Description

A mold release agent mixing and stirring device and a nano-dispersion process Technical Field

[0001] This invention belongs to the field of mold release agent stirring and preparation technology, specifically relating to a mold release agent stirring and mixing device and a nano-dispersion process. Background Technology

[0002] Release agents are functional substances that lie between the mold and the finished product, and are widely used in metal die casting, rubber products, and composite material processing. With the rapid development of nanotechnology, adding nanoscale fillers (such as nano-graphite, nano-boron nitride, or modified nanoparticles) to release agents to improve their lubricity, high-temperature resistance, and release efficiency has become a mainstream trend in the industry.

[0003] Existing mold release agent stirring devices typically employ traditional mechanical blade rotation stirring. However, when preparing nanoscale mold release agents, traditional stirring methods have the following significant drawbacks: 1. Particle agglomeration: Particles have extremely high specific surface energy. After entering the base oil or aqueous phase, the rotational shear force of the blades alone is insufficient to break the van der Waals forces between their molecules, leading to easy particle agglomeration and preventing true nanoscale dispersion.

[0004] 2. Low dispersion efficiency and dead zones: The flow field formed by the traditional agitator in the vessel is relatively fixed. For materials at the bottom and edge of the vessel, the kinetic energy transfer is weak, which easily creates dead zones and results in uneven particle size distribution of the final product.

[0005] 3. Lack of multi-dimensional kinetic energy coupling: Existing technologies mostly involve single rotational motion, lacking vertical physical impact. When processing release agent formulations with high viscosity or high solids content, simple rotational stirring is insufficient to induce cavitation effects and high-frequency turbulence in the material, thus limiting further improvement in dispersion performance.

[0006] In view of this, this solution was developed. Summary of the Invention

A first one-way valve is provided; a second flow channel is used to connect the bottom of the first piston cylinder and the oil storage chamber, and a second one-way valve is provided on the second flow channel; a third flow channel is used to connect the bottom of the second piston cylinder and the oil storage chamber, and an electromagnetic switch valve is provided; the opening area of ​​the third flow channel at the bottom of the second piston cylinder occupies one-third or more of the bottom surface area of ​​the second piston cylinder; the diameter of the first piston rod is larger than the diameter of the second piston rod; the vessel body has connecting blocks on at least two horizontal sides; the two lifting components are respectively adapted to the two connecting blocks; the connecting blocks form through holes extending vertically; the first piston rod extends out of the circumference of the first piston cylinder to form a support platform; the first piston rod extends out of the through hole; a spring is provided between the support platform and the connecting block; the spring is sleeved on the first piston rod; the driving body is used to drive the second piston rod to move up and down.

[0009] Furthermore, the vessel body includes a lid and a body. The lid covers the opening on the body. A drive integration box is provided on the lid. A spiral stirring paddle is provided inside the body. The spiral stirring paddle extends through the lid into the drive integration box. A drive gear set is provided inside the drive integration box. A driven gear is located on the circumferential surface of the spiral stirring paddle inside the drive integration box. A drive motor is installed on the side wall of the drive integration box. The drive motor drives the driven gear to rotate through the drive gear set.

[0010] Furthermore, an upwardly extending extension ring is formed at the upper opening of the vessel body, and an outwardly extending first connecting ring is formed at the port of the extension ring. The vessel cover is fitted to the first connecting ring and connected by bolts.

[0011] Furthermore, a feed pipe is formed on the vessel lid, the feed pipe including a feed connecting pipe and a feed sliding pipe, the inner diameter of the feed connecting pipe is equal to the outer diameter of the feed sliding pipe, the outer circumferential surface of the feed sliding pipe is formed with three layers of annular grooves, and Teflon rings, Glycol rings and Teflon rings are arranged sequentially in the three layers of annular grooves, the feed connecting pipe is set on the vessel lid, and the feed sliding pipe is used to connect to the hopper.

[0012] Furthermore, a discharge pipe is formed on the lower surface of the reactor body. The discharge pipe includes a discharge connecting pipe and a discharge sliding pipe. The inner diameter of the discharge connecting pipe is equal to the outer diameter of the discharge sliding pipe. Three annular grooves are formed on the outer circumference of the discharge sliding pipe. Teflon rings, Glycol rings, and Teflon rings are arranged sequentially in the three annular grooves. The discharge connecting pipe is connected to the finished product bin, and the discharge sliding pipe is located on the lower surface of the reactor body.

[0013] Furthermore, the number of lifting components is four, which are arranged at intervals in a ring around the periphery of the vessel body, and the number of connecting blocks is four, which are arranged at intervals in a ring around the periphery of the vessel body.

[0014] A nano-dispersion process for a release agent, employing a release agent mixing and stirring device, includes the following steps: S1, first, adding 50-70 parts of base oil and 5-15 parts of film-forming agent into the reactor through the feed pipe; then, adding 3-8 parts of emulsifier and 1-5 parts of stabilizer in proportion; finally, slowly adding 20-40 parts of deionized water and the remaining rust inhibitor and defoamer; S2, starting the drive motor, and the spiral agitator performs preliminary mixing and stirring of the above mixture, so that the film-forming agent and emulsifier are evenly distributed in the base oil; S3, after the preliminary low-speed mixing and stirring is completed, the spiral agitator enters... A second stirring is performed, with the stirring speed exceeding that of the initial mixing. While the spiral stirring paddle continues stirring, the upper and lower oscillation components of the device are activated. The drive body reciprocates by pressing the second piston rod, causing the first piston rod to rise and move the vessel body upward at a low speed. After the first piston rod moves to the designated height, the electromagnetic switch valve releases pressure, and the first piston rod resets, causing the vessel body to move downward and form an up-and-down oscillation. Through mechanical shock waves, the film-forming agent undergoes nanoscale breakage under the action of the emulsifier. S4. After dispersion is completed, the oscillation components and drive motor are turned off, and the finished product is discharged to the finished product silo through the discharge pipe on the lower surface of the vessel body.

[0018] Compared with existing technologies, this invention has the following beneficial effects: 1. It achieves the physical coupling of multi-dimensional shearing and high-energy oscillation, significantly improving dispersion uniformity: By combining the horizontal shearing force of the spiral stirring paddle with the high-frequency oscillating shock wave in the vertical direction of the vessel, the single flow field mode inside the vessel is changed. The cavitation effect and strong turbulence generated by vertical oscillation can effectively break the van der Waals forces between nanofillers (such as nano-graphite and film-forming agents), inhibit particle agglomeration, and make the release agent particle size distribution narrower and more stable.

[0019] 2. A unique dual-piston hydraulic drive structure enables efficient conversion of kinetic energy and rhythm control: This invention utilizes the area difference between the first and second piston rods to generate hydraulic gain. Combined with the drive unit and electromagnetic switching valve, it can precisely control the "slow rise and rapid fall" or high-frequency pulse-like oscillation rhythm of the reactor body. This asymmetric acceleration change further enhances the inertial impact within the material, greatly improving emulsification and dispersion efficiency and shortening the preparation cycle.

[0020] 3. Completely eliminates dead zones in mixing, ensuring consistent material quality: The entire vessel moves up and down with the hydraulic components, ensuring that materials in traditionally dead zones such as the bottom and inner edges of the vessel receive sufficient kinetic energy. Combined with the axial flow guidance of the spiral agitator, it achieves mixing throughout the entire area without dead zones, ensuring a high degree of consistency in the physicochemical properties of each batch of release agent.

[0021] 4. Innovative telescopic pipeline sealing structure, balancing flexible vibration with high reliability: The sleeve design between the inlet and outlet sliding pipes and the connecting pipe, combined with a sealing assembly consisting of Teflon rings and Glycol rings, effectively solves the problems of easy fatigue damage of hoses and easy leakage of joints in traditional devices during vibration. This structure not only adapts to high-frequency vibration but also has extremely high wear resistance and corrosion resistance, significantly extending the service life of the equipment.

Detailed Implementation

[0024] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0025] As shown in Figures 1-5, this embodiment provides a mold release agent mixing device, including a vessel body 1 and an upper and lower oscillation assembly. The vessel body 1 includes a vessel cover 11 and a vessel body 12. The vessel cover 11 covers the opening on the vessel body 12. A drive integration box is provided on the vessel cover 11. A spiral stirring paddle is provided inside the vessel body 12. The spiral stirring paddle passes through the vessel cover 11 and extends into the drive integration box. A drive gear set is provided inside the drive integration box. The spiral stirring paddle has a driven gear on its circumferential surface inside the drive integration box. A drive motor is installed on the side wall of the drive integration box. The drive motor drives the driven gear to rotate through the drive gear set.

[0026] The connection structure between the lid 11 and the body 12 is as follows: an upwardly extending ring 111 is formed at the upper opening of the body 12, and an outwardly extending first connecting ring is formed at the port of the extension ring 111. The lid 11 fits into the first connecting ring and is connected by bolts.

[0027] The pipeline connection is as follows: a feed pipeline is formed on the vessel lid 11, which includes a feed connecting pipe 112 and a feed sliding pipe 113. The inner diameter of the feed connecting pipe 112 is equal to the outer diameter of the feed sliding pipe 113. Three annular grooves are formed on the outer circumference of the feed sliding pipe 113. Teflon ring 3, Glycol ring 4 and Teflon ring 3 are arranged in sequence in the three annular grooves.

[0028] A discharge pipe is formed on the lower surface of the reactor body 12. The discharge pipe includes a discharge connecting pipe 121 and a discharge sliding pipe 122. The inner diameter of the discharge connecting pipe 121 is equal to the outer diameter of the discharge sliding pipe 122. Three annular grooves are formed on the outer circumference of the discharge sliding pipe 122. Teflon ring 3, Glycol ring 4 and Teflon ring 5 are arranged in sequence in the three annular grooves. The discharge connecting pipe 121 is connected to the finished product bin. The discharge sliding pipe 122 is located on the lower surface of the reactor body 12.

[0029] The innovative telescopic pipeline sealing structure balances flexible vibration with high reliability: the sleeve design between the inlet and outlet sliding pipes 122 and the connecting pipe, combined with the sealing assembly consisting of Teflon rings 3 and Glycol rings 4, effectively solves the problems of easy fatigue damage of hoses and easy leakage of joints in traditional devices during vibration. This structure not only adapts to high-frequency vibration, but also has extremely high wear resistance and corrosion resistance, significantly extending the service life of the equipment.

[0030] The vessel body has four annularly spaced connecting blocks 13 on its circumference for connecting to the upper and lower oscillation components.

[0031] The up-and-down oscillation assembly is used to drive the vessel 1 to oscillate up and down during the stirring process. Specifically, the up-and-down oscillation assembly includes four lifting components 2, which correspond to four connecting blocks 13 respectively. The lifting component 2 includes a base 21, an oil storage shell 22, a first piston rod 23 and a second piston rod 24, and a driving body. A first piston cylinder 28 and a second piston cylinder 29 are formed on the base 21. The first piston rod 23 and the second piston rod 24 are respectively disposed in the first piston cylinder 28 and the second piston cylinder 29 with their ends facing upward. The oil storage shell 22 is sleeved on the outer wall of the first piston cylinder 28. An oil storage chamber is formed between the oil storage shell 22 and the base 21 and the outer shell of the first piston rod 23.

[0032] The base 21 has a first flow channel 211, a second flow channel 212, and a third flow channel 213. The first flow channel 211 connects the bottom of the first piston cylinder 28 and the cylinder body of the second piston cylinder 29, and a first one-way valve 25 is provided on the first flow channel 211. The flow direction of the first one-way valve 25 is from the second piston cylinder 29 to the first piston cylinder 28. The second flow channel 212 is used to connect the bottom of the first piston cylinder 28 and the oil storage chamber, and a second one-way valve 26 is provided on the second flow channel 212. The third flow channel 213 is used to connect the bottom of the second piston cylinder 29 and the oil storage chamber, and an electromagnetic switch valve 27 is provided. The opening area of ​​the third flow channel 213 at the bottom of the second piston cylinder 29 accounts for one-third or more of the bottom surface area of ​​the second piston cylinder 29. Specifically, there are three third flow channels 213, and three electromagnetic switch valves 27 corresponding to the three flow channels. The opening area of ​​the third flow channel 213 at the bottom of the second piston cylinder 29 accounts for one-third of the bottom surface area of ​​the second piston cylinder 29. The diameter of the first piston rod 23 is larger than the diameter of the second piston rod 24. In this embodiment, the diameter of the first piston rod 23 is twice the diameter of the second piston rod 24.

[0033] The lifting component 2 is adapted to the connecting block 13. The connecting block 13 has a through hole running vertically through it. The first piston rod 23 extends out of the circumference of the first piston cylinder 28 and forms a support platform 231. The first piston rod 23 extends out of the through hole. A spring 232 is provided between the support platform 231 and the connecting block 13. The spring 232 is sleeved on the first piston rod 23. The driving body is used to drive the second piston rod 24 to move up and down. The driving body is a hydraulic cylinder. A special bracket is provided for installing the driving body. The driving body is located above the second piston rod 24.

[0034] This embodiment also provides a nano-dispersion process for a release agent, which is made using the above-mentioned release agent stirring and mixing device, including the following steps: S1, firstly, add 50-70 parts of base oil and 5-15 parts of film-forming agent into the reactor body 1 through the feed pipe; then add 3-8 parts of emulsifier and 1-5 parts of stabilizer in proportion; finally, slowly add 20-40 parts of deionized water and the remaining rust inhibitor and defoamer; in step S1, the weight ratio of base oil to deionized water is 1.25-3.5:1, and the preferred weight ratio is 1.25:1.

[0035] S2. Start the drive motor and the spiral agitator performs preliminary mixing and stirring of the above mixture to make the film-forming agent and emulsifier evenly distributed in the base oil. In step S2, the drive motor drives the spiral agitator to rotate at 300-600 r / min and the stirring time is 10-20 min to make the materials initially mixed to form an emulsion precursor. In this embodiment, 500 r / min is used and the stirring time is 20 min.

[0036] S3. After the initial low-speed mixing is completed, the spiral agitator performs secondary mixing. The secondary mixing speed is greater than the initial mixing speed. While the spiral agitator continues to mix, the upper and lower oscillation components of the device are activated. The drive body presses the second piston rod 24 back and forth, causing the first piston rod 23 to rise and drive the vessel body 1 to move upward at a low speed. After the first piston rod 23 moves to the designated height, the electromagnetic switch valve 27 releases pressure, and the first piston rod 23 is depressurized and reset, causing the vessel body 1 to move downward and form an upper and lower oscillation. The film-forming agent is broken down into nanoscale particles by mechanical shock waves under the action of the emulsifier. S4. After dispersion is completed, the oscillation components and drive motor are turned off, and the finished product is discharged to the finished product silo through the discharge pipe on the lower surface of the vessel body 12.

[0037] This solution combines the horizontal shear force of the spiral agitator with the high-frequency oscillating shock wave in the vertical direction of the vessel body 1, thereby altering the single flow field pattern within the vessel body 1. The cavitation effect and strong turbulence generated by the vertical oscillation effectively break the van der Waals forces between nanofillers (such as nano-graphite and film-forming agents), inhibiting particle agglomeration and resulting in a narrower particle size distribution and higher stability of the release agent.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
