Description

Technical Field

[0001] This invention belongs to the field of Zisha (purple clay) technology, specifically relating to an energy-saving integrated molding equipment for Zisha sculpture and its production method. Background Technology

[0002] Zisha ware is a type of ceramic product that falls between pottery and porcelain. It is made from Zisha clay and fired, and is characterized by its natural color, translucency, good water content, excellent color, and delicate feel. It is a traditional handicraft that is very popular in China.

[0003] Traditional mechanical processing of Zisha clay sculptures mainly involves applying pressure to the clay in the mold to change its shape. This processing method is fast, but because the surface is not smoothed with a scraper, it is very rough, dull, and grainy, lacking the smoothness that Zisha should have. The sculptures are intricate and complex in structure, and the amount of work required to smooth them by hand after demolding is too great, affecting the production speed. If professional Zisha product surface treatment equipment (such as five-axis CNC polishing equipment) is used, it is not only laborious, costly, and inefficient for Zisha sculptures with complex surface shapes, but also consumes a lot of energy. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an energy-saving integrated molding equipment and production method for Zisha (purple clay) sculptures. The inner cavity of the elastic silicone mold continuously performs a flexible friction action on the surface of the Zisha clay, mimicking the manual smoothing of the clay surface with a scraper. This achieves the smoothness and finish of the Zisha clay surface after scraping and finishing, completing the entire process from clay preparation to molding and surface treatment in one step. Furthermore, it features low energy consumption, high processing speed, and superior surface treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving integrated molding equipment for Zisha sculpture, comprising an elastic silicone mold for extruding Zisha clay into Zisha sculpture pieces, wherein the top of the elastic silicone mold is provided with an inlet and outlet, and the bottom of the elastic silicone mold is fixedly connected with a vibration motor. The elastic silicone mold is suspended at multiple angles by several flexible wires to form a suspended state, and in the suspended state, the purple clay is extruded and shaped into a purple clay sculpture.

[0006] As a preferred embodiment of the energy-saving integrated molding equipment for Zisha sculpture of the present invention, a portion of the flexible wire is embedded inside the elastic silicone mold, wherein the end of the embedded portion of the flexible wire extends to a position corresponding to the recess of the Zisha sculpture.

[0007] As a preferred embodiment of the energy-saving integrated molding equipment for Zisha sculpture of the present invention, it further includes several hard molds, which are arranged around the outer side of the elastic silicone mold from different directions to squeeze the outer surface of the elastic silicone mold, thereby forcing the elastic silicone mold to further squeeze the Zisha clay inside.

[0008] As a preferred embodiment of the energy-saving integrated molding equipment for Zisha sculpture of the present invention, the exposed section of the flexible wire located outside the elastic silicone mold is fixed to the side of the rigid mold facing the elastic silicone mold. The flexible wire extending to the corresponding position of the recess of the Zisha sculpture is shorter than the other flexible wires, and the length of the flexible wire is negatively correlated with the depth of the corresponding recess of the Zisha sculpture, that is, the greater the depth of the recess, the shorter the length of the flexible wire at the corresponding position.

[0009] As a preferred embodiment of the energy-saving integrated molding equipment for Zisha sculpture of the present invention, each hard mold unit is connected to the outer shell of the device through a linear actuator. The linear actuator is fixed on the outer shell, and the direction of motion of the linear actuator is consistent with the mold opening direction of the corresponding hard mold unit, that is, it moves outward along the line connecting the center of the hard mold unit and the center of the Zisha sculpture.

[0010] As a preferred embodiment of the energy-saving integrated molding equipment for purple clay sculpture of the present invention, the hard mold unit corresponding to the position of the vibration motor is provided with a clamping part adapted to the vibration motor on its inner side. When the hard mold unit is closed, the clamping parts together form a clamping space.

[0011] As a preferred embodiment of the energy-saving integrated molding equipment for purple clay sculpture of the present invention, the vibration motor is provided with a mating groove for cooperating with the clamping part.

[0012] As a preferred embodiment of the energy-saving integrated molding equipment for Zisha clay sculpture of the present invention, each hard mold unit has a conical connecting piece fixedly connected to its outer surface. The end of the linear actuator pointing towards the hard mold is provided with a conical mating part that cooperates with the conical connecting piece. When multiple hard mold units are in a closed contact state from separation, the linear actuator and the corresponding hard mold unit are connected by a flexible connecting sleeve. When multiple hard mold units are in a closed pressure state, the conical connecting piece and the conical mating part are tightly fitted.

[0013] A method for producing Zisha (purple clay) sculptures includes the following steps: S1: Expand and open the elastic silicone mold; S2: Place the purple clay material into the elastic silicone mold; S3: Start the vibration motor; S4: When the vibration motor is working, the elastic silicone mold will elastically contract. S5: After the elastic silicone mold reaches its limit of elastic shrinkage, multiple rigid mold units move from different directions toward the surface of the elastic silicone mold, so that the rigid mold is pressed against the outer surface of the elastic silicone mold. S6: After the hard mold is used to compress the outer surface of the elastic silicone mold, several hard mold units are moved outward along the line connecting the center of the hard mold unit and the center of the purple clay sculpture. S7: After expanding and opening the elastic silicone mold again, take out the purple clay sculpture.

[0014] This invention provides a method for producing purple clay sculptures. In steps S1-S4, the elastic silicone mold operates in a suspended state formed by several flexible wires suspended at multiple angles; In step S5, the vibration motor remains running before the multiple hard mold units close and contact each other, including when the multiple hard mold units close and contact each other; the vibration motor stops working when the multiple hard mold units perform the closing pressure operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention abandons the traditional direct pressing molding processing method, but first stretches and expands the elastic silicone mold, puts the purple clay of a certain quality into the elastic silicone mold through the inlet and outlet, and then removes the force of stretching the elastic silicone mold, so that the elastic silicone mold shrinks through its own elasticity. With the cooperation of the vibration motor at the bottom of the elastic silicone mold, the continuous vibration of the vibration motor forces the cavity surface of the elastic silicone mold to continuously impact and squeeze the surface of the purple clay in a microscopic state. This is more conducive to changing the shape of the purple clay sculpture under the elastic shrinkage of the elastic silicone mold, so that the purple clay gradually approaches the inner cavity shape of the elastic silicone mold. During the elastic shrinkage of the elastic silicone mold, combined with microscopic vibration, the inner cavity surface of the elastic silicone mold continuously performs a soft friction action on the surface of the purple clay. This can mimic the action of a person manually smoothing the surface of the purple clay with a scraper, achieving the smoothness of the purple clay surface after scraping and trimming. This allows for a one-time completion of the process from clay preparation to shaping and surface treatment, with low energy consumption, fast processing speed, and better surface treatment.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-9 As shown: An energy-saving integrated molding equipment for Zisha sculpture includes an elastic silicone mold 2 for extruding Zisha clay into a Zisha sculpture 1. The top of the elastic silicone mold 2 is provided with an inlet / outlet 4, and the bottom of the elastic silicone mold 2 is fixedly connected with a vibration motor 3. The elastic silicone mold 2 is suspended at multiple angles by several flexible wires 6 to form a suspended state, and in the suspended state, the purple clay is extruded and shaped into a purple clay sculpture 1.

[0019] Traditional mechanical processing of Zisha clay sculpture models mainly involves applying pressure to the Zisha clay in the mold to change its shape. This processing method is fast, but because the surface is not smoothed by a scraper, it is very rough, dull, and grainy, lacking the smoothness that Zisha should have. The sculpture has a delicate shape and complex structure, and the amount of work required to smooth it by hand after demolding is too large, which affects the production speed. If professional Zisha product surface treatment equipment (such as five-axis CNC polishing equipment) is used, for Zisha sculptures with complex surface shapes, it is not only laborious, costly, and inefficient, but also consumes a lot of energy. This invention abandons the traditional direct pressing molding process. Instead, it first stretches and expands the elastic silicone mold 2, and then puts a certain amount of purple clay material into the elastic silicone mold 2 through the inlet and outlet 4. Then, the force of stretching the elastic silicone mold 2 is removed, allowing the elastic silicone mold 2 to shrink through its own elasticity. In conjunction with the vibration motor 3 at the bottom of the elastic silicone mold 2, the continuous vibration of the vibration motor 3 forces the cavity surface of the elastic silicone mold 2 to continuously impact and squeeze the surface of the purple clay material in a microscopic state. This is more conducive to changing the shape of the purple clay sculpture under the elastic shrinkage of the elastic silicone mold 2, so that the purple clay material gradually approaches the inner cavity shape of the elastic silicone mold 2. During the elastic shrinkage of the elastic silicone mold 2, combined with microscopic vibration, the inner cavity surface of the elastic silicone mold 2 continuously performs a soft friction action on the surface of the purple clay, which can imitate the human hand using a scraper to smooth the surface of the purple clay, achieving the smoothness of the purple clay surface after scraping and trimming, realizing the one-time completion from clay to processing and shaping to surface treatment, and with low processing energy consumption, fast processing speed, and better surface treatment. The reason why the surface of the Zisha sculpture 1 has a noticeable grainy texture due to traditional processing methods is not only because the surface of the Zisha sculpture 1 is not smoothed with a scraper. When the Zisha clay is squeezed into the mold, the clay will tear due to compression. After it fits into the mold cavity, it will be forcibly squeezed closed. This is also one of the main reasons for the poor surface texture of the Zisha sculpture 1. However, this solution does not cause the surface of the Zisha clay to tear during the plasticization process. The flexible elastic silicone mold 2 can mimic the flexible "pinching" of the Zisha clay surface from multiple angles when it contracts by its own elasticity. Therefore, the surface of the Zisha clay will not tear. This is also one of the important prerequisites for achieving the effect of "mimicking the smoothing of the Zisha clay surface by hand with a scraper".

[0020] In an optional embodiment, a portion of the flexible wire 6 is embedded inside the elastic silicone mold 2, wherein the embedded end of a portion of the flexible wire 6 extends to a position corresponding to the recess of the purple clay sculpture 1.

[0021] In this embodiment, as Figure 7As shown, the flexible wire 6, which is labeled, is embedded in the corresponding position of the recess of the Zisha sculpture 1. In this way, when demolding, that is, when the elastic silicone mold 2 is stretched and expanded by the flexible wire 6, the recess of the elastic silicone mold 2 can be pulled out, so as to avoid affecting the demolding of the Zisha sculpture 1.

[0022] In an optional embodiment, a plurality of rigid molds 5 are also included, which are arranged around the outer side of the elastic silicone mold 2 from different directions to squeeze the outer surface of the elastic silicone mold 2, thereby forcing the elastic silicone mold 2 to further squeeze the purple clay material inside.

[0023] In this embodiment, relying solely on the elasticity of the elastic silicone mold 2 and the vibration of the vibration motor 3, it is difficult to completely mold the purple clay into a purple clay sculpture 1. This step can only achieve the approximate shaping of the purple clay sculpture 1, and its details are not fully presented. Therefore, it is necessary to apply further pressure to the approximately shaped purple clay sculpture 1 in order to complete the shaping of the details of the purple clay sculpture 1. With the cooperation of the vibration of the vibration motor 3, after the elastic silicone mold 2 shrinks to its limit, multiple hard mold units 5 move towards the surface of the elastic silicone mold 2 from different directions, thereby achieving the effect of applying pressure by pressing the hard mold 5 onto the outer surface of the elastic silicone mold 2. It should be noted that when several hard mold units 5 are pressed together to compress the elastic silicone mold 2, the embedded section of the flexible wire 6 is wrapped inside the elastic silicone mold 2, and the exposed section is sandwiched between the elastic silicone mold 2 and the hard mold 5. Because the diameter of the flexible wire 6 is much smaller than the forming accuracy requirements of the Zisha sculpture 1, and the elastic silicone mold 2 has good elastic deformation capability, the extrusion pressure of the hard mold 5 will be evenly distributed through the flexible deformation of the elastic silicone mold 2, and the local pressure formed by the flexible wire 6 will not be concentrated on the surface of the Zisha clay. At the same time, the elastic silicone mold 2 will form a wrapping buffer for the flexible wire 6 to avoid hard contact between the wire and the Zisha clay. Therefore, the outline of the flexible wire 6 will not be imprinted on the surface of the Zisha sculpture 1.

[0024] In an optional embodiment, the exposed section of the flexible wire 6 outside the elastic silicone mold 2 is fixed to the side of the rigid mold 5 facing the elastic silicone mold 2. The flexible wire 6 extending to the corresponding position of the recess of the purple clay sculpture 1 is shorter than the other flexible wires 6, and the length of the flexible wire 6 is negatively correlated with the depth of the corresponding recess of the purple clay sculpture 1, that is, the greater the depth of the recess, the shorter the length of the flexible wire 6 at the corresponding position.

[0025] In this embodiment, the flexible wire 6 extending to the corresponding position of the recess in the purple clay sculpture 1 is shorter than the other flexible wires 6, and the length of the flexible wire 6 is negatively correlated with the depth of the corresponding recess in the purple clay sculpture 1. That is, the greater the depth of the recess, the shorter the length of the flexible wire 6 at the corresponding position. This can achieve the following when the rigid mold 5 is moved away from the elastic silicone mold 2 during demolding: the recess of the elastic silicone mold 2 is pulled away from the purple clay sculpture 1 first, which can avoid demolding interference and ensure the surface gloss of the purple clay sculpture 1.

[0026] In an optional embodiment, each hard mold 5 unit is connected to the device housing 9 via a linear actuator 8. The linear actuator 8 is fixed to the housing 9, and the direction of movement of the linear actuator 8 is consistent with the mold opening direction of the corresponding hard mold 5 unit, that is, it moves outward along the line connecting the center of the hard mold 5 unit and the center of the purple clay sculpture 1.

[0027] In this embodiment, the linear actuator 8 drives the hard mold 5 unit to move linearly. The linear actuator 8 can be a hydraulic rod or an electric lead screw to achieve synchronous separation of each hard mold 5 unit in the radial direction, so as to avoid damage to the purple clay sculpture 1 during demolding.

[0028] In an optional embodiment, the hard mold 5 unit corresponding to the position of the vibration motor 3 has a clamping part adapted to the vibration motor 3 on its inner side. When the hard mold 5 unit is closed, the clamping parts together form a clamping space.

[0029] In this embodiment, after the rigid mold 5 unit corresponding to the position of the vibration motor 3 is closed, the clamping space formed by its clamping part can fix the vibration motor 3 and drive the rigid mold 5 unit to vibrate synchronously. This can improve the transmission efficiency of vibration force, so that the vibration force is evenly transmitted to the entire outer surface of the elastic silicone mold 2 through the rigid mold 5 unit, avoiding uneven local vibration intensity caused by the loss of vibration force in the flexible silicone mold, and allowing all parts of the purple clay to obtain uniform vibration force. Secondly, when the rigid mold 5 unit vibrates synchronously with the vibration motor 3, it will form a rigid constraint on the elastic silicone mold 2, preventing the silicone mold from macroscopically shaking or shifting during vibration, ensuring the consistency of batch molding of products. Moreover, the vibration force and the rigid mold The synergistic effect of the five extrusion units enhances the plasticity and fluidity of the Zisha clay, allowing the clay to fill the fine cavities of the silicone mold more precisely, achieving clear shaping of complex structures. It also reduces the extrusion pressure requirements of the five units of the hard mold, preventing tearing of the clay due to excessive extrusion. Furthermore, the uniform vibration force allows the clay to fully expel internal air bubbles, increase its density, and reduce molding defects such as pinholes and shrinkage cavities. In addition, the uniform vibration allows for more flexible friction between the elastic silicone mold 2 and the clay surface (because the elastic silicone mold 2 itself can still vibrate under microscopic conditions even when held by the hard mold 5 and the Zisha sculpture 1), further enhancing the fineness and warm texture of the clay surface and improving the surface quality of the finished product.

[0030] In an optional embodiment, the vibration motor 3 is provided with a mating groove 7 for engaging with the clamping part.

[0031] In this embodiment, since the vibration motor 3 is located below the elastic silicone mold 2, when the elastic silicone mold 2 changes from an expanded state to a contracted state, the vibration motor 3 will move upward due to the elasticity of the elastic silicone mold 2. However, due to the weight of the vibration motor 3 itself, it is difficult to completely reset by relying solely on the elastic force of the elastic silicone mold 2. Therefore, a mating groove 7 is provided. The protrusion on the hard mold 5 unit corresponding to the position of the vibration motor 3 mates with the mating groove 7. When the hard mold 5 unit moves towards the elastic silicone mold 2 and gradually closes, the protrusion will first form a snap-fit ​​with the mating groove 7 before the clamping part. Under the continuous mold closing action of the hard mold 5 unit, the protrusion applies a pushing force to the vibration motor 3 through the groove wall of the mating groove 7. The pushing force and the weight of the vibration motor 3 form an opposite balance, realizing the smooth reset of the vibration motor 3 after further upward movement. After the protrusion and the mating groove 7 are fully engaged, the vibration motor 3 can be completely reset.

[0032] In an optional embodiment, each rigid mold unit 5 has a conical connector 10 fixedly connected to its outer surface. The end of the linear actuator 8 pointing towards the rigid mold 5 is provided with a conical mating part 11 that mates with the conical connector 10. When multiple rigid mold units 5 are in a closed contact state from separation, the linear actuator 8 and the corresponding rigid mold unit 5 are connected by a flexible connecting sleeve 12. When multiple rigid mold units 5 are in a closed pressure state, the conical connector 10 and the conical mating part 11 are tightly engaged.

[0033] In this embodiment, one end of the flexible connecting sleeve 12 can be fixedly connected to the conical mating part 11, and the other end of the flexible connecting sleeve 12 can be fixedly connected to the surface of the corresponding hard mold 5 unit. When multiple hard mold 5 units are in closed contact, the linear actuator 8 and the corresponding hard mold 5 unit are connected by the flexible connecting sleeve 12. At this time, the further extension of the linear actuator 8 should be paused, while the operation of the vibration motor 3 continues. The vibration of the vibration motor 3 will drive the hard mold 5 and the elastic silicone mold 2 to vibrate together. Through the flexible connecting sleeve 12, the excessive vibration can be avoided from being transmitted to the linear actuator 8, which would shorten the life of the linear actuator 8. After completing this step, the operation of the vibration motor 3 is paused, and the extension of the linear actuator 8 continues until multiple hard mold 5 units are in a closed pressure state. At this time, the conical connecting part 10 and the conical mating part 11 are tightly fitted, which further improves the fitting accuracy of the hard mold 5 after mold closing and improves the molding quality of the purple clay sculpture 1.

[0034] A method for producing Zisha (purple clay) sculptures includes the following steps: S1: Expand and open the elastic silicone mold 2; S2: Place the purple clay material into the elastic silicone mold 2; S3: Start vibration motor 3; S4: When the vibration motor 3 is working, the elastic silicone mold 2 is elastically contracted; S5: After the elastic silicone mold 2 reaches its limit of elastic contraction, multiple hard mold units 5 move from different directions toward the surface of the elastic silicone mold 2, so that the hard mold 5 is pressed against the outer surface of the elastic silicone mold 2. S6: After the hard mold 5 has finished extruding the outer surface of the elastic silicone mold 2, several hard mold 5 units are moved outward along the line connecting the center of the hard mold 5 unit and the center of the purple clay sculpture 1. S7: After expanding and opening the elastic silicone mold 2 again, take out the purple clay sculpture piece 1.

[0035] As a method for producing a purple clay sculpture according to the present invention, in steps S1-S4, the elastic silicone mold 2 works in a suspended state formed by multiple angles of several flexible wires 6. In step S5, before the multiple hard mold units 5 close and contact, including when the multiple hard mold units 5 close and contact, the vibration motor 3 remains in the started state; when the multiple hard mold units 5 perform the closing pressure operation, the vibration motor 3 stops working.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
