Description

Technical Field

[0001] This utility model relates to the technical field of ice-making appliances, and more specifically to an ice-making mold. Background Technology

[0002] Existing ice-making molds include an upper mold and a lower mold, each with a semi-cavity. When the upper and lower molds are closed, they form a complete inner cavity. The lower mold has side walls around the upper part of the semi-cavity for water storage, while the upper mold has small drainage holes at the top of the semi-cavity. In use, water is poured into the lower mold until the water level is above the semi-cavity. Then, the upper mold is closed and pressed down firmly to squeeze out excess water from the drainage holes. The ice-making mold is then placed in a refrigerator. With this type of ice-making mold, the amount of water injected is difficult to control. Insufficient water may result in incomplete ice cubes; if the mold is overfilled, the water may expand upon freezing, pushing the upper mold out and resulting in irregularly shaped ice cubes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an ice-making mold that can make the ice blocks into regular shapes and easy to demold.

[0004] The technical solution of this utility model is to provide an ice-making mold, including a lower mold, an upper mold, and a mold cover; the lower mold is provided with a lower bottom surface, which forms a lower inner cavity; the upper mold is provided with an upper inner sidewall, which can be connected to the lower bottom surface to form an upper inner cavity, which is a water injection cavity; the mold cover is provided with an upper bottom surface, which can be connected to the upper inner sidewall, and the lower bottom surface, the upper inner sidewall, and the upper bottom surface form a complete ice-making cavity; the volume of the water injection cavity accounts for 0.917% of the volume of the ice-making cavity.

[0005] Compared with the prior art, the ice-making mold of this utility model has the following advantages: Since the density ratio of water to ice is 1:0.917, and water expands in volume after freezing, the volume ratio of the same mass of water to ice is 0.917:1. When using the ice-making mold of this utility model, the upper mold is first connected to the lower mold to obtain the water injection cavity. After the water injection cavity is filled with water, the mold cover is then connected to the upper mold to obtain the ice-making cavity. After all the water in the water injection cavity has frozen, the ice will expand and fill the entire ice-making cavity, forming a regular shape. Then the upper mold and the lower mold are separated at the half cavity position, so that the ice can be easily demolded and removed.

[0006] Preferably, the lower mold has a hemispherical bottom surface forming a hemispherical cavity; the upper inner wall of the upper mold is a curved inner wall, which can be joined to the hemispherical bottom surface to form a cavity larger than a hemisphere, which is a water injection cavity; the upper bottom surface of the mold cover is a spherical top surface, which can be joined to the curved inner wall, and the hemispherical bottom surface, the curved inner wall, and the spherical top surface form a complete spherical cavity; the complete spherical cavity is an ice-making cavity, and the volume of the water injection cavity accounts for 0.917% of the volume of the ice-making cavity. This structure allows the produced ice cubes to be regular spherical and easy to demold. Making the ice cubes spherical slows down the melting rate and prevents the beverage from being diluted too quickly, thus reducing its taste.

[0007] Preferably, the lower mold has an upper connecting wall that surrounds the outer side of the top of the hemispherical bottom surface; the upper mold also has an outer connecting wall that surrounds the outer side of the inner sidewall of the curved surface; the upper connecting wall can be fitted over the outer connecting wall with an interference fit, allowing the inner sidewall of the curved surface to contact the hemispherical bottom surface. With this structure, simply inserting the outer connecting wall into the upper connecting wall and pressing it tightly ensures an interference fit, preventing leakage at the connection point, thus facilitating the connection of the upper mold onto the lower mold.

[0008] Preferably, a lower mold mating surface is provided on the annular end face at the top of the hemispherical bottom surface, and an upper connecting wall surrounds and stands on the outside of the lower mold mating surface; a lower mating surface is provided on the annular end face at the bottom of the curved inner sidewall; when the curved inner sidewall mates with the hemispherical bottom surface, the lower mating surface contacts the lower mold mating surface. This structure allows for smooth mating between the upper and lower molds, resulting in a smooth surface for the ice puck at the mating position.

[0009] Preferably, the outer connecting wall surrounds the lower mating surface, and the curved inner sidewall is sandwiched inside the outer connecting wall, with the connection between the outer connecting wall and the curved inner sidewall being elastic. With this structure, the connection between the outer connecting wall and the curved inner sidewall is elastic. On one hand, when the outer connecting wall connects to the upper connecting wall, it easily deforms elastically inward, facilitating an interference fit with the upper connecting wall and making it convenient to mate the upper mold with the lower mold. On the other hand, by pinching the opposite sides of the outer connecting wall, it can further deform elastically inward, easily separating from the upper connecting wall and facilitating the removal of the upper mold from the lower mold.

[0010] Preferably, the top of the outer connecting wall is provided with an annular mold opening end face. The outer ring diameter of the mold opening end face is larger than the outer ring diameter of the top of the upper connecting wall. When the inner sidewall of the curved surface is in contact with the hemispherical bottom surface, the outer edge of the mold opening end face is located outside the top of the upper connecting wall. With this structure, when demolding, the outer edge of the mold opening end face can be grasped and the outer connecting wall can be pulled outward to separate the outer connecting wall from the upper connecting wall, making it easier to remove the upper mold from the lower mold.

[0011] Preferably, the upper mold has an inner connecting wall that surrounds the outer side of the top of the inner sidewall of the curved surface. The inner connecting wall has at least one overflow notch to allow water located between the inner sidewall of the curved surface and the inner connecting wall to drain outwards. The mold cover has an outer mold cover wall that surrounds the outer side of the bottom surface of the spherical cap. The inner connecting wall can be fitted onto the outer mold cover wall with an interference fit, allowing the bottom surface of the spherical cap to align with the inner sidewall of the curved surface. With this structure, simply inserting the outer mold cover wall into the inner connecting wall and pressing it tightly ensures an interference fit, preventing water leakage at the connection point. This allows the mold cover to be easily attached to the upper mold.

[0012] Preferably, an upper mold mating surface is provided on the annular end face at the top of the inner sidewall of the curved surface, and an inner connecting wall surrounds the outer side of the upper mold mating surface; a mold cover mating surface is provided on the annular end face at the bottom of the upper surface of the puck; when the upper surface of the puck mates with the inner sidewall of the curved surface, the mold cover mating surface contacts the upper mold mating surface. This structure allows for a smooth mating between the mold cover and the upper mold, resulting in a smooth surface for the puck at the mating point.

[0013] Preferably, an upper mold insertion groove is provided between the inner connecting wall and the upper mold mating surface; a mold cover insertion protrusion is provided at the lower end of the outer wall of the mold cover, and the mold cover insertion protrusion surrounds and stands on the outer side of the mold cover mating surface; when the upper bottom surface of the spherical crown mates with the curved inner wall, the mold cover insertion protrusion is inserted into the upper mold insertion groove. This structure facilitates the extrusion of water located between the curved inner wall and the inner connecting wall, preventing water located between the curved inner wall and the inner connecting wall from entering the ice-making cavity.

[0014] Preferably, a vent is provided at the top of the bottom surface of the spherical cap. This structure ensures that the air pressure inside the ice-making chamber is always consistent with the outside air pressure, facilitating demolding.

[0015] Preferably, the lower mold is provided with a lower support wall, which surrounds the outer side of the hemispherical bottom surface to support the lower mold. With this structure, the spherical ice-making mold of this invention can be used independently without the need for an external support. Attached Figure Description

[0023] Example 1:

[0024] like Figures 1 to 3 As shown, the ice-making mold of this utility model includes a lower mold 1, an upper mold 2, and a mold cover 3. The lower mold is provided with a hemispherical bottom surface 1-1, which forms a hemispherical inner cavity 1-2. A lower support wall 1-3 and an upper connecting wall 1-4 are provided on the outer side of the hemispherical bottom surface 1-1. The lower support wall 1-3 is located below the upper connecting wall 1-4 and surrounds the outer side of the hemispherical bottom surface 1-1 to support the lower mold. A lower mold mating surface 1-5 is provided on the annular end face at the top of the hemispherical bottom surface 1-1, and the upper connecting wall 1-4 surrounds the outer side of the lower mold mating surface 1-5 to connect with the upper mold 2.

[0025] The upper mold 2 is provided with a curved inner sidewall 2-1, an outer connecting wall 2-2, and an inner connecting wall 2-4. The curved inner sidewall 2-1 can be mated to the hemispherical bottom surface 1-1 to form an inner cavity larger than a hemisphere, which is a water injection cavity. A lower mating surface 2-3 is provided on the annular end face at the bottom of the curved inner sidewall 2-1, and the outer connecting wall 2-2 stands around the lower mating surface 2-3, with the curved inner sidewall 2-1 sandwiched inside the outer connecting wall 2-2.

[0026] The upper connecting wall 1-4 is fitted over the outer connecting wall 2-2 with an interference fit, allowing the curved inner sidewall 2-1 to mate with the hemispherical bottom surface 1-1, and the lower mating surface 2-3 to contact the lower mold mating surface 1-5. The top of the outer connecting wall 2-2 has an annular mold opening end face 2-8. The outer diameter of the mold opening end face 2-8 is larger than the outer diameter of the top of the upper connecting wall 1-4. When the curved inner sidewall 2-1 mates with the hemispherical bottom surface 1-1, the mold opening end face 2-8 is positioned above the upper connecting wall 1-4, with its outer edge located outside the top of the upper connecting wall 1-4. To demold, the outer edge of the mold opening end face 2-8 can be grasped and pulled outwards to separate the outer connecting wall 2-2 from the upper connecting wall 1-4, facilitating the removal of the upper mold 2 from the lower mold 1.

[0027] An upper mold mating surface 2-7 is provided on the annular end face at the top of the inner curved sidewall 2-1. An inner connecting wall 2-4 surrounds the outer side of the upper mold mating surface 2-7 and is used to mate with the mold cover 3. An upper mold insertion groove 2-6 is provided between the inner connecting wall 2-4 and the upper mold mating surface 2-7.

[0028] The mold cover 3 is provided with a spherical top bottom surface 3-1 and an outer side wall 3-2. The spherical top bottom surface 3-1 can be connected to the upper hemispherical bottom surface 1-1 of the curved inner side wall 2-1, the curved inner side wall 2-1 and the spherical top bottom surface 3-1 to form a complete spherical inner cavity. The complete spherical inner cavity is an ice-making cavity, and the volume of the water injection cavity accounts for 0.917% of the volume of the ice-making cavity.

[0029] The outer wall 3-2 of the mold cover surrounds the outer side of the upper bottom surface 3-1 of the spherical crown. A mold cover mating surface 3-3 is provided on the annular end face of the bottom of the upper bottom surface 3-1 of the spherical crown. A mold cover insertion protrusion 3-4 is provided at the lower end of the outer wall 3-2 of the mold cover, surrounding the outer side of the mold cover mating surface 3-3. The inner connecting wall 2-4 can be fitted onto the outer wall 3-2 of the mold cover and has an interference fit with it, allowing the upper bottom surface 3-1 of the spherical crown to mate with the curved inner wall 2-1. The mold cover insertion protrusion 3-4 is inserted into the upper mold insertion groove 2-6, and the mold cover mating surface 3-3 contacts the upper mold mating surface 2-7.

[0030] At least one overflow notch 2-5 is provided on the inner connecting wall 2-4. When the mold cover insertion protrusion 3-4 is pressed into the upper mold insertion groove 2-6, water located between the inner curved side wall 2-1 and the inner connecting wall 2-4 can be discharged to the outside through the overflow notch 2-5, preventing excess water from entering the ice-making cavity. A vent hole 3-5 is also provided on the top of the bottom surface 3-1 of the spherical cap. The vent hole 3-5 ensures that the air pressure in the ice-making cavity is always consistent with the outside air, facilitating demolding.

[0031] In use, the ice mold of this invention is first joined to the lower mold 1 to form the water injection cavity. After filling the water injection cavity with water, the mold cover 3 is then joined to the upper mold 2 to form the ice-making cavity. Since the density ratio of water to ice is 1:0.917, and water expands in volume after freezing, the volume ratio of the same mass of water to ice is 0.917:1. In the ice mold of this invention, the volume of the water injection cavity accounts for 0.917 of the volume of the ice-making cavity. Therefore, after all the water in the water injection cavity has frozen, the ice will expand and fill the entire ice-making cavity, forming a regular sphere. Then, the upper mold 2 is separated from the lower mold 1 at the hemisphere position, that is, the position with the largest diameter of the spherical ice block. In this way, the ice block can be easily demolded and removed.

[0032] The upper mold can be made by one-piece injection molding. In this way, the connection between the outer connecting wall and the inner connecting wall 2-4 and the inner side wall of the curved surface is elastic, which makes it easy to connect the upper mold 2 to the lower mold 1, and also makes it easy to connect the mold cover 3 to the upper mold 2. It also makes it easy to demold, so that the upper mold 2 can be separated from the lower mold 1 to remove the spherical ice block.

[0033] In other embodiments, the ice mold of this invention can also be made into other shapes such as cubes or ellipsoids.

[0034] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
