Description

Technical Field

[0001] The utility model relates to the technical field of food processing molds, in particular to a cheese forming mold with a composite silicone demoulding sheet. Background Art

[0002] Cheese is highly sought after in the food market. The forming process is crucial in its production, requiring the use of molds to shape the liquid cheese into a specific shape. Demolding, a crucial step after forming, directly impacts the cheese's overall appearance, product quality, and production efficiency.

[0003] A search revealed a utility model patent, "Pastry Forming Mold with Ejection Demolding Structure," with publication number CN220422929U (authorization announcement date February 2, 2024). This solution utilizes an edge separation structure (square partitions, longitudinal rods, wedges, etc.) and an ejection structure (an electric push rod driving a bottom plate) to achieve pastry demolding. However, this solution targets dry and hard pastries, allowing for slight friction during demolding. However, its rigid ejection structure, when used on soft, moist cheeses (especially soft or semi-hard cheeses), can easily cause the cheese to tear or stick due to rigid contact, failing to meet the cheese's high requirements for non-destructive demolding.

[0004] In addition, the patent "A Residue-Free Bean Dissolving Demolding Device" with publication number CN220044880U (authorization announcement date November 21, 2023) uses a pressure-pushing mold pin to push the molten beans for demolding. However, the molten beans are loose in texture and small in volume, and the demolding force required is low. The cheese has a dense texture and a moist surface, and the push of the mold pin can easily cause local extrusion deformation, which is also not suitable for cheese demolding scenarios.

[0005] Currently, traditional cheese molds mostly use a single silicone release sheet or a rigid metal sheet. While these sheets can assist in demolding through elastic deformation, the surface of the silicone sheet still has a certain degree of adhesion, which can easily lead to cheese residue accumulation after long-term use, making cleaning and maintenance difficult. Rigid metal sheets, on the other hand, lack elasticity and are unable to adapt to the deformation compensation required for cheese lifting and demolding, which can easily lead to uneven demolding or surface damage. While some improvement proposals have introduced elastic demolding structures, they have not fully considered material composite optimization (such as the synergy between low surface adhesion and matrix elasticity) and structural stability (such as the coordination of guide and fixing components), resulting in room for improvement in demolding efficiency and cheese integrity.

[0006] In summary, the demoulding structures for food in the existing technology are still insufficient in solving practical problems such as lossless demoulding, efficient cleaning and long-term stable use of cheese (especially soft / semi-hard cheese) due to limitations in compatible materials (e.g., rigid structures are not suitable for soft cheese), defects in demoulding methods (e.g., push-through by mold pins can easily damage cheese), or insufficient performance of demoulding components (e.g., single silicone sheets have high adhesion and hard sheets lack elasticity). Utility Model Content

[0008] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0010] Preferably, the telescopic drive mechanism includes a hydraulic device, a support rod, a telescopic rod and a base, the hydraulic device is connected to the top of the base plate, the support rod is connected to the middle of the top of the hydraulic device, the telescopic rod is connected to the middle of the top of the support rod, the base is connected to the top of the telescopic rod, and the composite elastic demolding sheet is installed on the top of the base.

[0011] Preferably, the demolding component also includes a guide component, which includes a guide rod, a limit plate, a vertical plate and a guide ring. The guide rod is connected to the bottom of the workbench, the limit plate is connected to the bottom of the guide rod, the vertical plate is located on the lower surface of the composite elastic demolding sheet, and the guide ring is connected to one side of the bottom of the vertical plate and is movably connected to the outer surface of the guide rod.

[0012] Preferably, the guide component further includes a limit frame and a limit plate, the limit frame is connected to the lower part of the inner surface of the inner frame, the limit plate is connected to the bottom of the composite elastic demoulding sheet, and the vertical plate is connected to the bottom of the limit plate.

[0013] Preferably, a fixing component is further included, which includes an inner groove and an insert block. The inner groove is opened inside the base, and the insert block is connected to the bottom of the limiting plate and inserted into the inner groove.

[0014] Preferably, the fixing component further includes a spring, a cross bar and a pressure plate, the cross bar is connected to both sides of the outer surface of the base, the spring is wound around the outer surface of the cross bar, and the cross bar passes through the middle of the pressure plate.

[0016] Preferably, the thickness of the silicone base layer in the composite elastic release sheet accounts for 70%-80%, the thickness of the food-grade polytetrafluoroethylene surface layer accounts for 20%-30%, and the silicone base layer and the food-grade polytetrafluoroethylene surface layer are connected by a food-grade adhesive layer.

[0017] Preferably, the surface roughness of the food-grade polytetrafluoroethylene surface layer is Ra≤0.5 μm.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model effectively solves the problems of high adhesion of a single silicone sheet and lack of elasticity of a rigid sheet by providing a composite elastic release sheet (composed of a silicone base layer and a food-grade PTFE surface layer). The food-grade PTFE surface layer directly contacts the cheese, eliminating the need for a release agent and improving food safety. At the same time, the silicone base layer compensates for the rigidity of the food-grade PTFE, preventing deformation of the cheese during ejection. The silicone cushioning reduces PTFE wear and extends the life of the mold. The silicone base layer accounts for 70%-80% of the total weight. Its excellent flexibility and elasticity allow it to adapt to the deformation compensation required for cheese ejection, preventing tearing or sticking caused by rigid contact. The food-grade PTFE surface layer accounts for 20%-30% of the total weight, with a surface roughness Ra ≤ 0.5μm and low surface energy. This significantly reduces adhesion between the cheese and the release sheet, resulting in less residue accumulation after long-term use and easier cleaning and maintenance.

[0020] 2. This utility model's telescopic drive mechanism (hydraulic device, support rod, telescopic rod, base) works in conjunction with the composite elastic demolding plate. The hydraulic device drives the telescopic rod up and down, driving the composite elastic demolding plate to apply a uniform push force to the cheese from below. The elastic deformation capacity of the silicone base layer gently lifts the cheese, avoiding deformation or damage caused by localized squeezing or pulling of traditional rigid ejection structures (such as electric push-rod driven bases). This is particularly suitable for soft and semi-hard cheeses with a soft texture and moist surface, effectively improving the integrity of the demolding process.

[0021] 3. The guide components (guide rods, limit plates, guide rings, etc.) of this utility model ensure the stability of the composite elastic release sheet during movement. When the hydraulic device drives the composite elastic release sheet up and down, the guide ring slides synchronously along the guide rod, cooperating with the positioning function of the limit frame and limit plate to prevent the release sheet from shifting or shaking, ensuring uniform thrust and further reducing the risk of damage to the cheese's appearance.

[0022] 4. The fixing components of this utility model (inner groove, insert, spring, positioning rod, etc.) facilitate the removal and maintenance of the composite elastic release sheet. By pulling the pressure plate to disengage the positioning rod from the positioning hole, the insert can be removed from the inner groove and the composite elastic release sheet can be removed separately. During installation, the spring rebounds and pushes the positioning rod into the positioning hole to secure it. This design eliminates the cumbersome maintenance issues of traditional release components and significantly improves the long-term efficiency of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they should not be construed as limiting the present invention.

[0035] Example 1

[0036] See also Figures 1 to 3 The utility model provides a cheese forming mold with a composite silicone demoulding sheet, which includes a supporting component, a demoulding component, a guide component and a fixing component.

[0037] The supporting components include a workbench 100, a forming frame 101, a base plate 102 and a supporting chassis 103, wherein the forming frame 101 is connected to the top of the workbench 100 to define the main space for cheese forming; the supporting chassis 103 is welded to the bottom of the workbench 100 to provide stable support; the base plate 102 is connected between the two supporting chassis 103 to provide an installation base for other components.

[0038] Multiple sets of demolding components can be installed on a single set of equipment. In this embodiment, four sets are provided. The demolding components include forming grooves 204, an inner frame 205, a composite elastic demolding plate 206, and a telescopic drive mechanism. Several forming grooves 204 are defined on the inner surface of the forming frame 101, and the inner frame 205 is located within the inner surface of the forming grooves 204. Together, the two form a molding cavity for accommodating the cheese. Material can be injected into the molding grooves 204, and the inner frame 205 further precisely defines the cheese's shape.

[0039] A composite elastic demolding sheet 206 is provided at the bottom of the molding groove 204. Its shape matches the bottom of the molding cavity. It is specifically composed of a connected silicone base layer and a food-grade polytetrafluoroethylene surface layer. The food-grade polytetrafluoroethylene surface layer is located on the side close to the cheese, and the silicone base layer is located below it. The two are connected by a food-grade adhesive layer; the total thickness of the composite elastic demolding sheet 206 is 2mm, of which the thickness of the silicone base layer accounts for 80%, with a thickness of 1.6mm; the thickness of the food-grade polytetrafluoroethylene surface layer accounts for 20%, with a thickness of 0.4mm, and a surface roughness of Ra=0.4μm, to ensure that its surface is highly smooth and has low surface energy characteristics.

[0040] A limit frame 302 is located below the composite elastic release sheet 206. This limit frame 302 is connected to the lower inner surface of the inner frame 205 and is used to position the composite elastic release sheet 206 to prevent it from creating a gap with the bottom of the molding cavity. The telescopic drive mechanism includes a hydraulic device 200, a support rod 201, a telescopic rod 202, and a base 203. The hydraulic device 200 is connected to the top of the base plate 102, the support rod 201 is connected to the top-center portion of the hydraulic device 200, the telescopic rod 202 is connected to the top-center portion of the support rod 201, and the base 203 is connected to the top of the telescopic rod 202. The composite elastic release sheet 206 is mounted on the top of the base 203. The hydraulic device 200 drives the telescopic rod 202 to move up and down within the support rod 201, driving the composite elastic release sheet 206 within the molding groove 204. The hydraulic device 200 outputs a pressure range of 0.5-2 MPa (adapted to the resistance of cheese demolding), and a lifting speed of 10-20 mm / s.

[0041] The guide components include a guide rod 300, a limit plate 301, a vertical plate 303, a guide ring 305, a limit frame 302, and a limit plate 304. The guide rod 300 is connected to the bottom of the workbench 100, and the limit plate 301 is connected to the bottom of the guide rod 300 to limit the range of movement. The vertical plate 303 is located on the lower surface of the composite elastic release sheet 206. The guide ring 305 is connected to one side of the bottom of the vertical plate 303 and is movably connected to the outer surface of the guide rod 300. When the composite elastic release sheet 206 moves up and down, the guide ring 305 moves synchronously along the guide rod 300 to improve its stability during the movement process. The limit plate 304 is connected to the bottom of the composite elastic release sheet 206, and the vertical plate 303 is also connected to the bottom of the limit plate 304. Together with the limit frame 302, it further ensures the positional accuracy of the composite elastic release sheet 206.

[0042] See also Figure 1 and Figure 5The fixing components include an inner groove 400, an insert 401, a spring 403, a cross bar 404, a pressure plate 405, a positioning rod 402 and a positioning hole 406. The inner groove 400 is opened inside the base 203, and the insert 401 is connected to the bottom of the limit plate 304 and inserted into the inner groove 400 to achieve the initial connection between the base 203 and the limit plate 304; the cross bar 404 is connected to both sides of the outer surface of the base 203, and the spring 403 is wound around the outer surface of the cross bar 404. The preload force of the spring 403 is 5-8N (material: SUS304); the pressure plate 405 passes through the middle of the cross bar 404, and the positioning rod 402 is connected to the pressure plate 4 On one side of 05, positioning holes 406 are provided inside the insert block 401 and the base 203. When the positioning rod 402 corresponds to the positioning hole 406, the spring 403 rebounds to push the positioning rod 402 into the positioning hole 406, completing the fixation of the composite elastic demolding sheet 206 and the base 203; when disassembly and maintenance are required, the pressure plate 405 is pulled outward to disengage the positioning rod 402 from the positioning hole 406, and the composite elastic demolding sheet 206 can be lifted upward for convenient disassembly.

[0043] The working principle of this mold is as follows: During use, cheese liquid is injected into the molding cavity formed by the molding groove 204 and the inner frame 205. After the cheese is formed, the hydraulic device 200 is activated, driving the telescopic rod 202 to move upward within the support rod 201, pushing the composite elastic demolding plate 206 upward through the base 203. The silicone base layer of the composite elastic demolding plate 206 deforms due to its excellent flexibility and elasticity, applying a uniform upward thrust to the cheese from the bottom. At the same time, the food-grade polytetrafluoroethylene on its surface has a surface roughness of Ra ≤ 0.5μm and low surface energy, resulting in extremely low adhesion when in contact with the cheese. This helps the cheese to be smoothly separated from the inner wall of the molding cavity, avoiding deformation or damage to the cheese caused by forced pulling during traditional demolding methods. During this process, the guide ring 305 moves along the guide rod 300 to ensure the smooth movement of the composite elastic demolding plate 206; the limit frame 302 and limit plate 304 restrict its position to prevent deviation. After demolding is complete, the hydraulic device 200 drives the telescopic rod 202 downward, allowing the composite elastic demolding sheet 206 to return to its original shape under its own elastic action. When the composite elastic demolding sheet 206 needs to be maintained or replaced, the positioning rod 402 is disengaged from the positioning hole 406 by pulling the pressure plate 405. The insert 401 can then be withdrawn from the inner groove 400, allowing the composite elastic demolding sheet 206 to be removed independently, making the operation simple and efficient.

[0044] Example 2

[0045] See also Figure 4 The difference between this embodiment and embodiment 1 is that only one group of demoulding components is provided, that is, only one molding groove 204 is provided in the molding frame 101, and the inner frame 205, the composite elastic demoulding sheet 206 and the telescopic driving mechanism are each provided in a corresponding group.

[0046] Specifically, only one molding groove 204 is provided on the inner surface of the molding frame 101, and the inner frame 205 is adapted to the setting of the molding groove 204, and the two constitute a single molding cavity; the shape of the composite elastic demolding sheet 206 matches the bottom of the molding cavity, and the limiting frame 302, limiting plate 304 and guide component below it all correspond to a single group of structural designs; the telescopic drive mechanism only drives the movement of a single group of composite elastic demolding sheets 206.

[0047] This embodiment has a more compact structure and is suitable for small-batch production or customized cheese molding needs (such as high-end handmade cheese and experimental new products), which can reduce equipment costs and simplify the operating process.

[0048] The operating principle of this mold is as follows: It is consistent with Example 1, but because only one set of demolding components is provided, the driving force of the hydraulic device 200 is more concentrated, the movement trajectory of the composite elastic demolding sheet 206 is more uniform, and the guiding function of the guide components is more direct, further improving the stability of the demolding process. Furthermore, the single set of fixed components makes disassembly and maintenance more convenient, making it suitable for scenarios requiring frequent mold changes.

[0049] To further verify the effect of the composite elastic release sheet on reducing cheese adhesion, an adhesion comparison experiment was conducted on Example 1:

[0050] Experimental conditions: Commercially available soft cheese (45% moisture, 28% fat) was selected as the test object. Three sets of release sheets of the same specifications (size: 100mm×100mm×2mm) were prepared:

[0051] Group A (composite sheet of the present invention): silicone base layer (thickness 1.6mm) + food-grade polytetrafluoroethylene surface layer (thickness 0.4mm, Ra=0.4μm);

[0052] Group B (single silicone sheet): pure silicone material (thickness 2mm, Ra=0.8μm);

[0053] Group C (hard metal sheet): 304 stainless steel sheet (thickness 2 mm, Ra = 0.6 μm).

[0054] Experimental method: The cheese liquid was evenly injected into three sets of molds (the mold cavity size matched the release sheet) and left to cure at 25°C for 2 hours. A digital tensile testing machine (accuracy 0.01N) was used to vertically pull the cheese and the release sheet apart, and the maximum adhesion value was recorded (10 tests per group, and the average value was taken).

[0055] Experimental results:

[0056] The average adhesion force of group A (composite sheet) was 1.2N;

[0057] The average adhesion force of group B (single silicone sheet) was 3.8N;

[0058] The average adhesion force of group C (hard metal sheet) was 5.1N.

[0059] Experimental data show that the composite elastic release sheet of the present invention has a low surface energy characteristic of food-grade polytetrafluoroethylene surface (surface energy of about 18 mN / m, significantly lower than about 35 mN / m of silicone and about 72 mN / m of stainless steel) and a smooth surface of Ra≤0.5 μm. Its adhesion to cheese is 68.4% lower than that of a single silicone sheet and 76.5% lower than that of a hard metal sheet, which significantly reduces the adhesion and accumulation of cheese residues and effectively reduces the difficulty of cleaning and maintenance.

[0060] In summary, the molding groove in the present invention is provided on the inner surface of the molding frame, and the inner frame further accurately defines the cheese molding space. On this basis, the silicone elastic demoulding sheet arranged at the bottom has a shape that perfectly matches the bottom of the molding cavity and can fully fit with the bottom of the cheese. When demoulding is required, the telescopic drive mechanism drives the elastic demoulding sheet to move in the molding groove, and utilizes the good flexibility and elasticity of the silicone material to apply a uniform pushing force to the cheese from the bottom, so that the cheese can be easily removed from the molding frame without the need for complex and easily damaging operations like traditional demoulding methods. Traditional demoulding methods often require the use of external force to forcibly separate the cheese from the molding frame, which can easily cause deformation, breakage, etc. of the cheese, affecting the appearance and quality of the product. In this solution, the elastic demoulding sheet, under the action of the telescopic drive mechanism, gently and evenly lifts the cheese, avoiding local squeezing or pulling of the cheese by external force, and can maintain the complete shape and delicate details of the cheese to the greatest extent, effectively improving the product qualification rate and market competitiveness.

[0061] Furthermore, the silicone material's exceptional flexibility and elasticity allow it to perfectly conform to the complex shape of the cheese molding cavity's bottom, maintaining close contact without excessive compression. During demolding, a telescopic drive mechanism activates the elastic release sheet, allowing the silicone, with its excellent elastic deformation, to evenly eject the cheese from the molding frame. Compared to traditional rigid release components, silicone prevents scratches and damage to the cheese surface caused by localized stress concentration during demolding, effectively preventing damage to the cheese's appearance and ensuring that the cheese retains its intact, aesthetically pleasing shape after demolding. During cheese production, ambient temperature may fluctuate, and cheese itself contains oils, fats, and acids. Silicone release sheets maintain stable physical properties across temperature variations, neither hardening or losing their elasticity due to temperature fluctuations nor softening, affecting demolding performance. Furthermore, the silicone material's smooth surface and low surface energy prevent cheese from adhering to the sheet. After demolding, residual cheese debris and stains can be easily cleaned, significantly simplifying cleaning of the release sheet. This mold effectively improves the integrity and efficiency of cheese demoulding and the long-term economic use of the mold through the flexible design of multiple or single sets of demoulding components, combined with the low adhesion and high elasticity characteristics of the composite elastic demoulding sheet and the synergistic effect of various components. It is suitable for cheese production needs of different scales.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
