Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and in particular to an intelligent mold release agent mixing machine. Background Technology

[0002] Release agent is a special chemical preparation applied to the surface of a mold cavity. It is sprayed onto the surface of the mold cavity to create an interface coating. This coating can adhere well to the surface of the mold cavity without reacting or sticking to the product. It can help aluminum die castings to be demolded smoothly after die casting and prevent the aluminum die castings from sticking to the mold. Therefore, release agent plays an important role in the die casting process.

[0003] To ensure the quality of mold release, the ratio of the mold release agent is particularly important. Currently, the mold release agent is often manually mixed and proportioned by on-site employees. After mixing, it is then transported to the spraying machine using a pneumatic diaphragm pump. However, manual mixing suffers from low accuracy, long time consumption, and low efficiency. Moreover, spillage and splashing are prone to occur during the mixing process, resulting in waste of raw materials. When using a pneumatic diaphragm pump to transport the mixed liquid to the spraying machine, employees need to manually turn off the pneumatic diaphragm pump when the spraying machine is not in operation, as the pneumatic diaphragm pump cannot be started and stopped automatically. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an intelligent mold release agent mixing machine that can realize the automatic mixing of mold release agents, improve the mixing efficiency, and also realize the automatic start and stop of the pneumatic diaphragm pump.

[0005] This utility model provides an intelligent mold release agent mixing machine, characterized in that it includes:

[0006] Mixing tank;

[0007] The mixing mechanism includes an inlet pipe, a water inlet pipe, a raw liquid pipe, and a proportioning pump. The inlet pipe is connected to the mixing tank and is equipped with a first valve.

The raw liquid pipe is connected to the inlet pipe through the proportioning pump and is used to quantitatively deliver raw liquid into the mixing tank.

[0008] The first draining mechanism includes a first drain pipe, a first delivery pump, a second valve, and a flow sensor. The first drain pipe is connected to the mixing tank. The first delivery pump and the second valve are installed on the first drain pipe. The flow sensor is installed inside the first drain pipe. The first draining mechanism is used to transport the mixing liquid in the mixing tank to external spraying equipment.

[0009] The controller is electrically connected to the proportional pump, the first valve, the first delivery pump, and the flow sensor.

[0010] Furthermore, the mixing mechanism also includes a raw liquid tank, the raw liquid pipe is connected to the raw liquid tank, and a first liquid level sensor for detecting the liquid level of the raw liquid is provided on the top of the raw liquid tank.

[0011] Furthermore, it also includes an alarm, which, along with the first liquid level sensor, is electrically connected to the controller.

[0012] Furthermore, it also includes a stirring mechanism, which includes a stirring rod, stirring blades and a drive motor. The stirring rod is disposed inside the mixing tank. Multiple sets of stirring blades are evenly arranged along the circumference of the outer wall of the stirring rod. One end of the stirring rod is connected to a drive motor that drives its rotation. The drive motor is electrically connected to the controller.

[0013] Furthermore, it also includes a concentration detection mechanism, which includes a concentration sensor and a second liquid level sensor disposed in the mixing tank, both of which are electrically connected to the controller.

[0014] Furthermore, it also includes a second draining mechanism, which includes a second drain pipe, a second delivery pump, and a third valve. The second drain pipe is connected to the proportioning tank, and the second delivery pump and the third valve are disposed on the second drain pipe.

[0015] Furthermore, the top of the mixing tank is also provided with a feed inlet.

[0016] Furthermore, a third liquid level sensor is disposed above the second liquid level sensor in the mixing tank, and a fourth liquid level sensor is disposed below the second liquid level sensor in the mixing tank.

[0017] Furthermore, a placement box is fixedly connected to one side of the mixing tank. The placement box is divided into an upper chamber and a lower chamber. The upper chamber is used to place the controller, and the lower chamber is used to place the mixing mechanism.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) This utility model can achieve quantitative delivery of water and raw materials by means of a proportional pump, thereby ensuring the ratio and concentration of the release agent. Compared with manual ratio, it improves the ratio accuracy and accelerates the ratio efficiency.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Please refer to Figures 1-2 An embodiment of this utility model provides an intelligent mold release agent mixing machine, including a mixing tank 1, a mixing mechanism 2, a first discharge mechanism 3, and a controller; wherein,

[0036] Mixing tank 1 has a cylindrical structure;

[0037] The proportioning mechanism 2 includes an inlet pipe 21, a water inlet pipe 22, a raw liquid pipe 23, and a proportioning pump 24. The inlet pipe 21 is connected to the proportioning tank 1, and a first valve 25 is provided on the inlet pipe 21. The water inlet pipe 22 is connected to the inlet pipe 22 through the proportioning pump 24 and is used to quantitatively deliver clean water into the proportioning tank 1. The raw liquid pipe 23 is connected to the inlet pipe 21 through the proportioning pump 24 and is used to quantitatively deliver raw liquid into the proportioning tank 1.

[0038] The first drainage mechanism 3 includes a first drainage pipe 31, a first delivery pump 32, a second valve 33, and a flow sensor 34. The first drainage pipe 31 is connected to the mixing tank 1. The first delivery pump 32 and the second valve 33 are installed on the first drainage pipe 31. The flow sensor 34 is installed inside the first drainage pipe 31. The first drainage mechanism 3 is used to transport the mixing liquid in the mixing tank 1 to the external spraying equipment.

[0039] The controller, proportional pump 24, first valve 25, first delivery pump 32 and flow sensor 34 are all electrically connected to the controller.

[0040] Specifically, the proportioning pump 24 is a commercially available dual-knob controlled proportioning pump (such as a gear metering pump), and its specific structure will not be described in detail here. One end of the water inlet pipe 21 is connected to the proportioning pump 24, and the other end is connected to the water supply device. By rotating the corresponding knob, the amount of clean water delivered to the inlet pipe 21 can be controlled. One end of the stock solution pipe 23 is connected to the proportioning pump 24, and the other end is inserted into the stock solution tank containing the stock solution. By rotating the corresponding knob, the amount of stock solution delivered to the inlet pipe 21 can be controlled. The mixture of clean water and stock solution is delivered to the mixing tank 1 through the inlet pipe 21. The proportioning pump 24 can adjust the ratio of clean water to stock solution to achieve automatic mixing of the release agent. Compared with manual mixing, this improves the mixing accuracy and efficiency. The connection methods of the inlet pipe 21, the water inlet pipe 22, and the stock solution pipe 23 to the proportioning pump 24 are all conventional and feasible connection methods in the prior art, and are not limited here.

[0041] Specifically, one end of the first drain pipe 31 is inserted into the mixing tank 1, and the other end is connected to the spraying machine to transport the mixing liquid. During transport, the second valve 33 is manually opened, allowing the mixing liquid to enter the first drain pipe 31. During this process, the flow rate in the first drain pipe 31 is detected by the flow sensor 34. When the spraying machine is performing spraying operations, if the flow rate in the first drain pipe 31 is lower than a preset value, the controller will start the first delivery pump 32, transporting the mixing liquid from the mixing tank 1 to the first drain pipe 31, ensuring timely delivery. The delivery of the prepared liquid; when the spraying machine stops working, the flow rate in the first drain pipe 31 is higher than the preset value, and the controller controls the first delivery pump 32 to stop working; the first delivery pump 32 is a pneumatic diaphragm pump. This application can automatically realize the start and stop of the first delivery pump 32 through the flow sensor 34 and the controller, avoiding manual control of the start and stop of the first delivery pump 32. When the spraying machine stops working, the first delivery pump 32 also stops working, avoiding the first delivery pump 32 from being continuously in the start state and extending the service life of the first delivery pump 32.

[0042] In a preferred embodiment, such as Figure 2 As shown, the mixing mechanism 2 also includes a raw material tank 26, with a raw material pipe 23 connected to the raw material tank 26. A first liquid level sensor 27 for detecting the liquid level of the raw material is provided on the top of the raw material tank 26. Preferably, it also includes an alarm 28, and both the alarm 28 and the first liquid level sensor 27 are electrically connected to the controller.

[0043] Specifically, the top of the stock solution tank 26 is an open structure, and a detachable lid is provided at the open end. A first liquid level sensor 27 is installed on the lid, and the detection end of the first liquid level sensor 27 is located at the bottom of the lid, which can be used to detect the liquid level of the stock solution in the stock solution tank 26. The lid also has a through hole for the stock solution pipe 23 to pass through. The stock solution pipe 23 is a flexible tube that can be inserted into the stock solution tank 26 through the through hole to transport the stock solution. This application can detect the liquid level of the stock solution in the stock solution tank 26 in real time through the first liquid level sensor 27. When the liquid level of the stock solution is lower than the preset value (that is, when the liquid level of the stock solution tank 26 is detected to be low), the first valve 25 is closed, the proportional pump 24 is stopped, the mixing operation is stopped, and the alarm 28 sounds an alarm to remind the staff to replenish the stock solution in time.

[0044] In a preferred embodiment, such as Figure 2 As shown, it also includes a stirring mechanism 4, which includes a stirring rod, stirring blades and a drive motor. The stirring rod is set inside the mixing tank 1. Multiple sets of stirring blades are evenly arranged on the outer wall of the stirring rod along its circumference. One end of the stirring rod is connected to a drive motor that drives its rotation. The drive motor is electrically connected to the controller.

[0045] Specifically, by setting the stirring mechanism 4, the original liquid and water can be fully mixed, improving the quality of the release agent. In addition, the mixing tank 1 is closed, and the stirring mechanism 4 is set inside the mixing tank 1, which can prevent the liquid from splashing to the outside and reduce the waste of the original liquid.

[0046] In a preferred embodiment, such as Figure 2 As shown, it also includes a concentration detection mechanism 5, which includes a concentration sensor 51 and a second liquid level sensor 52 installed in the mixing tank 1. Both the concentration sensor 51 and the second liquid level sensor 52 are electrically connected to the controller.

[0047] Specifically, the liquid level of the mixing solution in the mixing tank 1 is detected by the second liquid level sensor 52. When the liquid level reaches the preset value (200), the proportioning pump 24 stops working, the first valve 25 closes, and the mixing process stops. The concentration sensor 51 detects the concentration of the mixing solution. If the concentration of the mixing solution meets the preset concentration, the proportioning pump 24 starts and the first valve 25 opens to continue the mixing process. If the concentration of the mixing solution does not meet the preset value, the mixing process stops again. This application uses the concentration sensor 51 to recheck the concentration of the mixing solution, avoiding errors in the mixing concentration caused by a malfunction of the proportioning pump 24.

[0048] In a preferred embodiment, such as Figure 2 As shown, it also includes a second draining mechanism 6, which includes a second drain pipe 61, a second delivery pump 62 and a third valve 63. The second drain pipe 61 is connected to the proportioning tank 1, and the second delivery pump 62 and the third valve 63 are disposed on the second drain pipe 61.

[0049] In this embodiment, one end of the second drain pipe 61 is connected to the proportioning tank 1, and the other end is connected to the retesting tank. When the concentration detection sensor 51 detects that the concentration of the proportioning solution does not meet the preset value, the proportioning pump 24 stops working, the third valve 63 opens, and the second delivery pump 62 starts to discharge the proportioning solution in the proportioning tank 1 into the retesting tank for storage. The proportioning solution in the retesting tank is manually proportioned by the staff to make its concentration reach the preset value.

[0050] In a preferred embodiment, such as Figure 2 As shown, the top of the mixing tank 1 is also provided with a feed inlet 11.

[0051] Specifically, after the concentration of the mixing solution in the retest tank reaches the preset value, it can be transported again to the mixing tank 1 through the feed inlet 11 for storage, so that it can be transported to the spraying machine later.

[0052] In a preferred embodiment, such as Figure 2 As shown, a third liquid level sensor 12 is installed above the second liquid level sensor 52 inside the mixing tank 1, and a fourth liquid level sensor 13 is installed below the second liquid level sensor 52 inside the mixing tank 1. Both the third liquid level sensor 12 and the fourth liquid level sensor 13 are electrically connected to the controller.

[0053] Specifically, the upper limit level of the mixing solution is detected by the third liquid level sensor 12, and the lower limit level of the mixing solution is detected by the fourth liquid level sensor 13. When the mixing solution reaches the upper limit level, the first valve 25 is closed, the proportional pump 24 stops working, and the mixing solution supply is stopped. When the mixing solution reaches the lower limit level, the first valve 25 is opened, the proportional pump 24 is started, clean water and original solution are added, and the mixing process is carried out.

[0054] In a preferred embodiment, such as Figure 2 As shown, a placement box 7 is fixedly connected to one side of the proportioning tank 1. The placement box 7 is divided into an upper chamber 71 and a lower chamber 72. The upper chamber 71 is used to place the controller, and the lower chamber 72 is used to place the proportioning mechanism 2.

[0055] Specifically, the placement box 7 and the proportioning tank 1 are fixedly connected as a whole, and the bottom of the placement box 7 and the proportioning tank 1 are equipped with casters to facilitate the movement of the whole; and the placement box 7 is hinged with a door, which makes it easy to put the original liquid tank 26 into the lower chamber 72 for storage when the door is opened, resulting in a compact structure.

[0056] Working principle:

[0057] When preparing the release agent, the stock solution tank 26 containing the stock solution is placed into the lower chamber 72, and then the inlet end of the stock solution pipe 23 is inserted into the stock solution tank 26. The controller controls the first valve 25 to open and starts the proportioning pump 24. The proportioning pump 24 delivers water and stock solution quantitatively to the proportioning tank 1, realizing the automatic proportioning of the release agent. Compared with manual proportioning, the proportioning accuracy and proportioning efficiency are improved.

[0058] Furthermore, this application uses a second liquid level sensor 52 to detect the liquid level of the mixing tank 1. When the liquid level reaches a preset value (200), the concentration of the mixing liquid is detected by a concentration sensor 51. If the concentration of the mixing liquid meets the preset concentration, the mixing process continues; if the concentration of the mixing liquid does not meet the preset value, the mixing process stops. This application uses the concentration sensor 51 to recheck the concentration of the mixing liquid, avoiding errors in the mixing concentration caused by a malfunction of the proportioning pump 24.

[0059] This application connects the mixing tank 1 to the spraying machine via a first drain pipe. When the mixing liquid is being transported, the flow rate in the first drain pipe 31 is detected by the flow sensor 34. When the spraying machine is performing spraying work, if the flow rate in the first drain pipe 31 is lower than the preset value, the controller controls the first delivery pump 32 to start, so that the mixing liquid in the mixing tank 1 is transported to the first drain pipe 31, thus realizing the timely transport of the mixing liquid. When the spraying machine stops working, if the flow rate in the first drain pipe 31 is higher than the preset value, the controller controls the first delivery pump 32 to stop working. This application can automatically start and stop the first delivery pump 32 through the flow sensor 34 and the controller, avoiding manual control of the start and stop of the first delivery pump 32. Moreover, when the spraying machine stops working, the first delivery pump 32 also stops working, avoiding the first delivery pump 32 from being continuously running and extending the service life of the first delivery pump 32.
