[0001] This utility model relates to the field of polyurethane foaming technology, specifically to a multi-end foaming and casting device for orthopedic models. Background Technology

[0002] This is a specialized equipment for polyurethane foam injection molding. As long as the performance indicators of the polyurethane components (isocyanate and polyether polyol) meet the formulation requirements, this equipment can produce uniform and qualified foam products. It produces foam plastic through a chemical reaction between polyether polyol and polyisocyanate in the presence of various chemical additives such as foaming agents, catalysts, and emulsifiers.

[0003] When making orthopedic models, a polyurethane foaming machine or a polyurethane foaming machine with specific functions is required. Generally, it is done manually by hand, pouring the foam into the mold through a mixing head. After pouring, the mold is sealed to prevent the foam from overflowing. Because the polyurethane foaming agent remains stationary in the mold, the foaming is uneven, and the product model is prone to problems such as cracks, shrinkage, brittleness, and softness, which affects the product's pass rate and quality. Summary of the Invention

[0004] To address the above deficiencies, this utility model provides a multi-end foaming and casting device for orthopedic models to solve the problem of uniform foaming of foaming agent.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Please refer to Figures 1 to 8. This application provides a multi-end foaming and casting device for orthopedic models, including a foaming machine 1 and a foam mold frame 2. The upper end of the foam mold frame 2 is connected to a swing frame 3 via a swing mechanism. A mold 4 is installed on the swing frame 3. The swing mechanism includes a set of rotating shafts 5, a mounting plate 6, a servo cylinder 7, a sliding rod 8, a rack 9, and a fan-shaped tooth 10. The set of rotating shafts 5 is movably inserted into the upper end of the foam mold frame 2 via fastening bearings and is respectively connected to the bottom of the swing frame 3. The mounting plate 6 is installed at the bottom front end of the foam mold frame 2. The servo cylinder 7 is horizontally installed on the mounting plate 6. The sliding rod 8 is installed on the telescopic end of the servo cylinder 7. The rack 9 is opened on the sliding rod 8. The fan-shaped tooth 10 is installed on the front rotating shaft 5 and its bottom meshes with the rack 9.

[0025] In this embodiment, the foaming machine 1 is manually operated, and the foaming agent is poured into the mold 4 from multiple ends through the mixing head. This is existing technology. When swinging, the extension end of the servo cylinder 7 extends, driving the sliding rod 8 to move to the right. Through the rack 9, the fan-shaped tooth 10 is deflected. A set of rotating shafts 5 drives the mold 4 to deflect through the swing frame 3. As shown in Figure 4, the reciprocating extension and retraction of the servo cylinder 7 realizes the swinging of the mold 4, which can make the foaming agent in the mold 4 foam evenly, prevent the product model from easily cracking, shrinking, brittle, and soft, and improve the product qualification rate and quality.

[0026] In some embodiments, an opening and closing mechanism is connected to the upper end of the mold 4.

One end of the connecting rod 16 is hinged to the connecting frame 14, and the other end is hinged to the second corner seat 15.

[0027] When the extension end of servo cylinder 11 extends, it pushes the n-shaped pusher 12 to the right and causes the connecting frame 14 to deflect. The connecting frame 14, through the connecting rod 16, can automatically open the mold 4 to facilitate the pouring of foaming agent, as shown in Figure 8. Conversely, when the extension end of servo cylinder 11 retracts, it causes the n-shaped pusher 12 to move to the left. The connecting frame 14, through the connecting rod 16, can automatically close the mold 4, as shown in Figure 2, to facilitate foaming.

[0028] In some embodiments, a set of limiting plates 17 corresponding to the n-type push frame 12 are installed on the swing frame 3. The set of limiting plates 17 is used to limit the position of the n-type push frame 12, as shown in FIG8.

[0029] In some embodiments, the mold 4 includes a bottom mold and a top mold, and the left end of the top mold is hinged to the bottom mold, as shown in FIG6.
