Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In the following embodiments, a silicone water cup is used as an example.

[0034] like Figures 1 to 4 As shown, this embodiment of the utility model provides a double-layer silicone container mold, comprising:

[0035] The lower mold part 1 has a lower mold cavity 11 provided thereon;

[0036] The middle mold part 2 can be embedded in the lower mold cavity 11, and a middle mold cavity 21 is also provided thereon. An outer silicone wall panel molding cavity A is formed between the outer wall of the middle mold part 2 and the inner wall of the lower mold cavity 11.

[0037] The upper mold part 3 includes an upper mold cover plate 31 and an upper mold body 32. The upper mold body 32 can be embedded in the middle mold cavity 21. The outer wall of the upper mold body 32 and the inner wall of the middle mold cavity 21 form an inner silicone wall panel molding cavity B. A silicone top plate molding cavity C is provided at the connection position between the upper mold cover plate 31 and the upper mold body 32. The silicone top plate molding cavity C communicates with the outer silicone wall panel molding cavity A and the inner silicone wall panel molding cavity B.

[0038] In this embodiment, when molding is required, the middle mold part 2 is embedded into the lower mold cavity 11, and then the upper mold body 32 of the upper mold part 3 is embedded into the middle mold cavity 21. At this time, the upper mold cover plate 31 is stacked on top of the lower mold part 1. The outer silicone wall panel molding cavity A, the inner silicone wall panel molding cavity B, and the silicone top plate molding cavity C are connected. When the silicone is injection molded, a double-layer silicone container is formed. It should be noted that after molding into a silicone container, the bottom of the silicone container is a hollow structure, which requires additional steps to seal. This is not a protected point of this utility model and will not be elaborated here.

[0039] In some embodiments, the bottom wall of the middle mold cavity 21 and the bottom of the upper mold body 32 form an inner silicone tray molding cavity (not shown). Specifically, the inner silicone tray molding cavity enables the container to have a double-layer structure on the sides when it is molded into a double-layer silicone container, while the bottom of the container is currently only sealed on the inner side. When the other layer on the outer side of the bottom is connected, the bottom of the container also has a double-layer structure.

[0040] In some embodiments, such as Figures 1 to 3 As shown, it also includes a demolding part 4, which is located below the lower mold part 1. The demolding part 4 is provided with a demolding groove 41, and a demolding template 5 is provided on the demolding groove 41. The bottom of the lower mold cavity 11 is connected to a demolding cavity, and the bottom of the middle mold part 2 is provided with a demolding rod 6, which can pass through the demolding cavity. Preferably, the lower mold cavity 11 is a hollow structure with openings at both the top and bottom, and the opening at the bottom of the lower mold cavity 11 is smaller than the opening at the top. Preferably, the demolding rod 6 and the middle mold part 2 form a step 7, and the demolding rod 6 is adapted to the demolding cavity. Specifically, when the double-layer container is being formed, the demolding rod 6 is located inside the demolding groove 41 and above the demolding template 5. When the demolding template 5 moves upward, it will push the demolding rod 6 upward, thereby causing the middle mold part 2 and the upper mold part 3 to move upward, thus completing the demolding.

[0041] In some embodiments, such as Figure 5 and 6 As shown, to provide a handle for the double-layer silicone container, a handle groove 12 is provided on the lower mold portion 1, and a handle mold assembly 8 is disposed within the handle groove 12. Specifically, the handle groove 12 includes an upper handle groove 122 and a lower handle groove 121, and a first handle cavity 1211 is also provided on the lower handle groove 121. The handle mold assembly 8 includes a lower handle mold 81 and an upper sealing block 82. The lower handle mold 81 can be embedded in the lower handle groove 121, and a second handle cavity 811 is formed on the lower handle mold 81. The first handle cavity 1211 and the second handle cavity 811 form a silicone handle molding cavity D, which communicates with the outer silicone wall panel molding cavity A. The upper sealing block 82 can be embedded in the upper handle groove 122. A tail block 821 is provided on the side of the upper sealing block 82 away from the lower mold cavity 11. Specifically, during molding, the lower handle mold 81 is embedded into the lower handle groove 12112, and then the upper sealing block 82 seals the upper handle groove 122. The first handle cavity 1211 and the second handle cavity 811 form the silicone handle molding cavity D, so that the silicone container has a handle when molding. Demolding can be easily achieved through the tail block 821.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
