Description

Technical Field

[0001] This utility model belongs to the technical field of powder metallurgy machinery and equipment, specifically relating to a release agent application device for metallurgical equipment. Background Technology

[0002] In the production process of existing powder metallurgy equipment, mold release agents are required. Mold release agents are chemical additives that are mainly used to form a thin film on the surface of the mold, thereby reducing friction and facilitating product demolding. At the same time, they can increase the surface smoothness of the molded object and prevent mold sticking. They are widely used in industrial fields that require the use of molds, such as metal die casting, polyurethane foam and elastomers, glass fiber reinforced plastics, and injection molding of thermoplastic plastics.

[0003] There are two main methods for using mold release agents: one is to mix the mold release agent into the raw material, which then precipitates onto the product surface during pressing, acting as a lubricant during demolding. The advantage of this method is that it allows for large-scale automated production, but the disadvantages are that it adds a raw material mixing step, and residual mold release agent inside the product can affect its performance and purity. The other method is to spray the mold release agent before loading the mold. This method avoids the mold release agent mixing into the product, but in actual use, unevenly atomized mold release agent can leave stains on the product surface, and a large amount of mold release agent escapes into the air during spraying, polluting equipment and posing a health hazard to operators.

[0004] In summary, there is a need to design a release agent application device to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a release agent application device for metallurgical equipment, which solves the technical problems in the prior art where the release agent is mixed into the raw materials and the release agent is sprayed before the mold is loaded, thus affecting the release quality.

[0006] The technical solution adopted by this utility model is a metallurgical equipment release agent application device, including a mounting base, a rotary cylinder mounted on the top of the mounting base, a cylinder mounting seat fixed to the top of the rotary cylinder, a second lifting cylinder mounted on the cylinder mounting seat, a cantilever connected to the telescopic end of the second lifting cylinder, a sponge clamp connected to the end of the cantilever away from the second lifting cylinder, a sponge a clamped at the bottom of the sponge clamp, and a solution dipping and draining device provided at the bottom of the sponge a.

[0013] The sponge clip is made of a porous metal plate or a porous plastic plate.

[0014] The sponge clip uses an elastic sleeve made of silicone or rubber.

[0015] The beneficial effects of this utility model are:

[0016] This invention improves the water absorption performance of the sponge by designing a sponge structure. The linkage between the first lifting cylinder, the second lifting cylinder, and the two sponges enables the sponge to be dipped and squeezed dry.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1

[0022] like Figure 1As shown, the metallurgical equipment release agent application device disclosed in this embodiment includes a mounting base 11. A rotary cylinder 9 is mounted on the top of the mounting base 11. A cylinder mounting seat 8 is fixedly connected to the top of the rotary cylinder 9. A second lifting cylinder 7 is mounted on the cylinder mounting seat 8. A cantilever 6 is connected to the telescopic end of the second lifting cylinder 7. A sponge clamp 1 is connected to the end of the cantilever 6 away from the second lifting cylinder 7. A sponge a is clamped at the bottom of the sponge clamp 1. A solution dipping and draining device is provided at the bottom of the sponge a.

[0023] In this embodiment, the sponge a clamped at the bottom of the sponge clamp 1 is used to perform the final coating task after interacting with the solution dipping and draining device. The solution dipping and draining device is located directly below the sponge clamp 1 and sponge a in the initial state of the cylinder 9. The lower end of the lifting cylinder 7 is fixed to the rotary cylinder 9 through the cylinder mounting seat 8, and the upper end is connected to the cantilever 6 to realize the action of dipping the solution and coating. Specifically, the rotation of the rotary cylinder 9 drives the lifting cylinder 7, the cantilever 6, and the sponge clamp 1 to rotate, so that after the sponge a is dipped, it is rotated above the mold to be coated.

[0024] Example 2

[0025] The metallurgical equipment release agent application device disclosed in this embodiment includes a mounting base 11. A rotary cylinder 9 is mounted on the top of the mounting base 11. A cylinder mounting seat 8 is fixed to the top of the rotary cylinder 9. A second lifting cylinder 7 is mounted on the cylinder mounting seat 8. A cantilever 6 is connected to the telescopic end of the second lifting cylinder 7. A sponge clamp 1 is connected to the end of the cantilever 6 away from the second lifting cylinder 7. A sponge a is clamped at the bottom of the sponge clamp 1. A solution dipping and draining device is provided at the bottom of the sponge a. The solution dipping and draining device includes a solution box 4 set at the bottom of the sponge a. A lifting groove 3 is provided between the solution box 4 and the sponge a. A sponge b is provided, and a lifting trough 3 is connected to a first lifting cylinder 5. The lifting trough 3 achieves the function of draining water from the sponge by the rising of the lifting cylinder 5 and the falling of the lifting cylinder 7. The lifting trough 3 drives the sponge b inside it to fall through the lifting cylinder 5 to achieve the function of the sponge dipping in the solution. Several through holes are evenly opened on the bottom wall of the lifting trough 3. When the first lifting cylinder 5 falls, the solution in the solution box 4 enters the lifting trough 3 through the through holes and further enters the sponge b to achieve dipping. Afterwards, the first lifting cylinder 5 rises and the second lifting cylinder 7 falls, the sponge a and the sponge b are squeezed, and the squeezed solution returns to the solution box 4 through the through holes.

[0026] In this embodiment, the lifting cylinder 5 descends, driving the lifting tank 3 and the sponge b inside it to descend below the liquid surface of the solution box 4. The sponge b absorbs the solution, and then the lifting cylinder 5 rises while the sponge b waits. The lifting cylinder 7 descends from the initial position of the rotary cylinder 9, causing the sponge a on the sponge clamp 1 to descend and contact the sponge b in the lifting tank 3, absorbing the solution. Excess release agent is squeezed out by the sponge a and sponge b. The lifting cylinder 7 rises, and the rotary cylinder 9 rotates 90°, causing the sponge clamp 1 and the sponge a on it to move directly above the mold cavity and align with the mold cavity. The lifting cylinder 7 descends, and the sponge 2 on the sponge clamp 1 enters the mold cavity to apply the release agent. The lifting cylinder 7 rises, and the rotary cylinder 9 returns to its original position, completing the entire release agent application process.

[0027] Example 3

[0028] The metallurgical equipment release agent application device disclosed in this embodiment includes a mounting base 11, a rotary cylinder 9 mounted on the top of the mounting base 11, a cylinder mounting seat 8 fixedly connected to the top of the rotary cylinder 9, a second lifting cylinder 7 mounted on the cylinder mounting seat 8, a cantilever 6 connected to the telescopic end of the second lifting cylinder 7, a sponge clamp 1 connected to the end of the cantilever 6 away from the second lifting cylinder 7, a sponge a clamped at the bottom of the sponge clamp 1, and a solution dipping and draining device provided at the bottom of the sponge a; wherein, a buffer spring 10 is connected between the cylinder mounting seat 8 and the rotary cylinder 9, the buffer spring 10 is fixed on the cylinder mounting seat 8, and its function is to buffer the impact force of the rotary cylinder and reduce the solution on the sponge 2 from spilling out due to inertia.

[0029] Example 4

[0030] The metallurgical equipment release agent application device disclosed in this embodiment includes a mounting base 11. A rotary cylinder 9 is mounted on the top of the mounting base 11. A cylinder mounting seat 8 is fixed to the top of the rotary cylinder 9. A second lifting cylinder 7 is mounted on the cylinder mounting seat 8. A cantilever 6 is connected to the telescopic end of the second lifting cylinder 7. A sponge clamp 1 is connected to the end of the cantilever 6 away from the second lifting cylinder 7. A sponge a is clamped at the bottom of the sponge clamp 1. A solution dipping and draining device is provided at the bottom of the sponge a. The solution dipping and draining device includes a solution box 4 set at the bottom of the sponge a. A lifting groove 3 is provided between the solution box 4 and the sponge a. A sponge b is provided in the lifting groove 3. A first lifting cylinder 5 is connected to the lifting groove 3. Several through holes are evenly opened on the bottom wall of the lifting groove 3. A buffer spring 10 is connected between the cylinder mounting seat 8 and the rotary cylinder 9.

[0031] Preferably, both sponge a and sponge b are coated with a polyvinyl alcohol (PVA) coating. In this invention, sponge 2 includes sponge a and sponge b. The surface properties of sponge 2 have a significant impact on its water absorption performance. By making the surface of sponge 2 hydrophilic, the contact angle between water and the surface of sponge 2 can be reduced, making it easier for water to spread on the surface and thus easier to penetrate the pores inside sponge 2. Conversely, if the surface of sponge 2 is hydrophobic, water will form droplets on the surface, making it difficult to penetrate the sponge. Specifically, a hydrophilic coating, such as a polyvinyl alcohol (PVA) coating, is applied to the surface of sponge 2. PVA has good hydrophilicity and film-forming properties; after being applied to the surface of sponge 2, it can improve the surface properties of sponge 2 and enhance its water absorption performance. The thickness of the coating also needs to be reasonably controlled; if it is too thick, it may clog the pores and affect the water absorption performance. Generally, a coating thickness between a few micrometers and tens of micrometers is more suitable.

[0032] Alternatively, sponges a and b can be internally layered, with a porous polyester fiber mesh between adjacent sides. For the thicker sponge 2, this layered structure prevents water from creating "preferred channels" during penetration, thus avoiding uneven water absorption. The layered structure allows water to be redistributed within each layer, much like a multi-layer filtration system, where each layer regulates the water flow, resulting in more uniform absorption. Specifically, sponge 2 can be layered to a certain thickness (e.g., 5-10 mm per layer), with a permeable separating layer (e.g., a porous polyester fiber mesh with a porosity of approximately 30%-50%) between adjacent layers. The separating layer allows for slow water penetration while preventing direct contact between the upper and lower sponge layers, thus preventing the formation of localized rapid absorption channels.

[0033] Alternatively, the sponge clip 1 can be made of a porous metal plate or a porous plastic plate; a clamping material with a porous structure, such as a porous metal plate or a porous plastic plate, can be selected. The pores of these materials allow water to pass through freely, ensuring that all parts of the sponge a can come into contact with the water source. When water is supplied from below or the side, the sponge clip 1 will not obstruct the flow of water, thus creating conditions for the sponge a to absorb water evenly.

[0034] Alternatively, the sponge clip 1 can be made of elastic sleeves made of silicone or rubber. Elastic clamping materials, such as silicone or rubber clamps, can be used. These materials can adaptively adjust to the shape and size of the sponge a, applying uniform pressure to the sponge a during clamping and preventing excessive local deformation that could affect its absorbency. Simultaneously, the friction between the elastic material and the sponge a helps maintain its stable position, preventing displacement during absorption. For block-shaped sponges, elastic sleeves made of silicone can be used to tightly wrap the sponge. For cylindrical sponges, ring clamps made of rubber can be used to apply pressure from the circumference of the sponge, fixing it in the appropriate position.
