Technical Field
[0001] This utility model belongs to the technical field of roasting equipment, and more specifically, it relates to a roasting equipment for investment casting. Background Technology
[0002] Investment casting, also known as lost-wax casting, typically involves creating a mold from fusible material, covering the mold surface with several layers of refractory material to form a shell, melting the mold and removing the shell to obtain a mold without a parting line. After high-temperature baking, the mold can be filled with sand and poured. Investment baking is an important step in precision casting, mainly used to transform the investment pattern into a refractory model and prepare it for subsequent metal pouring. The investment baking process includes dewaxing, baking, and cooling steps to ensure the quality and performance of the final casting. To facilitate the baking treatment of the investment pattern, a baking device is needed.
[0003] Based on existing technology, it has been found that most existing roasting equipment handles the casting mold by opening a discharge port on the side, resulting in the casting mold lacking roasting on one side during the roasting process. This leads to uneven heating of the casting mold surface during roasting, making it inconvenient to perform the roasting process. Utility Model Content
