Description

Technical Field

[0001] This utility model relates to the technical field of ceramic product manufacturing equipment, and specifically discloses a mold for producing ceramic flower pots. Background Technology

[0002] Ceramic flowerpot production widely employs mold pressing molding technology, and the rationality of the mold structure directly affects product quality and production efficiency. Existing technologies already include several improvement schemes for ceramic flowerpot molds.

[0003] For example, a Chinese utility model patent (authorization announcement number: CN211137553U) discloses a mold for producing ceramic flower pots, which mainly includes a positioning device, a base, and a detachable outer mold and inner mold. This solution solves the misalignment problem when the inner and outer molds are closed by the cooperation of the fixing rod, limiting hole, and positioning bolt in the positioning device; by designing the outer mold as a combination of half-mold A and half-mold B connected by fixing screws, it facilitates the removal of the product from the mold during demolding; furthermore, a heating device and heat-conducting block are installed inside the base to solve the problem of rapid drying after mold cleaning.

[0004] However, the aforementioned existing technologies mainly focus on the static positioning of the mold, manual demolding, and post-construction maintenance; they do not provide solutions to the technical problems arising in the dynamic process of pressing ceramic blanks into shape within the mold. Furthermore, in actual production, the lifting mechanism driving the punch exerts a huge impact force on the mold at the moment of mold closing, which can easily lead to loosening of the guide mechanism, mold damage, and severe noise over time. In addition, the demolding of molded products mostly relies on manual operation or external equipment, making it difficult to achieve automated continuous production.

[0005] Therefore, there is an urgent need for a new type of mold for the production of ceramic flower pots that can effectively buffer the impact of mold closing, protect the equipment, and realize the automatic ejection of products, so as to adapt to modern automated production lines and improve production efficiency and stability. Utility Model Content

[0006] This utility model proposes a mold for producing ceramic flower pots. The mold effectively absorbs the impact force of mold closing through a guiding and buffering mechanism, reduces equipment noise and extends mold life. At the same time, the ejection mechanism enables automatic demolding of products, which significantly improves production efficiency and automation level, and ensures product molding quality.

[0007] This utility model is implemented as follows: a mold for producing ceramic flower pots includes a base, a concave mold disposed on the base, and a convex mold that cooperates with the concave mold. The bottom of the cavity of the concave mold is provided with an ejection hole; it also includes an ejection mechanism and a guide buffer mechanism. The ejection mechanism includes an ejector plate movably disposed in the ejection hole and a first drive member fixedly installed below the base. The power output end of the first drive member is connected to the ejector plate and is used to eject the molded flowerpot product from the cavity mold. The guiding and buffering mechanism includes at least two guide rods fixed to the base, a lifting plate slidably sleeved on the guide rods and fixedly connected to the punch, a top plate fixed to the top of the guide rods, a second driving component installed on the top plate for driving the lifting plate, and a shock-absorbing component sleeved on the guide rods; the shock-absorbing component is located between the lifting plate and the base and is used to buffer the impact generated when the punch is pressed down into place.

[0008] As a preferred embodiment of the mold for producing ceramic flowerpots according to this utility model, the shock-absorbing component includes a lower limiting ring fixedly sleeved on the guide rod, a sliding sleeve slidably sleeved on the guide rod, and a shock-absorbing spring sleeved on the guide rod; the two ends of the shock-absorbing spring respectively abut against the lower limiting ring and the sliding sleeve; when the lifting plate moves downward, it presses against the sliding sleeve and compresses the shock-absorbing spring.

[0009] As a preferred embodiment of the mold for producing ceramic flower pots according to this utility model, the top of the sliding sleeve is provided with an elastic buffer pad.

[0010] As a preferred embodiment of the mold for producing ceramic flower pots according to this utility model, the contact surface between the lifting plate and the guide rod is provided with a wear-resistant sleeve.

[0011] As a preferred embodiment of the mold for producing ceramic flowerpots according to this utility model, the first driving component and the second driving component are both servo electric cylinders, hydraulic cylinders or pneumatic cylinders.

[0012] As a preferred embodiment of the mold for producing ceramic flowerpots according to this utility model, the concave mold is composed of a left half mold and a right half mold joined together, and the left half mold and the right half mold are detachably fixed to the base by a locking mechanism.

[0013] As a preferred embodiment of the mold for producing ceramic flower pots according to this utility model, a guide sleeve is further provided between the top plate and the lifting plate. The guide sleeve is fixed on the lifting plate and slidably sleeved on the outside of the guide rod.

[0014] The beneficial effects of this utility model are: 1. The guide buffer mechanism effectively absorbs the impact of mold closing through the double buffering of shock-absorbing springs and elastic buffer pads, reducing equipment vibration and noise, preventing loosening of the guide mechanism and damage to the mold, and extending the service life of the equipment; in addition, the cooperation between the guide rod and the guide sleeve improves the accuracy of punch lifting, avoids mold closing misalignment, reduces product scrap rate and mold maintenance costs, and ensures stable production process.

[0015] 2. The ejection mechanism enables automatic demolding of products, replacing manual operation or external equipment, reducing human intervention and shortening demolding time; the split-type cavity mold and automatic ejection work together to further improve demolding efficiency, adapt to modern automatic production lines, and meet the needs of continuous production; the drive components can be selected from servo electric cylinders, hydraulic cylinders, and pneumatic cylinders, and the power parameters can be flexibly adjusted according to the production capacity to adapt to the production of flower pots of different specifications and improve the versatility of the equipment.

[0016] 3. Precise guiding and positioning of the mold closing pressure control ensures the shape and size accuracy of the flower pot products and avoids product deformation caused by mold misalignment or uneven pressure; the cavity mold locking mechanism ensures mold sealing, prevents blank overflow, improves the surface smoothness and molding integrity of the products, and the split cavity mold can be quickly disassembled and assembled through the locking mechanism, simplifying the mold maintenance and cleaning process.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-3A mold for producing ceramic flower pots includes a base 1, a concave mold 2 disposed on the base 1, and a convex mold 3 that cooperates with the concave mold 2. The bottom of the cavity of the concave mold 2 is provided with an ejection hole 4. It also includes an ejection mechanism and a guide buffer mechanism. The ejection mechanism includes an ejector plate 5 movably disposed in the ejection hole 4 and a first drive member 6 fixedly installed below the base 1. The power output end of the first drive member 6 is connected to the ejector plate 5 and is used to eject the molded flower pot product from the cavity mold 2. The guide buffer mechanism includes at least two guide rods 7 fixed on the base 1, a lifting plate 8 slidably sleeved on the guide rods 7 and fixedly connected to the punch 3, a top plate 9 fixed to the top of the guide rods 7, a second driving component 10 installed on the top plate 9 for driving the lifting plate 8, and a shock-absorbing component 11 sleeved on the guide rods 7; the shock-absorbing component 11 is located between the lifting plate 8 and the base 1 and is used to buffer the impact generated when the punch 3 is pressed down into place.

[0024] In this embodiment: the ceramic blank is placed into the cavity of the concave mold 2, which is formed by the left half mold 17 and the right half mold 18; the second driving component 10 is activated, driving the lifting plate 8 to move downward along the guide rod 7 fixed on the base 1, which in turn drives the punch 3 fixed to the lifting plate 8 to move downward and press the blank into shape; during this process, the guide sleeve 19 fixed on the lifting plate 8 slides along the guide rod 7 to ensure the mold closing accuracy; when the punch 3 is about to be pressed into place, the lifting plate 8 contacts and presses against the sliding sleeve 13 of the shock absorption component 11, and the sliding sleeve 13 slides downward and compresses the shock absorption spring 14 sleeved on the guide rod 7. At the same time, the elastic buffer pad 15 at the top of the sliding sleeve 13 further absorbs high-frequency vibration, thereby mitigating the impact through the elastic deformation of the spring. The damping effect of the punch pad converts the huge impact force of mold closing into elastic potential energy and releases it slowly, effectively buffering vibration, reducing noise, and protecting the mold and drive components from damage. The wear-resistant sleeve 16 and the lower limit ring 12 sleeved on the guide rod 7 together constrain the stroke of the sliding sleeve 13 to prevent overload. After molding, the second drive component 10 drives the punch 3 to rise and reset. Then, the ejection mechanism is activated, and the first drive component 6 fixed below the base 1 pushes the ejector plate 5, which is movably set in the ejection hole 4 at the bottom of the die 2, to move upward, smoothly and automatically ejecting the molded flower pot product that is close to the die 2, completing the demolding. Finally, the product is removed, and the first drive component 6 drives the ejector plate 5 to fall and reset, ready to enter the next production cycle.

[0025] As a technical optimization of this utility model, the shock absorption component 11 includes a lower limit ring 12 fixedly sleeved on the guide rod 7, a sliding sleeve 13 slidably sleeved on the guide rod 7, and a shock absorption spring 14 sleeved on the guide rod 7; the two ends of the shock absorption spring 14 abut against the lower limit ring 12 and the sliding sleeve 13 respectively; when the lifting plate 8 moves downward, it presses against the sliding sleeve 13 and compresses the shock absorption spring 14.

[0026] In this embodiment, the shock-absorbing component 11 consists of a lower limit ring 12, a sliding sleeve 13, and a shock-absorbing spring 14. The shock-absorbing component 11 avoids production errors caused by the ambiguity of the structure of the shock-absorbing component 11, while ensuring that the buffering effect is stable and controllable, thus enhancing the practicality of the patented technology.

[0027] As a technical optimization of this utility model, an elastic buffer pad 15 is embedded on the top of the sliding sleeve 13.

[0028] In this embodiment: based on the damping spring 14, flexible buffering is added when there is rigid contact, which further reduces impact noise and component wear, improves the stability and durability of equipment operation, and optimizes the details of the technical solution.

[0029] As a technical optimization of this utility model, a wear-resistant sleeve 16 is provided on the contact surface between the lifting plate 8 and the guide rod 7.

[0030] In this embodiment, the wear resistance of the lifting plate 8 is improved by using the wear-resistant sleeve 16.

[0031] As a technical optimization of this utility model, the first driving component 6 and the second driving component 10 are both servo electric cylinders, hydraulic cylinders or pneumatic cylinders.

[0032] In this embodiment, a variety of power options are provided for mold production, which can be flexibly adapted to actual production scenarios (such as capacity requirements, cost budgets, and workshop power conditions), thereby enhancing the applicability and scalability of the technical solution.

[0033] As a technical optimization of this utility model, the concave mold 2 is composed of a left half mold 17 and a right half mold 18 joined together, and the left half mold 17 and the right half mold 18 are detachably fixed to the base 1 by a locking mechanism 20.

[0034] In this embodiment: the problem of difficult demolding of the integral cavity mold 2 is solved. The split structure facilitates the removal of the molded product. At the same time, the locking mechanism 20 ensures the sealing when the mold is closed, avoids the blank overflow, and improves the product molding accuracy and demolding efficiency.

[0035] As a technical optimization of this utility model, a guide sleeve 19 is also provided between the top plate 9 and the lifting plate 8. The guide sleeve 19 is fixed on the lifting plate 8 and can be slidably sleeved on the guide rod 7.

[0036] In this embodiment: the guide sleeve 19 reduces the direct friction between the lifting plate 8 and the guide rod 7, reduces component wear, and improves the guiding accuracy of the sliding of the lifting plate 8, ensuring the positional accuracy of the punch 3 when it closes the mold, and further optimizing the stability of the equipment operation.

[0037] Working principle and usage process of this utility model: The left half mold 17 and the right half mold 18 are aligned and fixed to the base 1 by the locking mechanism 20. The ceramic blank is evenly placed into the cavity of the concave mold 2, ensuring that the blank covers the bottom of the cavity and has a uniform thickness. The second driving component 10 drives the lifting plate 8 to descend along the guide rod 7, moving the punch 3 closer to the concave mold 2. When the punch 3 approaches the concave mold 2, the lifting plate 8 presses against the sliding sleeve 13, and the sliding sleeve 13 compresses the shock-absorbing spring 14. The elastic buffer pad 15 and the shock-absorbing spring 14 work together to absorb the impact, and the punch 3 smoothly enters the cavity of the concave mold 2, applying pressure to the blank and making the blank fit the cavity to form the shape. The mold closing pressure is maintained. After the preset time, ensure that the ceramic blank is completely shaped into a flowerpot. After the pressure holding is completed, the second drive component 10 drives the lifting plate 8 to move upward, causing the punch 3 to disengage from the die 2 and return to the initial height. If the product is too tightly attached to the die 2, loosen the locking mechanism 20, separate the left half mold 17 and the right half mold 18, and assist in demolding. The first drive component 6 drives the ejector plate 5 to move upward along the ejection hole 4, ejecting the formed flowerpot product from the cavity of the die 2. The ejected product is removed manually or by automated equipment, and the first drive component 6 drives the ejector plate 5 to return to the bottom of the ejection hole 4, ready for the next production cycle.
