Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forming molds, in particular to a new type of silicon carbide rod forming mold. Background Technique
[0002] Silicon carbide rods mainly refer to refractory and high-temperature-resistant materials and are used as high-temperature heating elements. When silicon carbide rods are used in hydrogen, the rod bodies will become brittle and the service life will be shortened. Silicon carbide rods will be corroded when contacting with alkali metals, alkalis, silicates, borides, etc., so it is necessary to avoid their contact with the rod bodies. The silicon carbide rod terminal clamp should be in close contact with the aluminum head at the cold end of the rod body. During the use of silicon carbide rods, if fractures or white-hot phenomena are found, new rods should be replaced in time.
[0003] During the forming process of silicon carbide rods, a cutting knife is generally set to cut the silicon carbide rod blank into fixed lengths. During the cutting process of some existing silicon carbide rod forming molds, the extruder is still extruding materials, which may cause the end parts of the silicon carbide rods to be cut unevenly, and subsequent manual leveling is required, affecting production efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the defect that during the cutting process of some existing silicon carbide rod forming molds, the extruder is still extruding materials, which may cause the end parts of the silicon carbide rods to be cut unevenly, and subsequent manual leveling is required, affecting production efficiency, and to provide a new type of silicon carbide rod forming mold.
[0005] The purpose of the utility model is realized through the following technical solutions: a new type of silicon carbide rod forming mold, including a mounting frame, an extruder and a mold are installed on the mounting frame, an electric push rod is installed on the mounting frame, and a cutting knife corresponding to the discharge end of the mold is installed at the telescopic end of the electric push rod. An infrared probe is installed on one side of the mounting frame away from the extruder. The infrared probe is electrically connected to a controller that controls the telescopic movement of the electric push rod, and the infrared probe is electrically connected to a switch that controls the opening and closing of the extruder in the extruder. By setting the infrared probe to be electrically connected to the controller that controls the telescopic movement of the electric push rod and the switch that controls the opening and closing of the extruder in the extruder, it can first control the extruder to stop extruding materials when the infrared probe detects the silicon carbide rod blank, and then the infrared probe controls the electric push rod to push the cutting knife to cut the blank extruded by the mold, so as to effectively avoid the extruder and the mold from still extruding materials during the cutting process of the cutting knife, keep the blank stable during the cutting process, improve the flatness of the cutting by the cutting knife, reduce subsequent leveling processes, and thus improve production efficiency.
[0006] A further technical solution is that an electric sliding table is installed on the mounting frame, and the infrared probe is installed on the moving end of the electric sliding table. By setting the electric sliding table, the infrared probe can be driven to move, so that the infrared probe can sense blanks of different lengths for cutting, and thus silicon carbide rods of different lengths can be produced, improving the practicability of the equipment.
[0007] A further technical solution is that a scale line corresponding to the electric slide table is installed on the mounting frame. By setting the scale line, it is convenient to observe and adjust the length corresponding to the position of the infrared probe, facilitating the observation and operation of personnel.
[0008] A further technical solution is that a conveyor belt is installed below the discharge end of the mold. By setting the conveyor belt, it is convenient to convey the blank, saving manpower.
[0009] A further technical solution is that a rubber soft pad is installed on the conveyor belt. The rubber soft pad is located on the upper part of the conveyor belt. By setting the rubber soft pad, it can protect the blank when the blank falls onto the conveyor belt and protect the appearance of the blank.
[0010] A further technical solution is that the infrared probe is electrically connected to the switch inside the conveyor belt that controls the opening and closing of the conveyor belt. By setting the infrared probe to be electrically connected to the switch inside the conveyor belt that controls the opening and closing of the conveyor belt, when the cutting knife cuts the material, the infrared probe controls the conveyor belt to pause, enabling the conveyor belt to remain stable when the blank is falling.
[0011] A further technical solution is that a friction block corresponding to the cutting knife is installed on the mounting frame. The side of the cutting knife is in contact with the friction block. By setting the friction block, it can rub the cutting knife when the cutting knife cuts and retracts, preventing the cutting knife from adhering to the material and keeping the cutting knife sharp at the same time.
[0012] The utility model has the following advantages: By setting the infrared probe to be electrically connected to the controller that controls the telescopic movement of the electric push rod and the switch inside the extruder that controls the opening and closing of the extruder respectively, when the infrared probe detects the silicon carbide rod blank, it can first control the extruder to stop extruding and discharging, and then the infrared probe controls the electric push rod to push the cutting knife to cut the blank extruded from the mold. Thus, it effectively avoids the situation that the extruder and the mold are still extruding and discharging during the process of the cutting knife cutting the material, keeps the blank stable during the cutting process, improves the flatness of the cutting by the cutting knife, reduces the subsequent trimming process, and thus improves the production efficiency. By setting the electric slide table, it can drive the infrared probe to move, so that the infrared probe can sense blanks of different lengths for cutting, and thus silicon carbide rods of different lengths can be produced, improving the practicability of the equipment.
