Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, specifically to a demolding machine for ceramic slip casting equipment. Background Technology

[0002] In the ceramics industry, the production of daily-use ceramics mostly employs slip casting. Slip casting is relatively simple: slurry made from the raw material is poured into a plaster mold. Because plaster molds are absorbent, the water in the slurry near the inner wall of the mold is absorbed by the porous plaster, forming a layer of clay on the inner wall of the mold with the same shape as the mold's inner wall. This clay layer thickens over time. After a period of time, the excess slurry is poured off, while the clay layer near the inner wall of the plaster mold remains inside. After another period of time, the clay layer naturally shrinks and detaches from the mold, allowing the rough blank to be removed.

[0003] In existing technologies, some ceramic slip casting production lines require manual loosening of clamps to demold the mold. This production method is not only time-consuming and labor-intensive, but also inefficient and not conducive to automated production. Summary of the Invention

[0004] The purpose of this utility model is to provide a demolding machine for ceramic slip casting equipment, which aims to solve the problem that the existing technology requires manual loosening of clamps to demold the mold, resulting in time-consuming, labor-intensive, and inefficient processes.

[0005] To achieve the above objectives, this utility model provides a demolding machine for a ceramic slip casting equipment, comprising: a frame, on which a mold-removing platform is provided for a clamping fixture to hold the mold; the clamping fixture includes a base plate, two columns, and a clamping mechanism, the two columns being vertically spaced apart on the base plate and positioned near one edge of the base plate; the clamping mechanism being slidably connected to the two columns for pressing the mold onto the base plate; the clamping mechanism having a protruding locking piece for releasing and locking the clamping mechanism from sliding on the two columns; a limiting hook disposed on the mold-removing platform for restricting the vertical movement of the base plate; and a clamp release device, movably mounted on the top of the frame and located above the mold-removing platform. The device is used to actuate the locking plate and cause the clamping mechanism to slide upward along the two columns to release the clamped mold.

[0006] Furthermore, the clamp release device includes a lifting mechanism, a fixed mounting plate, and a locking plate pulling mechanism. The lifting mechanism is vertically arranged at the top of the frame, and the fixed mounting plate is vertically connected to the bottom of the lifting mechanism. The bottom of the fixed mounting plate is provided with a pressure sleeve concentrically arranged with the column for pressing against the upper end face of the pressing mechanism. The pressure sleeve is provided with a positioning hole penetrating the fixed mounting plate, and the fixed mounting plate is provided with a stroke limit hole. The locking plate pulling mechanism includes a telescopic pull plate and a pull plate cylinder arranged on the fixed mounting plate. The upper end of the telescopic pull plate is slidably connected in the stroke limit hole, and the piston rod end of the pull plate cylinder is connected to the upper end of the telescopic pull plate. The lower end of the telescopic pull plate is vertically provided with a top plate for actuating the locking plate.

[0007] Furthermore, the base plate is provided with a top plate for actuating the locking plate.

[0008] Furthermore, the lifting mechanism includes a housing mounting base, a lifting column, and a column drive motor. The housing mounting base is fixedly mounted on the top of the frame via a mounting beam. The lifting column is vertically inserted inside the housing mounting base via a guide rail slider. The column drive motor is connected to a rack and pinion mounted on the lifting column via gears.

[0009] Furthermore, the fixed mounting plate is provided with a piston rod end that extends and retracts downward toward the fixed mounting plate, which is used to press against the upper end face of the pressing mechanism.

[0010] Furthermore, the clamping mechanism includes two movable sleeves, a pressure arm, a locking plate, and a spring; the two movable sleeves are slidably fitted onto two columns, and each movable sleeve has a cavity with an open end. A connecting plate is provided between the bottoms of the two movable sleeves. One end of the pressure arm is slidably fitted onto the column and fixedly connected to the upper end of the movable sleeve; the locking plate is slidably fitted onto the column and located inside the cavity of the movable sleeve, with one end of the locking plate extending outside the cavity for contacting the base plate; the spring is slidably fitted onto the column, with its upper end abutting against the inner top of the cavity and its lower end below the upper end of the locking plate.

[0011] Furthermore, the locking plate pulling mechanism is provided with at least two sets on the fixed mounting plate. At least two sets of clamp release devices are provided on the top of the frame.

[0012] Furthermore, the mold-taking platform is equipped with a conveying device for feeding and unloading the clamps holding the mold.

[0013] Furthermore, the conveying device includes a roller mounting base, a transmission roller, and a conveying motor. The roller mounting base consists of two spaced-apart side plates, and multiple fixed shafts spaced along their length are connected between the side plates. The transmission roller is rolled and sleeved on the fixed shafts, and one end of the transmission roller is provided with a roller sprocket. The conveying motor is located at the bottom of the mold-taking platform, and the output shaft end of the conveying motor is connected to each of the transmission rollers via chain drive.

[0014] The demolding machine of the ceramic slip casting equipment provided by this utility model, compared with the prior art, has a clamp holding the mold that enters from the mold removal platform. The clamp is equipped with a clamping mechanism for pressing the mold. The clamping mechanism is equipped with locking plates for releasing and locking the clamping mechanism from sliding on the two columns. The locking plates are moved by the clamp release device that can be raised and lowered at the top of the frame, which drives the clamping mechanism to slide upward along the two columns to release the clamped mold. The locking plates can be moved automatically and the clamping mechanism can release the clamping state of the mold without manual intervention, replacing the tedious operation of manually releasing the clamp, greatly reducing labor intensity and improving production efficiency.

[0015] In addition, by utilizing the lever-type force characteristics of the clamp's own locking plate, the clamp release device only needs to simply push the locking plate upward to trigger the clamping mechanism to slide upward on the column, releasing the clamping state on the mold. This eliminates the need for a complex power transmission structure, resulting in a simple structure, low failure rate, and reduced maintenance costs. Attached Figure Description

[0020] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] As shown in Figures 1 to 4, a demolding machine for a ceramic slip casting equipment includes a frame 10, a clamp 30, a limiting hook 21, and a clamp release device 40.

[0022] The frame 10 is a frame structure, and the frame 10 is equipped with a mold removal platform 20, into which the clamp 30 for holding the mold 1 enters.

[0023] The clamp 30 includes a base plate 31, two columns 32 and a clamping mechanism. The two columns 32 are vertically spaced on the base plate 31 and are located near one edge of the base plate 31. The clamping mechanism is slidably connected to the two columns 32 and is used to clamp the mold 1 onto the base plate 31. The clamping mechanism is provided with a protruding locking piece 35 for releasing and locking the clamping mechanism from sliding on the two columns 32.

[0024] The limiting hook 21 is set on the mold-taking platform 20 to limit the vertical movement of the base plate 31. The clamp release device 40 is vertically mounted on the top of the frame 10 and located above the mold removal platform 20. The clamp release device 40 is used to actuate the locking plate 35 and drive the clamping mechanism to slide upward along the two columns 32 to release the clamped mold 1.

[0025] In practice, after the clamp 30 holding the mold 1 enters the mold removal platform 20, the bottom plate 31 of the clamp 30 is locked by the limiting hook 21, specifically located at the edge of the bottom plate 31, which restricts the movement of the clamp 30 in the vertical direction. Then, the clamp release device 40 moves the locking plate 35 up and down and drives the clamping mechanism to slide upward along the two columns 32 to release the clamped mold 1, so that the mold 1 after grouting can be taken out.

[0026] Specifically, the clamping mechanism includes two movable sleeves 33, a pressure arm 34, a locking plate 35, and a spring 37. The two movable sleeves 33 are slidably fitted onto two columns 32. Each movable sleeve 33 has an internal cavity 331 with an opening at one end. A connecting plate 38 is provided between the bottoms of the two movable sleeves 33. One end of the pressure arm 34 is slidably fitted onto the column 32 and fixedly connected to the upper end of the movable sleeve 33. The locking plate 35 is slidably fitted onto the column 32 and located within the cavity 331 inside the movable sleeve 33. One end of the locking plate 35 extends outside the cavity 331 and is used by the clamp release device 40 to release the pressure arm 34 from sliding on the column 32. Spring 37 is slidably sleeved on post 32, with the upper end of spring 37 abutting against the inner top of cavity 331 and the lower end of spring 37 being lower than the upper end of locking piece 35.

[0027] In practical implementation, the clamping mechanism forms a self-locking structure with the movable sleeve 33, the locking plate 35, and the spring 37 (the locking plate 35 generates friction with the column 32 due to the pre-tightening force of the spring 37), realizing the single-action operation locking of the clamp 30. Simply pull up the locking plate 35 to compress the spring 37 to release the friction lock on the column 32, causing the pressure arm 34 on the movable sleeve 33 to rise and fall freely. After releasing the locking plate 35, the spring 37 automatically resets, allowing the movable sleeve 33 to be rigidly fixed on the column 32. This enables quick clamping of the ceramic forming mold 1, with a simple and reliable structure, low maintenance cost, and effectively improved clamping efficiency.

[0028] As shown in Figure 1 to Figure 6 As shown, in this embodiment, the clamp release device 40 includes a lifting mechanism 41, a fixed mounting plate 42, and a locking plate pulling mechanism 43. The lifting mechanism 41 is vertically arranged on the top of the frame 10, and the fixed mounting plate 42 is vertically connected to the bottom of the lifting mechanism 41.

[0029] The bottom of the mounting plate 42 is provided with a pressure sleeve 421 concentrically arranged with the column 32 for pressing against the upper end face of the clamping mechanism. The pressure sleeve 421 has a positioning hole 422 penetrating the mounting plate 42 for fixing. The mounting plate 42 is provided with a travel limit hole 423; The locking plate pulling mechanism 43 includes a telescopic pull plate 431 and a pull plate cylinder 432 disposed on the fixed mounting plate 42. The upper end of the telescopic pull plate 431 is slidably connected in the stroke limiting hole 423. The piston rod end of the pull plate cylinder 432 is connected to the upper end of the telescopic pull plate 431. The lower end of the telescopic pull plate 431 is vertically provided with a top plate 433 for actuating the locking plate 35.

[0030] In practice, the lifting mechanism 41 drives the locking plate pulling mechanism 43 on the fixed mounting plate 42 to perform lifting and lowering movements, and the plate cylinder 432 drives the telescopic plate 431 to perform forward and backward telescopic movements within the stroke limit hole 423. When it is necessary to release the clamp 30, the lifting mechanism 41 drives the fixed mounting plate 42 to move downward. The pressure sleeve 421 on the fixed mounting plate 42 then engages with the column 32 for positioning and finally descends to press against the upper end face of the movable sleeve 33. At this time, the telescopic pull plate 431 has a certain distance from the rear of the pressing mechanism, the pull plate cylinder 432 is in the ejected state, and the top plate 433 is located below and behind the locking piece 35. The pull plate cylinder 432 pulls back the telescopic pull plate 431. At this time, the top plate 433 is located directly below the locking piece 35. Then, the lifting mechanism 41 drives the telescopic pull plate 431 on the fixed mounting plate 42 to move upward, allowing the top plate 433 to push upward from the bottom of the locking piece 35, compressing the spring 37 inside the movable sleeve 33, thereby releasing the friction of the locking piece 35 on the column 32, and driving the movable sleeve 33 and the pressure arm 34 along the column 32. Move upwards to release the clamping state on mold 1.

[0031] In this embodiment, the top plate 433 is provided with a pad 434 for actuating the locking piece 35. 434 can make more precise contact with the locking plate 35 and also reduce the contact stroke.

[0032] In this embodiment, the lifting mechanism 41 includes a housing mounting base 411, a lifting column 412, and a column. 32 Drive motor 413, housing mounting base 411 is fixedly mounted on the top of frame 10 via mounting beam, lifting column 412 is vertically inserted inside housing mounting base 411 via guide rail slider, and column 32 drive motor 413 is connected to rack and pinion mounted on lifting column 412 via gear meshing.

[0033] In practical implementation, the drive motor 413 of the column 32 is connected to the rack and pinion set on the lifting column 412 through gears, thereby driving the lifting column 412 to move up and down within the housing mounting base 411. The lifting column 412 is connected to the inside of the housing mounting base 411 through the guide rail slider, so that the lifting column 412 moves up and down more smoothly and stably. In this embodiment, the fixed mounting plate 42 is provided with a piston rod end that extends and retracts downward toward the fixed mounting plate 42, which is used to press against the upper end face of the clamping mechanism. This upper end face is the upper end face of the pressure arm 34 away from the column 32.

[0034] In practical implementation, when the locking plate pulling mechanism 43 releases the locking plate 35 and pulls the movable sleeve 33 and the pressure arm 34 to move upward along the column 32, a downward pressure is applied to the upper end face of the front end of the pressure arm 34 by the abutting cylinder 424, so that the movable sleeve 33 and the pressure arm 34 slide upward on the column 32 more smoothly.

[0035] In this embodiment, at least two sets of locking plate pulling mechanisms 43 are provided on the fixed mounting plate 42, and at least two sets of clamp releasing devices 40 are provided on the top of the frame 10. This allows for the simultaneous release of multiple clamps 30 holding the mold 1, improving efficiency.

[0036] As shown in Figure 1 and Figure 7 As shown, in this embodiment, the mold-taking platform 20 is provided with a conveying device 22 for feeding and discharging material from the clamp 30 that holds the mold 1.

[0037] Specifically, the conveying device 22 includes a roller mounting base 221, a transmission roller 222, and a conveying motor 223. The roller mounting base 221 consists of two spaced-apart side plates, with multiple fixed shafts spaced along their length connecting the side plates. The transmission roller 222 is rolled on the fixed shafts, and one end of the transmission roller 222 is provided with a roller sprocket 224. The conveying motor 223 is located at the bottom of the mold-taking platform 20, and the output shaft end of the conveying motor 223 is connected to each transmission roller 222 via a chain drive.

[0038] In practical implementation, the conveying device 22 can be used to connect the mold 1 drying conveying line. After being dried, the mold 1 enters the mold removal platform 20 through the conveying device 22. The clamp 30 is released by the clamp release device 40, and the mold removal is completed, which effectively improves the continuous productivity of the production line and increases production efficiency.

[0039] Where there is no conflict, the above embodiments and features can be combined with each other.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
