Embodiment Construction

[0017] The problem to be solved by the invention is the problem of long cooling time, long production and processing time and low production capacity in the current hot pressing method.

[0018] The technical solution adopted by the present invention to solve the problems of the technologies described above is as follows:

[0019] A hot pressing method of heating and extruding a workpiece in a heated mold, and then performing hot pressing in the order of cooling the workpiece in the mold by cooling the mold, characterized in that, Include the following steps:

[0020] 1) Pre-heating, pre-heating the mold;

[0021] 2) Moving in, moving the first workpiece into the heated first mold;

[0022] 3) In the first step of hot pressing, the first workpiece is heated and extruded in the heated first mold, and then the first mold is cooled to cool the workpiece in the first mold. the first artifact described;

[0023] 4) unloading, unloading the first workpiece from the cooled first ...

Abstract

The invention discloses a method and particularly discloses a hot-pressing method. According to the hot-pressing method, hot-pressing working is conducted in the sequence of heating and extruding a workpiece in a heated mold and then cooling the mold so as to cool the workpiece in the mold. The hot-pressing method is characterized by including the following steps of primary preheating, inward moving, primary hot pressing, outward moving, secondary preheating, inward moving which refers to moving a second workpiece into a heated second mold, secondary hot pressing, and outward moving. The hot-pressing method has the beneficial effects that the primary preheating step and the secondary hot pressing step are conducted in a parallel mode, and the secondary preheating step and the primary hot pressing step are conducted in a parallel mode. By means of the hot-pressing method, the cooling time is shortened, and production capacity is improved.

Description

technical field [0001] The invention relates to a method, in particular to a hot pressing method. Background technique [0002] Hot pressing forming is an important forming method, but the current hot pressing forming method has common problems: it is suitable for mass production, and the cooling time is long, the production and processing time is long, and the production capacity is low. [0003] Therefore, inventing a kind of heat pressing method that shortens cooling time and improves production capacity has become a problem to be solved urgently by people in the text field. Contents of the invention [0004] The invention proposes a hot pressing method, aiming at the deficiencies of the prior art, the hot pressing method can shorten the cooling time and improve the production capacity. [0005] The technical solution adopted by the present invention to solve the problems of the technologies described above is as follows: [0006] A hot pressing method of heating and ...
