[0002] With continuous economic development and rising living standards, more and more families are keeping pet dogs and cats. Consequently, the variety of pet food on the market is also increasing.

[0003] However, as a relatively new type of product, freeze-dried pet food is still mainly available in single-color cubes, cylinders, or flakes, with limited color and shape options. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mold for producing freeze-dried pet food. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mold for producing freeze-dried pet food includes an annular mold. A first hollow threaded connector is integrally formed at the rear end of the annular mold. A connecting ring is fixedly connected to the outer ring of the first hollow threaded connector near the annular mold. A four-leaf clover mold cylinder is coaxially disposed outside the annular mold, located in front of the connecting ring. The front end of the four-leaf clover mold cylinder is open, and its rear end has a first circular hole adapted to the annular mold. The four-leaf clover mold cylinder is fitted onto the outside of the annular mold through the first circular hole. Feed holes arranged in a circular array at the rear end of the four-leaf clover mold cylinder, corresponding one-to-one with the four inner cavities of the four-leaf clover mold cylinder, are provided. A second hollow threaded connector corresponding one-to-one with the four feed holes is connected to the rear side of the connecting ring. A retaining ring is fixedly connected to the outer ring of the rear end of the four-leaf clover mold cylinder. A fixing cover is disposed outside the four-leaf clover mold cylinder. A second circular hole adapted to the four-leaf clover mold cylinder is horizontally opened on the fixing cover. The fixing cover is fitted onto the outside of the four-leaf clover mold cylinder through the second circular hole. The fixing cover is threadedly connected to the outer ring of the connecting ring.

[0006] Preferably, the rear end of the four-leaf clover mold cylinder is fixedly connected to four guide rods arranged in a ring array. Each guide rod is located between two adjacent feed holes, and the four guide rods and the four feed holes are arranged in a ring array. The connecting ring is horizontally provided with four guide holes arranged in a ring array and adapted to the guide rods. Each guide hole is located between two adjacent second hollow threaded joints, and the four guide holes and the four second hollow threaded joints are arranged in a ring array.

[0007] Preferably, the outer ring of the fixed cover is fixedly connected with a plurality of anti-slip protrusions arranged in a ring array.

[0008] Preferably, a sealing ring is fixedly connected to the front side of the connecting ring, and the sealing ring is made of food-grade silicone rubber.

[0009] Preferably, an annular gasket is fixedly connected to the front side of the retaining ring, and the annular gasket is made of nitrile rubber.

[0010] Preferably, both the annular mold and the four-leaf clover mold cylinder are made of 304 stainless steel.

[0011] Compared with the prior art, this utility model provides a mold for producing freeze-dried pet food, which has the following beneficial effects: 1. This utility model, by setting up an inner and outer ring mold and a four-leaf clover mold cylinder, allows materials of different colors or different raw materials to be conveyed simultaneously. After leaving the mold, the materials are formed into a two-color product with an outer four-leaf clover shape and an inner circle. The two colors can be freely combined to enrich the product appearance, give pet owners a new feeding experience, and make it easier to grab and feed pets, increasing interaction with dogs and cats. At the same time, the ratio of the two layers of materials can be adjusted differently during production design to create a visual functional or flavor combination. In addition, the outer four-leaf clover design has four natural grooves, which makes it easier for dogs and cats to break when chewing, avoiding the formation of large particles that can get stuck in the throat, and preventing problems such as vomiting and indigestion. 2. The annular mold and the four-leaf clover mold cylinder of this utility model adopt a nested connection method, and the two are stably assembled through the threaded connection of the fixing cover and the connecting ring. When the mold needs to be cleaned, the four-leaf clover mold cylinder can be easily separated from the annular mold simply by unscrewing the fixing cover. This effectively avoids the problems of many dead corners and incomplete cleaning of traditional one-piece molds, ensuring that the mold is clean and hygienic to meet pet food production standards. At the same time, this detachable structure also supports the replacement of annular molds and four-leaf clover mold cylinders of different specifications or shapes according to actual production needs. For example, changing to annular molds with different inner diameters can adjust the food forming thickness, or changing to mold cylinders with different numbers and shapes of leaves can produce pet freeze-dried foods with diverse shapes. Multiple production combinations can be achieved without replacing the entire set of molds, which greatly improves the versatility and flexibility of the mold, reduces the equipment investment costs of production enterprises, and improves production efficiency.

Detailed Implementation

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Example 1: Please refer to Figures 1 to 4 As shown, a mold for producing freeze-dried pet food includes an annular mold 1. A first hollow threaded connector 2 is integrally formed at the rear end of the annular mold 1. A connecting ring 3 is fixedly connected to the outer ring of the first hollow threaded connector 2 near the annular mold 1. A four-leaf clover mold cylinder 4 is coaxially disposed outside the annular mold 1, located in front of the connecting ring 3. The front end of the four-leaf clover mold cylinder 4 is open, and its rear end has a first circular hole 5 adapted to the annular mold 1. The four-leaf clover mold cylinder 4 is fitted onto the outside of the annular mold 1 through the first circular hole 5. The rear end of the mold cylinder 4 has feed holes 6 arranged in a ring array and corresponding to the four inner cavities of the four-leaf clover mold cylinder 4. The rear side of the connecting ring 3 is connected to a second hollow threaded connector 7 corresponding to the four feed holes 6. A retaining ring 8 is fixedly connected to the outer ring of the rear end of the four-leaf clover mold cylinder 4. A fixing cover 9 is provided on the outside of the four-leaf clover mold cylinder 4. A second round hole 10 adapted to the four-leaf clover mold cylinder 4 is opened horizontally on the fixing cover 9. The fixing cover 9 is sleeved on the outside of the four-leaf clover mold cylinder 4 through the second round hole 10. The fixing cover 9 is threadedly connected to the outer ring of the connecting ring 3.

[0016] Those skilled in the art will understand that during production, the external feeding device is first connected to four second hollow threaded connectors 7 and one first hollow threaded connector 2. Pet food raw materials enter through the second hollow threaded connectors 7 and then flow evenly into the four inner cavities of the four-leaf clover mold cylinder 4 through the four feeding holes 6. This synchronous and even injection of raw materials into the four inner cavities of the four-leaf clover mold cylinder 4 reduces the material filling time compared to single-hole feeding, significantly improving production efficiency. The threaded connection between the fixed cover 9 and the connecting ring 3, and the coaxial fitting of the annular mold 1 and the four-leaf clover mold cylinder 4, form a stable molding structure, preventing component displacement during raw material injection and freeze-drying, and ensuring the precision and consistency of food molding.

[0017] In addition, the four second hollow threaded joints 7 can be connected to the same five-way joint through connecting pipes, so that material can be supplied by a single feed pipe.

[0018] Example 2: Furthermore, the rear end of the four-leaf clover mold cylinder 4 is fixedly connected to four guide rods 11 arranged in a ring array. Each guide rod 11 is located between two adjacent feed holes 6. The four guide rods 11 and the four feed holes 6 are arranged in a ring array. The connecting ring 3 is horizontally provided with four guide holes 12 arranged in a ring array and adapted to the guide rods 11. Each guide hole 12 is located between two adjacent second hollow threaded joints 7. The four guide holes 12 and the four second hollow threaded joints 7 are arranged in a ring array.

[0019] Those skilled in the art will understand that during production feeding, the cooperation between the guide rod 11 and the guide hole 12 always keeps the relative position of the four-leaf clover mold cylinder 4 and the connecting ring 3 fixed, ensuring that the feed hole 6 and the second hollow threaded joint 7 are precisely aligned, and avoiding blockage of the feed hole 6 or leakage of raw materials due to component misalignment.

[0020] Example 3: Furthermore, the outer ring of the fixed cover 9 is fixedly connected with several anti-slip protrusions 13 arranged in a ring array.

[0021] Those skilled in the art will understand that when assembling the mold, the operator holds the anti-slip protrusion 13 on the outer ring of the fixed cover 9 and twists it. The anti-slip protrusion 13 increases the friction between the hand and the fixed cover 9, preventing the hand from slipping. When disassembling the mold, the anti-slip protrusion 13 is also used to exert force to easily separate the threaded connection between the fixed cover 9 and the connecting ring 3, effectively solving the problem of hand slippage when twisting the fixed cover 9, reducing the force required by the operator, and speeding up the disassembly and assembly of the fixed cover 9, thereby improving the overall operational efficiency of the production process.

[0022] Example 4: Furthermore, a sealing ring 14 is fixedly connected to the front side of the connecting ring 3. The sealing ring 14 is made of food-grade silicone rubber.

[0023] Those skilled in the art will understand that during assembly, the rear end of the four-leaf clover mold cylinder 4 fits against the front side of the connecting ring 3, and the sealing ring 14 is squeezed and filled in the gap between the two, completely preventing material leakage and reducing material loss during the production process. During feeding production, the sealing ring 14 can prevent the material from leaking from the gap between the connecting ring 3 and the four-leaf clover mold cylinder 4. At the same time, the food-grade silicone rubber material avoids contact with the material to generate harmful substances. In addition, the food-grade silicone rubber has good low-temperature resistance and is not easy to harden and crack in the low-temperature environment of the freeze-drying process. It can still maintain the sealing effect after long-term use.

[0024] Example 5: Furthermore, an annular gasket 15 is fixedly connected to the front side of the retaining ring 8. The annular gasket 15 is made of nitrile rubber.

[0025] Those skilled in the art will understand that when the fixing cover 9 is assembled, the rear end of the fixing cover 9 fits against the annular gasket 15. As the fixing cover 9 is screwed onto the connecting ring 3, the annular gasket 15 is compressed. On the one hand, it fills the gap between the fixing cover 9 and the retaining ring 8 to prevent raw materials from leaking from that position; on the other hand, it buffers the impact force when the fixing cover 9 is screwed on, avoiding direct rigid contact between the fixing cover 9 and the retaining ring 8, which would cause wear. In addition, nitrile rubber has excellent oil resistance. If the freeze-dried pet food produced contains oil components, the annular gasket 15 is not easily corroded by oil and can maintain stable performance even after long-term use.

[0026] Example 6: Furthermore, both the ring mold 1 and the four-leaf clover mold cylinder 4 are made of 304 stainless steel.

[0027] Those skilled in the art will understand that during the production process, the 304 stainless steel ring mold 1 can stably withstand the pressure when the raw material is injected, avoiding deformation that affects the shaping accuracy; the four-leaf clover mold cylinder 4, with the structural strength of 304 stainless steel, maintains the stability of the inner cavity shape, and is not prone to rust and corrosion in the low-temperature environment of the freeze-drying process and the water environment of subsequent cleaning, ensuring that the mold condition is consistent for each production.

[0028] The working principle and usage procedure of this device are as follows: First, assemble the mold. The operator holds the four-leaf clover mold cylinder 4, aligns the first round hole 5 at its rear end with the front end of the annular mold 1, and pushes the four-leaf clover mold cylinder 4 along the axis of the annular mold 1 so that the four-leaf clover mold cylinder 4 fits onto the outside of the annular mold 1. At the same time, ensure that the four guide rods 11 at the rear end of the four-leaf clover mold cylinder 4 are inserted into the corresponding four guide holes 12 on the connecting ring 3, until the rear end of the four-leaf clover mold cylinder 4 is tightly fitted with the sealing ring 14 on the front side of the connecting ring 3; then remove the fixing cover 9, and... Align the second round hole 10 on the fixed cover 9 with the front end of the four-leaf clover mold cylinder 4, and fit the fixed cover 9 along the axis of the four-leaf clover mold cylinder 4. Tighten the fixed cover 9 clockwise so that the fixed cover 9 and the outer ring of the connecting ring 3 are gradually screwed together by the threads until the rear end of the fixed cover 9 is in close contact with the annular gasket 15 on the front side of the retaining ring 8 on the outer ring of the rear end of the four-leaf clover mold cylinder 4. After assembly, seal the four second hollow threaded joints 7 and one first hollow threaded joint 2 to the discharge end of the external feeding equipment. Finally, start the feeding equipment to carry out freeze-dried food production operation.
