Problems solved by technology

Therefore, due to the need to trim the edge of the screen, the manufacturing method of the filter screen assembly in the prior art has the problem of low qualified rate
[0012] In addition, in the process of trimming the blank of the filter screen assembly by manual cutting, the cutter for cutting the mesh material is easy to cut fingers. Therefore, the existing manufacturing method of the filter screen assembly also has a great potential safety hazard

Embodiment 1

[0048] In the first embodiment, the second cutting edge 322 is located outside the second parting surface 321, the first cutting edge 312 is flush with the first parting surface 311, and the second cutting edge 322 cooperates with the first cutting edge 312 to form a cutting edge. The position is above the first parting surface 311 and above the second parting surface 312 (with figure 2 For reference); according to actual needs, those skilled in the art can appropriately change the positions of the second cutting edge 322 and the first cutting edge 312, so that the cutting position formed by the cooperation of the second cutting edge 322 and the first cutting edge 312 is located at the first point Below the profile 311 .

[0049] In the filter screen assembly formed by injection molding with the mold provided in Embodiment 1, the side frame 210 is located on one side of the mesh body 100 . The mold provided by Embodiment 2 of the present invention can make the side frame 210...

Abstract

The invention discloses a mold for manufacturing a filter screen assembly and a manufacturing method thereof. The disclosed mold for manufacturing the filter screen assembly comprises first and second molds respectively comprising a first parting surface and a second parting surface. When the molds are combined, the first parting surfaces are matched with the second parting surfaces and the first and the second molds at least form a predetermined side framework cavity. The first and the second molds respectively comprise a first cutting edge and a second cutting edge; and the first and the second cutting edges are respectively of closed ring structures, and the size of the ring structure of the first cutting edge corresponds to the size of a netted body in the filter screen assembly. In a mold combining process, the first cutting edge is matched with the second cutting edge for cutting. When a filter screen assembly is manufactured via the molds, a procedure of finishing net edges is not needed after injection molding; and therefore, the damage of the filter screen assembly by the net edge finishing procedure is avoided and the product percent of pass in the manufacturing process of the filter screen assembly is improved.

Description

technical field [0001] The invention relates to an air conditioner filter screen technology, in particular to a mold for manufacturing a filter screen assembly, and also relates to a method for manufacturing a filter screen assembly. Background technique [0002] Air conditioners are of course widely used electrical appliances. The main function of the air conditioner is to cool or heat the air in the room or other predetermined spaces, so as to achieve the purpose of adjusting the air temperature. The process of an air conditioner to adjust the air temperature is generally: the air enters the predetermined space of the internal machine core through the air inlet; in the predetermined space, the air is heated or cooled, and then the heated or cooled air is exhausted through the air. Mouth discharge. [0003] In order to reduce the adverse effect of dust or other impurities in the air on the inner machine core of the air conditioner, a filter assembly is usually arranged in...
