Description

Technical Field

[0001] This utility model belongs to the technical field of carbon brick production equipment, specifically relating to a pressing and molding equipment that facilitates material unloading. Background Technology

[0002] With the development of the chemical industry, the market demand for acid and alkali resistant and corrosion-resistant carbon bricks is increasing. The production process of corrosion-resistant carbon bricks mainly includes crushing, screening, grinding, mixing, molding, and curing. The carbon bricks produced are not only of high quality and durable, but also have good corrosion resistance.

[0003] Currently, in the molding process, the mixed materials need to be fed into the molding equipment for pressing, and then the pressed brick blanks are sent for curing. However, the existing molding equipment is inconvenient to unload, and after a period of use, dirt and residue easily accumulate at the bottom of the mold cavity, which is difficult to clean and can easily affect the performance and service life of the mold.

[0004] Therefore, there is an urgent need for a pressing and molding equipment that facilitates material unloading in order to solve the above problems. Utility Model Content

[0005] To address the aforementioned deficiencies in existing technologies, this utility model provides a convenient unloading compression molding device, comprising a top plate, a bottom plate, a hydraulic cylinder, an upper mold, a lower mold, an unloading mechanism, and a rotating cleaning mechanism. The top plate is located above the bottom plate, and two columns are fixed between the top plate and the bottom plate, with the two columns respectively located at the left and right ends of the top plate. The hydraulic cylinder is fixedly installed above the top plate, and the piston rod of the hydraulic cylinder passes downward through the top plate. The upper mold and the lower mold are vertically opposite each other and located between the top plate and the bottom plate. The top of the upper mold is fixedly connected to the piston rod of the hydraulic cylinder, and several pressure blocks are provided at the bottom of the upper mold. The lower mold is fixedly connected between the two columns, and the top of the lower mold has the same number of mold cavities as the pressure blocks, and the mold cavities match the pressure blocks.

[0006] The unloading mechanism includes a lifting cylinder, a lifting plate, and several pusher plates. The lifting cylinder is fixedly mounted on the base plate. The bottom surface of the lifting plate is fixedly connected to the piston rod of the lifting cylinder. The number of pusher plates is the same as the number of mold cavities. Each pusher plate is located at the bottom of the corresponding mold cavity. Each pusher plate has a support rod fixed at its bottom, and the bottom end of the support rod extends out of the lower mold and is fixedly connected to the top surface of the lifting plate. When the piston rod of the lifting cylinder is stretched to the maximum position, the top surface of the pusher plate is at the same height as the top of the mold cavity (i.e., the top surface of the lower mold).

[0007] The rotating cleaning mechanism is mounted on the right-side column and is used to clean the unloading plate that is lifted to the top of the mold cavity after unloading.

[0008] Optionally, the rotating cleaning mechanism includes a connecting arm and a cleaning assembly. One end of the connecting arm is rotatably connected to a column. The cleaning assembly includes a mounting plate, a forward and reverse motor, two slide rails, a guide rod, a threaded rod, and two sliders. The mounting plate is fixed below the other end of the connecting arm. Two baffles are fixed on the left and right sides below the mounting plate. The forward and reverse motor is installed on the outside of one of the baffles. The two slide rails are respectively set on the front and rear sides of the bottom surface of the mounting plate. The guide rod and the threaded rod are parallel to each other and are respectively set below the two slide rails. The guide rod is fixed between the two baffles. The threaded rod is rotatably connected between the two baffles, and one end of the threaded rod is drivenly connected to the output shaft of the forward and reverse motor. The guide rod and the threaded rod pass through the two sliders respectively, and one slider is slidably connected to the threaded rod through the nut pair of the threaded rod. The tops of the two sliders are slidably connected to the two slide rails respectively. A cleaning roller is rotatably connected between the two sliders.

[0009] Optionally, a reinforcing rod is provided between the connecting arm and the column. The reinforcing rod is inclined, with the higher end of the reinforcing rod rotatably connected to the column and the lower end of the reinforcing rod fixed to the connecting arm.

[0010] Specifically, the reinforcing rod can improve the stability of the rotating cleaning mechanism.

[0011] Optionally, an inverted L-shaped limiting rod is also provided on the right-side column to limit the reinforcing rod.

[0012] Specifically, when dust removal is required, the connecting arm is rotated to make the cleaning component rotate inward around the column. The limiting rod blocks and limits the reinforcing rod, ensuring that the cleaning component is positioned directly above the lower mold, which facilitates subsequent cleaning.

[0013] Optionally, the contact surface between the pusher plate and the bottom of the mold cavity is stepped.

[0014] Optionally, a limit block is provided on the top surface of the lifting platform.

[0015] Specifically, the limit block is made of rubber, which can prevent the lifting plate from colliding with the lower mold during the lifting process, thus playing a buffering and protective role.

[0016] Optionally, ash collection troughs are provided at both the left and right ends of the lower mold, and the ash collection troughs are located on the outside of several mold cavities, with a drawer provided in each ash collection trough.

[0017] Specifically, a dust collection tray can be used to collect the dust and dirt swept up, and finally, the drawer can be taken out to dispose of the dust and dirt.

[0018] This invention also includes other components that enable the normal operation of a convenient unloading compression molding device, all of which are conventional techniques in the field. Furthermore, any devices or components not specified in this invention employ conventional techniques in the field, such as hydraulic cylinders, lifting cylinders, and forward / reverse motors.

[0019] The working principle of this invention is as follows: First, pressing and molding are performed. Material is added to each cavity of the lower mold. The hydraulic cylinder is controlled to extend the piston rod, causing the upper mold to move downwards. The pressing blocks then press the material in the mold cavities. After pressing, unloading begins. The hydraulic cylinder is controlled to retract the piston rod, causing the upper mold to move upwards. Then, the lifting cylinder is controlled to extend the piston rod, driving the lifting plate upwards, which in turn pushes the pusher plates in each mold cavity upwards, pushing the pressed brick blanks out of the mold cavity, completing demolding and unloading. After a period of use, dust removal begins. The piston rod of the lifting cylinder is kept extended, raising the pusher plates to the top of the mold cavity. Dirt and residue accumulate on the upper part of the mold. Rotate the connecting arm inward to move the cleaning assembly directly above the lower mold. At this point, the bottom of the cleaning roller should be just touching the lower mold. Start the forward and reverse motor. The output shaft of the forward and reverse motor rotates forward first, driving the threaded rod to rotate, causing the slider to move from right to left. This, in turn, drives the cleaning roller to sweep the dirt and residue on the push plate from right to left into the dust collection trough on the left. Then, control the output shaft of the forward and reverse motor to rotate in reverse, driving the cleaning roller to sweep the dirt and residue on the push plate from left to right into the dust collection trough on the right. Repeat this operation until the push plate is clean. Finally, take out the drawer and clean out the dust and dirt inside.

[0020] The beneficial effects of this utility model are that the material can be pressed into shape through the top plate, bottom plate, hydraulic cylinder, upper mold and lower mold; the unloading mechanism can push the pressed brick blank out of the mold cavity, which is convenient for demolding and unloading. At the same time, it can also push out the dirt and residue at the bottom of the mold cavity. Then, through the rotating cleaning mechanism, the push plate that has been lifted to the top of the mold cavity is cleaned, and the dirt and residue are cleaned into the ash collection trough for easy cleaning.

[0030] like Figure 1-5 As shown, this utility model embodiment provides a pressing and molding equipment for convenient unloading, including a top plate 1, a bottom plate 2, a hydraulic cylinder 3, an upper mold 4, a lower mold 5, an unloading mechanism, and a rotating cleaning mechanism. The top plate 1 is located above the bottom plate 2. Two columns 6 are fixed between the top plate 1 and the bottom plate 2, and the two columns 6 are respectively located at the left and right ends of the top plate 1. The hydraulic cylinder 3 is fixedly installed above the top plate 1, and the piston rod of the hydraulic cylinder 3 passes downward through the top plate 1. The upper mold 4 and the lower mold 5 are vertically opposite each other and located between the top plate 1 and the bottom plate 2. The top of the upper mold 4 is fixedly connected to the piston rod of the hydraulic cylinder 3. Several pressure blocks 7 are provided at the bottom of the upper mold 4. The lower mold 5 is fixedly connected between the two columns 6. The top of the lower mold 5 is provided with the same number of mold cavities 8 as the pressure blocks 7, and the mold cavities 8 match the pressure blocks 7.

[0031] The unloading mechanism includes a lifting cylinder 9, a lifting plate 10, and several pusher plates 11. The lifting cylinder 9 is fixedly mounted on the base plate 2. The bottom surface of the lifting plate 10 is fixedly connected to the piston rod of the lifting cylinder 9. The number of pusher plates 11 is the same as the number of mold cavities 8. Each pusher plate 11 is located at the bottom of the corresponding mold cavity 8. The contact surface between the pusher plate 11 and the bottom of the mold cavity 8 is stepped. Each pusher plate 11 has a support rod 12 fixed at its bottom. The bottom end of the support rod 12 passes through the lower mold 5 and is fixedly connected to the top surface of the lifting plate 10. When the piston rod of the lifting cylinder 9 is stretched to the maximum position, the top surface of the pusher plate 11 is at the same height as the top of the mold cavity 8 (i.e., the top surface of the lower mold 5).

[0032] In addition, a limit block 13 is provided on the top surface of the lifting plate 10. The limit block 13 is made of rubber, which can prevent the lifting plate 10 from colliding with the lower mold 5 during the lifting process and play a buffering and protection role.

[0033] The rotating cleaning mechanism is rotatably mounted on the right-side column 6. The rotating cleaning mechanism includes a connecting arm 14 and a cleaning assembly 15. One end of the connecting arm 14 is rotatably connected to the column 6. The cleaning assembly 15 includes a mounting plate 16, a forward / reverse motor 17, two slide rails 18, a guide rod 19, a threaded rod 20, and two sliders 21. The mounting plate 16 is fixed below the other end of the connecting arm 14. Two baffles 22 are fixed on the left and right sides below the mounting plate 16. The forward / reverse motor 17 is mounted on the outside of one of the baffles 22. The two slide rails 18 are respectively located at the front and rear of the bottom surface of the mounting plate 16. On both sides, guide rod 19 and threaded rod 20 are parallel to each other and are respectively located below two slide rails 18. Guide rod 19 is fixed between two baffles 22, and threaded rod 20 is rotatably connected between two baffles 22. One end of threaded rod 20 is connected to the output shaft of forward and reverse motor 17. Guide rod 19 and threaded rod 20 pass through two sliders 21 respectively, and one slider 21 is slidably connected to threaded rod 20 through the nut pair of threaded rod 20. The tops of the two sliders 21 are slidably connected to the two slide rails 18 respectively. A cleaning roller 23 is rotatably connected between the two sliders 21.

[0034] In addition, a reinforcing rod 24 is provided between the connecting arm 14 and the column 6. The reinforcing rod 24 is inclined, with the higher end of the reinforcing rod 24 rotatably connected to the column 6 and the lower end fixed to the connecting arm 14. The reinforcing rod 24 can improve the stability of the rotating cleaning mechanism. An inverted L-shaped limiting rod 25 is also provided on the column 6 on the right side to limit the reinforcing rod 24. When dust removal is required, the connecting arm 14 is rotated, causing the cleaning component 15 to rotate inward around the column 6. The limiting rod 25 blocks and limits the reinforcing rod 24, ensuring that the cleaning component 15 is exactly above the lower mold 5, which is convenient for subsequent cleaning. Dust collection grooves 26 are provided at both ends of the lower mold 5, and the dust collection grooves 26 are located on the outside of several mold cavities 8. Each dust collection groove 26 is equipped with a drawer, which can be used to collect the dust and dirt swept off. Finally, the drawer is taken out to collect and dispose of the dust and dirt.

[0035] The working principle of this utility model is as follows: First, pressing and molding are performed. The material is added to each cavity 8 of the lower mold 5. The hydraulic cylinder 3 is controlled to extend the piston rod, driving the upper mold 4 to move downward. The pressure block 7 is used to press the material in the cavity 8. After pressing is completed, unloading begins. The hydraulic cylinder 3 is controlled to retract the piston rod, driving the upper mold 4 to move upward. Then, the lifting cylinder 9 is controlled to extend the piston rod, driving the lifting plate 10 to move upward, which in turn pushes the pusher plate 11 in each cavity 8 to move upward, pushing the pressed brick blank 27 out of the cavity 8, completing the demolding and unloading. After a period of use, dust removal begins. The piston rod of the lifting cylinder 9 is kept in the extended state, and the pusher plate 11 is raised to the top of the cavity 8. At this time, dirt accumulates on the pusher plate 11. To remove dirt and residue, rotate the connecting arm 14 inward to move the cleaning assembly 15 directly above the lower mold 5. At this point, the bottom of the cleaning roller 23 should be just touching the lower mold 5. Start the forward and reverse motor 17. The output shaft of the forward and reverse motor 17 will rotate forward first, driving the threaded rod 20 to rotate, causing the slider 21 to move from right to left. This will then drive the cleaning roller 23 to sweep the dirt and residue on the push plate 11 from right to left into the dust collection trough 26 on the left. After that, control the output shaft of the forward and reverse motor 17 to rotate in reverse, driving the cleaning roller 23 to sweep the dirt and residue on the push plate 11 from left to right into the dust collection trough 26 on the right. Repeat this operation until the push plate 11 is clean. Finally, take out the drawer and clean out the dust and dirt inside.

[0036] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
