Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a casting mold for forming an elevator roller casting. Background Art

[0002] Elevator rollers (also often called elevator guide wheels, elevator door rollers or elevator pulleys) are very important components in the elevator system. Their main function is to guide the movement of the elevator door, bear the weight of the elevator door, and ensure the smooth and safe operation of the elevator.

[0003] The elevator roller casting molding casting mold usually adopts sand casting, die casting or other casting processes to manufacture roller parts. Due to the high temperature of the casting liquid, after the mold is poured, personnel are required to complete the demoulding. They will wear heat-insulating gloves to pry open the upper mold to complete the casting. However, the efficiency of personnel opening the mold is not high, and if the operation is improper, personnel may be easily burned.

[0004] In order to solve the above problems, we propose an elevator roller casting forming casting mold. Utility Model Content

The cam is fixedly connected with an extension plate, and the outer side wall of the upper mold is fixedly connected with two fixing plates 2, and the outer side wall of the lower mold is fixedly connected with two fixing plates 1, and the fixing plate 1 is provided with a threaded hole 1, and the fixing plate 2 is threadedly provided with a fastening bolt. The top of the casting machine body is fixedly connected with a support plate 1, and the support plate 1 is provided with an opening. The inner side of the support plate 1 is provided with a pushing bolt, and the opening is provided with a thread, and the pushing bolt contacts the inner thread of the opening. The upper mold is provided with a threaded hole 2, and the right side wall of the pushing bolt is rotatably connected with a push plate, and the push plate slides through the upper mold, and the right side wall of the push plate is fixedly connected with a sealing plate.

[0008] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: the upper mold and the lower mold are equal in size, and multiple limit rods are evenly arranged at the four corners of the top of the pouring machine body. The two fixed plates are located on the front and back sides of the upper mold, and the two fixed plates are located on the front and back sides of the lower mold. The tops of multiple limit rods are fixedly connected with baffles.

[0009] In order to better achieve the above purpose, the present invention adopts a further technical solution: the second support plate is located on the right side of the lower mold, and the cam is located directly below the extension plate.

[0010] In order to better achieve the above purpose, the present invention adopts a further technical solution: the support plate 1 is located on the left side of the lower mold.

[0011] In order to better achieve the above purpose, the present invention adopts a further technical solution: the push plate contacts the inner wall of the upper mold, and the size of the push plate is larger than the size of the mold inlet.

[0012] The advantages of the utility model are: the cam is driven to rotate by the motor, and when the convex point of the cam contacts the bottom of the extension plate, the upper mold is driven to move through the extension plate, and the upper mold moves vertically upward along the limit rod. The baffle can limit the movement of the upper mold. When the upper mold moves upward and does not contact the lower mold, the casting can be taken out, reducing the mold opening time. When taking out the casting, the personnel can stay away from the pouring machine body for a distance, and will not cause harm to the personnel. BRIEF DESCRIPTION OF THE DRAWINGS
