Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold release agent proportioning technology, and relates to a mold release agent proportioning machine, especially a mold release agent recycling proportioning machine. Background Technology
[0002] To avoid waste, mold release agents after die casting are currently recycled. The recycled mold release agent undergoes filtration and other processes to remove impurities, as disclosed in Chinese patent documents such as the small mold release agent recycling device [Application No. 201721462529.0] and a novel mold release agent recycling system [Application No. 202211310593.2]. These patent documents all disclose mold release agent recycling structures. However, the recycled mold release agent loses moisture due to high temperatures, resulting in a high concentration that cannot be used directly and requires remixing. To address this, Chinese patent documents also disclose a mold release agent recycling and reuse device [Application No. 202010956971.9] and a mixing mechanism for a mold release agent recycling system [Application No. 201810453160.X]. These patents all disclose structures that utilize the recycled mold release agent for remixing and reuse. However, in practice, the amount of mold release agent inevitably decreases over time, requiring the addition of new mold release agent. The aforementioned equipment has a single mixing function and cannot meet the needs of adding new mold release agents. Existing mold release agent mixing is achieved using a hydrodynamic mixing machine. The hydrodynamic mixing machine uses water to drive a piston to extract a fixed amount of concentrated mold release agent concentrate to achieve the mixing. The piston moves back and forth to extract the concentrate, meaning that the mixing of mold release agent in the hydrodynamic mixing machine is not continuous, resulting in low efficiency. Furthermore, the accuracy of extraction by the piston is low, making it difficult to achieve the optimal mold release agent ratio. The presence of solidified particles in the concentrated mold release agent concentrate can cause wear on the piston, leading to a relatively short service life for the hydrodynamic mixing machine. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a release agent recycling and proportioning machine. The technical problem solved by this invention is to provide a proportioning method for two release agents and to obtain an accurate proportion of the release agent.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A mold release agent recycling and proportioning machine includes a storage tank, a pneumatic diaphragm pump connected to the storage tank, and a controller. The machine further includes a raw liquid proportioning component and a recycled liquid proportioning component. The raw liquid proportioning component includes a flow meter, a flow meter, a water pipe, a raw liquid pipe, and a raw liquid proportioning pipe. The water pipe is equipped with a solenoid valve. The raw liquid pipe is equipped with an electric pump. The inlet of the flow meter is connected to the water pipe. The inlet of the flow meter is connected to the raw liquid pipe. The outlets of both the flow meter and the flow meter are connected to the raw liquid proportioning pipe. The raw liquid proportioning pipe is connected to the storage tank. Meter 1, flow meter 2, solenoid valve, and electric pump 1 are all electrically connected to the controller; the recovered liquid proportioning assembly includes flow meter 3, flow meter 4, recovered liquid pipe, raw liquid pipe 2, and recovered liquid proportioning pipe. Electric pump 2 is connected to raw liquid pipe 2, and pneumatic diaphragm pump 2 is connected to recovered liquid pipe. The inlet of flow meter 3 is connected to the recovered liquid pipe, the inlet of flow meter 4 is connected to raw liquid pipe 2, and the outlets of flow meter 3 and flow meter 4 are both connected to the recovered liquid proportioning pipe. The recovered liquid proportioning pipe is connected to the storage tank. Flow meter 3, flow meter 4, electric pump 2, and pneumatic diaphragm pump 2 are all electrically connected to the controller.
[0006] When in use, the tap water pipe is connected to the faucet to provide tap water. Both the first and second raw liquid pipes are connected to the raw liquid tank containing the concentrated raw liquid of the release agent. The recovery liquid pipe is connected to the recovery tank containing the recovered release agent liquid.
[0007] When using the original liquid proportioning component, the solenoid valve opens, tap water flows through flow meter one, electric pump one opens, and the concentrated mold release agent concentrate flows through flow meter two. When the tap water flowing through flow meter one reaches the set value, the controller will control the solenoid valve to close. When the concentrated mold release agent concentrate flowing through flow meter two reaches the set value, the controller will control electric pump one to close, thus achieving precise proportioning of the mold release agent. When using the recovered liquid proportioning component, both electric pump two and pneumatic diaphragm pump two open. The concentrated mold release agent concentrate flows through flow meter four, and the recovered liquid flows through flow meter three. When the concentrated mold release agent concentrate flowing through flow meter four reaches the set value, the controller will control electric pump two to close. When the recovered liquid flowing through flow meter three reaches the set value, the controller will control pneumatic diaphragm pump two to close, thus achieving precise proportioning of the mold release agent.
[0008] The mixing unit can provide mold release agent diluted with tap water via a stock solution mixing component, or mold release agent diluted with recycled liquid via a recycled liquid mixing component. The supply of mold release agent can be flexibly adjusted according to actual conditions. Flow meters can precisely control the flow rate. Flow meters one, two, three, and four can precisely control the flow rate of the liquid passing through them, thus precisely controlling the ratio of mold release agent concentrate to tap water and the ratio of recycled liquid to mold release agent concentrate, resulting in a more accurate mold release agent mix. The flow meters can continuously supply a set amount of liquid, enabling faster and more efficient delivery of mold release agent.
[0009] In the aforementioned mold release agent recycling and mixing machine, a filter is connected to the tap water pipe. The filter can filter out impurities and particles in the tap water.
[0010] In the aforementioned mold release agent recycling and mixing machine, a second filter is connected to the recovery liquid pipe. The mold release agent recovery liquid is drawn from the recovery tank by a pneumatic diaphragm pump, and the second filter can filter out impurity particles in the mold release agent recovery liquid.
[0011] In the aforementioned mold release agent recycling and proportioning machine, a one-way valve is provided between the flow meter two and the original liquid proportioning pipe. The one-way valve one can open in one direction to one end of the original liquid proportioning pipe. Since the proportion of tap water is relatively large, the one-way valve one allows the concentrated mold release agent original liquid after passing through the flow meter two to enter the original liquid proportioning pipe, while preventing the tap water in the original liquid proportioning pipe from entering.
[0012] In the aforementioned mold release agent recycling and proportioning machine, a one-way valve is provided between the flow meter four and the recovery liquid proportioning pipe. The one-way valve two can open in one direction to one end of the recovery liquid proportioning pipe. Since the proportion of the recovery liquid is relatively large, the one-way valve two allows the concentrated mold release agent stock solution after passing through the flow meter four to enter the recovery liquid proportioning pipe, while preventing the recovery liquid located in the stock solution proportioning pipe from entering.
[0013] In the aforementioned mold release agent recycling and mixing machine, the storage tank is equipped with a partition that divides the tank into a finished product chamber and a mixing chamber. A connecting hole is provided at the lower end of the partition, linking the finished product chamber and the mixing chamber. Both the raw liquid mixing pipe and the recycled liquid mixing pipe are connected to the mixing chamber. The outlets of the raw liquid mixing pipe and the recycled liquid mixing pipe are located at the upper end of the mixing chamber. The pneumatic diaphragm pump is connected to the finished product chamber. The mold release agent flowing out of the raw liquid mixing pipe and the recycled liquid mixing pipe is not completely mixed. Further mixing in the mixing chamber ensures complete mixing. The mold release agent entering the mixing chamber initially resides at the top of the mixing chamber. After the mold release agent in the finished product chamber is used, the completely mixed mold release agent located at the bottom of the mixing chamber is replenished into the finished product chamber through the connecting hole.
[0014] In the aforementioned mold release agent recycling and mixing machine, both the finished product cavity and the mixing cavity are equipped with ultraviolet disinfection lamps. These ultraviolet disinfection lamps continuously disinfect the mold release agent in both the finished product cavity and the mixing cavity.
[0015] In the aforementioned mold release agent recycling and mixing machine, air blowing pipes are fixed in both the finished product chamber and the mixing chamber. The air inlet of the air blowing pipe is connected to an air pump, and the air outlet of the air blowing pipe is located at the lower end of the corresponding finished product chamber and mixing chamber. By blowing air into the finished product chamber and the mixing chamber, the air blowing pipes agitate the mold release agent through air bubbles, ensuring that the mold release agent remains completely mixed.
[0016] In the above-mentioned mold release agent recycling and proportioning machine, a liquid level gauge is fixed in the finished product cavity.
[0017] Compared with existing technologies, this mold release agent recycling and proportioning machine has the following advantages:
[0018] 1. It can simultaneously provide mold release agent diluted with tap water and mold release agent diluted with recycled liquid and concentrated mold release agent, and can flexibly adjust the supply of mold release agent.
[0019] 2. The flow meter allows for more precise and efficient mixing of the release agent, resulting in a longer service life. Attached Figure Description

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0025] like Figures 1 to 3 As shown, the mold release agent recycling and proportioning machine includes a chassis 1, a controller, a storage tank 2 installed in the chassis 1, a water pump 26 connected to the storage tank 2, a raw liquid proportioning component, and a recycled liquid proportioning component. In this application, the controller is a PLC controller.
[0026] like Figure 3 As shown, the stock solution mixing assembly includes flow meter 3, flow meter 31, water pipe 32, stock solution pipe 34, and stock solution mixing pipe 35. Water pipe 32 is connected to faucet 7 to supply tap water. A solenoid valve 38 and a filter 33 are installed on water pipe 32. Stock solution pipe 34 is connected to stock solution tank 5 containing concentrated release agent stock solution. An electric pump 36 is installed on stock solution pipe 34. The inlet of flow meter 3 is connected to water pipe 32. The inlet of flow meter 2 31 is connected to the raw liquid pipe 1 34. The outlets of flow meter 1 3 and flow meter 2 31 are both connected to the raw liquid mixing pipe 35. A one-way valve 1 37 is provided between flow meter 2 31 and raw liquid mixing pipe 35. The one-way valve 1 37 can be opened to one end of the raw liquid mixing pipe 35 in one direction. The raw liquid mixing pipe 35 is connected to the storage tank 2. Flow meter 1 3, flow meter 2 31, solenoid valve 38 and electric pump 1 36 are all electrically connected to the controller.
[0027] like Figure 3 As shown, the recovery liquid proportioning assembly includes flow meter 3 (4), flow meter 41 (41), recovery liquid pipe 42, raw liquid pipe 2 (45), and recovery liquid proportioning pipe 46. Raw liquid pipe 2 (45) is connected to the raw liquid tank 5 containing concentrated raw release agent solution, and an electric pump 2 (47) is connected to raw liquid pipe 2 (45). Recovery liquid pipe 42 is connected to the recovery tank 6 containing recovered release agent solution, and a water pump 2 (43) and a filter 2 (44) are connected to recovery liquid pipe 42. The inlet of flow meter 3 (4) is connected to the recovery liquid pipe 42. The inlet of flow meter 41 is connected to the raw liquid pipe 45, and the outlets of flow meter 41 and flow meter 3 are both connected to the recovery liquid proportioning pipe 46. A one-way valve 48 is provided between flow meter 41 and recovery liquid proportioning pipe 46. The one-way valve 48 can open to one end of recovery liquid proportioning pipe 46 in one direction. Recovery liquid proportioning pipe 46 is connected to storage tank 2. Flow meter 41, electric pump 47 and water pump 43 are all electrically connected to the controller.
[0028] like Figures 1 to 3As shown, the storage tank 2 is equipped with a partition 21, which divides the storage tank 2 into a finished product chamber 22 and a mixing chamber 23. A level gauge is fixed in the finished product chamber 22. Both the finished product chamber 22 and the mixing chamber 23 are equipped with ultraviolet disinfection lamps 24 and air blowing pipes 25. The air inlet of the air blowing pipe 25 is connected to an air pump, and the air outlet of the air blowing pipe 25 is located at the lower end of the corresponding finished product chamber 22 and mixing chamber 23. A connecting hole 211 is opened at the lower end of the partition 21 to connect the finished product chamber 22 and the mixing chamber 23. The raw liquid proportioning pipe 35 and the recovered liquid proportioning pipe 46 are both connected to the mixing chamber 23. The outlet of the raw liquid proportioning pipe 35 and the outlet of the recovered liquid proportioning pipe 46 are located at the upper end of the mixing chamber 23. A pneumatic diaphragm pump is connected to the finished product chamber 22. The solutions in the original liquid mixing tube 35 and the recovered liquid mixing tube 46 will initially mix as they flow through. The outflowing release agent is not completely mixed. It will be further mixed by agitation with air bubbles in the mixing chamber 23, so that the release agent is completely mixed. The release agent entering the mixing chamber 23 is initially located above the mixing chamber 23. After the release agent in the finished product chamber 22 is used, the release agent located below the mixing chamber 23 that is completely mixed is replenished into the finished product chamber 22 through the connecting hole 211.
[0029] A float sensor is installed in the recovery tank 6, and the float sensor is electrically connected to the controller. When the liquid level in the storage tank 2 is lower than the set liquid level, the level gauge sends a signal to the controller, at which point the release agent needs to be added to the storage tank 2. The controller first determines the amount of recovered liquid in the recovery tank 6 based on the signal from the float sensor. If the liquid level in the recovery tank 6 is lower than the set liquid level, the amount of recovered liquid in the recovery tank 6 is small, and the float sensor sends a signal to the controller. The controller then controls the original liquid proportioning component to work, and at this time, the release agent concentrated original liquid and the release agent mixed with tap water are used to replenish the release agent in the storage tank 2. If the liquid level in the recovery tank 6 is higher than the set liquid level, the amount of recovered liquid in the recovery tank 6 is large, and the float sensor sends a signal to the controller. The controller then controls the recovery liquid proportioning component to work, and at this time, the release agent concentrated original liquid and the release agent mixed with the recovered liquid are used to replenish the release agent in the storage tank 2.
[0030] The flow meter 3 and solenoid valve 38 work together to control the proportion of tap water. The flow meter 31 and electric pump 36 and the flow meter 41 and electric pump 47 work together to control the proportion of release agent concentrate. The flow meter 4 and water pump 43 work together to control the proportion of recovered liquid.
[0031] Since the concentrated release agent solution has a relatively small proportion compared to water or recycled liquid, in order to achieve rapid mixing of the concentrated release agent solution, it is added in small amounts multiple times during actual use.
[0032] The flow control of flow meter 2 (31), flow meter 3 (4), and flow meter 4 (41) is achieved through the controller. The specific flow setting can be adjusted through the control panel of the controller, which is convenient and accurate. Flow meter 1 (3), flow meter 2 (31), flow meter 3 (4), flow meter 4 (41), and electric pump are existing products on the market. Water pump 1 (26) and water pump 2 (43) both adopt pneumatic diaphragm pumps.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
