[0001] This utility model relates to the field of pastry processing equipment, specifically to a pastry pressing and forming tool. Background Technology

[0002] In the food industry, pastries, as a popular food category, boast a rich variety and a wide consumer base. From traditional Chinese pastries such as mooncakes and mung bean cakes to Western-style cakes and cookies, pastry-making techniques have continuously evolved over time. In the pastry industry, molding molds, as key tools determining the appearance and quality of pastries, have a crucial impact on production efficiency and product quality due to their technological level.

[0003] According to the authorization announcement number (CN108495955B), a pastry-making forming tool is provided with a cake-removing mechanism inside the base for removing the formed pastry from the mold. The tool is located on the upper side of the base. When making pastries, the pastry ingredients are placed into the bottom mold. Then, a person presses down a guide rod by holding a pressing plate, causing the top mold to descend. The pastry is then formed by the cooperation between the top and bottom molds.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: When making pastries, the operator pushes the pressing plate to allow the top mold to enter the bottom mold to die-cast the pastries. If the direction of the guide rod movement is slightly deviated, the top mold may get stuck in the bottom mold, making it difficult to push the pressing plate, increasing the labor intensity of the operator and reducing production efficiency.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0027] To more clearly illustrate this invention, the following explanation is provided: When making mung bean cake, the following ingredients are needed: peeled mung beans, unsalted butter, sugar, water, and matcha powder. Soak the peeled mung beans in an appropriate amount of water for 6 hours to allow them to fully absorb water and swell. After soaking, transfer them to a steaming container and steam over medium heat for 40 minutes, until the mung beans are easily mashed by hand. Transfer the steamed mung beans to a food processor, add an appropriate amount of sugar and water, and blend until smooth, forming a fine mung bean paste. Transfer the mung bean paste to a frying container and fry the filling over low heat. During the frying process, gradually add unsalted butter, stirring continuously until the mung bean paste and butter are fully combined and the mixture clumps together; at this point, the filling is initially prepared. Add an appropriate amount of matcha powder to the frying filling and knead thoroughly until the matcha powder and mung bean filling are evenly mixed. Then, place the mixture into a mold to form the desired shape. Example

[0028] Please refer to Figure 1 and Figure 3 In some embodiments of this application, the handle 2 can be flat to facilitate pressing by the operator. Anti-slip textures can be provided on the handle 2 to prevent the operator's fingers from slipping. The mold shell 1 can be cylindrical, with an internal cavity for making mung bean cakes. The bottom of the mold shell 1 is open to facilitate placing the mung bean filling into the cavity. One end of the push rod 3 is connected to the handle 2, and the other end is a spherical structure 9 that passes through the top of the mold shell 1 and extends into the cavity. The outer contour of the pressing plate 8 precisely matches the inner contour of the cavity, exhibiting good shape consistency. A ball groove 10 is provided at the center of the top of the pressing plate 8, and the spherical structure 9 is installed within the ball groove 10. The spherical structure 9 can rotate freely within the ball groove 10, automatically adapting to minor angular deviations between the pressing plate 8 and the mold shell 1. A return spring 5 is sleeved on the push rod 3. One end of the return spring 5 can act on the handle 2, and the other end can act on the mold shell 1.

[0029] Working principle: When making mung bean cakes, a layer of oilcloth can be laid flat on the table. The oilcloth has high-temperature resistance, which can effectively prevent the cakes from sticking and is easy to clean. The prepared mung bean cake filling is kneaded into a ball and placed on the oilcloth. Then, the outer shell 1 of the mold is placed on the filling, so that the filling is inside the cavity. The operator can press the handle 2 with their thumb to overcome the elasticity of the return spring 5 and compress the return spring 5. The handle 2 drives the push rod 3 to move downward, and the push rod 3 drives the pressing plate 8 to move downward. When the pressing plate 8 contacts the filling, it is continuously subjected to pressure, and finally, the filling can be pressed into the preset shape. During the interaction between the push rod 3 and the pressing plate 8, the spherical structure 9 of the push rod 3 is installed in the ball groove 10 of the pressing plate 8, which compensates in real time for stress deviations caused by uneven distribution of filling in the cavity or deformation of the mold shell 1. This rotating connection method can adapt to uneven force caused by uneven distribution of filling and uneven surface of the cavity during the pressing process, avoiding excessive lateral force on the pressing plate 8 locally, thereby effectively preventing the pressing plate 8 from being subjected to large shear stress, extending the service life of the pressing plate 8, and ensuring the molding quality of the pastry. After the external force is removed, the return spring 5 releases the stored elastic potential energy, pushing the push rod 3 and the pressing plate 8 back to the initial position, completing a single pressing cycle.

[0030] In some embodiments of this application, multiple guide members on the sidewall of the pressing plate 8 are respectively installed in multiple guide grooves on the inner wall of the cavity. The cooperation between the guide grooves and the guide members can restrict the pressing plate 8 to move only up and down along the axial direction, ensuring the accuracy of its movement trajectory and preventing the pressing plate 8 from deviating, tilting, or shaking during movement. This ensures that the pressing action can be accurately applied to the filling in the cavity, so that the filling is subjected to uniform pressure, thereby improving the molding accuracy and quality of the product.

[0031] In some embodiments of this application, the surface of the spherical structure 9 may be provided with a PTFE layer, and the surface of the ball socket 10 may be provided with a PTFE layer, thereby reducing the frictional force when the spherical structure 9 and the ball socket 10 rotate relative to each other, making the process of the push rod 3 pushing the pressing plate 8 smoother, reducing energy loss, and making the device operate more efficiently.

[0032] In some embodiments of this application, when pressing the filling, the operator can insert their index and middle fingers into the finger positioning part 7, and then press the handle 2 with their thumb. When the index and middle fingers grip the support base 6, it provides a stable support point for the hand. Using the support base 6 as a fulcrum, the force applied by the thumb is transmitted to the pressing plate 8 through the push rod 3. Compared with the direct force applied by the hand without the mounting bracket, this method more effectively utilizes the lever principle and reduces the required pressing force. Moreover, the support base 6 provides a stable grip point, allowing the operator to more accurately control the direction and force of the push rod 3 when pressing the handle 2, avoiding wasted effort due to hand wobbling or uneven force.

[0033] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the return spring 5 is prone to metal fatigue under prolonged repeated stretching, compression, or torsion under cyclic loads, ultimately leading to a decline in spring performance and aging characteristics such as reduced elasticity and increased deformation. The operator can first remove the handle 2 from the push rod 3 (the handle 2 and push rod 3 can be threaded together), then remove the limiting member 4 from the push rod 3, and finally replace the aged return spring 5 to ensure the device operates normally.

[0034] Please refer to Figure 1 and Figure 2 For example, the straight structure of multiple wedge-shaped blocks 16 can constrain the limiting member 4, allowing the limiting member 4 to abut against the return spring 5 and complete multiple cyclic operations. When the spring needs to be replaced, another limiting member 4 is inserted into the top of the push rod 3 and moved downward along the axial direction of the push rod 3. After the limiting member 4 moves to the predetermined position, it can interact with the inclined structure of the multiple wedge-shaped blocks 16. The mechanical properties of the inclined structure, under the pressure of the limiting member 4, cause the multiple wedge-shaped blocks 16 to be stressed, thereby compressing the first elastic member 15 (which may be a spring). The multiple wedge-shaped blocks 16 finally retract into the first mounting hole 14. At this time, the previously limited limiting member 4 is no longer constrained by the straight structure of the wedge-shaped blocks 16. After the two limiting members 4 are joined together, they can be removed, and finally the aged return spring 5 can be replaced. Without complicated disassembly tools or cumbersome operating procedures, the return spring 5 can be replaced smoothly, greatly improving maintenance efficiency and reducing maintenance costs.

[0035] Please refer to Figure 4 and Figure 5In some embodiments of this application, the push rod 3 includes an adjustable section 11 and a reference section 12. The connection between the adjustable section 11 and the reference section 12 is located above a plurality of wedge-shaped locking blocks 16. The bottom end of the adjustable section 11 is sleeved outside the reference section 12, forming a nested fit structure. The adjustable section 11 can move axially along the reference section 12. The locking member 19 on the outer wall of the reference section 12 can be engaged into the corresponding locking hole 13 of the adjustable section 11, thereby adjusting the overall length of the push rod 3. When the length of the push rod 3 needs to be adjusted again, the operator presses the locking member 19, which presses against the second elastic member 18 (which may be a spring) until the locking member 19 disengages from the corresponding locking hole 13. The operator can then move the adjustable section 11 relative to the reference section 12, causing the locking member 19 to fall into the corresponding locking hole 13, thus completing the adjustment of the length of the push rod 3. The distance between the contact point between the palm and the push rod 3 and the connection point between the push rod 3 and the pressing plate 8 can be considered as the lever arm. Lever arm principle: Adjusting the length of push rod 3 allows operators with different hand sizes to find a comfortable and effortless lever arm length, improving operational convenience and comfort. Ergonomic perspective: A suitable push rod 3 length can better adapt to the natural hand posture and force application habits of different operators.

[0036] For example, the locking member 19 has a guide arc surface on the side away from the second elastic member 18. When the length of the push rod 3 needs to be adjusted, the operator only needs to press the locking member 19 lightly to move the guide arc surface to the locking hole 13. The transition arc structure will contact the edge of the locking hole 13. Due to the smoothness of the arc, the external force can be decomposed into a force that compresses the second elastic member 18 and disengages the locking member 19 from the locking hole 13, thereby making the adjustment process smoother, reducing resistance and jamming during adjustment, and improving the convenience and efficiency of adjusting the length of the push rod 3.

[0037] In some embodiments of this application, the top of the mold shell 1 does not form a seal with the cavity, and the pressing plate 8 is provided with multiple pressure relief and venting holes. The pressure relief and venting holes allow air to be discharged in time during pressing, reducing air resistance. The pressing plate 8 is smoother during the pressing process, reducing the labor intensity of operators and improving work efficiency.

[0038] In summary, the embodiments of this utility model provide a pastry pressing and forming device. During the interaction between the push rod 3 and the pressing plate 8, the spherical structure 9 of the push rod 3 is installed in the ball groove 10 of the pressing plate 8, which compensates in real time for stress deviations caused by uneven distribution of filling in the cavity or deformation of the mold shell 1. This rotating connection method can adapt to uneven force caused by uneven distribution of filling and uneven surface of the cavity during the pressing process, avoiding excessive lateral force on the pressing plate 8 locally, thereby effectively preventing the pressing plate 8 from being subjected to large shear stress, extending the service life of the pressing plate 8, and ensuring the forming quality of the pastry. After the external force is removed, the return spring 5 releases the stored elastic potential energy, pushing the push rod 3 and the pressing plate 8 back to the initial position, completing a single pressing cycle.
