[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The casting mold with convenient demoulding is provided with a nut, a support rod, a support frame, a hinge shaft, a hinge block, a conveyor belt, a first conveyor wheel, a rocker, a second conveyor wheel and a bottom plate. When the casting liquid is poured into the mold and cooled and needs to be demoulded, it only needs to hold the rocker and shake the turntable. When the turntable rotates, it drives the second conveyor wheel. The second conveyor wheel drives the first conveyor wheel to rotate through the rotation of the conveyor belt. When the first conveyor wheel and the second conveyor wheel rotate, they drive the two-way threaded rod. When the two-way threaded rod rotates, the nut sleeved on the two-way threaded rod will move inward along the thread, so that the support frame hinged on the outside of the nut is lifted upward, so that the support rod is also lifted upward. Because the support rod is hinged on the hinge block by the hinge shaft, when the support rod is lifted upward, it drives the hinge block to be lifted upward. When the hinge block is lifted upward, it will also lift up the bottom plate above the corner block, thereby completing the demoulding of the mold, thereby improving the work efficiency.

[0013] 2. The casting mold that is easy to demold is provided with a lower casting mold box, a connecting shaft, a pulley and a handle. When the casting mold needs to be demolded, the casting mold can be pulled outward by holding the handle. Because the bottom of the lower casting mold box of the casting mold is provided with a connecting shaft and a pulley, the casting mold can be pulled to move when an outward force is applied, thereby reducing a large amount of manpower and material resources.

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a casting mold that is easy to demold, including a lower casting mold box 1, four connecting columns 16 are provided at the bottom of the lower casting mold box 1, and pulleys 17 are provided below the connecting columns 16. By arranging the connecting columns 16 and the pulleys 17, the casting mold can be moved and conveniently taken when needed.

[0020] A pushing device 15 is provided at the bottom of the lower casting mold box 1, and the pushing device 15 is arranged below the bottom plate 14. One end of the two bidirectional threaded rods 1505 is respectively provided with a first transmission wheel 11 and a second transmission wheel 13. The outer sides of the first transmission wheel 11 and the second transmission wheel 13 are sleeved with a conveyor belt 10. A turntable 18 is provided at the front end of the second transmission wheel 13, and the turntable 18 is fixedly connected to the bidirectional threaded rod 1505. The outer side of the turntable 18 is fixedly connected with a rocker arm 12. By arranging the pushing device 15, the turntable 18 and the rocker arm 12, when the rocker arm 12 is rotated, the turntable 18 is driven, and the turntable 18 drives the two bidirectional threaded rods 1505 to rotate through the second transmission wheel 13 and the conveyor belt 10, so as to facilitate the synchronous adjustment of the nuts 1501 on the two bidirectional threaded rods 1505.

[0021] The pushing device 15 includes a bidirectional threaded rod 1505, the bidirectional threaded rod 1505 is externally threadedly connected with a nut 1501, support frames 1503 are provided on both sides of the nut 1501, a pin shaft 1507 is provided between the support frame 1503 and the nut 1501, a support rod 1502 is provided at the top of the support frame 1503, a bottom plate 14 is provided above the support rod 1502, hinge blocks 1506 are fixedly connected to both sides of the bottom of the bottom plate 14, hinge shafts 1504 are provided at the bottom of the two hinge blocks 1506, and the hinge shafts 1504 are hinged at the bottom of the hinge block 1506 and the top of the support rod 1502;

[0022] An upper mold box 8 is disposed above the lower mold box 1, and a casting port 7 is disposed at the top of the upper mold box 8. The number of the casting ports 7 is four.

[0023] The two ends of the lower mold box 1 and the upper mold box 8 are respectively fixedly connected with mounting sleeves 3, and the two ends of the upper mold box 8 and the lower mold box 1 are respectively fixedly connected with opening plates 6, and the upper and lower opening plates 6 are aligned. By providing the opening plates 6, when the casting mold needs to be opened, the upper mold box 8 and the lower mold box 1 can be opened by applying upward and downward forces respectively.

[0024] The inner sleeve of the mounting sleeve 3 is sleeved with the positioning side block 2, the outer wall of the mounting sleeve 3 is provided with a screw 5, and the screw 5 is sleeved in the mounting sleeve 3 and the positioning side block 2, the two mounting sleeves 3 and the positioning side block 2 are aligned up and down, and the middle of the mounting sleeve 3 and the positioning side block 2 is penetrated with a positioning screw 4, and the bottom of the positioning screw 4 is threadedly connected with a nut 19. By providing the positioning side block 2, the mounting sleeve 3, the positioning screw 4, the screw 5 and the nut 19, the mounting sleeve 3 and the positioning side block 2 can be passed through the positioning screw 4, and when the nut 19 moves upward along the positioning screw 4, the upper mold box 8 can be closely fitted with the lower mold box 1.

[0025] The top of the upper casting mold box 8 and the two sides of the lower casting mold box 1 are respectively provided with handles 9, and the handles 9 are designed in a semi-annular shape.

[0026] The working principle of the utility model is as follows: when it is necessary to use a demoulding casting mold, it is only necessary to pull the casting mold outward by holding the handle 9, so that the pulley 17 slides and transfers, and then slowly pour the pouring liquid along the pouring port 7, wait for the casting liquid to cool down before demoulding, and then rotate and open the nut 19 on the positioning screw 4, and then pull the positioning screw 4 out of the mounting sleeve 3, and then open the upper casting mold box 8, and then, hold the rocker 12 and shake the turntable 18, when the turntable 18 rotates, it drives the second transmission wheel 13 to rotate, and the second transmission wheel 13 passes through the conveyor belt 10. The rotation drives the first transmission wheel 11 to rotate. When the first transmission wheel 11 and the second transmission wheel 13 rotate, the bidirectional threaded rod 1505 is driven to move inward. When the bidirectional threaded rod 1505 rotates, the nut 1501 sleeved on the bidirectional threaded rod 1505 will move inward along the thread, so that the support frame 1503 hinged on the outside of the nut 1501 is lifted upward, so that the hinge block 1506 is squeezed upward, pushing the bottom plate 14 above the hinge block 1506, so that the bottom plate 14 slowly rises, so that the casting mold extends out of the lower mold box 1, and the cast casting can be taken out.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
