Problems solved by technology

[0003] Traditional molds are manufactured by stamping process. Stamping refers to a processing method that uses the mold under the action of a press to apply pressure to the material at room temperature, separates and deforms the material, and obtains parts of a certain shape, size and precision. Insufficient process precision, unstable quality and poor toughness

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...

Abstract

The invention discloses a manufacturing method for a hot-shaped die. The method includes the steps that a die to be shaped is placed on a lower die, and the die to be shaped is pressed downwards through an upper die; preheating is performed on the die to be shaped; after the die to be shaped is preheated to be at a preset temperature, the upper die and the lower die extrude the die to be shaped; quenching and tempering are performed on the die after hot extrusion treatment; polishing is performed on the surface of the die after the hot treatment; acid pickling is performed on the polished die, and then the hot-shaped die is obtained. By the adoption of the method, under the state of high temperature, internal stress of the die is reduced, and the die is pressed flat, so that the deformed die does not rebound after being pressed flat, and the die has good toughness.

Description

technical field [0001] The invention relates to a method for manufacturing a mold, in particular to a method for manufacturing a thermal shaping mold. Background technique [0002] Mold is one of the most widely used process equipment in industrial production, and it is also the basis for industrial development. Mold is the basic process equipment for forming metal, plastic, rubber, glass, ceramics and other parts, and it is an indispensable tool for developing and realizing chip-free processing technology in industrial production. The mold is a kind of high-efficiency process equipment. Using the mold to form various materials can realize high-speed mass production, and can stably guarantee the quality of the parts and save raw materials under mass production conditions. Therefore, in modern industrial production, the application of molds is becoming more and more extensive, which is an important means and process development direction of contemporary industrial production...
