[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] See Figure 1 A preferred embodiment of an automatic demolding hydraulic biscuit press is provided. In this embodiment, the hydraulic biscuit press can be used to perform batch pressing of biscuit blanks and automatically demold them after pressing. The demolded biscuit blanks can be quickly collected and transferred through the unloading tray 13.

[0027] Specifically, the main body of the hydraulic briquette press includes a frame 9 as a support and stabilizing structure. The frame 9 has a rectangular horizontal platform 12. The bottom of the horizontal platform 12 is supported by a frame bracket. At the same time, support feet 11 are provided at the four corners of the frame bracket. The support feet 11 have leveling devices to ensure the stability and smoothness of the frame 9 during operation.

[0028] In this embodiment, the platform surface 12 is a rectangular platform surface, and four vertically arranged guide rods 3 are formed at the four corners of the platform surface 12. These guide rods 3 not only provide guidance and limiting functions for the pressing assembly, but also ensure the stability and accuracy of the pressing assembly during the lifting process. The top plane of the guide rod 3 is fixed with a limiting plate 2, which provides top limiting and support for the guide rod 3.

[0029] Between the limiting plate 2 and the horizontal platform 12, a pressing assembly for pressing biscuit blanks is provided. The pressing assembly includes an upper mold body 4 and a lower mold body 5. Both the upper mold body 4 and the lower mold body 5 are plate mold bodies, independently assembled on the guide column rod 3. Under the drive of the driving device, the upper mold body 4 and the lower mold body 5 can achieve stable up and down sliding and position adjustment along the guide column rod 3.

[0030] To ensure that the lifting and lowering of the pressing assembly can be carried out smoothly and accurately, guide sleeves 16 are respectively provided on the outer edges of the four corners of the upper mold body 4 and the lower mold body 5. These guide sleeves 16 are matched with the guide rods 3 and are fitted on the guide rods 3, thereby precisely limiting the sliding trajectory of the upper mold body 4 and the lower mold body 5.

[0031] Meanwhile, the limiting plate surface 2 and the horizontal platform surface 12 can also serve as an assembly platform for drive devices such as hydraulic cylinders, air cylinders, or electric telescopic rods.

[0032] In this embodiment, an upper hydraulic cylinder 1 is selected as the driving device for lifting and lowering the upper mold body 4. The upper hydraulic cylinder 1 is mounted at the center of the limiting plate 2, and its driving part passes through the limiting plate 2 and is connected to the top of the upper mold body 4. When the upper hydraulic cylinder 1 is activated, it can provide a stable driving force, pushing the upper mold body 4 to achieve lifting and lowering movement under the guidance of the guide column 3.

[0033] Meanwhile, in order to achieve the lifting and lowering drive of the lower mold body 5, lower hydraulic cylinders 10 are respectively provided on both sides of the horizontal platform surface 12 in the width direction. The driving parts of these two lower hydraulic cylinders 10 pass through the horizontal platform surface 12 and are assembled and connected to both sides of the bottom surface of the lower mold body 5. When the hydraulic cylinders are started, the lower hydraulic cylinders 10 can provide a stable driving force, pushing the lower mold body 5 to achieve lifting and lowering movement under the guidance of the guide column rod 3, thereby cooperating with the upper mold body 4 to complete the pressing operation of the biscuit blank.

[0034] To facilitate the pressing of biscuit blanks, the lower mold body 5 is equipped with a detachable cavity template 8. Multiple cavities 7 for shaping the biscuit blanks are formed in a regular array on the surface of the template 8. These cavities 7 are all through-hole structures extending vertically. The cavities 7 are mainly used to control the outer contour shape of the biscuit blanks. In actual operation, the cavity template 8 can be quickly replaced according to the different specifications and shapes of the biscuit blanks to meet diverse production needs.

[0035] In this embodiment, the cavity template 8 is assembled as a female mold on the lower mold body 5. To achieve the requirement of detachable assembly of the cavity template 8, a positioning step is formed in the middle of the lower mold body 5, and multiple lower mold fixing buckles 6 are provided in the outer contour area of ​​the positioning step. When disassembling the cavity template 8, first open the lower mold fixing buckles 6, and then push the cavity template 8 out from the lower part of the lower mold body 5. When loading a new cavity template 8, simply place the new cavity template 8 on the positioning step of the lower mold body 5 and fix it with the lower mold fixing buckles 6.

[0036] The bottom surface of the upper mold body 4 is provided with a punch template 17 that matches the cavity 7 on the lower mold body 5. The punches on the punch template 17 are also arranged in a regular array, and the protrusion height of the protrusions 15 on the punches is greater than or equal to the depth of the cavity 7. The protrusions 15 on the punches are mainly used to press the patterns on the surface of the biscuit blank. In actual operation, the protrusions 15 can be easily and quickly replaced by the detachable punch template 17 to meet the pressing requirements of different biscuit surface patterns.

[0037] In this embodiment, the punch template 17 on the upper mold body 4 is a male mold assembly form that matches the cavity template 8 in the female mold assembly of the lower mold body 5. Therefore, the upper mold body 4 only has multiple upper mold fixing buckles 18 at the corresponding outer contour lines of the punch template 17. Through the limiting and fixing effect of the upper mold fixing buckles 18, the punch template 17 can be securely locked in a designated position on the upper mold body 4. At the same time, by twisting the upper mold fixing buckles 18, the punch template 17 can be easily disassembled, thus providing great convenience for replacing punch templates 17 of different specifications.

[0038] In addition, in this embodiment, an insert part is provided on the horizontal platform 12 between the lower mold body 5. The insert part is mainly used to assist the insertion and extraction of the unloading tray 13. The unloading tray 13 matches the insert part. When it is necessary to collect the pressed biscuit blanks, the unloading tray 13 can be pulled out from the insert part by pulling the handle 14 so that the pressed biscuit blanks together with the unloading tray 13 can be transferred to the next process.

[0039] In this embodiment, when the hydraulic briquetting machine is pressing briquetting, the upper mold 4 is first lifted and the lower mold 5 is lowered to the lowest position. When the upper mold 4 is lifted, there is a feeding space between it and the lower mold 5. When the lower mold 5 is lowered to the lowest position, its lower surface is attached to the surface of the unloading tray 13 so as to close the bottom surface of the cavity 7 through the unloading tray 13.

[0040] Subsequently, a fixed amount of dough or other materials to be processed are added one by one into the cavity 7 of the lower mold body 5. After the materials are added, the upper mold body 4 is pressed down. At this time, the protrusions 15 on the punch template 17 are inserted into the corresponding cavities 7, and under the drive of the hydraulic cylinder, a stable pressure is applied to the upper mold body 4, so that the protrusions 15 are in full contact with the dough or other materials to be processed in the cavity 7, achieving uniform pressing of the dough or materials. As the upper mold body 4 continues to press down, the dough or materials are gradually pressed and shaped under the combined action of the protrusions 15 and the cavity 7, forming a biscuit blank with a specific shape, structure and surface pattern.

[0041] After pressing, the lower hydraulic cylinder 10 first drives the lower mold body 5 to rise a short distance, separating the pressed biscuit blank from the cavity 7. Then, the upper hydraulic cylinder 1 and the lower hydraulic cylinder 10 together drive the upper mold body 4 and the lower mold body 5 to rise synchronously. During the rising process, the pressed biscuit blank is completely retained on the surface of the unloading tray 13, thus achieving unloading. At this time, the unloading tray 13 can be pulled out by pulling the handle 14 to transfer the pressed biscuit blank to the next process for further processing.

[0042] In this embodiment, to ensure the safety of food processing, the platform surface 12, the upper mold body 4, and the lower mold body 5 are all made of food-grade stainless steel or food-grade aluminum. These materials not only have good corrosion resistance, but also effectively avoid contamination problems during food processing.

[0043] Meanwhile, to facilitate demolding, food-grade release agent or edible oil can be pre-coated into the cavity 7 of the lower mold body 5 as a release agent. At the same time, the protrusions 15 on the punch can also be made of food-grade Teflon material to ensure that the biscuit blanks do not stick during the pressing process, thereby further improving the safety and hygiene of food processing.
