Description

Technical Field

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

[0002] When manually casting using a mold, workers pour molten metal into the mold through a pouring port. The metal cools and takes shape within the mold, controlled by the upper and lower dies. The worker removes the formed part from the mold, completing the casting process.

[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 easier for workers to perform casting and demoulding work. Summary of the Invention

[0005] The purpose of the present invention is to propose a casting demoulding device in order to solve the above problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A casting demoulding device, comprising:

[0008] A base, wherein a convex block protrudes from the base and a slot is provided on the convex block, the convex block engages with the sleeve slot at the bottom of the lower mold, and a block engaging with the sleeve slot is fixed in the sleeve slot;

[0009] The upper mold, the lower mold and the upper mold form a complete mold, and the upper mold is provided with a casting port and air holes;

[0010] The bracket is rotatably connected to the base, and a slide groove is provided on the bracket. A slide rod is slidably connected to the slide groove, and a connecting rod is fixed on the slide rod. A handle is fixed on the top of the connecting rod. The connecting rod connects the upper mold and the lower mold through a connecting piece.

[0011] The side block is fixed on the base and provided with a matching piece. The matching piece cooperates with the connecting piece to assist in separating the formed metal parts from the lower mold and the upper mold.

[0012] Preferably, the connecting part includes a round block fixed on the connecting rod, a rotating ring rotatably connected to the upper mold, and a circular groove adapted to the round block is provided on the rotating ring, a spring is sleeved on the sliding rod, a spherical block is fixed on the side wall of the connecting rod, and the spherical block cooperates with the mating part to separate the outer wall of the metal part from the inner wall of the lower mold and the upper mold.

[0013] Preferably, one end of the spring is fixed to the connecting rod, and the other end is fixedly connected to the bracket, and the spring pushes the connecting rod downward so that the connecting rod presses the upper mold and the lower mold into contact, and the bracket controls its angle on the base through a limit piece.

[0014] Preferably, the mating part includes a cross bar slidably connected to the side block, and a push block is fixed on the cross bar, a knocking rod and an arc block are fixed on the push block, and a spring 2 is sleeved on the cross bar, and one end of the spring 2 abuts against the push block, and the other end abuts against the side block.

[0015] Preferably, a transverse groove is provided on the base, and a bottom block slidably connected to the transverse groove is fixed to the bottom of the push block, and the transverse rod is connected to a round sleeve through a thread, and a stop block is fixed on the round sleeve.

[0016] Preferably, after the lower mold is separated from the base, spring 2 pushes the push block to move closer to the center of the base until the bottom block abuts against the inner wall of the horizontal groove. At this time, the cross bar is separated from the side block, and the cross bar and the push block can be lifted up and separated from the base.

[0017] Preferably, the limiting member includes opening one and opening two on the base, and a corresponding hole corresponding to opening one or opening two is provided on the bracket. A magnetic rod passes through the opening one, and when the end of the magnetic rod is inserted into the corresponding hole, the bracket is located directly above the base. When the magnetic rod passes through the opening two and extends into the corresponding hole, the side wall of the bracket and the base are in contact with the ground together, and the end of the magnetic rod is inserted into the corresponding hole and fixed to the bracket by magnetic force.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this application, as the connecting rod continues to rotate, when the spherical block is not in contact with the arc block, the knocking rod moves with the push block under the elastic force of spring 2 until the knocking rod collides with the lower die. The continuous rotation of the connecting rod causes the knocking rod to continuously and intermittently knock on the lower die, thereby causing the metal parts in the lower die to separate from the lower die, making it easier to remove the metal parts from the lower die later, which is more convenient.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figures 1-6 , the present invention provides a technical solution:

[0031] A casting demoulding device, comprising:

[0032] A base 1, with a protruding block 2 protruding from the base 1 and a slot 3 formed on the protruding block 2, the protruding block 2 engages with a sleeve slot 5 at the bottom of the lower mold 4, and a block 6 engaging with the slot 3 is fixed in the sleeve slot 5;

[0033] 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 referenced from the prior art and are not described in detail here.

[0034] 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. The connecting rod 16 connects the upper mold 7 and the lower mold 4 through a connecting piece.

[0035] The side block 20 is fixed on the base 1 and provided with a matching piece. The matching piece cooperates with the connecting piece to assist in separating the formed metal parts from the lower mold 4 and the upper mold 7.

[0036] Specifically, such as Figure 1 As shown, the connector includes a connecting rod 16 with a round block 18 fixed to it, a rotating ring 10 rotatably connected to the upper mold 7, and a circular groove 11 formed on the rotating ring 10 that matches the round block 18. A spring 17 is mounted on the slide rod 14, and a spherical block 19 is fixed to the side wall of the connecting rod 16. The spherical block 19 cooperates with the mating piece to separate the outer wall of the metal part from the inner walls of the lower mold 4 and the upper mold 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. The spring 17 pushes the connecting rod 16 downward, so that the connecting rod 16 presses the upper mold 7 and the lower mold 4 into contact. The bracket 12 controls its angle on the base 1 through a limiter. Under the elastic force of spring 17, connecting rod 16 moves downward, causing round block 18 on connecting rod 16 to engage with round groove 11 on rotating ring 10. Under the elastic force of spring 17, connecting rod 16 presses upper mold 7 into contact with lower mold 4. At this time, molten metal can be added to the mold through casting gate 8, facilitating the molding of metal parts in the mold.

[0037] Specifically, such as Figure 3 As shown, the mating parts include a crossbar 22 slidably connected to the side block 20, and a push block 23 fixed to the crossbar 22. A knock rod 26 and an arc block 27 are fixed to the push block 23. A spring 25 is sleeved on the crossbar 22, with one end of the spring 25 abutting the push block 23 and the other end abutting the side block 20. A transverse groove 21 is formed on the base 1, and a bottom block 24 slidably connected to the transverse groove 21 is fixed to the bottom of the push block 23. A circular sleeve 28 is threadedly connected to the crossbar 22, and a stop block 29 is fixed to the circular sleeve 28. After the lower mold 4 is separated from the base 1, the spring 25 pushes the push block 23 to move closer to the center of the base 1 until the bottom block 24 abuts the inner wall of the transverse groove 21. At this time, the crossbar 22 is separated from the side block 20, and the crossbar 22 and the push block 23 can be lifted up and separated from the base 1.

[0038] 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 moves 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 strikes the lower die 4, separating the parts inside the lower die 4 from the lower die 4.

[0039] Specifically, such as Figure 3 As shown, the limiting member includes an opening 1 30 and an opening 2 31 on the base 1, and a corresponding hole 32 corresponding to the opening 1 30 or the opening 2 31 is provided 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. 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 together, and the end of the magnetic rod 33 extends into the corresponding hole 32, and is fixed to the bracket 12 by magnetic force.

[0040] 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 arbitrarily on the base 1 under force and increasing the risk of damage.

[0041] In summary, this embodiment provides a method of lifting connecting rod 16 via handle 15, moving it away from base 1. Slot 5 of lower die 4 engages with protrusion 2 on base 1, and block 6 within slot 5 engages with slot 3, allowing upper die 7 and lower die 4 to dock. When handle 15 is released, connecting rod 16 moves downward under the elastic force of spring 17 until round block 18 on connecting rod 16 engages with round groove 11 on rotating ring 10. With the cooperation of connecting rod 16, upper die 7 and lower die 4 are stably connected.

[0042] The molten metal is poured into the mold formed by the upper mold 7 and the lower mold 4 through the casting port 8. With the cooperation of the air holes 9, the metal parts can be formed in the mold.

[0043] After the metal parts in the mold are formed, the connecting rod 16 can be rotated by the handle 15, causing the spherical block 19 to contact the arc block 27 during rotation, pushing the push block 23 to move, compressing the spring 25, and at this time the knocking rod 26 is separated from the lower mold 4.

[0044] 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 second spring 25 until the knocking rod 26 collides with the lower die 4 .

[0045] 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.

[0046] The above description of the embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily 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 is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
