The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0040] Reference Figures 1 to 5 As shown, a quick-change device for anti-sticking food forming molds includes a frame 1;

[0041] Upper mold 11, which is mounted on the frame 1 via a first driver 12;

[0042] Lower mold assembly 2, which is located directly below the upper mold 11;

[0043] Ejector assembly 3, which is used to eject the food that has been formed inside the lower mold assembly 2;

[0044] and scraping component 13, which is used to scrape off the food ingredients adhering to the ejector component 3;

[0045] The lower mold assembly 2 includes a lower mold 21 and a lower mold base 22 mounted on the frame 1, wherein the lower mold 21 is inserted into the lower mold base 22;

[0046] The ejection assembly 3 includes an ejector post 31 and a second driver 32 for driving the ejector post 31. The lower mold 21 is provided with a mold cavity 211 that cooperates with the ejector post 31. The ejector post 31 scrapes away the food ingredients adhering to the side wall of the mold cavity 211.

[0047] The scraping assembly 13 is mounted on the frame 1 via a third driver 131. The scraping assembly 13 includes a scraper 132 slidably connected to the frame 1. The scraper 132 is used to scrape off the food ingredients adhering to the upper end of the top material column 31.

[0048] Reference Figures 1 to 5 As shown, specifically, the ejector pin 31 extends into the mold cavity 211, and the upper end face of the ejector pin 31 forms the bottom surface of the mold cavity 211, which, together with the mold 11, realizes the molding of food.

[0049] In practice, the ejector pin 31 extends into the mold cavity 211. Then, food ingredients are placed into the mold cavity 211, the first driver 12 is activated, and the lower mold 21 moves downward and extends into the mold cavity 211 to shape the food ingredients in the mold cavity 211.

[0050] After the food is formed in the mold cavity 211, the upper mold 11 moves upward and disengages from the mold cavity 211. The first driver 12 is activated to move the ejector pin 31 upward until the formed food is ejected from the mold cavity 211. During the ejection process, the ejector pin 31 scrapes off the food adhering to the side wall of the mold cavity 211.

[0051] After the food is removed from the ejector pin 31, the ejector pin 31 remains in that position. Then, the third drive 131 operates, pushing the scraper 132 to scrape off the food adhering to the upper end of the ejector pin 31, thereby keeping both the mold cavity 211 and the ejector pin 31 in a clean state, which helps to improve the molding accuracy of the food.

[0052] Finally, the top column 31 and scraper 132 are simultaneously or separately restored to their original positions to prepare for the next molding.

[0053] Understandably, since the lower mold 21 may need to be replaced frequently to mold different switches or different sizes of ingredients, the lower mold 21 is inserted into the lower mold base 22, which makes the replacement of the lower mold 21 very convenient. It is only necessary to remove the old lower mold 21 and insert the new lower mold 21 into the lower mold base 22, thus improving the replacement efficiency of the lower mold 21.

[0054] In some embodiments, the lower mold base 22 is inserted into the frame 1, the frame 1 is provided with a slot 14, and the lower mold base 22 is provided with a insertion ridge 221 that cooperates with the slot 14.

[0055] Reference Figures 1 to 5As shown, in some embodiments, the insert 221 and the lower mold base 22 are an integral structure, and the lower mold base 22 uses its own weight to position the insert 221 within the slot 14. The lower mold base 22 typically has a relatively heavy weight, but no excessive force is required when ejecting food; therefore, the weight of the lower mold base 22 can be used to position the insert 221 within the slot 14 without affecting the positional accuracy of the lower mold base 22 relative to the frame 1.

[0056] In some embodiments, the lower mold base 22 is provided with a positioning groove for positioning the lower mold 21, and the lower mold 21 is provided with a positioning plate 212 that overlaps in the positioning groove. The positioning plate 212 and the lower mold 21 are an integral structure.

[0057] In some embodiments, a positioning pin 15 for positioning the lower mold 21 is provided between the positioning plate 212 and the side wall of the positioning groove. The side wall of the positioning groove and the positioning plate 212 are both provided with pin holes that cooperate with the positioning pin 15. The axis of the positioning pin 15 is perpendicular to the displacement direction of the top material column 31.

[0058] Reference Figures 1 to 5 As shown, there can be one or more locating pins 15. The lower mold 21 is positioned on the lower mold base 22 using locating pins 15. The lower mold 21 has high positional accuracy relative to the lower mold base 22, and the lower mold 21 will not shift upward when ejecting food, thus improving the stability of the lower mold assembly 2. When replacing the lower mold 21, it is only necessary to remove the locating pins 15, making the operation very convenient.

[0059] In some embodiments, the mold cavity 211 extends through the lower mold 21, the lower mold base 22 is cylindrical, and the mold cavity 211 communicates with the inner cavity of the lower mold base 22.

[0060] In some embodiments, the second actuator 32 is a hydraulic cylinder, the hydraulic cylinder includes a piston rod, the ejector pin 31 is mounted on the piston rod, and the second actuator 32 is located inside the lower mold base 22.

[0061] The ejector pin 31 can be snapped onto the piston rod, or it can be fixed to the piston rod by threads. When the lower mold 21 is changed and the ejector pin 31 needs to be replaced at the same time, the ejector pin 31 can be easily replaced. Therefore, the ejector pin 31 should preferably be detachably connected to the piston rod.

[0062] Reference Figures 1 to 5 As shown, in some embodiments, the lower mold base 22 is provided with an inspection port 222, which communicates with the inner cavity of the lower mold base 22. There are multiple inspection ports 222, which are evenly distributed along the circumference of the lower mold base 22.

[0063] The access port 222 is used for maintenance of the second actuator 32. The access port 222 also reduces the manufacturing cost of the lower mold base 22.

[0064] In some embodiments, the frame 1 is further provided with a support plate 16, the scraper assembly 13 is installed on the support plate 16, the support plate 16 is provided with a guide plate, there are two guide plates, a guide cavity is formed between the two guide plates, and the scraper 132 is slidably connected in the guide cavity.

[0065] In some embodiments, both the third actuator 131 and the first actuator 12 are cylinders.

[0066] In some embodiments, the third actuator 131 and the first actuator 12 should not be hydraulic cylinders to prevent leaked oil from contaminating the food.

[0067] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0068] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0069] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
