Description

Technical Field

[0001] This application mainly relates to the field of melting machine equipment, and in particular to a mold device for a high-frequency induction heating device and a high-frequency induction heating device. Background Technology

[0002] High-frequency induction heating sample preparation equipment is widely used as a sample pretreatment device for X-ray fluorescence spectroscopy analysis because of its fast heating speed and short preparation time for glass flakes.

[0003] The working principle of high-frequency induction heating equipment is to place the crucible containing the sample inside the induction coil, thereby heating and melting the sample; in order to pour the molten sample in the crucible into the mold to form a molten sheet, the induction coil is installed on a rotating mechanism. The rotating mechanism drives the coil to rotate at a certain angle, thereby pouring the sample in the molten sample crucible into the mold crucible.

[0004] While traditional high-frequency induction heating melting equipment offers fast heating speeds and short glass sheet production times, it also presents several significant challenges. For instance, the melting machine disclosed in Chinese Patent ZL202420201417.3, along with other traditional melting equipment solutions, essentially involves directly introducing the molten metal into the mold crucible during the casting process. This results in inconsistent pouring speeds, making precise control difficult. Pouring too quickly can prevent gas from escaping from the bottom of the mold crucible, contaminating the sample and affecting the molding quality. Furthermore, temperature differences within the heated areas of the mold crucible lead to variations in the fluidity of the molten metal in contact with the surface. Some of the molten metal solidifies prematurely while remaining liquid, generating internal stress during the casting process and increasing the risk of cracking defects. Utility Model Content

[0072] The mold device in this application mainly involves three parts: the mold crucible assembly, the rotation mechanism, and the lifting mechanism.

[0073] Mold and crucible assembly

[0074] It mainly consists of a ceramic support cylinder, a mold crucible, and a mold coil (heating coil); the mold crucible is supported on the ceramic support cylinder, and the mold coil is wrapped around the outer circumference of the ceramic support cylinder.

[0075] Lifting mechanism section

[0076] The main moving parts consist of gears (2), miniature slide rails, and racks, driven by a motor (5); the base plate and sliding plate are supporting components; the support plate mounted on the sliding plate serves as the support plate for the rotary mechanism; the photoelectric sensor and the triggering plate serve as the position feedback unit for the lifting mechanism.

[0077] The sliding plate is mounted on two slide rails (6), and the rack is mounted on the sliding plate and meshes with the gear (2) as the main moving component.

[0078] Slewing mechanism section

[0079] The main moving parts consist of gear 3 (19), gear (12), ceramic bearing, and support shaft, and are driven by motor (2). Motor (2) is mounted on the lower mounting plate, which is fixed on the support plate; gear 3 (19) is mounted on the output shaft of motor (2), and gear 3 (19) meshes with gear (12); gear (12) and support shaft (11) are fixed by screws; the outer ring of ceramic bearing (18) is tightly fitted with support plate (4), ceramic bearing (18) is installed in support plate (4), and the inner ring of ceramic bearing (18) is fitted with support shaft (11); ceramic support cylinder (2) is placed in support shaft (4), and the mold crucible (3) is supported on the ceramic support cylinder.

[0080] Figure 1The image shows the ejected state of the mold crucible, where the mold crucible is detached from the mold coil to prevent eddy current heating in the mold coil. Figure 2 The mold crucible is in a retracted state, located inside the mold coil, to preheat the mold crucible.

[0081] The high-frequency induction device starts sample preparation. In the initial state, the mold crucible 3 is located outside the mold coil 1. The mold crucible is pushed out from the mold coil shown in the figure. Figure 1 When heating begins, the lifting mechanism sends the mold crucible 3 into the coil 1. Figure 2 The mold crucible retracts into the mold coil and is induction heated in a changing eddy current field. When the molten liquid is poured into the mold crucible, the molten liquid is poured into the mold crucible by means of the rotation of the rotary mechanism. The molten liquid rotates with the mold crucible, which plays the role of automatic leveling and air venting until it cools and forms. Then the lifting mechanism pushes out the mold crucible again.
