The invention relates to the technical field of electronic equipment, in particular to a mold and a machining method. The mold comprises a mold kernel, an insert and a mold core, wherein the mold kernel is of an integrated structure; the insert is installed at the end of the mold kernel, and a cavity is formed by the insert and the mold kernel; at least part of the mold core extends into the cavity and is matched with the cavity for machining a product; the mold kernel is provided with a first air path; and cold air enters the cavity through the first air path, so that a gap is formed between the product in the cavity and the mold kernel. Due to the fact that the mold kernel is of the integrated structure, the machined product cannot form a clamping line in the prior art, and the appearance of the product cannot be affected. And the mold kernel is provided with the first air path, and cold air enters the cavity through the first air path, so that the product is cooled and contracted inwards, the gap is formed
