[0030] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0031] like Figures 1 to 3 As shown, this embodiment provides a three-dimensional product forming and shaping device, including:

[0032] A mold, wherein a mold cavity 11 with an opening at the bottom is provided at the bottom, and a refrigeration cavity 3 is provided inside the mold; at least two vertical cylinders 12 are provided in the refrigeration cavity 3 to connect the cavity top and cavity bottom of the refrigeration cavity 3, and an upper vent hole 121 and a lower vent hole 122 connected up and down are formed in the vertical cylinder 12, the aperture of the lower vent hole 122 is smaller than the aperture of the upper vent hole 121, and the lower vent hole 122 extends downward to communicate with the mold cavity 11; a guide hole 21 communicating with the upper vent hole 121 is provided at a position corresponding to each vertical cylinder 12 on the top surface of the mold;

[0033] The shaping needle 4 can be inserted into the corresponding guide hole 21 and the vertical tube 12 so as to slide up and down;

[0034] The driving structure 5 is connected to the shaping needle 4 and can drive the shaping needle 4 to slide back and forth between the first position and the second position; when the shaping needle 4 is located at the first position, the bottom end of the shaping needle 4 is located in the upper vent 121; when the shaping needle 4 is located at the second position, the bottom end of the shaping needle 4 is located in the lower vent 122, and the bottom surface of the shaping needle 4 can form a molding surface with the cavity wall surface of the mold cavity 11.

[0035] It can be understood that the cavity wall surface of the mold cavity 11 is a non-planar surface with a three-dimensional pattern, which can be used to mold products with three-dimensional patterns, such as ice cream with a three-dimensional pattern. Generally, the aperture of the guide hole 21 is the same as the aperture of the lower vent hole 122. The shaping needle 4 is a slender cylindrical rod, and has a clearance fit with the guide hole 21 and the lower vent hole 122, and the clearance is small; the guide hole 21 can guide the shaping needle 4. The aperture of the upper vent hole 121 is larger than the diameter of the shaping needle 4, and there is a preset gap between the two. The bottom surface of the shaping needle 4 is a non-planar surface, and its shape is consistent with the cavity wall surface of the mold cavity 11. During processing, the lower end surface of the shaping needle 4 needs to be processed in coordination with the mold cavity 11, so that when the shaping needle 4 is in the second position, its bottom surface can be spliced ​​with the cavity wall surface of the mold cavity 11 to form a complete molding surface, ensuring that the overflow liquid is returned to its position while the three-dimensional pattern of the product remains intact.

[0036] Usually the shaping needle 4 is located at the first position, such as Figure 1As shown, the bottom end of the shaping needle 4 is located in the upper vent hole 121. During use, when molding a product, the mold, the shaping needle 4 and the drive structure 5 form a whole that moves downward toward the product liquid, and at the same time, a cooling medium is introduced into the refrigeration chamber 3 to facilitate the rapid freezing and molding of the liquid. In the process of the liquid entering the mold cavity 11, because the shaping needle 4 is in the first position, the gas in the mold cavity 11 can be discharged in sequence through the lower vent hole 122, the gap between the upper vent hole 121 and the shaping needle 4, and the gap between the guide hole 21 and the shaping needle 4, so as to achieve exhaust during the product molding process and ensure that the liquid completely fills the mold cavity 11. When the mold descends to the lowest position and the product is formed, the drive structure 5 drives the shaping needle 4 to quickly descend to the second position (as shown in FIG. Figure 2 As shown in the figure, the mold is then quickly returned to the first position, so that the liquid material overflowing into the upper vent hole 121 returns to the mold cavity 11 and merges with the liquid material of the product, thereby preventing vacuum from being generated during the demolding process and affecting the demolding of the product.

[0037] Therefore, the shaping device in this embodiment changes the existing structural mode of setting a refrigeration box above the mold, designs the interior of the mold as a hollow structure, forms a refrigeration cavity 3 therein, and distributes cooling medium around the vertical cylinder 12 to ensure that the mold contacts the cooling medium over as large an area as possible, thereby increasing the contact area between the cooling medium and the mold, making the mold cooling more uniform, increasing the cold storage capacity of the mold, achieving a better effect on the rapid freezing and molding of the slurry, and ensuring the stability of product molding. An exhaust channel consisting of a lower air vent 122, an upper air vent 121 and a guide hole 21 and a shaping needle 4 that can move up and down are added to the mold. When the shaping needle 4 is in the first position, the exhaust channel can be connected to the outside world, exhaust can be discharged during the product compression molding, and vacuum release can be performed during the product demoulding process to ensure smooth product demoulding; when the shaping needle 4 is in the second position, the shaping needle 4 and the lower air vent 122 form a clearance fit, which can return the overflowed material and will not remain in the exhaust channel, thereby avoiding blockage of the exhaust channel, and effectively ensuring the quality and stability of product molding, and ensuring that the product is fully molded; at the same time, the aperture of the upper air vent 121 is larger than the aperture of the lower air vent 122 (that is, the upper part adopts coarse holes and the lower part adopts fine holes), which is also easier to exhaust.

[0038] The device of this embodiment enables product forming technology to break through technical barriers, realizes the industrialized production of three-dimensional ice cream products on the tunnel line, opens up a new ice cream category, brings technological breakthroughs to the development of the industry, and enables consumers to have a brand new product experience.

[0039] In a specific implementation, in order to facilitate processing and installation, the mold includes:

[0040] The mold body 1 has a mold cavity 11 formed at the bottom and a groove formed at the top. A vertical cylinder 12 is formed by protruding upward from the bottom of the groove.

[0041] The mold cover 2 is detachably mounted on the top of the mold body 1 and encloses the groove to form a refrigeration cavity 3; the guide hole 21 is opened on the mold cover 2, and the top of the vertical cylinder 12 is inserted and fixed in the mold cover 2. Each vertical cylinder 12 can be integrally formed with the mold body 1, and the mold cover 2 can be connected to the mold body 1 by fasteners (such as screws).

[0042] Preferably, in order to reduce the difficulty of processing and installation, the bottom driving end of the driving structure 5 is connected to a mounting block 6, and a mounting groove 61 is provided at the bottom of the mounting block 6. The top end of the shaping needle 4 can be suspended in the mounting groove 61 in an up-and-down and circumferentially floating manner.

[0043] Reference Figure 1 The notch of the mounting groove 61 is arranged downward, and a limiting ring 611 with a reduced diameter is formed at the notch position. A limiting block 41 with an increased diameter is provided at the top of the shaping needle 4. The limiting block 41 is installed in the mounting groove 61, and there is a floating gap between the limiting block 41 and the mounting groove 61 in the vertical direction and the circumferential direction of the shaping needle 4. Specifically, the vertical thickness of the limiting block 41 is smaller than the distance between the bottom of the mounting groove 61 and the limiting ring 611, and the diameter of the limiting block 41 is smaller than the horizontal width of the mounting groove 61, so that the limiting block 41 can float in any direction of up, down, left, right, front and back in the mounting groove 61; the inner diameter of the limiting ring 611 is larger than the diameter of the shaping needle 4 and smaller than the diameter of the limiting block 41, so as to limit the limiting block 41.

[0044] If the top of the shaping needle 4 is fixedly connected to the mounting block 6, the axes of the shaping needle 4, the guide hole 21 and the lower vent hole 122 need to be on the same straight line during installation, which requires high processing and installation accuracy and is difficult to process and install. In this embodiment, the top of the shaping needle 4 and the mounting block 6 are connected in a floating manner, and it is only necessary to ensure that the axes of the guide hole 21 and the lower vent hole 122 are on the same straight line, and the center line of the shaping needle 4 does not need to be completely aligned with the former two, which greatly reduces the difficulty of processing and installation.

[0045] In addition, since there are multiple shaping needles 4, the axes of the shaping needles 4 must be parallel to ensure stable operation during the up and down movement. If the top of the shaping needle 4 is fixedly connected to the mounting block 6, it is easy to cause a jam due to the non-parallel axes of the shaping needles 4, affecting the work. In this embodiment, the shaping needles 4 are connected in a floating manner, and there is no need to require the axes of the shaping needles 4 to be parallel, which effectively prevents the shaping needles 4 from jamming during the movement process.

[0046] Furthermore, to facilitate processing and installation, the mounting block 6 includes a connecting block 62 and a driving block 63 which are arranged up and down and detachably connected. The driving end of the driving structure 5 is connected to the connecting block 62 , and the mounting groove 61 is opened on the driving block 63 .

[0047] The connection block 62 and the driving block 63 can be connected by fasteners (such as screws). The mounting block 6 preferably adopts a cold-insulating block. The cold-insulating material can prevent the cold from being transferred to the driving structure 5 and causing abnormal operation of the driving structure 5 during continuous production, thereby ensuring stable operation of the driving structure 5 during continuous production.

[0048] Preferably, at least two slots 22 are provided on the bottom surface of the mold cover body 2, the top end of the vertical tube 12 can be clamped in the corresponding slots 22, and a first sealing ring 23 is clamped between the top end of the vertical tube 12 and the bottom of the slot 22; a second sealing ring is clamped between the bottom periphery of the mold cover body 2 and the top periphery of the mold main body 1.

[0049] The inner diameter of the first sealing ring 23 is the same as the aperture of the upper vent hole 121. The first sealing ring 23 can prevent the cooling medium from leaking out of the exhaust channel, thereby reducing the amount of cooling medium used. The refrigeration cavity 3 in the entire mold adopts a sealed structure, which more effectively prevents the cold in the refrigeration cavity 3 from overflowing, thereby reducing the consumption of cooling medium.

[0050] The cooling medium introduced into the refrigeration cavity 3 can be selected as needed. In this embodiment, the refrigeration cavity 3 is preferably filled with liquid nitrogen, and the cooling medium introduced therein is liquid nitrogen. Accordingly, the mold is provided with a liquid inlet 24 and an exhaust port 25 that can be connected to the refrigeration cavity 3. Generally, a liquid inlet joint 241 and an exhaust joint 251 are connected to the liquid inlet 24 and the exhaust port 25, respectively. Liquid nitrogen enters the mold from the liquid inlet 24, and nitrogen is discharged from the exhaust port 25.

[0051] The axes of the vertical cylinders 12 are directly opposite to the highest point of the mold cavity 11 of the mold corresponding to the product shape, and the place where air pockets are easily formed when the die is pressed to form the product, which can better prevent the occurrence of air pockets when the product is formed.

[0052] Furthermore, this embodiment also provides a die pressing device, including a stamping drive device and the above-mentioned three-dimensional product forming and shaping device; the stamping drive device is connected to both the mold and the driving structure 5, and can drive the mold and the driving structure 5 to move up and down together.

[0053] When in use, the stamping drive device drives the mold, shaping needle 4 and driving structure 5 to move downward toward the product liquid to achieve product molding. The specific working principle has been described above. The die pressing device includes the above-mentioned three-dimensional product molding shaping device and has the same effect, which will not be repeated here.

[0054] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
