Description

Technical Field

[0001] This utility model specifically relates to the technical field of graphite mold heating devices, and more specifically to a graphite mold heating and temperature equalization device. Background Technology

[0002] Graphite molds have important applications in many fields, such as molds for manufacturing chips in semiconductor manufacturing, smelting crucibles in rare metal production, and fixing and conducting heat in high-temperature welding. This is because graphite has a series of excellent properties, such as high strength, high wear resistance, and excellent high-temperature resistance, which can withstand long-term high-temperature environments and are not easily deformed or damaged.

[0003] With the continuous improvement of the performance and increasing power of modern industrial equipment, the heat generated is also increasing accordingly. This requires more effective heat dissipation and temperature equalization measures to ensure the normal operation of the equipment. However, if the existing graphite mold heating device is too large, it faces the problem of how to achieve uniform temperature distribution during the heating process to avoid local overheating or undercooling from adversely affecting the mold and product. In addition, the heat dissipation efficiency after heating is also poor, which leads to heat accumulation. When the temperature exceeds a certain limit, it may cause the graphite mold or surrounding materials to burn, posing a fire hazard. Utility Model Content

[0004] Therefore, this utility model proposes a graphite mold heating and temperature equalization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a graphite mold heating and temperature equalization device, comprising a heating container, two end caps respectively fixed to the left and right ends of the heating container, and a plurality of electrically heated graphite molds slidably disposed within the heating container, wherein each pair of adjacent electrically heated graphite molds is joined or separated by a spacing adjustment linkage mechanism, and each spacing adjustment linkage mechanism is disposed outside the heating container and is adapted to slide into a long slot on the side wall of the heating container. The spacing adjustment linkage mechanism includes:

[0006] Ear seat three, which is fixed to the side wall of the electrically heated graphite mold located on the left side;

[0007] The push cylinder's fixed end is rotatably connected to the lug seat three via a pivot pin three.

[0008] Ear seat one, which is fixed to the side wall of the electrically heated graphite mold located on the right side;

[0009] The elastic telescopic component has one end rotatably connected to the moving end of the push cylinder by a pivot pin two, and the other end of the elastic telescopic component rotatably connected to the ear seat one by a pivot pin one.

[0010] And a fixing rod, one end of which is fixedly connected to an electrically heated graphite mold located on the left side, and the other end of the fixing rod is rotatably connected to the elastic telescopic member by a positioning pin.

[0011] Furthermore, preferably, the distance between any two adjacent electrically heated graphite molds is set to be the same.

[0012] Furthermore, as a preferred embodiment, the elastic telescopic component is composed of ear seat two, inner slide rod, sliding pin, rotating cylinder and spring, wherein the bottom end of the inner slide rod is adapted to slide inside the rotating cylinder, and a sliding pin is fixed on the side wall of the bottom end of the inner slide rod, which is adapted to slide in the limiting slide groove on the side wall of the rotating cylinder, and ear seat two is fixed at the top end of the inner slide rod.

[0013] A spring is fitted on the side wall of the inner slide rod, between the ear seat and the rotating cylinder.

[0014] Furthermore, as a preferred embodiment, a slot for rotatably connecting with the fixed rod is provided on the rotating cylinder near its central portion.

[0015] Furthermore, preferably, the fixing rod is perpendicular to the electrically heated graphite mold.

[0016] Furthermore, as a preferred embodiment, the maximum length of the inner slide rod that can slide into the rotating cylinder is less than the length of the limiting slide groove.

[0017] Furthermore, preferably, the electrically heated graphite mold includes:

[0018] A graphite mold cylinder, inside which an insulation cylinder is installed;

[0019] And a spiral support frame, which is connected between the graphite mold cylinder and the outer shell, wherein an induction coil in contact with the graphite mold cylinder is arranged in the spiral channel of the spiral support frame.

[0020] Furthermore, as a preferred embodiment, the outer shell is made of ceramic material, and the outer diameter of the outer shell is the same as the inner diameter of the heating container.

[0021] This utility model adopts the above technology and has the following beneficial effects compared with the existing technology:

[0022] In this utility model device, the extension or retraction action of the push cylinder is controlled to drive the elastic telescopic component to rotate clockwise or counterclockwise around the positioning pin. When the elastic telescopic component rotates counterclockwise, the inner slide rod is compressed to overcome the elastic force of the spring and then slides into the rotating cylinder to make room. At the same time, the rotation drives the electrically heated graphite mold located at the rear to move towards the electrically heated graphite mold located at the front until the two electrically heated graphite molds merge. When the elastic telescopic component rotates clockwise, the inner slide rod is no longer pushed, the spring rebounds and drives other parts to return to their original positions, thereby driving the electrically heated graphite molds to merge or separate, thereby achieving rapid and uniform heating and rapid heat dissipation of the electrically heated graphite molds.
