Description

Technical Field

[0001] This utility model relates to the field of sand core impregnation technology, and more specifically, to a sand core impregnation device. Background Technology

[0002] Core coating refers to immersing sand cores in a specific liquid to coat the surface of the sand cores, thereby increasing the smoothness of the surface.

[0003] In the existing sand core impregnation process, the sand core needs to be clamped to prevent it from floating and shaking during impregnation. However, because the shape and size of the sand core can vary as needed, the clamping structure cannot be flexibly adapted. Different sizes and shapes of sand cores result in lower clamping effect or failure to clamp. Utility Model Content

[0004] The purpose of this invention is to provide a sand core impregnation and coating device, which solves the problem that sand cores tend to float in the liquid during impregnation and coating, and that existing clamping structures cannot adapt to sand cores of different shapes and sizes, resulting in poor versatility.

[0006] Preferably, the grid arranged in a "cross" in the middle of the grid frame is a long strip with arc-shaped ends.

[0007] Preferably, the mating block further includes a mating groove and a pin, the mating groove being disposed at the bottom of the mating block and the pin being connected to both sides of the mating block.

[0008] Preferably, the fitting groove matches the long strips arranged in the middle of the grid frame.

[0009] Preferably, the threaded pins penetrate both sides of the interlocking block and fit into the long strips arranged in the middle of the grid frame.

[0010] Preferably, the limiting component includes a limiting block and an abutment block, the limiting block being connected to the top of the fitting block and the abutment block being disposed on one side of the limiting block.

[0011] Preferably, the limiting block is connected to the top of the fitting block via hinge shafts on both sides of the bottom, and the hinge shafts on both sides of the bottom of the limiting block are connected to the grooves on both sides of the top of the fitting block via torsion springs.

[0012] Preferably, the abutment block is an arc-shaped elongated protrusion located on one side of the limiting block.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. The fitting block in the device can be installed at any position on the placement frame to match the shape of the sand core. Then, the limiting component on the fitting block is used to fit and limit the top edge of the sand core. When the sand core enters the dip coating tank, it shakes due to buoyancy.

[0018] The following is combined Figures 1 to 3 This utility model will be described in detail.

[0019] A sand core impregnation device includes a body 1, an impregnation tank 101 on the top of the body 1, an electric telescopic rod 102 connected above the body 1, a placement frame 2 at the bottom of the electric telescopic rod 102, a grid frame 201 at the bottom of the placement frame 2, a fitting block 202 connected to the middle of the grid frame 201, a limiting component connected to the top of the fitting block 202, and the limiting component swinging along the top of the fitting block 202.

[0020] First, pour liquid for dipping sand cores into the dipping tank 101 at the top of the main body 1. Then, place the sand cores to be dipped onto the placement rack 2 at the bottom of the electric telescopic rod 102. Then, start the electric telescopic rod 102 to extend and retract, so that the sand cores on the placement rack 2 sink into the dipping tank 101, allowing the liquid inside to complete the dipping of the sand cores.

[0021] Furthermore, the grid arranged in a "cross" shape in the middle of the grid frame 201 consists of long strips with arc-shaped ends.

[0022] The bottom of the placement rack 2 is provided with a grid rack 201, which allows liquid to seep into the bottom of the grid rack 201 and contact the bottom of the sand core. Then, at any position of the long grid of the grid rack 201, the interlocking block 202 is connected. The interlocking block 202 cooperates with the grid rack 201 through the interlocking groove 2021 at the bottom. Then, the pin 2022 is inserted to press against both sides of the long grid of the grid rack 201 to limit the connection of the interlocking block 202.

[0023] Furthermore, the interlocking block 202 also includes an interlocking groove 2021 and a pin 2022. The interlocking groove 2021 is located at the bottom of the interlocking block 202, and the pin 2022 is connected to both sides of the interlocking block 202. The interlocking groove 2021 cooperates with the long strips arranged in the middle of the grid frame 201. The pin 2022 is threaded through both sides of the interlocking block 202 and fits against the long strips arranged in the middle of the grid frame 201. Furthermore, the limiting component includes a limiting block 2023 and an abutment block 2024. The limiting block 2023 is connected to the top of the interlocking block 202, and the abutment block 2024 is located on one side of the limiting block 2023. The limiting block 2023 is connected to the top of the interlocking block 202 through hinge shafts on both sides of its bottom. The hinge shafts on both sides of the bottom of the limiting block 2023 are connected to the grooves on both sides of the top of the interlocking block 202 through torsion springs. The abutment block 2024 is an arc-shaped long strip protrusion located on one side of the limiting block 2023.

[0024] Meanwhile, a limiting block 2023 is also provided on the top of the interlocking block 202. The limiting block 2023 is connected to the interlocking block 202 via a hinge shaft. At the same time, a torsion spring is provided at the end of the hinge shaft connected to the interlocking block 202. The elasticity of the torsion spring allows the limiting block 2023 to initially tilt to one side. When the interlocking block 202 is attached to the sand core and connected to the grid frame 201, the limiting block 2023 will allow the abutment block 2024 to abut against the top of the sand core through the restoring elasticity of the torsion spring. At the same time, the degree of deflection of the limiting block 2023 can accommodate sand cores of different heights to prevent the sand core from shaking and falling off the placement frame 2 due to buoyancy when it enters the dipping tank 101.

[0025] The following is a specific implementation process of this utility model. First, pour liquid for impregnating sand cores into the impregnation tank 101 at the top of the main body 1. Then, place the sand cores to be impregnated on the placement rack 2 at the bottom of the electric telescopic rod 102. Then, start the electric telescopic rod 102 to extend and retract, so that the sand cores on the placement rack 2 sink into the impregnation tank 101, allowing the liquid inside to complete the impregnation of the sand cores.

[0026] The bottom of the placement rack 2 is provided with a grid rack 201, allowing liquid to seep from the bottom of the grid rack 201 and contact the bottom of the sand core. Then, at any position on the long grid of the grid rack 201, a fitting block 202 is connected. The fitting block 202 engages with the grid rack 201 through a fitting groove 2021 at its bottom, and then a pin 2022 is inserted to press against both sides of the long grid of the grid rack 201, thus limiting the connection of the fitting block 202. Simultaneously, a limiting block 2023 is provided on the top of the fitting block 202, and the limiting block 2023 is connected to the fitting via a hinge shaft. On the assembly block 202, a torsion spring is also provided at the end where the hinge shaft is connected to the assembly block 202. The elasticity of the torsion spring allows the initial state of the limiting block 2023 to be tilted to one side. When the assembly block 202 is attached to the grid frame 201, the limiting block 2023 will use the restoring elasticity of the torsion spring to allow the abutment block 2024 to abut against the top of the sand core. At the same time, the degree of deflection of the limiting block 2023 can accommodate sand cores of different heights to prevent the sand core from shaking and falling off the placement frame 2 due to buoyancy when it enters the dipping tank 101.
