the diversion plate 7 through the liquid injection port 6, and converges into the transfer frame 9 through the diversion plate 7. Then, it flows into the sedimentation tank 3 through the filter assembly arranged at the bottom of the transfer frame 9. During this process, most of the mold release agent filtered by the first filter plate 20 flows into the sedimentation tank 3 through the second filter plate 21, and a small part of the mold release agent flows into the detection bottle 26 through the shunt input pipe 25. At this time, the staff can observe the mold release agent flowing into the interior of the detection bottle 26 through the observation window 28. If multiple visible particles are shown in the mold release agent, it proves that the first filter plate 20 located at the top of the filter insertion plate 16 is damaged and needs to be replaced. At this time, the unfiltered mold release agent in the detection bottle 26 can still be filtered by the third filter plate 27 and flow into the sedimentation tank 3 through the shunt output pipe 29. When the liquid level height of the mold release agent in the sedimentation tank 3 is about to exceed the top end of the oil scraping plate 34, the staff starts the second electric cylinder 44 to make the baffle plate 43 block the subsequent flowing mold release agent, so that the mold release agent is left standing in the sedimentation tank 3 for a period of time, so that the miscellaneous oil mixed in the mold release agent floats to the top of the sedimentation tank 3. Then, the staff starts the driving motor 32 to make the oil scraping plate 34 move in a circular motion in the sedimentation tank 3 and push the floating oil on the top of the sedimentation tank 3, so that it is placed in the oil storage tank 38 opened on one side of the sedimentation tank 3, and rotates multiple times to scrape the floating oil on the top of the sedimentation tank 3. Then, the driving motor 32 stops. At this time, the liquid level of the mold release agent in the sedimentation tank 3 gradually drops during the scraping of the floating oil. After the liquid level sensor inside the sedimentation tank 3 senses the drop in the liquid level, it starts the first electric cylinder 39 through the controller, so that the L-shaped baffle plate 40 fixedly connected to the output end of the first electric cylinder 39 moves down, so that it is always slightly higher than the liquid level height of the mold release agent. Then, after the mold release agent is left standing for the second time, the staff restarts the driving motor 32 to make the oil scraping plate 34 scrape the floating oil on the top of the sedimentation tank 3 for the second time, and repeats the above operations in turn. During the operation of the oil scraping assembly, the staff can observe the scraping situation of the floating oil inside the mold release agent through the sedimentation tank 3 at any time. When the floating oil is completely scraped off, the staff controls the driving motor 32 and the first electric cylinder 39 to stop, and starts the first liquid suction pump 42 to pump the accumulated miscellaneous oil in the oil storage tank 38 into the miscellaneous oil storage barrel 4, and then the cleaning of the miscellaneous oil inside the mold release agent can be completed. After the mold release agent in the sedimentation tank 3 is completely used up or all sucked into the mold release agent storage barrel 46, the staff starts the second electric cylinder 44 to drive the baffle plate 43 to retract, so that the mold release agent stored in the transfer frame 9 flows into the sedimentation tank 3 again through the filter assembly, and then the continuous recycling of the mold release agent can be completed;

[0060] When the mold release agent utilization mechanism is working, the staff only needs to control the two-way three-way solenoid valve 49 to close or open the corresponding valve ports according to different product production requirements. Then, the liquid transfer pump III 50 sucks the mold release agent liquid corresponding to the port of the two-way three-way solenoid valve 49 into the spray gun 51, and the spray gun 51 sprays it. When spraying the mold release agent on products with certain requirements for molding quality, the flow rate of the mold release agent liquid in the mold release agent storage barrel 46 and the mold release agent purification barrel 5 entering the liquid transfer pump III 50 can be controlled by the two-way three-way solenoid valve 49, so as to complete the mixing between the used and unused mold release agents and ensure the normal use of the mold release agent utilization mechanism.
