[0001] The invention relates to the technical field of casting, in particular to a casting demoulding device. Background Art

[0002] When using a mold for casting, workers need to pour the molten metal into the mold through the pouring port on the mold. Under the action of the upper and lower molds, the metal in the mold can be formed after cooling. The worker takes the formed parts out of the mold to complete the casting operation.

[0003] However, since there will be a certain degree of adhesion between the metal and the mold after cooling, the metal cannot be quickly and conveniently demolded from the mold after forming. At this time, the staff needs to use tools to knock on the mold to separate the formed metal parts from the mold, which is more cumbersome.

[0004] Therefore, the traditional casting can be improved to make it convenient for the workers to carry out the casting and demoulding work. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 6 , the present invention provides a technical solution: A casting demoulding device, comprising: A base 1, a convex block 2 protrudes from the base 1, and a slot 3 is formed on the convex block 2, the convex block 2 is engaged with a sleeve slot 5 at the bottom of a lower mold 4, and a block 6 engaged with the sleeve slot 3 is fixed in the sleeve slot 5; The upper mold 7, the lower mold 4 and the upper mold 7 form a complete mold, and the upper mold 7 is provided with a casting port 8 and an air hole 9. The upper mold 7, the lower mold 4, the casting port 8 and the air hole 9 are directly cited from the prior art and are not described in detail here. The bracket 12 is rotatably connected to the base 1, and a slide groove 13 is provided on the bracket 12, a slide rod 14 is slidably connected to the slide groove 13, and a connecting rod 16 is fixed to the slide rod 14, a handle 15 is fixed to the top of the connecting rod 16, and the connecting rod 16 connects the upper mold 7 with the lower mold 4 through a connecting piece; The side block 20 is fixed on the base 1 and provided with a matching piece, which cooperates with the connecting piece to assist in separating the formed metal parts from the lower mold 4 and the upper mold 7.

[0018] Specifically, Figure 1 As shown, the connecting member includes a connecting rod 16 with a round block 18 fixed thereon, a rotating ring 10 rotatably connected to the upper die 7, and a round groove 11 adapted to the round block 18 is provided on the rotating ring 10, a spring 17 is sleeved on the slide bar 14, a spherical block 19 is fixed on the side wall of the connecting rod 16, and the spherical block 19 cooperates with the matching piece, so that the outer wall of the metal part is separated from the inner wall of the lower die 4 and the upper die 7. One end of the spring 17 is fixed to the connecting rod 16, and the other end is fixedly connected to the bracket 12, and the spring 17 pushes the connecting rod 16 downward, so that the connecting rod 16 presses the upper die 7 to abut against the lower die 4, and the bracket 12 controls its angle on the base 1 through the limiter. Under the elastic force of spring 17, the connecting rod 16 can move downward, so that the round block 18 on the connecting rod 16 is engaged with the round groove 11 provided on the rotating ring 10, and under the elastic force of spring 17, the connecting rod 16 presses the upper mold 7 to abut against the lower mold 4. At this time, molten metal can be added into the mold through the casting port 8, so that the metal parts can be formed in the mold.

[0019] Specifically, Figure 3 As shown, the matching part includes a cross bar 22 slidably connected to the side block 20, and a push block 23 is fixed on the cross bar 22, a knocking rod 26 and an arc block 27 are fixed on the push block 23, and a spring 25 is sleeved on the cross bar 22, and one end of the spring 25 abuts against the push block 23, and the other end abuts against the side block 20. A transverse groove 21 is provided on the base 1, and a bottom block 24 slidably connected to the transverse groove 21 is fixed at the bottom of the push block 23, and the cross bar 22 is connected to a round sleeve 28 by threading, and a block 29 is fixed on the round sleeve 28. After the lower mold 4 is separated from the base 1, the spring 25 pushes the push block 23 to move close to the center of the circle of the base 1 until the bottom block 24 abuts against the inner side wall of the transverse groove 21, and the cross bar 22 is separated from the side block 20 at this time, and the cross bar 22 and the push block 23 can be lifted up and separated from the base 1.

[0020] Under the elastic force of the second spring 25, the knocking rod 26 can be brought into contact with the lower die 4. As the connecting rod 16 rotates, the spherical block 19 collides with the arc block 27, thereby pushing the arc block 27 and the push block 23 to move together, compressing the second spring 25. At this time, the knocking rod 26 is away from the lower die 4. As the connecting rod 16 continues to rotate, the spherical block 19 is away from the arc block 27. Under the elastic force of the second spring 25, the push block 23 moves until the knocking rod 26 knocks on the lower die 4, so that the parts in the lower die 4 are separated from the lower die 4.

[0021] Specifically, Figure 3As shown, the limiting member includes an opening 1 30 and an opening 2 31 formed on the base 1, a corresponding hole 32 corresponding to the opening 1 30 or the opening 2 31 is formed on the bracket 12, a magnetic rod 33 passes through the opening 1 30, and when the end of the magnetic rod 33 extends into the corresponding hole 32, the bracket 12 is located directly above the base 1 at this time, and when the magnetic rod 33 passes through the opening 2 31 and extends into the corresponding hole 32, the side wall of the bracket 12 and the base 1 are in contact with the ground at this time, and the end of the magnetic rod 33 extends into the corresponding hole 32, and is fixed to the bracket 12 by magnetic force.

[0022] With the cooperation of the magnetic rod 33 , the position of the bracket 12 can be fixed when the device is idle or transported, preventing the bracket 12 from rotating on the base 1 at will due to force, thereby increasing the risk of damage.

[0023] In summary, the present embodiment provides a method of lifting the connecting rod 16 by means of the handle 15, so that the connecting rod 16 is away from the base 1. The sleeve groove 5 of the lower mold 4 is engaged with the protrusion 2 on the base 1, and the block 6 in the sleeve groove 5 is engaged with the slot 3, and the upper mold 7 and the lower mold 4 can be docked at this time. The lifting of the handle 15 is released, and the connecting rod 16 moves downward under the elastic force of the spring 17 until the round block 18 on the connecting rod 16 is engaged with the round groove 11 provided on the rotating ring 10. With the cooperation of the connecting rod 16, the upper mold 7 and the lower mold 4 are stably connected.

[0024] The molten metal is poured into the mold formed by the upper mold 7 and the lower mold 4 through the casting port 8, and with the cooperation of the air holes 9, the metal parts can be formed in the mold.

[0025] After the metal parts in the mold are formed, the connecting rod 16 can be rotated by the handle 15, so that the spherical block 19 contacts the arc block 27 during rotation, pushing the push block 23 to move and compress the spring 25. At this time, the knocking rod 26 is separated from the lower mold 4.

[0026] As the connecting rod 16 continues to rotate, when the spherical block 19 is no longer in contact with the arc block 27 , the knocking rod 26 moves along with the push block 23 under the elastic force of the spring 25 until the knocking rod 26 collides with the lower die 4 .

[0027] The continuous rotation of the connecting rod 16 causes the knocking rod 26 to continuously and intermittently knock the lower mold 4, thereby causing the metal parts in the lower mold 4 to separate from the lower mold 4. The staff lifts the connecting rod 16 upward by the handle 15, and then removes the upper mold 7, and then can more conveniently remove the parts from the lower mold 4.

[0028] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
