[0002] A sand core mold is a casting mold in which a sand core is fixed in a sand mold for casting. Sand mold casting is a common type of casting equipment. In the demolding process of traditional thin-walled sand core molds, due to the large adhesion between the sand core and the mold, a large ejection force or manual knocking is often required, which is inconvenient and reduces work efficiency.

The external controller facilitates the control of the electric telescopic mast, the tilting servo, the vibration motor, and the electric reciprocating push rod.

[0006] Preferably, the top plate is provided with a sliding cylinder at its corner, and the bottom mold is connected to a guide post at each corner of its top, with the guide post slidably connected to the sliding cylinder.

[0007] Preferably, the rubber outer frame is connected to the outer surface of the bottom mold, and several vibration motors are equidistantly distributed, with the vibration motors used to vibrate the bottom mold for auxiliary demolding.

The flipping servo motor is then activated to rotate and indirectly invert the bottom and top molds. The electric reciprocating push rod continuously pushes and pulls the horizontal plate, and the impact blocks on the surface of the horizontal plate continuously strike the bottom plate, thereby striking the sand core inside the bottom mold. At the same time, several vibration motors are activated to continuously vibrate the bottom mold.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a thin-walled sand core mold with a quick demolding structure, including a base plate 1, a bottom mold 2 connected to the top of the base plate 1, a top mold 3 matching the bottom mold 2 covering the top of the bottom mold 2, a top plate 4 connected to the top of the top mold 3, a first sand core cavity 13 in the middle of the bottom mold 2, a second sand core cavity 14 matching the first sand core cavity 13 in the middle of the top mold 3, a rubber outer frame 7 connected to the outer side of the bottom mold 2, a plurality of vibration motors 8 embedded in the middle of the rubber outer frame 7, a bottom frame 9 connected to the bottom of the base plate 1, and electric reciprocating push rods 23 installed on both sides of the bottom frame 9. The output end of 3 is connected to a horizontal plate 24. The top of the horizontal plate 24 is provided with several impact blocks 25. The bottom mold 2 is provided with a positioning plate 10 on one side. The positioning plate 10 is provided with a round shell 11 on one side. An electric telescopic rod 16 is installed inside the round shell 11. The output end of the electric telescopic rod 16 is connected to a moving plate 17. A tilting servo motor 18 is installed on one side of the moving plate 17. The output end of the tilting servo motor 18 is connected to a rotating rod 19. One end of the rotating rod 19 is connected to the positioning plate 10. The side of the positioning plate 10 away from the rotating rod 19 is connected to a positioning pin 20. The top plate 4 and the bottom plate 1 are both provided with a positioning pin 20 that matches the positioning pin 20.

[0020] In this embodiment, the round shell 11 is connected to the external molding equipment through the mounting plate 12, the top mold 3 and the bottom mold 2 are closed, and the sand core is formed through the first sand core mold cavity 13 and the second sand core mold cavity 14.

[0021] See Figure 1-4 The electric telescopic rod 16, the tilting servo motor 18, the vibration motor 8 and the electric reciprocating push rod 23 are all electrically connected to an external power supply through an external controller. The top plate 4 is provided with a sliding cylinder 6 at its corners, and the bottom mold 2 is connected with a guide post 5 at its top corners. The guide post 5 is slidably connected to the sliding cylinder 6.

[0022] In this embodiment, during demolding, the electric telescopic rod 16 is activated to push the moving plate 17, the flipping servo motor 18, the rotating rod 19, and the positioning plate 10 to move, so that the positioning pin 20 is inserted into the positioning slot 15 of the top plate 4 and the bottom plate 1. Then, the flipping servo motor 18 is activated to rotate the positioning plate 10, which indirectly turns the bottom mold 2 and the top mold 3 upside down. The sand core inside the bottom mold 2 will fall under the action of gravity, which is conducive to the demolding of the sand core.

[0023] See Figure 1-4 The rubber outer frame 7 is connected to the outer surface of the bottom mold 2. Several vibrating motors 8 are equidistantly distributed. The horizontal plate 24 corresponds to the bottom of the bottom plate 1. Several impact blocks 25 are equidistantly distributed. The side of the round shell 11 away from the positioning plate 10 is connected to the mounting plate 12. The surface of the mounting plate 12 is provided with fixing screw holes. The positioning pin 20 and the positioning slot 15 are engaged. The top and bottom of the moving plate 17 are both connected to the slider 21. The inner walls of the round shell 11 are provided with sliding grooves 22 that match the slider 21. The sliding grooves 22 and the slider 21 are slidably connected.

[0024] In this embodiment, the electric reciprocating push rod 23 can continuously push and pull the horizontal plate 24, and the impact block 25 on the surface of the horizontal plate 24 can continuously strike the bottom plate 1, thereby striking the sand core inside the bottom mold 2. At the same time, several vibration motors 8 can continuously vibrate the bottom mold 2, thereby accelerating the sand core from the middle of the first sand core cavity 13 of the bottom mold 2 through striking and vibration.

[0025] In practical use, this utility model provides a thin-walled sand core mold with a quick demolding structure. The cylindrical shell 11 is connected to an external molding device via a mounting plate 12. The top mold 3 and bottom mold 2 are closed. The sand core is formed through the first sand core mold cavity 13 and the second sand core mold cavity 14. During demolding, the electric telescopic rod 16 is activated to push the moving plate 17, the tilting servo motor 18, the rotating rod 19, and the positioning plate 10 to move, inserting the positioning pins 20 into the positioning slots 15 of the top plate 4 and the bottom plate 1. Then, the tilting servo motor 18 is activated to rotate the positioning plate 10, indirectly inverting the bottom mold 2 and the top mold 3. The sand core inside the bottom mold 2 will fall under gravity, allowing the mold to release its contents. The electric reciprocating push rod 23 can continuously push and pull the horizontal plate 24. The impact block 25 on the surface of the horizontal plate 24 can continuously strike the bottom plate 1, and then strike the sand core inside the bottom mold 2. At the same time, several vibration motors 8 can continuously vibrate the bottom mold 2. Through inversion, striking and vibration, the sand core can be accelerated to come out from the middle of the first sand core mold cavity 13 of the bottom mold 2. Then, the positioning plate 10 is pulled back so that the positioning pin 20 is no longer stuck in the positioning slot 15. Then the top mold 3 is opened directly, and the sand core can be directly detached from the bottom mold 2. The entire sand core mold is convenient and quick to demold, without the need for repeated manual knocking demolding, which improves the demolding processing efficiency.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
