Description

Technical Field

[0001] This utility model relates to the technical field of cat bed molding molds, and in particular to a demolding structure for a cat bed molding mold. Background Technology

[0002] Cat beds, as the name suggests, are places where cats sleep, just like beds for humans. Currently, there are many types of cat beds available. Among them, PET material is used because of its good mechanical properties and wide temperature range. Therefore, many cat beds are now made of PET material, and cat beds made by molding are generally popular in the market.

[0003] Existing cat bed molding molds require a period of time to cool and solidify after completion, before the mold is manually removed from the molding cavity. This method is slow, and the solidified PET material may stick to the inner wall of the molding cavity, potentially causing damage during removal. Therefore, a demolding structure for cat bed molding molds is designed to achieve rapid demolding, prevent the mold from sticking to the inner wall of the molding cavity, and accelerate the cooling and solidification of the mold.

[0022] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0023] like Figure 1-4 As shown, a demolding structure for a cat bed molding die includes: a film-forming box 1 and a top plate 2; a film-forming cavity 11 is provided in the center of the inner cavity of the film-forming box 1, and four round holes 111 are provided on the outer wall of the top side of the film-forming cavity 11; a movable bottom plate 112 is provided on the right side of the film-forming cavity 11; a first cylinder 13 is provided in the center of the right side of the inner cavity of the film-forming box 1, and the output shaft of the first cylinder 13 is connected to the movable bottom plate 112; hollow cylinders 17 are provided on the front and back inner walls of the top side of the inner cavity of the film-forming box 1, and two water outlets are provided at the top of the hollow cylinders 17, and a first connecting pipe 14 and a second connecting pipe 15 are respectively connected through the water outlets, and the ends of the two first connecting pipes 14 and the second connecting pipe 15 away from the hollow cylinders 17 are connected through the round holes 111; a pressing film 22 is provided in the center of the side of the top plate 2 near the inner cavity of the film-forming box 1, and the shape and size of the front of the pressing film 22 are adapted to the shape and size of the front of the film-forming cavity 11. It should be noted that the cat bed is wider at the top and narrower at the bottom. Therefore, the movable bottom plate 112 at the bottom can push the bottom of the model upward to push the film-forming model out from the inside, thereby achieving the purpose of automatic and convenient demolding. The shape and size of the top plate 2 in the top view are adapted to the shape and size of the film-forming box 1 in the top view. Furthermore, a connecting block is provided on the inner wall of the film-forming box 1. The connecting block is connected to the outer wall of the film-forming cavity 11 to fix the film-forming cavity 11 inside.

[0024] like Figure 1-4As shown in one embodiment, the top plate 2 has a hollow structure in the center, and a cross-shaped connecting rod 21 is provided in the center. The cross-shaped connecting rod 21 and the pressure film 22 are integrally formed. It should be noted that this design can enhance the connection point between the top plate 2 and the pressure film 22, making their connection more secure.

[0025] like Figure 1-4 As shown in one embodiment, guide posts 12 are provided at each of the four corners of the film-forming box 1 near the top plate 2, and guide post holes matching the guide posts 12 are opened at each of the four corners of the top plate 2 near the film-forming box 1. It should be noted that this design facilitates the operator to connect the top plate 2 and the film-forming box 1 together as required.

[0026] like Figure 1-4 As shown, in one embodiment, a piston is provided at the bottom of the inner cavity of the hollow cylinder 17, and a fixing ring 16 is provided on the body of the hollow cylinder 17. One side of the fixing ring 16 is connected to the inner wall of the film-forming box 1. A water inlet 19 is connected through the center of the hollow cylinder 17, and the side of the water inlet 19 away from the hollow cylinder 17 extends outward through the inner wall of the film-forming box 1 to its outer side. A switch valve is provided on the tube body of the water inlet 19 located on the outer wall of the film-forming box 1. Two second cylinders 18 are provided at both ends of the inner wall of the right side of the film-forming box 1 near the top. The two second cylinders 18 are respectively located at the bottom of the two hollow cylinders 17, and the output shaft of the second cylinders 18 is connected to the piston in the hollow cylinder 17. It should be noted that when the second cylinder 18 and the first cylinder 13 are started, it is necessary to ensure that the PET raw material between the film-forming chamber 11 and the pressing film 22 has been cooled for a period of time and has been shaped, but the temperature has not yet completely dropped. At this time, the second cylinder 18 starts to introduce the liquid (cold water or coolant) in the hollow cylinder 17 through the round hole 111 into the surface of the formed PET product between the film-forming chamber 11 and the pressing film 22, thereby accelerating its heat dissipation and reducing the friction between the formed PET product and the surface of the film-forming chamber 11. After the PET product has cooled down, it will not wear or stick to the inner wall when it is pushed out of the film-forming chamber 11.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
