Description

Technical Field

[0001] This application relates to the field of ice cream production technology, specifically to a mold. Background Technology

[0002] In the field of ice cream flavoring production, with the continuous growth of consumers' demand for diversified appearance and taste of ice cream products, the innovation and optimization of flavoring production technology has become the key to the industry's development. Flavoring production aims to give ice cream a unique shape and rich internal structure. This process involves a series of complex steps, from mixing raw materials, freezing, filling to final molding and demolding, each of which has a significant impact on product quality and production efficiency.

[0003] Currently, in the demolding process of ice cream flavoring production, the industry generally uses hot water spraying on metal molds. Specifically, after the ice cream freezes and solidifies in the mold, hot water is sprayed onto the mold surface. The large heat exchange between the hot water and the low-temperature mold reduces the adhesion between the inner wall of the metal mold and the ice cream, allowing the ice cream to be easily removed from the mold, thus completing the demolding process.

[0004] However, this existing technology, which relies on hot water for demolding, has many drawbacks. On the one hand, hot water demolding requires a large amount of hot water, which not only wastes water resources but also negatively impacts the achievement of energy conservation and emission reduction goals. On the other hand, the process of heating water consumes a large amount of energy, significantly increasing production costs and energy consumption, whether electric heating or other traditional energy heating methods are used. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a mold including a first housing and a second housing. The first housing is disposed outside the second housing, and the first housing and the second housing are nested together by an interference fit. The second housing is formed of Teflon.

[0006] According to one embodiment provided in this application, both the first shell and the second shell are columnar.

[0007] According to one embodiment of this application, it further includes a template strip with multiple arc-shaped holes symmetrically arranged at both ends. The template strip includes multiple first holes for placing the first housing.

[0008] According to one embodiment of this application, the first hole is evenly distributed along the length of the template strip, and the first hole is disposed between the arc-shaped holes.

[0009] According to one embodiment of this application, both the first housing and the second housing have arc-shaped caps at their ends, and the caps are located at the end of the first housing away from the first hole.

[0010] According to one embodiment of this application, a baffle is also included, which is disposed on the side of the template near the top and partially blocks the first housing.

[0011] According to one embodiment of this application, both the second housing and the first housing have through holes at their ends away from the top, and the second housing is disposed in the through hole of the first housing.

[0012] According to one embodiment provided in this application, the inner diameter of the first housing is R, which satisfies R > 2.2 mm.

[0013] According to one embodiment provided in this application, the thickness of the second shell is D, which satisfies 0.6mm > D > 0.45mm.

[0014] According to one embodiment of this application, the first housing is formed by processing a metal alloy.

[0015] Compared with the prior art, the significant technological advancement of this application lies in the fact that the second shell is formed by processing Teflon. Teflon has the characteristic of a smooth surface, which can effectively reduce the adhesion between the product and the inner wall of the mold after the product such as ice cream is formed. It can be easily demolded without the need for hot water to melt, which improves the demolding efficiency and reduces the occurrence of damage, deformation or residue of the product due to excessive adhesion during the demolding process, thus ensuring the integrity and quality of the product.

[0027] In the field of ice cream flavoring production, with the continuous growth of consumers' demand for diversified appearance and taste of ice cream products, the innovation and optimization of flavoring production technology has become the key to the industry's development. Flavoring production aims to give ice cream a unique shape and rich internal structure. This process involves a series of complex steps, from mixing raw materials, freezing, filling to final molding and demolding, each of which has a significant impact on product quality and production efficiency.

[0028] Currently, in the demolding process of ice cream flavoring production, the industry generally uses hot water spraying on metal molds. Specifically, after the ice cream freezes and solidifies in the mold, hot water is sprayed onto the mold surface. The large heat exchange between the hot water and the low-temperature mold reduces the adhesion between the inner wall of the metal mold and the ice cream, allowing the ice cream to be easily removed from the mold, thus completing the demolding process.

[0029] However, this existing technology, which relies on hot water for demolding, has many drawbacks. On the one hand, hot water demolding requires a large amount of hot water, which not only wastes water resources but also negatively impacts the achievement of energy conservation and emission reduction goals. On the other hand, the process of heating water consumes a large amount of energy, significantly increasing production costs and energy consumption, whether electric heating or other traditional energy heating methods are used.

[0030] Appendix Figure 1 This is a schematic diagram of the structure of a mold provided in an embodiment of this application, with attached... Figure 2 for Figure 1 Top view of the structure.

[0031] like Figure 1 , Figure 2 As shown, a mold includes a first housing 100 and a second housing 200. The first housing 100 is disposed outside the second housing 200. The first housing 100 and the second housing 200 are nested together by an interference fit. The second housing 200 is formed by processing Teflon.

[0032] It should be noted that traditional molding production methods rely on hot water for demolding, consuming a large amount of water resources and requiring significant energy for heating. This mold, however, through a special design, eliminates the hot water demolding step, directly reducing the amount of hot water used and lowering the energy consumption required for heating.

[0033] The second shell 200 is formed by processing Teflon. Teflon has the characteristic of a smooth surface, which can effectively reduce the adhesion between the product and the inner wall of the mold after the product such as ice cream is formed. It can be easily demolded without the need for hot water to melt, which improves demolding efficiency and reduces the occurrence of damage, deformation or residue of the product due to excessive adhesion during the demolding process, thus ensuring the integrity and quality of the product.

[0034] It should also be noted that once the ice cream is frozen and set in the mold, the adhesion between the ice cream and the inner wall of the mold is extremely small due to the non-stick properties of Teflon. Compared with traditional metal molds, ordinary metal surfaces are relatively rough and have a certain degree of adhesion, making it easy for ice cream to stick to them. Demolding requires a large amount of external force, while hot water demolding utilizes the principle of thermal expansion and contraction and reduced adhesion to assist in demolding.

[0035] When using molds made of Teflon, even if the ice cream contains a large amount of extruded ingredients and has strong adhesion, the low surface energy of Teflon allows for easy demolding. Furthermore, the smooth surface of Teflon reduces friction during demolding, further simplifying the process, ensuring the integrity of the ice cream, minimizing material waste, and improving product quality and production efficiency.

[0036] The first housing 100 is disposed outside the second housing 200, and the two are nested together by an interference fit. This installation method makes the overall structure of the mold tight and stable. During the production process, it can effectively avoid problems such as mold loosening or displacement affecting the pouring and molding accuracy of the product, ensuring the stability and reliability of the mold during long-term use, extending the service life of the mold, and reducing production costs.

[0037] According to one embodiment provided in this application, both the first housing 100 and the second housing 200 are columnar.

[0038] It should be noted that in the mold provided in this embodiment, the shapes of the first shell 100 and the second shell 200 are both adapted to the shape required for the production of ice cream by the patterned line. The ice cream produced by the patterned line in this application is mostly rod-shaped, so a cylindrical mold shell is used.

[0039] According to one embodiment of this application, it further includes a template 300, with multiple arc-shaped holes symmetrically arranged at both ends of the template 300. The template 300 includes multiple first holes, which are used to place the first housing 100.

[0040] It should be noted that the mold strip 300 features multiple symmetrically arranged arc-shaped holes at both ends, a design that facilitates mold installation. In actual production, these arc-shaped holes can mate with relevant fixing components on the production line, allowing for quick and precise installation of the mold above the pattern line, improving installation efficiency and positioning accuracy. This symmetrical design ensures the stability of the mold after installation, preventing installation deviations from affecting the pouring and molding quality of the product.

[0041] The mold strip 300 is provided with multiple first holes for housing the first housing 100, providing a stable support structure for the first housing 100. The design of multiple first holes allows for flexible adjustment of the number and position of the first housing 100 according to different production needs, enhancing the mold's adaptability to different production scales and product specifications. Simultaneously, the tight fit between the first holes and the first housing 100 further stabilizes the overall structure of the mold, ensuring that no displacement or shaking occurs during production, thus guaranteeing product consistency and stability.

[0042] According to one embodiment of this application, the first hole is evenly distributed along the length of the template 300, and the first hole is disposed between the arc-shaped holes.

[0043] According to one embodiment provided in this application, both the first housing 100 and the second housing 200 have arc-shaped caps at their ends, and the caps are located at the end of the first housing 100 away from the first hole.

[0044] It should be noted that the first holes are evenly distributed along the length of the mold strip 300 and positioned between the arc-shaped holes. This layout ensures a more uniform and balanced installation of the first housing 100 on the mold strip 300. The evenly distributed first holes ensure uniform support force on the first housing 100, preventing the mold from tilting or shaking due to uneven force during production, thus guaranteeing the accuracy of product pouring and molding. Simultaneously, the first holes, located between the arc-shaped holes, complement each other in position, further optimizing the stability of the mold connection to the production line, reducing the risk of mold displacement during operation, and improving the reliability of the entire production process.

[0045] It should also be noted that both the first housing 100 and the second housing 200 have arc-shaped caps at their ends, with the caps located at the end of the first housing 100 furthest from the first hole. This design has a positive impact on product molding and demolding. The arc-shaped caps help the product to be molded better within the mold, avoiding sharp edges or irregular shapes at the ends, thus improving the product's appearance quality. During demolding, the arc-shaped design reduces the contact area between the product and the mold ends, lowering demolding resistance and making it easier for the product to exit the mold, further improving demolding efficiency and reducing the possibility of product damage during demolding. In addition, the arc-shaped caps prevent raw materials from accumulating at the mold ends during production, ensuring mold cleanliness and facilitating the continuous and stable production of high-quality products.

[0046] According to one embodiment of this application, a baffle 310 is also provided. The baffle 310 is disposed on the side of the template 300 near the top and partially blocks the first housing 100.

[0047] It should be noted that the baffle 310 is located on the side of the mold strip 300 near the top and partially covers the first housing 100. During the production process of the ice cream coloring line, the baffle 310 can cooperate with the transmission device to quickly move on the coloring line production line and improve production efficiency.

[0048] In addition, the baffle 310 protects part of the mold structure. During the production process, the mold may be affected by external factors. The baffle 310 can block some foreign objects that may impact the mold, reduce the risk of damage to the first housing 100 due to external collisions, and extend the service life of the mold.

[0049] According to one embodiment of this application, both the second housing 200 and the first housing 100 have through holes at their ends away from the top, and the second housing 200 is disposed in the through hole of the first housing 100.

[0050] According to one embodiment provided in this application, the inner diameter of the first housing 100 is R, which satisfies R > 2.2 mm.

[0051] It should be noted that both the second shell 200 and the first shell 100 have through holes at their ends furthest from the top, and the second shell 200 is disposed within the through hole of the first shell 100. This structure further strengthens the connection between the two shells of the mold. The through-hole fit further limits the relative axial position of the first shell 100 and the second shell 200, reducing potential relative displacement during production and improving the overall stability of the mold structure. Simultaneously, the tight fit also improves the mold's sealing performance to a certain extent, preventing raw materials from leaking through the gaps between the two shells during product manufacturing, ensuring product quality and a clean production environment, and reducing material waste and equipment contamination caused by leakage.

[0052] The inner diameter of the first housing 100 is R, and R > 2.2mm. This dimensional design brings more possibilities to the application of the mold. The larger inner diameter allows the mold to adapt to the production needs of products with various sizes and specifications. In the production of ice cream flavoring lines, it can be used to mold larger or special-shaped products, expanding the applicability of the mold. Moreover, this inner diameter also facilitates cleaning and maintenance during the production process. Operators can more easily clean and inspect the inside of the mold, ensuring that the mold always maintains a good working condition, improving production efficiency and reducing maintenance costs.

[0053] According to one embodiment provided in this application, the thickness of the second housing 200 is D, which satisfies 0.6mm > D > 0.45mm.

[0054] It should be noted that the thickness of the second shell 200 is limited to the range of 0.6mm > D > 0.45mm, achieving a good balance between demolding performance and mold strength. Teflon material itself has excellent demolding properties; a thinner shell further reduces the adhesion between the product and the mold's inner wall, making the demolding process smoother, reducing resistance during demolding, lowering the risk of surface damage, and ensuring the integrity of the product's appearance and shape. At a shell thickness close to 0.6mm, the mold maintains sufficient strength, making it less prone to deformation or damage under repeated use, product injection pressure, and collisions during production, extending the mold's lifespan, reducing mold replacement frequency, and lowering production costs.

[0055] Within this thickness range, the heat transfer efficiency of the mold is optimized. In the production process of ice cream flavoring lines, the product molding requires a freezing process, and a suitable mold thickness helps to more effectively transfer heat between the mold and the product. The thinner second shell 200 allows heat to be transferred away from the product more quickly, accelerating the freezing and molding process and improving production efficiency. Simultaneously, after demolding, the mold can recover to a suitable temperature for refilling raw materials relatively quickly, reducing waiting time during production and further improving overall production efficiency.

[0056] According to one embodiment of this application, the first housing 100 is formed by processing a metal alloy.

[0057] It should be noted that metal alloys have excellent thermal conductivity, a property that helps accelerate heat exchange between the mold and the external environment during ice cream production. During the product freezing stage, this allows the ice cream inside the mold to cool and solidify more quickly, shortening the production cycle and improving efficiency. After demolding, it also accelerates the cooling of the mold, allowing it to quickly return to a suitable temperature for refilling raw materials, preparing it for the next round of production. Furthermore, the close fit between the inner wall of the first shell 100 and the outer wall of the second shell 200 further optimizes heat transfer between the two shells, ensuring uniform heating and cooling of the product within the mold and contributing to improved product quality consistency.
