Embodiment Construction
[0020] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] see figure 1 with figure 2 , the invention discloses a method for manufacturing a thermal shaping mold, comprising the steps of:
[0022] Step 100, blanking, placing the mold 3 to be shaped on the lower mold 2, and the upper mold 1 to press the mold 3 to be shaped.
[0023] Step 110, preheating, preheating the mold 3 to be shaped.
[0024] Step 120, hot extrusion. After the mold 3 to be shaped is heated to a preset temperature, the upper mold 1 and the lower mold 2 squeeze the mold 3 to be shaped. The preset temperature is 600°C-800°C, so that the mold is in a high temperature state, Reduce the internal stress of the mold and flatten the mold so that the deformed mold does not spring back af...
