[0002] Pet food filling molds are professional tools specifically designed for making filled pet food. They are typically made of food-grade plastic or metal, ensuring safety and non-toxicity, and meeting pet food production standards. The mold's internal structure is intricate, with different cavities for filling the outer layer of baked food and the inner core, allowing precise control over the shape and size of the kibble. Common shapes include hearts and bones, increasing pets' interest in eating. By injecting the prepared ingredients into the corresponding cavities and baking them, a beautifully presented and flavorful filled pet food can be created in one piece, meeting pets' nutritional needs while enhancing product quality and market competitiveness.
[0003] In the production of pet baked goods, the performance of the molds plays a crucial role in product quality and production efficiency. Currently, existing molds for filling pet baked goods have significant shortcomings. Firstly, the closing operation of the upper and lower molds is not convenient or efficient, requiring considerable time and labor costs, which not only reduces production efficiency but also increases production costs to some extent. Secondly, after the ingredients are injected, the molding speed is slow, making it impossible to quickly produce baked goods products with attractive appearance and stable shape. Furthermore, due to the poor molding effect, the baked goods fail to meet the standards for appealing to pets in terms of appearance and taste, thus affecting the product's market competitiveness and necessitating improvement.

[0027] The molding mechanism 1 includes a lower mold 11, which is fixedly connected to the top of the support frame 3. An upper mold 12 is placed on the top of the lower mold 11. A second molding groove 14 is opened in the middle of the top of the lower mold 11, and a first molding groove 13 is opened at the bottom of the upper mold 12 corresponding to the second molding groove 14.
[0028] In the molding mechanism 1, the first molding groove 13 of the upper mold 12 corresponds to the second molding groove 14 of the lower mold 11. The injection groove 15 at the bottom of the upper mold 12 is connected to the injection port 5 for easy food injection. After the food is injected, the connecting groove 131 between the first molding grooves 13 ensures even distribution of the food. Simultaneously, the venting groove 16 at the bottom and the venting port 4 at the top of the upper mold 12 allow gas generated during the molding process to escape, preventing molding defects caused by gas accumulation. This design enables the mold to quickly produce aesthetically pleasing and shape-stable baked goods, improving the appearance and taste of the baked goods, making them more appealing to pets, and enhancing the product's market competitiveness.
[0029] The lower mold 11 and the upper mold 12 are respectively provided with a second forming groove 14 and a first forming groove 13 at equal intervals, and a connecting groove 131 is provided between the first forming grooves 13.
[0030] The bottom of the upper mold 12 is provided with an injection groove 15 in the middle of the first molding groove 13. The injection groove 15 is connected to the first molding groove 13. The top of the upper mold 12 is fixedly connected with an injection port 5 corresponding to the injection groove 15.
[0031] The bottom of the upper mold 12 is provided with ventilation grooves 16 on both sides of the first forming groove 13, and the top of the upper mold 12 is fixedly connected with ventilation ports 4 corresponding to the ventilation grooves 16.
[0032] Example 2
[0033] Please see Figure 1-3 Furthermore, based on Embodiment 1, the limiting mechanism 2 further includes a track 21, which is fixedly connected to the front and rear sides of the support frame 3. Sliding blocks 29 are slidably connected to both sides of the track 21. A movable frame 28 is fixedly connected to the top of the sliding blocks 29. A U-shaped clamp 25 is fixedly connected to the top of the movable frame 28. A movable piece 24 is fixedly connected to the front side of the movable frame 28. A ball nut pair 241 is fixedly connected to the middle of the movable piece 24. A bidirectional threaded rod 23 is threadedly connected to the inner ring of the ball nut pair 241. Support blocks 221 are fixedly connected to both ends of the bidirectional threaded rod 23. A motor 22 is fixedly connected to the outer side of the left end of the bidirectional threaded rod 23 on the support block 221. A gear 27 is rotatably connected to the rear side of the movable frame 28. A rack 26 meshes with the bottom of the gear 27. The front side of the rack 26 is fixedly connected to the rear side of the track 21.
[0034] The motor 22 in the limiting mechanism 2 drives the bidirectional threaded rod 23 to rotate. The bidirectional threaded rod 23 engages with the ball nut pair 241, causing the moving piece 24 to move, which in turn allows the moving frame 28 to slide on the track 21. The gear 27 on the rear side of the moving frame 28 meshes with the rack 26 on the rear side of the track 21, further ensuring the stability of the movement. The U-shaped clamp at the top of the moving frame 28 can hold the upper mold 12 and the lower mold 11 tightly. By controlling the forward and reverse rotation of the motor 22, the rapid closing and separation of the upper mold 12 and the lower mold 11 can be easily achieved. This automated mold closing method saves a significant amount of time and labor costs, greatly improving production efficiency and reducing production costs.
[0035] There are two movable frames 28, which are distributed on both sides of the track 21.
[0036] The U-shaped clamp 25 is equipped with a lower mold 11 and an upper mold 12. The motor 22 is equipped with an output shaft, and the motor 22 is fixedly connected to the bidirectional threaded rod 23 through the output shaft.
[0037] In actual operation, when this device is in use, the first forming groove 13 of the upper mold 12 corresponds to the second forming groove 14 of the lower mold 11, and the injection groove 15 at the bottom of the upper mold 12 is connected to the injection port 5 for easy food injection. After the food is injected, the connecting groove 131 between the first forming grooves 13 allows the food to be evenly distributed. At the same time, the venting groove 16 at the bottom of the upper mold 12 and the venting port 4 at the top can discharge the gas generated during the forming process, avoiding forming defects caused by gas accumulation. This design enables the mold to quickly produce baked goods products with beautiful appearance and stable shape, improving the appearance and taste of the baked goods, making them more attractive to pets, and enhancing the product's market competitiveness.
[0038] Motor 22 drives bidirectional threaded rod 23 to rotate. Bidirectional threaded rod 23 engages with ball nut pair 241, driving moving piece 24 to move, which in turn causes moving frame 28 to slide on track 21. The gear 27 on the rear side of moving frame 28 meshes with rack 26 on the rear side of track 21, further ensuring stability during movement. The U-shaped clamp at the top of moving frame 28 can hold the upper mold 12 and lower mold 11 tightly. By controlling the forward and reverse rotation of motor 22, rapid mold closing and separation of the upper mold 12 and lower mold 11 can be easily achieved. This automated mold closing method saves significant time and labor costs, greatly improving production efficiency and reducing production costs.
