DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0027] An embodiment of the present application provides a mold, which 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 described using pressed teas such as tea cakes as an example. For other moon cakes, etc., please refer to the description of 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 housing 300 and an isolator 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 force on the tea cake 20 is balanced when the ejection mold 200 is ejected, and avoiding the tea cake 20 from being biased when being ejected.
[0030] Those skilled in the art can also understand that there can be multiple ejector molds 200. When there are multiple ejector molds 200, there are also 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 about the center point of the lower mold cavity 110. This is to ensure that the ejection force applied by the ejector mold 200 to the tea cake 20 is balanced during ejection, to ensure that the tea cake 20 can be ejected in a vertical direction, and to avoid collision between the tea cake 20 and the lower mold 100 or the shell 300 during the ejection process, thereby damaging 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 make 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 can be understood by those skilled in the art that the isolating member 400 can be a material that does not have elasticity, such as isolation paper and isolation cloth, or can be a material that has elasticity, such as a silicone pad. However, it should be noted that when the isolating member 400 is a material that does not have elasticity, such as isolation paper and isolation cloth, then 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 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 isolating member 400 is preferably made of an elastic material such as a silicone pad. The periphery of the isolating member 400 is fixed between the shell 300 and the lower mold 100. The isolating member 400 is elastic. Specifically, the isolating member 400 can be made of an elastic material such as rubber or 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 isolating member 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 buckles can be provided on the outer wall of the shell 300 for fixing 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 set 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 embodiment of the present application does not make specific restrictions. Specifically in the embodiment 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 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 there is no need to replace it 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, it will inevitably be damaged. 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 the ejector mold 200 is located below the isolation member 400, and the upper surface of the ejector mold 200 is flush with the bottom surface of the lower mold cavity 110. This arrangement can prevent the upper surface of the ejector mold 200 from affecting the molding of the tea cake 20. It can be understood by those skilled in the art that the upper surface of the ejector mold 200 is flush with the bottom surface of the lower mold cavity 110, and it should be understood that the upper surface of the ejector mold 200 and the bottom surface of the lower mold cavity 110 together constitute the bottom surface shape of the tea cake 20.
[0037] The ejector mold 200 can move along the axial direction of the mounting hole 120, and at least partially extend into the lower mold cavity 110, and the ejector mold 200 can drive the isolation member 400 to deform. It can be understood that the ejector mold 200 ejects the tea cake 20 located in the lower mold cavity 110 during the demolding process, 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 piece 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 piece 400 to move upward. Since the isolating piece 400 is elastic, the isolating piece 400 will not be damaged during this process, and the isolating piece 400 will be deformed, that is, the isolating piece 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 manufactured 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 isolating member 400, the tea leaves 10 will not fall onto the wall surface of the lower mold cavity 110. Since the isolating member 400 is elastic, during the pressing process, the isolating member 400 will deform as the pressure increases, and therefore will not hinder the pressing and forming of the tea cake 20. When the tea leaves 10 are pressed into the tea cake 20, at this time, the isolating member 400 is located between the bottom of the tea cake 20 and the bottom wall of the lower mold cavity 110, and then the tea cake 20 located above the isolating member 400 is lifted by the ejection mold 200, and the tea cake 20 is ejected from the lower mold cavity 110. Since the tea leaves 10 are isolated from the wall of the lower mold cavity 110 by the isolation member 400 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 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 isolating member 400 is partially adhered to the upper surface of the ejector mold 200. It can be understood by those skilled in the art that the isolating 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 isolating member 400 is adhered to the upper surface of the ejector mold 200 by adhesive, and then the periphery of the isolating member 400 is fixed to the lower mold 100, and finally the ejector mold 200 is reset. Since the isolating member 400 is elastic, the isolating member 400 can be deformed during the reset of the ejector mold 200, thereby preventing the isolating 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, which can ensure that the central area of the spacer 400 is flat, thereby ensuring that the spacer 400 is as flat as possible as a whole, and avoiding changes in the bottom structure of the tea cake 20 due to the wrinkles of the spacer 400. It can also be understood by those skilled in the art 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 reach more than half of the bottom surface area of the lower mold cavity 110, so that the area of the spacer 400 bonded to the ejection mold 200 can be increased, thereby avoiding uneven deformation of the spacer 400 and wrinkles, resulting in irregular bottom of the tea cake 20, increasing the forming state of the tea cake 20, and improving the forming quality of the tea cake 20.
[0040] In some embodiments, the mounting hole 120 is a stepped hole, and 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 the embodiment of the present application, the stepped hole can support the ejector mold 200, so that during the pressing process of the tea leaves 10, the ejector mold 200 does not need to provide additional support force, and the stepped surface of the stepped hole can be used. And by supporting the ejector mold 200 on the stepped surface, it can also ensure that the upper surface of the ejector mold 200 is 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 ejector portion 210 and a connecting portion 220 that are fixedly connected. The diameter of the ejector portion 210 is larger than the diameter of the connecting portion 220. The upper surface of the ejector 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 ejector 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 opposite ends of the spring plunger 500 are respectively abutted against the bottom wall surface of the blind hole and the peripheral wall surface of the second hole.
[0042] Specifically, the spring plunger 500 includes a spring and a push rod, the two ends of the spring are respectively fixedly connected to the push rod and the bottom wall of the blind hole, the end of the push rod away from the spring is a spherical head, and when the push rod is located in the second hole, the spring is in a compressed state, so the push rod is pressed against the peripheral wall surface of the second hole, so that the ejector mold 200 can be prevented from shaking in the mounting hole 120. It can be understood that a chamfer is also provided at the connection between the first hole and the second hole, so as to facilitate the push rod to slide from the first hole into the second hole.
[0043] Those skilled in the art can also understand that there can be multiple spring plungers 500, and the multiple spring plungers 500 are evenly distributed along the circumference of the connecting portion 220, and the multiple spring plungers 500 are on the same circumferential surface. Such an arrangement can ensure that the ejector mold 200 is subjected to a balanced force. By providing multiple spring plungers 500, it can be further ensured that the ejector mold 200 can be stably located in the step hole.
[0044] Please refer to Figure 7 In some other embodiments, the mounting hole 120 is a conical surface, and the ejector mold 200 is provided with a conical surface corresponding to the conical surface. In the embodiment of the present application, the conical surface on the mounting hole 120 cooperates with the conical surface of the ejector mold 200, so that the lower mold 100 can carry the ejector mold 200. And setting the mounting hole 120 as a conical surface is convenient for positioning the ejector mold 200. The conical surface 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 after each ejection of 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 the embodiment of the present application, due to the presence of the isolator 400, in order to avoid permanent deformation of the isolator 400 and increase the service life of the isolator 400, the deformation of the isolator 400 should not be too large. In the embodiment of the present application, in order to ensure that the tea leaves 10 in the accommodating cavity 310 are sufficient to press the tea cake 20, the height of the accommodating cavity 310 is generally high. The specific height can be set by those skilled in the art according to the specific weight and shape of the tea cake 20. After the tea cake 20 is formed, due to the limitation of the deformation of the isolator 400, the ejection mold 200 should not be ejected too high. Therefore, the ejection mold 200 cannot eject the tea cake 20 from the upper opening of the top of the accommodating cavity 310. In the embodiment of the present application, since the isolator 400 is located between the shell 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 isolator 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 so that the inner diameter gradually increases from the lower opening to the upper opening. That is to say, 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 isolation member 400, thereby extending the service life of the isolation member 400.
[0046] In some embodiments, the mold further includes an upper mold 600, which is located above the lower mold 100, and the upper mold 600 can pass through the accommodating cavity 310 and close with the lower mold 100. In the embodiment of the present application, the tea leaves 10 in the accommodating cavity 310 are pressed by the upper mold 600 and finally formed. During the pressing process, due to the presence of the isolation member 400, it can be prevented that the tea leaves 10 debris caused by pressing contact the wall surface 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 molding mold 620, the molding mold 620 is fixedly connected to the side of the template 610 facing the lower mold 100, and the side of the molding mold 620 facing the lower mold 100 is provided with a molding cavity 621. It can be understood by those skilled in the art that the molding cavity 621 is designed according to the shape of the tea cake 20. For example, if the tea cake 20 is square, the molding cavity 621 can be a plane; for another example, if the tea cake 20 is convex on one side, the molding cavity 621 can be set to a corresponding groove. In the embodiment of the present application, since the upper part of the tea cake 20 is an arc-shaped protrusion, the molding cavity 621 is set to an arc-shaped groove.
[0048] Those skilled in the art can 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, the side of the molding die 620 facing the lower die 100 is provided with an elastic spacer 640. It can be understood by those skilled in the art that the elastic spacer 640 can be a silicone pad, and the silicone pad is used to cover the side of the molding die 620 facing the lower die. Specifically, it can be fixed by an adhesive or the like, or it can be fixed by setting a card slot or the like on the peripheral wall of the molding die 620. The embodiment of the present application does not make specific restrictions, but it should be noted that the elastic spacer 640 should be close to the side of the molding die 620 facing the lower die 100 to ensure that the surface of the pressed tea is intact during molding. In the embodiment of the present application, when the molding die 620 is molding the tea leaves 10 in the accommodating cavity 310, the elastic spacer 640 contacts the tea leaves 10, and the elastic spacer 640 has elasticity, so the pressed tea is closer to the artificial tea cake and has higher quality. In addition, the elastic spacer 640 can also prevent the tea leaves 10 from bonding with the molding die 620, and prevent the tea leaves 10 from sticking to the mold. In this way, there is no need to clean the mold, saving manpower.
[0050] In some embodiments, the upper mold 600 further includes a counterweight 630, and the two opposite ends of the counterweight 630 are respectively fixedly connected to the template 610 and the upper mold 600. It can be understood by those skilled in the art that after the tea leaves 10 in the accommodating cavity 310 are pressed, the pressed tea cake 20 needs to be in a better shape, and pressure maintenance is required. And 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 is increased, 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, pressure maintenance can be performed by the weight of the counterweight 630 itself, so that no additional power is required, saving energy. On the other hand, when multiple molds are used to produce tea cakes 20 in collaboration, the driving component only needs to drive the upper mold 600 to close with the lower mold 100, and then drive another mold without providing additional pressure maintenance power. In this way, the driving device can be saved and the cost 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 detachable connection with the upper mold 600, and the automatic detachable connection is a prior art in the art and will not be described in detail here.
[0051] In some embodiments, the mold further includes a taking-up gripper 700, which can be inserted into the accommodating cavity 310, and the taking-up gripper 700 is used to take out 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, and the ejection mold 200 lifts the isolation member 400 and pushes the tea cake 20 located on the isolation member 400 into the accommodating cavity 310. Since the inner diameter of the accommodating cavity 310 gradually increases, a gap will appear between the tea cake 20 and the side wall of the accommodating cavity 310, and the taking-up gripper can be inserted into the gap to take out the tea cake 20 from the accommodating cavity 310. In this way, it is possible to avoid workers taking out the tea cake 20 in the accommodating cavity 310, thereby improving production efficiency. It can be understood by those skilled in the art that the installation method of the taking-up gripper 700 can adopt the existing technology, which will not be repeated here.
[0052] In some embodiments, reference Figure 6 , the bottom wall of the lower mold cavity 110 is provided with a plurality of first vent holes, and / or the ejector mold 200 is provided with a plurality of first vent holes 201, and 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 only on the bottom wall of the lower mold cavity 110 or the ejector mold 200. Specifically, those skilled in the art can determine it according to 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. How the first vent holes 201 are provided is not specifically limited in the embodiments of the present application. Furthermore, the isolating member 400 is also provided with a plurality of second vent holes 401, which are connected to the first vent holes 201. It is understood that the diameter of the second vent holes 401 is relatively small, and 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 vent holes 401.
[0053] Those skilled in the art can understand that, during the process of pressing the tea leaves 10 by 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 likely to appear in the pressed tea cake 20. In the embodiment of the present application, by providing the second vent 401 on the isolating member 400, and opening the 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 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 pressing, and improving the quality of the tea cake 20.
