Description

Technical Field

[0001] This invention relates to the field of compression molding, and in particular to a compression molding apparatus for filter plastic parts. Background Technology

[0002] Compression molding, also known as compression molding, molding or pressing, is a long-established plastic processing technology. Its core is to directly add powdered or granular raw materials into a heated mold, and then shape and solidify them by applying pressure.

[0003] In the production of filter plastic parts, traditional compression molding equipment is mostly a fixed station structure. Powder raw materials are manually fed in and then compressed into shape. After compression molding, the molded parts are then manually removed, resulting in low efficiency in filter compression molding. Summary of the Invention

[0004] To improve the low efficiency of filter compression molding, this application provides a filter plastic part compression molding apparatus.

[0005] The filter plastic part compression molding apparatus provided in this application adopts the following technical solution: A filter plastic part compression molding device includes a worktable, a fixed base fixed on the top surface of the worktable, a plurality of columns fixed on the top surface of the fixed base, a top plate provided at the top of the plurality of columns, two slide rails provided on the top surface of the fixed base, a movable seat slidably mounted on the two slide rails, a support column fixed at each corner of the top surface of the movable seat, a lower mold fixed at the top of the plurality of support columns, molding cavities opened at both ends of the top surface of the lower mold, a cylinder provided on both sides of the top surface of the top plate, the bottom end of the piston rod of the cylinder passing through the bottom surface of the top plate, an upper mold fixed at the bottom end of the piston rod of the cylinder, the upper mold being insertable into the molding cavity, and a drive mechanism for driving the movable seat to move provided on the worktable.

[0006] By adopting the above technical solution, the lower mold can reciprocate in the horizontal direction through the cooperation of the slide rail and the moving seat. Two molding cavities are set on the top surface of the lower mold. When one of the upper molds is compressing the powder in one molding cavity, powder is added to the other molding cavity. The structure design of double molding cavities and double upper molds can realize alternating operation, thereby improving the compression molding efficiency of filter plastic parts.

[0007] Preferably, cylinder two is fixed at both ends of the top surface of the movable seat, a push rod is fixed at the top end of the piston rod of cylinder two, a through hole is opened on the inner bottom surface of the molding cavity, and the top end of the push rod is inserted into the through hole.

[0008] By adopting the above technical solution, after the powder in the molding cavity is compressed and molded, cylinder two is activated. The piston rod of cylinder two drives the push rod to move upward, so that the push rod pushes the compressed and molded filter part out of the molding cavity, thereby making it easier for the staff to take out the compressed and molded filter part.

[0009] Preferably, the driving mechanism includes a fixing block fixed to the side of the movable seat, two parallel mounting blocks fixed to one side of the top surface of the fixing seat, a screw rotatably mounted between the two mounting blocks, the screw passing through the fixing block and threadedly connected to the fixing block, a motor provided on the top surface of the worktable, and the output shaft of the motor fixedly connected to one end of the screw.

[0010] By adopting the above technical solution, the motor is started, the output shaft of the motor drives the screw to rotate, the screw drives the fixed block to move, and the fixed block drives the moving seat to move along the axial direction of the screw, thereby causing the moving seat to drive the lower mold to move.

[0011] Preferably, a plurality of connecting columns are fixed to the bottom surface of the top plate, an mounting plate is fixed to the bottom surface of the plurality of connecting columns, a feeding port is provided on the top surface of the mounting plate, a feeding box is fixed to the bottom surface of the mounting plate, a feeding hole for feeding powder into the molding cavity is provided on the bottom surface of the feeding box, and a through opening is provided on the top surface of the top plate.

[0012] By adopting the above technical solution, the staff pours the powder into the feeding box through the inlet and the feeding port. When the moving seat moves the lower mold toward one side of the worktable, the forming cavity at one end of the top surface of the lower mold is aligned with the upper mold at one end of the top plate. At the same time, the forming cavity at the other end of the top surface of the lower mold corresponds to the feeding hole on the bottom surface of the feeding box, thereby realizing automatic feeding of the forming cavity and avoiding the possibility of uneven or spilled material due to manual sprinkling.

[0013] Preferably, a cylinder three is provided at one end of the top surface of the mounting plate, and a material-dispensing rake is fixed at the end of the piston rod of the cylinder three, and the material-dispensing rake is disposed inside the feeding box.

[0014] By adopting the above technical solution, cylinder three is activated, and the piston rod of cylinder three drives the material rake to move, causing the material rake to move the powder in the feeding box, thereby reducing the possibility of powder clumping in the feeding box and preventing the powder from flowing into the molding cavity.

[0015] Preferably, a connecting plate is fixed on the two columns located on one side of the movable seat, and an air gun is fixed through the side of the connecting plate. Two uprights are provided on one side of the workbench, and a receiving box is provided on the uprights.

[0016] By adopting the above technical solution, after the powder in the molding cavity is pressed and molded, cylinder three is activated, causing the piston rod of cylinder three to drive the push rod to move upward, so that the push rod pushes the molded part out of the molding cavity. Then, the air gun blows air towards the molded part, thereby blowing the molded part into the collection box, which facilitates the collection of the molded part.

[0017] Preferably, an arc-shaped block is fixed at the bottom end of the material-feeding rake.

[0018] By adopting the above technical solution, an arc-shaped block is set at the bottom of the feeding rake. When the piston rod of cylinder two drives the feeding rake to move, the feeding rake drives the arc-shaped block to move, which pushes the powder at the bottom of the feeding box to move. The arc surface of the arc-shaped block compresses the powder at the bottom of the feeding box, thereby filling the molding cavity with powder.

[0019] Preferably, the top surface of the lower mold is provided with a spiral groove on both sides, a spiral enclosure is provided in the spiral groove, and a driving component is provided on the cylinder for driving the spiral enclosure to move vertically.

[0020] By adopting the above technical solution, when cylinder one is started, the piston rod of cylinder one drives the upper mold to move downward, so that the upper mold squeezes the powder in the molding cavity. At the same time, the driving component on the piston rod of cylinder one also drives the U-shaped barrier to move upward, so that the U-shaped barrier protects the compression molding area, thereby reducing the possibility of accidental debris splashing and injuring workers during the compression molding process.

[0021] Preferably, the driving component includes a connecting rod sleeved and fixed on a piston rod of the cylinder, a rack fixed to the bottom surface of the connecting rod, through slots on both sides of the lower mold, the through slots communicating with the U-shaped slot, multiple toothed grooves vertically formed on the side of the U-shaped enclosure, gears rotatably mounted between the opposite inner surfaces of the through slots, the teeth of the gears being inserted into the toothed grooves, and the rack driving the gears to rotate.

[0022] By adopting the above technical solution, when the piston rod of cylinder one drives the upper mold to move downward, the piston rod of cylinder one also drives the connecting rod to move downward. The connecting rod drives the rack to move downward. During the downward movement of the rack, the rack drives the gear to rotate, thereby driving the gear to drive the U-shaped enclosure to move upward.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Start the motor. The motor's output shaft drives the screw to rotate. The screw drives the fixed block to move, causing the fixed block to move the moving seat along the screw's axial direction, thus realizing the reciprocating movement of the lower mold in the horizontal direction. Two molding cavities are set on the top surface of the lower mold. When one of the upper molds is compressing the powder in one molding cavity, powder is added to the other molding cavity. The dual molding cavity and dual upper mold structure design can realize alternating operation, thereby improving the compression molding efficiency of filter plastic parts. 2. The staff pours the powder into the feeding box through the inlet and the feeding port. When the moving seat moves the lower mold toward one side of the worktable, the forming cavity at one end of the top surface of the lower mold is aligned with the upper mold at one end of the top plate. At the same time, the forming cavity at the other end of the top surface of the lower mold corresponds to the feeding hole on the bottom surface of the feeding box, thereby realizing automatic feeding of the forming cavity and avoiding the possibility of uneven feeding or spillage and waste by manual feeding. 3. When the piston rod of cylinder one drives the upper mold to move downward, the piston rod of cylinder one also drives the connecting rod to move downward. The connecting rod drives the rack to move downward. During the downward movement of the rack, the rack drives the gear to rotate, which in turn drives the U-shaped barrier to move upward. This U-shaped barrier protects the compression molding area, thereby reducing the possibility of accidental debris splashing and injuring workers during the compression molding process.

[0033] Reference Figure 1 and Figure 2 Cylinder 2 3 is fixed at both ends of the top surface of the movable seat 15. A push rod 31 is fixed at the top of the piston rod of cylinder 2 3. A through hole 32 is opened on the inner bottom surface of the forming cavity 18, and the top of the push rod 31 is inserted into the through hole 32. Connecting plates 35 are sleeved on the two columns 12 located on one side of the movable seat 15. The connecting plates 35 can move vertically, and air guns 36 are fixed through the side of the connecting plates 35. Fixing bolts 37 are threaded through the side of the connecting plates 35 and are threaded to the connecting plates 35. The ends of the fixing bolts 37 abut against the outer circumferential surface of the columns 12. Two uprights 33 are provided on one side of the workbench 1, and a receiving box 34 is placed on the top of the uprights 33.

[0034] Reference Figure 1 and Figure 2A fixing block 22 is fixed to the side of the movable seat 15. Two parallel mounting blocks 23 are fixed to one side of the top surface of the fixed seat 11. A screw 24 is rotatably mounted between the two mounting blocks 23. The screw 24 passes through the fixing block 22 and is threadedly connected to the fixing block 22. A motor 25 is fixed to the top surface of the worktable 1. The output shaft of the motor 25 is fixedly connected to one end of the screw 24.

[0035] Reference Figure 2 and Figure 4 Multiple connecting pillars 4 are fixed to the bottom surface of the top plate 13. A mounting plate 41 is fixed to the bottom surface of the connecting pillars 4. A feeding port 42 is opened on the top surface of the mounting plate 41, and a feeding box 43 is fixed to the bottom surface of the mounting plate 41. The bottom surface of the feeding box 43 is in contact with the top surface of the lower mold 17. A feeding hole 44 for feeding powder into the molding cavity 18 is opened on the bottom surface of the feeding box 43. A through-hole 45 is opened on the top surface of the top plate 13, corresponding to the feeding port 42. A cylinder 46 is installed at one end of the top surface of the mounting plate 41. A material-dispensing rake 47 is fixed to the end of the piston rod of the cylinder 46. The material-dispensing rake 47 is located inside the feeding box 43, and an arc-shaped block 48 is fixed to the bottom end of the material-dispensing rake 47.

[0036] The implementation principle of the filter plastic part compression molding device in this application embodiment is as follows: The operator pours powder into the feeding box 43 through the inlet 45 and the feeding port 42, and then starts the cylinder 3 46. The piston rod of the cylinder 3 46 drives the material rake 47 to move, so that the material rake 47 moves the powder in the feeding box 43, and the arc block 48 squeezes the powder into the molding cavity 18. Then the motor 25 is started, and the output shaft of the motor 25 drives the screw 24 to rotate. The screw 24 drives the fixed block 22 to move, so that the fixed block 22 drives the moving seat 15 to move. The moving seat 15 drives the lower mold 17 to move, so that the molding cavity 18 filled with powder moves to the lower part of the upper mold 21 at one end of the top plate 13, and the molding cavity 18 at the other end of the top surface of the lower mold 17 moves to the lower part of the feeding box 43 for feeding. Then, one of the cylinders 12 at one end of the top plate 13 is activated, causing the piston rod of cylinder 22 to move the upper mold 21 downward, so that the upper mold 21 extrudes the powder in the molding cavity 18. When the piston rod of cylinder 2 moves the upper mold 21 downward, the piston rod of cylinder 2 also moves the connecting rod 52 downward. The connecting rod 52 moves the rack 53 downward. During the downward movement, the rack 53 drives the gear 55 to rotate. The gear 55 drives the U-shaped barrier 51 to move upward, so that the U-shaped barrier 51 moves out of the U-shaped groove 5. The U-shaped barrier 51 protects the compression molding area, thereby reducing the possibility of accidental flying debris injuring workers during the compression molding process. After the powder in the molding cavity 18 is molded, cylinder 2 is activated, causing the piston rod of cylinder 2 to move the upper mold 21 upward, so that the upper mold 21 is disengaged from the molding cavity 18. The rack 53 drives the gear 55 to rotate in the opposite direction, so that the loop barrier 51 moves into the loop groove 5. Then cylinder 3 is activated, and the piston rod of cylinder 3 drives the push rod 31 to move upward, so that the push rod 31 pushes out the molded part in the molding cavity 18. Then air gun 36 is activated, so that air gun 36 blows air towards the molded part, blowing the filter molded part into the receiving box 34. Then, the motor 25 is started, causing the output shaft of the motor 25 to drive the screw 24 to rotate. The screw 24 drives the fixed block 22 to move, causing the fixed block 22 to drive the moving seat 15 to move in the opposite direction. The moving seat 15 drives the lower mold 17 to move in the opposite direction, causing the molding cavity 18 filled with powder to move to the other end of the top plate 13 below the upper mold 21 for compression molding. The feeding box 43 continues to feed the molding cavity 18 from which the compression molded part is taken out, so that the structural design of the double molding cavity 18 and the double upper mold 21 can work alternately, thereby improving the compression molding efficiency of the filter plastic parts.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
