Description

Technical Field

[0001] This utility model relates to the field of compaction machine technology, specifically a compaction machine for sand casting. Background Technology

[0002] Sand casting is a process in which casting sand mixed with a molding sand binder is injected into a mold, and other metal materials are added appropriately to bind the loose sand grains. The sand is then subjected to high temperature and high pressure to solidify its shape, and then removed from the mold, with the edges trimmed and polished.

[0003] The function of a compactor is to press the upper and lower molds together when they are closed to prevent the mold from opening and to help the internal castings to be shaped. Usually, the piston rod is controlled by a cylinder to vertically lift and lower the parts to press them. Such mechanical equipment can often only press a single mold group at a time, which makes it difficult to improve the efficiency of pressing and shaping. It is also inconvenient to pick up and load materials.

[0004] Now, a novel sand casting compactor is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a compactor for sand casting to solve the problem of low compaction efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand casting compactor, comprising a base plate and a transverse groove. A transverse groove is provided at the center of the base plate, and a transverse shaft is movably connected between the left and right sides of the transverse groove. Right-angle gears are fixed to the two outer sides of the transverse shaft, and two movable right-angle gears are fixed to the two upper sides of the transverse groove. A motor is fixed to the left side of the base plate. Threaded sleeves are movably connected to the two sides of the center of the top of the base plate, and a lead screw is threaded into the inner thread of each threaded sleeve. A clamping plate is fixed to the top of the lead screw. A horizontal plate is fixed at the center of the lead screws, and a circular groove is provided at the center of the horizontal plate. A column is fixed at the center of the top of the base plate. A retaining ring is fixed above the outside of the column. A motor is fixed above the inside of the column. A table is movably connected to the top of the column. Slots are provided on both sides of the bottom of the table. A side rod is fixed to the left side of the top of the base plate. A top plate is fixed above the right side of the side rod. A cylinder is fixed inside the top plate. A pressure mold is fixed at the bottom of the piston rod of the cylinder. Bottom molds are placed on both sides of the top of the table.

[0007] As a further technical solution of this utility model, the right side of the output end of the first motor is fixedly connected to the horizontal shaft, and the first right-angle gear is meshed and connected to the right side below the second right-angle gear.

[0008] As a further technical solution of this utility model, the top of the right-angle gear II is fixedly connected to the bottom of the threaded sleeve, the circular groove is sleeved on the outside of the column, and the top of the output shaft of the motor I is fixedly connected to the table body.

[0009] As a further technical solution of this utility model, fixing plates are fixed on both sides of the center of the top of the table body, and screws are fixed on the front and rear ends of the sides of the fixing plates. A pressure plate is sleeved between the front and rear ends of the screws, and holes are provided at the front and rear ends of the pressure plate. A nut is threaded to the right side of the screws.

[0010] As a further technical solution of this utility model, the screw is embedded between the hole and the nut, and the inner wall of the nut matches the outer wall of the screw.

[0011] As a further technical solution of this utility model, a through groove is provided inside the right side of the top plate, a limit rod is fixed at the center of the top of the table body, and an insertion hole is provided between the upper and lower surfaces of the limit rod, and a pin is inserted and fixed in the insertion hole. A through hole is provided inside the upper right corner of the mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the compactor for sand casting not only realizes rapid loading and unloading and pressing, and adjusts the structure of the fixed mold, but also restricts the downward movement of the cylinder piston rod;

[0013] (1) By fixing a card plate at the top of the screw, the table body is controlled by motor 2 and rotates above the column. After the table body stops rotating, motor 1 is started and the horizontal shaft is rotated. The right-angle gear 1 on both sides of the horizontal shaft pushes the corresponding right-angle gear 2. The threaded sleeve fixed at the top of the right-angle gear 2 can lift the screw on both sides of the horizontal plate, forcing the card plate to be embedded in the slot, preventing the table body from continuing to rotate. The left side of the table body is used for compaction and shaping, while the right side is used for loading and unloading materials.

[0014] (2) By placing bottom molds on both sides of the top of the table, the bottom molds are placed on both sides of the top of the table. The pressure plate inserted between the screws is moved until the pressure plate and the fixing plate are symmetrically engaged on both sides of the bottom mold. Then, the nuts are screwed in for reinforcement and locking. The fixing structure can be adjusted according to the specifications of the bottom mold to prevent the bottom mold from detaching from the table and to prevent the bottom mold from shifting during pressing. This makes it easy to install and replace molds of different sizes.

[0015] (3) By fixing a limit rod at the center of the top of the table, the through groove on the right side of the top plate is fitted to the limit rod, and the lower limit rod is also embedded in the through hole. The insertion hole can be selected and the pin can be inserted for limiting. When the cylinder sinks the mold with the piston rod, it forces the mold to enter the bottom mold. The pin restricts the sinking of the mold, avoiding excessive pressing of the mold and damage to the mold and casting. It can also avoid excessive sinking of the mold according to the lifting requirements. Attached Figure Description

The transverse groove 2 is located at the center of the base plate 1, and a transverse shaft 5 is movably connected between the left and right sides of the transverse groove 2. Right-angle gears 3 are fixed to the two outer sides of the transverse shaft 5, and right-angle gears 4 are movably connected to the two upper sides of the transverse groove 2. A motor 7 is fixed to the left side of the base plate 1. Threaded sleeves 19 are movably connected to the two sides of the center of the top of the base plate 1, and screw rods 18 are threaded into the inner threads of the threaded sleeves 19. A clamping plate 17 is fixed to the top of the screw rods 18. A horizontal plate 21 is fixed at the center, and a circular groove 23 is provided at the center of the horizontal plate 21. A column 6 is fixed at the center of the top of the base plate 1. A retaining ring 22 is fixed above the outside of the column 6. A motor 20 is fixed above the inside of the column 6. A table body 9 is movably connected to the top of the column 6. A slot 16 is provided on both sides of the bottom of the table body 9. A side rod 8 is fixed on the left side of the top of the base plate 1. A top plate 10 is fixed above the right side of the side rod 8. A cylinder 12 is fixed inside the top plate 10. A pressure mold 11 is fixed at the bottom of the piston rod of the cylinder 12. A bottom mold 15 is placed on both sides of the top of the table body 9.

[0023] The right side of the output end of motor 7 is fixedly connected to the horizontal shaft 5. Right angle gear 3 is meshed and connected to the right side below right angle gear 4. The top of right angle gear 4 is fixedly connected to the bottom of threaded sleeve 19. Circular groove 23 is sleeved on the outside of column 6. The top of the output shaft of motor 7 is fixedly connected to table body 9.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the table body 9 is controlled by motor 20 and rotates above the column 6. After the table body 9 stops rotating, motor 7 is started and the horizontal shaft 5 is rotated. The right-angle gears 3 on both sides of the horizontal shaft 5 push the corresponding right-angle gears 4. The threaded sleeve 19 fixed at the top of the right-angle gears 4 is rotated, which can lift the screw rods 18 on both sides of the horizontal plate 21, forcing the card plate 17 to be embedded in the card slot 16, preventing the table body 9 from continuing to rotate.

[0025] Fixing plates 27 are fixed on both sides of the top center of the table body 9, and screws 24 are fixed on the front and rear sides of the fixing plates 27, respectively. A pressure plate 26 is sleeved between the front and rear of the screws 24, and holes 28 are provided at the front and rear of the pressure plate 26. A nut 25 is threaded on the right side of the screws 24, and the screws 24 are embedded between the holes 28 and the nut 25. The inner wall of the nut 25 matches the outer wall of the screws 24.

[0026] Specifically, such as Figure 1 and Figure 3As shown, place the bottom mold 15 on both sides of the top of the table body 9, move the pressure plate 26 that is inserted between the screws 24, and wait for the pressure plate 26 and the fixing plate 27 to be symmetrically engaged on both sides of the bottom mold 15. Then screw in the nut 25 for reinforcement and locking. The fixing structure can be adjusted according to the specifications of the bottom mold 15 to prevent the bottom mold 15 from falling off the table body 9 and to prevent the bottom mold 15 from shifting during pressing.

[0027] A through groove 14 is provided inside the right side of the top plate 10. A limit rod 13 is fixed at the center of the top of the table body 9. An insertion hole 29 is provided between the upper and lower surfaces of the limit rod 13. A pin 30 is inserted and fixed in the insertion hole 29. A through hole 31 is provided inside the upper right corner of the mold 11.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the through groove 14 on the right side of the top plate 10 is fitted onto the limiting rod 13, and the lower limiting rod 13 is also embedded in the through hole 31. The insertion hole 29 can be selected and the pin 30 can be inserted for limiting. When the cylinder 12 lowers the pressing mold 11 with the piston rod, it forces the pressing mold 11 into the bottom mold 15. The pin 30 restricts the sinking of the pressing mold 11 to avoid the pressing mold 11 pressing too much and damaging the mold and casting.

[0029] Working principle: In use, the bottom mold 15 is first placed on both sides of the top of the table body 9. The pressure plate 26, which is inserted between the screws 24, is moved until the pressure plate 26 and the fixing plate 27 are symmetrically engaged on both sides of the bottom mold 15. Then, the nuts 25 are screwed in for reinforcement and locking. The fixing structure can be adjusted according to the specifications of the bottom mold 15 to prevent the bottom mold 15 from detaching from the table body 9. The table body 9 is controlled by motor 20 and rotates above the column 6. After the table body 9 stops rotating, motor 7 is started and the horizontal shaft 5 is rotated. The right-angle gears 3 on both sides of the outer side of the horizontal shaft 5 are used to... Pushing the corresponding right-angle gear 4, rotating the threaded sleeve 19 fixed at the top of the right-angle gear 4 can lift the lead screws 18 on both sides of the horizontal plate 21, forcing the clamping plate 17 to be embedded in the clamping groove 16, preventing the table body 9 from continuing to rotate, facilitating loading and unloading and pressing. The through groove 14 on the right side of the top plate 10 is fitted onto the limiting rod 13, and the lower limiting rod 13 is also embedded in the through hole 31. The insertion hole 29 can be selected and the pin 30 can be inserted for limiting. When the cylinder 12 lowers the pressing mold 11 with the piston rod, it forces the pressing mold 11 into the bottom mold 15, and the pin 30 restricts the sinking of the pressing mold 11.
