[0030] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0031] See Figures 1-10 This is one embodiment of an ice-making mold proposed in this utility model. An ice-making mold 100 includes an upper mold 10 and a lower mold 20, which can be arranged to form an ice-making cavity 30. The upper mold 10 has a liquid injection gap 133, which can deform and open under stress to form an injection port for injecting liquid into the ice-making cavity 30. The opening width of the liquid injection gap 133 is relatively small; under stress, the opening of the liquid injection gap 133 becomes larger, forming an injection port to facilitate liquid injection. Figure 6 As shown. The upper mold 10 is made of a stress-deformable material, which can deform when subjected to force around the injection gap 133.

[0032] In this embodiment, when ice is needed, a certain external force is applied to the injection gap 133 of the upper mold 10 to deform and open the injection gap 133, forming an injection port. Afterward, the injection operation can be performed directly. Once the injection is complete, the external force is removed, and the injection gap 133 returns to its original state, eliminating the need for additional sealing operations. This greatly simplifies the ice-making process and improves efficiency. The injection and sealing functions are achieved through the deformable injection gap 133 of the upper mold 10 itself, fundamentally solving the problem of easily lost sealing plugs and improving the practicality of the ice-making mold. Utilizing the deformation characteristics of the upper mold material to create the injection gap 133 ensures good sealing of the ice-making mold 100, reducing liquid leakage. Furthermore, it avoids wear and damage that may be caused by frequent disassembly and installation of the sealing plug, thereby improving the mold's durability.

[0033] In some embodiments of this application, the ice-making cavity 30 is spherical, and both the upper mold 10 and the lower mold 20 have smooth shapes. The ice-making mold 100 can be used for physical cooling, such as for reducing swelling and applying cold compresses, or for reducing fever. The smooth shapes of the upper mold 10 and the lower mold 20, when used to wrap ice for cold compresses, reduce heat buildup when held. The smooth shapes conform to the curves of the human body, such as the hands and forehead, reducing the loss of cold energy through gaps and improving the cooling effect, while also preventing sharp edges from hurting the skin.

[0034] In some embodiments of this application, an upwardly extending protective cylinder 12 is provided on the upper mold 10. The protective cylinder 12 is located outside the liquid injection gap 133, which is located inside the protective cylinder 12. The protective cylinder 12 facilitates lifting the ice-making mold 100 and allows for easy application of force. Simply pinch the sides of the protective cylinder 12 with your fingers and gently apply force outward or inward to deform and open the liquid injection gap 133, thus providing protection. During liquid injection, the protective cylinder 12 surrounds the deformed injection port of the liquid injection gap 133, forming a ring-like barrier structure. Even if the liquid injection speed is too fast or the liquid flow rate is unstable due to the deformation of the injection port, the protective cylinder 12 can block splashing liquid, preventing it from spilling onto the outside of the mold and reducing cleaning workload. At the same time, during freezing, it prevents liquid from overflowing from the liquid injection gap 133 and flowing into the refrigerator.

[0035] In some embodiments of this application, the lower outer end of the protective cylinder 12 is a compression force-applying part. By manually squeezing and deforming the force-applying part along the length of the injection gap 133, the protective cylinder 12 and the upper mold 10 near the injection gap 133 deform, increasing the width and opening the injection gap 133. The protective cylinder 12 extends in an arc shape in the upward direction. When the force-applying part is squeezed, the arc-shaped structure can convert the lateral extrusion force into tensile stress along the arc, causing the upper mold near the injection gap to deform uniformly, avoiding material fatigue or permanent deformation caused by localized stress concentration.

[0036] In some embodiments of this application, the upper mold 10 has a lower upper mold 15, an upper mold top 16 located inside the protective cylinder 12, and a protective cylinder 12 connected to the upper end of the lower upper mold 15. The injection gap 133 is opened in the upper mold top 16, and the wall thickness of the upper mold top 16 is smaller than that of the upper mold bottom 15, which facilitates deformation under stress. The upper mold top 16 serves as the load-bearing area of ​​the injection gap 11. Its thinner wall thickness significantly reduces the external force threshold required for deformation, allowing the injection gap to open with only slight force. Moreover, the gap width changes linearly with the magnitude of the applied force, and the user can flexibly control the opening size according to the injection speed. The thick-walled design of the lower upper mold 15 provides a stable support base for the protective cylinder 12, preventing the entire upper mold 10 from shifting unexpectedly when pressure is applied, and ensuring that the deformation is precisely concentrated in the injection gap 133 area.

[0037] In some embodiments of this application, the wall thickness of the protective cylinder 12 is located between the wall thickness of the upper mold top 16 and the wall thickness of the upper mold bottom 15. When the user applies pressure to the extrusion force application part, the thick wall rigidity of the upper mold bottom 15 ensures that the external force is not dispersed, while the medium-thick wall of the protective cylinder 12 bears the rigid transmission, while retaining appropriate elasticity to avoid force transmission discontinuity due to excessive rigidity or force loss due to excessive flexibility; it can smoothly transmit the concentrated force of the upper mold bottom 15 to the thin-walled area of ​​the upper mold top 16, making the deformation of the injection gap 11 more uniform and controllable.

[0038] In some embodiments of this application, the upper mold 10 is provided with a drain nozzle 13, and a sealing membrane 132 is provided inside the drain nozzle 13. The thickness of the sealing membrane 132 is less than the wall thickness of the upper mold top 16, and the smaller thickness of the sealing membrane 132 facilitates deformation. A liquid injection slit 133 is formed on the sealing membrane 132. The drain nozzle 13 has two opposing lips 131 and a sealing membrane 132 located between the two lips 131. The drain nozzle 13 can accurately guide the liquid flow to the injection port formed after the injection slit 133 is deformed; reducing the amount of liquid falling outside the drain nozzle 13. The two opposing lips 131 form a channel-type guide structure, further constraining the liquid flow path and preventing liquid deviation due to flow rate fluctuations during injection.

[0039] In some embodiments of this application, the drainage nozzle 13 has two upwardly protruding lips 131. The thickness of the lips 131 increases from both ends towards the middle, forming a thickened support area in the middle. The lips 131 serve both support and drainage functions. When the user pinches the squeezing part to apply force and open the injection gap 133, the thickened area in the middle can disperse stress, preventing the lips 131 from bending, breaking, or permanently deforming due to excessive local stress. At the same time, during the alternating freezing and thawing process of the mold, the thickened structure in the middle can reduce warping caused by uneven material shrinkage, ensuring that the lips 131 maintain a regular shape for a long time and providing stable support for the sealing film 132.

[0040] In some embodiments of this application, the lip 131 protrudes in height from both ends toward the middle, and the lip 131 is an arc extending along the length of the injection gap 133. The lip 131 extends in an arc along the length of the injection gap 133, and in conjunction with the height gradient of low ends and high middle, the inner side of the lip 131 forms a ring surrounding the injection gap 133.

[0041] In some embodiments of this application, the drainage nozzle 13 has two opposing lips 131, and a sealing film 132 is connected between the two lips 131; the sealing film 132 extends downward from both ends towards the middle. The width of the sealing film 132 decreases near the ends. When force is applied to open the injection slit 133, the downward extension of the sealing film 132 makes it easier for the sealing film 132 to deform under the pressure of the lips 131. The downward tilting direction of the middle of the sealing film 132 is consistent with the opening direction of the slit caused by the applied force, reducing deformation resistance. The user can smoothly open and close the injection slit 133 without applying much force. At the same time, the tilted structure of the sealing film 132 improves the ease of operation of the injection port formed after the injection slit 133 is opened.

[0042] In some embodiments of this application, the injection slit 133 has a slit body 1331 and a bifurcated portion at the end of the slit body 1331. The bifurcated portion has two bifurcated slits 1332 that are spaced apart from each other in a direction away from the slit body 1331. The bifurcated slits 1332 are connected to the end of the slit body 1331. When a user pinches the lip 131 and applies force, the deformation of the injection slit is mainly concentrated in the slit body 1331. The two bifurcated slits 1332 of the bifurcated portion can disperse the local stress to the end, avoiding stress concentration that could cause the slit body 1331 to tear. At the same time, the presence of the bifurcated slits 1332 allows for a larger deformation range at the end of the slit, requiring only a smaller external force to open the slit body 1331, further lowering the threshold for applying force. The sealing film 132, with its inclined shape extending downwards from both ends to the middle, positions the main body of the slit 1331 at a lower position in the middle of the film, while the bifurcated portions are located at higher positions at both ends. When force is applied, the bifurcated portions naturally open with the inclined deformation of the sealing film 132, causing the main body of the slit 1331 to open and close synchronously. This avoids local wrinkles or deformation jams caused by mismatch between the slit structure and the film shape, ensuring a smooth and coordinated opening and closing process. When no external force is applied, the bifurcated slit 1332, due to the material elasticity and inclined shape of the sealing film 132, will naturally move towards and close towards the main body of the slit 1332, forming a complete sealing structure together with the main body of the slit 1331.

[0043] In some embodiments of this application, two bifurcated slits 1332 are symmetrically arranged relative to the slit body 1331, with an included angle of 60° to 120° between the bifurcated slits 1332. The symmetrical arrangement of the two bifurcated slits 1332 relative to the slit body 1331 allows stress to be evenly distributed along the axis of symmetry to both ends of the slit. When the user pinches and squeezes the lip, the symmetrical bifurcated slits deform synchronously, preventing the slit body 1331 from shifting to one side due to excessive force on one side. This reduces fatigue damage to the slit material caused by long-term asymmetrical deformation, extends the service life of the injection slit 133, and ensures uniform slit width with each opening and closing, improving the consistency of injection and sealing. The included angle of 60° to 120° allows the bifurcated slits to fully utilize the elasticity of the sealing film during deformation, requiring only a small external force to achieve synchronous opening, and stress is smoothly transmitted along the included angle direction, reducing the risk of breakage at the connection point.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
