Embodiment Construction
[0045] Examples, see Figure 1~3 , an exhaust structure 1 is composed of two different dense materials combined by additive manufacturing technology into one structure, and the two different dense materials are respectively a low-density exhaust part 2 and a high-density base part 3. The density of the base part 3 is higher than that of the exhaust part 2, and the density of the base part 3 is 90%-100%.
[0046] The overall shape of the exhaust structure 1 can be made into a regular shape or an irregular shape according to requirements, that is, the shape of the exhaust structure 1 can be set as a conformal structure according to the workpiece to be formed and processed.
[0047] The thickness of the exhaust part 2 is greater than or equal to 0.02mm. The exhaust part 2 is manufactured by additive manufacturing technology, and the exhaust part 2 is a loose structure 20; the loose structure 20 is provided with an air collection and exhaust structure 4, and the air collection an...

Abstract
The invention discloses an exhaust structure. The exhaust structure is characterized in that two materials with different densities are combined into an integral structure through the additive manufacturing technology, and the two kinds of materials with different densities are an exhaust part with low density and a base part with high density. The exhaust part is manufactured through the additive manufacturing technology and is of a loose structure. The exhaust part is provided with a gas gathering and discharging structure, and the base part is provided with an air way and a follow-shape temperature control pipe. The invention further discloses an exhaust method. The exhaust structure and the exhaust method relate to the technical field of the exhaust structure; the exhaust part and the follow-shape temperature control pipe solve the problems that during existing injection molding machining or other molding machining, exhausting is poor, and temperature control is unstable, and the product molding quality is guaranteed; air blowing to the air way is carried out, and therefore impurities in the exhaust part is achieved, and the cleaning difficulty is reduced. The exhaust structure is manufactured through the additive manufacturing technology, the machining time is shortened, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of exhaust structures, in particular to an exhaust structure and an exhaust method. Background technique [0002] During the molding process, it is necessary to set up an exhaust system to discharge the internal air during the molding process. Many current exhaust systems use multiple steel sheets to form exhaust grooves, and set through holes under the exhaust grooves for exhaust. Since the exhaust system is manufactured by manually combining multiple steel sheets, the processing time Long, high cost, and artificial combination also has the gap size between the steel sheet and the steel sheet is indefinite, and the exhaust effect is poor, making the product prone to cloak (burr). [0003] The existing exhaust system will be blocked by the accumulation of impurities after long-term use, affecting the exhaust effect. Most of the cleaning methods are manual cleaning of the external impurities, which takes a l...
