[0030] The scraper mechanism 7 is arranged on the top surface of the working plate 1 and is used to scrape off the excess material on the top surface of the supporting mold 3. The scraper mechanism 7 includes two fixed plates 71 fixed on the top surface of the working plate 1 and symmetrical to each other, two rotating columns 72 rotatably connected to the fixed plates 71 on the same side, a screw 73 coaxially fixed between the two rotating columns 72, a moving rod 74 threadedly connected to the screw 73 and in an L-shaped shape, a scraper 75 fixed on the rear side surface of the cross rod end of the moving rod 74 and used to scrape off the excess material on the top surface of the upper mold body 32, a rotating rod 77 coaxially fixed on the side surface of one of the rotating columns 72 away from the screw 73, two gears 78 located above the working plate 1 and used to drive the rotating rod 77 to rotate, and a rotating rod 77 installed on the side surface of one of the fixed plates 71 away from the screw 73 and used to drive the two gears The motor 79 rotates the wheel 78, and the moving rod 74 is slidably connected to the top surface of the working plate 1, and the two gears 78 are meshed with each other. The casting of the triangular saddle can be carried out by setting the working plate 1, the supporting mold 3, the upper mold body 32 and the lost mold body 5.

[0034] Furthermore, the scraper 75 corresponds to the position and size of the upper mold body 32, and the bottom surface of the scraper 75 is tightly fitted with the top surface of the upper mold body 32, so that the scraper 75 can smoothly scrape off excess material on the top surface of the upper mold body 32.

Through the coordinated use of the frame 2 and the lifting mechanism 4, the demolding work of the triangular saddle can be carried out smoothly.

[0036] It is worth noting that the longitudinal cross-sectional shape of the guide groove on the top surface of the working plate 1 is I-shaped, and the shape of the guide block 76 is I-shaped that matches the shape of the guide groove on the top surface of the working plate 1, which can make the connection between the guide block 76 and the guide groove on the top surface of the working plate 1 tighter, and indirectly make the scraper 75 more stable during movement.

[0037] It is worth noting that an anti-skid plate 9 matching its shape is fixed to the bottom end of the support plate 8, and the thickness of the anti-skid plate 9 is 2-6 cm, preferably 4 cm in this article, so as to increase the friction between the entire device and the ground, thereby making the entire device more stable during operation.

[0038] It is worth emphasizing that the lifting mechanism 4 also includes a protective tube 43 fixed on the bottom surface of the horizontal plate end of the frame body 2, the cylinder body of the electric cylinder 41 is located inside the protective tube 43, and the piston rod of the electric cylinder 41 passes through the bottom surface of the protective tube 43. The scraper mechanism 7 also includes a protective box 711 fixed on the surface of one of the fixed plates 71 away from the screw 73. The motor 79 is located inside the protective box 711, and the rotating shaft 710 passes through the surface of the protective box 711 away from the screw 73. It can protect the electric cylinder 41 and the motor 79, thereby extending the service life of the electric cylinder 41 and the motor 79.

[0039] Finally, it should be noted that the electric cylinder 41, motor 79 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0040] In the specific use of this embodiment, when casting work is required, the material is first cast through an external casting device. After the lost foam body 5 is filled with material, a part of the excess material will adhere to the top surface of the upper mold body 32. Then, the output shaft of the motor 79 is started and controlled by the external PLC to rotate alternately in positive and negative directions. The rotation of the output shaft of the motor 79 drives the rotating shaft 710 coaxially connected thereto to rotate. The rotation of the rotating shaft 710 drives the same-side gear 78 coaxially fixed thereto to rotate. The rotation of the gear 78 drives another gear 78 meshing therewith to rotate. The rotation of the other gear 78 drives the rotating rod 77 coaxially fixed thereto to rotate. The rotation of the rotating rod 77 drives the same-side rotating column 72 coaxially fixed thereto to rotate. The rotating column 72 The rotation drives the screw rod 73 coaxially fixed thereto to rotate, and the rotation of the screw rod 73 drives the moving rod 74 threadedly connected thereto to move. The moving rod 74 moves under the guidance of the guide block 76 and the guide groove on the top surface of the working plate 1. Because the output shaft of the motor 79 rotates alternately forward and reverse, the screw rod 73 is driven to rotate alternately forward and reverse, thereby driving the moving rod 74 to reciprocate in the left and right directions. The movement of the moving rod 74 drives the scraper 75 fixed thereto to reciprocate left and right. The scraper 75 can scrape off the excess material on the top surface of the upper mold body 32 during the reciprocating movement. When the scraper 75 is scraped for a period of time and is located at a suitable position on the left or right side of the upper mold body 32, the motor 79 is turned off through the external PLC.

[0041] When the triangular saddle is cooled and formed, the electric cylinder 41 is started through the external PLC, and the piston rod of the electric cylinder 41 contracts, so that the piston rod of the electric cylinder 41 moves upward. The movement of the piston rod of the electric cylinder 41 drives the upper mold body 32 fixed to it by the gasket 42 to move upward. When the upper mold body 32 moves to a suitable height position, the electric cylinder 41 is closed through the external PLC, thereby completing the demolding work.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
