[0024] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 4 The demoulding machine for metal casting includes a support plate 1, a mold body 2 is provided on the support plate 1, and knocking plates 4 are movably abutted on the four sides of the mold body 2. Mounting frames 3 are symmetrically arranged on the support plate 1, and rotating rods 6 are rotatably connected between the mounting frames 3. Two adjacent rotating rods 6 are connected by a transmission module, and the rotating rods 6 are connected to the knocking plates 4 through a connecting rod 5. A swing component is provided between the mounting frame 3 and the rotating rod 6, and a driving component movably connected to the swing component is provided on the support plate 1.

[0025] In this embodiment, the driving assembly drives the rotating rod 6 to swing back and forth through the swing assembly, and the rotating rod 6 drives the knocking plate 4 to rotate synchronously through the connecting rod 5. The knocking plate 4 knocks back and forth on the outer wall of the mold body 2 by reciprocating swinging, which is convenient for separating the support plate 1 and the product. It has the effects of reciprocating swing, efficient knocking, fast demoulding and simple and practical operation, wherein the length of the knocking plate 4 is consistent with the length of the mold body 2.

[0026] In one embodiment of the present invention, see Figure 1 and Figure 3 The transmission module includes a bevel gear 18 and a bevel gear 19 meshing with each other. The bevel gear 18 and the bevel gear 19 are respectively arranged at two ends of the rotating rod 6 close to each other.

[0027] In this embodiment, the driving assembly drives the rotating rod 6 to rotate reciprocatingly through the swinging assembly, and the rotating rod 6 drives the bevel gear 18 at one end to rotate synchronously. The bevel gear 18 drives the adjacent rotating rod 6 to rotate synchronously by meshing with the bevel gear 2 19, thereby realizing the synchronous rotation of the knocking plate 4 located around the support plate 1, which is convenient for knocking the outer wall of the mold body 2 at the same time, thereby improving the demolding efficiency.

[0028] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 4 The swing assembly includes a gear portion 7, which is arranged on the outside of the rotating rod 6. A slide plate 9 is slidably provided on the mounting frame 3, and a rack portion 8 meshing with the gear portion 7 is provided on the slide plate 9. A push plate 12 is provided at one end of the slide plate 9 close to the mold body 2. An abutment cylinder 13 is movably provided between the mold body 2 and the mounting frame 3. The push plate 12 is slidably matched with the inner wall of the abutment cylinder 13, and a spring 14 is connected between the push plate 12 and the abutment cylinder 13.

[0029] In this embodiment, in the initial state, the knocking plate 4 is in contact with the outer wall of the mold body 2, the first tooth of the rack part 8 close to the mold body 2 is meshed with the tooth of the gear part 7, the spring 14 is at its original length, and the driving component pushes the slide plate 9 to approach the mold body 2, and the slide plate 9 drives the rack part 8 to move synchronously, and the rack part 8 drives the rotating rod 6 to rotate counterclockwise by meshing with the gear part 7, and the rotating rod 6 drives the knocking plate 4 to rotate synchronously through the connecting rod 5, so that the knocking plate 4 is away from the mold body 2. At the same time, the slide plate 9 drives the push plate 12 to approach the mold body 2, and the spring 14 is stressed and contracts. When the driving component is away from the slide plate 9, the spring 14 extends and The slide plate 9 is pushed away from the mold body 2 by the push plate 12, and the slide plate 9 drives the rack part 8 to move synchronously. The rack part 8 drives the rotating rod 6 to rotate clockwise by meshing with the gear part 7. The rotating rod 6 drives the knocking plate 4 to rotate synchronously through the connecting rod 5. The knocking plate 4 knocks on the outer wall of the mold body 2 by rotating clockwise, which can separate the mold body 2 and the product and facilitate demoulding. The slide plate 9 is provided with a through groove 10, and a guide plate 11 connected to the mounting frame 3 is slidably provided in the through groove 10. The sliding of the slide plate 9 can be stably guided by the sliding cooperation between the guide plate 11 and the through groove 10.

[0030] In one embodiment of the present invention, see Figure 1 and Figure 2 The driving assembly includes an abutment plate 15 arranged at the bottom of the slide plate 9, and a cam 16 rotatably abutted with the abutment plate 15 is rotatably provided on the support plate 1, and the cam 16 is connected to a rotating motor 17 arranged on the support plate 1.

[0031] In this embodiment, in the initial state, the knocking plate 4 is in contact with the outer wall of the mold body 2, and the nearest end of the cam 16 is in contact with the abutment plate 15. When the product needs to be demolded, the rotating motor 17 drives the cam 16 to rotate. In the process of the farthest end of the cam 16 approaching the abutment plate 15, the knocking plate 4 is away from the mold body 2, and the spring 14 is stressed and contracts. In the process of the farthest end of the cam 16 moving away from the abutment plate 15, the spring 14 restores its original length, and the knocking plate 4 approaches the mold body 2, so that the knocking plate 4 can be knocked once. Through the continuous rotation of the cam 16, the reciprocating knocking of the knocking plate 4 can be achieved, which is convenient for the rapid demolding of the mold body 2 and the product.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
