Description

Technical Field

[0001] The utility model relates to the technical field of casting sand molds, in particular to a sand box tooling for casting sand molds. Background Technique

[0002] In the patent document with the published publication number CN216176459U, a sand box tooling for casting sand molds is disclosed, including a lower mold. Four limiting rods are installed on the top of the lower mold, and a push plate is installed inside the lower mold. Support rods are installed on both symmetric sides of the lower mold. An electric push rod is installed on one side of the support rod, a moving rod is installed at the telescopic end of the electric push rod, and one end of the moving rod is connected to the push plate. A top cover is installed on the top of the upper mold, and an installation groove is opened on one side of the top of the lower mold close to the limiting rod. In the utility model, the electric push rod drives the moving rod to move, and the moving rod drives the push plate to move, so that the push plate pushes the sand mold formed inside the upper mold and the lower mold, and the sand mold moves to the outside of the device. When the user needs to take out the sand mold, it is not necessary for the user to manually take out the sand mold, so that the formed sand mold is not easily damaged and does not need to be repaired again later, reducing the casting difficulty of the sand mold and improving the casting efficiency of the sand mold.

[0003] In the above device during use, the top cover is placed above the upper mold to extrude the sand, so that the sand is formed under the cooperation of the workpiece. However, the top cover cannot well extrude the sand, or rather, it still requires manual extrusion of the top cover to extrude the sand. Manual extrusion is not only inefficient but also has unstable effects. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sand box tooling for casting sand molds, which solves the problems raised in the background technique.

[0005] The embodiment of the present application provides a sand box tooling for casting sand molds, including a base. A lower mold is fixedly installed at the top end of the base, an upper mold is fixedly connected to the top end of the lower mold, a vertical rod is fixedly installed on one side of the base, a cross plate is fixedly installed at the top of the vertical rod, two groups of hydraulic rods are fixedly installed at the bottom end of the cross plate, an extrusion plate is fixedly installed at the telescopic end of the hydraulic rods, and vibration motors are fixedly installed on both sides of the connection between the lower mold and the upper mold.

[0006] By adopting the above technical solution, sand is added to the lower mold, a workpiece is added to the upper mold, and then the sand is filled inside the upper mold. Then the vibration motors are started, and the vibration of the vibration motors makes the sand inside the lower mold and the upper mold arranged more closely. Then two groups of hydraulic rods are started, and the two groups of hydraulic rods drive the extrusion plate to extrude and compact the sand inside the upper mold. To ensure the compaction effect, the above steps are repeated more than three times. By automatically vibrating and extruding the sand inside the lower mold and the upper mold, the compaction efficiency of the sand is greatly improved, and the compaction effect is good.

[0007] Optionally, both the length and width of the extrusion plate are smaller than those of the inner circle of the upper mold.

[0008] By adopting the above technical solution, since both the length and width of the extrusion plate are smaller than those of the inner circle of the upper mold, it is beneficial for the extrusion plate to fall smoothly and extrude the sand on the top of the upper mold.

[0009] Optionally, a chute is provided inside the lower mold, and a cutting plate is slidably connected to the inside of the lower mold through the chute.

[0010] By adopting the above technical solution, after the sand mold is formed, by pulling the cutting plate to drive the through hole to move, the cutting plate cuts the formed sand mold, separating the sand mold into the upper sand mold and the lower sand mold, enabling the user to avoid cutting after taking out the sand mold and preventing damage to the sand mold during the cutting process, further reducing the damage probability of the sand mold, further reducing the casting difficulty of the sand mold, and further improving the casting efficiency of the sand mold.

[0011] Optionally, a shock absorber is fixedly installed at the bottom end of the base, and the shock absorber is made of rubber.

[0012] By adopting the above technical solution, due to the good shock absorption effect of the rubber material, the impact on external facilities caused by the operation of the vibration motor is reduced.

[0013] Optionally, an anti-slip seat is fixedly installed at the bottom end of the shock absorber.

[0014] By adopting the above technical solution, the anti-slip effect of this device is improved through the anti-slip seat, which is beneficial to improving the stability of this device during operation.

[0015] Optionally, a handle is fixedly installed on one side of the cutting plate.

[0016] By adopting the above technical solution, the handle facilitates providing a hand action point when pulling the cutting plate, improving the practicality during use.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] Add sand to the lower mold, add the workpiece to the upper mold, then fill the sand inside the upper mold, and then start the vibration motor. The vibration of the vibration motor arranges the sand inside the lower mold and the upper mold more closely. Then start the two groups of hydraulic rods, and the two groups of hydraulic rods drive the extrusion plate to extrude and compact the sand inside the upper mold. To ensure the compaction effect, the above steps are repeated more than three times. By automatically vibrating and extruding the sand inside the lower mold and the upper mold, the compaction efficiency of the sand is greatly improved, and the compaction effect is good.

[0024] Please refer to Figures 1-3 , the present utility model provides a technical solution: including a base 1, a lower die 2 is fixedly installed at the top of the base 1, an upper die 3 is fixedly connected to the top of the lower die 2, a vertical rod 4 is fixedly installed on one side of the base 1, a cross plate 5 is fixedly installed at the top of the vertical rod 4, two groups of hydraulic rods 6 are fixedly installed at the bottom end of the cross plate 5, an extrusion plate 8 is fixedly installed at the telescopic end of the hydraulic rod 6, and vibration motors 9 are fixedly installed on both sides of the connection between the lower die 2 and the upper die 3;

[0025] In this technical solution, sand is added to the lower die 2, a workpiece is added to the upper die 3, and then the sand is filled inside the upper die 3. Then, the vibration motors 9 are started, and the vibration of the vibration motors 9 makes the sand inside the lower die 2 and the upper die 3 arranged more closely. Then, the two groups of hydraulic rods 6 are started, and the two groups of hydraulic rods 6 drive the extrusion plate 8 to extrude and compact the sand inside the upper die 3. In order to ensure the compaction effect, the above steps are repeated more than three times. By automatically vibrating and extruding the sand inside the lower die 2 and the upper die 3, the compaction efficiency of the sand is greatly improved, and the compaction effect is good.

[0026] In some technical solutions, as Figure 1 shown, both the length and width of the extrusion plate 8 are smaller than the length and width of the inner circle of the upper die 3.

[0027] During use, since both the length and width of the extrusion plate 8 are smaller than the length and width of the inner circle of the upper die 3, it is beneficial for the extrusion plate 8 to fall smoothly and extrude the sand on the top of the upper die 3.

[0028] In some technical solutions, as Figure 1 shown, a chute is opened inside the lower die 2, and a cutting plate 11 is slidably connected to the inside of the lower die 2 through the chute.

[0029] During use, after the sand mold is formed, the cutting plate 11 is pulled to drive the through hole 13 to move, so that the cutting plate 11 cuts the formed sand mold, separating the upper sand mold and the lower sand mold at the separation position of the sand mold, enabling the user to cut the sand mold without taking it out, avoiding damage to the sand mold during the cutting process, further reducing the damage probability of the sand mold, further reducing the casting difficulty of the sand mold, and further improving the casting efficiency of the sand mold.

[0030] In some technical solutions, as Figure 1 shown, a shock absorber 15 is fixedly installed at the bottom end of the base 1, and the shock absorber 15 is made of rubber.

[0031] During use, due to the good shock absorption effect of the rubber material, the impact on external facilities caused by the operation of the vibration motor 9 is reduced.

[0032] In some technical solutions, as Figure 1 shown, an anti-slip seat 16 is fixedly installed at the bottom end of the shock absorber 15.

[0033] During use, the anti-slip effect of this device is improved through the anti-slip seat 16, which is beneficial to improving the stability of this device during operation.

[0034] In some technical solutions, as Figure 1 shown, a handle 14 is fixedly installed on one side of the cutting plate 11.

[0035] During use, the handle 14 facilitates providing a hand action point when pulling the cutting plate 11, improving the practicality during use.

[0036] Working principle: Add sand into the lower mold 2, add the workpiece into the upper mold 3, then fill the sand inside the upper mold 3. Then start the vibration motor 9. The vibration of the vibration motor 9 makes the sand inside the lower mold 2 and the upper mold 3 arrange more closely. Then start two groups of hydraulic rods 6, and the two groups of hydraulic rods 6 drive the extrusion plate 8 to extrude and compact the sand inside the upper mold 3. In order to ensure the compaction effect, the above steps are repeated more than three times. By automatically vibrating and extruding the sand inside the lower mold 2 and the upper mold 3, the compaction efficiency of the sand is greatly improved, and the compaction effect is good. Since the length and width of the extrusion plate 8 are both smaller than the length and width of the inner circle of the upper mold 3, it is beneficial for the extrusion plate 8 to fall smoothly to extrude the sand on the top of the upper mold 3. After the sand mold is formed, by pulling the cutting plate 11 to drive the through hole 13 to move, the cutting plate 11 cuts the formed sand mold, separating the sand mold into the upper sand mold and the lower sand mold, so that the user does not need to take out the sand mold for cutting, avoiding damage to the sand mold during the cutting process, further reducing the damage probability of the sand mold, further reducing the casting difficulty of the sand mold, and further improving the casting efficiency of the sand mold. The rubber material has a good damping effect, reducing the impact on external facilities when the vibration motor 9 works. The anti-slip seat 16 improves the anti-slip effect of this device, which is beneficial to improving the stability of this device during operation. The handle 14 facilitates providing a hand action point when pulling the cutting plate 11, improving the practicability during use.
