DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0027] An embodiment of the present application provides a mold that can be used to make pressed products. The pressed products may include pressed teas such as tea cakes, and may also include molded foods such as moon cakes and seaweed cakes. The embodiment of the present application will be explained using pressed teas such as tea cakes as an example. Other moon cakes, etc. can refer to the instructions for pressed tea and will not be repeated in the specification.

[0028] It is known that pressed tea is a general term for tea with specific shapes such as tea cakes, tea bricks, leaf shapes, copper coin shapes, ingot shapes, and heart shapes, which are made by pressing loose tea leaves into molds.

[0029] Please refer to Figure 1 and Figure 2 The mold provided in the embodiment of the present application includes a lower mold 100, an ejector mold 200, a shell 300 and an isolation member 400. The lower mold 100 is provided with a lower mold cavity 110 and a mounting hole 120 ( Figure 5 ), the mounting hole 120 passes through the bottom wall of the lower mold cavity 110. It can be understood by those skilled in the art that the shape of the lower mold cavity 110 is related to the shape of the tea cake 20 to be made. For example, if the required tea cake 20 is square, the lower mold cavity 110 can be a square groove; if the required tea cake 20 is round, the lower mold cavity 110 can be round. The specific shape of the lower mold cavity 110 is not limited in the embodiment of the present application. It can also be understood by those skilled in the art that the mounting hole 120 is located in the middle position of the lower mold cavity 110. In this way, the ejection mold 200 can be located in the middle position of the lower mold cavity 110, thereby ensuring that the tea cake 20 is evenly stressed when the ejection mold 200 is ejected, thereby avoiding deviation of the tea cake 20 when ejected.

[0030] Those skilled in the art will also understand that there can be multiple ejector molds 200. When there are multiple ejector molds 200, there can also be multiple mounting holes 120. It should be noted that when there are multiple ejector molds 200, the ejector molds 200 should generally be distributed symmetrically around the center point of the lower mold cavity 110. This is to ensure that the ejection force exerted by the ejector molds 200 on the tea cake 20 is balanced during ejection, ensuring that the tea cake 20 can be ejected in a vertical direction, and preventing the tea cake 20 from colliding with the lower mold 100 or the housing 300 during the ejection process, which may damage the shape of the tea cake 20.

[0031] The shell 300 is provided with a accommodating cavity 310 and an upper opening and a lower opening connected to the accommodating cavity 310. The bottom of the shell 300 is fixed to the top of the lower mold 100, and the lower opening is opposite to the opening of the lower mold cavity 110. Specifically, the shell 300 can be fixed to the lower mold 100 by bolts, etc., and the embodiment of the present application does not impose specific restrictions. It should be noted that the lower opening of the accommodating cavity 310 should be consistent with the opening shape of the lower mold cavity 110. In this way, it can be ensured that the tea leaves 10 in the accommodating cavity 310 can all enter the lower mold cavity 110 when being pressed, and can be evenly pressed by the upper mold 600.

[0032] The isolating member 400 covers the bottom wall and the side wall of the lower mold cavity 110 to isolate the accommodating cavity 310 from the lower mold cavity 110. It will be understood by those skilled in the art that the isolating member 400 can be a non-elastic material such as isolation paper or isolation cloth, or can be an elastic material such as a silicone pad. However, it should be noted that when the isolating member 400 is a non-elastic material such as isolation paper or isolation cloth, each time before adding tea leaves to the accommodating cavity 310, it is necessary to lay the isolation paper or isolation cloth on the bottom wall and the side wall of the lower mold cavity 110, and then place the tea leaves into the accommodating cavity 310. In this way, the isolation paper and isolation cloth can isolate the tea leaves in the accommodating cavity to prevent the tea leaves from entering the gap of the lower mold 100. However, when the tea leaves 10 in the accommodating cavity 310 are pressed, the ejection mold 200 will eject the isolation paper or isolation cloth together during the demoulding process. The next time the mold is used to press the tea leaves, it is necessary to re-lay the isolation paper or isolation cloth on the bottom wall and side wall of the lower mold cavity 110. That is to say, when the isolation member 400 is made of non-elastic materials such as isolation paper or isolation pads, the isolation member 400 needs to be re-laid and replaced each time. Although it can prevent the tea leaves 10 or tea residues from falling into the gap of the lower mold 100, it is relatively troublesome to use.

[0033] Therefore, in the embodiment of the present application, the isolator 400 is preferably made of an elastic material such as a silicone pad. The periphery of the isolator 400 is fixed between the shell 300 and the lower mold 100. The isolator 400 is elastic. Specifically, the isolator 400 can be made of elastic materials such as rubber and silicone. In the embodiment of the present application, silicone is preferably used. The use of silicone can also prevent tea leaves from sticking to the isolator 400. In addition, the flexibility of silicone makes the pressed tea closer to artificial production, thereby increasing the quality of the pressed tea.

[0034] It is understandable that the isolation piece 400 can be directly crimped between the shell 300 and the lower mold 100, or can be bonded to the outer wall of the shell 300, or additional clips can be provided on the outer wall of the shell 300 to fix the isolation piece 400.

[0035] Of course, it can be understood by those skilled in the art that the isolator 400 can also be fixed on the lower mold 100, for example, a mounting slot can be provided in the lower mold 100 at a position surrounding the lower mold cavity 110. The specific fixing method of the isolator 400 can be fixed by those skilled in the art according to actual conditions, and the embodiments of the present application do not impose specific restrictions. Specifically in the embodiments of the present application, the isolator 400 is preferably fixed on the lower mold 100, so that when the isolator 400 needs to be replaced, the isolator 400 can be fixed on the lower mold 100 in advance, and then the outer shell can be fixed on the upper mold 600, thereby increasing the convenience of replacing the isolator 400. It can be understood by those skilled in the art that the isolator 400 is an elastic member and can be used multiple times, so that it does not need to be replaced every time the tea leaves 10 are pressed, thereby reducing labor intensity. However, it should also be known that after the isolation member 400 has been used a certain number of times, damage will inevitably occur. Therefore, the isolation member 400 can be regarded as a consumable, and consumables are products that need to be replaced frequently. Therefore, in the embodiment of the present application, by fixing the isolation member 400 on the lower mold 100, the convenience of replacing the isolation member 400 can be increased.

[0036] The ejector mold 200 is disposed in the mounting hole 120 and is positioned below the spacer 400. The upper surface of the ejector mold 200 is flush with the bottom surface of the lower mold cavity 110. This arrangement prevents the upper surface of the ejector mold 200 from interfering with the shaping of the tea cake 20. Those skilled in the art will appreciate that the flushing of the upper surface of the ejector mold 200 with the bottom surface of the lower mold cavity 110 here should be understood to mean that the upper surface of the ejector mold 200 and the bottom surface of the lower mold cavity 110 together constitute the bottom shape of the tea cake 20.

[0037] The ejector mold 200 is movable along the axial direction of the mounting hole 120 and extends at least partially into the lower mold cavity 110. The ejector mold 200 is capable of causing the spacer 400 to deform. It is understood that during the demolding process, the ejector mold 200 ejects the tea cake 20 from the lower mold cavity 110, thereby completing the demolding of the tea cake 20. Those skilled in the art can also understand that, in the process of the tea leaves 10 being pressed into the tea cakes 20, the isolating member 400 will adhere to the side wall surface, the bottom wall surface and the upper surface of the ejector mold 200 of the lower mold cavity 110 under the action of pressure; in the process of demoulding the ejector mold 200, the upward movement of the ejector mold 200 will drive the isolating member 400 to move upward. Since the isolating member 400 is elastic, the isolating member 400 will not be damaged during this process, and the isolating member 400 will be deformed, that is, the isolating member 400 can still isolate the space where the tea cake 20 is located from the space where the ejector mold 200 is located, thereby preventing tea debris from falling into the space where the ejector mold 200 is located. In this way, it can be ensured that the ejector mold 200 can be smoothly reset after the ejection is completed, thereby ensuring the quality of the tea cake 20.

[0038] refer to Figure 3 、 Figure 4 and Figure 5 In the embodiment of the present application, when the tea leaves 10 need to be pressed, the tea leaves 10 are first placed in the accommodating cavity 310 of the housing 300. At this time, due to the presence of the separator 400, the tea leaves 10 will not fall onto the wall surface of the lower mold cavity 110. Since the separator 400 is elastic, during the pressing process, the separator 400 will deform as the pressure increases, and thus will not hinder the pressing and forming of the tea cake 20. After the tea leaves 10 are pressed into the tea cake 20, the separator 400 is located between the bottom of the tea cake 20 and the bottom wall of the lower mold cavity 110. The ejector mold 200 then lifts the tea cake 20 located above the separator 400 and ejects the tea cake 20 from the lower mold cavity 110. Since there is an isolation piece 400 between the tea leaves 10 and the wall surface of the lower mold cavity 110 for isolation during the entire molding process of the tea cake 20, the tea leaves 10 and the tea leaves 10 powder will not fall onto the wall surface of the lower mold cavity 110 during the molding process of the tea cake 20. Therefore, the tea leaves 10 and the tea leaves 10 powder will not fall into the mounting hole 120. Therefore, when the ejection mold 200 ejects the tea cake 20, no tea leaves 10 will fall into the mounting hole 120. Therefore, after the ejection is completed, the ejection mold 200 can be smoothly reset to the mounting hole 120, and the upper surface of the ejection mold 200 can be ensured to be flush with the bottom surface of the lower mold cavity 110, thereby ensuring the molding quality of the tea cake 20.

[0039] In some embodiments, the isolation member 400 is partially adhered to the upper surface of the ejector mold 200. It will be understood by those skilled in the art that the isolation member 400 can be adhered to the upper surface of the ejector mold 200 by adhesive or the like. Specifically, the ejector mold 200 is first moved so that the upper surface of the ejector mold 200 is flush with the opening of the lower mold cavity 110, and then the isolation member 400 is adhered to the upper surface of the ejector mold 200 by adhesive, and then the periphery of the isolation member 400 is fixed to the lower mold 100, and finally the ejector mold 200 is reset. Since the isolation member 400 is elastic, the isolation member 400 can be deformed during the resetting process of the ejector mold 200, thereby preventing the isolation member 400 from being damaged. Adhesion can facilitate operation. In the embodiment of the present application, the spacer 400 is bonded to the upper surface of the ejection mold 200 to ensure that the central area of ​​the spacer 400 is flat, thereby ensuring that the spacer 400 as a whole is as flat as possible, and preventing the bottom structure of the tea cake 20 from being altered due to wrinkles in the spacer 400. Those skilled in the art will also understand that in the embodiment of the present application, the area of ​​the upper surface of the ejection mold 200 can be larger. For example, the area of ​​the upper surface of the ejection mold 200 can be more than half the area of ​​the bottom surface of the lower mold cavity 110. In this way, the area of ​​the spacer 400 bonded to the ejection mold 200 can be increased, thereby preventing the spacer 400 from deforming unevenly and wrinkling, which could result in an irregular bottom of the tea cake 20. This improves the forming state of the tea cake 20 and enhances the forming quality of the tea cake 20.

[0040] In some embodiments, the mounting hole 120 is a stepped hole. When the lower surface of the ejector mold 200 is in contact with the stepped surface of the stepped hole, the upper surface of the ejector mold 200 is flush with the bottom surface of the lower mold cavity 110. In this embodiment of the present application, the stepped hole can support the ejector mold 200. In this way, during the pressing process of the tea leaves 10, the ejector mold 200 no longer needs to provide additional support force, and the stepped surface of the stepped hole can be used. Moreover, by supporting the ejector mold 200 on the stepped surface, the upper surface of the ejector mold 200 can also be ensured to be flush with the bottom surface of the lower mold cavity 110, thereby ensuring the molding quality of the tea cake 20.

[0041] In some embodiments, reference Figure 4The mold further includes a spring plunger 500. The ejector mold 200 includes an ejection portion 210 and a connecting portion 220 that are fixedly connected. The diameter of the ejection portion 210 is larger than the diameter of the connecting portion 220, and the upper surface of the ejection portion 210 is flush with the bottom surface of the lower mold cavity 110. The mounting hole 120 includes a first hole and a second hole that are interconnected. The diameter of the first hole is larger than the diameter of the second hole. The ejection portion 210 is located in the first hole, and the connecting portion 220 is located in the second hole. The connecting portion 220 is radially provided with a blind hole. The spring plunger 500 is disposed in the blind hole, and the opposite ends of the spring plunger 500 respectively abut against the bottom wall of the blind hole and the peripheral wall of the second hole.

[0042] Specifically, the spring plunger 500 includes a spring and a push rod. The two ends of the spring are fixedly connected to the push rod and the bottom wall of the blind hole, respectively. The end of the push rod facing away from the spring is a spherical head. When the push rod is in the second hole, the spring is in a compressed state, so the push rod presses against the peripheral surface of the second hole. This prevents the ejector mold 200 from shaking in the mounting hole 120. It will be understood that the connection between the first hole and the second hole is also chamfered to facilitate the push rod to slide from the first hole into the second hole.

[0043] Those skilled in the art will also appreciate that there may be multiple spring plungers 500, evenly distributed along the circumference of the connecting portion 220, and on the same circumferential surface. This arrangement ensures that the ejector mold 200 is subjected to a balanced force. Furthermore, by providing multiple spring plungers 500, the ejector mold 200 can be stably positioned in the stepped hole.

[0044] Please refer to Figure 7 In some other embodiments, the mounting hole 120 is a tapered hole, and the ejector mold 200 is provided with a tapered surface corresponding to the tapered hole. In the embodiment of the present application, the tapered hole on the mounting hole 120 cooperates with the tapered surface of the ejector mold 200, so that the lower mold 100 can support the ejector mold 200. The mounting hole 120 is set as a tapered hole to facilitate the positioning of the ejector mold 200. The tapered hole can also prevent the ejector mold 200 from shaking in the mounting hole 120, thereby ensuring that the ejector mold 200 can be accurately reset each time after ejecting the tea cake 20, ensuring that the upper surface of the ejector mold 200 is flush with the bottom wall surface of the lower mold cavity 110, so that the obtained tea cake 20 can be guaranteed to be of higher quality.

[0045] In some embodiments, the inner diameter of the accommodating cavity 310 gradually increases from the lower opening to the upper opening. In this embodiment of the present application, due to the presence of the separator 400, to avoid permanent deformation of the separator 400 and increase its service life, the deformation of the separator 400 should not be too large. In this embodiment of the present application, to ensure that the tea leaves 10 in the accommodating cavity 310 are sufficient to compress the tea cake 20, the height of the accommodating cavity 310 is generally relatively high. The specific height can be determined by those skilled in the art based on the specific weight and shape of the tea cake 20. After the tea cake 20 is formed, the deformation of the separator 400 limits the ejection mold 200 from being too high. Therefore, the ejection mold 200 cannot eject the tea cake 20 from the upper opening of the accommodating cavity 310. In this embodiment of the present application, because the separator 400 is located between the housing and the lower mold 100, the ejection mold 200 can push the tea cake 20 into the accommodating cavity 310 without causing permanent deformation and failure of the separator 400. In order to facilitate the removal of the tea cake 20 pushed into the accommodating cavity 310, the accommodating cavity 310 in the embodiment of the present application is configured to have an inner diameter that gradually increases from the lower opening to the upper opening. That is, when the tea cake 20 enters the accommodating cavity 310, a gap will appear between the tea cake 20 and the interior of the accommodating cavity 310. This gap can facilitate the removal of the tea cake 20 from the accommodating cavity 310, thereby avoiding damage to the tea cake 20 and deformation and failure of the isolating member 400, thereby extending the service life of the isolating member 400.

[0046] In some embodiments, the mold further includes an upper mold 600, which is positioned above the lower mold 100 and capable of passing through the accommodating cavity 310 and closing with the lower mold 100. In this embodiment, the upper mold 600 compresses the tea leaves 10 in the accommodating cavity 310 and ultimately forms the tea leaves. During the pressing process, the presence of the separator 400 prevents debris from contacting the walls of the lower mold cavity 110.

[0047] In some embodiments, reference Figure 1 and Figure 2 The upper mold 600 includes a template 610 and a forming mold 620. The forming mold 620 is fixedly connected to the side of the template 610 facing the lower mold 100, and the side of the forming mold 620 facing the lower mold 100 is provided with a forming cavity 621. It can be understood by those skilled in the art that the forming cavity 621 is designed according to the shape of the tea cake 20. For example, if the tea cake 20 is square, the forming cavity 621 can be a plane; for example, if the tea cake 20 is in a shape with one side convex, a corresponding groove can be set in the forming cavity 621. In the embodiment of the present application, since the top of the tea cake 20 is an arc-shaped convexity, the forming cavity 621 is set as an arc-shaped groove.

[0048] Those skilled in the art will understand that, in the embodiment of the present application, setting the special-shaped mold cavity on the upper mold 600 as the molding cavity 621 can make the lower mold cavity 110 a regular pattern, thereby facilitating the setting of the upper surface of the ejection mold 200, thereby reducing the difficulty of manufacturing the mold.

[0049] In some embodiments, an elastic spacer 640 is provided on the side of the forming mold 620 facing the lower mold 100. Those skilled in the art will appreciate that the elastic spacer 640 can be a silicone pad that completely covers the side of the forming mold 620 facing the lower mold. Specifically, it can be secured using adhesives or other methods, or by providing a slot in the peripheral wall of the forming mold 620. This embodiment of the present application is not particularly limited, but it should be noted that the elastic spacer 640 should be in close contact with the side of the forming mold 620 facing the lower mold 100 to ensure an intact surface of the pressed tea leaves during molding. In this embodiment of the present application, when the forming mold 620 molds the tea leaves 10 in the accommodating cavity 310, the elastic spacer 640 contacts the tea leaves 10. Due to the elasticity of the elastic spacer 640, the pressed tea leaves are more similar to hand-made tea cakes and have higher quality. Furthermore, the elastic spacer 640 prevents adhesion between the tea leaves 10 and the forming mold 620, preventing the tea leaves 10 from sticking to the mold. This eliminates the need for mold cleaning, saving labor.

[0050] In some embodiments, the upper mold 600 further includes a counterweight 630, the opposite ends of which are fixedly connected to the template 610 and the upper mold 600. It is understood by those skilled in the art that after the tea leaves 10 in the accommodating cavity 310 are pressed, pressure maintenance is required to ensure that the pressed tea cake 20 has a good shape. Pressure maintenance requires continuous pressure on the upper mold 600. If an external force is used to drive the pressure maintenance, on the one hand, energy consumption increases, and on the other hand, it is not conducive to the coordinated use of multiple molds. Therefore, in the embodiment of the present application, the upper mold 600 is also provided with a counterweight 630. When pressure maintenance is required, the pressure can be maintained by the weight of the counterweight 630 itself, thus eliminating the need for additional power and saving energy. On the other hand, when multiple molds are used to produce the tea cake 20 in collaboration, the driving component only needs to drive the upper mold 600 until it closes with the lower mold 100 before driving another mold, without the need for additional power for pressure maintenance. In this way, the driving device can be saved and costs can be saved. It will be understood by those skilled in the art that, when multiple molds are reviewed collaboratively, the driving device can be set to have an automatic disassembly connection with the upper mold 600, and the automatic disassembly connection is a prior art in the field and will not be described in detail here.

[0051] In some embodiments, the mold further includes a retrieval claw 700 that can extend into the accommodating cavity 310 and is used to remove the pressed tea cake 20 from the accommodating cavity 310. Specifically, after the tea cake 20 is pressed and formed, the upper mold 600 is reset, the ejector mold 200 lifts the spacer 400, and pushes the tea cake 20 located on the spacer 400 into the accommodating cavity 310. As the inner diameter of the accommodating cavity 310 gradually increases, a gap appears between the tea cake 20 and the side wall of the accommodating cavity 310. The retrieval claw can extend into this gap to remove the tea cake 20 from the accommodating cavity 310. This avoids workers having to remove the tea cake 20 from the accommodating cavity 310, thereby improving production efficiency. It will be appreciated by those skilled in the art that the installation method of the retrieval claw 700 can adopt existing technology and will not be described in detail here.

[0052] In some embodiments, reference Figure 6 The bottom wall of the lower mold cavity 110 is further provided with a plurality of first vent holes, and / or the ejector mold 200 is provided with a plurality of first vent holes 201. The first vent holes 201 penetrate the bottom wall of the lower mold cavity 110 or the ejector mold 200 along the direction from the lower mold 100 to the upper mold 600. That is, the first vent holes 201 can be provided on both the bottom wall of the lower mold cavity 110 and the ejector mold 200, or can be provided only on the bottom wall of the lower mold cavity 110 or the ejector mold 200. Specifically, those skilled in the art can determine the first vent holes 201 based on the ratio of the upper surface of the ejector mold 200 to the bottom wall area of ​​the lower mold cavity 110. For example, if the upper surface of the ejector mold 200 accounts for more than four-fifths of the bottom wall area of ​​the lower mold cavity 110, the first vent holes 201 can be provided only on the ejector mold 200. The specific method of providing the first vent holes 201 is not specifically limited in the embodiments of this application. Furthermore, the isolating member 400 is also provided with a plurality of second ventilation holes 401, which are in communication with the first ventilation holes 201. It is understood that the diameter of the second ventilation holes 401 is relatively small, so that the tea leaves 10 in the accommodating cavity 310 and the debris generated during the pressing of the tea leaves 10 cannot pass through the second ventilation holes 401.

[0053] Those skilled in the art will appreciate that, during the process of pressing the tea leaves 10 using the upper mold 600, the air in the accommodating cavity 310 and the lower mold cavity 110 is compressed, which will increase the resistance of the upper mold 600, thereby increasing energy consumption, and bubbles are more likely to appear in the pressed tea cake 20. In the embodiment of the present application, by providing a second vent 401 on the spacer 400 and opening a first vent 201 on the bottom wall of the lower mold cavity 110 and / or the ejector 200, during the pressing process of the upper mold 600, the accommodating cavity 310 and the lower mold cavity 110 are connected to the outside world through the second vent 401 and the first vent 201, and the air in the accommodating cavity 310 and the lower mold cavity 110 can be discharged through the first vent 201 and the second vent 401, thereby reducing the resistance of the upper mold 600 during pressing and improving the quality of the tea cake 20.

[0054] This application also provides an embodiment of a pressed product, in which the pressed product is made using any of the molds described above. Since the pressed product is made using any of the molds described above, the pressed product at least has the technical effects brought about by the molds described above, and will not be further described here.

[0055] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its central idea.
