Description

Technical Field

[0001] The present invention relates to the technical field of composite material processing and manufacturing, in particular to a multi-purpose mold platform device for up and down temperature regulation. Background Art

[0002] In the field of preparing biomimetic materials for humanoid robots, particularly in the mold forming process involving waterborne polyurethane and silicone composite materials, there is currently a lack of professional, standardized mold platform devices to ensure product quality and achieve standardized production. The non-specialized tooling commonly used in existing technologies, such as stainless steel trays and iron pans, has significant drawbacks, resulting in severe material waste, poor product quality, and limited production efficiency, specifically in the following aspects:

[0003] 1. Difficulty in controlling thickness and flatness: The bottom of tooling (such as trays and iron pans) is inherently uneven and cannot meet the standard thickness and flatness requirements of the material process. Furthermore, the tooling structure is insufficiently strong (for example, the wall thickness is only about 3mm), which can easily cause warping and deformation during use, resulting in an uneven surface of the product that cannot meet the flatness requirements of the process. Furthermore, existing tooling is difficult to demold, resulting in surface cracking, delamination, and incomplete shape of the product, significantly increasing the scrap rate.

[0004] 2. Glue overflow: Existing tooling cannot effectively support the preparation of double-sided bionic materials. When attempting to use a stainless steel plate and stainless steel pallet for double-sided pressing, glue overflow is prone to occur. This is because the natural downward pressure is provided by non-standardized counterweights such as iron blocks, iron rods, and wooden boards. During this uncontrollable and uneven downward pressure, liquid bionic material can overflow from the gap between the steel plate and the pallet, enveloping the counterweight. Bubbles are also prone to occur. Tray deformation and a lack of effective venting can trap bubbles within the materials or at their interfaces, resulting in poor product bonding.

[0005] In summary, the mold platform device in the prior art has the problems of liquid biomimetic material overflow and difficulty in demoulding. Summary of the Invention

[0006] The present invention provides a multi-purpose mold platform device capable of adjusting temperature up and down, which can solve the problems of liquid biomimetic material overflow and demoulding difficulty in the mold platform device in the prior art.

[0007] A multi-purpose mold platform device with up and down temperature adjustment comprises a mold platform and an upper cover plate. A mold cavity is formed on the top of the mold platform. The upper cover plate is arranged in the mold cavity. Exhaust notches are formed at the four corners of the upper cover plate.

[0008] Two steel rod assemblies are arranged opposite to each other on the outside of the mold platform, each of the steel rod assemblies includes a first steel rod and steel rod connecting members respectively arranged at the left and right ends of the first steel rod, and an end of the steel rod connecting member away from the first steel rod extends to the outside of the mold platform;

[0009] The first steel rod is provided with two first threaded holes, each of which is provided with a first screw rod, and the lower end of the first screw rod is provided with a screw slot steel plate, the bottom of the screw slot steel plate is connected to the upper cover plate, and the first screw rod is rotatably provided on the top of the screw slot steel plate;

[0010] A groove is provided in the center of the top of the upper cover plate, and a spirit level is provided in the groove.

[0011] Furthermore, a plurality of circular mounting holes are provided at the lower end of the side surface of the mold platform, and a temperature control device is provided in the circular mounting holes.

[0012] Furthermore, the temperature control device is an electric heating pipe or a circulating water pipe.

[0013] Furthermore, a scale mark is provided at a position corresponding to the exhaust notch in the mold cavity.

[0014] Furthermore, each of the steel rod connectors includes a second steel rod and a third steel rod that are fixedly connected;

[0015] The two second steel rods are respectively arranged at the left end and the right end of the bottom of the first steel rod;

[0016] The two third steel rods are respectively arranged at the left end and the right end of the first steel rod;

[0017] One end of the third steel rod away from the first steel rod is arranged outside the mold platform.

[0018] Furthermore, the third steel rod is fixed to the outside of the mold platform by means of bolt connection.

[0019] Furthermore, a fixing nut is provided at the upper end of the outer portion of the first screw.

[0020] Furthermore, the screw slot steel plate is fixed to the top of the upper cover plate by screw connection.

[0021] Furthermore, the bottom of the upper cover plate and the inner surface of the mold cavity are both provided with Teflon coating.

[0022] Furthermore, an adjustment base is provided around the bottom of the mold platform;

[0023] The adjusting base includes an adjusting foot and a second screw, and the adjusting foot is provided with an adjusting thread groove that matches the second screw;

[0024] The outer lower end of the second screw is fitted in the adjusting thread groove, and the top of the second screw is connected to the mold platform.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention provides a multi-purpose mold platform device with up and down temperature adjustment. A mold cavity is opened on the mold platform for mold forming, and an upper cover plate is arranged in the mold cavity. A steel rod assembly is arranged on the top of the upper cover plate to play a pressing role, which effectively solves the systemic defects of existing non-standard tooling (such as stainless steel trays and iron pots) in the preparation of water-based polyurethane / silicone composite bionic materials. Specifically: First, the natural downward pressure method relying on non-standard and uncontrollable dead weight of iron blocks, iron rods, wooden boards, etc. in the prior art is abandoned. By rotating the first screw to drive the screw slot steel plate to descend, the upper cover plate is driven to apply precise, controllable and uniform downward pressure to the bionic material in the mold cavity. Through this improvement, a large amount of glue overflow can be eliminated and uniform thickness can be ensured; second, the integrated high-efficiency exhaust design significantly improves The internal quality of the product is improved by specially opening exhaust notches at the four corners of the upper cover. During the pressing process, the exhaust notches provide clear exhaust channels, allowing the liquid bionic material to be discharged smoothly, avoiding the problem of bubbles trapped on the surface or inside the material due to tray deformation and no exhaust position in the existing technology; thirdly, the demoulding process is optimized to greatly reduce the scrap rate. By rotating the first screw in the opposite direction, the upper cover can be easily and smoothly lifted off the surface of the solidified material. This design avoids the need to laboriously clean up the sticking counterweights (such as iron blocks and wooden boards wrapped in overflowed glue) during demoulding of traditional tooling and damage to the product caused by forced separation. The smooth and controllable demoulding process greatly reduces the risk of cracking, delamination, and damage to the shape of the product surface during the demoulding process, effectively reducing the scrap rate.

[0036] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0037] In the field of preparing biomimetic materials for humanoid robots, particularly in the mold forming process involving waterborne polyurethane and silicone composite materials, there is currently a lack of professional, standardized mold platform devices to ensure product quality and achieve standardized production. The non-specialized tooling commonly used in existing technologies, such as stainless steel trays and iron pans, has significant drawbacks, resulting in severe material waste, poor product quality, and limited production efficiency, specifically in the following aspects:

[0038] 1. Poor surface quality and demolding properties: Existing stainless steel trays have a high degree of roughness due to the lack of special polishing and material treatment. Water-based polyurethane is highly sticky on these surfaces, making demolding difficult. This can lead to surface cracking, delamination, and incomplete shapes, significantly increasing the scrap rate.

[0039] 2. Difficulty in controlling thickness and flatness: The bottom of the tooling (such as trays and iron pots) is not flat, which cannot meet the standard thickness and flatness requirements of the material process; and the tooling structure is not strong enough (such as the wall thickness is only about 3mm), which is prone to warping and deformation during use, resulting in an uneven surface of the product, which cannot meet the flatness required by the process.

[0040] 3. Double-sided molding process is difficult to implement: Existing tooling cannot effectively support the preparation requirements of double-sided bionic materials. When trying to use a combination of stainless steel plates and stainless steel pallets for double-sided pressing, glue overflow is prone to occur. That is, relying on non-standardized counterweights such as iron blocks, iron rods, and wooden boards to provide natural downward pressure, the pressure is uncontrollable and uneven. During the downward pressing process, liquid bionic material will overflow from the gap between the steel plate and the pallet, wrapping the counterweight. Bubble problems are also prone to occur. That is, the deformation of the pallet and the lack of an effective exhaust design cause bubbles to be trapped inside the material or at the interface, resulting in poor product bonding. It is also easy to cause demolding and cleaning damage. That is, after curing, the product is severely adhered to the tooling and the wrapped counterweight, making demolding extremely difficult. The cleaning process is very easy to pull and damage the shape and surface of the product, further increasing the scrap rate. In addition, the pressure of the natural downward pressing method is uncontrollable and uneven, which directly leads to uneven thickness of the product and cannot meet quality inspection requirements.

[0041] 4. Production efficiency bottleneck: Existing pallet-type tooling is limited by its structural characteristics and cannot integrate preheating processes. The long material curing time has become a key bottleneck restricting production efficiency.

[0042] In summary, the mold platform device in the prior art has the problems of overflow of liquid biomimetic material and difficulty in demoulding.

[0043] Based on the above content, the present invention provides a multi-purpose mold platform device with up and down temperature adjustment, which is used to solve the systemic defects of the mold platform device in the prior art in product quality (surface defects, uneven thickness, poor flatness, bubbles, high scrap rate), process implementation (difficult double-sided molding, poor demolding) and production efficiency (lack of preheating, long curing time), so as to achieve high-quality, high-efficiency and standardized preparation of bionic materials.

[0044] like Figures 1 to 7 As shown, the present invention provides a multi-purpose mold platform device for adjusting temperature up and down, comprising a mold platform 1 and an upper cover plate 4. A mold cavity 101 is formed on the top of the mold platform 1. The upper cover plate 4 is disposed in the mold cavity 101. Exhaust notches 41 are formed at the four corners of the upper cover plate 4.

[0045] The multi-purpose mold platform device with up and down temperature adjustment includes a mold platform 1 and an upper cover plate 4. The mold cavity 101 opened on the top of the mold platform 1 is used to accommodate the bionic material, and the upper cover plate 4 can be adaptively placed in the cavity 101 for pressing and curing the material; in addition, exhaust notches 41 are opened at the four corners of the upper cover plate 4, that is, when the upper cover plate 4 is placed in the mold cavity 101 on the mold platform 1, exhaust notches exist at the four corners of the upper cover plate 4 and the inner wall of the mold cavity 101, that is, formed by the exhaust notches 41. During the pressing process, the air inside the liquid bionic material and at the interface is orderly guided and smoothly discharged through the exhaust notches 41;

[0046] Two steel rod assemblies 100 are disposed opposite each other on the outside of the mold platform 1. Each steel rod assembly 100 includes a first steel rod 16 and steel rod connectors 17 disposed at the left and right ends of the first steel rod 16, respectively. An end of the steel rod connector 17 away from the first steel rod 16 extends to the outside of the mold platform 1.

[0047] The first steel rod 16 has two first threaded holes 161 formed therein. A first screw 162 is disposed in each of the first threaded holes 161. A screw slot steel plate 20 is disposed at the lower end of the first screw 162. The bottom of the screw slot steel plate 20 is connected to the upper cover plate 4, and the first screw 162 is rotatably disposed on the top of the screw slot steel plate 20.

[0048] In the multi-purpose mold platform device with up and down adjustable temperature control, a mold cavity 101 is provided on the top of the mold platform 1 for accommodating bionic materials, and the upper cover plate 4 can be adaptably placed in the mold cavity 101 for pressing and curing, and exhaust notches 41 are provided at its four corners for directional exhaust; and two oppositely arranged steel rod assemblies 100 are symmetrically arranged on the outside of the mold platform 1. In the steel rod assembly 100, the first steel rod 16 serves as the core load-bearing and transmission beam, and two first threaded holes 161 are provided on it. The steel rod connecting member 17 is fixed to the left and right ends of the first steel rod 16 and extends to the outside of the mold platform 1 to provide stable support and operating space. The first screw 162 is screwed into the first threaded hole 161, and its lower end is connected to the screw slot steel plate 20. The bottom of the screw slot steel plate 20 is connected to the upper cover plate 4. The first screw 162 is rotatably provided on the top of the screw slot steel plate 20 to form a precision transmission pair;

[0049] This multi-purpose mold platform device with up and down temperature control realizes precise and controllable lifting and lowering of the upper cover plate 4 through screw drive, combines exhaust and temperature control functions, and has the following advantages:

[0050] First, high-precision, uniform and controllable pressing is achieved, and overflowing glue and uneven thickness are completely eradicated; specifically, the pressing operation process is as follows: rotating the first screw 162 → driving the screw slot steel plate 20 to move precisely in the vertical direction → driving the upper cover plate 4 to apply evenly distributed downward pressure to the material in the mold cavity 101; adopting this device, the original counterweights such as iron blocks, iron rods, and wooden boards are abandoned, and the problem of large-scale overflow of liquid bionic materials from the gaps due to uncontrollable and uneven pressure in the background technology is eliminated from the root, achieving zero tool packaging and zero material waste, and double-sided synchronous screw drive (double-sided steel rod assembly 100 + double screws on each side) provides extremely stable, symmetrical, and fine-tunable downward pressure, ensuring that the upper cover plate 4 is pressed down in parallel, completely solving the problem of uneven thickness of products caused by natural downward pressure in the existing technology, so that the thickness tolerance of the product strictly meets the process and inspection standards;

[0051] Secondly, it can achieve non-destructive demoulding, effectively reducing the scrap rate. Specifically, the demoulding process is as follows: reverse rotation of the first screw 162 → driving the screw slot steel plate 20 and the upper cover plate 4 to lift steadily and synchronously → vertical separation from the cured product. The use of this device can eliminate the tedious step of cleaning the sticking counterweight. The operation only requires rotating the first screw 162. The vertical and stable lifting force provided by the first screw 162 completely avoids the surface tearing, delamination, and shape damage of the product caused by forced separation or cleaning in the background art. It also protects the integrity of the product to the greatest extent, significantly improving the yield rate.

[0052] Third, the device is highly strong and deformation-resistant. The double-sided steel rod assembly 100 forms a sturdy gantry frame, with the steel rod connector 17 extending to the exterior of the mold platform 1 to provide strong support. The first steel rod 16 serves as a highly rigid crossbeam, and the screw-steel plate rigid connection transmits precise force. The device exhibits high bending stiffness and maintains morphological stability under long-term use and pressing loads. Furthermore, the stable mold platform 1, the deformation-resistant upper cover plate 4, and the uniform, controllable pressing all work together to ensure that the product surface consistently meets the high flatness process requirements.

[0053] Fourth, the integrated exhaust and temperature control functions can effectively eliminate bubbles. That is, under controllable compression, the gas is discharged in an orderly manner through the four corner exhaust notches 41, completely eliminating bubble entrapment and improving internal quality.

[0054] In summary, the present invention provides a multi-purpose mold platform device with up and down temperature adjustment, which realizes high-precision control of the pressing force and demolding force during the molding process of liquid bionic materials through the "double-sided steel rod-multiple screws-rigid connection" transmission structure. This structure not only solves the process problems such as glue overflow, uneven thickness, demolding damage, and tooling deformation in the background technology, but also combines exhaust and temperature control to achieve a qualitative leap in product quality (precision, flatness, and defect-free), production efficiency (fast demolding, shortened curing), and equipment durability (anti-deformation).

[0055] like Figures 1 to 7 As shown, in some embodiments of the present invention, a groove 37 is provided in the center of the top of the upper cover plate 4, and a level 38 is provided in the groove 37;

[0056] Through this horizontal calibration system (i.e., the spirit level 38), the operator monitors the horizontal state of the upper cover plate 4 in real time through the spirit level 38 to ensure that the reference surface is absolutely horizontal before pressing; it eliminates the local pressure unevenness caused by the tilt of the cover plate from the root, so that the thickness uniformity of the product is improved. In addition, even if there is micro-deformation of the mold platform 1 (such as long-term thermal stress), it can be dynamically compensated by adjusting the screw to ensure absolute parallelism throughout the pressing process.

[0057] like Figures 1 to 7 As shown, in some embodiments of the present invention, the screw groove steel plate 20 is fixed to the top of the upper cover plate 4 by screw connection, that is, the screw groove steel plate 20 is fixed to the top of the upper cover plate 4 by connecting screws 22;

[0058] Specifically, second threaded holes are opened around the top surface of the screw slot steel plate 20, and connecting screws 22 are arranged in the second threaded holes. A connecting thread groove 401 that matches the connecting screws 22 is opened on the top of the screw slot steel plate 20;

[0059] The screw-grooved steel plate 20 is secured to the top of the upper cover plate 4 via connecting screws 22. Specifically, second threaded holes are defined around the top surface of the screw-grooved steel plate 20, each fitted with connecting screws 22. Corresponding connecting threaded grooves 401 are defined on the top of the upper cover plate 4. During assembly, the connecting screws 22 pass through the second threaded holes and screw into the connecting threaded grooves 401 on the top of the upper cover plate 4, thereby securing the upper cover plate 4.

[0060] like Figures 1 to 7 As shown, in some embodiments of the present invention, a nameplate slot 39 is further provided on the top of the upper cover plate 4 , and the nameplate slot 39 is used to place a company or product identification font plate.

[0061] like Figures 1 to 7 As shown, in some embodiments of the present invention, a plurality of mounting holes 103 are provided at the lower end of the side of the mold platform 1, and a temperature control device is provided in the mounting hole 103;

[0062] The temperature control device is an electric heating pipe or a circulating water pipe;

[0063] The temperature control device is preferably a circulating water pipe, which can be connected to an external circulating water device. The circulating water device can provide circulating water of different temperatures for the circulating water pipe, so that the circulating water in the circulating water pipe can be used for material preheating, water temperature machine heating and cooling needs;

[0064] Specifically, the temperature control device is integrated into the mold platform 1, which can achieve preheating and precise temperature control, significantly shorten the curing time, and solve the bottleneck of production efficiency.

[0065] like Figures 1 to 7 As shown, in some embodiments of the present invention, a scale mark is provided at the position corresponding to the exhaust notch 41 in the mold cavity 101;

[0066] A scale mark is provided, which works in conjunction with the spirit level 38 and the two steel rod assemblies 100 to accurately achieve thickness control. That is, a scale mark is laser-etched at a key location on the inner wall of the mold cavity 101 (directly below the exhaust notch 41), forming a thickness scale system. This solves the industry problem of uneven product thickness, repeated adjustments, and high scrap rates caused by the lack of a thickness benchmark in the background art.

[0067] In addition, the operator can directly read the pressing thickness of the liquid bionic material through the scale marking, replacing the traditional lag mode of "post-curing detection" to achieve real-time visualization of the pressing thickness; for areas around the exhaust notch 41 where thickness deviations are prone to occur (due to the flow characteristics of the material), the monitoring points are accurately located and adjustments are made in advance.

[0068] like Figures 1 to 7 As shown, in some embodiments of the present invention, each steel rod connector 17 includes a second steel rod 18 and a third steel rod 19 that are fixedly connected;

[0069] Two second steel rods 18 are respectively provided at the left and right ends of the bottom of the first steel rod 16;

[0070] Two third steel rods 19 are respectively provided at the left end and the right end of the first steel rod 16;

[0071] One end of the third steel rod 19 away from the first steel rod 16 is disposed outside the mold platform 1;

[0072] In this arrangement, two second steel rods 18 are respectively provided at the left and right ends of the bottom of the first steel rod 16. During the installation process, their bottoms are provided at the top edge of the mold platform 1 to play an auxiliary support role without interfering with the pressing of the upper cover plate 4.

[0073] The two third steel rods 19 are respectively arranged at the left end and the right end of the first steel rod 16. During the installation process, the two third steel rods 19 are located outside the mold platform 1, which facilitates the installation of the third steel rods 19 to the mold platform 1 without interfering with the pressing of the upper cover plate 4.

[0074] like Figures 1 to 7 As shown, in some embodiments of the present invention, the third steel rod 19 is fixed to the outside of the mold platform 1 by bolt connection;

[0075] Specifically, at least two third threaded holes 191 are formed on the third steel rod 19, and steel rod screws 192 are fitted in the third threaded holes 191. The mold platform 1 is provided with an assembly thread groove 108 that matches the steel rod screws 192.

[0076] The third steel rod 19 is secured to the mold platform 1 via steel rod screws 192. Specifically, two third threaded holes 191 are defined in the third steel rod 19, each fitted with steel rod screws 192. Corresponding mounting thread grooves 108 are defined in the mold platform 1. During assembly, the steel rod screws 192 pass through the third threaded holes 191 and screw into the mounting thread grooves 108 in the mold platform 1, thereby securing the third steel rod 19.

[0077] like Figures 1 to 7 As shown, in some embodiments of the present invention, a fixing nut 163 is provided at the upper end of the outer portion of the first screw rod 162;

[0078] The fixing nut 163 can be fixedly disposed on the outside of the first screw rod 162 and can be externally connected to an adjustable wrench to facilitate rotation adjustment of the first screw rod 162 .

[0079] like Figures 1 to 7 As shown, in some embodiments of the present invention, the bottom of the upper cover plate 4 and the inner surface of the mold cavity 101 are both provided with a Teflon coating; specifically, the bottom of the upper cover plate 4 and the inner surface of the mold cavity 101 are polished and then coated with the Teflon coating, thereby ensuring the flatness of the bottom of the upper cover plate 4 and the inner surface of the mold cavity 101, thereby ensuring the flatness of the prepared bionic material;

[0080] The thickness of the Teflon coating is about 0.5 mm;

[0081] Teflon has a low surface energy, which makes it difficult for biomimetic materials to adhere firmly to its surface. This effectively prevents biomimetic materials (such as silicone, polyurethane, biopolymers, or composite materials containing complex fillers) from adhering to the mold surface during the curing or molding process. After molding, even biomimetic parts with complex structures, fine textures (such as those imitating lotus leaf microstructures, shark skin shield scales, etc.), or flexibility and fragility can be removed from the mold more easily and completely, greatly reducing the difficulty of demolding and the risk of damage. This is crucial for protecting biomimetic structures.

[0082] In addition, the lubricity and non-stick properties of the Teflon coating significantly reduce physical friction and pulling damage to the mold cavity surface and the delicate structures on the bionic components during demolding. This means that smooth demolding avoids tearing, deformation, or surface residue caused by adhesion.

[0083] The non-stick property makes it difficult for residual material to adhere to the mold surface. When cleaning the mold, the cured residue is easier to remove, usually just by wiping or using a mild detergent;

[0084] Teflon can withstand continuous operating temperatures up to approximately 260°C (higher for short periods of time), making it suitable for biomimetic material processes that require heat curing or molding. Its performance is stable at this temperature and it will not decompose or lose its non-stick properties.

[0085] Combining the aforementioned advantages (easy demolding, structural protection, good surface quality, and reduced contamination), the bottom of the upper cover plate 4 and the inner surface of the mold cavity 101 are both coated with Teflon. This significantly reduces the scrap rate caused by demolding difficulties, component damage, or surface defects, thereby improving production yield and economic benefits. This is particularly important for high-value bionic products.

[0086] like Figures 1 to 7 As shown, in some embodiments of the present invention, an adjustment base 102 is further provided around the bottom of the mold platform 1;

[0087] The adjustment base 102 includes an adjustment foot 103 and a second screw 104. The adjustment foot 103 is provided with an adjustment thread groove 107 that matches the second screw 104.

[0088] The outer lower end of the second screw 104 is fitted into the adjusting thread groove 107 , and the top of the second screw 104 is connected to the mold platform 1 ;

[0089] By installing adjustment bases 102 around the bottom of the mold platform and using the adjustment thread grooves 107 on the adjustment feet 103 to mate with the threads of the second screw 104, the operator can precisely rotate the second screw 104. This allows for precise and reliable fine-tuning of the overall height and local levelness of the mold platform 1. This function is crucial for ensuring mold installation accuracy, mold clamping precision, and final product quality.

[0090] The adjustment base 102 serves as the key connection between the platform and the ground (or foundation). Its core structure, the adjustment foot 103, provides a stable support point. By transmitting the supporting force through the second screw 104 screwed into the adjustment thread groove 107, the entire adjustment system can firmly support the mold platform 1 and its load, while maintaining a stable position after adjustment, effectively resisting vibration and load changes during operation.

[0091] The adjustment mechanism is simple in design, primarily consisting of an adjustment foot 103 and a second screw 104 connected by a threaded pair (adjustment thread groove 107). The threaded transmission principle is clear, and the adjustment action (rotating the screw) is intuitive and easy to perform. Platform leveling can be accomplished without complex tools, improving the efficiency of equipment installation and maintenance.

[0092] The top of the second screw 104 is directly connected to the bottom of the mold platform 1, and the second screw 104 is rotatably mounted on the bottom of the mold platform 1. This direct connection ensures that the adjustment force (lifting / lowering) generated by the rotating screw can be efficiently and losslessly transmitted to the mold platform body, providing a structural guarantee for achieving precise position control of the platform.

[0093] This adjustable base design gives the mold platform precise height and level adjustment capabilities, providing stable and lockable support. Its simple and reliable structure, easy operation, and effective transmission of adjustment force lay a solid foundation for accurate mold installation, stable operation and product quality control.

[0094] like Figures 1 to 7 As shown, in some embodiments of the present invention, handles 402 are fixedly installed at the left and right ends of the top of the upper cover plate 4;

[0095] The handle 402 can facilitate taking the upper cover plate 4 .

[0096] like Figures 1 to 7 As shown, in some embodiments of the present invention, an adjusting nut 105 is further provided on the outside of the second screw 104;

[0097] The adjusting nut 105 can be fixedly sleeved on the outside of the second screw rod 104, so as to facilitate the rotation of the second screw rod 104 by using an adjustable wrench.

[0098] The specific operating steps of the multi-purpose mold platform device for adjusting temperature up and down are as follows:

[0099] Step 1: spray double-bond terminated waterborne polyurethane into the mold cavity 101 of the upper cover plate 4 and the mold platform 1;

[0100] Step 2: Turn on the temperature control device 106 on the mold platform 1 to preheat and dry the mold to obtain a polyurethane layer;

[0101] Step 3, spraying a platinum catalyst onto the surface of the obtained polyurethane layer;

[0102] Step 4: Mix component A and component B of the two-component silicone rubber evenly and pour them into the mold cavity 101;

[0103] Step 5: Connect and secure the upper cover plate 4 to the screw slot steel plates 20 on the two steel rod assemblies 100. Take the handle 402 and move the upper cover plate 4 and the two steel rod assemblies 100 onto the mold platform 1 so that the upper cover plate 4 is located in the mold cavity 101 inside the mold platform 1. Secure the third steel rod 19 of the two steel rod assemblies 100 to the outside of the mold platform 1.

[0104] In addition, the upper cover plate 4 is coated with a Teflon coating downward;

[0105] Step 6: Use a socket wrench to rotate the fixing nut 163 counterclockwise to drive the first screw 162 to rotate, so that the upper cover plate 4 slowly descends along the inner wall of the mold cavity 101;

[0106] In addition, during the adjustment of the first screw 162, by observing the scale of the level 38, the levelness of the pressing surface of the upper cover plate 4 and the biomimetic material during the pressing process can be observed, thereby ensuring the flatness of the product after curing;

[0107] Step 7: While the first screw 162 is rotating counterclockwise and pressing downward, the degree of pressing downward can be determined by observing the scale marks provided at the positions of the venting notches 41 in the mold cavity 101. Since there are four venting notches 41, there are also four scale marks. By measuring and observing the thickness scale marks, the thickness of the product required by different processes can be prepared.

[0108] Step 8: While ensuring that the spirit level is in a horizontal state, when the thickness required by the process is reached, stop rotating the first screw 162 and wait for the material to solidify;

[0109] Step 9: After the material solidifies, use a socket wrench to rotate the fixing nut 163 clockwise to drive the first screw 162 to rotate, so that the upper cover plate 4 slowly rises along the inner wall of the mold cavity 101. After the upper cover plate 4 is separated from the product, the connection between the third steel rod 19 of the two steel rod assemblies 100 and the mold platform 1 is released. By taking the handle 402, the upper cover plate 4 and the two steel rod assemblies 100 are removed from the mold platform 1;

[0110] The cured composite material is then taken out from the mold cavity 101 to complete the mold platform production step.

[0111] The present invention provides a multi-purpose mold platform device with up and down temperature adjustment, which is used to solve the systemic defects of the mold platform devices in the prior art in terms of product quality (surface defects, uneven thickness, poor flatness, bubbles, high scrap rate), process implementation (difficult double-sided molding, poor demoulding) and production efficiency (lack of preheating, long curing time), so as to achieve high-quality, high-efficiency and standardized preparation of bionic materials.
